Description

Detailed Description of the Invention (Industrial Application Field) The present invention is an automatically controlled spinning processing device used for manufacturing various axially symmetrical metal sheet products, that is, spinning a metal sheet into a rotating mold. The present invention relates to an automatically controlled spinning processing device that processes a shape along the outer circumferential surface of the mold by pressing it with a roller.

(Prior art) In recent years, automatic control spinning processing equipment using a hydraulic profiling device that uses a spinning roller that automatically moves hydraulically along a profiling die instead of a forming spatula has been widely used. The equipment must have a gauge adjustment that strictly sets a clearance between the mold and the spinning roller that corresponds to the thickness of the material metal plate, and if the accuracy is low, the thickness of the material metal plate may become uneven. Because tears, molding wrinkles, etc. occur, it takes an extremely large amount of time and effort to adjust the gauge, and not only does it require a precise copying die that matches the mold, but it also requires a spinning roller to be used in the copying die. The cost is extremely high because it requires complex mechanisms such as servo mechanisms for high-precision tracing, and it is also necessary to readjust the clearance in response to changes in mold diameter due to temperature changes. There were various problems such as these, and it was particularly unsuitable for low-volume, high-mix production.

In order to solve these problems, the applicant previously proposed a spinning processing apparatus that does not use the copying die as described above. This spinning processing device includes two hydraulic cylinders that separately move the spinning roller in a direction parallel to the rotation center axis of the mold and in a diagonal direction relative to the axis, and two controls that separately control both hydraulic cylinders. Equipped with an operating lever to operate the valve,
By operating the control valve with this operating lever, the two hydraulic cylinders are driven so that the spinning roller moves along the mold, and the spinning roller applies a constant pressure to the material metal plate into the shape along the mold. It is configured to perform spinning processing.

(Problems to be Solved by the Invention) The above-mentioned spinning processing apparatus has been able to solve various problems in spinning processing apparatuses that require copying dies, but it is difficult to process each product one by one. Since the operating lever must be manually operated at each step, not only is it impossible to streamline the process, but there is also the risk of variations in product quality.

(Means for Solving the Problems) The present invention proposes an automatically controlled spinning processing device capable of solving the above problems, and its feature is that the spinning roller is aligned with the rotation center axis of the mold. a screw feeding mechanism that reciprocates in a direction parallel to the rotation axis of the mold, and a hydraulic cylinder that reciprocates the spinning roller in a diagonal distance direction with respect to the center axis of rotation of the mold, and an operating lever of a control valve that controls the hydraulic cylinder. A lever driving means for driving a motor in the operating direction thereof is provided, and an operating means for controlling the drive motor of the screw feeding mechanism is provided, and the spinning roller is driven by operating the control valve operating lever and the motor control operating means. means for detecting and storing changes in the position of the control valve operating lever and changes in the feed position of the screw feeding mechanism when spinning is performed; The feature is that a controller is combined to automatically operate the motor of the drive means and the screw feed mechanism drive motor.

(Operation of the Invention) In the above-described apparatus of the present invention, prior to performing automatic spinning processing, a teaching operation is performed by manually operating the control valve operation lever and the motor control operation means. That is, by operating the control valve operating lever, the hydraulic cylinder can be driven to move the spinning roller in a diagonal direction relative to the rotation center axis of the mold, and by operating the motor control operating means, the screw feed can be moved. Since the spinning roller can be moved in a direction parallel to the rotation center axis of the mold by driving the mechanism, the material metal plate set in the mold can be moved by appropriately combining and operating the operating lever and the operating means. can be processed by the spinning roller into a shape that follows the mold.

During this teaching work, changes in the position of the control valve operating lever and changes in the feed position of the screw feed mechanism are detected and memorized, so that the next time the lever is adjusted based on the memorized data. The motor of the drive means and the screw feed mechanism drive motor are automatically operated by the controller. That is, the hydraulic cylinder that moves the spinning roller obliquely in the far and near directions with respect to the rotation center axis of the mold is operated manually (during teaching work) by the motor of the lever driving means.
The screw feeding mechanism is actuated based on the movement of the control valve operating lever which is driven in the same manner as the above, and moves the spinning roller in a direction parallel to the rotation center axis of the mold. Operated by direct control of the motor. As a result, the spinning roller can be moved in exactly the same manner as during the teaching operation, and the same spinning process as during the teaching operation can be performed.

As shown in FIGS. 3 to 5, the operation lever 16 of the flow rate proportional control valve V ₃ is connected to the valve body operation rod 20 of the flow rate proportional control valve V ₃ that can swing in the direction of F-B from L to R. They are connected via a support shaft 21 so as to be able to swing only in the direction, and a switch operation part 22 that protrudes in the FB direction is provided near the lower end. Although not shown in the figure, there is a spring at the pivot point between the valve body operating rod 20 and the operating lever 16 that holds the operating lever 16 at a neutral position in the L-R direction with respect to the valve body operating rod 20. is attached. LSL is a limit switch that is operated by the switch operating section 22 when the operating lever 16 is tilted to the left from the neutral position using the support shaft 21 as a fulcrum, and LSR is a limit switch that is operated by the switch operating section 22 when the operating lever 16 is moved from the neutral position to the support shaft 21. This is a limit switch that is operated by the switch operation section 22 when the switch is tilted to the right using the fulcrum.

As shown in FIG. 6, the pulse encoder
The oscillation pulses of PE1 and PE2 and the detection signals of each limit switch LSL, LSR, LSF, LSB, etc. are input to the system controller 33 using a microcomputer 31 and a sequencer 32, and are used to drive the screw shaft of the screw feeding mechanism 12. and the drive motor M of the operating lever drive means 23.
2nd place is motor controller 34, 35 respectively.
It is automatically controlled by the system controller 33 via the system controller 33. In addition, the input system of the system controller 33 includes teaching/automatic operation mode selection switches SW ₁ and SW ₂ and a start button SW _3.
etc. are connected.

Next, the contents of the control program set in the sequencer 32 will be explained based on the flowchart of FIG. 7. In addition, the first slide stand 8 is waiting at the backward limit in the R direction (rightward limit), and the second slide stand 9 is waiting at the backward limit position in the B direction, and the position of the spinning roller 5 at this time is the origin. It is becoming. In addition, the sequencer 32 is set with a process order such that the first process is rough drawing and the second process is finishing process, and the leftward speed and rightward speed ( (rotational speed of motor M1) is set.

When the start button SW ₃ is turned on with the spinning roller 5 at the origin, the motor M2 of the operating lever driving means 23 is driven in the forward direction, and the motor M2 of the operating lever driving means 23 is driven to rotate in the forward direction. The operating lever 16 is driven in the F direction to the forward limit position. As a result,
The flow proportional control valve V ₃ is driven and the hydraulic cylinder
_C3 causes the second slide table 9 to move forward at high speed in the F direction to the forward limit position as shown in FIG. When the movable base 25 reaches the forward limit position and the limit switch LSF turns ON, and the second slide base 9 reaches the forward limit position, the motor M1 of the screw feed mechanism 12 is rotated at a preset low speed. The first slide table 8 is rotated and moved forward at a low speed in the L direction (leftward direction toward the mold 2) from the R direction retraction limit position. At the same time, the motor M2 is switched to a free state in which the operating lever 16 can be freely operated in the FB direction.

Therefore, by manually operating the operating lever 16 in the FR direction to control the flow rate proportional control valve _V3 , the second slide base 9 is driven in the FR direction via the hydraulic cylinder _C3 , The spinning roller 5, which is moving leftward at low speed, can be moved in the FR direction at any speed. At this time, if the rough drawing process is set, the operation lever 16 can be used to switch the first slide table 8 to high-speed movement, and also to arbitrarily change the direction of movement.

That is, by tilting the operating lever 16 in the R direction and turning on the limit switch LSR, the screw feeding mechanism 12
Motor M1 is released from automatic operation (low-speed normal rotation leftward drive). After this, while the operating lever 16 is tilted in the L direction (while the limit switch LSL is ON), the motor M1 is driven forward at high speed, and while the operating lever 16 is tilted in the R direction ( While the limit switch LSR is ON), the motor M1 is driven in reverse at high speed. Therefore, after the first slide table 8 (spinning roller 5) starts moving to the left at low speed due to automatic operation as described above, once the operating lever 16 is tilted in the R direction (right side), it immediately moves in the L direction (left side).
By tilting it down, the first slide table 8 (spinning roller 5) can be switched from low speed to high speed and moved to the left.
By tilting it in the direction (to the right), the first slide table 8
(The spinning roller 5) can be moved rightward at high speed. To stop the high-speed movement of the first slide table 8 (spinning roller 5) in the LR direction, the operating lever 16 may be returned to the neutral position to stop the motor M1.

Therefore, in the rough drawing process, as described above, by once performing the automatic operation release operation by tilting the operating lever 16 in the R direction (right side), the operating lever 16 is then operated in the L-R direction and the F-B direction. Thus, the spinning roller 5 can be freely moved on a flat surface. Of course, it is possible to move at high speed in the L-R direction, and at any speed in the F-B direction.

When the operating lever 16 is tilted in the B direction and the interlocking movable base 25 turns on the limit switch LSB, the second slide base 9 is moved to the backward limit position in the B direction by the hydraulic cylinder _C3 via the flow rate proportional control valve _V3 . At the same time, the motor M1 of the screw feed mechanism 12 is driven in reverse to move the first slide table 8 backward at high speed to the backward limit position in the R direction, and the spinning roller 5 is returned to its origin. That is, the operation of tilting the operating lever 16 in the B direction to the stroke limit is the operation of returning the spinning roller 5 to its origin.

When the spinning roller 5 returns to the origin, it is checked whether the next process such as a finishing process is set, and if there is no next process, the process ends, and if there is a next process, the above control program is executed again.

When performing the actual spinning process, first, the forming die 2 is attached to the main spindle 1a, and the tailstock 4 is attached with the center hole of the metal plate material W fitted into the protrusion 2b of this forming die 2, as shown in FIG. the hydraulic cylinder
Move the metal plate W forward by C ₂ , clamp and fix the metal plate W between the tailstock shaft 4a and the front end surface of the mold 2, and then bring the back up roller 17 into contact with the back edge of the metal plate W. Advance to position by hydraulic cylinder C ₄ .

Next, by turning on the teaching selection switch SW ₁ and pressing the start button SW ₃ , the second slide table 9, which is waiting at the backward limit position in the B direction, is moved forward in the F direction, as shown in the flowchart of FIG. After forward movement to the limit position, the first slide table 8 is automatically moved forward in the L direction at a low speed by the above-described sequence control. Then, by the sequence control, the operating lever driving means 2
Motor M2 of No. 3 becomes free, and operation lever No. 1
6 can be freely operated in the FB direction, the teaching operation is started.

That is, as described above, the operating lever 16 is operated to move the spinning roller 5 at high speed in the L direction at the F direction advance limit position, and the metal plate W rotates integrally with the mold 2 as shown by the imaginary line in FIG. The spinning roller 5 is brought into contact with a position near the center of rotation. From this state, the operating lever 16 moves the spinning roller 5 in the L direction and backward in the B direction as shown in FIG. 11, thereby drawing the metal plate material W toward the mold 2. This drawing process is repeated several times to finally form the metal plate material W into a shape that follows the outer peripheral surface of the mold 2. At the stage of pressing the metal plate material W against the mold 2 with the spinning roller 5, the relief valve The operating lever 16 must be operated so that the spinning roller 5 presses the metal plate material W against the mold 2 with a constant pressure by _V4 . When the spinning process is completed, as described above, the operating lever 16 is pushed down to the backward limit in the B direction to return the spinning roller 5 to its origin, and if there is a next step, the above teaching operation is repeated.

During the teaching operation in each of the above steps (spinning processing by manual operation of the operating lever 16), the operating lever 16 is moved in the F-B direction based on the teaching program stored in the internal memory (ROM) of the microcomputer 31. Change in position and change in feed position in the screw feed mechanism 12 (change in position of first slide table 8)
is detected and the microcomputer 31
stored in the internal memory (RAM).

That is, the movable base 25 is linked to the movement of the operating lever 16 in the F-B direction, and the pulse encoder PE2 is driven via the rack gear 28 and pinion gear 30. For example, when the operating lever 16 moves backward in the B direction (when the pulse encoder reverses), it is subtracted from the preset value when the operating lever 16 reaches the forward limit position. By counting to add up when moving forward,
A pulse count value corresponding to the position of the operating lever 16 in the FB direction is obtained. This pulse count value is used as the position data of the operating lever 16 in the F-B direction, and the pulse count value is used as the position data of the operating lever 16 in the F-B direction, and the
It is imported into the internal memory (RAM) of the microcomputer 31 and stored.

In addition, the first slide table 8 is moved by the screw feed mechanism 12.
When the slider 8 is driven, the pulse encoder PE1 is driven by the rotating screw shaft 15, so the oscillation pulse of the pulse encoder PE1 is preset when the first slide base 8 reaches the backward limit position in the R direction. The value is added when the first slide table 8 moves forward in the L direction (when the pulse encoder rotates forward), and subtracted when the first slide table 8 moves backward in the R direction. By counting, a pulse count value corresponding to the position of the first slide table 8 in the LR direction can be obtained. This pulse count value is
The position data in the -R direction (feed position data of the screw feed mechanism 12) is captured and stored in the internal memory (RAM) of the microcomputer 31 at preset fixed time intervals, for example, every 50 ms.

After the teaching is completed, the sampling data stored in the internal memory can be transferred to external storage means such as a floppy disk.

When performing spinning processing in automatic operation after the manual operation for teaching is completed as described above, press mode selection switch SW ₂ to select automatic operation. At this time, when using the control data stored in the storage medium of the external storage means, the control data is transferred from the floppy disk etc. set in the external storage means to the microcomputer 3.
1 to the internal memory (RAM), and press the start button SW ₃ when processing preparations are complete. As a result, automatic operation is performed as shown in the flowchart of FIG. 9 based on the automatic operation program stored in the internal memory (ROM) of the microcomputer 31.

That is, as in the teaching, the second slide stand 9, which is waiting at the backward limit position in the B direction, is moved forward to the forward limit position in the F direction, and then the first slide stand 8 is moved forward at low speed in the L direction. The steps up to this point are automatically performed by the sequence control described above. After this, control data is read out from the internal memory (RAM) at regular intervals that are the same as the sampling time interval of the control data during teaching, and based on this read control data, the screw feeding mechanism is controlled via the motor controllers 34 and 35. 12 drive motors M1 and operating lever drive means 2
The drive of the motor M2 of No. 3 is controlled. As a result, the first slide table 8 sequentially moves to a target position given at regular intervals as the screw shaft 15 driven by the motor M1 rotates, and the operating lever 16
is successively moved to a target position given at regular intervals as the movable base 25 is driven by the motor M2 via the pinion gear 29 and the rack gear 28. That is, the first slide stand 8 is moved in the L-R direction in exactly the same way as when the operating lever 16 is operated in the L-R direction during teaching to move the first slide stand 8 in the L-R direction. become. Further, the operating lever 16 is moved in the F-B direction by the operating lever driving means 23 in exactly the same way as when the operating lever 16 is manually operated in the F-B direction during teaching. Therefore, F is controlled by the flow rate proportional control valve _V3 controlled by this operation lever 16 and the hydraulic cylinder _C3 .
The second slide table 9 driven in the -B direction also moves in the same way as during teaching.

With such automatic control, the spinning roller 5 moves in the same manner as during teaching, and automatically spins the metal plate material W set in the mold 2 in the same manner as during teaching. Of course, after one process is completed and the spinning roller 5 automatically returns to the origin, if the next process is set, the next process is automatically started.

In the above embodiment, during both teaching and automatic operation, after the second slide table 9, which is waiting at the backward limit position in the B direction, is moved forward to the forward limit position in the F direction, the first slide table 9 is moved forward to the forward limit position in the F direction. Although the sequence control described above automatically moves the slide table 8 forward at a low speed in the L direction, this is not an essential requirement for the present invention. That is,
Teaching (sampling of position data) is performed by driving the first slide stand 8 and the second slide stand 9 by operating the operating lever 16 from where the spinning roller 5 is waiting at the origin position.
Spinning roller 5 at the home position even during automatic operation
The first slide stand 8 and the second slide stand 9 may be driven based on the control data while the slide stand is waiting. Further, although the operating lever of the control valve and the operating means for controlling the drive motor of the screw feeding mechanism are configured by a common operating lever 16,
For example, as the operating means for controlling the drive motor of the screw feeding mechanism, it is also possible to use an operating lever other than the control valve operating lever, a push button switch, or the like.

Further, the knockout pin 3, the tailstock 4, the back up roller 17, the workpiece support base 18, etc. can also be configured to be driven automatically. Furthermore, the spinning process is not limited to the drawing spinning of the above embodiment. For example, the apparatus of the present invention can also be applied to various other types of spinning processes, such as handling spinning (shear spinning) and cylindrical spinning. Also, depending on the processing method, the back up roller 17 can be omitted.

(Effects of the Invention) As described above, in the automatically controlled spinning processing apparatus of the present invention, the spinning roller is operated in exactly the same manner as when manually operated based on the data when the processing apparatus is manually operated by manual operation of the control valve operating lever. Since the spinning process can be automatically moved to the next position, it is possible to automatically repeatedly manufacture spun processed products with consistent quality. Therefore, it is also effective in mass production of the same product.

Moreover, according to the configuration of the present invention, since the operating lever that directly drives the control valve is moved by the driving means in the same way as when manually operated, the joystick-like operating lever for obtaining the electric signal to control the control valve is moved. Compared to the case of using the spinning machine, the operation during teaching can be easily performed with the same feeling as the operation of a conventional manually operated spinning processing apparatus, and the operability is improved.

Furthermore, a screw feed mechanism is used instead of a hydraulic cylinder to move the spinning roller in the direction of the rotation center axis of the mold, and changes in the feed position of this screw feed mechanism are directly detected and stored. Since the motor of the screw feeding mechanism is configured to be directly controlled based on the data, the operating means (also used as a control valve operating lever in the example) for controlling the drive motor of the screw feeding mechanism can be mechanically operated in the same way as during teaching. This eliminates the need for a drive means to operate the system, and can be implemented at low cost. Furthermore, the position of the spinning roller in the direction of the mold rotation center axis during automatic operation can be controlled with extremely high precision.
