Description

[Detailed Description of the Invention] a. Field of Industrial Application The present invention relates to a device for sliding down a plate material that has been sheared by a shearing machine and falls backward.

B. Prior Art Conventionally, as a device for carrying out backwards the plate material sheared by a shearing machine, there are a structure in which the sheet material is carried out by a belt conveyor, a structure in which a shutter is provided and the sheet material is slid down by its own weight, etc.

c Problems to be solved by the invention In the conventional configuration in which plate materials are carried out using a belt conveyor, if the sheared plate materials fall directly onto the belt conveyor, there is a risk of damaging the belt conveyor. Some machines have a configuration in which the plate material is delivered to the belt conveyor after receiving the plate material at the shearing machine, but in this configuration, when positioning the plate material by contacting it with the back gauge of the shearing machine, it is possible to adopt a structure in which the plate material is supported. The problem is that it is quite difficult.

Further, in a configuration in which a shutter is provided and the shutter slides down due to its own weight, there is a problem in that the plate material may fall directly onto the shutter and damage the balls, rollers, etc. provided in the shooter.

d Means for solving the problem In order to solve the above-mentioned conventional problems, this invention is a device that supports the falling plate material that is sheared by the shearing machine and slides it backwards, and the shearing machine has a device that can freely move back and forth. A chute plate is disposed below the back gauge and is movable between a horizontal position supporting the sheared and falling plate material and a downwardly inclined position tilting backward, and the plate material abutting against the back gauge is provided. A plate support arm equipped with a support roller that supports the plate is placed in a horizontal position in which it protrudes upward from the gap between the shute plates in the horizontal position to support the plate, and in a horizontal position below the chute plate in the horizontal position and tilted downward. It is provided so as to be freely displaceable between a position above the chute plate in the state position and a downwardly inclined state position in which it is inclined rearward and downward.

e. Effect With the above configuration, by holding the plate support arm in a horizontal position, the plate that comes into contact with the back gauge can be supported by the support roller. When shearing a plate, the plate support arm is lowered to receive the sheared plate with the horizontal chute plate, thereby preventing the plate from coming into contact with the support roller of the plate support arm and being damaged. When the chute plate receiving the plate material is lowered and tilted backward, the plate material is delivered onto the support roller of the plate material support arm, and the plate material slides backward due to its own weight and is carried out.

f Embodiment FIG. 1 shows an example in which the device 1 for supporting and sliding a plate according to the present invention is implemented in a shearing machine 3.

The shearing machine 3 has a table 5 shown on the left side of the figure, a lower frame 9 below the gap part 7 and an upper frame 11 above the gap part 7. A ram 13 is provided which is raised and lowered by an omitted drive mechanism.

At the back end of the table 5 is a lower blade 15, a ram 13
An upper blade 17 is provided on the front edge of the blade.

A plate holder 19 is provided at the front end of the upper frame 11 to fix the workpiece W between it and the table 5. A back gauge 23 is also provided which is supported by a horizontal ram brace 21 and moves back and forth (left and right in FIG. 1) to determine the width (length in the depth direction) of the material to be cut.

Figure 1 shows a back gauge 2 in which the workpiece W is inserted from the front of the table 5 and the back gauge 2 occupies the desired cutting width position.
3 is a diagram showing a state in which it is applied.

In order to support the plate material in contact with the back gauge 23, support rollers 27 are respectively provided on a plurality of elevating levers provided on the plate material support arm 25 so as to be able to freely move up and down. In this configuration, for example, four sets of support rollers 27 are driven by the piston rod 31 of the hydraulic device 29 to occupy the upper limit position, thereby preventing the workpiece W from hanging down at the rear (near the back gauge).

Furthermore, when the desired cutting width is short, the back gauge 23 occupies a position moved to the left side in FIG. One bearing roller 27 is moved to the lowered position.

FIG. 2 is a plan view of the lower frame 9, in which a plurality of shoot plates 37 swing around a horizontal shaft 35 provided on the table 5 side of the lower frame 9, and change from the horizontal state shown in FIG. The rear of the shearing machine 3 shown in the figure (right side in Figures 1, 3, and 4) is displaced to a downward slope state where it becomes lower.

The width of the plurality of chute plates 37 gradually increases from the right end side to the left side in FIG. This is to support it.

The driving device for driving the shoot plate 37 includes a fluid pressure cylinder 39, a piston rod 41, a link 43,
A plurality of links 47 are oscillated via a rotation shaft 45, and each link 49 simultaneously drives the substantially central lower part of each shoot plate 37 to oscillate by the same amount.

The plate support arm 25 described above rotates around a fluid pressure cylinder 51, a piston rod 53, a link 55, and a rotation shaft 57, and is connected to the rear side of the plate support arm 25 (Figs. 1, 3, and 4) by an appropriate number of links 59. right side)
is raised and lowered.

At the same time, the front rotation shaft 69 is rotated near the bearing block 61 of the rotation shaft 57 shown in FIG. 2 via the link 63, the horizontal link 65, and the vertical link 67 attached to the rotation shaft 57. The plate material supporting arm 2 is
The middle bottom part of 5 is raised and lowered.

As is clear from FIG. 4, when the piston rod 31 is driven by the hydraulic device 29 and displaced to the lower limit position, the support roller 27 does not rise or fall.
It occupies the same upper surface inclined position as 7', and protrudes above the upper surface of the inclined chute plate 37.

The procedure for processing a plate material using the apparatus of the above embodiment is as follows.

First, with the plate presser 19 raised, the back gauge 23 is moved and positioned at a desired cutting width position.

In this case, if there is a support roller 27 that interferes with the forward movement of the back gauge 23, the detection device 33 detects the approach of the back gauge 23 and drives the hydraulic device 29 of the interfering support roller 27 to prevent the support roller 27' from rising or lowering. Lower to a lower height.

Next, the back end of the workpiece W is placed against the back gauge 23, and the workpiece W is fixed on the table 5 with the plate holder 19. During this time, the free end of the workpiece W is supported by the support roller 27 and does not sag, ensuring an accurate cutting width.

After fixing the workpiece W, the support roller 27
are all lowered to a low position, and the fluid pressure cylinder 51 is driven to lower the plate support arm 25 to the processing position and tilt it rearward, resulting in the state shown in FIG.

However, the chute plate 37 remains in a horizontal position.

The ram 13 is driven to perform shearing work.

The cut plate material is received by the horizontal chute plate 37.

Next, when the fluid pressure cylinder 39 is driven to swing the chute plate 37 to the state shown in FIG. It is.

g. Effects of the invention As can be understood from the explanation of the examples above, the gist of the invention is as stated in the claims for utility model registration, and as is clear from the description, the invention The chute plate 37, which supports the plate material falling after being sheared by the shearing machine, is movable between a horizontal position supporting the plate material and a downwardly inclined position tilting backward. In addition, the plate material support arm 25 equipped with a support roller 27 that supports the plate material that comes into contact with the back gauge 23 has two positions: one in a horizontal position in which it protrudes upward from the chute plate 37 and supports the plate, and the other in a horizontal position below the chute plate 37 in the horizontal position. It is freely displaceable between the position and the downwardly inclined position in which it is inclined rearward and downward at a position above the chute plate 37 in the downwardly inclined position.

Therefore, in the present invention, when shearing a plate, the plate is supported by the support roller 27 of the plate support arm 25 and the plate is placed on the back gauge 2.
3, by holding the chute plate 37 in a horizontal position and holding the plate material support arm 25 in a downwardly inclined state, the sheared and falling plate is received by the chute plate 37, and the plate material support arm 25 is held in a downwardly inclined state. This prevents the arm 25 from falling directly into contact with the support roller 27, thereby protecting the support roller 27. Further, when the chute plate 37 that has received the plate material is displaced to a downwardly inclined state, the plate material supporting arm 25 is in a state where the plate material on the chute plate 37 is inclined backwardly downward.
It is supported by supporting rollers 27, and slides down smoothly even under its own weight.

That is, in the present invention, the support roller 27 is
This roller serves both as a roller for supporting the plate material when it comes into contact with the back gauge 23 and as a roller for carrying out the plate material, and is protected by the chute plate 37.
