Definitions

  • the invention relates to a press for pressing powdered masses, in particular of metal powder, with at least one connecting rod and one Eccentric crank drive having a crankshaft for driving a Upper stamp unit according to the preamble of claim 1 and a Procedure for operating this press.
  • the object of the present invention is to provide a press of the generic type to further develop that the known from the mechanical presses and advantageous for the compression of the press powder sinusoidal movement and progressive force curve is connected with that by a comparatively simple Hydraulic drive technology brought advantages in terms of high flexibility of the Press and a press course approximating the ideal course at high Reproducibility of speed and position of the pressing tools.
  • the Energy consumption of this press should be in relation to that which it can produce Driving forces be small.
  • the press parameters are intended to optimize the Movement sequence and the power requirement can be easily adjusted.
  • a procedure for operating this press is to be specified.
  • the press according to the invention has one for driving its upper punch unit Eccentric crank drive on the at least one connecting rod (usually in pairs arranged) includes that at one end with the upper stamp unit and at its other end is eccentrically connected to a crankshaft.
  • the Connection to the crankshaft can, for example, via an eccentric disk be realized.
  • a gearwheel is non-rotatably connected to the crankshaft.
  • This Gear is of at least one, preferably two, worm screws rotatable, which are appropriately diametrically opposite with respect to the crankshaft and in turn from at least one motor, preferably each from one separate motor can be driven.
  • the movements of this press are managed by an electronic control. Essential characteristic of the invention It is that this electronic control is based on a reversing operation of the crankshaft is set up.
  • crankshaft is preferably used over an angular range rotated by less than 180 ° according to the reversing rotation of the Gear moves the upper punch unit due to the power transmission through the Connecting rods up and down, i.e. between the press position and the fill / eject position forth.
  • crankshaft in the case of the press according to the invention is therefore not complete Revolutions.
  • control is set up so that the preferably two hydraulic motors of the press with regard to their engagement in the
  • the circuit of the hydraulic medium can optionally be connected in parallel and in series. in the If two hydraulic motors are connected in parallel, half is used Flow through the engine, while in a series connection both engines run through the full volume flow. That means at unchanged hydraulic unit, the setting option of a normal or a twice the working speed. The latter is particularly the case with Compression of smaller parts with a low overall height is a very special advantage.
  • the press contains a die that can be passed through Hydraulic cylinder in path control can be moved in a controlled manner, as is the case with Hydraulic presses is basically known.
  • the press can be hydraulic include operable tool adapter. In these cases it is advisable to use one central electric motor to provide a hydraulic pump for the Upper stamp unit and another hydraulic pump for the hydraulic cylinders of the Drives die and / or the hydraulically operated tool adapter.
  • an electronic measuring system for recording the current position of the upper bear of the press, who receives the upper stamp unit, or also an electronic angle encoder to record the current Angular position of the crankshaft can be provided.
  • the particular advantage of the press according to the invention its movements Press tool parts are guided by the electronic control consists in that preferably over the hydraulically with simple means in terms Volume flow and pressure flow of the hydraulic medium that can be influenced very easily a direct influence on the drive of the eccentric crank drive can be taken can. Both the speed and the torque on the eccentric crank drive can therefore be influenced hydraulically very easily and precisely. Beyond that it is It is advantageous that the eccentric crank drive has a significant translation with regard to the press force that can be generated by the press. The needed Press force is naturally in the area of the bottom dead center of the upper punch unit the biggest. But this is precisely in this position of the press Gear ratio between driving force and pressing force also greatest. The leads to the drive power required for the press drive in comparison a hydraulic press equipped with the same maximum pressing force can be chosen much lower. This is also the whole Energy consumption significantly lower during a press cycle.
  • the press according to the invention allows cycle times that are still below that of one in usual way electromotive driven continuous mechanical Eccentric crank press. This is possible if the press control is like this is set that the stroke in each case well before reaching the top dead center of the Eccentric crank drive ended and then reversed. With a usual mechanical press, this path must always be followed fully.
  • the cycle time of a conventional mechanical press becomes essential co-determined by the necessary procedures when exposing the compact.
  • This belongs in particular to the need to maintain a load force during pulling off the die by a in the upper punch drive unit hydraulic cylinder / piston system is applied.
  • This cylinder / piston system must be operated continuously Return movement of the upper punch drive unit for an extension movement Maintain the load force and after removing the die Return to the starting position as quickly as possible.
  • This requires either a particularly powerful (expensive) hydraulic system or an adjustment the basic speed (speed) of the press to the time required for the movement of the cylinder / piston system.
  • the press according to the invention can be used without problems the speed of the upper punch drive unit in the area of the lower one Dead center can be greatly reduced or even temporarily kept at zero until the Compact is exposed. As a result, the hydraulic effort for the Cylinder movements for the load force can be kept very small. After this The upper punch drive unit can be shaped with the maximum possible Speed can be returned to its original position.
  • Another advantageous operation of the press according to the invention is then if the stroke in the area of the bottom dead center of the upper stamp unit so is set that the bottom dead center is passed a small distance.
  • the Press is operated in the range of a crank angle that is slightly over 180 ° (absolute angle). After reaching the end point, because of the basically reversing operation of the press the dead center at 180 ° inevitably run over again. That means that in an extremely simple way and Do a double press with maximum press force at bottom dead center for each Duty cycle takes place. This has a special feature with certain pressed parts Advantage.
  • FIG. 1 is a schematic illustration of a Press according to the invention in a sectional view, with only the drive one Upper stamp unit 2 (i.e. the upper bear of the press in which the upper stamp unit is stored) is reproduced.
  • This upper stamp unit 2 depending on the shape one or more upper punches of the pressed body to be produced are held, is slidably mounted in a machine frame 1 of the press.
  • the compact is in that of a die 9 and one in the machine frame 1 of the press e.g. firmly Supported lower stamp unit 8 enclosed mold cavity generated in the the upper punch or plunges when pressing.
  • One is expedient mechanical adjusting device 10 is provided, via which the output and End position of the upper punch unit 2 are adjustable.
  • an electronic rotary encoder On the crankshaft 4 is housed an electronic rotary encoder, not shown, with its The current position of the upper stamp unit 2 can be detected indirectly.
  • a hydraulic pressure system is provided, which is also not shown in detail and also the supply of additional hydraulics driven press tool parts (e.g. die, lower punch unit or Tool adapter). All movements of the press parts are carried out by an electronic control not shown in Fig. 1 performed the Valves and pumps of the hydraulic system based on the measured values of the Rotary angle encoder or the direct measuring systems used controls.
  • the eccentric crank drive in the lower Provides part of the machine frame 1, it should be in the practical execution of a Press according to the invention may be more advantageous, the eccentric crank drive to be arranged above the upper punch unit 2, i.e. in the top of the press. This does not change the basic functionality.
  • the two screws of the worm drives 6.1 and 6.2 are over the Hydraulic motors 7.1, 7.2 with the one supported by a hydraulic pump Hydraulic fluid acted on and effect according to the gear ratio Worm drives 6.1, 6.2 a torque on the gear 5 and a corresponding one Rotational movement of the crankshaft 4.
  • the electronic control is designed so that one by switching the direction of rotation of the hydraulic motors 7.1, 7.2 reversing rotary movement on the crankshaft 4 over an angular range of z. B. gives 120 °. With appropriate selection of the number of revolutions of the Hydraulic motors 7.1, 7.2 move the short drive to the lower area Dead center.
  • the control of the press can be set up so that depending on Requires a press end position beyond the bottom dead center of the connecting rod 3 becomes.
  • the absolute dead center of the press position is once in the actual work cycle and then again at the beginning of the "empty cycle" run over so that a double pressure is effected.
  • By shortening the rotation the crankshaft to an area well below 180 ° becomes the need avoided the relatively time-consuming valley and / or the mountain top of the sinusoidal Having to go through the movement curve completely. This can easily be done save about 30-50% of the cycle time.
  • Reversing operation in the sense of the present invention, but not in presses with the usual eccentric drive that performs complete complete rotations regularly.
  • the press thus advantageously combines a slow work trip with a large one Pressing force and a quick return trip with less force.
  • the drive power of the Press can be much more uniform in this way over the duration of the press cycle be used than is the case with a conventional hydraulic press.
  • the parallel or series connection also be maintained unchanged throughout the press cycle, the latter is particularly recommended for achieving high production output Pressed parts with a comparatively low height, for the lower press forces are sufficient.
  • the press according to the invention can also be used like a conventional mechanical press in continuous operation, i.e. without reversing the Operate drive motors. This still has the advantage of a light one Adaptability of the working speed.
  • an electronic control is provided, which is a path control with free programmable controlled positions and speeds allowed.
  • the sinusoidal course of the path covered by the upper stamp unit 2 as a function of time is shown at the top right in FIG.
  • the crankshaft rotation is 180 °, the upper punch unit 2 moving from top dead center OT to bottom dead center UT.
  • the time required for this (compression stroke) is denoted by t v . Since the subsequent return movement from bottom dead center UT to top dead center OT is not carried out in hydraulic parallel connection, but in series connection of hydraulic motors 7.1, 7.2, the crankshaft 4 rotates equally, but the time required is due to the constant delivery flow of the hydraulic pump has become smaller and is only t r .
  • the second part of the sine curve is therefore compressed accordingly in the direction of the time axis.
  • the dash-dotted lines and the +/- signs indicate in the graphic that the end position of the upper punch unit can be varied in the positive or negative direction in the area of the dead center.
  • the part of the work cycle in which the powder is compressed in the press mold is designated by A.
  • Figure 2 are in the sense of an embodiment depending on the crank angle ⁇ of the eccentric crank drive, the courses of some characteristic values of an inventive Press reproduced. Only the section in the area of Crank angle ⁇ from 130 ° to about 180 ° (bottom dead center) reproduced.
  • the selected example refers to a press in which the crank angle range from 130 ° to 180 ° corresponds to a travel of the upper punch unit by 40 mm.
  • the curve s of the travel path in FIG. 2 thus gives the distance between the Upper stamp unit from the bottom dead center. This travel distance corresponds approximately the actual pressing process in the press, i.e. the phase of powder compaction.
  • the curve labeled F shows the course of the actual pressing force at one representative press body again, which is the maximum that can be processed by the press Height. With increasing powder compaction, this pressing force F increases approximately a crank angle ⁇ of 140 ° strongly up to a value of 2340 kN in the lower Dead center.
  • the torque M d associated with the respective pressing force on the crankshaft has a size of 7125 Nm under the given dimensional relationships of the press at a crank angle of 140 °.
  • the torque then rises steeply and reaches its maximum at around 160 ° with a value of 45500 Nm.
  • the maximum pressing force is 1225 kN. After reaching the maximum, the torque drops sharply as the crank angle ⁇ increases and is zero at bottom dead center, while the pressing force reaches its maximum value.
  • the torque on the crankshaft is directly proportional to the torque of the hydraulic motors and thus to the hydraulic pressure.
  • the tangential shaft on gear 5 is at the maximum torque (45500 Nm) only 364 KN, while the actual pressing force F is 1225 kN.
  • the maximum possible Force transmission V in FIG. 2 is also a function of the crank angle ⁇ shown. Especially in the area of the last degrees of angle before reaching the bottom dead center there is a highly progressive increase in power transmission V.
  • the drive proposed by the invention is particularly advantageous for the Upper punch unit used in powder presses, their other levels of movement (Die, tool adapter) are also hydraulically driven and some have a common main drive motor for the hydraulics.
  • This is special expedient because the power requirement for the upper stamp unit and As a rule, the matrix does not line up at the same time but one after the other larger momentum of a central drive to reduce the peak power the upper punch unit in the range of a crank angle of approximately 160 ° and later on bottom dead center (crank angle 180 °) is beneficial when tearing the die.
  • the Press according to the invention provides a sinusoidal movement and force curve, enables high accuracy in the compacts to be produced, has one high efficiency, is extremely flexible with regard to the producible parts, increased the production performance clearly and brings a significant advance in the Manufacturing technology.
