Definitions

  • the application relates to a forming press with at least one pair of tools, each consisting of a punch and a die, each punch being supported on the press slide by means of a pressure piece which can be displaced in the direction of movement of the press slide by means of an adjusting device which can be actuated by a spindle.
  • Forming presses are known in which the press rams are supported on the back of each pressure piece, which can be displaced in the direction of movement of the press slide via an adjusting device. In this way, the position of the ram can be adjusted to different workpieces.
  • Each adjusting device consists of an adjusting wedge that can be moved via a spindle, on which the pressure piece, which is also wedge-shaped on its back, is supported. By moving the adjusting wedge perpendicular to the axis of the ram, the pressure piece changes its position.
  • the spindles of the adjustment device are removed from the adjustment process after loosening the lock nuts Turned by hand and then fixed again with the lock nuts. This is cumbersome and time-consuming, especially in the case of multi-stage forming presses.
  • the invention is therefore based on the object, the displacement of the stamp in forming presses of the type mentioned significantly easier.
  • the adjusting device is provided with a motor for driving the spindle.
  • the spindle of each adjustment device can be adjusted by remote control, the interruption of the press operation being extremely short.
  • the motor is arranged on the press frame and a coupling device for connecting the motor to a gearwheel seated on the spindle is provided in a specific position of the press slide.
  • the coupling device can consist of a pinion connected to the motor, which is movable for the engagement position in the range of motion of the press slide. The movement of the pinion can take place via an actuating piston which can be acted upon by pressure medium against the action of a spring.
  • the pinion is normally held outside the range of movement of the press slide and the engagement position is only established when a pressure medium is applied to the actuating piston.
  • the arrangement can be made that the pinion is attached to a bolt seated in a drive sleeve, which is rotatably connected to the drive sleeve via a slide spring.
  • the coupling device should expediently be arranged on the press frame in such a way that the engagement position results when the press slide is retracted completely, since this position is the easiest to reproduce.
  • the spindle be provided with a hydraulically actuated clamping sleeve for fixing the setting of the pressure piece.
  • This clamping sleeve can also be controlled remotely like the motor, so that the spindle can be loosened and fixed quickly and easily.
  • the motor for driving the spindle is preferably designed as a servomotor, since these motors are particularly suitable for the present purpose.
  • the invention provides that in the case of a plurality of tool pairs, that is to say a plurality of press stages, an adjusting device and a coupling device are provided for each punch, the coupling devices being connected to one another and to the single motor via gear wheels. One motor is therefore sufficient to adjust several pressure pieces.
  • FIG. 1 shows a horizontal section through a pair of tools 1 of a three-stage forming press, the details of which have been omitted here for the sake of clarity.
  • the pair of tools 1 consists of a stationary die 2 and a press slide 3 which can be moved back and forth in the direction of the double arrow A.
  • a stamp block 4 is attached for each step, in each of which a press stamp 5 is inserted.
  • the ram 5 is supported with its back on a pressure piece 6, which is guided in the press slide 3 in the direction of the double arrow A.
  • the back of the pressure piece 6 is bevelled and sits on a complementary beveled surface of an adjusting wedge 7.
  • This adjusting wedge 7 is guided in the press slide 3 perpendicular to the axis of the press ram 5, the displacement of which due to the inclined surfaces a corresponding displacement of the pressure piece 6 and thus of the ram 5 causes.
  • the displacement of the adjusting wedge 7 is effected by rotating a spindle 8 which is fixedly mounted in the press slide 3. At the end opposite the adjusting wedge 7, this spindle 8 merges into a drum-shaped part 9, which has a clamping sleeve 10 and one with the press slide 3 connected spindle housing 11 is bypass.
  • the drum-shaped part 9 and thus the spindle 8 can be fixed in their respective position by hydraulic pressurization of the clamping sleeve 10.
  • a servomotor 13 and a coupling device 14 are provided, both of which are fixed in place on the forming press frame 15, that is to say do not swing back and forth with the press slide 3.
  • the coupling device 14 has the task of establishing the connection between the servomotor 13 and the spur gear 12.
  • it has a drive pinion 16 which is seated on a stepped pin 17 which is connected in a rotationally fixed manner to a drive sleeve 19 surrounding the pin 17 via a slide spring 18.
  • This drive sleeve 19 is mounted via the roller bearings 20, 21 in a clutch housing 22 and is formed at the end opposite the drive pinion 16 to form a drive gear 23 which meshes with a motor pinion 24 flanged to the servomotor 13.
  • the bolt 17 is surrounded in the interior of the drive sleeve 19 by a compression spring 25, which is supported at one end on the drive sleeve 19 and at the other end on the stepped part of the bolt 17 and in this way strives to pull the bolt 17 into the drive sleeve 19.
  • the drive pinion 16 as shown in FIG. 1, is located outside the engagement area on the spindle 8 seated spur gear 12, so that there is no risk of collision when the press carriage 3 is moved back and forth.
  • the rear of the clutch housing 22 is provided with a housing cover 26, in which an actuating piston 27 resting on the rear of the bolt 17 is guided.
  • This actuating piston 27 is preceded by a pressure chamber 28 which can be acted upon hydraulically or pneumatically. In this way, the actuating piston 27 and thus pin 17 and drive pinion 16 slide 3 can be pushed on the presses.
  • drive pinion 16 and spur gear 12 then engage so that the rotary movement of the servomotor 13 is transmitted to the spindle 8 and the adjusting wedge 7 and the pressure piece 6 are displaced.
  • FIG. 2 shows a side view of the forming press with the three dies 2, 29, 30 and the press slide 3 on which the three punch blocks 4, 31, 32 are seated.
  • the pressure pieces 6, 33, 34 and the majority of the spur gears 12, 35, 36 seated on the spindles, not shown, are drawn in dashed lines drawn drive pinion 16, 41, 42.
  • the drive gears 23, 37, 38 are in engagement with one another, so that for the adjustment of the pressure pieces 6, 33, 34 only one servomotor 13 is required, the motor pinion 24 meshes with the lowest of the three drive gears 23.
  • the servomotor 13 can be connected to a remote control device with which the adjustment and its control can be controlled by a control panel.
