Definitions

  • the invention relates to a forming press with at least one pair of tools, each consisting of a punch and a die, each punch being supported by a pressure piece on the press slide and the pressure piece being displaceable in the direction of movement of the press slide by a linearly displaceable wedge which can be actuated by a motor-driven spindle is.
  • the object of the invention is to facilitate the adjustment of the stamp and to reduce the susceptibility to faults.
  • 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 be carried out by means of an actuating piston which can be pressurized against the action of a spring. With the help of this 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 such that the pinion is fastened to a bolt which is seated in a drive sleeve and is connected to the drive sleeve in a rotationally fixed manner via a sliding 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 remotely controlled 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.
  • a wedge and a spindle as well as a coupling device can be provided for each punch in a forming press with several pairs of tools, that is to say with several press stages, 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.
  • the back of the press ram 5 is supported 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 or 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 causes a corresponding displacement of the pressure piece 6 and thus the punch 5 causes.
  • the shifting of the adjusting wedge 7 is effected by rotating a spindle 8 which is fixedly mounted in the press slide 3.
  • This spindle 8 merges at the end opposite the adjusting wedge 7 into a drum-shaped part 9 which is surrounded by a clamping sleeve 10 and by a spindle housing 11 connected to the press slide 3.
  • 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 or 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. To do this, she points out a drive pinion or pinion 16, which is seated on a stepped pin 17, which is connected in a rotationally fixed manner via a slide spring 18 to a drive sleeve 19 surrounding the pin 17.
  • This drive sleeve 19 is supported 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 or 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 thus 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 of the spur gear 12 seated on the spindle 8, so that there is no risk of collision when the press slide 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 can be pushed onto the press slide 3.
  • 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 most of the spur gears 12, 35, 36 seated on the spindles (not shown) are drawn in dashed lines. They are covered by the drive gears 23, 37, 38 of each coupling device 14, 39, 40 as well as the dashed lines drawn drive pinion 16, 41, 42.
  • the drive gears 23, 37, 38 are in engagement with one another, so that only one servomotor 13 is required for the adjustment of the pressure pieces 6, 33, 34, the motor pinion 24 of which meshes with the lowermost of the three drive gears 23. Otherwise, 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.
