Definitions

  • the present invention relates to a punch press with a frame, a drive, a ram device driven by the drive and a base plate device.
  • a punch press according to the preamble of claim 1 has become known from EP-A-0 281 777.
  • This has two tool carriers, or ram devices and base plate devices for processing two sheet metal strips advanced at right angles to one another, the stamped products produced therefrom being connected to one another in one of the ram and base plate devices.
  • the individual ram and base plate devices are not subdivided to relieve the pressure on the entire punch press and cannot accommodate larger, off-center loads.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of creating a punch press in which the ram device is divided into a number of ram sections carried independently of one another in the direction of travel of a workpiece and the base plate device is equally divided into mutually independently supported base plate sections .
  • the advantages achieved by the invention can essentially be seen in the fact that the ram and the base plate are divided for a long time and narrow tools can be used. Furthermore, in order to complete a product in the punch press in a single pass, the UT positions of the individual rams can be set out of phase, so that the total load on the machine is reduced. The division into individual sections also results in smaller oscillating masses, because obviously the mass balance is also divided in sections. A very high dynamic stability is thus achieved.
  • the punch press has a drive which is constructed in a known manner and which contains an electric motor 16 which drives the V-belt pulley 26 via a V-belt 17.
  • the V-belt 17 and the V-belt pulley 26 are arranged in a housing cover 27.
  • the V-belt pulley 26 is drive-connected to the flywheel 18 of the punch press.
  • the clutch 19 and the brake 20 are arranged in this flywheel 18, as indicated in FIG. 2, the associated power transmission disks being identified in FIG. 2 by the reference numbers 19 and 20.
  • This clutch braking device 19, 20 is arranged together with the flywheel 18 in a housing 21.
  • This housing 21 is equipped with support columns 25, via which support columns 25 the housing 21 on the respective floor 24, for example Workshop is supported.
  • a first frame section 11 of the overall frame of the punch press is rigidly screwed onto the housing 21 by, for example, screw bolts 28.
  • a shaft section 14, which is designed as an eccentric shaft, is mounted in the frame section 11 via bearings 29, 30.
  • This shaft section 14 is connected via a coupling 31 to the output shaft section 32 of the clutch braking device 19, 20.
  • This coupling 31 is designed such that rotational forces can be transmitted from the output shaft section 32 to the shaft section 14 in a driving manner, but relative axial and radial movements, including those which occur due to bending of the shaft section 14, can be absorbed by this coupling 31.
  • Couplings which are only designed to be torsionally rigid are, for example, Oldham couplings which are generally known.
  • the shaft section 14 is designed as an eccentric shaft and drives the two connecting rods 7, 8.
  • the mass force compensation device 9, 10 is mounted on the central eccentric part of this shaft section 14.
  • the compensation unit 9 for compensating the rotating mass forces and the compensation unit 10 for compensating the oscillating mass forces are generally drawn in the figures.
  • the mass balance device, including the shaft section 14, shown here is disclosed in detail in US-A-4,757,734, so that a detailed description thereof is not necessary.
  • differently designed mass force compensation devices can also be arranged.
  • This version also shows two connecting rods 7, 8. It is obvious to the person skilled in the art that drives with only one connecting rod or then with more than two connecting rods according to known designs can also be present.
  • the two connecting rods 7, 8 shown are via a ram height adjustment device 33 with the ram, ie in the punch press designed according to the invention connected to a plunger section 1.
  • the ram height adjustment device 33 indicated in the illustrated embodiment is known, so that a detailed description is not necessary.
  • a base plate section 4 is arranged under the plunger section 1. This base plate section 4 is suspended directly on the frame section 11, so that it or the entire section of the punch press is free of soil.
  • the tappet section 1 is guided over tappet guides 34, in the illustrated embodiment over four guide columns (see also FIG. 5). These tappet guides can be designed, for example, like those which are disclosed in DE-A-38 13 235, so that no detailed explanation of these tappet guides 34 is necessary here either.
  • FIGS. 1 and 2 the structural parts of the punch press, which are arranged in the frame section 11, are present several times, here three times.
  • the ram device of this punch press has three ram sections 1, 2, 3 with the associated mass force compensation device and ram height adjustment device.
  • the base plate device of the punch press is divided into three base plate sections 4, 5, 6.
  • three frame sections 11, 12, 13 are also present.
  • the shaft train driven by the drive is accordingly divided into several shaft sections, the shaft sections 14, 15 being shown in the drawings.
  • the individual shaft sections are also connected to one another with the Oldham coupling described above or a coupling similar to this, by means of which only the rotating drive forces are transmitted, axial and radial displacements and deflections of the individual shaft sections not being transferable to the respectively adjacent ones.
  • the punch press thus has three modular work units, which complement one another, do not influence each other in operation in any way and where the stroke, bottom position and ram height can be set completely independently of each other.
  • the punch press further has a carrier section 22, which is connected to the rightmost frame section 13.
  • This support section 22 has support columns 25, via which it and thus the punch press are supported on a respective bottom surface 24.
  • feed devices 36 Only for the sake of completeness are two feed devices 36 indicated in FIG. 1. Since the plunger device or base plate device, which consists of several sections, apparently processes or processes a considerable length of a strip-shaped workpiece per stroke of the punch press, a feed device 36 is present both at the entry and at the exit of the punch press. These feed devices can also be designed in accordance with known designs, for example the one disclosed in European patent application EP-A-0 366 108.
  • the punch press shown is particularly suitable for extremely long, narrow tools with large eccentric loads. Since such tools can now also be used in follow-up tools which are divided into individual sections, there are no mutual adverse influences with regard to the precision in the case of the often occurring off-center loads. In particular, insertion and assembly work can now be carried out with greater precision. It has already been noted that the deflection of the shaft sections or eccentric shafts or possibly crankshafts cannot mutually influence one another as a result of the connection between the individual shaft sections which is torsionally rigid only in terms of drive. Because each of the three press sections has a self-locking Contains frame section, a mutual influence by different punching loads or frame expansions is excluded.
  • a plunger section can be loaded with the full punching force without the neighboring section being damaged by e.g. Bends or vibrations can be negatively affected.
  • the individual frame sections obviously also have smaller dimensions in comparison with known stamping presses, with the result that a smaller frame suspension results from the punching forces due to the now obviously smaller bending lengths of the ram and base plate.
  • a smaller distance between the belt running height and the longitudinal axis of the shaft train, the crankshaft is obviously also possible. Because there is a larger number of smaller bearings due to the subdivision into sections, less energy is required in operation and, in particular, there is a smaller total bearing play. It should also be noted that, due to the subdivision into individual sections, thermal expansions can be kept smaller and the ram guidance overall can obviously be carried out more precisely.
  • the punch press is only supported on the one hand in the housing of the drive and on the other hand in a separate carrier section, one remains Large free space below the individual base plate sections for removing punched parts. Furthermore, in comparison with punch presses which are designed according to the prior art, the height position of the base plate section and also the operating elements (height adjustment) can be kept lower for the same work, so that the worker remains easily accessible, so that it is not necessary is to provide pits under the base plates or, on the other hand, catwalks for access to individual operating elements.
