Definitions

  • the invention relates to a tool slide unit and its drive-carrying exchangeable plate for punching and bending machines, which can be attached and screwed onto the front of a hollow box with a drive device and which has an upper and a lower bore arrangement, through which the drive shafts of the tool slide units are provided with a pinion protrude through and which has an elongated machining opening located symmetrically between the two bore arrangements in the central region of the removable plate.
  • Such a removable plate is known from DE-A 3200473.
  • the holes are arranged in a circle concentric to the center of the removable plate.
  • the interchangeable plate has proven itself in practice because the interchangeable plate with the tool slide units attached to it can be removed for retrofitting and can be replaced by another previously exchangeable interchangeable plate.
  • the known interchangeable plate is only suitable for hollow boxes that have a central drive gear.
  • the tool slide units can also be arranged radially but parallel to one another. In the latter case, they have to be of different lengths. However, the space for accommodating the units is limited.
  • the surface of the removable plate is only partially used.
  • the object of the invention is to design the known interchangeable plate while maintaining its advantages such that tool slide units of the same length can be used and more units can be installed with the same area of the interchangeable plate.
  • each drive wheel has a hollow toothing in which the pinion of the drive shaft of the tool slide unit engages in terms of drive, and each drive wheel is aligned with a bore in the mounted interchangeable plate and is connected to a coaxial pulley which is wrapped by two belts lying next to one another , which each wrap around one of the two adjacent pulleys.
  • the removable plate which can be used up to the opposite edges, it can have a smaller format than the generic removable plate. This facilitates transportation and assembly. Less space is required for temporary storage in the warehouse. Since all tool slide units are of the same size, upgrading is simplified and storage costs are reduced. This has a particularly favorable effect in the case of exchangeable plates, because - due to the system - a large number is required.
  • the removable plate 10 seen in FIG. 1 forms the side wall of a laterally open hollow box 12 (FIG. 3) of the same format.
  • the exchangeable plate 10 is rectangular and has an upper row of bores 14 and a lower row of bores 16, two bores 14, 16 of the upper and lower rows being aligned vertically. Below each bore 14 or above each bore 16 there are a number of mounting holes 18 for fastening a tool slide unit 20 in each case. Between the two mounting surfaces 22, 24, which have mounting holes 18, for the slide assemblies 20 there is a recessed, rectangular area 26, which extends over the entire length of the plate 10 and which represents a sliding guide for square workpiece carriers 28 (FIG. 6).
  • An elongated machining opening 34 extends parallel to the center between the two rows of holes 14, 16 this over almost the entire length of the removable plate 10, but ends at a distance from the vertical edges of the removable plate, so that the upper and lower half of the removable plate 10 form a coherent stable unit.
  • the processing opening 34 serves to receive the drives for workpiece carriers, center punches, calibration mandrels, ejectors and the like.
  • the carriage assemblies 20 are of conventional design and therefore do not need to be described in detail. From the base plate 36 of the carriage assembly 20, a bearing socket 38 protrudes on the back, in which the drive shaft 40 of the assembly 20, which carries a gear 42, is mounted.
  • the hollow box 12 has an upper bearing beam 44 and a corresponding lower bearing beam, on each of which a number of drive members 46 equal to the number of bores 14, 16 are rotatably mounted.
  • Each drive member 46 consists of a toothed belt pulley 48 and two drive wheels 50 with hollow teeth screwed on both sides, into which the gear wheels 42 of the units 20 are inserted in terms of drive.
  • the toothed belt pulley 48 is wrapped by two toothed belts 52, 54.
  • the toothed belt 52 connects the belt pulley 48 to the belt pulley of the unit 46 adjacent on one side, while the other belt 54 connects to the drive element 46 on the other side.
  • the toothed belts 52, 54 thus wrap around adjacent pulleys with a large wrap angle of 180 °, as a result of which large driving forces can be transmitted.
  • the first pulley 48 of both rows of pulleys is wrapped by a drive belt 56, which is in drive engagement with a pulley 58 of a transmission, which can be coupled to a motor drive.
  • the free areas of the last pulley 48 of the two rows of pulleys can be connected by a synchronizing belt 60, so that a closed gear train results.
  • FIGS. 4 and 5 show an interchangeable plate 10 with a mounted slide assembly 20 in view and in section.
  • FIG. 6 shows an interchangeable plate 11 with assembled slide assemblies 20, which differs from the interchangeable plate 10 in that the machining opening consists of a number of bores 35 separated from one another by vertical webs, the diameters of which are larger than those of the bores 14, 16 and are aligned vertically with them are.
  • a workpiece carrier 28 is assigned to each bore 35.
  • Figure 7 shows a removable plate 10, which consists of an upper half 10a and a lower half 10b.
  • Each of the two plate halves 10a, 10b comprises a full row of bores 14, 16 and half of the central recess 34.
  • the two plate halves 10a, 10b have a common horizontal central dividing line 10c.
  • the exchangeable plate 10 according to FIG. 8 consists of the two plate halves 10d, 10e, each of which has half a set of upper and lower rows of holes and which meet along the dividing line 10f, which runs at right angles to the rows of holes.
  • the box girder 12 consists only of the upper bearing beam 44 and an identical lower bearing beam, both of which are connected to one another by end walls to form a rigid housing which is closed by removable side walls which separate the exchangeable plates 10; 11 form.
  • Each beam consists of two halves that meet in the middle of the bulkhead. In the bearing beam there are bearing holes into which the bearings for the drive members 46 and these are inserted.
