Definitions

  • the invention relates to a punch press with a press housing, at least one plunger, a punching space in which a strip running plane of a respective, to be processed in the tape feed direction through the punching space to be processed band is fixed, with a drive device which is connected to an assembly of toggle units, the are arranged in the tape feed direction on both sides of the drive device.
  • stamping presses In modern stamping technology, development is moving towards the complete processing of a raw material, that is, a complete non-cutting production of a product. This means that a punch press is formed into a complete production center. In addition to the usual cutting and forming (bending) operations, stamping presses increasingly carry out assembly and joining work, they are welded, riveted and threads are also formed. After each processing step of a strip to be processed, the same is advanced in the punch press by a predetermined distance. Furthermore, more and more measuring systems are used for quality assurance during the ongoing work process. This means that the length of the tool installation space, ie the punching space, will be the longer the more individual work steps in the punch press are carried out. Consequently, ever longer tool installation spaces are required.
  • the invention aims to remedy this situation.
  • the object of the invention is to provide a punching machine, in which the power transmission takes place with an arrangement of toggle units, which has a long tool installation space, but allows high engine speeds, requires no increased energy and does not cause excessive dynamic mass forces.
  • the punching machine according to the invention contains at least two toggle lever units on at least one side of its drive device. All toggle units of the punch press are drive-connected with at least one ram.
  • the punch press of the illustrated embodiment has an eccentric shaft 1.
  • This eccentric shaft 1 is driven by a drive motor 51 via a belt drive 52 and a clutch brake device 2.
  • Such coupling brake devices for stamping presses are well known, so that a detailed description is unnecessary.
  • the brake disk 41 and the friction linings 49, 50 are shown purely illustratively by the clutch brake device 2.
  • the eccentric shaft 1 has eccentric sections 3, 4a and 4b.
  • a connecting rod 6 is mounted on the eccentric section 3, and a forked connecting rod 5 is mounted on the eccentric sections 4a, 4b.
  • a forked connecting rod 5 is mounted on the eccentric sections 4a, 4b.
  • In the eccentric sections 3, 4a and 4b also against each other rotatable bushes for stroke adjustment of the ram of the punch press may be present, as is the case with various known stamping presses.
  • the connecting rod 5 is articulated via a hinge pin 7 to a connecting plate 9a, 9b, and the connecting rod 6 is articulated via a Anlenkbolzen 8 to a connecting plate 10a, 10b.
  • the connecting plate 9a, 9b is articulated via a first pin 11 to the first toggle lever core 15a, 15b. Further, the connecting plate 9a, 9b is articulated via a second pin 12 to the second toggle lever core 16a, 16b.
  • the connecting strap 10a, 10b is articulated via a third bolt 13 to the toggle lever core 17a, 17b. Finally, the connecting lug 10a, 10b is further articulated via a fourth pin 14 to the toggle lever core 18a, 18b.
  • the respective upper Kniehebellenker 15a, 16a, 17a and 18a are supported via eccentric shafts 19, 20, 21 and 22 in the housing 23 of the punch press.
  • the respective lower Kniehebellenker 15b, 16b, 17b and 18b are articulated via bolts 24, 25, 26 and 27 to pressure columns 28, 29, 30 and 31 respectively.
  • the bolts 24, 25, 26 and 27 are with their end portions, in the figure 2, for example, the end portions 25 a, 25 b drawn, mounted in sliding blocks, in the figure 1 generally by the reference numerals 32, 33, 34 and 35 and in 3 are generally identified by the reference numerals 32, 33.
  • the respective two sliding blocks of a bolt are shown, so the sliding blocks 33, 33a at the two ends of the bolt 25.
  • the sliding blocks 32, 33, 34, and 35 are supported on the housing 23 via grooves. These grooves are generally identified by the reference numerals 36 and 53 in FIG. 3, and correspondingly in the sectional view of FIG. 2 by 36a and 36b.
  • the pressure columns 28 and 29 connected to the lower bellcrank core 51b and 16b are connected via bolts 54 and 55 to a plunger 56, and the pressure columns 30 and 31 are connected to a plunger 57.
  • all four pressure columns 28, 29, 30 and 31 may also be connected only to a single plunger, or each of the pressure columns could be connected to a separate plunger.
  • the plunger 56 is fixedly connected to two downwardly projecting guide columns 58, 59.
  • the guide columns 58, 59 are guided in the belt running plane 60 in guides 61, 62.
  • the plunger 57 is fixedly connected to guide columns 63, 64 and guided in guides 65, 66.
  • This guide arrangement is described in detail in CH-A-568 848 and US-A-3 998 498, respectively, and reference is made to these documents for the sake of disclosure.
  • the plungers 56, 57 additionally contain a further, ie third guide 67 or 68, which is arranged above the strip running plane 60. Further guide columns 69, 70 fixedly connected to the press housing 23 protrude into these third guides 67 and 68, respectively.
  • the guides 67, 68 have sliding surfaces 71 (FIG. 4), (see the documents cited above), which are in the longitudinal direction of the punch press. ie in tape feed direction, run.
  • the guides 67, 68 thus prevent a deflection of the plunger 56, 57 in the transverse direction of the punch press, but allow due to the sliding surfaces 71, a thermal expansion of the plunger 56, 57 to brace without any ram guides the plunger 56, 57.
  • clamping plate of the punch press are identified by the reference numeral 72 and the base plate by the reference numeral 73.
  • the pressure columns 28, 29 are deformed differently elastically.
  • the plunger 56 assumes a skew, as indicated in Fig. 3 with the distance S, wherein the (exaggerated drawn) inclination of the plunger 56 is shown by the dashed line T.
  • the elastic deformation and change in position of the pressure column 29 are represented by the dashed line U and corresponding to the pressure column 28 by the dashed line V.
  • the inclination of the guide post 58 is shown by the dashed line W.
  • the tilting point K of the plunger 56 remains on the strip running plane 60. This means that the plunger 56 or the tool 74 (upper tool) connected to it in the strip running plane 60 does not deflects.
  • the guide 67 or its running surfaces 71 (FIG. 4) permit a corresponding displacement.
  • the seals 75, 76 between the press housing 23 and the pressure columns 28, 29 are movable seals which prevent oil from the closed press housing 23 in the working space and prevent the tape to be processed and the tools even with an inclined position of the plunger 56.
  • the plunger 56 is connected via the pressure columns 28, 29 and the knee joint levers 15a, 15b and 16a, 16b with the eccentric shafts 19 and 20 in combination, which, as described above, with a common drive, the servo motor 42 in connection. Accordingly, the stutteror 42 in connection.
  • the plunger 57 is connected via the pressure columns 30, 31 and the knee joint lever 17a, 17b between 18a, 18b to the eccentric shafts 21 and 20, which in turn communicate with the servomotor 41. It can thus be seen that the elevations of the two plungers 56 and 57 are independently adjustable. Obviously, the servomotors can also be operated synchronously, so that the height bearings of the plungers 56 and 57 are also synchronously adjustable.
