Definitions
- the invention relates to a method and a device for producing and / or processing parts, in particular for producing stamped parts, having at least one tool which can be placed under pressure and / or force according to the preamble of method claim 1 and device claim 4, respectively.
- the present invention relates to all machines which have a tool with which parts are to be manufactured or processed under pressure.
- the processing machines may be thermoforming devices or the like.
- punching machines in which stamped parts are produced in a tool, which consists of an upper and a lower tool part, between which a strip of material is clamped.
- Corresponding cutting or forming elements then press on the material and separate it out or reshape it.
- a corresponding fine cutting device is for example in the DE 35 76 129 D1 shown.
- a fineblanking tool can be found in the DE 197 51 238 A1 ,
- the serrated or counter-pressure cylinders are arranged centrally in the compact or plunger.
- Einlagering or a mold plate which is arranged centrally above the printing cylinder.
- the disadvantage of this central impression cylinder arrangement is that the force transmission can not be matched to the tool needs. Furthermore, there is no way to divide the work stages, if different print or Lift heights are required. This refers to both the number of force-transmitting elements, as well as their size and position. Due to this rigid arrangement of the printing cylinders, the use of tools with an eccentric load leads to tilting or tilting of the printing plate. In order to circumvent this weakness, sliding pressure pads have been used, but have the great disadvantage that the setup effort requires an unacceptable extent and the press body and the press ram are weakened by the large openings accordingly in their structure and the cushion dimensions are not changed arbitrarily can be.
- the present invention has for its object to develop a method and apparatus of the type mentioned above, which allow a free and flexible arrangement and control of the force-transmitting elements, so that in the end punched parts of any size and geometry can be manufactured.
- the basic idea of the present invention is a field of force-transmitting elements in which they can be made in any number, in a variable arrangement and transmission surface.
- the forces themselves transmitted by the force-transmitting elements can be hydraulic, pneumatic, spring force, mechanical or electromotive be generated.
- the force-transmitting elements can be adapted in size and number according to the respective tool concept.
- the individual force-transmitting elements can be independent of each other both force as well as way dependent and be controlled and / or regulated depending on the requirements of the tool.
- a corresponding device consists of several individual force-transmitting machine elements (cylinders, springs), which are arranged distributed in an arbitrary grid over the entire table or tappet surface of the press.
- the individual elements / stations can be controlled independently of one another or in any desired arrangement in a pressure-dependent and / or path-dependent and / or force-dependent manner. Over different length bridge bars or arbitrarily shaped fittings in the tool change plates or in the tool, the individual stations / elements can be connected in any number and arrangement. In this way, several independent force transmission fields can be provided in different length / extent and force.
- cross-bridge bars are provided in the tool. (or fittings) arranged. These cross bridges are formed according to the individual tool stages and part of the tool.
- a tool 1 arranged underneath a removable plate 2 and arranged under the removable plate 2 table 3.
- the replacement plate 2 is preferably connected to the table 3 via T-strips, which engage at least partially in T-grooves 4. How this happens is, for example, in the DE 36 62 351 D shown.
- the pressure ram 5 surrounds a ring 36 in the position of use.
- a plurality of pressure force elements 5 are arranged, above each of which a pressure pin 6 is seated, which is guided and held in the removable plate 2.
- a support spring 9 which holds the pressure pin 6 in the supporting position.
- the pressure pins 6 support a transverse bridge 10, so that there is a clearance 11 between the transverse bridge 10 and the removable plate 2 by forming a distance a.
- This support position of the pressure bolt 6 allows a smooth change of the removable plate 2 together with the cross-bridge bar 10, since the pressure pin 6 does not hang down from the removable plate 2.
- the transverse bridge 10 is equipped with a sprung ball pressure screw 13. This ball pressure screw 13 engages in a groove 14 of the removable plate and thus fixes the cross-bridge 10th
- the length of the transverse bridges 10 are designed according to the tool requirements so that they cover two or more pressure pin 6.
- a tray 16 On the transverse bridge 10 is a frame 15.
- a tray 16 In this frame 15, a tray 16 can be seen, in which a pressure pin bridge 17 is slidably guided.
- the pressure pin bridge 17 is supported by a support mushroom 18 against the transverse bridge 10, wherein the support mushroom 18 is connected by means of a bolt 19 with the pressure pin bridge 17.
- the support mushroom 18 causes the pressure pin bridge 17 from the surface of the removable plate 2 also maintains a distance a. This distance also corresponds to the distance a of the transverse bridge 10 in the free space 11 of the removable disk 2. It defines the maximum Druckkissenhub.
- the shape of the tray 16 and the pressure pin bridge 17 depends on the particular tool needs. Like the transverse bridge, the pressure pin bridge does not need to be a straight fitting, but any shaped parts are conceivable, for example oval, round or at an angle to one another. Corresponding embodiments then also have the compartments 16 and free spaces 11.
- FIG. 1 for the pressure pin bridge 17 a retractor 20 recognizable.
- This has a bolt 21 which is screwed into the pressure pin 17 bridge.
- the head 22 is supported via a coil spring 24 against a lower step 25 of this stepped bore 23.
- the pressure pin bridge 17 is pulled up with the support mushrooms 18, and the lower edge of the support mushrooms 18 closes flush with the lower edge of the frame 15 and the tool base 1 from.
- the tool base 1 can be easily removed and inserted for tool change.
- a tool element 26 which is an ejector in the present embodiment. From this ejector an ejector ring 27 is shown, which rests on a pressure pin 28. About this pressure pin 28, the ejector 27 can be pressed against the pressure pin 17 bridge. By a coil spring 29, it is pushed back into the starting position.
- the pressure pin 28 passes through a base plate 30, which rests on the frame 15.
- This base plate 30 is connected via a height compensation 31 with a die 32, which is done by a corresponding bolt 33.
- a serration 34 is recognizable for fine cutting.
- a fine cutting device is used, as for example in the DE 35 76 129 A is described.
- the corresponding tool consists of two mold halves, namely an upper and a lower mold half, the device according to the invention can be used in both tool halves application, but within the scope of the invention is also that the inventive device is used only in a tool part.
- the two tool halves are brought together, with the sheet metal from which the part is cut out should, between the two tool halves is arranged.
- the die 32 cooperates with a counter-element, wherein a significant pressure / force is exerted on the die 32 and also on the tool element 26.
- this pressure / force on the height compensation 31 and the base plate 30 and the frame 15 is transmitted to the or the cross member 10, which in turn forces (eg, tilting force or unequal forces) thereby capture that the pressure pin 6 of the hydraulic cylinder 5 yield accordingly ,
- This yielding takes place in the region of the free space 11 by reducing the distance a between the transverse bridge 10 and the removable plate 2.
- the number and arrangement of the pressure pins 6 and the pressure elements 5 can be assigned to the individual tool work stations via the transverse bridges 10.
- the push pin bridges 17 can then be adapted to the requirements of each workstation.
- a special embodiment is additionally provided.
- it is received in the plunger 12 in a hydraulic cylinder.
- three pistons are seated on it, each piston having its own pressure chamber, which can be charged with a pressure medium.
- a force on the pressure force element 5 is substantially increased, which counteracts the immersion of the pressure bolt 6.
