Definitions

  • the invention relates to an upwardly open receptacle into which a flat, disk-shaped tool part of an at least two-part tool, in particular a die of a punching machine, is inserted in a lowering manner.
  • an at least two-part tool is used, which comprises at least one die and a punch. The latter is inserted into an upper tool holder, while the die is inserted into a lower holder.
  • a tight fit between the outer contour of the die and the receiving recess is necessary.
  • the outer contour of the natrize is often circular, but the circle can be interrupted by protrusions or notches or the like.
  • the cross-section of the receiving recess is constant from its free upper edge to the bottom, ie there is no provision for an insertion bevel or chamfer in the level.
  • This is mainly due to the fact that nan attaches importance to a closed support surface for the workpiece to be machined, for example a sheet metal plate, on the die and the surrounding area of the receptacle. On the other hand, this makes it difficult to insert the die into the receptacle, because even a slight tilting makes it impossible to lower or insert it in the tight fit.
  • an "upward open receptacle” means a receptacle in which the tool part or. the die can only be moved from top to bottom in the working direction of the punch or in the axial direction of the tool.
  • a receptacle is also open at the bottom, but this opening is smaller and has nothing to do with the mounting of the natrize, but rather enables the punched part to pass downward.
  • the recording itself is either directly on the machine table or the like. the Punching machine, or on a machine part, in particular a ring-shaped machine part used in this machine table. However, the latter is of minor importance in view of the present invention.
  • the object of the invention is now seen in designing a punching machine in the area of the lower receptacle for the lower part of an at least two-part tool such that the lower tool part, in particular a die, can be inserted more easily and more quickly.
  • the punching machine is designed in the region of the upwardly open receptacle according to the preamble of claim 1 and the die in accordance with the characterizing part of this claim.
  • the die is brought into the flute between the upper and lower receptacle transversely to the working direction of the punch stub, for example, is moved along the upward-facing surface of the receptacle. It is held so that its counter surface hurries ahead and is moved as precisely as possible against the cross stop. As soon as the counter surface of the die has reached the cross stop, the die is located exactly above the receiving recess.
  • the longitudinal guide should protrude so far over the upper edge of the receiving recess that the die is guided from the start, in particular over its entire length (sodium pickle).
  • care must now be taken to ensure that the upper end of the longitudinal guide, with the die lowered, that is to say completely pushed into the receiving recess, does not protrude beyond the upper ends thereof. This ensures that the workpiece resting on the die, for example a metal sheet, can be displaced in any way within the XY plane without being hindered by the longitudinal guide and, of course, also without being hindered by the transverse stop.
  • a preferred embodiment of the invention provides that the transverse stop and the longitudinal guide are arranged on a displaceable Elerent, which when the die is struck occupies a raised and, when the die is lowered, a lower displacement position.
  • the displaceable element is brought into its raised position, so that both the transverse stop and the longitudinal guide assume the position required for the guided insertion.
  • the longitudinal guide is preferably at least twice as long as the die.
  • the stop counter surface of the die preferably extends over the entire die height. fold the insertion of the die, you can also slide the sliding element in the same direction down. It is basically without disadvantage if both the die and the displaceable element are lowered together.
  • the stop element is designed as a displaceable and lockable bolt, the partial surface of the jacket assigned to the receiving recess of which forms or receives the transverse stop and the longitudinal guide.
  • the bolt preferably has a circular cross-section, but other types of cross-sections can also be used and can be quite advantageous.
  • the transverse stop and the longitudinal guide are, as it were, attached on the inside, as a result of which the cross section of the stop element does not form a complete circular area. In both cases, the transverse stop advantageously also forms the longitudinal guide.
  • the stop counter surface is formed by a longitudinal groove-like recess in the natrize.
  • the longitudinal groove-like recess it is not necessary for the longitudinal groove-like recess to be delimited by an arc; other cross-sectional shapes, in particular angular cross-sections, can also be used.
  • the bolt is of a particularly simple shape and is therefore easy to manufacture. The same also applies to the hole in which the bolt is moved from its working position to a lowered sliding position and vice versa.
  • the bolt can be locked at least in its lower displacement position by means of a locking device.
  • the locking can be carried out, for example, in such a way that the die is at the same time secured against lifting out, for example by friction.
  • the locking device for example a set screw, can act on the latter along the longitudinal axis of the bolt and thereby press it firmly against the entire surface of the die, which then creates the pressure that can be used for securing at this point.
  • Another preferred embodiment is by an intermediate the longitudinal guides and the die are connected, in the lowering direction displaceably mounted intermediate member, on which the transverse stop and a driving surface pointing against the direction of insertion are located for the natrize.
  • the die is not lowered directly here, but with the interposition of the intermediate member along the longitudinal guide, that is, inserted into the receiving recess.
  • the striking of the die introduced in the transverse direction takes place at the intermediate link, ie the transverse stop and the longitudinal guide are two separate surfaces in this variant, whereas in the embodiment described above they can be formed by one and the same surface.
  • the intermediate link is raised, its driving surface is approximately at the level of the upward-facing surface of the receptacle. You can thus move the die along this surface against the cross stop.
  • the die is also on or possibly slightly above the driving surface.
  • Fs is more advantageous if the height of the intermediate link is selected so that the die rests on the driving surface when it is slightly above the receiving recess. This means that the pick-up area can also be slightly above the surface of the tool holder.
  • the intermediate member has an essentially bolt-like shape and the longitudinal guide is a bore of the tool holder corresponding to the roller cross section.
  • the hole axis runs parallel to the die axis and thus also parallel to the working direction of the punch. So that the driving surface and the cross stop always assume a correct assignment compared to the tool receiving, it is advantageous if the intermediate link is displaceable but non-rotatably supported. If the tool holder is in a removable machine part, the bearing hole for the intermediate link can also be provided therein.
  • the cross sections of the receiving recess and the Länqs entry overlap and the intermediate member to form the transverse stop and the driving surface has an opening at its upper end, the base of which approximately corresponds to the overlap surface and the height of which approximately corresponds to the die thickness.
  • This recess can be easily made, for example, with the help of a roller-type milling cutter or a disk milling cutter.
  • Fine development of the invention provides that the intermediate member can be lowered against the resistance of a return spring. If you hold the inserted die firmly, this also causes the pontic to be held down continuously. Of course, lifting of the inserted die is prevented by holding the inserted intermediate member in a suitable manner.
  • the force of the spring can also be used, at least in a supportive manner, to lift the die out of the receiving recess. Otherwise, the rolling mentioned in claim 3 can be slidably supported against the resistance of a return spring.
  • the intermediate member can be locked in a very advantageous manner, at least in its lower displacement position, by means of a holding device, which can be, for example, a screw.
  • a tool holder 1 of a punching machine which can be made in one piece with the machine table of the latter or manufactured separately and inserted into the machine table, has a receiving recess 2 for inserting a die 3, in particular flush, in the direction of the arrow 4.
  • the die is the lower part of at least one two-part punching tool comprising at least one punch.
  • the receiving recess is circular in shape and, according to FIG. 2, its depth corresponds to the height or thickness of the die 3.
  • the receptacle is only open at the top, which is why the die has been aligned exactly in the longitudinal direction of the receiving recess after prior alignment Tool axis 5 must be inserted. Even if the natrize is slightly tilted, it is not possible to push it in because the fit is relatively tight.
  • a cuer stop 6 is provided against which a stop counter surface 7 of the die can be brought into contact. Niongs follows that the die is first brought in the direction of arrow 8 over the receiving recess 2 until the two surfaces mentioned abut each other. Subsequently, a guided lowering takes place with the aid of a longitudinal guide 9.
  • the transverse stop and the longitudinal guide 9 are locally separated from one another.
  • an intermediate member 10 is connected between the longitudinal guide 9 and the die 3, on which the transverse stop 6 is located, and which is also displaceably mounted in the direction of arrow 4 in the tool holder or at least displaceably in the area thereof .
  • a nit-taking surface 11 is provided on this intermediate member, which faces counter to the insertion direction 4 and on which the die introduced in the direction of arrow 8 rests before insertion into the receiving recess 2.
  • the intermediate member 10 has an essentially bolt-shaped shape and accordingly the longitudinal guide 9 is a pipe in the receptacle 1, the cross section of which corresponds to that of the intermediate member.
  • the intermediate link is, however, provided on about half its length with a central blind hole 12, which receives a screw pressure fecer 13, which the intermediate limb in its raised position shown in Fig. 1 holds.
  • the intermediate member is brought via the die 3 against the resistance of the helical compression spring 13 into the displacement end position shown in FIG. 2, in which the die has also reached its final assembly position.
  • This final assembly position of the intermediate link and indirectly via this also of the die can be fixed and secured with Nilfe a holding device 14, in particular a screw.
  • the die 3 carries on its outer surface a strip-shaped extension 15 which engages in a longitudinal portion 16 of the intermediate member 10.
  • the longitudinal groove is located at the inner end of a recess 17 at the upper end of the intermediate member 10, and it extends in the same direction as the strip-shaped extension 15, in the direction of the slide 4. In this direction, the height of the recess 17 and the longitudinal groove 16 is equal to the height or thickness of the die 3.
  • the cross-sectional shape of the recess 17 corresponds to the overlap of the cross-sections of the receiving recess 2 and the longitudinal guide 9. Each embodiment is a circular cross-section.
  • the natrize 3 be quickly and securely aligned with respect to the receiving recess 2 in the direction of the X axis 18, but also in the direction of the Y. -Axis 19.
  • the two side flanks 20 and 21 namely form side stops for the Die 3.
  • the transverse stop 22 and the longitudinal groove 23 are arranged on a pole 24 that can be displaced in the lowering direction 4, more precisely, formed by its outer jacket.
  • the stop counter surface is designated by 25 and it consists of a longitudinal groove-like recess 26 incorporated into the edge region of the die 3.
  • the pole 24 is displaceable in a bore 27 of the tool holder 1 in the sense of the double arrow 28. It is a continuous hole, so that the Polzen can be transferred from below by an actuator or in any other way to a raised position.
  • the transverse stop 22 formed by the upper bolt end and the longitudinal guide 23 formed by the same bolt surface are then located above the upper surface 29 of the tool holder 1.
  • the bolt looks at least by an amount corresponding to the thickness or height of the die 3 through its bore 27 out at the top. It can be held in this position by friction. The lowering of the bolt is achieved either by taking it over the die 3 or by moving it separately after the die 3 has been pushed in completely.
  • the inner contour of the die can be shaped in any manner, for example, breisrung according to FIG. 3 or square according to FIG. 5.
