Definitions

  • the present invention relates to devices used for mounting folding punches on a press brake.
  • these punches are fixed on the lower edge of the upper deck of such a press, and this opposite a v-shaped matrix, fixed on the upper edge of the lower deck.
  • These punches and dies are removably fixed in place so that they can be replaced by other punches and dies of different profiles, depending on the thickness of the sheets, and the nature of the folds to be produced in a sheet.
  • the punches comprise a heel intended to be engaged in a recess of the edge of the upper deck and to be fixed thereto by means of a number of clamps, distributed lengthwise.
  • British patent GB-A-2 057 047 which describes a device for fixing a punch on the apron of a press, illustrates various variant embodiments where the heel of the punch has different sections.
  • the heel is offset on the side of the punch to release a support area located in the axis of the thrust of the deck.
  • the axis of the thrust is exerted on two lateral support zones formed on the heel of the punch while being symmetrical with respect to the axis of the thrust.
  • the heel of the punch has a support area located above it and in the axis of the thrust.
  • the subject of the present invention is an adapter designed to remain permanently fixed to the apron of a press brake and to be able to receive punches comprising fixing heels of different types, including those of the type provided for the corresponding press. .
  • the adapter according to the invention makes it possible to mount, on the deck of a press brake of a given brand, punches whose fixing heels may or may not correspond to the type provided for this press. It then suffices to change the position of the support wedge provided in the removal of the body of this adapter to transform, in an appropriate manner, the location of the housing provided for the heel for fixing the punch to be mounted in place.
  • Figures 2, 3 and 4 are views in vertical section of this same adapter, these views showing the mounting modes of punches having fixing heels of different types.
  • Figures 5, 6 and 7 are sectional views of another embodiment of the adapter. These views representing the mounting modes of punches comprising fixing heels of different types.
  • the body of the adapter takes the form of a bar 1 extending over the entire length of the lower edge of the upper deck 2 of a press brake.
  • the body of this adapter could also consist of a series of bar sections, distributed one after the other, with a certain interval or not, along the length of the edge of the upper deck 2 of a press.
  • This bar in one piece or formed from a series of successive sections, is intended to be fixed permanently to the edge of the upper deck 2 of a press of a given brand.
  • this bar is arranged to be mounted on a press designed to receive punches 3 comprising a fixing heel 4 of the offset type on the side with a support zone 5 located in the 'XY axis of the folding thrust. Consequently, the upper face of this bar itself carries a heel 6 offset to the side and which is able to be placed inside the lateral recess 7 formed in the lower edge of the upper deck 2 of the corresponding press. , in order to usually receive the heel 4 of the punches 3 provided for this press.
  • the heel 6 of the bar 1 is then fixed in the usual manner inside this recess, that is to say by means of a series of clamps 8 distributed over the entire length and fixed on the edge of the apron 2 using screws 9.
  • FIG. 1 represents one of the three possible types of heels for fixing the bar 1 of this adapter.
  • the shape and arrangement of this heel must vary depending on the type of press on which the present adapter is to be fixed.
  • a series of shims 10 are interposed between the upper face of the bar 1 of the lower face of the apron 2 of the press. These shims are held in place by screws 11. It is therefore sufficient to unscrew these to move these shims in order to very precisely adjust the position of the bearing faces 5. relative to the upper deck 2.
  • the presence of these shims 10 is optional.
  • the bar 1. constituting the body thereof has, at its lower part, a recess 12 open on one of the faces of this bar, usually the face of the latter intended to be placed on the front of the corresponding press.
  • the depth E of this recess is significantly greater than the thickness of the fixing heel 4, 4a and 4b of the three types of punches intended to be mounted on the present adapter.
  • a support wedge 13 is provided, the height of which is equal to that of the recess 12 and the thickness of which corresponds substantially to the difference existing between the depth E of this recess and the thickness of the various types of heels 4, 4a and 4b of the various punches to be mounted on the present adapter.
  • this support wedge 13 is able to be placed inside the recess 12 against the heel of the punch to be fixed in place, either at the bottom of this recess or on the external side.
  • This wedge therefore makes it possible to transform, in an appropriate manner, the location of the housing provided for the heel for fixing the punch to be mounted in place.
  • This support member is retained in place by the screws 14 provided to ensure the tightening of a series of fixing flanges 15 distributed over the entire length of the present adapter. Indeed, before being screwed into the bar 1, the ends of these screws are engaged through bores 16 passing right through the support member 13. Thus the latter can be moved in the transverse direction by sliding on the clamping bolts 14.
  • FIG. 2 illustrates the case where the adapter is used to mount, on the deck 2 of the corresponding press, a punch 3 whose fixing heel 4 is of the offset type on one of the sides.
  • the support wedge 13 is placed in the bottom of the recess 12 so that the support zone 5 of the punch 3 comes to bear against the underside of this wedge. Under these conditions it serves as an intermediate element for the transmission of the pushing force between the punch 3 and the body 1 of the adapter.
  • the lower part of the bar 1 may advantageously include a series of holes 17, distributed over its entire length, and making it possible to engage, inside the recess 12, a pushing tool according to arrow F in order to push the support wedge 13 outwards.
  • the fixing heels 4, 4a and 4b of the different punches comprise a retaining spoiler 18 intended to prevent an accidental fall of these punches during the loosening of the fixing flanges 15. This spoiler 18 is stopped depending on the case either by the flange 15 or by the recesses 21 or 22.
  • FIG. 4 represents the mounting of a punch 3b comprising a central heel 4b with upper support 5b.
  • the body of the adapter obviously remains always fixed on the apron 2 of the press.
  • this support member itself has , at its lower part, a recess 19 open on the side opposite to the front face and intended to receive the fixing heel 4b of the punch 3b.
  • the support wedge 13c serves, as before, as an intermediate element between the punch and the body 1 of the adapter for transmit the folding thrust.
  • FIGS. 5 to 7 show another embodiment of the adapter which is designed to allow the mounting of punches of the three types in question, without there being any need to change the support member placed at the inside of the body recess of this adapter.
  • the support member thus provided is of the type of member 13c already shown in FIG. 4.
  • the recess 12c provided in the body 1c of the corresponding adapter, then has a groove 20 ( Fig. 6 and 7) at the bottom. This is intended to possibly receive the projecting part of the support member 13c, which is located above its recess 19.
  • the body 1c of the adapter which can 'always be consisting of a single bar or a series of bar sections arranged one after the other. has a greater thickness than the body 1 of the adapter shown in FIGS. 1 to 4.
  • FIG. 5 illustrates the method of mounting a punch 3 comprising a fixing heel 4 of the offset type on the side.
  • the support member 13c is then placed in the bottom of the recess 12c of the bar 1c.
  • FIG. 6 it illustrates the mounting of a punch 3a comprising a fixing heel 4a situated in the center and on either side of which lateral support zones 5a are provided. As in the case illustrated in FIG. 3, the mobile support wedge 13c is then placed on the external side.
  • FIG. 7 illustrates the method of mounting a punch 3b whose fixing heel 4b is located in the center and has a bearing surface 5b on the top.
  • the adapter shown in Figures 5 to 7 therefore allows to mount in place either a punch of one of the three types considered 3, 3a and 3b.
  • the punches of one or the other of these types can have any desired section according to the desired folds.
  • the body of the present adapter can be constituted by a bar made in one piece or by a series of bar sections, arranged one after the other with an interval or not.
  • the movable support wedges 13 or 13c may themselves be constituted by a continuous element or a series of fractional elements arranged one after the other. In the latter case each of these elements can be associated with a fixing flange 15 by being carried by the two clamping screws 14 of the considered flange.
  • the adapter according to the invention has the advantage of allowing the user of a press of a given brand to be able to adapt thereon, not only punches specially designed for this press. , but also punches intended for press brakes of different brands. without having to dismantle this adapter.
