Definitions

  • the subject of the present invention is an assembly for implementing operations, such as cutting, bending, etc. a strip of sheet material, for example a strip of metallic sheet, advancing in successive steps of a particular length to the workpiece, said assembly comprising as many punches as operations to be performed, each punch being mounted in a punch holder opposite a die to form a work station and the various punch holders and dies being mountable respectively in the same sole which can be secured to the upper jaw of a press and in the same frame secured to the lower jaw of said press.
  • each tool comprising, in addition to the punch, the punch holder and the die specific to the operation, a specific carcass mounting on the press and at least one pair of guide columns.
  • the object of the present invention is to reduce the price of the tooling used for strip manufacturing by not making it more specific to the part manufactured but adaptable to the production of different parts, and thus to allow, on the one hand, substantial savings during the production of large series of parts and, on the other hand, strip production of small and medium series.
  • the punch holders can be immobilized in the common sole by penetration into appropriate openings provided in said sole and blocking by means of punch covers, while the dies are immobilizable in suitable cutouts provided in the common frame, the punch holders, the openings, the punch covers, the dies and the cutouts being all of standard dimensions, thanks to which the spacing of the punches from the work stations can be adapted to the particular advancement step for the manufactured part.
  • the point of attack of the worked blank may vary to the left or to the right relative to the center of the work station, or there may be several punches per work station.
  • the assembly according to the invention comprises two categories of constituent elements, namely invariable standardization elements comprising the upper sole, the punch covers, the die holders and the frame, and interchangeable standardized elements comprising the door - punches and dies.
  • the invention is also applicable to recovery tools, for example, for the purpose of bending parts prepared elsewhere.
  • the tool comprises a standardized opening sole for the establishment and blocking of a particular punch and a frame with standardized cutout for the establishment and blocking of a particular corresponding matrix.
  • Figures 3a, 3b, 4a and 4b show the embodiment, also according to the prior art, of a substantially rectangular part extended by two tongues and arched. Again, there is provided a blank cutting tool (Figure 3a) and a bending tool (Figure 4b) completely separate from each other and each comprising their own punch cover 1, their own frame 2 and their own ball columns (not shown).
  • the tool of FIG. 3a cuts the substantially rectangular part 7 from a blank 6 and the tool of FIG. 3b gives it the desired camber.
  • Figures 5 and 6 which illustrate an embodiment of the invention show that unlike the prior art, one does not use, for the manufacture of small and medium series, a succession of complete and isolated tools , but, as in the conventional tape manufacturing technique, a succession of work stations comprising, in a common structure, only the parts of tools ensuring the expected function.
  • the common structure is not specific to a given workpiece but can be used for any parts requiring different advancement steps.
  • the assembly according to the embodiment of the invention comprises a lower frame 8, on which is mounted a die holder 9 having several circular cutouts 10 of same diameter. These cutouts 10 each receive a circular matrix 11 in two parts 11 a and 11 b.
  • the part 11a of the matrix comes to bear on a shoulder 12 defined by the cutout 10 in the die holder 9 and the part 11b of the matrix, which fits into a cutout 13 provided in an elastic blank press 14, rests on part 11 a of matrix, with blank interposition 6 to be worked. It will be understood that the part 11b therefore plays a role of blank blank.
  • the assembly further comprises an upper sole 15 having as many circular openings 16 of the same diameter as the die holder 9 has cutouts 10, which openings are adapted to receive punch holders 17 facing each other. dies 11.
  • Each punch holder 17 is mounted on a punch cover 18 which is blocked in the upper sole 15 at a shoulder 19 provided in the opening 16.
  • the frame 8, the elastic blank holder 14, the upper sole 15 and the punch covers 18 are invariable elements of the structure while the punch holders 17 and the dies 11 are interchangeable .
  • the dimensions of the interchangeable elements and the invariable elements are standardized so that it is possible to mount the interchangeable elements at any position in the assembly.
  • three work stations are provided which are, from left to right, a drilling station, a pre-diverting station and a bending and separation station.
  • the first station comprises two cylindrical punches 20, the second station a pre-diverting punch 21 and the third station a bending punch 22 and a separation punch 23. It is provided, in a manner known per se, of pilots 24 to adjust the advance of the blank 6.
  • the method of fixing the punches in the punch holders has not been shown. It can be produced in any suitable manner, in particular by screws and pins.
  • FIG. 6 shows, at this 3rd station, the method of fixing the blank holder 14 and the matrix 11. It is clear from the comparison between FIGS. 5b and 6b that, in the 2nd work station, the punch 21 does not occupy the same position as the punch 23, this, to adapt the point of attack to the pitch of advancement of the blank and, therefore, to the particular piece.
  • Figure 7 shows a recovery tool which can be used for the bending of the part 7 as coming from the assembly of Figure 6b.
  • the tool is designed according to the same principle as the assemblies in FIGS. 5b and 6b and, here again, the similar parts are designated by the same references.
  • the comparison with the isolated bending tool in FIG. 3b clearly shows the difference in design between the known tool and the new tool.
  • the invention makes it possible to considerably reduce the cost of the tooling used for the manufacture of large series of pieces with the strip and that it allows this strip working technique to be used for small and medium series, the price of tooling no longer needs to be justified by the large number of parts to be manufactured. Finally, it reduces the risk of work accidents since it replaces, for the modification of the functions of a production line, the movement of heavy tools by that of small interchangeable parts.
