Abstract

The invention relates to a device which makes it possible to fix elements such as punches, the section or material of which does not allow the implantation of screws capable of securing them. It consists of two complementary wedges 1 and 2 forming a right parallelepiped contained in a housing b contiguous to the housing a which receives the punch to be fixed 4, and at least one screw 5 capable of driving the movable wedge 1 along its inclined face, causing thus blocking the punch 4 by pinching. This device according to variants is suitable for fixing many punches or other elements.

DEVICE FOR ATTACHING OUT1LS ELBMBNTS

DB PRESS IN THEIR SUPPORT.

  The present invention oonoerne a device for fixing

  of punch and other elements in the cutting tools,

  stuffing, awning and other press tools. The invention is mainly applicable to small, simple or complex shape punched sections, the section of which is

  o the material does not allow the implantation of a screw of

  be euffisant to assess their maintenance.

  These punches are generally retained by dorning to their ex-

  not active a larger section. This solution often presents inconvenient disassemblies and especially

  manufacturing difficulties, in particular with the "elektro" machines

  wire erosion. "It obliges the oas appropriate the making of

  symmetrical punches called "right and left".

  The device, according to the invention, makes it possible to remedy oes

  inoonvénients. It is particularly suitable for setting

  Elements such as punches in their positioning housing that has their support plate. I1 has a set of

  two complementary wedges forming a right parallelepiped con-

  kept in a dwelling next to that of the element to be fixed, a

  corners has at least one hole adapted to receive a life

  to train him, so as to increase the stacking

  both corners, causing a pinch

the element to fix.

  According to a preferred embodiment, the second so-called fixed corner is replaced by a part of the support element having the

  mime forms and fulfills the same fonotion.

  FIG. 1 represents an exploded view of the device according to

  the invention has a partial view of a support block (7).

  Figure 2 shows in section the device mounted in a doorframe.

  The following figures represent variants of the dispoli-

  The device shown in FIGS. 1 and 2 is contained

  in a housing (b) of the support plate (6) adjacent to the housing

  (a) containing the element to be fixed (4). It includes a set of

  two complementary corners (1 and 2) forming a parallel

  the right elephant and at least one life (5) that crosses and leads

  the movable corner (1) to make it glide according to its plan

  1 oliné on the fixed corner (2), the face of the corner bears on the e-

  element to fix (4) marrying its oontaot surface. The move

  of the movable wedge (1) makes the stacking dimension of the

  two corners thus pinching the blocking of the

  (4) in his dwelling (a). The screw (5) is screwed into the support block (7); my axis, for ease of manufacture, is perpendicular to the faces of the support plate (6) and the

  support block (7). The slight displacement of the corner (1) towards the

  element to fix (4) is allowed by the game of the screw in his -passage. The corners (1 and 2) are usually made in a

  material similar to the support plate (6).

  The number of life (5) and its dimensions, as well as the di-

  (1 and 2) are determined according to the characteristics

  of the element to be fixed (4).

  FIG. 3 represents in section a variant of the device

  where the fixed wedge (2) is replaced by a part of the

  that support (6) having the same shape and fulfilling the same function. This same figure represents another variant where the screw (5) passes freely through the support block (7) and is screwed

in the movable corner (1).

  Figures 4, 5, 6 and 7 show examples where a single device is adapted to fix several punches (4)

  relatively close to one another by cooperating with

  intermediate wedges (8) in Figures 6 and 7, or having a special shape according to Figures 4 and 5. The movable wedge (1) on the latter then has two faces

  in contact with the punches (4), these two faces of ap-

  and its oblique face and that of the possible fixed wedge

  (2) are contained in planes forming a tetrahedron. Of the-

  placement of the corner (1) towards the bottom of the housing then causes a simultaneous thrust on its oblique face and on both

  faces in contact with the punches (4).

  According to FIGS. 8 and 9, the device according to the

  variants previously described and able to be

  in a group to fix one and the same punch or element (4).

  These same figures illustrate a variant of the screw (5) which

  is a grub screw with two threads, the steps of which are different.

  puts an easy unlock of the device.

  FIGS. 5 and 7 also show two examples where the movable eye (1) is entrained in the nene of loosening,

  in addition to the tightening direction, by the screw (5) whose head is
