Definitions

  • the present invention relates to a device for fixing punches and other elements in cutting tools, stamping, bending and other press tools.
  • the invention applies mainly to punches of small dimensions, of simple or complex shape whose active section where the material does not allow the implantation of a screw of sufficient diameter to ensure their maintenance.
  • the device according to the invention overcomes these drawbacks. It is particularly suitable for fixing elements such as punches in their positioning housing which their support plate has. It comprises a set of two complementary corners forming a straight parallelepiped contained in a housing close to that of the element to be fixed, one of the corners comprises at least one hole capable of receiving a screw capable of driving it, so as to increase the stacking dimension of the two corners, thus causing the element to be fixed to be pinched.
  • the second so-called fixed corner is replaced by a part of the support element before the same shape and fulfilling the same function.
  • FIG. 1 represents an exploded view of the device according to the invention on a partial view of a support block (7).
  • Figure 2 shows in section the device mounted in a punch holder.
  • the device shown in Figures 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 straight parallelepiped and at least one screw (5) which crosses and drives the movable corner (1) to slide it along its inclined plane on the fixed corner (2) , the face of the wedge resting on the element to be fixed (4) conforming to its contact surface, and in no case requiring this element a section different from that of its active part (c).
  • the displacement of the movable corner (1) increases the stacking dimension of the two corners, thus pinching the blocking of the element (4) in its housing (a).
  • the screw (5) is screwed into the support block (7).
  • the slight displacement of the corner (1) towards the element to be fixed (4) is allowed by the play of the screw in its passage.
  • the corners (1 and 2) are generally made of a material similar to the support plate (6).
  • the number of screws (5) and its dimensions, as well as the dimensions of the corners (1 and 2) are determined according to the characteristics of the element to be fixed (4).
  • Figure 73 shows in section a variant of the device where the fixed corner (2) is replaced by a part of the support plate (6) having the same shape and fulfilling the same function. This same figure represents another variant where the screw (5) freely crosses the support block (7) and is screwed into the movable corner (1).
  • Figures 4, 5, 6 and 7 show examples where a single device is suitable for fixing several punches (4) relatively close to each other by cooperating with possible intermediate shims (8) in Figures 6 and 7, or having a special shape according to Figures 4 and 5.
  • the movable corner (1) on the latter then has two bearing faces in contact with the punches (4), these two bearing faces and its oblique face as well as that of the possible fixed corner (2) are contained in planes forming a tetrahedron.
  • the displacement of the corner (1) towards the bottom of the housing then causes a simultaneous push on its face oblique and on both sides in contact with the punches (4).
  • the device according to the different variants described above is adapted to be mounted in a group to fix a single punch or element.
  • These same figures illustrate a variant of the screw (5) which is a headless screw with two threads whose pitch is different. This kind of screw multiplies the tightening effort and allows an easy release of the device.
  • FIGS. 5 and 7 also show two examples where the movable wedge (1) is driven in the loosening direction, in addition to the tightening direction, by the screw (5) whose head is trapped, by a plate (10) in FIG. 5, by a pin (9) Figure 7, or any other accessory capable of giving a support above the head of the screw (5) so that its unscrewing pushes the corner (1) and releases the punch (s) (4).
  • Figure 10 is a perspective view of a die cutting block with added elements, it shows an example of application of the device according to the invention, adapted to advantageously replace the traditional keys.
  • the elements (4 ') located at the ends of the support block (7') carry housings or notches corresponding to the four notches of the block (7 ') usually receiving the keys. Two of these notches at the same end of the block 7 'receive fixed lugs (11), the other two receive lugs (12) said to be adjustable, carrying a device according to the invention.
  • FIG. 11 illustrates this same variant, by representing the device, in front view, contained in the recess of a positioning cleat (12), itself partly contained in a notch of an element to be fixed (4 ' ) and comprising a movable corner (1) driven by a screw (5) passing through the cleat (12) which comprises a part capable of replacing the fixed corner (2) of the figures (1 and 2).
  • FIG. 12 represents another variant of the device according to the invention also applicable to the fixing of juxtaposed elements in a support block (7 ′). It varies by the fact that the movable corner is integrated into the cleat (12 ') and cooperates with an inclined part which has the element to be fixed (4') the screw (5) without head then bears on the element (4 ') so as to drive the cleat (12') which slides in the notch of the block (7 ') and then causes the elements (4') to be pinched against the tabs (11) of FIG. 10.
  • the variants of the device illustrated in FIGS. 10-11-12 are mainly adapted to elements such as dies, these possibly having to receive a shim (13) to compensate for the sharpening.
  • the invention is not limited to only the embodiments and applications described above but encompasses all the variants and modifications resulting from the same basic principle.
