    The invention relates to a tooling for the pressure treatment of sheet material and can be used to combine finishing cutting and punching holes in presses of simple action. The purpose of the invention is to improve the surface quality of the parts produced. This is achieved by supplying the punch with a punching waste ejector, which install a die punch (M) in the working window, opposite to the punch for punching and perform with a conical protrusion (B) on the working face, as well as performing conical projections on the working ends of the PM and matrix (M) for cutting. In on the MI, a step is performed, in the area adjacent to the working edge, the stage has a cross section corresponding to the working contour M, followed by a flat platform, then a conical section. Against this area, the conic surface of the ring B is also located on the M. At the working stroke B on the PM and M, the material is squeezed out in the zone adjacent to the cut out contour, and then the ejector B expands the material in the zone adjacent to the hole being punched. The separation of the material is carried out in a state of tight compression. 2 h. N. f-ly, 1 ill. § CO: o ffi cm

    The invention relates to a tooling for the pressure treatment of sheet material and can be used to combine finishing punching and punching on presses of simple action.
    The purpose of the invention is the superior surface quality of the parts produced.
    The drawing schematically shows the strain, a longitudinal section.
    The stamp contains a stationary lower plate 1, a matrix 2 fixed on it for cutting parts, an ejector 3 of cut parts placed in the working window of matrix 2, a punch 4 for punching holes mounted in the cavity of the ejector 3. In the other part of the stamp the top plate 5 mounted is fixed there is a die 6 and a punching waste ejector 7 in the last hole, equipped with a spring 8. The ejector 3 through the rods 9 rests on the yoke 10, which is spring-loaded in the direction of the die 6 with a spring I1. Ejector 7 is associated with a press pusher 12 (not shown), and plate 5 is associated with a press slider 13. Matrix 2 for punching has a protruding annular portion a bounded by a conical surface b. The die 6 has a stepped protrusion in the end with a cylindrical step r whose contour corresponds to the working contour of the working window of the die 2, a flat annular platform e and a conical section e. At the end of the ejector 7 there is a conical protrusion; the contour of the larger base corresponds to the contour of the punch 4 for punching.
    The stamp works as follows. After the shaving machine (press) begins to move, the cutting edge of the punch-die 6 reaches the flat sheet to be machined, after which the conical annular surfaces lying one against the other draw the material of the sheet to be worked radially outwards along the extruded contour. At this time, the flat surface areas of the protrusions of the quince compress the material.
    At the same time, the ejector 7, overcoming the force of the spring 8, moves in the opposite direction and firmly presses against the upper plate 5. After
    62
    This extrusion cone and ejector 7 squeezes the material of the sheet being processed along the inner contour of the cut surface in the radial direction. Thus, both along the internal contour and along the external contour, hydrostatic pressure occurs in the material of the sheet being forged, therefore on the surfaces
    cuts can not cause tears and cracks. The entire work process is carried out in this way only under cutting stresses.
    After reaching the bottom position, the slider 13 moves upwards, the pushed piece is removed from the die with a compression spring 11, traverse bars 10, rods 9 and the ejector 3. At the same time, the waste of the hole is pushed out of the die with the help of a pusher 12 of the press.
    The use of the invention makes it possible, when installing a stamp on a simple action press, to combine the final cutting of parts with the finishing
    punching holes in them to provide separation surfaces with high purity.

    Claims (3)
    [1]
    1. Combined stamp for finishing cutting of parts and punching holes in them on presses
    a simple action, containing a matrix for cutting, placed in one part with the possibility of relative axial movement, with an annular section bounded by a conical surface, an ejector of cut parts located in the working window of the matrix, mounted in the cavity of the ejector a punch for punching holes, and also placed
    in another part of the punch-matrix, which is characterized by the fact that, in order to increase the quality of the surface of the parts produced, it is equipped with a punching waste ejector placed in the working window of the punch-matrix opposite to the punch for punching and with a conical protrusion on the end, and also provided with a protrusion located on the working
    the end face of the punch matrix having a stepped shape with a step with a smaller cross section opposite the working window of the matrix and a step
    313
    with a large cross-section bounded by a conical surface, opposing (to it the conical section of the matrix.
    [2]
    2. A stamp according to claim 1, which differs from the fact that a flat annular platform is made on the protrusion on the working end of the die-punch between a step of smaller diameter and a step limited by a conical surface.
