    An arrangement for profiling forwardly indexed material webs for producing e.g. parallel, transverse undulations in a sheet metal web (6) of uniform width which is forwardly indexed through a forming space (5) located between a lower bed (1) having a die (3) with an upwardly turned forming surface (4, 21) above which is a holding device (8) carrying a punch mechanism (7) reciprocatingly driven relative to the die (3) and executing a forming stroke while engaging the web and the forming surface of the die. An inclined ramp (22) guides the incoming web obliquely downwards towards the forming location (21) on the forming surface. Close to the ramp is a web support body (20) yielding transversely to the plane of the ramp when the web is stretched over the body during profiling by the forces of the punch mechanism (7) located beneath (9) the holding device which is formed as an attachment plate (8) movable in relation to the bed (1) and has a punch tool (10) extending from the plate (8) and a holding punch (12) axially movable along the punch tool and mounted on guide means (13) attached to the plate (8) and held forwardly biased in an outwardly protruding position by spring devices (16) acting between the plate and the holding punch.

    专利说明:

    The invention relates to sheet punching, in particular to devices for corrugating thin tape materials.
    The purpose of the invention is to improve the accuracy of molded tape material products by eliminating material slippage during the formation of corrugations.
    The drawing shows a General view of the device.
    The device comprises a base 1 having a groove 2 in which the matrix 3 is placed. The matrix 3 has a molding section 4 and a pressing section 5.
    The molding section 4 can be made in the form of a recess 6 with inclined walls. Before the molding section
    the supply side of the tape material (the feed direction is indicated by arrow A) is a protrusion with a plane 7 inclined to the wall of the depression 6. The base 1 also has a protrusion, the plane of which 8 is made adjacent to the plane 7 of the matrix projection and with the same angle of inclination. In front of the protrusion of the base, an elastic element 9 is placed, which can be made in the form of a roller and rubber or plastic and is installed in the recess 10.
    On the base 1, on the side of the die pressing section 5, a means is also fixed for limiting the lifting of the tape material in the form of a pad 11 with a restriction groove 12.
    The device also has a mounting plate 13, the carrier still fixed

    a bending punch 14 with a bending edge 15 and working planes 16 and a clamp 17 mounted on guide rods 18 fixed to the plate 13 with compression springs 19 and having a working surface 20 with a number of acute-angled tips protruding below the bending edge 15 and a plane 16 bending punch 14.
    The device works as follows.
    When lowering the fastening plate 13, the clamp 17 presses the profiled section 22 of the tape material to the section of the clamping of the matrix 3. At the same time, the section 23 is fixed between the stationary section 22 and the tape material clamped in the feeding unit 21 and rests on the elastic element 9, However, in the process of deformation the punch 14 due to the ability of the elastic element 9 to compress in the direction perpendicular to the planes 7 and 8, the section 23 has the ability to move along the planes 7 and 8, filling the cavity 6 of the matrix 3, however, since The strip material portions 23 are arcuate and curved in a certain way due to the displacement of the plane of clamping of the flat material in the feeding unit and the feeding plane of the shaped section 22 of the tape material and adhesion of the protrusions on the matrix and the base 7 and 8 on the matrix and the base (preferably 20., 40 ° depending on the thickness of the material and the dimensions of the corrugations), the edge 15 of the punch 14 is in exact contact with the top of the molded corrugation during the whole deformation process.
    When lifting the plate 13 with the punch 14 and the clamp 17, the shaped section 22 under the action of the elastic forces of the element 9 and the arcuately curved section 23 rises under the surface of the matrix 3 to a height bounded by the upper wall of the groove 12 of the block 11 and moves by the feed unit 21 to the corrugation step.
    The device provides high-quality corrugated products from thin-sheet material with minimal stretch.
