Definitions

  • the invention relates to a die for a tool set consisting of a punch and a die for the mechanical joining of sheet metal lying on one another by forming, with an anvil and die segments, which together with the anvil form a cavity into which is inserted and which are transverse in angle ,
  • an anvil and die segments which together with the anvil form a cavity into which is inserted and which are transverse in angle
  • Preferably orthogonal to the cavity axis are slidably mounted against a spring force, and with a surrounding the Matrizensegmente jacket sleeve.
  • the spreading movement is preferably orthogonal to the cavity axis H, but it can also be made transversely upwards or downwards.
  • Such a template is for example from the EP 1 468 758 A1 known.
  • the punch is moved down onto the plates and pressed and pushes the material into the die or in the cavity formed by the die segments and the anvil.
  • the die segments must then move to increase the cavity so that the displaced material can be absorbed.
  • the known die is round.
  • the anvil is pressed into the die sleeve.
  • At the anvil are six circular segment-shaped die segments, which are each guided radially outwardly via an extension in radial circumferential slots in the die sleeve.
  • they are connected via a single spring ring (O-ring). After joining, the die segments are pulled back into their original position by means of the force of the spring ring.
  • EP 0 835 701 A2 is a push-through matrix known, which has a rectangular outer contour.
  • the anvil of this die is formed on a base body.
  • On the main body a die sleeve is placed, which is substantially closed over its circumference and has upwards only a circular recess through which protrudes the projecting part of the die segments.
  • the closed die sleeve guides the die segments and secures them from falling out.
  • the restoring force for the spring segments is applied by integrally formed with the die sleeve spring tabs, which are formed by double folds.
  • the entire die sleeve must be made of spring steel with a, due to the spring effect upwardly limited spring steel thickness.
  • a stable die protection must be placed around the die, which the working width, u. U. also increases the working thickness of the die, so that if only a limited component space is available, then as little as a round die can be used.
  • this die has the disadvantage that the cleaning is made difficult by the circumferentially substantially closed die sleeve and sometimes a cleaning is only possible by time-consuming disassembly of the die.
  • a tool for producing a clinching compound in which the wall sections of the working opening of the die are made resilient and are stopped to achieve a cold hardening of the squeezed material after covering a certain distance via a stop.
  • the EP 0 799 843 B1 discloses a tool for manufacturing joints between plate-shaped parts, which has an upper tool part with a punch and a side-pressing element and a lower tool part, which is provided with a die.
  • the punch and die cooperate to draw the material in the plates to form a hollow space in the plates and to laterally expand the lower portion of the cavity to join the parts together.
  • the die has at least two die parts which are arranged around the counter punch.
  • the template described above is to be improved so that it can be made smaller while maintaining the same stability in order to be able to be used even at complex achievable parts points.
  • the die in an orientation can be made very narrow. Because the die elements are mounted and guided in parallel opposite guide slots in the jacket sleeve, contact surfaces in the bearings are small, so that only low frictional forces occur and thus correspondingly low restoring forces are necessary. At the same time, the guide slots also secure the die elements against falling out.
  • the jacket sleeve can thus be designed to be open at the top, so that settling contaminants can be easily removed.
  • the necessary spring force can be predetermined by a suitable material and material thickness selection.
  • the outer contour can be kept narrow.
  • the springs are in particular preferably designed as leaf springs, whereby the space in the longitudinal direction of the die can be kept small.
  • the springs are preferably fastened via bolts which can be pressed into the base body. By means of these bolts and the jacket sleeve can be attached to the body.
  • the leadership of the die segments in the guide slots can be done via a respective einpressbaren bolt or guide lugs which protrude laterally from the die segments.
  • the die segments are provided at their lateral, outer ends with a through hole.
  • the jacket sleeve can also serve as a stop for Sp Schwarzwegbegrenzung for the die segments and / or as an additional support for the overlying components.
  • the die essentially consists of the main body 1 with the anvil 7 formed thereon, the jacket sleeve 3 and the two die segments 2, 2a.
  • the die segments 2, 2 a together with the anvil 7 form a cavity with the cavity axis H, to which they are mounted transversely displaceably in the jacket sleeve 3.
  • the displacement may be orthogonal to the cavity axis H or at an upward or downward angle.
  • two leaf springs 4, 4a are laterally attached, which exert a biasing force on the die segments 2, 2a and apply the restoring force to bring back after fitting the Matrizensegmente 2, 2a in their initial position.
  • the die segments 2, 2a are provided at their lateral, outer ends, each with a through hole 10, 10a, into which bolts 5, 5a can be inserted, which are then inserted into the guide slots 8, 8 'provided in the jacket sleeve 3; 8a, 8a 'are received positively, whereby the spreading movement exporting die segments are performed.
  • the bolts 5, 5a secure together with the guide slots 8, 8 '; 8a, 8a 'the die segments 2, 2a against falling out.
  • the jacket sleeve 3 is closed only laterally. It is open at the top and bottom.
  • the leaf springs 4, 4a which bear against the rear side of the die segments 2, 2a, are fixed in the base body 1 by means of bolts 6, 6a which can be driven into the base body 1.
  • the jacket sleeve 3 is fastened to the base body 1 via the bolts 6, 6a.
  • the die segments 2, 2a and laterally projecting lugs 9, 9a may be formed, which are integrally formed with the die segments 2, 2a. It is also conceivable, instead of integrally formed lugs 9, 9a, to provide four bolts which are inserted into corresponding holes provided laterally in the die segments 2, 2a, or pressed in.
