Definitions

  • the invention relates to a method for producing stamped parts in a tool, in particular a fineblanking tool, by means of at least one stamp, with which the stamped part is pressed out of a strip of material, wherein the stamped part is pushed out of the material strip from this to a discharge after the pressing out.
  • Stamped parts are usually produced today on punching machines in a tool, which consists of an upper and a lower tool part, between which a strip of material is clamped. Corresponding stamps then press the stamped part out of the material strip. When opening the tool these punched parts are ejected.
  • a corresponding fine-cutting device is, for example, in the DE 35 76 129 A1 shown.
  • a fineblanking tool can be found in the DE 197 51 238 A1 ,
  • the stamped part is also pushed back into the strip of material and discharged with the strip of material.
  • this pressing back has the disadvantage that the stamped part often suffers damage to the functional surfaces.
  • the present invention has for its object to develop a method and an apparatus of the type mentioned above, with which the stamped part can be easily, sorted and discharged without damage.
  • the punch cooperates with a counter-holder in a cutting plate, wherein during punching of the stamped part, this is pressed against the force of the counter-holder in the cutting plate. If now the cutting plate is removed from the punch, then the counter-holder pushes the punched part out of the cutting plate again, so that it preferably comes to lie on the surface of the cutting plate. On this surface, the stamped part is then pushed along by means of the material strip to the discharge.
  • a device which determines the relative position of the material strip relative to the cutting plate and, if provided, also with respect to the press plate in which the punch is guided.
  • the strip guides are made use of, which already hold the material strip between the prior art and pass it through the punch.
  • These strip guides are now designed to form a receptacle with which it is possible to move the material strip relative to the cutting plate and / or the pressing plate. For this purpose, it may be advisable that this recording is movable parallel to the punch or the counter-holder.
  • the punched part is formed an increase, which is incident on a control edge on the material strip.
  • the method according to the invention and the corresponding device have the great advantage that the stamped parts, in particular fineblanked parts, leave the tool space separated from the inner mold and precursor wastes. This is done without damage, since there is no risk that they remain between the two mold halves and are damaged in a subsequent punching operation.
  • FIG. 1 From an inventive device for producing stamped parts 1.1 is in FIG. 1 a part of a tool P and shown a part of an upper tool part 2 and a lower tool part. 3
  • a press plate 4 is partially shown, in which a punch 5 is performed for cutting the punched part 1.1.
  • a punch 5 is performed for cutting the punched part 1.1.
  • further inner dies 6.1 and 6.2 can be seen with which 7 precursor and / or inner mold waste are cut out of a strip of material in the cutting process.
  • a corresponding waste 8.1 falls through a conically widening bore 9 in an insert 10.
  • the punch 5 is associated with a counter-holder 11, wherein in the counter-holder 11, a further inner forming die 6.2 is guided by means of a waste 8.2 is pressed into a conically widening bore 12 in the punch 5 and disposed of through this hole.
  • the material strip 7 is further associated with a device 15 for lifting the material strip 7.
  • This has a in the press plate. 4 guided piston 16, which is assigned a bolt portion 17 with a smaller diameter and then a guide piston 18 with a larger diameter. In this way, a receptacle 19 is formed in the region of the bolt portion 17 between the piston 16 and the guide piston 18, in which the material strip 7 is guided and held.
  • the strip of material 7, guided in the device 15 for lifting the strip of material 7, between the upper and the lower tool part 2 and 3 is introduced.
  • the tool P is closed, wherein the guide piston 18 is immersed against a spring-loaded counter-piston 20 in a guide bore 21 in the cutting plate 10.
  • the inner mold punch 6 cuts out of the strip of material 7 from the waste 8.1, which falls away through the hole 9 down.
  • the stamped part 1.1 is cut out of the strip of material 7, wherein plunger 13 and counter punch 14 are set so that an upwardly projecting support member 22 is formed on the stamped part 1.1.
  • the inner forming die 6.2 ejects the waste 8.2 through the bore 12 in the punch 5.
  • the tool P as in FIG. 2 shown, with the cutting plate 10 away from the pressing plate 4 runs. Partially this movement is also followed by the piston 16 so that the material strip 7 is lifted off the pressure plate 4. However, the device 15 is adjusted so that the material strip 7 is also lifted off the cutting plate 10 and adheres to it by a defined distance a which is at least as great as the thickness d of the material strip 7.
  • the material strip 7 is moved to the right, as indicated by the arrow 23.
  • a control edge 24 of the material strip 7 strikes the support part 22 of the stamped part 1.1 and takes this stamped part 1.1 up to a discharge, which is formed by a dropout slope 25.
  • the stamped part 1.1 drops the dropout slope 25 along or on a discharge conveyor belt and is now discharged for further processing.
