Definitions

  • the invention relates to a method and a Device for punching sheet metal parts from one Aluminum material in which in the flange areas Holes are made.
  • the invention has for its object a method or a device for punching sheet metal parts to provide an aluminum material with the mechanical resilience of holes, especially in the flange areas of sheet metal parts is significantly improved.
  • the first teaching of the invention ensures that Making one already in itself by the larger one Material strength increased mechanical strength in the Area of the hole. This is further increased by the fact that in the displacement of the aluminum material from the Hole hardening in the die takes place.
  • the invention When applying the procedure according to the first teaching the invention generally remains after the pre-deformation in the direction of deformation a thin floor adjacent to the Stand matrix. This floor can now be used, for example remove by necking and then deburring.
  • This floor can now be used, for example remove by necking and then deburring.
  • it is an advantage Method according to the first teaching of the invention thereby to design that after the pre-deformation in Hole area remaining material by shear cutting Will get removed.
  • this configuration enables for necking with subsequent deburring Completion of the hole in one step and secondly, make sure the hole is clean Has cut edges that cracking counteract.
  • the method is improved according to the first teaching the invention in that the pre-deformation and Shear cutting in one working stroke of a tool he follows.
  • the invention relates to a Device for punching sheet metal parts Aluminum materials, in particular for implementation a method according to the first teaching of the invention.
  • a device for punching sheet metal parts Aluminum materials in particular for implementation a method according to the first teaching of the invention.
  • a device for punching sheet metal parts Aluminum materials in particular for implementation a method according to the first teaching of the invention.
  • a hold-down and a die are provided and a stamp for Displacement of the material from the hole area in the Matrix is provided.
  • Such a device enables the production of a hole in the Flange areas from sheet metal parts Aluminum materials, the sheet metal parts between the hold-down device and the die are clamped and the Stamp the excess material in the hole area in the Form of the thickening prescribing form displaced.
  • This Device thus enables the production of holes in sheet metal parts, which, as already with regard to the first teaching of the invention has been carried out significantly higher mechanical strength of the Screwing points between the sheet metal parts with ensure an overall construction.
  • a simplification of the design of the device according to the second teaching of the invention is achieved in that the stamp to displace the material as Cutting punch is designed so that after the Displacement of the material into the die together with a cutting plate to complete the perforation Shear cutting enables.
  • the is particularly advantageous Device according to the second teaching of the invention that the die in the hole area one with a Retraction mechanism connected, slidable Has final stamp.
  • the retraction mechanism ensures Completion of the displacement of the aluminum material in the Die through the opening of the die in the hole area to ensure that the stamp is used to displace the material the remaining part of the die as a cutting punch and Interact with the insert.
  • the invention shown schematically in Fig. 1 The device has a hold-down device 1 and a die 2 to fix a sheet metal part 3.
  • the die 2 again has a recess 4 into which the material the Belchformmaschines from a stamp 5 from the Hole area 6 is displaced and after this displacement the thickening 7 forms.
  • Fig. 2 Device for punching Sheet metal parts made of aluminum materials have one Tool frame 8 on which a hold-down 9, a Die 10 and a stamp 11 are arranged.
  • Fig. 2 shows the embodiment of a device according to the invention in the open state with sheet metal part 12 placed on the die 10.
  • the die 10 has in the illustrated Embodiment in the hole area with a individual retraction mechanism, not shown, and one also not shown in detail Ejection mechanism connected, movable Closing stamp 13 on.
  • the movable end stamp 13 enables Displacement of the aluminum material from the hole area through the stamp and the subsequent shear cutting of the remaining material in the hole area between the stamp 11 and the base body 14 of the Die 10 in one working stroke of the stamp 11.
  • the movable end stamp 13 after the Displacement of the material from the hole area in the Thickening relative to the base body 14 of the die 10 withdrawn so that the cutting edge 15 of the Base body 14 of the die 10 is released.
  • the ejection mechanism not shown, ensures making sure that the movable end punch 13 is at the top is moved from the base body 14 of the die 10, so that the hole scraper is ejected.
  • the section shown in Fig. 3 through a Hole made according to the invention in the flange area of a sheet metal part 3 shows the thickening 7 along the Circumference of the hole.
  • the method or the device according to the invention ensure a Thickening 7 with a homogeneous material structure and partial work hardening with clean at the same time Hole edges.
  • the method according to the invention or The device according to the invention are therefore suitable especially for non-hardenable aluminum sheet alloys, since these are regularly in a soft state are formed and thus often in the flange area for one Mechanically sufficiently robust screw connection too soft are, as well as for curable sheet materials, which in T4 condition (cold hardened) deformed or used become.
