Definitions

  • the invention relates to a method for producing and layering components from individual layers, which are punched out, cut out or the like from a strip of material and the layers are pressed back into the strip of material after punching out or the like, and a device therefor.
  • Components for example for the automobile, such as connecting rods, cams, gear wheels, ring gears or the like are produced either by casting or from a relatively thick strip of material by punching out or cutting out. Such a fine blanking device is described, for example, in EP 0 183 648.
  • DE-OS 38 41 205 also describes the production of workpieces made of metal. Reference is made above all to the production of a connecting rod, the connecting rod being structurally broken down into individual simple partial profiles, which are produced by fine cutting and joined to form the finished part and connected to one another by layers. It is therefore a question of producing a structurally difficult part from different part profiles with different contours.
  • the object of the present invention is, however, simple components made of a plurality of identical layers - J - simple and inexpensive way to position each other.
  • a subsequent station can be printed out from the material strip and placed in a stacking magazine in which the individual layers are centered and connected to the component before the component is removed from the stacking magazine.
  • components of greater thickness can be produced from individual, thin, hardened lamellae by layering. These layers are preferably connected to one another in a further processing method by riveting.
  • the individual slats have the shape of the part, the number of individual slats gives the cam height. Since the lamellae are very thin (e.g. 0.1 - 2 millimeters), the lamellae can be punched out of hardened material, so that subsequent hardening or grinding is no longer necessary.
  • the layered component is a finished part. The material can already have a hardness of over 63 HRC.
  • the punching of the thin lamellae also makes it possible to produce cams with the smallest cross sections between the inner and outer contours.
  • the cams can also have very small holes, e.g. B. 1 millimeter. These holes are used to lighten the weight, to balance the mass or can be used to hold a rivet.
  • the heart of the device for carrying out the method is a punch press, in the tool of which the inner and outer shape of the layer are cut simultaneously in the overall cut.
  • a follow-up tool would also be possible, but the tolerances between the inner and outer shape become too great.
  • the cut part is pressed back into the lead frame.
  • the internal mold waste falls through the cutting punch and corresponding chutes in the machine table of the punch press and is discharged downwards.
  • a joining station follows the punching tool, in which the individual layers are collected in a stacking magazine.
  • a package stamp prints the individual slats (layers) out of the lead frame in synchronism with the ram stroke of the punch press.
  • the whole is done according to the invention either in a cycle feed unit or on a rotary indexing table.
  • the rotary indexing table switches one position further or the stack magazine is transported to the next station in the cycle feed unit.
  • an empty stacking magazine gets under the packaging stamp.
  • at least one rivet is fed to the stacking machine, in a next station the layers are centered and riveted, in a next station, for example, the finished component is printed out of the stacking magazine by a stamp, is put on a tape or Like. And is transported for final assembly.
  • the strip of material preferably reaches the punch press from a self-propelled coil reel, a corresponding belt loop control being provided here.
  • the punching machine itself is a precision punching machine with infeed feed, belt lubrication, etc.
  • the method according to the invention is possible with a 1-way falling tool, but also with multiple falling tools, which results in an additional cost benefit.
  • Figure 1 is a schematic representation of an inventive device for manufacturing and layering components.
  • Fig. 2 is a plan view of a schematically illustrated clock feed unit in the device according to FIG. 1;
  • FIG. 4 shows an enlarged section of a punch press in the device according to FIG. 1 in the region of the tool
  • FIG. 5 is a plan view of a strip of material for forming the components
  • FIG. 6 shows a schematic illustration of a further exemplary embodiment of a device according to the invention for producing and layering components
  • FIG. 7 shows a perspective view of a cam produced by the method according to the invention.
  • FIG. 9 shows a perspective view of a further exemplary embodiment of a cam, produced by the method according to the invention.
  • FIG. 10 shows a cross section through the cam according to FIG. 9 along the line XX.
  • 1 has a device R for r and layers of components on a coil reel 2, a punch press 3, an only partially indicated clock feed unit 1 and a waste reel 4.
  • a strip of material 5 is rolled in a clockwise direction from a coil reel 2, which is provided with its own drive. This strip of material 5 passes through a light barrier 6 which indicates when the strip of material 5 sags too deeply. Then the material strip 5 runs into a material inlet 7 of the punch press 3 and there passes a lubricating device 8, via which lubricating oil reaches the surfaces of the material strip 5.
  • the material strip 5 next passes through a tool H for cutting out or punching the inner and outer shapes of component layers 30, in the present exemplary embodiment of cam layers.
  • a section of the tool H is shown enlarged in FIG. 4. It consists of an upper part 0 and a lower part U.
  • This plunger 10 is connected to a clamping plate 11 and to it a cutting plate 12, in which in turn an ejector 13 and two internal form stamps 14, 15 are guided.
  • These inner form stamps 14, 15 serve to punch out inner forms from the cam layers 30.
