Definitions

  • the invention relates to a method and an apparatus for producing an internally and externally toothed cup-shaped sheet metal part according to the preamble of claim 1 and of claim 7 and is based on a prior art, as he WO 2009/124534 A2 and the EP 2 460 599 B1 has become known.
  • the invention essentially uses a generic device and a generic method, as shown in the two aforementioned publications. For this reason, because of the basic functions of the present invention and the device structure, reference may be made to the disclosure of the two aforementioned publications. Disadvantage of the method and the device according to the WO 2009/124534 A2 is that the movable forming head, are arranged in the circular spaced-apart circumferentially distributed cassettes for receiving profile rollers, a relatively large space requirement.
  • the core of this document is that the forming head rests from the outside on the sheet metal part to be formed and that consequently also the cassettes in which the profile rollers are arranged to create from the outside to be formed sheet metal part and deform this directed radially inward. It is mounted as an alternating internal and external teeth on the sheet metal part, but the deformation is done by the outside of the sheet metal part by attaching profile rollers.
  • Another disadvantage of the known device is that the forming head requires a lot of space. For this reason, an external roller receptacle must be arranged on the cassettes, which receives the pressure of the profile rollers on the cassettes, which is directed radially outward. Such a pressure receiving part or such a receiving ring is relatively difficult to manufacture and must be made relatively stable, and requires appropriate slot.
  • the invention is therefore the object of developing a method and apparatus for producing an internally and externally toothed cup-shaped sheet metal part so that with less space and lower production costs of the forming and sheet metal parts can be transformed with an outwardly directed flange.
  • the invention proposes to make a similar deformation directed from the inside to the outside on the sheet metal part.
  • the forming head according to the invention works with profile rollers, it will be referred to below as a roller head. However, this designation is also retained if, instead of the profile rolls, other forming bodies are used, e.g. the alternative pressure and Ziehumformwerkmaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschinemaschine
  • profile roll used in the description of the invention is therefore not intended to be limiting. It can be used all Umform stresses or drawing or pressure body, such. Plungers that work in the manner of a spinning tool or achslose rollers, balls, cylinders, pins and the like.
  • the forming head must be at least as large in its outer circumference as the inner circumference of the sheet metal part to be formed. This results in the need to produce a relatively small building forming head, which in turn has the advantage that the actual power of the cassettes can now be provided in the center of the forming and there a stop bushing can be arranged with a relatively small circumference, covering the entire , inward forming pressure acting on the cassettes adopts.
  • a stop sleeve located in the center of the forming head is provided, which can be made much simpler, cheaper and more space-saving for this reason.
  • the invention therefore provides, in principle, for a forming head to extend into a clamped, cup-shaped sheet-metal part, and because of the forming bodies, preferably profile rolls, rolling along the wall of the sheet-metal part along the inner circumference, alternating internal and external toothing occurs because the sheet metal part is surrounded on its outer periphery by an associated, provided with a complementary toothing die.
  • the annular die thus acts with its teeth as a support body for mounting the teeth in the sheet metal part. While the Umform redesign work directed from the inside out, puts on the outside of the sheet metal part, the die with its complementary teeth.
  • the invention is not limited to a forming head on which the cassettes are arranged with outwardly directed forming bodies (preferably profile rollers) and which moves into the interior of the sheet metal part to be formed.
  • Such a combined roller or forming head consists of a ring of external cassettes, the forming bodies (preferably profile rollers) are directed radially inwardly on the outer periphery of the sheet metal part to be formed, and further comprising a combined further roll or forming head according to the present invention, which is equipped with a number of uniformly distributed on the circumference arranged cassettes whose forming bodies (preferably profile rollers) act from the inside to the outside.
  • the quality of the component is significantly improved, because a subsequent attachment of a collar by a separate forming process can be omitted. In such a previous forming process, the accuracy of the subsequent gearing can be affected.
  • a wiper which is movable separately from the forming head (preferably roller head) is arranged on the upper tool of the device. This scraper ensures the ejection of the sheet metal part after the forming process.
  • a non-adjustable set of forming bodies (roller set) is described, which is characterized in that the forming bodies (profile rollers) receiving cassettes abut straight cylindrical guide surfaces on the inner stop sleeve and therefore not radially during the deformation process are adjustable.
  • the invention is not limited to cassettes, which are arranged only in one plane on the forming head (roller head), a combination of several superposed cassettes is possible to perform the transformations of the invention.
  • Such combinations of multiple cassette rings are used to provide different processing steps, such as e.g. a post-processing of the applied teeth with another set of profile rollers to realize.
  • a radial adjustment of the forming body takes place in the direction of the workpiece to be formed in such a way that, for example, on the tool-side stop sleeve supporting back plates of all sitting on the ring cassettes with a thickness X1 by respectively a back plate are exchanged with a different thickness X2 and thus the cassettes overall more radially outwardly protrude as compared with thinner back plates, which ensure that the cassettes with a smaller amount radially from the forming head (roller head) stand out.
  • the depth of the deformation of the toothing can be adjusted by replacing the respective back plate on the respective cassette.
  • the cassettes are not aligned in the radial direction exactly from the inside to the outside and therefore also work the profile rollers on a radius beam, but that they are installed by a deviating from the radius beam angular position in the cassette or Cassette sits in a different angle beam on the stop sleeve, as for example in the DE 10 2010 053 547 A1 is described.
  • the invention thus provides a device and a method in which it is provided in a development that the profile rollers or forming bodies do not work on a radius beam, but offset to the radius beam in an angular position.
  • a die or another ring-shaped holder is inserted between the inner and the outer wall of the sheet metal part, wherein the die has a complementary in comparison to the rolled-up of the profile rollers teeth complementary teeth.
  • Such toothing of the die can optionally act only on the radially outer periphery of the sheet metal part or act only on the radially inner periphery of the sheet metal part or on both peripheries of the sheet metal part with different or the same tooth shapes.
  • the forming device according to the FIGS. 1 to 3 consists essentially of an upper tool 1 and a lower tool 2 arranged thereunder.
  • a number of downwardly directed guide columns 3 are present, which dip when lowering the upper tool 1 in the direction of arrow 27 against the lower tool 2 in the guide receptacles 4.
  • a recess 44 is arranged in a clamping plate, in which further retaining plates a counter-holder piston 7 movable is arranged.
  • the drive of the counter-holder piston is not shown in detail. This dips through an annular space 24, which is arranged centrally in the interior of a ring holder 10.
  • a die 5 with an associated, inwardly facing toothing 6 is arranged on the ring holder 10.
  • the still undeformed sheet metal part 9 sits on, with an inner centering on the mold plate 8 takes place.
  • the sheet-metal part 9 has a flange 43 which is equipped with a larger circumference and directed outwards. An attachment of a toothing by a forming head (roller head 23), as described in the prior art, would therefore not be possible.
  • a forming head 23 is provided with from inside to outside reshaping bodies (profile rollers 22).
