Definitions
- the present invention relates to a method for producing a molded body produced by pressing or deep-drawing in m different wall thicknesses from an initially flat sheet.
- Shaped bodies made of sheet metal are subjected to different levels of stress in different areas depending on the application. For this reason, it is known to provide such For body with different wall thicknesses to aec this way on the one hand the expected loads and on the other hand to save material accordingly.
- the present invention has for its object to provide a method of the generic type, according to which a molded body can be produced in a material and weight-saving design while avoiding any welding work.
- This object is achieved in that a one-piece sheet metal part with a thickness corresponding to the greatest wall thickness of the shaped body to be used is used and, before pressing or deep drawing, only in those areas in which the shaped body is to have a smaller wall thickness, by rolling or corresponding other stretching process is reduced to the desired smaller thickness.
- a molded article produced by this process is characterized in that the properties of the starting material are in no way impaired and that additional, complex welding work and reworking of the weld seams are avoided.
- FIG. 1 shows a perspective illustration of a shaped body
- Figure 2 is a side view of the molded body according to
- FIG. 1 partially shown in section
- FIG. 3 shows a top view of the molded body according to FIGS. 1 and 2,
- FIG. 4 shows the detail designated IV in FIG. 2 in an enlarged representation
- 5 to 7 are schematic representations to illustrate various options for reducing the thickness of the starting material for producing a shaped body.
- FIG. 1 to 3 show, as an example of a shaped body in the sense of the present invention, a carrier 1 which has been produced from an initially flat sheet metal part by pressing or deep drawing.
- This carrier 1 has a greater wall thickness in its central region la than in its two outer regions 1b. This shows the detail according to FIG. 4 particularly clearly.
- the carrier 1 is made from a one-piece sheet metal part, the thickness of which corresponds to the greatest wall thickness of the central region 1 a of the carrier 1. Before pressing or deep-drawing this starting material, the sheet metal part in the later areas 1b of the carrier has been reduced to the desired smaller thickness by rolling out or corresponding stretching processes.
- Figures 5 to 7 show a schematic representation of the possibilities of reducing the thickness when rolling out.
- FIG. 5 illustrates that the sheet metal part, which is generally also referred to as a plate and is provided with the reference number 2 in FIGS then either a reversal of the rolling direction or an opening of the roller mill takes place.
- FIG. 6 shows that the reduction in thickness of a blank 2 can also take place in that the blank 2 is pushed as a whole through the roller mill 3, the roller spacing being able to be changed.
- a blank can also be pushed through a roller mill 3 with profile rollers 4 in order to achieve a reduction in the initial thickness in some areas.
- the thickness reduction may, as shown in Figures 5 to 7 is sofa ⁇ , made on the prefabricated board 2, with simple components, there is also the possibility that a reduction Blechdicken ⁇ according to the scheme of Figures 6 and 7 take place at the wound coil may ⁇ tone , in which case the boards are then separated from the coil.
