Definitions
- a method for producing a housing ring that is an annular housing, for example in the form of a collar housing are known per se from the prior art, as well as annular housing, for example in the form of collar housings as such. A separate documentary proof is therefore not required at this point.
- the method steps listed above are preferably carried out in succession on a multi-stage transverse transport press, so that the housing ring can be completed in only one operation by the method according to the invention, without mechanical work, in particular mechanical reworking being required. Overall, the method according to the invention proves to be easy to handle and economical to carry out.
- a further advantage of the method according to the invention is that a semifinished product in the form of a wire bundle, a so-called wire coil, can be used as the starting material.
- the procurement, warehousing and processing can be standardized in an advantageous manner and thus simplified.
- a housing ring that is an annular housing, for example in the form of a collar housing is carried out by the novel process exclusively by cold forming.
- a mechanical processing in particular a mechanical post-processing does not take place. Rather, the finished housing ring production takes place in only one machining operation with the following method steps, which are preferably carried out successively on a multi-stage transverse transport press.
- a blank is first separated from the wire bundle, by shearing.
- a separation can be done instead of by shearing, for example, by section. It is preferable to use a wire with a diameter of 19 mm, so that the blank is circular in cross-section and has a diameter of 19 mm. The vertical extent of the blank results in dependence of the use-adjustable separation length. This can be adjusted according to the desired manner to be produced housing ring needs. It goes without saying that other wire diameters than 19 mm can be used.
- the blank end face is planed. This is preferably done by setting.
- cup-shaped recesses are respectively introduced into the blank end faces, which takes place by combined cup extruding.
- a method step for forming a circumferential annular groove can be provided by upsetting.
- a plurality of annular grooves can be formed by a plurality of successive upsetting operations.
- annular groove a design of an annular groove, a plurality of annular grooves or even no annular groove can be provided. It is essential to the invention that the finished housing ring production takes place solely by cold forming, that is to say a final production is carried out without mechanical reworking.
- a steel wire made of C15 steel is used as the wire.
- other types of steel may be used, depending on which material properties the later housing ring should have.
- a heat treatment This is preferably carried out after the step of planing, that is before the step of the combined cup extrusion.
- the inventive method relates to the production of a housing ring, ie an annular housing, for example in the form of a collar housing.
- a housing ring 2 which can be produced by the method according to the invention is shown in FIG Fig. 2 shown.
- Fig. 2 shows the final design, but not to scale.
- the starting point for the process implementation is a blank 1.
- This blank 1 is formed by separating a wire section from a wound into a federal government and in Fig. 1 not shown wire. The separation of the wound wire to create the blank 1 can be done for example by shearing.
- the blank 1 is then plungestäucht in a step of setting, namely to form flat blank end faces 3 and 4.
- the result of the process step of the planer dipping by setting is the intermediate product. 5
- the intermediate product 5 is then subjected to a combined cup extrusion in a next process step, as a result cup-shaped recesses 6 and 7 are introduced into the end faces 3 and 4.
- the result of this process step is the intermediate product 8.
- a hollow backward pressing is then carried out. This produces the intermediate product 11.
- the intermediate product 11 is then provided with a circumferential annular groove 12, which is done by upsetting. The result is formed with an annular groove 12 intermediate product 13th
