- Moldings that are particularly common in practice are container bottoms from Pressure vessels with a cylindrical jacket. According to the degree of curvature of the calotte A distinction is made between container bases, dished ends, arched bases, Hemispherical floors as well as plate floors and flat floors. With decreasing curvature or with increasing radius of curvature, the simplifies Manufacture so that especially bobbin and arched floors a one-piece blank.
- DE 100 47 491 A1 discloses a method for reshaping structures made of aluminum alloys, which reshapes a component to be reshaped by elastic shaping into a predetermined contour under the influence of external force and heating the elastically shaped component to a temperature higher than that for creep shaping and stress relaxation of the alloy required temperature, so that the component is deformed while maintaining the contour.
- This method is exemplary of methods in which forces first act in a first shaping step in order to achieve a predetermined contour of a component and in a second step a heat treatment is carried out, by means of which the stresses which have arisen are subsequently eliminated.
- This two-stage implementation of the shaping process is very complex and requires heating of the entire component in order to remove the existing stresses.
- the invention is therefore based on the object of a method and a device to propose which cost-effective a precise forming of Molded parts, in particular of container bottoms, allowed, in particular in the areas where the forming process can cause high stresses Tensions can be avoided during the forming process or occur only to a very small extent.

- An arrangement of the heat supply device from the outside is preferred the calotte, with an arrangement from the inside respectively from the outside and inside and thus a one-sided respectively bilateral effect on the transition area can be achieved.
- the heat supply device Transition area heated evenly, with a desired forming temperature is selectable for the molded part.
- the heating of the molded part at the given Temperature leads to a plastic under stress relaxation Forming the calotte in the transition area while shaping the brim.
- 120 ° C. can be specified as the preferred temperature, here depending on the material other temperatures can also be specified.
- the predeterminable temperature in the transition area between the calotte and the brim by controlling the heat supply device and / or spacing of the heat supply device from the surface the calotte or the brim is adjusted. Eventually by controlling and / or spacing the heat supply device Effective area of the heat supply device depending on the desired the area of the transition area to be heated.

- the rotation device has a rotation table with a support element and a hold-down.
- the hold-down preferably engages in the center on an inside of the molded part, in particular the calotte.
- the pressing tool and the stationary forming tool can be carried out in a common device or in separate devices.
- the pressing tool engages on the inside of the calotte, the stationary one Forming tool in a preferred embodiment of the invention, a bead is, which is also on the inside of the calotte and a crimping roller, which on attacks an outside of the calotte.
- the calotte on the predeterminable diameter and trained transition area by the heat supply device such It is possible to heat the brim to a predeterminable radius by means of plastic Material forming can be trained.
- the heat supply device has a stand element, a base element, a first and a second fastening element and a media connection and a burner.
- the first and second fasteners are used to set an angle and a distance of the Brenners opposite the calotte or for adjusting a height of the burner towards the calotte.
- the burner is through the first and / or second
- the device can be arranged so that the burner flame is at right angles to the transition area hits, with the burner at all times before and during the procedure readjustable, i.e. also at different angles to the surface to be deformed is adjustable in the transition area.
- the process in which the forming of the molded part in the transition area and its heating can be carried out at the same time becomes more advantageous Way at the temperature suitable for the material to be formed, the is preferably only about 120 ° C and in any case below an annealing temperature lies, the formation of tensions in the strongly reshaped transition area avoided from the outset between the calotte and the brim.

- the method and the device are particularly suitable for the production of bobbin-case bases and wicker-arch bases made of aluminum.
- the production of larger container bottoms usually leads to a decrease in the radii r ki of the brim 20 so that the calotte 22 and brim 20 are produced separately and are later joined together again, in particular by welded connections. This procedure is carried out in particular because tensions can usually be insufficiently avoided in a one-piece production.
- the new method and the associated device now allow container bottoms 30 to be produced in one piece with the supply of heat in the transition region 32 and to achieve stress relaxation, in particular also when a decreasing radius r ki is to be formed into a particularly strongly shaped brim 22.
