Method for manufacturing deep-drawn workpiece, involves connecting casing and flange, and deep-drawing blank such that blank is reshaped to casing with collar connected to it

摘要

The method involves connecting a casing (14) and a flange (26), and deep-drawing the blank such that the blank is reshaped to a casing with a collar (16) connected to it. The casing extends in an axial direction (32), where the blank is pressed such that the material of an outward reshaped component (14') of the blank flow along the surface area of a tool. The surface area faces the outward reshaped component of the blank, so that the casing passes over in the collar in the area of a reference bending edge (38) with a predefined inner radius (R0). An independent claim is included for a tool device, which has a spring base.
