Embodiment Construction

[0034] according to figure 1 In the case of the device 10 according to the invention, a rotationally symmetrical circular blank 1 of sheet material is clamped centrally and axially between the spinning die 12 and the counter-carrier 20 for the production of the deformed part. The clamped round blank 1 is set in rotation by a rotary drive (not shown).

[0035] Compression rollers 50 with roller base bodies 52 are fed radially from the outside at the outer edge of the round blank 1 . A compression region 54 with a surrounding shaped groove 56 is formed in the middle section on the roller base body 52 . The outer edge of the circular blank 1 is housed in a shaped groove 56 which presets the outer contour of the area of ​​the circular blank to be compressed.

[0036] The roller base body 52 is seated on a compression roller shaft 74 , which is rotatably mounted in a bracket 80 via a radial bearing 76 and an axial bearing assembly 78 . The support by means of the radial bearing ...

Abstract

The invention relates to a method and a device for producing a shaped part from a circular blank, wherein the circular blank is rotated and at least one compression roller is radially applied to an outer edge of the circular blank, said compression roller having a circumferential shaping groove. The outer edge of the circular blank is compressed to form a thickened region, which is shaped according to the shaping groove of the compression roller to form a thickened edge contour. With the radial compression, at least two axial shaped rollers are applied to an outer region of the circular blank,which cooperate when shaping the edge contour. According to the invention, at least in a starting phase of the radial compression, the two axial shaped rollers are applied to the thickened region atan axial shaping distance to one another, which distance is smaller than an axial width of the shaping groove of the compression roller, wherein the thickened region is axially compressed back.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for producing a deformed part (Umformteil) from a round blank (Ronde), in which the round blank is placed in rotation and at least one compression roller A stauchroller, sometimes called an upsetting roller, is radially fed (zustellen) to the outer edge of the circular blank, the compression roller has a surrounding forming groove (Formnut), and the outer edge of the circular blank is Compression (stauchen, sometimes called upsetting) into a thickened region corresponding to the forming grooves of the compression rollers shaped into a thickened edge profile, and in radial compression at least two axial Forming rollers (the at least two axial forming rollers interacting during the shaping of the edge contour) are placed or advanced laterally on the outer region of the round blank. [0002] Furthermore, the invention relates to a device for producing deformed parts from a round blank a...
