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 deformed parts from a circular blank, wherein the circular blank is placed in rotation and at least one compression roller is fed radially to the outer edge of the circular blank, the compression roller having Surrounding shaped groove. The outer edge of the circular blank is compressed into a thickened area, which is formed into a thickened edge profile corresponding to the shaping groove of the compression roller. During the radial compression, at least two axial deformation rollers are advanced in the outer region of the circular blank and interact together during the shaping of the edge contour. According to the invention, it is provided that the two axial deformation rollers are advanced from one another in the thickened region at least in the initial phase of the radial compression at an axial forming distance that is smaller than the forming grooves of the compression rollers. axial width, where thickened regions are compressed axially in reverse direction.

Description

technical field [0001] The invention relates to a method 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 (Stauchroller, sometimes called an upsetting roller ) radially fed (zustellen) to the outer edge of a circular blank, the compression roller has a surrounding forming groove (Formnut), the outer edge of the circular blank is compressed (stauchen, sometimes called upsetting) into thickened region, the thickened region corresponding to the forming groove of the compression roller is formed into a thickened edge profile, and at least two axial deformation rollers (Umformrolle) (the at least two Axial deforming rollers work together when the edge profile is formed) and are placed or fed laterally to the outer region of the circular blank. [0002] Furthermore, the invention relates to a device for producing deformed parts from round blanks, with a drive device for driving ...
