Embodiment Construction

[0149] figure 1 A device 100 for carrying out a method of cold forming a workpiece 1 is shown. The workpiece 1 is held in the workpiece fixture 10 (in figure 1 is shown symbolically in ) and has a longitudinal axis Z which is at the same time the longitudinal axis of the workpiece 1 .

[0150] In the example shown, the workpiece 1 has a machining region 11 which is rotationally symmetrical with respect to the longitudinal axis Z and has an outer surface 11 a which is designed, for example, as a cylinder and into which profiling is to be incorporated, and the second A region 12 adjoins it, wherein the second region of the workpiece 1 has a larger diameter than the machining region 11 . As a result, a contoured delimiting structure designed as a workpiece shoulder 13 is formed between the regions 11 and 12 .

[0151] further provided in figure 1 The orbiting body 8 shown symbolically in Fig. figure 1 not shown) orbital motion and thus perform a rotation R8'. The tool holde...

Abstract

The invention relates to a method and to a device for producing a shaped body with shaping by cold-forming a workpiece (1), the workpiece having a longitudinal axis (Z) and an outer surface (11a), for example a cylindrical outer surface, which extends along the longitudinal axis (Z) in a working area (11), and to which the shaping (P) is applied. The workpiece (1) carries out a rotational movement (R1) about the longitudinal axis (Z) and is worked by a tool (2) in multiple forming actions, during each of which an operative part (21) of the tool (2) comes into contact with the working area (11). The tool (2) is held by a tool holder (5), and the tool holder (5) is rotationally mounted in a rotating member (8) about an axis of rotation (W) and is driven to perform a rotary movement (R5) about its axis of rotation (W), and is driven by the rotating member (8) to perform a rotating movement (R8). The rotational movement (R1) of the workpiece (1) is synchronized with the rotating movement (R8) of the tool holder (5), and the rotary movement (R5) of the tool holder (5) is synchronized with the rotating movement (R8) of the tool holder (5).

Description

technical field [0001] The invention relates to the field of profiling, for example, of rotationally symmetrical solid or hollow parts, in particular by cold forming (also called cold forming). The invention relates to a device and a method according to the preambles of the patent claims. Background technique [0002] Different methods for profiling solid or hollow parts by cold forming are known in the prior art. [0003] For example, it is known to profile a hollow part in a single step by means of a device for profiling a non-formed sheet metal part comprising a number of tools distributed around and which when inserting the sheet metal part into the device Cutting into the sheet metal part where the profiling gap is to be created. A corresponding method for producing an internally and / or externally toothed pot-shaped sheet metal part (with a toothing extending towards the center axis of the pot) is known, for example, from DE 10 2014 002 971 A1. [0004] The disadvant...
