Embodiment Construction

[0041] exist figure 1 The component 10 shown in depicts a component 10 manufactured by conventional cross-rolling methods relative to its axis of rotation R 10 Rotationally symmetrical (only one side with respect to the axis of rotation (upper part) of the component 10 is shown).

[0042] exist figure 2 A component 1 according to the invention according to a first exemplary embodiment of the invention is shown in simplified form in . In the illustrated longitudinal axis or main axis of rotation R of the component 1 1 In the regions A and C of , the component 1 is shaped in a conventional manner and is formed rotationally symmetrically in the regions A, C. However, the component 1 according to the invention is correspondingly shaped in the central region B such that this region B is relative to the main axis of rotation R of the component 1 1 It is formed rotationally and acyclically symmetrically. Especially in said region B, the (symmetry) axis RB of this region B is d...

Abstract

The invention relates to a cross-rolling method comprising the steps of forming a component blank rotating about a main axis of rotation by means of at least two cross-rolling dies which are substantially opposite to each other with respect to the component blank, passing through the cross-rolling dies The movement along its main direction of motion produces an at least partially rotationally symmetrical and acyclically symmetrical component (1, 2) with respect to the main axis of rotation. The invention also relates to a rolling tool for producing at least partially rotationally symmetrical and noncyclically symmetrical components ( 1 , 2 ). The invention also relates to a device for carrying out the method according to the invention and a component ( 1 , 2 ) produced according to the method according to the invention.

Description

technical field [0001] The invention relates to a cross-rolling method, a device for carrying out the method, a component produced according to the method, and a cross-rolling tool. Background technique [0002] Cross-rolling methods are sufficiently known from the prior art. During cross-rolling, the rotationally symmetrical blank is formed between two cross-rolling dies. A distinction is made here between circular die rolling (Rundquerwalzenverfahren) and flat die rolling (Flachbackenquerwalzenverfahren). [0003] With circular die rolling, the blank or rolling stock is rotated about its own axis between two rollers that rotate in the same direction. The forming here usually takes place by feeding at least one roll and based on the geometry of the rolling tool surface. By means of known cross-die rolling methods, graded, rotationally symmetrical workpieces or corresponding preforms can be produced with an optimal mass distribution. [0004] With flat-die cross-rolling,...
