Title:
可塑性の質量体から成る、内側の螺旋状の切抜き部を備えた円柱形の物体を製造する方法並びに装置
Document Type and Number:
Japanese Patent JP5453414
Kind Code:
B2
Abstract:
A method is for producing a circular cylindrical body (10) comprising a workable mass, having at least one helical internal cavity extending in the interior of the body. The body (10) is initially produced with a straight internal recess, for example by means of extrusion. Afterwards the body is cut to a defined length. The body (10) that has been cut to length is then subjected to a rolling process by means of a friction surface arrangement (23) while being supported over the entire length thereof on a support means (16). The rolling process takes place in multiple steps, wherein a rolling movement using a first axis of rotation (25) is performed in a first step, and a rolling movement using a second axis of rotation (26) that is different from the first axis of rotation is used in a second step. There is also an apparatus for performing the method.
