Title:
METHOD FOR PRODUCING ONE OR MORE CONCAVE CUT-OUTS ON A MAIN BODY WHICH IS, IN PARTICULAR, SUBSTANTIALLY CYLINDRICAL, ARMATURE, KEEPER PLATE, AND ELECTROMAGNETIC ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2019/076990
Kind Code:
A3
Abstract:
The present invention relates to a method for producing one or more concave cut-outs (32) on a main body (22) which is, in particular, substantially cylindrical, more particularly for producing one or more grooves (34) on an armature (40), a push rod (72), or a magnetic keeper plate, comprising the following steps: • providing a substantially cylindrical main body (22) having a first axis of rotation (T1), • rotating the cylindrical main body (22), by means of a lathe (24), about the first axis of rotation (T1) in a first rotational direction, and • rotating a striking tool (26), provided with a number of fly cutters (30), about a second axis of rotation (T2) in a second rotational direction opposite to the first direction, said second axis running parallel and offset to the first axis of rotation (T1), so that the fly cutter (30) engages stock-removably with the main body (22) in order to produce the cut-out (32). The invention also relates to an armature, a push rod and a magnetic keeper plate, having one or more cut-outs produced according to this method, and to an electromagnetic actuator comprising an armature of this type or a keeper plate of this type.
