发明名称 Method for producing an annular element comprising an inner toothing, especially a sliding sleeve, and device for carrying out the method
摘要 A method for producing an annular element having an inner toothing, especially a sliding sleeve. An outlet ring element can be arranged in an extrusion device which includes an annular matrix element with an inner bore hole, a sleeve stamping device which is arranged therein and has first and second annular sleeve stamping elements which can be moved in relation to each other in the inner bore hole, and an inner stamping device having first and second inner stamping elements and first and second partial regions which are interspaced in the circumferential direction. When the inner stamping device is closed, the partial regions form cavities for producing the inner toothing. The outlet ring element is arranged between the first and second inner stamping elements and is measured in such a way that when closing the sleeve stamping device, material from the outlet ring element flows into the cavities for the formation of the inner toothing.
