DEVICE AND METHOD FOR PRODUCING CLUTCH BODIES THAT ARE SUITABLE FOR SYNCHRONIZER SYSTEMS AND PROVIDED WITH TEETH OR TOOTH SECTIONS

摘要

A method and apparatus for producing clutch bodies, which are suitable for synchronizer systems and provided with teeth or tooth sections, from a blank uses and includes at least one embossing stage, composed of embossing segments and an anvil, for embossing roofs and troughs between root and tip circles into an upper face of the blank, and transfer means for transporting the blanks, First embossing segments form a first section and second embossing segments form a second section for sequential embossing within the at least one embossing stage, wherein the first embossing segments first emboss a first section, then return in relation to the second embossing segments, and thereafter the second embossing segments emboss the second section, wherein the second embossing segments are disposed next to each other in an annular arrangement, and the second embossing segments are designed to be axially movable relative to the first embossing segments of the first section.

1. Apparatus producing clutch bodies, which are suitable for synchronizer systems and provided with teeth from a blank, comprising at least one embossing stage, comprised of first and second embossing segments and an anvil, for embossing roofs and troughs between root and tip circles into an upper face of the blank, and transfer means for transporting the blanks, wherein the first embossing segments comprise a first section and the second embossing segments comprise a second section for sequential embossing within the embossing stage, wherein the first embossing segments first emboss the first section, then return in relation to the second embossing segments, and thereafter the second embossing segments emboss the second section, and wherein the first and second embossing segments are disposed next to each other and comprise an annular arrangement, and the second embossing segments are configured to be axially movable relative to the first embossing segments and the first embossing segments are configured to be axially fixed relative to second embossing segments, and the apparatus further comprises the following:
a) a trimming stage for cutting the troughs free, to form tooth bodies that project upwardly at an end face on the blank and have tooth flanks and roofs without further embossing; and b) an undercutting and shaping stage for undercutting the tooth flanks and for shaping the roofs of the tooth bodies to a final shape, the undercutting and shaping stage comprising embossing punches and a shaping anvil cooperating with the embossing punches.
