Rollform- oder Wellmaschine

摘要

Apparatus for forming toothed workpieces by rolling them in high-pressure contact with a single forming die. The workpieces are held in precise relation with the die during at least the final stage of the rolling operation by a support assembly having one or more pilot surfaces, each pilot surface being in rolling contact with a pair of rigidly mounted backup members. The pilot surface or surfaces and the backup members locate the axis of the workpiece with respect to the axis of the forming roll. Separate support members positively locate the workpiece along its axis during the rolling operation.
