Abstract: A flat die thread rolling machine provides a cam drive for the reciprocating slide which operates through a linkage to cause reciprocation of the slide. The cam provides a dwell which holds the reciprocating die stationary before the commencement of the working stroke to allow insertion of a workpiece into the dies while the dies are stationary relative to each other. The cam produces slow acceleration of the reciprocating die during the initial portion of the rolling operation to prevent workpiece slippage. The working stroke exceeds one-half of the machine cycle. Die match can be adjusted while the machine is running. Separate adjustment means are provided to adjust the tilt, parallelism, and pitch of the dies, with the pitch adjustment permitting pitch adjustment while the machine is running and without affecting tilt and parallelism adjustment. A hydraulic drive is provided to power the machine and provide high torque during jog operations and speed control during normal running operation.
