A closed die forging machine is disclosed in which the dies are clamped in their closed position by a hydraulically operated piston and cylinder means. A spacer is positioned between the clamping means and the movable die during the forging operation. Subsequent to the forging operation, the clamping means are released and the spacer is removed so that the movable die can be mechanically moved to its fully open position. By combining a removable spacer and hydraulic clamping means, it is possible to produce high die clamping forces without requiring substantial fluid flow to and from the clamping means. Therefore, pumping requirements are reduced and the tendency of the hydraulic fluid to become excessively hot is substantially reduced. Immediately after the completion of the forming operation within the closed die cavity, the hydraulic forces are released and a spring-powered system controlled by a cam-operated operator causes partial ejection of the finished workpiece from the stationary die. This minimizes the tendency of the fixed die to be excessively heated by the workpiece and improves die life.

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.

The invention is a better road planing vehicle having an improved suspension system for supporting the rotary cutting unit under the vehicle chassis. The suspension includes a pair of lift and tilt cylinders connected in parallel spaced relation at one end to the vehicle frame and at the other end to the top of the cutter housing. Three parallel and triangularly arranged drawbars are connected at one end to the cutter housing and extend either fore or aft to connect at their other ends with the vehicle frame. A sideshift cylinder is connected between the frame and one of the drawbars. In the preferred embodiment the connections of the lift cylinders and the drawbars are ball joints.
