    摘要: 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. All of the operating functions, with the exception of the hydraulic clamping function, are mechanically produced and controlled. Consequently, high cyclic operating speeds can be achieved.

    摘要: 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.

    摘要: A coil end-turn support structure for large dynamoelectric machines including a plurality of bracket assemblies which support the coil end-turn windings in a fixed position with respect to the main body of the machine in all directions except the axial direction. Ball bearings are captivated in slots in the bracket assemblies so as to provide free and smooth movement of the end-turns in the axial directions while providing rigid support of the end-turns in all other directions.
