ABSTRACT:
A method and press for uniformly quenching a heated annular workpiece while fixturing the workpiece to prevent distortion during quenching. The press has a conically shaped lower die for receiving a workpiece to be quenched thereon and a vertically reciprocable conically shaped upper die for clamping and fixturing a workpiece between them. The press has a generally cylindrical quench ring carried by the upper die for engaging against the lower die to form a chamber around the workpiece to immerse the workpiece in quenching fluid. The lower die has a plurality of spaced apart inlets for uniformly distributing quenching fluid around the workpiece and which are preferably angled relative to the center axis of the lower die for producing a swirling turbulent flow of fluid within the chamber to more rapidly and uniformly quench the workpiece.
