Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hard alloy die machining, in particular to a machining method of a bent tooth die outer sliding block. BACKGROUND

[0002] The bent tooth die outer sliding block is mainly applied to pressure vessels, and the material of the bent tooth die outer sliding block is generally YG hard alloy and Cr12 steel with a hardness of HRC58. The hardness requirement is high, and the numerical control equipment needs small feed amount and slow feed speed for machining the workpiece of high hardness material. In addition, the machining is single piece, and the efficiency is not high. At present, the machining of the bent tooth part of the bent tooth die outer sliding block generally uses a bench clamp for clamping, and the bent tooth part is machined by a numerical control machine tool. When single piece machining is performed by clamping with the bench clamp, the force during clamping of the bench clamp cannot be too large to damage the workpiece. However, due to the action of the machine tool during machining, slight changes in the position of the workpiece are easily caused, so that the machining precision cannot be guaranteed. SUMMARY
