Problems solved by technology

[0009] In view of the large deformation of the disc blade of the high-precision slitting machine in the prior art after heat treatment, when the heat-treated deformation layer is eliminated in the subsequent finishing process, the tooling for fixing the disc blade is easily deformed, resulting in insufficient processing accuracy and low product qualification rate, which is time-consuming and labor-intensive. problem, the present invention provides a manufacturing method of tooling for processing heat-treated deformed disc blades, which makes the tooling have the advantage of not easily deforming through reasonable composition and heat treatment process corresponding to the components, and when used to fix the disc blades , can quickly eliminate the deformation layer of the disc blade, improve the processing accuracy of the disc blade, and improve the qualified rate of the product

Abstract

The invention discloses a manufacturing method for a tool for machining a heat treatment deformation circular-disc blade. The manufacturing method comprises machining of a tool main body and machining of a tool accessory and comprises the following steps: (1) preparing tool main body raw materials; (2) annealing a forged blank; (3) initially machining the forged blank into a tool main body; (4) carrying out heat treatment on the tool main body; (5) deeply machining the tool main body; (6) detecting the tool main body; (7) preparing tool accessory raw materials; (8) annealing a forged blank ofthe tool accessory; (9) turning of the forged blank of the tool accessory; and (10) tightening the tool main body and the tool accessory together by using a bolt for combined use. According to the invention, through reasonable ingredient composition and a heat treatment process corresponding to the ingredient, a deformation-free effect of the tool is achieved; and during fixing the circular-disc blade, a deformation layer of the circular-disc blade can be rapidly eliminated, so that the machining accuracy of the circular-disc blade is improved and the qualified rate of products is increased.
