Abstract

The invention discloses an integral hot working sizing tool for disc parts. The integral hot working sizing tool for the disc parts comprises a disc part, a bolt, a gasket, a pressing body and a nut, wherein the disc part is arranged on the pressing body and is pressed and corrected through the bolt, the gasket and the nut; a plurality of oil grooves are formed in one side face of the pressing body; and a conical face is arranged on the other side face of the pressing body. According to the integral hot working sizing tool for the disc parts provided by the invention, heat treatment deformation of the disc parts can be effectively controlled, synchronous heat correction is conducted in the tempering process of heat treatment, the problem that the parts are greatly deformed under the action of heat stress and structural stress in the heat treatment process is solved, and the deformation of the parts is controlled within the range of finish machining and reserved grinding amount, so that the processing quality of heat treatment is ensured, and economic benefits are created for factories.

Description

technical field [0001] The invention relates to the technical field of thermal processing of disk parts, and in particular relates to a shape-calibrating tool for overall thermal processing of disk parts. Background technique [0002] The clutch inner hub in the company's high-power transmission products is a disc-type part. The average wall thickness of this part is 5mm, the outer diameter of the part is 202mm, and there is an inner cylinder tooth structure. The design requires heat treatment of 35-40HRC. Since the hardness is difficult to machine, the parts are in the state of precision machining before heat treatment, and only the amount of grinding is reserved. During the heat treatment process, the parts will undergo large deformation due to the action of thermal stress and tissue stress, and there are opening spaces, making the deformation more difficult to control. At present, manual shape correction is used for shape correction. There are many problems such as unrea...
