Clutch driven disc heat treatment machining tool

Abstract

The invention discloses a clutch driven disc heat treatment machining tool, belongs to the technical field of clutch machining and aims to directly carry out quenching and leveling of a driven disc atthe same time. The tool comprises an upper hydraulic mechanism and a lower hydraulic mechanism. The tool is advantaged in that profiling and quenching are carried out at the same time, flattening precision of a workpiece is guaranteed, deformation of parts under the conditions of high temperature and high pressure can be prevented while the flatness requirement is met, flatness of the driven discis ensured by ensuring the deformation of the part, so the high-temperature leveling procedure is reduced, in the quenching and cooling process of the part, the heat balance flow of the quenching oilquantity can be adjusted, that the oil quantity is sufficient during quenching is guaranteed, and the part can obtain the good quenching effect.

Description

technical field [0001] The invention belongs to the technical field of clutch processing. Background technique [0002] The driven disc in the automobile clutch is a key part of the entire clutch, which directly affects the performance of the clutch. The driven disc is a thin-walled large-size part. During the production process, it is produced by quenching after carbonitriding and high-temperature leveling. Yes, the conditions are very harsh during use, and can only be used after heat treatment. When the driven disc is subjected to the joint action of tissue stress and thermal stress after heat treatment, the deformation of the parts is relatively large, and it needs to be leveled to be practical.

[0002] The driven disc in the automobile clutch is a key part of the entire clutch, which directly affects the performance of the clutch. The driven disc is a thin-walled large-size part. During the production process, it is produced by quenching after carbonitriding and high-temperature leveling. Yes, the conditions are very harsh during use, and can only be used after heat treatment. When the driven disc is subjected to the joint action of tissue stress and thermal stress after heat treatment, the deformation of the parts is relatively large, and it needs to be leveled to be practical. The traditional leveling uses heating The flat mold uses high temperature and high pressure conditions to level the parts. The disadvantage is that the position of the parts after leveling under the high temperature and high pressure conditions is easy to deteriorate, and it is difficult to level when the deformation of the parts is large, resulting in waste products.

[0003] When using traditional production, the leveling process has the following defects: a high temperature of 350 degrees is required, and the processing cycle of each heating and cooling takes 12 hours, which is a waste of time

When the deformation of the parts in the previous process (carbonitriding-quenching) is large, it is difficult to level, and the flatness of the finished product becomes poor

In the case of high temperature and high pressure, the position of parts is easy to cause deviation
