Embodiment Construction

[0019] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0020] A method for manufacturing clutch pressure plate rivets is carried out in the following order:

[0021] The first step is to use No. 20, No. 35 or No. 45 steel coils or steel bars as raw materials; use a cold heading machine to extrude such as figure 1 Clutch pressure plate rivets shown.

[0022] The second step is to quench the rivets of the clutch pressure plate.

[0023] Such as figure 2 As shown, the quenching treatment equipment includes a workbench with a water tank 1, a positioning column 2 capable of lifting movement is installed inside the water tank 1, and a positioning groove for placing a clutch pressure plate rivet 5 is opened on the top surface of the positioning column 2. A high-frequency inductio...

Abstract

The invention provides a manufacturing method of clutch pressure plate rivets and belongs to the technical field of vehicles. By means of the manufacturing method of the clutch pressure plate rivets,the problem that both an existing chromeplating process and salt bath process for the clutch pressure plate rivets generate a large quantity of contaminants and consequently the ecological environmentis affected is solved. The manufacturing method of the clutch pressure plate rivets sequentially comprises the following steps that 1, a steel plate or a steel bar is extruded by a cold heading machine to form the clutch pressure plate rivets; 2, the clutch pressure plate rivets are subjected to quenching treatment; 3, the clutch pressure plate rivets are subjected to sand blasting or shot blasting treatment; 4, tempering treatment is carried out, specifically, the clutch pressure plate rivets are heated to 270-300 DEG C and are air-cooled after being taken out; and 5, the clutch pressure plate rivets are soaked in antirust oil for antirust treatment. The process adopted for the manufacturing method of the clutch pressure plate rivets has the characteristics of small contaminant emissionand low energy consumption, and thus manufacturing of the clutch pressure plate rivets can be more environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and relates to a clutch pressure plate rivet, in particular to a clutch pressure plate rivet manufacturing method. Background technique [0002] Such as figure 1 The shown is a clutch pressure plate rivet, its technical requirements are smooth surface without burrs, corrosion resistance and wear resistance, and the surface hardness requirement is 48HRC~55HRC. The main manufacturing methods of the existing clutch pressure plate rivets are first cold heading and then surface chrome plating; or first cold heading and then salt bath treatment. The existing manufacturing method has the following deficiencies: 1. both the chrome plating process and the salt bath process will produce a large amount of pollutants, which will affect the ecological environment; 2. the chrome plating process and the salt bath process equipment investment cost is high; Large batches are produced at the same time, if the p...
