Problems solved by technology

In this process, the heating time of the equipment is long, the heating time of a single piece of the diaphragm spring cannot be guaranteed to be consistent, the measurement of the concentration of the baking color liquid is difficult, the number of operators is large, the labor intensity of the workers is high and the output is low, and the appearance and color of the finished diaphragm spring are inconsistent. Seriously affect product quality

Embodiment Construction

[0011] A kind of baking process of automobile clutch diaphragm spring, it is characterized in that: described process comprises the following steps:

[0012] a) sand the automobile clutch diaphragm spring;

[0013] b) Heating the clutch diaphragm spring after blasting in a mesh belt tempering furnace at a heating temperature of 200° C. to 230° C.; the heating temperature of the clutch diaphragm spring in step b is 40 to 60 minutes. Bake the surface of the clutch diaphragm spring to the desired color.

[0014] c) Leave the heated clutch diaphragm spring to cool;

[0015] d) Apply clear oil to the surface of the clutch diaphragm spring to prevent the surface of the diaphragm spring from rusting.

[0016] This process uses 50CrVA steel material to present different appearance colors at different temperatures. The higher the heating temperature, the darker the color, and the baking color temperature of the clutch diaphragm spring is lower than the tempering temperature of the ma...

Abstract

The invention discloses a baking finish technique for automobile clutch diaphragm spring, wherein said technique comprises the steps of slinging, heating in the mesh-belt temper furnace, cooling and oiling. With the technique mentioned above, the invention has the following advantages: 1) the temperature of the temper furnace is stable; the heating time for each clutch diaphragm spring stays the same, and the color of the baked diaphragm spring product also stays the same; meanwhile, the diaphragm spring is heated and baked according to certain requirement on color; 2) the production efficiency is enhanced and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile clutches, in particular to a color baking process of an automobile clutch diaphragm spring. Background technique [0002] The automobile clutch is an important part directly connected with the engine in the automobile transmission system, and the diaphragm spring is an important part in the general assembly of the clutch. Usually, the baking color of the diaphragm spring is carried out in an external heating salt bath furnace. The diaphragm spring after sand blasting is first placed in a 5% to 8% sodium nitrite solution, and a worker puts 2 to 4 diaphragms. The spring is on the special hook. The second worker puts the product on the hook in the baking color solution, waits for a few minutes, takes it out and puts it in clean water to cool. The third worker places and arranges the diaphragm spring into the frame after the product cools down. In this process, the heating time of the equipment is...
