Problems solved by technology
At present, the clutch housings are all made by sand casting, but there are several disadvantages in the clutch housings made by sand casting.
First, due to the difference in metal solidification shrinkage, the shell wall thickness of the casting is uneven; second, there are defects such as shrinkage cavities and blisters on the surface of the casting; third, the surface of the casting is rough and the surface processing is difficult
Such a clutch housing is likely to make the motor balance deviation too large to generate noise and vibration, and at the same time increase the wear of the copper-based oil bearings at both ends of the motor, thus affecting the service life of the starter
There are so many safety hazards, we have to improve the existing clutch

Embodiment Construction
[0018] The accompanying drawings show a schematic view of the overall structure of the present invention, and the relevant details and implementation methods of its embodiments will be further described below in conjunction with the accompanying drawings. The manufacturing process of this kind of clutch housing is characterized in that its process steps are as follows: first, the iron plate is blanked into a disc shape, because the cross section of the housing 1 is close to a circle, which is convenient for subsequent stretching work, and then it can be cold state, use a hydraulic press to stretch the iron plate according to the octagonal outer casing convex-concave mold that has been designed, and the octagonal outer casing forms two pairs of symmetrical arc-shaped outer walls, and then process it with a lathe to remove excess material to the casing 1 Design dimensions (such as figure 1 , 2 shown), and then position and weld the four positioning pins 2 to the center of the i...

The present invention relates to improved technological process of stretching clutch casing. The technological process includes the following steps: blanking iron plate, stretching in a octangular mold, turning in a lathe to obtain casing in the design sizes, welding four locating pins inside the casing, forming locating hole and final welding the bottom plate to the casing. The process of the present invention can obtain clutch casing with even wall thickness and smooth surface.
Description
technical field [0001] The invention relates to an invention of a clutch housing stretching process. Background technique [0002] Clutches are widely used in the automobile industry. The starting, running, and stopping of automobiles are inseparable from the help of clutches. Therefore, the improvement and invention of clutches have attracted much attention. At present, clutch housings are all formed by sand casting, but the clutch housings formed by sand casting have several disadvantages. One is that the shell wall thickness of the casting is uneven due to the difference in the amount of solidification and shrinkage of the metal; the other is that there are defects such as shrinkage cavities and blisters on the surface of the casting; the third is that the surface of the casting is rough and the surface processing is difficult. Such a clutch housing is likely to cause excessive motor balance deviation to generate noise and vibration, and will also increase the wear of th...
