Problems solved by technology

[0002] The electromagnetic coil groove of automobile air conditioner clutch is obtained by direct lathe processing of forged blank or bar stock. The traditional hot forging or bar stock processing technology produces low raw material utilization rate, large energy consumption and large machining allowance, resulting in high blank cost and low production cost. low efficiency
Among them, the electromagnetic coil slot after forging not only has a large machining allowance due to the die, but also the die head makes the bottom of the electromagnetic coil slot arc-shaped, so the position of the coil is not suitable, which will have a certain impact on the future suction.
like figure 1 As shown in , the bottom 5 of the coil slot is arc-shaped. If deep processing is required, additional processing steps are required, which increases the cost

Embodiment Construction

[0012] The present invention as figure 2 shown.

[0013] The electromagnetic coil groove of the automobile air conditioner clutch includes the electromagnetic coil groove 1, the inner wall 3, the outer wall 2 of the electromagnetic coil groove 1 and the plane 4 at the bottom of the electromagnetic coil groove are all formed by one-time cold extrusion.

[0014] Wherein the bottom of the electromagnetic coil slot is a plane.

[0015] In order to ensure the quality of the cold extrusion process, the key control of each process:

[0016] 1. Forging pre-forming should leave a suitable margin for cold pressing, mainly the ring groove (coil) margin, to prepare for the subsequent precision forming;

[0017] 2. The heat treatment (annealing) process adjusts the structure and hardness of the forged billet, and ensuring a good internal structure and appropriate hardness is the key preparation for the cold extrusion process;

[0018] 3. The phosphorus saponification process is the mos...

Abstract

The invention provides an electromagnetic coil groove of an automobile air-conditioning clutch. The inner wall, the outer wall and the bottom of the electromagnetic coil groove are all formed at one time in a cold extrusion manner; the bottom of the electromagnetic coil groove is a plane. The electromagnetic coil groove provided by the invention is precisely formed at one time in the cold extrusion manner, further processing is not needed, the resource is saved, the cost is lowered, and the production efficiency is improved. As the bottom of the electromagnetic coil groove is a plane, coils can be easily flattened when being assembled, and the electromagnetic sucking force of the coils is increased.

Description

technical field [0001] The invention relates to parts of an automobile air conditioner, in particular to an electromagnetic coil slot for an automobile air conditioner clutch. Background technique [0002] The electromagnetic coil groove of automobile air conditioner clutch is obtained by direct lathe processing of forged blank or bar stock. The traditional hot forging or bar stock processing technology produces low raw material utilization rate, large energy consumption and large machining allowance, resulting in high blank cost and low production cost. low efficiency. Among them, the electromagnetic coil groove after forging not only has a large machining allowance due to the die, but the die head also makes the bottom of the electromagnetic coil groove be arc-shaped, so that the placement position of the coil is not suitable, which will have a certain impact on the future suction. Such as figure 1 As shown in , the bottom 5 of the coil slot is in the shape of an arc. If...
