Problems solved by technology

[0002] At present, the valve core is basically made of copper material, but because the copper material has a large proportion, it will affect the balance performance of the tire, and the copper material is expensive and not environmentally friendly, so now people are trying to replace copper with aluminum alloy materials. However, due to the relatively loose crystal structure of aluminum alloy, the processing performance is not very good, so the processing of the existing technology is troublesome and the processing efficiency is very low.
Moreover, the manufacturing of the valve core in the prior art needs to go through cumbersome steps, including blanking, cutting the outer diameter of the head, cutting the outer diameter of the tail, drilling, reaming the inner hole, using dies to process external threads, and using tapping methods to process internal threads And product surface oxidation treatment, so there are more steps, more automatic lathes are used, and the production efficiency is relatively low

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the present invention is not limited to the following specific embodiments.

[0018] A method for manufacturing a valve core is made of aluminum alloy material, which includes the following steps:

[0019] (1) Blanking;

[0020] (2) Stamping and forming with a cold heading machine;

[0021] (3) Cutting with automatic lathe;

[0022] (4) Processing external threads;

[0023] (5) Machining internal threads;

[0024] (6) Product surface oxidation treatment.

[0025] The processing of the external thread in step (4) refers to processing with a thread rolling machine.

[0026] Said step (1) blanking refers to changing the original disc-shaped aluminum rod into a small section of a small section of aluminum column, which facilitates the stamping and forming of the cold forging machine in step (2).

[0027] The described step (2) is stamped and formed with a cold ...
