Production process of metal gear shifting ball head

Abstract

The invention discloses a production process of a metal gear shifting ball head and belongs to the field of gear shifting ball heads. The production process comprises the following steps of die casting, wherein after an aluminum alloy ingot material is molten, a part base material is formed through die casting formation; machining, wherein machining treatment is conducted on the part base materialthrough a CNC process; polishing, wherein mirror polish treatment is conducted on the surface of a part; cleaning, wherein the polished part is cleaned; copper plating, wherein copper plating treatment is conducted on the surface of the part; polishing, wherein high-glossiness polishing treatment is conducted on the surface of the part obtained after copper plating treatment; cleaning, wherein the part obtained after high-glossiness polishing treatment is cleaned; and surface electroplating and spraying process treatment, wherein copper plating, nickel plating and chrome plating are sequentially conducted on the surface of the part, and finally, painting treatment is conducted. According to the production process, the gear shifting ball head is formed by conducting die casting on the aluminum alloy ingot material; after surface copper plating is completed, polishing and electroplating treatment are conducted; wear resistance and temperature resistance of the gear shifting ball head are improved; and in addition, the metal gear shifting ball head is recyclable, and the problem that when a plastic material is adopted, the environment is polluted is avoided.

Description

technical field [0001] The invention relates to a manufacturing process of a metal shift ball head, which belongs to the field of shift ball heads. Background technique [0002] The shift ball head is a part used for decoration and gear display in the shift handball. At present, plastic material is used as the base material, and then the surface is processed by spraying and electroplating. Due to the poor strength and temperature resistance of plastic materials , so that in actual use, when subjected to a large extrusion force, the shift ball will be deformed, which will affect the use; and the surface of the plastic shift ball will be worn after a period of use, which is not beautiful enough. Under extreme weather conditions, the plastic shift ball head is greatly affected by the alternation of cold and heat, causing it to deform or even fall off. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a manufacturing ...
