Problems solved by technology

However, there are many defects in the lamp caps currently produced with steel strips, copper strips or aluminum strips.
On the one hand, because the surface of the steel strip, copper strip or aluminum strip is easily oxidized, the surface of the lamp holder needs to be electroplated or chemically treated during production, and the electroplating process consumes a large amount of harmful chemical materials, and at the same time produces a large amount of waste water, waste gas and waste residue
On the other hand, copper or aluminum is used as the material of the lamp holder, and the raw materials are relatively expensive, resulting in a higher cost of the lamp holder.
In addition, copper or aluminum lamp caps have low mechanical strength and are prone to deformation during production and transportation

Abstract

The invention relates to a technology for a bulb holder, comprising the steps of blanking, stretching, extruding a locating pin, de-oiling and cleaning, cutting, pouring, and polishing. According to the technology, because stainless steel material is adopted, the mechanical strength of the holder is improved, and the holder is not easy to deform during production and transportation; at the same time, the environment pollution is reduced, and the production cost is reduced; and in addition, the working procedure of ball-milling and polishing is adopted, so that extrusion lines on a stainless steel shell and the defect caused by oxidation are eliminated.

Description

technical field [0001] The invention relates to a technology of a light bulb base, in particular to the manufacture of a road motor vehicle light bulb base. It belongs to the technical field of electric light source manufacturing. Background technique [0002] At present, the shells used for the lamp caps of road motor vehicles are generally made of steel, aluminum alloy or brass, which are firstly stretched by blanking, nickel-plated, and then formed by cutting and pouring glass. The shells of the metal lamp caps used in the electric light source industry are made of ordinary carbon-structured cold-rolled steel strips, copper strips or aluminum strips, which has become the mindset of the industry. However, current lamp caps produced with steel strips, copper strips or aluminum strips have many drawbacks. On the one hand, because the surface of the steel strip, copper strip or aluminum strip is easy to oxidize, the surface of the lamp holder needs to be electroplated or ch...
