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

Embodiment

[0015] 1) Blanking: The material is 409 stainless steel, with a thickness of 0.18mm and a width of 104mm. After punching, it is processed into a blank with a diameter of 18.8mm and a depth of 13mm. The number of one-time processing can be 3.

[0016] 2) Stretching: Put the blanks after blanking into the vibrating hopper, and then stretch them one by one through the punching machine to form a cylindrical shell with a diameter of 15.05mm and a height of 17mm, and process a diameter of 7.bmm at the bottom of the shell hole, and cut off the excess edge material on the upper part of the shell at the same time.

[0017] 3) Extrude positioning pins: symmetrically extrude two positioning pins with a diameter of 2 mm and a depth of 1.1 mm from the inside to the outside at a distance of 4 mm from the bottom of the housing.

[0018] 4) Degreasing and cleaning: Clean the lubricating oil used in the process. The method is to put the lamp head and sawdust together in the drum and roll for 1...

Abstract

The invention relates to a process technology for a lamp base of a bulb. The technology is implemented as follows: carrying out blanking; carrying out stretching; extruding a positioning pin; carrying out deoiling and cleaning; carrying out cutting to form an opening; pouring a glass cleaning solution; and carrying out cleaning and polishing. According to the invention, because of the stainless steel material, the mechanical strength of the lamp base is enhanced, thereby avoiding deformation during the production and transporting processes; the environment pollution is reduced and the production cost is lowered; and on the basis of the ball-milling polishing procedure, the extruding line on a stainless steel housing can be eliminated and defects caused by oxidization can be overcome.

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...
