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 Construction

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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 production process of a light bulb cap of a motor vehicle, in particular to the manufacture of a light bulb cap of a road motor vehicle. It belongs to the technical field of electric light source manufacturing. It includes the following steps: blanking, stretching, extruding positioning pins, degreasing and cleaning, cutting, glass pouring and cleaning and polishing. The above process adopted by the present invention improves the mechanical strength of the lamp cap due to the use of stainless steel material, and is not easy to be deformed during production and transportation; at the same time, environmental pollution is reduced and production costs are reduced; at the same time, the ball milling and polishing process can be used to eliminate the stainless steel shell. Extrusion lines on the body, and defects formed by oxidation.

Description

technical field [0001] The invention relates to a production process of a light bulb cap of a motor vehicle, in particular to the manufacture of a light bulb cap of a road motor vehicle. 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 disadvantages. 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 hold...
