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

[0007] 1) Blanking: The material is made of 409 stainless steel with a thickness of 0.18mm and a width of 104mm. It is processed by a punching machine into a blank with a diameter of 18.8mm and a depth of 13mm. The number of blanks processed at one time can be 3.

[0008] 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 hole with a diameter of 7.5mm at the bottom of the shell , and at the same time cut off the excess edge material on the upper part of the shell.

[0009] 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.

[0010] 4) Degreasing and cleaning: Clean the lubricating oil used in the process. The method is to put the lamp head and sawdust toget...

Abstract

The invention discloses a production technology for the lamp holder of road vehicles, which comprises the following steps: blanking, stretching, extruding locating pin, deoiling, cutting, pouring and polishing. With the technology, since stainless steel material is adopted, the mechanical strength of the lamp holder is improved, and the lamp holder can not easy to deform during the transportation process; 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 the extruded ripple on the stainless steel shell and the defect caused by oxidation are eliminated.

Description

technical field [0001] The invention relates to a production process of a lamp cap used for an electric light source, in particular to a process for manufacturing a lamp cap of a road motor vehicle light bulb by using stainless steel materials. 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 holder needs to be el...
