A precision forging forming process for the lamp body of a high-power LED floor lamp

Abstract

The invention discloses a precision forging and forming technology for a high-power LED pin lamp body. The precision forging and forming technology comprises the steps of material preparing, blank preparing, outer cover forming, outer cover finish machining, inspecting, cup body forming, cup body finish machining, inspecting, lamp body press-fitting, surface treating and final inspecting; an aluminum alloy bar is cut and forms blanks through precision forging, an outer cover blank body and a cup body blank body are obtained through numerical control finish machining and then are assembled in a press-fitting mode through an automatic press-fitting machine, and finally the LED pin lamp body is obtained. According to the precision forging and forming technology, the cup body blank and the outer cover blank are respectively obtained through pressure casting, then form the cup body blank body and the outer cover blank body respectively through numerical control finish machining and form the lamp body through interference assembly in a press-fitting mode, then the anodic oxidation surface treatment is carried out on the lamp body, and cooling fins arranged on the periphery in a surrounding mode facilitate heat dissipation of the lamp body; the structure is simple, assembly is fast, and the service life is long; the surface quality problems of the high-power LED pin lamp body caused by gas lines, cold shut and sand holes can be solved completely, and the production cost can be lowered.

Description

technical field [0001] The invention relates to the technical equipment field of a high-power LED lamp, in particular to a precision forging forming process for a lamp body of a high-power LED floor lamp. Background technique [0002] With the development of science and technology, high-power LED lighting fixtures are used in various lighting fields, especially in outdoor night lighting, such as LED floor lamps, which are inserted into the ground through pins, and the upper lamp body plays a lighting role , the cost of LED consumables for lighting has been gradually reduced, and its performance has been further developed. Compared with traditional light sources, it has advantages in service life, start-up time, stability, safety, environmental protection, etc., so it is widely used and used in individual lighting fields. It completely replaces the traditional light source. [0003] The lamp body of high-power LED floor lamp is usually made of aluminum alloy material, which ...

AI Technical Summary

Problems solved by technology

[0003] The lamp body of high-power LED floor lamp is usually made of aluminum alloy material, which is formed by one-piece die-casting and undergoes anodic oxidation surface treatment; the defects of the existing technology are: unreasonable structural design, poor heat dissipation performance of lamps, which seriously affects the service life of lamps; die-casting The lamp body produced by molding is prone to defects such as air marks, cold shut, sand holes, etc., which seriously affects the surface quality of subsequent anodized products, and the pass rate is low; high
