Novel lamp arm and manufacturing technology thereof

Abstract

The invention discloses a novel lamp arm. The novel lamp arm comprises a resin decoration part and a copper pipe; the resin decoration part is arranged on the outer side of the copper pipe, a flat copper decoration part is arranged between the resin decoration part and the copper pipe, and a copper pipe decoration part is arranged on the side face of the copper pipe. the production process is simple, production cost is low, in-batch production efficiency is high, the environment-friendly requirement is met, occupied space during production is small, the wall thickness is uniform, mechanical performance is good, the lamp arm is high-end and bright in color, the arm cannot be rusty never, and the surface figure is more clear.

Description

technical field [0001] The invention belongs to the technical field of lamps, and more specifically relates to a novel lamp arm. At the same time, the invention also relates to a manufacturing process of a novel lamp arm. Background technique [0002] There are many structures of the lamp arms of the existing lamps, but most of them have obvious defects: (1) The first one is to electroplate a thin layer of copper on the outer surface after die-casting of iron alloy, with a thickness of about several microns to tens of microns. Anti-corrosion, although the lamp arm of this structure is low in cost, since there must be outlet holes at both ends of the lamp arm, and a pipe for passing the wire is provided in the middle of the lamp arm, so it is easy to be damaged in the pipe passing the wire. Corrosion and rust. In addition, the surface of the entire workpiece forms an uneven honeycomb shape, and the corrosion resistance is not high. The electroplating layer is easily damaged ...

Problems solved by technology

[0002] There are many structures of the lamp arms of the existing lamps, but most of them have obvious defects: (1) The first one is to electroplate a thin layer of copper on the outer surface after die-casting of iron alloy, with a thickness of about several microns to tens of microns. Anti-corrosion, although the lamp arm of this structure is low in cost, since there must be outlet holes at both ends of the lamp arm, and a pipe for passing the wire is provided in the middle of the lamp arm, so it is easy to be damaged in the pipe passing the wire. Corrosion and rust. In addition, the surface of the entire workpiece forms an uneven honeycomb shape, and the corrosion resistance is not high. The electroplating layer is easily damaged and peeled off. Generally, spots appear in 2-3 years. The aesthetics of the entire product is greatly reduced, and the quality of the product is poor. lower price

(2) The second type is die-cast copper parts. As an improvement to the first type of lamp arm structure, its advantages are: the corrosion resistance is significantly improved, the appearance and quality are better, and the grade is higher: but there are also obvious disadvantages: A hollow metal tube is used as the mold core, and a hollow channel is formed inside the metal tube, and threaded outlet holes are tapped at both ends of the tube to connect with other parts, and then a lamp arm made of brass is die-cast on the outside of the metal tube , the shape of the lamp arm can be varied, and the size and length are also different. Considering the design of the mold die-casting flow channel, the thickness of the lamp arm is greater than 4mm. Therefore, the cast lamp arm is heavier, the cost is higher, and the surface of the die-casting part is smooth Poor degree and flatness, poor light reflection effect, poor metal texture, most of the hollow metal pipes are pressed by iron and other metals, and they are still prone to rust, and rusty ash will still be discharged from the outlet hole, which will affect the decorative effect

[0003] In addition, the traditional iron and resin method is used to produce the lamp arm, which is not high-grade, easy to peel off paint and rust, and the paint is easy to be damaged, so its market share is relatively low.
