Problems solved by technology

[0004] (1) The processing technology of U-shaped open-hole niobium tube is complicated, there are many processes, and the product quality and consistency are not easy to guarantee
[0005] (2) The hole where the U-shaped niobium tube and the electrode match needs to be sealed by solder, which is very easy to cause air leakage
[0006] (3) The small hole at the bottom of the U-shaped niobium tube is easy to be skewed, which affects the straightness of the assembled electrode
[0007] (4) The surface of the U-shaped open-hole niobium tube, especially the section, is uneven and smooth
[0008] (5) Semi-automatic production, the efficiency is not high
[0009] (6) The price of raw material niobium tube is high

Abstract

The invention relates to a method for manufacturing an H-shaped sodium lamp niobium tube. After a niobium filament is straightened, the niobium filament is cut to be 12mm-16mm, then the surface of the niobium filament is subjected to polishing treatment, the niobium filament is placed between a first punching mold and a second punching mold, and after punching, the H-shaped sodium lamp niobium tube is obtained through automatic blanking. Compared with the prior art, a high-accuracy installation mold and a high-precision deep-punching device are specially customized, so that the product quality is guaranteed; the processing technology is relatively simple and adopts few procedures, the product quality and consistency are easy to guarantee, fully-automatic production is realized, and the efficiency is high; and an advanced data control system is equipped, and niobium zirconium filament materials can be selected and optimized with the adoption of a material design theory.

Description

technical field [0001] The invention relates to a method for manufacturing a niobium tube for a sodium lamp, in particular to a method for manufacturing a niobium tube for an H-type sodium lamp. Background technique [0002] High-efficiency sodium lamps are energy-saving and environmentally friendly products recommended by the state, and are also the development direction of light source companies at home and abroad. High-efficiency sodium lamp series products have high luminous efficiency and are used for urban road lighting, industrial and mining enterprise site lighting, shopping mall lighting, etc. The lamp emits bright yellow light, has a certain fog-permeable light color, high reliability and high efficiency. The niobium tube is a key component of the sodium lamp product. The connecting electrode of the niobium tube is hermetically sealed with the ceramic tube, and the quality directly affects the life of the lamp. [0003] The conventional niobium tube is designed a...
