A diamond drill bit brazing device

Abstract

The invention discloses a diamond drill brazing device which comprises a pressurization cylinder, a clamping cylinder, a pressurization rod, heating electrodes and a graphite electrode. The pressurization cylinder and the clamping cylinder are fixed on the same base, the pressurization cylinder is arranged vertically, the clamping cylinder is arranged horizontally, the heating electrodes are respectively fixed at the fixed end of the pressurization cylinder and the movable end of the clamping cylinder, the two heating electrodes can be matched to clamp and fix the graphite electrode and a diamond drill rod through the sliding end of a sliding clamping cylinder, the pressurization rod is fixed at the movable end of the pressurization cylinder so as to adjust the position of the movable end of the pressurization cylinder, the pressurization rod can perform pressurization on the graphite electrode, and insulators are arranged at the positions where the heating electrodes and the pressurization rod for claming and fixing the graphite electrode are connected with the pressurization cylinder or the clamping cylinder connected with the heating electrodes and the pressurization rod. The diamond drill brazing device is simple, low in manufacturing cost and maintenance cost, capable of obtaining diamond drills with good welding strength and rigidity, short in welding and heating time and high in welding processing production efficiency.

Description

technical field [0001] The invention belongs to the technical field of solder for metal brazing, in particular to a diamond drill bit brazing device. Background technique [0002] The diamond drill bit for optical fiber ferrule is a kind of superhard tool used to process the fast docking ceramic plug of optical fiber cable for communication. With the continuous progress of optical fiber communication technology in recent years, the application of optical fiber fast docking plug is becoming more and more extensive, and the demand continues to increase. The diamond drill bit for optical fiber ferrule is one of the important processing tools, and its performance and cost are directly related to the cost of optical fiber fast connectors. However, the processing technology of diamond drills has been blocked by developed countries for many years, and the use of products has always been dependent on imports. [0003] The fixing of diamonds includes mosaic wrapping, welding and bon...

Problems solved by technology

2. The solder layer at the welding joint is thin, because this type of solder is mostly a material with high plasticity, and an excessively thick solder layer will cause slight deformation of the tool when it is used, thus affecting the life of the tool

Too high and too long heating time will cause diamond graphitization, which will seriously affect the use effect of the tool

4. The positioning of the diamond must be accurate. Diamond is the hardest substance in nature and it is difficult to process. If the positioning is not accurate, the subsequent processing will be more difficult, and diamonds with larger particles are also required, so a lot of waste will be generated.
