A manufacturing process of a three-way joint for optical communication

Abstract

The invention provides a manufacturing technique of a T-junction for optical communications. According to the manufacturing technique of the T-junction for the optical communications, materials are measured by weight, and the manufacturing technique of the T-junction for the optical communications includes the following steps of (1) charge mixture, (2) injection molding, (3) extracting, and (4) sintering. According to the manufacturing technique of the T-junction for the optical communications, due to the fact that materials are not cut actually, the materials are saved, the T-junction is formed for one time with only three workers, and few procedures are needed. If parts are picked up manually, the yield of a two-cavity die is increased to 4200 per shift, and the yield of a four-cavity die is increased to 8000 per shift. If the parts are picked up by mechanical arms, the yield of the two-cavity die is increased to 5000 per shift, the yield of the four-cavity die is increased to 10000 per shift, and production efficiency is improved to a large extent. Burrs are soft before the T-junctions are sintered and can be removed easily, and thus the problem that the burrs are difficult to remove is solved.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, in particular to a manufacturing process for producing tee joints for optical communication using powder metallurgy technology. Background technique [0002] A product with a round and square tube body used in the optical communication industry, such as figure 1 , The material is stainless steel. The processing method used before is machining. When processing by car, there are about 10 processes, 10 workers are used, and the output per shift is about 1,000. Since the material used in the lathing process is a solid bar, the weight before processing is three times the weight of the finished product after processing, and the waste of material is serious; the processing accuracy of mass production is unstable, and the burrs generated by lathe processing are a problem that plagues the entire industry, which is time-consuming. Laborious; many processes, high precision, difficult inspection o...
