Embodiment Construction

[0014] Depend on figure 1 It is known that it is the optical communication sealing and welding type tee joint for optical communication of the present embodiment. Its production process is:

[0015] 1. Ingredients: take: 89 parts of stainless steel powder; 7.5 parts of wax, 2.6 parts of polypropylene, 7 parts of low-pressure polyethylene, 5.1 parts of thermoplastic elastomer; first add stainless steel powder and wax to the high mixer, stir at 600rpm at a low speed, and heat to Add polypropylene, low-pressure polyethylene and thermoplastic elastomer at 65°C, mix and continue stirring and heating, so that the temperature is controlled at 200°C, and the time is controlled at 20-30 minutes. After discharging, the mixed material is cut into pieces, cooled, crushed, and bagged , store for backup;

[0016] 2. Injection molding: The above-mentioned mixed materials are injected into a blank by an injection molding machine through a mold. The technical conditions are: the mold temper...

Abstract

The invention discloses an optical communication seal welding type T-junction. A method for preparing the optical communication seal welding type T-junction comprises the following steps of blending materials in part by weight, performing injection molding, extracting and sintering. Before sintering, burrs are soft and can be easily removed, so that the long-standing, big and difficult problem that the burrs are hard to remove is solved. The dimensional accuracy and rough surface of the product are greatly improved to play a decisive role in prolonging the service life of the T-junction, the subsequent assembly speed and efficiency is improved by over 70 percent, and the raw materialutilization rate is over 99 percent. More than 3,000 T-junctions can be produced by a double-cavity mould daily.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, in particular to a manufacturing process for producing optical communication sealed and welded tee joints using powder metallurgy technology. Background technique [0002] Sealed and welded tee joints 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 of...
