Embodiment Construction

[0014] Depend on figure 1 It is known that it is the Gpon optical network device for optical communication of the product of this embodiment. Its production process is:

[0015] 1. Take: 88 parts of stainless steel powder; 5 parts of wax, 2.2 parts of polypropylene, 6.3 parts of low-pressure polyethylene, 4.3 parts of thermoplastic elastomer; first add stainless steel powder and wax to the high mixer, stir at 600-650rpm at a low speed, and heat to Add polypropylene, low-pressure polyethylene and thermoplastic elastomer at 60-65°C, mix and continue to stir and heat, so that the temperature is controlled at 170-200°C, and the time is controlled at 20-30 minutes. After discharging, cut the mixed material into pieces, cool, Broken, bagged, and stored for later use;

[0016] 2. Injection molding: The above-mentioned mixed materials are injected into the blank by the injection molding machine through the mold. The technical conditions are: the mold temperature is controlled at 35...

Abstract

A Gpon optical network component structural part comprises the following steps of (1) material preparation, (2) injection molding, (3) extraction and (4) sintering, wherein the materials of the Gpon optical network component structural part are prepared by weight. Due to the fact that actual cutting does not exist, the materials are saved; the size precision and surface roughness of a connector are greatly improved, a decisive function is achieved on prolonging service life of the Gpon optical network component structural part, and the size precision can be controlled within a range of 0.05mm. The follow-up assembling efficiency is improved by more than 70%, and the method is superior to other manufacturing methods.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, in particular to a structural part of a Gpon optical network device produced by powder metallurgy technology. Background technique [0002] A Gpon optical network device structure 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 the production proce...
