Surface wear-resistant layer of spiral shaft for electronic glass and processing method

Abstract

The invention discloses a processing method of a surface wear-resistant layer of a spiral shaft for electronic glass. The processing method comprises the following steps: 1, a spiral shaft to be processed is heated to 700-800 DEG C; 2, a plasma spray gun moves around the to-be-machined spiral shaft, and alloy powder is sprayed to the machined part of the heated to-be-machined spiral shaft; and 3, after the sprayed spiral shaft is cooled, a wear-resistant layer is formed on the surface of the spiral shaft. By the adoption of the process treatment method that plasma flame spraying is matched with workpiece preheating, the problem that after a high-temperature tungsten carbide coating encounters a wear-resisting layer base body, the size of crystal particles is not uniform due to rapid cooling is solved, the crystal structure generated through the process method is more stable, the surface is smoother, a compact wear-resistant metallurgical bonding layer is formed, the hardness reaches about 60 HRC, and the service life of the spiral shaft is prolonged.

Description

technical field [0001] The invention belongs to the technical field of wear-resistant layer coating, in particular to a wear-resistant layer on the surface of a spiral shaft for electronic glass and a processing method. Background technique [0002] Screw feeder is a commonly used feeding device in the glass industry. It is usually composed of driving device, head section, middle section, tail section, head and tail bearings, feeding and discharging device, etc. Compared with other conveying equipment, screw feeder , has the advantages of small cross-sectional size of the whole machine, good sealing performance, stable and reliable operation, and easy maintenance. The screw is the main part of the machine, which consists of a shaft and a screw blade welded on the shaft. The helical blade is the same as the thread, and can be divided into left-handed and right-handed. There are many types of spiral blades, and the most common one is the solid spiral, which is widely used. I...

Problems solved by technology

In the prior art, the surface material of the spiral blade is made of pure carbon steel or stainless steel, and the surface of the 1Cr13 movable blade is added, but the surface quality of the surfacing welding is uneven, uneven, and the part is easy to fall off, especially the fallen impurities have a negative impact on the quality of the glass product. to seriously affect
