Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel elbow processing equipment, and more specifically to an inner surface polishing device for stainless steel elbow processing. Background Art

[0002] In the piping system, elbows are pipe fittings that change the direction of the pipeline. According to the angle, there are three most commonly used elbows: 45°, 90° and 180°. In addition, according to the needs of the project, there are also other abnormal angle elbows such as 60°. The materials of the elbows are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. Among them, stainless steel has good corrosion resistance, high temperature oxidation resistance, good low temperature performance and excellent mechanical and processing properties. It is a common model of stainless steel elbows. In the process of stainless steel elbow processing, in order to avoid the internal debris and burrs of the stainless steel elbow affecting the use of the elbow, it is necessary to use a polishing device to polish the inner wall of the stainless steel elbow. The polishing machine drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed through an electric motor. Due to the joint action of the polishing disc and the polishing agent and the friction with the surface to be polished, the purpose of removing paint pollution, oxide layer and shallow marks can be achieved.

It is necessary to manually adjust the angle of the polishing disc and insert it into the elbow for polishing. The operation is time-consuming and laborious.
