Anti-extrusion ring precision opening machine
Figure 1 shows the anti-extrusion ring for single hydraulic metal pillars in coal mines. The material is polyoxymethylene. This piece is a falling plastic ring, which is difficult to position and clamp, the angle is not easy to guarantee, and the opening is difficult. In the past, with manual opening, the quality did not meet the requirements, and it could not meet the production needs. In response to this problem, engineers and related personnel have repeatedly studied and improved the opening process, and designed and manufactured the anti-extrusion ring precision opening machine. The production structure proves that the machine has simple structure, strong practicability and convenient operation. Product quality and output are very popular with workers.
