Description

Technical Field

[0002] Product quality is the lifeline of an enterprise. Improving product processing quality is to strengthen the competitiveness and vitality of an enterprise. Failure to ensure product processing quality will weaken an enterprise's market competitiveness. Only by continuously improving processing technology can we improve and ensure product processing quality and have stronger market competitiveness. When processing the liquid hole of the TM157 column jack outer cylinder of a hydraulic support used in mines, the liquid hole is designed to be a deep hole on the pipe wall, and a hole is drilled from the outside of the cylinder wall to the inside of the pipe at a 90° angle 30 mm from the pipe mouth (such as Figure 1 As shown), the outer wall of the pipe is blocked by plugging welding (as shown Figure 2 Although this method facilitates hole processing, long-term use by mining companies has led to frequent leakage problems at the points where the cylinder's outer diameter is drilled through and where welding is blocked due to excessive pressure. Repairs at these points require welding, creating a high risk of underground operations and requiring the removal and replacement of the jack column and the lifting of the well for repairs, significantly impacting the mining company's productivity.
