Embodiment Construction

[0013] Specific examples of the present invention are given below to further illustrate the composition of the present invention.

[0014] The invention discloses a hydraulic support column remanufacturing thread hole processing technology. After the threaded hole of the remanufactured column is internally resurfacing, the stainless steel layer is clad by laser technology, and the longitudinal and circumferential argon arc welding of the stainless steel sleeve is carried out. One piece, the thickness of the stainless steel layer is 0.6-4.0mm, and the inner hole is re-drilled later. After processing, the thickness of the stainless steel layer is 0.5-4.0mm, so that the surface layer of the parts and the surface of the substrate form a uniform, dense, smooth, anti-corrosion and anti-corrosion Grinding stainless steel layer to achieve its anti-corrosion, anti-corrosion and wear-resistant ability, that is, a stainless steel layer with a thickness of 0.5-4.0mm is formed on the surfac...

Description

[0001] technical field [0002] The invention belongs to the field of coal mine support technology research, in particular to a hydraulic support column remanufacturing process for column head threaded holes. Background technique [0003] The threaded hole of the column of the hydraulic support is a part of the liquid passage through the live column of the double telescopic column, which plays a key role in the action of the support. The threaded hole adopts the traditional drilling and tapping process in the new processing, without anti-corrosion treatment, and it is used underground after being connected with the rubber hose. Due to the long-term corrosion of various conditions such as water quality and pressure, it is difficult to remanufacture. Contents of the invention [0004] In order to make up for the defects of the prior art, the present invention provides a hydraulic support column remanufacturing thread hole processing process with good anticorrosion and wear ...
