Hydraulic prop roller surface plasma surfacing welding machine

Abstract

The invention provides a hydraulic prop roller surface plasma surfacing welding machine which comprises a plasma welding gun, a workpiece turntable case, an X-axis transverse moving device, a Y-axis longitudinal moving device, a Z-axis lifting moving device, a powder feeder, a swinging device, a frame cross beam, machine frame double columns, an equipment base, a movable tailstock, a shading screen, an electric control cabinet and a power integrated cabinet. High-power plasma arc is utilized for melting alloy powder, a plasma surfacing welding process is adopted to replace a high-pollution chromium electroplating process, compared with laser cladding, the machine has the advantages of being low in investment, low in operation cost, easy and convenient to operate and wide in surfacing welding material range, has great application potential in the coal machine remanufacturing field, and effectively solves the problem of repairing the outer surfaces of a waste pillar plunger and a middlecylinder by the most economical means.

Description

technical field [0001] The invention belongs to the technical field of electromechanical equipment, and in particular relates to a plasma surfacing machine for hydraulic prop roller surface for coal machine remanufacturing and plasma surfacing. Background technique [0002] The hydraulic pillar plunger and the outer surface of the middle cylinder used in coal mines, the electrochrome plating process is used to solve the anti-corrosion and wear-resistant requirements in the prior art, but the electrochrome plating process causes serious pollution, which is now restricted by the national environmental protection. At the same time, the electroplated chrome coating is thin and corrosion-resistant The performance is not ideal. In order to prolong the service life of the pillar plunger and the outer surface of the middle cylinder, reduce the production cost of the enterprise, and repair the waste pillar plunger and the outer surface of the middle cylinder, a laser cladding process ...
