Abstract

Aiming at the problems of low efficiency during large-area coating, high labor intensity and poor uniformity caused by manual operation of an electric spark welding gun, the invention provides a pipe fitting automatic electric spark treatment device and method and belongs to the technical field of mold and casting surface defect restoration. The treatment device comprises a main mobile platform, a rotary chuck and a control system. The rotary chuck is connected with one end of a to-be-treated pipe fitting and arranged on the main mobile platform. An electrode of the welding gun makes contact with the outer surface or the inner surface of the to-be-treated pipe fitting. The treatment method comprises the steps that the welding gun is controlled to conduct electric spark treatment; meanwhile, the control system controls the rotary chuck to drive the to-be-treated pipe fitting to rotate; when the to-be-treated pipe fitting rotates by a set number of laps, the main mobile platform is controlled to move by a set stepping distance in the axial direction of the to-be-treated pipe fitting; and the steps are repeated till the discharging point of the electrode covers the outer surface or the inner surface of the to-be-treated pipe fitting. By adoption of the pipe fitting automatic electric spark treatment device and method, electric spark automatic treatment on the outer surface or the inner surface of the pipe fitting is achieved, complete coating is achieved, and the coating uniformity is good.

Description

technical field [0001] The invention relates to an automatic electric spark processing device, in particular to an automatic electric spark processing device and a processing method for pipe fittings, and belongs to the technical field of repairing surface defects of molds and castings. Background technique [0002] Electrospark deposition is a widely used surface defect repair technology for molds and castings. It is characterized by low equipment prices and high manual operation flexibility. The electrode materials used in EDM are generally metals and alloys such as hard alloys, stainless steel, and aluminum. However, the characteristics of manual operation of the electric spark welding torch also lead to low efficiency, high labor intensity and poor uniformity when coating a large area. Automated coating units are of great advantage when protective coatings need to be deposited over large areas using electric spark discharge. [0003] Coating thermal barrier, corrosion-...
