Abstract

The invention provides overlaying equipment of a drilling tool for petroleum extraction. In the overlaying equipment, a set of powder spraying mechanism is additionally arranged on the basis of the conventional automatic control carbon dioxide welding machine, is arranged in parallel with a water-cooled welding gun for use and comprises a mounting plate, a powder box, a speed adjusting motor, an eccentric shaft, an upper sliding plate, a lower sliding plate, a discharge pipe, a powder spraying gun tube, an adjusting switch and an argon gas delivery nozzle. By adopting the overlaying equipment of the drilling tool for petroleum extraction, combination of carbon dioxide shielded welding and powder spraying facing can be realized to perform synchronous welding, so that the forming of a weld joint and the fusion depth of a welding wire and a parent metal are effectively increased, and the hardness of a welding layer is improved; and thus, the wear resistance of the drilling tool and the anti-friction quality of the drilling tool to a bushing are improved, and the service life of the drilling tool is prolonged by more than two times.

Description

technical field [0001] The invention relates to a surface treatment equipment for pipe materials, in particular to a surfacing welding equipment for drilling tools used in oil exploitation. Background technique [0002] With the rapid development of the oil drilling industry, more and more drilling tools are used for oil exploration, and the damage of drilling tools in drilling is also becoming more and more serious. The existing technology adopts plasma spray welding and carbon dioxide protected hard surface surfacing technology to form a layer of wear-resistant band on the vulnerable surface of the drilling tool, which plays a certain positive role in protecting the damaged surface of the drill pipe during drilling and drilling. . However, the weld seam used as welding surfacing has higher and higher requirements for the protection of the drill pipe, and the user has higher and higher requirements for the service life of the drill tool. Existing technologies can no longe...
