Welding line surface paint removing technology

Abstract

The invention relates to a welding line surface paint removing technology. The welding line surface paint removing technology comprises the steps that a coating thickness measurer is used for measuring the thickness of a paint layer at the welding line position of a to-be-machined component, and the first scanning parameter and the second scanning parameter of a laser device are set according to the thickness of the paint layer; the to-be-machined component is arranged on a machining platform to be clamped and positioned; the laser device conducts laser scanning on the paint layer at the welding line position of the to-be-machined component according to the first scanning parameter, and accordingly, an upper part of the paint layer at the welding line position of the to-be-machined component is removed; and the laser device conducts laser scanning on the paint layer at the welding line position of the to-be-machined component according to the second scanning parameter, and accordingly,a lower part of the paint layer at the welding line position of the to-be-machined component is removed. According to the welding line paint surface treatment technology, the technology is simple, operation is easy, greenness and environment friendliness are achieved, the technology of automatic operation of steering frame welding line paint removal treatment is conveniently achieved, a base material of a machined part cannot be damaged, and the welding line surface paint removing technology meets the lossless detection requirement; and meanwhile, energy needed for laser scanning processing is low, and the needed space is small.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a process for removing paint on the surface of a weld seam. Background technique [0002] Entering the 21st century, my country's rail transit is in the ascendant. As the most populous country in the world, in order to ensure an effective, fast and convenient transportation, rail transit has begun to appear frequently in our lives as a main trend. As an important part, the bogie is used to carry the vehicle, provide traction (power bogie), shock absorption, and its main function is to solve the guiding problem of the vehicle. Whether its structure is reasonable or not directly affects the running quality, power performance and driving safety of the vehicle. The rapid development of high-speed trains all over the world and the rapid development of modern urban rail vehicles are all closely related to the progress of bogie technology. One of the core technologies for the...

The paint remover has high paint removal efficiency, low corrosion, does not damage the surface of the object, and can be used at room temperature, but it is highly toxic, costly, and flammable

[0009] Existing laser paint removal mainly adopts carbon dioxide laser paint removal method, and scans multiple times with the same parameter. The thermal effect is large during processing, and it is easy to produce an oxide layer. In addition, the cost of carbon dioxide laser is high, and maintenance is troublesome. Carbon dioxide laser does not have optical fiber transmission, light guide system Complicated, with large volume and weight, it is not easy to install on the manipulator, and the weld seams of the parts to be processed are mostly curved surfaces, so the carbon dioxide laser is not suitable for paint removal of the parts to be processed
