Description

Technical Field

[0001] The invention relates to the technical field of steel structure part processing, in particular to an automatic grinding and chamfering method for steel structure parts, and in particular to an intelligent grinding and chamfering method for automatically generating grinding and chamfering information and an online program for steel structure parts. Background Art

[0002] Industrial finished parts are generally composed of multiple parts with relatively complex structures, which is particularly prominent in the steel structure industry and the construction machinery industry. For the steel structure industry, the grinding and chamfering of parts is an important guarantee for the welding and painting quality of steel structure industrial finished parts. The grinding process of parts is to eliminate impurities such as oxide slag, burrs, slag inclusions, etc. after cutting that affect the welding quality; the chamfering process of parts is to ensure that a uniform and complete paint film can be formed when the surface of the parts is painted, so as to meet the painting quality requirements; therefore, it is necessary to grind and chamfer steel structure parts.

[0003] At present, the grinding and chamfering of steel structure parts is completed by personnel using manual tools or using stand-alone equipment to assist in the operation. Both of the above methods require personnel with certain technical capabilities to operate, and the grinding and chamfering information must be marked on the surface of the parts in advance, or a grinding and chamfering processing program must be formed after offline programming before the operator can complete the grinding and chamfering process. The above traditional operation methods are not only prone to errors, but also difficult to ensure the reliable and stable quality of the grinding and chamfering delivery, which ultimately affects the quality of welding and painting. In addition, it also requires a large number of operators, which is not conducive to controlling the overall cost. At the same time, it poses a greater risk to the occupational health of the operators, which is not conducive to the high-quality development of the enterprise.

[0004] Therefore, it is of great practical significance to develop a method for grinding and chamfering steel structure parts with good grinding and chamfering quality stability, high operating efficiency, low cost and no dependence on the operator's level. Summary of the invention

[0005] Due to the above-mentioned defects in the prior art, the present invention provides a method for grinding and chamfering steel structure parts with good grinding and chamfering quality stability, high operating efficiency, low cost and no dependence on the operator's level. Specifically, it is an intelligent grinding and chamfering method that automatically generates grinding and chamfering information and online programs for steel structure parts. The method can reduce the input of operators, ensure stable delivery of operation quality, reduce occupational health risks, reduce the comprehensive production cost of enterprises, realize intelligent production, and solve the current defects of grinding and chamfering quality of steel structure parts relying on the operator's level, poor quality stability, low operating efficiency and high cost.
