Abstract

The invention discloses a method for improving flame cutting and blanking precision of a steel tube arch rib shell section base metal steel plate, which comprises the following specific blanking steps: step 1, selecting raw materials, determining the steps of the steel tube arch rib shell section base metal cutting and blanking method and corresponding raw material production equipment, and carrying out trial operation on the production equipment; step 2, lofting a steel plate, performing numerical control programming on a full-automatic numerical control flame cutting machine, compiling a running track of a cutting nozzle in a computer, and debugging related parameters; thirdly, before formal cutting, the cutting torch is made to run for one round in an idle mode according to numerical control programming, and the cutting running track is simulated; fourthly, the full-automatic numerical control flame cutting machine begins to conduct formal cutting, and after cutting is finished, four points of the shell section base metal steel plate are still not cut; the blanking and cutting precision of the steel pipe arch rib shell section base metal steel plate is improved, it is ensured that the blanking precision and quality of the steel plate are within the controllable range, and a foundation is laid for a series of subsequent machining and manufacturing of the steel pipe arch rib with the high precision requirement.

Description

Technical field [0001] The present invention belongs to the field of cutting and unloading technology, specifically relates to a method of improving the precision of steel pipe arch rib section base metal steel plate flame cutting cutting. Background [0002] Steel pipe concrete arch bridge steel pipe arch rib manufacturing precision requirements, processing difficulty, many processes and technical complexity, so in the steel structure processing of each process of the quality and precision control of the linear shape of the bridge has played a vital role, steel plate cutting as the first processing process of steel pipe arch rib manufacturing, which has a direct impact on the geometric dimensional accuracy and quality of a single cylindrical segment forming, and continues to affect the subsequent main chord pipe manufacturing, main arch rib unit manufacturing, assembly matching manufacturing processing accuracy, Therefore, the control of the cutting accuracy of steel plate cutti...
