Description

technical field

[0001] The invention relates to the technical field of spinning forming of thin-walled curved surface components, in particular to a method for measuring the deflection angle of weld seams of thin-walled curved surface components formed by spinning of metal sheet tailored welded blanks. Background technique

[0002] Tailored welded blank spinning forming technology is a novel advanced manufacturing technology that welds several metal sheets of the same or different sizes, thicknesses, and materials into a tailor welded blank, and then performs integral spinning. The use of tailor-welded blank spinning forming technology to produce thin-walled curved components has significant advantages: the process tooling and molds are relatively simple, which greatly reduces the number of special process equipment, shortens the production preparation time and cost; compared with the traditional stamping + tailor welding Tailored welded blank spinning forming can overcome t...
