AI Technical Summary
In existing flame tube structures, welding deformation control is difficult, material utilization is low, parts cost is high, the small support surface of welding fixtures leads to complex assembly, and the processing efficiency of forging blanks is low.
The flame tube structure is divided into an outer ring and an inner ring. Thick plate stamping blanks are used for processing. The weld seam positions are reasonably designed and connected by electron beam welding. The rear section of the inner ring is processed using a ring forging blank. The blank size is determined by CAD design and stamping is performed.
It effectively controls welding deformation, improves material utilization, reduces tooling costs, simplifies the assembly process, improves processing efficiency, and ensures the accuracy of welded parts.
