AI Technical Summary
Traditional methods are difficult to efficiently process long, continuous variable cross-section pipes, especially in the absence of large equipment. Furthermore, the processing accuracy and efficiency are low, and it is difficult to guarantee coaxiality and smooth transition.
A multi-field composite local continuous bulging mold and system for irregularly shaped cross-section long pipes is adopted. Through segmented processing, local bulging is achieved using small equipment. Combined with water cooling and electric heating technology, a local current loop is formed for heating and bulging, and gas pressure is used for plastic deformation.
It enables high-precision, low-cost continuous variable cross-section long pipe processing, improves processing reliability and material utilization, reduces equipment requirements, lowers material yield strength risk, and ensures yield and dimensional consistency.
