Welding clamp forming tool for header heat exchanger

A welding, clamping and forming tool for a header heat exchanger relates to the technical field of header heat exchanger processing, a positioning mechanism is mounted in an insertion hole in a fixing plate, a limiting mechanism is mounted on a main body plate, and the limiting end of the limiting mechanism corresponds to the positioning end of the positioning mechanism. The position of the central axis of the positioning mechanism coincides with the position of the central axis of the main body plate, the number of the positioning plates is two, and the two positioning plates are located on the two sides of the fixing plate correspondingly and are in contact connection; according to the welding, clamping and forming tool for the header heat exchanger, headers needing to be welded and clamped are limited through the limiting mechanism, the heights of the headers are uniform, the headers are positioned through the positioning mechanism, the headers are prevented from moving in the welding and clamping process,
