Multi-station Micro-shrink Vertical Expander Machine

This equipment is a fully automatic tube expanding equipment for the production of heat exchangers for air conditioning equipment. It is used to expand the hole, flaring and flanging of the tube heat exchanger. When expanding the tube, the expanding rod and the expanding ball enter the copper tube to expand it, so that the copper tube and the fin are closely attached to achieve higher heat exchange efficiency. The flaring allows the small elbow to be inserted into the nozzle for positioning, and the flange is used to accumulate solder at the welding port. Micro-shrinkage tube expansion refers to: fix the two ends of the copper tube and expand the tube to reduce the shrinkage rate of the copper tube by more than 2.5%.
