A specialized piece of metalworking equipment designed for forming dovetail collas—a type of mechanical connection component with a trapezoidal (dovetail-shaped)cross-section.The machine integrates processes like material feeding,precision cutting,bend- ing,and shaping to  produce collars with accurate dimensions and  uniform dovetail strucures.Its core function  is to ensure the  colars fi tightly with matching dovetail grooves,providing high stabilty,load-bearing capacity,and resistance to disengagement in assembled  mechanical  systems.
