The tube forming machine is a forming equipment for expanding, necking and contracting pipes under normal conditions. It is controlled by an integrated touch screen. The use of different molds can be achieved to pipe expansion, necking, shrink tube, drum, pier reinforcement, and according to user requirements, decided to use manual, inching or automatic processing. The utility model is mainly composed of a mail box, an automobile body, a slide block, a main oil cylinder, a limit oil cylinder, a pressing oil cylinder, a shifting oil cylinder, an axial positioning oil cylinder and an axial positioning contact iron.          through the tube type throttle valve is arranged in the main cylinder loop, which can adjust the working speed of the main cylinder; setting superposition type check valve in the pressing cylinder loop, can not guarantee loose mold clamping process; shift cylinder, limit superposition type bidirectional throttle valve are set up a oil cylinder, cylinder axial positioning loop, bidirectional motion speed adjustment of the cylinder. Wherein, the displacement oil cylinder and the limit oil cylinder are combined with a converting station, so that the working position can be conveniently converted and accurate, and the processing quality of the pipe fittings can be ensured.
