Driven by mechanical transmission or hydraulic system, the pipe is rotated or fixed, and pressure is applied to the end of the pipe using a mold to produce plastic deformation at room temperature, achieving processes such as pipe shrinkage or expansion. The shift cylinder and limit cylinder cooperate to achieve workstation conversion, which can alternately or simultaneously process the pipes of the two workstations.
It can achieve the processing of pipe fittings such as expansion, contraction, necking, bulging, and pier reinforcement. It can also process steel pipe ends into cup-shaped, trumpet shaped, and other irregular shapes. It can also perform operations such as chamfering, extruding convex platforms, and rolling.
