Auto double head bending machine

It cold bending method is used to bend the tube at room temperature. It is more suitable for bending stainless steel tube, aluminum pipe and copper pipe because it does not need heating when bending with pipe bending machine. The commonly used cold bending method is rolling bending (rolling machine reel machine). Winding, bending, bending and bending are mainly introduced in this paper. In general, the bending radius of cold bending should not be less than 1.5 times the diameter of the tube. Because the tube has a certain elasticity. However, when the external force is applied to the bending is eliminated, the pipe will rebound to an angle, and there must be a certain amount of recoil in bending. The amount of spring back is related to the mechanical properties, wall thickness and bending radius of the pipe material. When the copper tube is bent, the spring back angle is about 2-5 degrees.
