Semi Automatic Pipe Rounding Machine Three Roller Drive Compact Structure

Oil pressure power supply pipe rounding machine applying to greenhouse structure tube bending -- Brief introduction Pipe rounding machine is caused by the action of an external force, which causes the outer fiber of the steel plate to elongate and the inner fiber to be shortened to cause bending deformation (the middle fiber is not changed). When the radius of the cylinder is large, it can be rolled at normal temperature. If the radius is small and the steel plate is thick,
