Structural description
The structure of the machine is a three roll symmetrical type, with the upper roll performing vertical lifting and lowering movements at the symmetrical center position of the two lower rolls. The two lower rolls rotate with each other through a screw and worm drive, and the output gear of the reducer meshes with the lower roll gear to provide torque for the rolled sheet metal. The machine is an integral structure, with the working and main transmission parts installed on a rigid welded base, which facilitates the installation and debugging of the machine.
