Four-roll plate bending machine

A coil bending machine is a device that uses working rolls to bend sheet material into various shapes, such as cylindrical and conical pieces, and is a crucial processing equipment. The working principle of the coil bending machine involves the application of external forces like hydraulic and mechanical pressure to move the working rolls, thereby bending or rolling the sheet material into the desired shape. Depending on the rotational movement and position changes of the working rolls of different shapes, it can produce components like elliptical pieces, curved pieces, and cylindrical pieces.
