Electric Sheet Metal Roll Forming Machines / Roll Former Machine
Components and Function
Coil Feeding Equipment Consists of one uncoiler with capacity of 3000kgs and its base. The mandrel can expand or shrink. With separate button to make the mandrel roll
Guiding Equipment Adopting guiding bar and sliding block to control the width and position of the steel sheet. The coil is guided in the correct position and passed to the roll forming equipment.
Roll forming system The main frame of machine is welded separately and the outside wall is connected by screw after being roto-blasted on the surface. The rollers with quenched treatment after being machined by the exact machining tool.
Hydraulic Station Supplies the initial power to the cuter through a closed oil tank. It is off without cutting, which can save the power.
PLC Control Panel Main parts imported from Mitsubishi. The operation is easy and steady and can be choose operation by manual or automatically.
