2. Composed devices

Hydraulic coil car

        The car can move levelly and vertically, which is convenient for putting the steel coils to the un-coiler.

        It is driven vertically by hydraulic cylinder with 4 guide pillars.

        The level movement is driven by XWD2.2-63-121 cycloid motor.

Hydraulic de-coiler

        Supporting steel rolls and uncoiling.

        Hydraulic expand and shrink.

        With power to make the right and left running possible.

Hydraulic pinch and press and pre-leveling device

        This is composed of bottom-stand (frame), hydraulic pressing and guiding arm, coil opener, hydraulic shovel head device, hydraulic pinch and preliminary flattening device, power device, etc.

Head cutting machine

        Adopt double structures, a pressure loading device, can cut the 4mmX1250 steel plates.

Slitting machine

        Drive system consists of drive stand, 500 decelerator, 30KW frequency conversion control motor, the gear distribution box, coupler, connection shafts and cover.

        Main section is made up of base, fixed brackets, large slide block, 2 blade pivot (Φ160mm), movable brackets, slide block, the adjustment device of front and back of the brackets and the lifting device of blade pivot, supporting blades, isolating cover and rubber ring etc.

        The main section adopts manually move out the brackets which is very convenient to change the blades

Tension stand

        Consist of base, pre-dividing shaft, bracket, press shaft, hydraulic damp device and hydraulic shaft lifting the press down device.

Hydraulic recoiler

        Consist of base, bearing frame, recoiler shaft, the expansion device of hydraulic recoiling, the expanded recoiling plate, movable arm bearing, supporting 650 decelerator, 55KW frequency conversion control motor.

Hydraulic unload car

        The car can carry the dividing coils and lift up and down and is movable

Electrical control system

Hydraulic System
