Hydraulic entry car
The hydraulic entry car can move levelly and vertically, which is convenient for putting the steel coils to the decoiler.
The car sets one hydraulic lifting oil cylinder, four balance guide pillars.
Function: Hydraulic entry car is used to lift up and down, move forward and back to make it easy to loads the coils on decoiler. Hydraulic controls lifting, motor drives moving. The car will return back to the start position. It can also carry back the unfinished coils from decoiler.
Double head decoiler
◆Supporting steel rolls and uncoiling
◆It is designed with the double hydraulic movable structure
◆The hydraulic cylinders on both sides drive the landscape orientation movement
◆It is equipped with the brake devices and taper decoiler and the 400 hydraulic brake wheel.
◆Mechanical structure: the process is welded by steel plate and steel.

Press and pinch with side guide device
◆Two hydraulic cylinders controlled unwinding rubber roller lifting.
◆Cycloidal reducer BWY215-121 drive the running of steel coil.
◆ Hydraulic shovel head, hydraulic power shovel-head and feeding steel plates.
◆Structure: It is welding by steel plates and profiled bar
◆Equipped with side guide device,It is composed of the frame, guide roller, adjustment device, movable platform and multi-roller wheel
◆The vertical rollers on the both sides guide the sheet right into the slitter.
◆800-2000mm Both sides of guiding vertical rollers adjust by the motor drives the both ends of the screw. The adjusting width is: 800-2000mm
Four fold leveling machine (90KW DC)
◆It is composed of 15 working rollers, driving device, 2 pinch code rollers, 3 groups of supporting rollers and machine frame. Both sides of each rolling wheel is transmitted by needle pins, all are main driving rollers. Total it is 17 rollers ,the diameter of leveling roller is 125 mm, and the distance of leveling roller is 135mm,it is with supporting rollers
◆the function of supporting roller: make the even rollers receive the balanced force and reduce the friction of the leveling rollers
◆the working rollers use electric machine to adjust the upper and lower gap with 2 hand wheel to make sure the even quality.
◆Drive model: all the independent rollers and gear box are driven by 90kw DC control electromotor machine.
◆Automatic circulating lubrication system

Cutter
◆shear model: cut from up to down hydraulically which is cooperate with the signal direct from the encoder and shear automatically
◆Automatic control the shearing
◆Adopt gap adjusting design to cut the materials
◆Four-side cutter , the material is 6CrW2Si,and it can shear 6mm steel plate safely after heat treatment
Receive table
◆It length is 500-6000mm, set side guide stacking device.
◆Width adjustment: 800mm(min)-2000mm(max)
Hydraulic system
◆Ensure the using of every hydraulic parts
◆The working pressure of the hydraulic system is 6.3-16Mp
◆Hydraulic energy adopt the domestic high-quality brands
Electrical system
◆Standard electric cabinet for electric control
◆The whole line is centralized control.The main operating table has the function of length setting, digital display, automatic counting, high and low speed adjustment, manual feeding, automatic feed, continuous shear, fault alarm and so on.Adopt the servo control mode and PLC control mode , It is controlled by LCD screen with fixed-length cutting by codes and count automatically.
