Brief introduction of the 12x2000mm hot roll cut to length line

1.  V-Shaped saddle

◆It is used to load the coil, to prevent from damaging the car due to putting the coil into car directly.

◆It is one pair (two pieces), length 1000mm, width 480mm.

2.  Hydraulic entry coil car

◆Hydraulic coil car is composed of base, axle, wheels, bearing and guide rods, guide bushing, up-supporting seat, rolling wheel, hydraulic lifting cylinder and hydraulic motor.

◆Brief description:Hydraulic entry coil car carries and moves the steel coils to the uncoiler part, and lifts up the coils on the uncoiler doing uncoiling.

3. Decoiler:

◆Decoiler is a pair of taper-shaped uncoiling machine. It is composed of linear model base, frame, decoiler shaft, taper plate and hydraulic pushing device. One of the decoiler is equipped with the brake

◆When the coil car lift the steel coils and the coil diameter center is aim at the decoiler center . Two decoilers against tight the coils. The two decoilers can be centering independently ,also can centering together to loading the coils. When the coil is not in the production center, double decoiler can move together to left or right accordingly. When uncoiling, stop the brake and when stop running, start the brake

4. Press and pinch device

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

a.  Hydraulic pressing & guiding device is composed of hydraulic pressing and guiding arm, pressing and guiding wheel(cover by rubber), sprocket wheel, chain, accompany of motor, etc.

b.  Hydraulic shovel-head device is composed of shovel-head body, hydraulic shovel-head, balanced device for hydraulic shovel-head.

c.  Hydraulic pinch and preliminary leveling machine is composed of slide-stand, pinch roller(2pcs), hydraulic pinch device, 2pcs of pre-leveling rollers, hydraulic pre-leveling device, etc.

d.  Power device for pinch is composed of AC speed control motor, decelerator, gear distributor case, clutch, one group spindle etc.

◆Brief introduction: the steel coils on the decoiler through the press arm to press down. Cut off the belts and running the press wheel by the motor to make the steel head moving forward. Expand the Hydraulic shovel-head device and adjust the balance cylinder to control the height of the shovel-head. Once receiving the steel head, lift up and down the hydraulic head-leveling device to press and straighten the head to ensure the head can pass the press and pinch device smoothly. Adjusting the pre-leveling 1 roller and 2 roller to feed the pre-leveled sheets to roller table.

5. Roller table

◆It is composed of frame, rollers, supporting plate and bearing seat.Width: 2000mm, length :2m  Roller diameter: 140mm, supporting bearing 212: 8pcs

◆Brief description: The roller table is used to feed the sheets and the roller design is to prevent the sheets scratching the table directly and protect the sheets.

6. Side guide device

◆Side guide device is composed of the linear model base, movable plate, adjustment device and stand rollers.

◆Brief introduction: side guide device is to guide the sheets from pre-leveling device and centering to the slitting machine to avoid left or right deviation.

7. Straightener

◆It makes uneven steels even and guide them to the right following processing and shears the material with fixed-length and packs with fixed-number.

◆It is composed of 11working rollers, driving device, 2 pinch code rollers and stand. Both sides of each working roller is transmitted by spherical roller bearings and both are the main power roller.

◆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 4kw electric machine through turbine decelerator to adjust the upper and lower gap to make sure the flat quality.

◆Drive model: all the independent rollers and teeth round box are driven by 110kw direct-current electric machine, and decelerated by 900 reducer ,and consists of teeth round distribution box and all-round shaft connection and hydraulic brake .etc

◆the processing of rollers: rawmaterial--conditioning--roughing--hardening—finishing--Bearings with sealed bearing to prevent dander oxide into the bearing

8. PLC fixed length control device

◆It is composed of the code transition device , code control device and rotary coder.

◆The electrical control is controlled by PLC automatically to make the fixed length cutting and count possible.

9．Finish plate sent machine

◆By frame, slider, pinch, pinch roll and other supporting parts

◆Hydraulic oil cylinder lifting pinch roll, 4 kw power cycloid gear motor

10．Hydraulic shearing machine

◆Adopt the gap adjustment design which can cut the different thickness and can shear 16mm steel plate.

◆Cooperate with the signal direct from the feeder and shear automatically

11．Pendulum clamp mechanism

◆By the workbench, oscillating table, tilting mechanism, frame, the slider bearing, ascension of screwdown motor and so on.

◆To flatten, fixed-length cutting sheet metal clip to the unloading table, protection of incision and the incision of the flatness.

◆Pneumatic controls the feed device automatically.

12. Unload working table

◆it is designed with the crossing pneumatic piling device. Pneumatic device pat sheet metal

◆the unloaded can make the 12m length sheet possible

13. Hydraulic system

◆Ensure the using of every hydraulic parts

◆The working pressure of the hydraulic system is 6.3-16Mpa

◆Tydraulic tank capacity is 200 liters

◆The power of the motor is 15Kw

◆Form a complete set of soft and hard pipe, hydraulic valve, connector, etc

14. Electrical system

◆Adopted the PLC system to control and monitoring the equipment at the same time. It is controlled by LCD screen with fixed-length cutting by codes and count automatically. Supporting dc cabinets, console, etc (Cables purchased by the buyer itself)
