2. Composed device

● V saddle

● Hydraulic coil car

● Hydraulic top tight decoiler

● Coil guide and pinch roll

● Rolling table & side guide device

● Leveling machine (straightener)

● PLC length control device

● 8x2200 shearing machine

● Swing pinch table

● Discharge table

● Electronic control system

● Hydraulic control system

3. Brief introduction of the equipment

(2-8) *2000 the decoiler-straightening-cut to length-piling line, mainly used for the uncoiling straightening and cutting to length of carbon steel rolls and preparing for the next processing units.

a. V saddle

● Safety storage steel roll

b. Hydraulic coil car

● The car can move levelly and vertically, which is convenient for putting the steel rolls to the uncoiler

● It is driven vertically by hydraulic pressure

● The level movement is driven by hydraulic cylinder

● The weight it can carry is 30T (Maximum)

c. Hydraulic top tight decoiler frame

● Supporting steel rolls and uncoiling

● The moveable structure of double way hydraulic top tight

● Hydraulic pressure drives the level and landscape orientation movement

● Brake system, tapered feeding plate, 400 arrester brake

d. The pressing and decoiling device

● The hydraulic pressure controls the lifting of the decoiling rollers

● 7.5 kw cycloidal pinwheel decelerator drives steel rolls running

● Through hydraulic shovel, hydraulic balance device and hydraulic press against steel ,etc to feeding steel plates

● Hydraulic pinch and pre-levelling system which is driven by the JCT-45kw exchange speed-control motor, JZQ500 decelerator, consists of the gear distribution box and gear clutch

● The machinery structure is made by the welding and processing of steel plate and steel

e. Rolling table &side guide device

● 2-meter table is made up of roller rail, rack and bearing stand

● It uses the device of the vertical rolls of both sides to guide the steel belt goes into the straightening device correctly

● The vertical rolls of both sides are adjusted by the motor driving the shafts of both sides

f. Leveler

● 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 2.2kw 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 90kw direct-current electric machine, and decelerated by 850 reducer, and consists of teeth round distribution box and all-round shaft connection and hydraulic brake etc.

● The processing of rollers: raw material-conditioning-roughing-hardening-finishing.

g. PLC length control device

● It is composed of a code transition and a code control device and rotary encoder

● The electronic control system is controlled automatically by PLC, and make the fixed-length shearing and counting possible

h. 8x2200 shear machine

● Shearing model: cut from up to down hydraulically

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

● Shear electronically

● Adopt gap adjusting design to cut the material of varies thickness

● Four sides secessions, alloy steel materials and can shear 8mm steel plate safely after heat treatment

i. Swing table pinch machine

● Should the table, frame, roller, bearing, etc. Supporting 4kw cycloid reducer

● Pneumatic swing device should get out of the way shearing machine head, pneumatic control automatic deflector device

j. Discharge table

● Pieces of vertical and horizontal type pneumatic device

● Pieces out of the device

k. Hydraulic control system

● Ensure the using of every hydraulic parts

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

● Hydraulic tank capacity is 100 liters

● The power of the motor is 15Kw

l. Electronic control 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

m. The foundation engineering of the equipment

● The seller will provide the buyer the foundation floor images of the equipment in 45 days after signing contract

● The construction and monitoring of all the foundation engineering of the equipment are in the control of the buyer

● The foundation holes are reserved holes which work for the foot holes of equipment
