1. Overview
Production line: NC uncoiling, leveling and cut-to-length
Model:T44K—0.5-3mm×1600mm
The machine is used for uncoiling, leveling, auto-cut-to-length and material Stacking of cold-rolled sheet, galvanized sheet coil material. The automatic degree and efficiency are high and the worker labor intensity is low. Electric controls the linkage, and it uses Ac frequency conversion and servo control. The processing accuracy is high. The whole production line realizes the automatic control integrate of mechanical, electrical, hydraulic.

3. Brief description
a. Coil loading car
Hydraulic lift, load-bearing capacity ≤25t, mechanical travel
b. Uncoiler (hydraulic opposite vertex collapsible tension type)
Dynamic decoiling and coiling, motor cycloidal pinwheel reducer chain transmission. Adopts the brakes to link the power and decoil (coil).
c. Strip head, material-leading and leveling machine
lIt has hydraulic telescopic feeding guide, and has expansion and lifting action.
Roller rubber roller rotation is driven by motor which is on the hydrauliccantilever swing support through reducer chain transmission, and then uncoils the coils.
lHydraulic oil cylinder drives the pressure head to press the sheet and sheet
heads up and down, in convenience of entering into the leveling device.
lTwo roll leader and 15 rollers leveling is driven by motor, reducer,enclosed
gear distribution box and cardan. Leveling upper roller adjusts electrically by two groups of worm transmission. There is 3 groups of auxiliary pressure rollers on the leveling roll and 3 groups of auxiliary support rollers under the leveling roll.
lLeading roll diameter is120mm, and adopts 40Cr, and the leveling roll
adopts 42CrMO and mid-frequency quenching.
lMain motor 37kw adopts frequency conversion regulation, the linear
speed is 10-50m/min, and coordinate
d. Hydraulic buffer stock gap bridge (loop):
The sheet metal enters into trimming equipment with swing, and after attachment production, it swings down.
e. Correcting set:
In case of the right and left line deflection of the sheet, it consists of support, adjusting screw and correction wheel, and its adjustment range is 600-1600mm.
f. Automatic cut to length feeding and 5 rollers leveling machine:
One pair of pinch roller (lower roller is mid-frequency quenching, upper roller rubber is covered roller) finishes the rapid automatic fine cut to length under the driven of AC servo motor, reduction gear and coupling. There are second leveling machine with 5 rollers in front of the pitch roller.
g. Shearing machine
Mechanical QA11-3×1600 high speed pneumatic clutch shearing machine, idle stroke cutting times is 105min-1.
h. Conveyer belt
The sheet sheared down is moved out of shearing machine and then does the backward transport for material connection and frequency conversion control.
i. Hydraulic lifting collecting table
(With blowing blanking and material settle device)
j. Hydraulic system
4KW motor,10L plunger pump,Max. pressure 25MP,actual pressure≤15MP.Main hydraulic cylinder adopts import seal, and other attachments adopt domestic high quality products to confirm it wears well and each joints will not have the problems of leakage of oil and gas.
k. Electrical control system
The whole line adopts centralized control, and it is controlled by touch screen, PLC and AC frequency conversion and servo. The cutting length and number of the sheet can be controlled by CNC system, and it has the operation methods of manual and automatic. With automatic method, the whole leveling and cutting process is controlled by computer and the control software has the function of error compensate.
l. Pneumatic control system
It consists of air treatment unit, pipeline, air valve and cylinder and so on.
Note: Air source is supplied by the user: a set of 0.9 m3 pressure 0.8 MPa air compressor.
