Product Description
CAZJ-1250B Slitting line machine
Technical Specification
CNC precision slitting line is mainly used for strip silicon steel sheet coils processed by high-speed precision, mainly consist of:
1. Motor Decoiler with trolley 1 set
2. Guard rail/shaft 2 sets
3.Slitter with rolling table 1 set
4.Material photoelectric detection device 2 set
5.Pneumatic tensioner 1 set
6.Servo Recoiler with trolley 1 set
7.Pneumatic system 1 set
8.Electrical control system 1 set
9.Alloy cutter 10 sets
Introduction:
1. Decoiler
a. Hydraulic operation to lift arm to support the opening end of decoiler.
It will provide stable decoiler movement and reduce load pressure.
b. Shaft OD: About Φ460-520mm
c. Braking device: Motor braking system
Axis core structure:composed of six set of wedge block, use the advanced non-welding structure.
d. Braking device: using servo motor brake. (Active feeding way)
e. Mechanical structure: Processed by steel plate and steel welding.
2. 1250 Precision Slitting machine
a. Rotary Slitting Shaft can turn forward and backward, slitter width can be adjusted according to the alloy cutter Drive by AC motor.
b. Cutting ways: Circular knife type.
c. Mechanical structure:
Shaft material: SCM440
Shaft diameter: Φ 120mm up and down each one, no key structure.
d. Knife shaft adjustment: the upper and lower shaft fixed, unilateral adjustment, control accuracy effectively.
e. Knife shaft fastening: up and down knife shaft adopts double nut as axial fastening.
f. Cutter and rubber gasket: each seven sets
g. The slitter is driven by 1.5KW AC motor, using the reduction gear, single output.
3. Strips Separating Devise and Pneumatic Tensioning Station
a. Each strip is separated by separators, and tensions will be applied before re-coiling. The tension on strips will enable proper coiling and prevent collapse after removing from re-coiler.
B. Tensioner equipped with three groups of cylinder pressure institutions
C. Tensions can be adjusted according to different type of slitting material. Structure is flat felt type.
D. Especially for silicon steel sheet design pressure burr device, manual synchronization control.
4. Recoiler
1. Operating function: Slit the steel and received, manual to put the slitted coil to trolley. Recoiler driven by servo motor to rotate, equipped with auxiliary type manual work station to control the forward and inversion. Equipped with manual wrench, manual adjusting material support plate tight and narrow.
2. Mechanical structure:
a. Strip coiler: composed of motor, reducer and the supporting plate.
b. Coiler ID: Φ460-520 mm
c. Plate expand and narrow: with a wrench, using manual to regulate expand and narrow state, has a seam type structure.
d. Axis core structure: composed of six set of wedge block, use the advanced non-welding structure.
e. Coiler OD:Φ1200 mm (max.)
f. Slit coil weight: 5T (max.)
g. Coiling way: overwind
5. Photoelectric detection system
Equipped with two sets of photoelectric detection device, which located in the buffer pit walls which front the rolling shear and tensioner.
Photoelectric detection device is length measurement and material distance measuring, to reach automatic feed and automatic receiving function.
Two sets of photoelectric detection device contains six photoelectric switches.
6. Pneumatic System:
Solenoid valve and manual valve loop control to hydrosphere and oil separation, it also adjust pneumatic pressure.
7. Operation control system
PLC control system, effectively realize automatic feeding, automatic roll cutting, automatic receive material.b. Human touch screen operation system, can be set freely roll cutting speed, material cutting length.
