Detailed Equipment Specifications
Hydraulic Uncoiler + Loading Cart
- Pneumatic pressure arms prevent coil unraveling during rotation.
- Side flanges on both sides prevent coil spreading.
- Wedge-type expansion: more durable than standard hinge expansion.
- Turntable made of 48 mm thick steel plate—resists deformation.
- Main shaft: 40Cr alloy steel—enhanced durability.
- Rotary hydraulic cylinder expansion ensures no rotation slippage.
- Reinforced pneumatic brake disc—resists fracture during emergency stops.
- Clutch: 40Cr, quenched & tempered for higher strength.
- Reversible operation for both coiling and uncoiling.
Shear & Butt Welding Platform
- Components: front/rear pinch rolls, guide units, movable pressure plates, hydraulic shear, welding unit.
- High automation for easy head/tail cutting and welding.
- Raw material: Q195–Q420 hot-rolled low-carbon steel, galvanized or Zn-Al-Mg strip.
- Width ≤ 500 mm; Thickness: 2.0–5.0 mm.
- Key components:
- Pinch rolls (2 sets): φ100×500 mm, chrome-plated.

- Inverter: 45 kW vector type.
- Exit cage: barrel-shaped with 8×φ120 mm exit rolls (45# seamless tube, quenched).
- Exit speed: ≤40 m/min (follows line speed).
- Feeding mode: outer-in, inner-out fixed-loop.
6-Station Punching Unit + Servo Feeding System (Punching dies not included)
- Infeed pinch rolls: 2-roll, 1.5 kW motor, pneumatic lift.
- 7 leveling rolls (4 bottom, 3 top) before punching for flatness and precision.
- Die frame: mortise-and-tenon structure, secured by countersunk screws. Made of 45# steel, precision-machined on CNC center.
- Hydraulic cylinder rods connected via pinned joints to prevent loosening.
