6.Introduction to the performance of the main components

6.1.Material dispensing rack

6.1.1.Function Description：The unwinding stand fixes the material roll onto the expanding and contracting section of the main shaft, and the support platform supports the inner diameter of the material roll. During automatic operation, the main shaft rotates intermittently to start unwinding through the control of the material ring. It includes the main shaft expansion and contraction section, the pressure arm section, and the material ring control section.

6.1.2.Material Roll Width: 70mm-400mm

6.1.3.Material Rack Load Capacity: 3T

6.1.4.Expansion Method: Hydraulic expansion

6.1.5.Spindle Expansion Range: Φ480mm-Φ520mm

6.1.6.Spindle Drive Motor: AC geared motor, frequency converter controlled

6.1.7.Main Drive Method: Belt drive

6.1.8.Spindle Feeding Direction: Counterclockwise (feeding from left to right)

6.1.9.Material Rack Pressing Arm:  Presses the material and prevents the material roll from loosening after the strapping is removed, providing personal safety protection.

6.1.10.Pressing Wheel Specifications: 1 PU rubber wheel

6.1.11.Pressing Wheel Drive Method: Non-powered, moves with the material roll.

6.1.12.Pressing Arm Action Method: Pneumatic drive, can be manually raised and lowered.

6.1.13.Limit Device: A-frame limit switch.

6.1.14.Material Loop Control: Roller-type inductive material loop control. When the material loop sags, the sensor provides feedback signals to control the start and stop of the unwinding rack, ensuring a sufficient and reasonable buffer loop between the unwinding rack and the leveling feeder.

6.2.Leveling and feeding machine

6.2.1.Function Description: The straightening machine flattens the material surface and feeds the material to the stamping equipment according to the set length and speed.

6.2.2.Driving Method: AC servo motor, AC 2.9KW

6.2.3.Straightening and Feeding Roller Combination: Straightening rollers, feeding rollers.

6.2.4.Straightening Roller Combination: 9 straightening rollers (5 upper, 4 lower, surface thickened hard chrome plating and grinding treatment, HRC60±2).

6.2.5.Feeding Rollers: 2 rollers (surface thickened hard chrome plating treatment, HRC60±2)

6.2.6.Straightening Amount Adjustment Method: Manual adjustment

6.2.7.Straightening Amount Display Method: Dial on the eccentric shaft

6.2.8.Straightening Amount Setting Accuracy: 0.1mm

6.2.9.Straightening Roller Support: Deep groove ball bearing

6.2.10.Straightening Roller Release Method: Pneumatic

6.2.11.Straightening Roller Material: High-carbon chromium bearing steel

6.2.12.Straightening Accuracy: ≤0.3mm/(200mm*200mm)

6.2.13.Feeding Line Height Adjustment Method: Electric adjustment

6.2.14.Roller Driving Method: Gear drive, all gears are manufactured to carburized and ground 6th grade precision standards.

6.2.15.Feeding Repeatability Accuracy: ±0.2mm when feeding 500mm (guiding tolerance, the mold needs positioning pins)

6.2.16.Maximum Output Speed: 15m/min

6.3.Discharge support device

6.3.1.Function description: Equipped with guide wheels and support rollers to ensure reliable transfer of the material strip from the point of fixed length cutting to the mold.

7.Correction Capability Reference Table (Yield strength: 245 N/mm²)

Note: 1. Specifications marked with an asterisk (*) indicate that the material of this specification is acceptable, but the leveling effect may not meet the standards;

2. Tensile strength is a reference value calculated based on the yield stress; the straightening capability should be confirmed using the yield stress value;

3. Due to variations in material composition, roller marks may sometimes be present on the material;

4. Leveling capability and effect: It is necessary to ensure that the raw material has a uniform metallographic structure, that the raw material does not have transverse sickle-shaped bends, and that the material is undamaged.
