Step 1: Foundation Installation Preparation and Positioning
1. Site Environment Preparation: Select a flat, hardened ground surface, ensuring the workshop temperature is between 20-26℃ and humidity is 50%-60% to avoid affecting accuracy. For large equipment, foundation grouting is required beforehand to ensure the frame remains level and does not settle or wobble.
2. Frame Leveling: After the equipment is in place, use a level to check the levelness of the frame in both longitudinal and transverse directions. Adjust the anchor bolts, controlling the level error within 0.05mm/1000mm. Tighten the anchor bolts to prevent vibration and displacement during operation.
3. Wiring and Accessory Inspection: Connect the power supply to the corresponding voltage according to the instruction manual, connect the grounding protection wire, and check that the air supply and hydraulic oil levels meet the requirements. Perform a 30-minute no-load test run to confirm that the motor and transmission system are operating normally without abnormal noise.
Step Two: Precise Calibration of Core Components
This is a crucial step in ensuring cutting accuracy. The calibration requirements for different components are as follows:
1. Cutter Shaft/Cutting Head Calibration
Slitting Machine Cutter Shaft: Use a laser calibrator to check the parallelism of the spindle and the perpendicularity of the cutter. Adjust to the standard range. The parallelism error must be ≤0.03mm to ensure all blades are on the same cutting surface, avoiding problems such as incomplete cutting of aluminum foil or burrs.
Laser Cutting Head: Calibrate the perpendicularity of the cutting head to the worktable surface and adjust the focal length to ensure the focus falls on the aluminum foil surface, avoiding incomplete cutting or overheating.
Vibrating Cutting Head: Correct the perpendicularity of the cutter bar and test the vertical vibration amplitude of the cutter head to ensure the cutter head extension length meets the cutting thickness requirements.
2. Feeding and Positioning System Calibration
Calibrate the parallelism of the feeding rollers to ensure the feeding process does not deviate. Test the feeding accuracy multiple times. After 10 consecutive feedings, the cumulative error must be controlled within ±0.1mm. If the error exceeds this range, adjust the transmission clearance.
The slitting machine requires calibration of the tension control system. Set an appropriate tension value based on the aluminum foil thickness, and conduct a no-load test to confirm tension fluctuation is ≤1% to prevent wrinkling and loosening of the aluminum foil during operation.
3. Positioning Dimension Calibration: Import standard-sized cutting samples. After actual cutting, measure the finished product dimensions with a micrometer. Compare the measured values with the set values and adjust the system parameter compensation until the error is stably controlled within your required accuracy range.
Step Three: Trial Cut Verification and Finishing: After calibration, test cut 5-10 pieces using your actual production aluminum foil:
1. Check the dimensional error and cross-sectional quality of each piece. If all indicators meet the requirements, the calibration is successful.
2. Secure all adjusting screws and mark the calibration points for future reference during routine checks.
3. Organize the installation and calibration records, recording the current parameter settings for quick recovery in case of accuracy drift.
