Stop the machine and disconnect the power to ensure the equipment is in a stationary and safe state, avoiding sudden starts during adjustment. Clean the blades and adjustment area of debris and oil to prevent affecting adjustment accuracy.
- Prepare dedicated adjustment tools and consult the equipment manual to determine the appropriate angle range for different materials.
- Based on the material and thickness of the material to be processed, determine the target adjustment angle direction.
- Check the blades and related connections for looseness; tighten any loose parts to prevent misalignment after adjustment.
Confirm the adjustment basis based on material characteristics. For softer or thinner materials, increase the shearing angle appropriately to reduce material deformation; for harder or thicker materials, decrease the angle to ensure smooth shearing.
- Refer to the angle adjustment range indicated on the equipment nameplate to avoid exceeding the equipment's design limits and damaging components.
- Read the current shearing angle value through the equipment's observation window or a dedicated measuring tool to determine the adjustment range and direction, ensuring targeted adjustments.
Locate the equipment's angle adjustment mechanism, usually located on the side of the machine or where the blades are fixed. Slowly rotate the adjustment knob or screw using a dedicated tool.
- Maintain smooth movement during adjustment to avoid sudden angle changes due to excessive force.
- Observe the angle indicator repeatedly, gradually approaching the target angle.
- Ensure the blade angles on both sides remain consistent during adjustment to prevent unilateral shifts that could tilt the shearing surface.
- If you encounter adjustment blockage, do not force it. Check for obstructions or worn parts.
After adjustment, restore power to the equipment and conduct a no-load test run. Observe whether the blade movement trajectory is smooth and whether the angle meets expectations.
- Select a small amount of material to be processed for test shearing to check the flatness of the sheared surface and the deformation of the material to determine if the angle is appropriate.
- If the shearing effect is unsatisfactory, stop the machine again for fine-tuning until it meets the standard.
- Clean the adjustment tools and work area, record the adjustment parameters for future reference when processing similar materials.
- Check whether the adjustment mechanism is locked to prevent angle changes during operation.
