Oct 11, 2022

1. Remove the blade and clean it piece by piece.

2. The blade can be used on all sides. Select the good side and install it tightly. Check the flatness of the blade in both horizontal and vertical directions.

3. Remove the upper blade and clean it one by one. Similarly, the blade can be used on all sides, and the good side can be fitted tightly. Check the flatness of the blade in both horizontal and vertical directions.

4. The upper blade is fixed and can not be adjusted. We adjust the clearance of the plate cutter blade by adjusting the lower blade.

5. Find the left and right of the lower blade and the two widening gap screws generally on the outside. 6. Locate the two setting screws on the left and right sides of the lower blade to push the lower blade to reduce the gap. There is a locking spare nut on the lower blade. It's usually on the inside.

7. Loosen the left and right bolts on the blade table.

8. Manually turn the upper blade down to the appropriate position, and the operator goes to the blanking area of the plate shearing machine to adjust.

9. Use the feeler ruler to coarsely adjust to 0.5 mm from the unoccluded parts of the upper and lower blades of the left hand.

10. Manually turn the blade up to the middle position and adjust it to 0.5 mm.

11. Manually turn the wheel to move the blade upward to the position on the right where the upper and lower blades are not removed. Roughly adjust the middle position to 0.5mm.

12. Manually turn down the upper blade to the appropriate position and start fine adjustment.

13. Use the feeler ruler to fine-tune the feeler ruler from the unocclited part of the upper and lower blades of the left hand to the point where three wires can enter and five wires cannot enter.

14. Manually turn the wheel so that the blade moves up to the middle position and starts to fine-tune the feeler to the point where three wires can enter and five wires cannot enter.

15. Manually turn the wheel to make the blade move up to the position on the right where the upper and lower knives are not removed, and then fine-adjust to the position where three wires can enter and five wires cannot enter.

16. The above is for the new car fine adjustment to the feeler ruler three wire can enter five wire can not enter.

17. For old cars, fine adjustment to the feeler gauge 10 can enter 20 can not enter. Or according to the required shear sheet metal thickness of 1/10- 1/20 for appropriate adjustment.

18. When the cutting edge of the plate cutter is sharp, such as the edge of the cutting plate has burrs, the gap between the upper and lower blades can be properly reduced.
