Zinc steel guardrail punching machine The steps of debugging and calibration are as follows:

1. On Zinc steel Guardrail punching machine Of In the measurement scale, when the center of gravity of the pendulum is at a low point,

2. The top of the dismantling head shall be within 5mm of the horizontal taxi passing through the rotating shaft, Otherwise, it is necessary to lift and balance the weight.

3. Remove the weight and sample splint on the pendulum, and adjust the pointer to the maximum value,

4. Place the pendulum at the starting test position, press the release button to swing the pendulum,

5. At this time, the pointer should be at zero, Otherwise, it is necessary to use the zero adjustment screw.

6. When replacing weights of different components, it is necessary to readjust the zero point.

7. Zinc steel guardrail Punching machine Place the pointer at zero point, place it at the starting test position, press the release button, and make the pendulum swing,

8. At this time, the pointer shall not exceed 3mm outside the zero point, otherwise, oil shall be injected on the pointer bearing or the pressure of the pointer tension spring shall be relaxed for conditioning.

9. When no heavy wheel is added, the punching machine makes the pendulum swing freely until it stops, and the swing times shall not be less than 300 times.

10. After the pointer of the punching machine for zinc steel guardrail is zeroed, align an aluminum plate with an equilateral triangle hole with a side length of 61mm in the center with the hole of the sample pressing plate,

11. Press it in the center of the pressing plate, then release and fix the dismantling head of the anti-collision ring, and observe that the resistance of the anti-collision ring should not be greater than 78mJ (0.8kg · cm),

12. If the requirements are not met, adjust the three jacking screws of the removal head, and increase or decrease the tension spring pressure to adjust.

13. A small shaft is added at the rear end of the counterweight hole of the pendulum, and a straight downward screw is installed at the end of the small shaft,

14. Place it in the position to be released, and the lower part of the screw is pushed on one end of the scale or on the scale,

15. Release the pendulum, and add weights on the other end of the balance until the upper plane of the pendulum is parallel, that is, the balance stops.
