Zinc steel guardrail punching machine The debugging and correction methods of are as follows:

1. In the measured scale, when the center of gravity of the pendulum is at a low point, the top of the piercing head should be within 5mm of the horizontal taxi passing the pendulum's rotating axis.

2. 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 point to the zero point, otherwise, it is necessary to use the zero point adjusting screw to adjust.

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

7. Zinc steel Guardrail punching machine Put the pointer at the zero point, place the pendulum 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. Zinc steel guardrail without any heavy wheels Punching machine Let the pendulum swing freely until it stops, and the number of swings 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.
