Correct protection operation of multi-station cold heading machine

Multi-stationCold heading machineIt has good surface quality and high dimensional accuracy. Because the cold hardening during the upsetting process should not be too large to reduce cracks, the product has high molding power, fixed power, electricity, and a large amount of capital is made at one time. The manufacturer of multi-station cold heading machine will summarize the correct protection operation of multi-station cold heading machine.

Correct protection operation of multi-station cold heading machine:

1. The multi-station cold heading machine has been used for a long time, and grease, carbon deposits, deposits and rust will occur inside. When the pedal is stepped on, the brake pedal will be very low. When the pedal is stepped on, the pedal may gradually rise, but the reaction force is small and the braking effect is not stable. When the brake pedal is stepped on, the air pressure is normal, but the brake pedal has not moved, indicating that the piston of the brake control valve is blocked.

2. The multi-station cold heading machine removes the brake valve and repairs or replaces it. The piston of the hydraulic cylinder of the afterburner may be blocked or the sealing ring may be damaged, and then the amount and pressure of the oil and pressure in the output brake fluid is reduced. If the brake oil pipe is damaged or the oil pipe joint leaks, the amount and pressure of the brake fluid entering the brake cylinder will be reduced. Check the brake air pressure to eliminate the defect of low brake air pressure and ensure that the brake air pressure value is between 0.45 and 0.70Mpa.

3. When the loader presses the brake and releases the brake pedal, all or individual wheels will brake, and the brake disc will become hot and weak, which is usually called "braking does not return". Regularly check the connection and sealing of the brake parts of the multi-station cold header.

4. When the brake pedal is pressed by a multi-station cold heading machine, the pedal position will become very low. When the pedal is continuously pressed, the pedal will gradually rise, but the brake pedal is very weak and feels that the brake effect is not stable. It is the air in the brake system and needs to be eliminated. The high-pressure gas generated by the cold forging machine driven by the engine enters the gas storage tank through the oil-water separator and the air pressure regulator. When the brake pedal is pressed, the high-pressure gas enters the air brake valve from there. Participate in the gas storage tank and then participates in the air after-pressure pump group. After multiple pressures occur, the cylinder pushes into the afterburner combustion chamber. The brake fluid at the other end enters the brake caliper on each wheel through the oil pipe, and pushes the piston to clamp the brake disc, and then brakes the wheels.

5. When the brake pedal is pressed by the multi-station cold heading machine, the piston of the air brake valve will prevent the passage of high-pressure gas, and at the same time make the gas in the valve touch the atmosphere. The booster pump unit returns to its position under the action of spring force, then lowers the pressure of the brake fluid in the brake pipeline, and then releases the brake on the wheel.
