The multi station cold heading machine has good surface quality and high dimensional accuracy. Because of the cold work hardening during the upsetting process, the deformation should not be too large to reduce cracks. The product has high forming power, fixed power, and electricity, and a large amount of capital contribution is made at a time. The correct protection operation of the multi station cold heading machine will be summarized by the manufacturer of Tianwei 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, which will produce grease, carbon deposition, sediment and rust inside. When stepping on the pedal, the direction of the brake pedal will be very low. When stepping on the pedal, the pedal may gradually rise, but the reaction force is small, and the braking effect is poor. When the brake pedal is pressed, the air pressure is normal, but the brake pedal does not move, indicating that the piston of the brake control valve is blocked.

2. The multi station cold heading machine shall remove the brake valve and repair or replace it. The piston of the hydraulic cylinder of the booster cylinder may be blocked or the seal ring may be damaged, and then the oil volume and pressure in the output brake fluid are reduced. If the brake oil pipe is damaged or the oil pipe joint leaks, the amount and pressure of 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 is between 0.45 and 0.70Mpa.

3. Multi station cold heading machine When the loader steps on the brake and releases the brake pedal, all or a single wheel will brake, and the brake disc will become hot and weak, usually referred to as "brake does not return". Regularly check the connection and sealing of each part of the brake of the multi station cold heading machine.

4. When stepping on the brake pedal of multi station cold heading machine, the pedal orientation will become very low, while when stepping on the pedal continuously, the pedal will gradually rise, but the brake pedal is very weak, and the braking effect is not safe. It is the air in the braking system and needs to be eliminated. The high-pressure gas generated by the engine driven cold forging machine enters the air reservoir through the oil-water separator and air pressure regulator. When the brake pedal is depressed, the high-pressure gas enters the air brake valve from there. Participate in the air tank, and then participate in the air booster pump group. After multi pressure occurs, the cylinder pushes the afterburner. The brake fluid at the other end enters the brake caliper disc on each wheel through the oil pipe, pushes the piston to clamp the brake disc, and then brakes the wheels.

5. When the multi station cold heading machine steps down the brake pedal, the piston of the air brake valve will prevent the passage of high-pressure gas and make the gas in the valve touch the atmosphere. The afterburner pump unit returns to its position under the action of the spring force, reduces the pressure of the brake fluid in the brake pipeline, and then releases the brakes on the wheels.
