What are the precautions for using a cold heading machine?

Cold heading machine is a specialized equipment mainly used for mass production of nuts, bolts, and other fasteners. Precautions for using cold heading machines:

1. When lifting mechanically, a diameter must be used Φ When lifting two steel cables with a diameter of 25 or more, first open the operating door cover of the machinery and the upper cover behind the main sliding platform. Hang the steel cable onto the four corner suspension rods of the machinery on this platform, and the angle of the suspension cable should not exceed 60 °. When lifting, it is necessary to be careful not to collide with the mechanical parts and casing.

2. It is necessary to pay attention to the level of the front, back, left, and right directions of the device to ensure the stability of mechanical operation.

3. The cold heading machine is equipped with an air pressure clutch brake, and an air pressure storage container should be installed in front of the mechanical air pressure three-point combination, which can be shared by two or used alone. Please refer to the air consumption meter of the SR clutch inch school bus for its application standards.

4. The diameter of the cable for the mechanical power distribution device should not be smaller than the main switch cable on the mechanical control box. It is necessary to ground the motor and electrical control box separately to avoid damage to the machine and personnel in case of leakage.

5. Before starting mechanical work, fill in lubricating oil or pressure oil. The capacity and viscosity index of the oil can be found in the explanation of the lubricating system.

6. Before starting the machine, check whether the wire connectors are loose and whether the screws of the machine parts are loose. After the machine has been operating for a period of time, it is necessary to check from the beginning whether the screws of each part are loose and whether the oil circuit is unobstructed normally.

7. Start the machine, start the smooth pump first. If necessary, the smooth indicator blue light will light up to indicate that the smooth pump operation is normal. Then start the main motor. At this time, the air pressure needs to reach 5.5-6.0 kg/c ㎡. The operation should be operated in inches, and each stage should be moved to check whether the machine operation is smooth. After everything is normal, check whether it is normal according to a single stroke. When parking with a single stroke and general operations, it is necessary for the main slide of the machine to be parked in the rear for convenient adjustment. Otherwise, it is necessary to adjust the cam viewpoint position of the parking position control electrical device, which will need to be adjusted due to different speeds. When performing inch operation, the interval time between each inch should be at least 2 seconds to prevent abnormal wear on the clutch. When the machine is equipped with a variable speed device, the machine should try to operate the inch school bus at a slow speed to reduce the slipping and wear caused by the clutch during high-speed operation transmission.
