1. In mechanical lifting, two cables with a diameter greater than 25 should be used for lifting.

The cold heading machine is a specialized equipment mainly used for mass production of fasteners such as nuts and bolts. According to the theory of metal plastic deformation, the bolt cold heading machine applies a certain pressure to the metal blank at room temperature, causing it to undergo plastic deformation in the mold cavity, forming according to the specified shape and Size. The standard part machine is equipped with a pair of bevel gears at one end of the crankshaft, and a cam device is installed on the driven bevel gear shaft, with a scissor slider vertically mounted on the roller shaft of the cam device. This utility model overcomes the shortcomings of the prior art, with a small running friction coefficient and impact force between the components of its feeding and cutting mechanism, making the equipment run smoothly, effectively reducing operating noise, and greatly improving product quality and productivity. First, open the operation door cover of the machine and the upper cover behind the main sliding platform. The steel wire rope should be suspended on the four corner lifting rods of the machine platform. The angle of the lifting ears should not exceed 60 degrees. When lifting, care must be taken to ensure that the lifting ears do not collide with mechanical components and the casing.

2. Second step. During installation, attention must be paid to the level in three directions: front and back, left, to ensure the stability of mechanical operation.

3.The cold heading machine is equipped with a pneumatic clutch brake. Before the mechanical pneumatic three-point combination, a pneumatic reserve container should be set up. Two containers can be shared or used separately. For related specifications, please refer to the air consumption table of the SR clutch inch motor school bus.

4.The mechanical power distribution and installation cables should not be less than the main switch cable on the mechanical control box. At the same time, the motor must be grounded separately from the electrical control box to prevent harm to the machine and personnel in case of leakage.

5. Before mechanical operation, lubricating oil or pressure oil should be added first. The lubrication system should explain the volume and viscosity index of the oil.

6. Before starting, check whether the wire joints are loose and whether the screws of each component are loose. After the machine has been running for a period of time, the screws of each component and the oil circuit should be checked again for looseness and smoothness. Chapter Seven. To start the machine, first start the lubrication pump, and the blue indicator light must be on, indicating that the lubrication pump is operating normally, and then start the main motor. At this time, the air pressure needs to reach 5.5-6.0kg/c. The machine should first be moved in inches to check whether the machine runs smoothly, and then check whether the stroke is normal again. To check if it is normal, when the machine is in single stroke and general operation stops, the main sliding platform must be at the rear. Otherwise, the cam angle position of the electrical control by the parking position must be adjusted, as different speeds require adjustment. In inch operation, the interval time for each inch is greater than 2 seconds, so that the clutch does not experience abnormal wear. When the machine is equipped with a shifting device, the machine attempts to work at low speed to reduce the sliding wear of the clutch during high-speed operation.

These requirements drive the use of all-electric bending pipe technology bolt cold heading machines.
