hydraulic drawing machine operating procedures

In order to better maintain the equipment, improve the operation rate of equipment, specially formulated the following operating procedures and precautions.

佛山市佛冶机械设备有限公司 1. Operators in the boot before the check whether the hydraulic station level gauge within the specified range, such as the lack of hydraulic oil, please promptly notify the mechanic to add hydraulic oil. In turn, turn on the hydraulic pump, and then the clamp car, mandrel car, supporting the cylinder and other auxiliary equipment to test and check the high pressure hose is leaking, oil spills.

In the operation of the car clamp clamp clamp when the need to keep the two jaws block, or need to re-clamping, so as to prevent the head when the ball is damaged slip。 4, when the clamp clamped the head, first with two small hydraulic pump to pull out a section of the capillary, and then turn on the other hydraulic pump to improve the extubation speed。 5, in the extubation is about to end must be reduced pump, slow down, as long as there is one or two pumps to work on the line, thereby reducing the steel pipe in the demoulding of the hydraulic system to produce an instantaneous anti- Punch pressure, to avoid unnecessary damage to the equipment。 6, the internal mold wear into the capillary, you can not repeatedly use the mandrel impact, which will cause the mandrel car hydraulic motor drive shaft pull off。

If you meet the individual capillary wall thickness tolerance or tension is too large, you must reduce the pump operation or change the process to prevent the process of drawing jaws in the process of slippage. , The head of the broken hydraulic system to produce a huge recoil pressure, resulting in tubing and weld fracture and oil spills. For example, in the extubation of the mandrel break need to take the outer mold, as far as possible not to use the main cylinder to pull the capillary out of the outer die. Due to the operation of the main cylinder piston rod is often the phenomenon of the top bend, which will oppress the steering sleeve and copper sleeve caused deformation. & Nbsp;
