Today, the editor will list the steps for the normal start of the Four-column deep drawing hydraulic press machine for you. Hope to be helpful to buyers and users:

1. Check whether the four-column hydraulic oil pump, control valve, and pressure gauge are normal, and whether the oil temperature is within the allowable range;

2. Check whether the mold has cracks and whether the fastening screws are loose;

3. Turn on the power switch of the Four-column deep drawing hydraulic press machine and start the cooling cycle motor;

4. The Four-column deep drawing hydraulic press machine starts the main oil pump motor;

5. Check the oil level of each oil tank, whether there is oil leakage in each oil circuit and hydraulic pipe fittings, and whether each connecting piece is loose;

6. Check the deflection of the pressure pointer of the pressure gauge. If it is found to swing or not move, stop and check the rated pressure of the equipment, and the limit value shall not be exceeded during use:

7. Check and clean the work surface or mold of the Four-column deep drawing hydraulic press machine. Other sundries:

8. Adjust the working mode switch to the 0 position, perform manual operation, check whether the upper and lower limit switches of the movable beam are safe and reliable, whether there is abnormal noise in the hydraulic system of the Four-column deep drawing hydraulic press machine, and flexible and reliable photoelectric eyes, operation buttons, emergency stop switches, and safety protection devices ;

9. After everything is normal, select the work switch according to the required work mode.

What are the problems that are easily overlooked in the use of the 150-ton small Four-column deep drawing hydraulic press machine?

1. The first is the problem of the hydraulic oil of the 150-ton small Four-column deep drawing hydraulic press machine

When there is a problem with the hydraulic oil in the 150-ton small Four-column deep drawing hydraulic press machine equipment, it will greatly affect the working efficiency of the hydraulic press, usually more frequently. For the viscosity and deterioration of hydraulic oil, the oil absorption and utilization efficiency of the hydraulic press is affected, and the hydraulic oil cannot be converted into sufficient kinetic energy. 

2. Environmental cleaning problems of 150-ton small Four-column deep drawing hydraulic press machine

This problem cannot be ignored, because many times the 150-ton small hydraulic press four-column three-beam hydraulic press has abnormal conditions, mainly because the working environment of the 150-ton small Four-column deep drawing hydraulic press machine has not been properly cleaned and maintained. Accumulated dust can contaminate oil or contaminate work surfaces. On the one hand, it will affect the oil quality of the hydraulic press, and on the other hand, it will also affect the accuracy of the hydraulic press equipment.

3.150 ton small Four-column deep drawing hydraulic press machine heat dissipation problem

The heat dissipation problem cannot be ignored. This is not a small problem. The thermal energy accumulation of the 150-ton small Four-column deep drawing hydraulic press machine will cause equipment damage, and overheating will significantly reduce the working efficiency of the 150-ton small Four-column deep drawing hydraulic press machine.

Operation and debugging of Four-column deep drawing hydraulic press machine and matters needing attention

Four-column deep drawing hydraulic press machinees are often used in pressing processes and press forming processes, such as: forging, stamping, cold extrusion, straightening, bending, flanging, sheet drawing, powder metallurgy, press fitting, etc. It has a wide range of uses. In the process of using the hydraulic press, you need to understand the basic operation, debugging and some precautions.

1. Determine the power loss and temperature rise of the four-column hydraulic system. If the losses are large and the temperature rises, it will affect the normal operation of the system. The cause should be analyzed and measures taken to resolve the problem.

2. Four-column deep drawing hydraulic press machine can detect force, speed and stroke adjustability, and operation reliability. If problems are found, they should be corrected.

3. For the hydraulic system of the four-column hydraulic system, the working parameters of each working cycle and various actions that make up the cycle, such as force, speed, acceleration, starting and ending points of the stroke, time for each action, and the total time of the entire cycle, etc. . Adjusting to the correct value allows the system to obtain a correct and reliable duty cycle.

4. Text records of the operation and debugging of the Four-column deep drawing hydraulic press machine. After approval, the equipment technical documents are entered as the original technical basis for equipment maintenance, which plays a very important role in the fault diagnosis of the Four-column deep drawing hydraulic press machine.

5. Personnel who do not understand the structural performance or operating procedures of the Four-column deep drawing hydraulic press machine shall not start the machine without authorization; during the operation of the Four-column deep drawing hydraulic press machine, the machine should not be checked and adjusted; when the Four-column deep drawing hydraulic press machine finds serious oil leakage or other abnormal conditions (such as unreliable operation, noise , vibration, etc.), stop the cause analysis, try to eliminate the cause, and do not put the disease into production:

Sixth, do not overload or exceed the eccentric distance of the Four-column deep drawing hydraulic press machine: do not exceed the stroke of the slider. The clamping height shall not be less than 600mm. The grounding of the electrical equipment of the Four-column deep drawing hydraulic press machine is firm and reliable: End the work: put the slide of the Four-column deep drawing hydraulic press machine in a low position.

7. Operation, debugging and precautions of the hydraulic press should also be noted that the exposed sliding surface of the Four-column deep drawing hydraulic press machine should be kept clean, and oil should be injected before work. Its maintenance, the control circuit diagram of the Four-column deep drawing hydraulic press machine, and the schematic diagram of the hydraulic system of the Four-column deep drawing hydraulic press machine, etc.
