What are the safety operation specifications of four-column hydraulic press

1, the implementation of mandatory national standard JB3915-85 "four-column hydraulic press safety skill conditions", the user must not change. If changed, all results by the user.

2, the machine to improve, equipment, debugging personnel it is necessary to have the corresponding qualifications of lifting personnel, understand the four-column hydraulic press skills professional mechanical (electrical) skills, and carefully read the product standards, to improve, equipment debugging.

3, the machine must be firmly grounded before use to ensure personal safety.

4, the slider upward and downward projection areas are risk areas, the upper and lower data is necessary to stop, use things to complete the slider, any part of the main body shall not enter the risk area.

5, in the four-column hydraulic press repair, mold, it is necessary to use safety bolts to determine the equipment or slide the following solid wood to ensure that the slider is firmly supported or determined, and admit that the press is in a non-working state, and block the power supply.

6, hydraulic strictly stop the operating pressure beyond the standard, to stop out-of-range suppression, mold closing height should be greater than the smallest four-column hydraulic press opening.

7, the four-column hydraulic press in use does not allow over-biased load suppression, part of the load should be less than 3% of the useful scale (such as the center of the table in the left and right direction of the difference should be less than 30mm. The front and rear directions are the same control.)

8, press the trip switch, should often check to ensure sensitive and reliable. Limit switch lower limit switch screw device is slipping? Move on the switch frame. When the user adjusts the switch orientation, stop overstepping the screw. When the equipment is running, do not touch the switch sensing equipment with hands or other objects to avoid problems, resulting in personal accidents or problems with the four-column hydraulic press equipment.

9, always check the hydraulic pipe and connecting nut force, found loose nuts, pipes and components leakage, it is necessary to close in time to stop tightening pipe fittings, screws or other components under pressure.

10, as long as the one-arm four-column hydraulic press with buffer is punched, it is necessary to open the punching equipment on the buffer equipment, and ensure the height of the buffer (tolerance must be less than 0.015% of the buffer center distance, the maximum is not greater than 0.35mm). The user needs to pad in the cushion, which should ensure that the cushion is high, and has the strength and external hardness to meet the requirements to accept the corresponding buffer force.

11, when the stamping equipment, stamping process, impact pressure should be 1.3 times of the product selection equipment.
