by:WORLD     2022-09-30


Safety production is not only related to the life of the operator, but also the service life of the equipment. For the four-column hydraulic press, the correct operation and use must be trained in the early stage, which is not only responsible for yourself, but also for the company's property. Below we will introduce how to properly operate and use the four-column hydraulic press equipment.








1. The company conducts strict training for the operating staff. Only the trained staff can operate the equipment, and other personnel are not allowed to operate the equipment at will;



2. Understand the structure, important components, operation and common sense of the four-column hydraulic press;








3. Before work, you should wear work clothes and safety helmets, and wear them in strict accordance with the regulations;








3. Before starting the machine, check whether the oil cylinder leaks oil, whether the screws are loose, whether there are sundries on the mold, whether there are people around the running part of the equipment, etc., to ensure safety before starting;








4. After the four-column hydraulic press works, it should be idling for 5 minutes to check whether there is noise in the fuel tank, whether there is oil leakage in the hydraulic components and pipelines, and whether the oil is lower than the normal line;













5. Start the equipment to test the pressure, check whether the pressure reaches the working pressure, whether the operation of the equipment is normal and reliable, and whether there is leakage;








6. Adjust the working pressure, but should not exceed 90% of the rated pressure of the equipment, test a workpiece, and then produce after passing the inspection;








7. When the movable beam of the hydraulic press slides, it is strictly forbidden to reach in and touch it, and personnel should stay away from the equipment;








8. If there is a fault, it should be stopped for maintenance, and the safety lock should be opened at the same time to avoid accidents caused by the automatic falling of the oil cylinder or the misoperation of personnel;








9. If the mold needs to be replaced, it should be stopped and replaced. After the mold is installed, it should be manually calibrated and operated by jogging, and the mold should not be damaged too quickly;








10. No smoking, welding and cutting around the four-column hydraulic press, no storage of flammable and explosive items, and fire prevention measures;








12. After the hydraulic press is finished, the power supply should be cut off, the column of the equipment should be wiped clean, the lubricating oil should be added, the molds and workpieces should be cleaned and placed neatly;








13. Check every month whether the hydraulic oil is deteriorated, the impurities are excessive or reduced, and it should be replaced in time to ensure that the oil is clean and clean so that the equipment can run smoothly;








14. It is necessary to record the maintenance and maintenance records of the hydraulic press to lay a solid foundation for the work of the next cycle.








The four-column hydraulic press is a relatively advanced equipment in China. It requires relatively high skills for the operator. Only when the installation regulations are correctly operated and used, can there be fewer failures and longer service life.
