Maintenance and common problems of precision press machine
The precision press machine is a pressing process suitable for plastic materials. Such as powder product molding, plastic product molding, cold (hot) extrusion metal molding, sheet stretching, and processes such as transverse pressing, bending, turning through, and correction. Great attention should be paid to the storage and transfer of working oil. Oil drums should be specially marked and covered up.
In winter, be careful not to condense the air into the oil and mix it with the oil, and do not drop the rusted rust from the barrel into the barrel. A number of preventive measures taken in winter for the engine and other mechanical systems, such as covering and anti-freezing, heating and heat preservation, and changing to low-viscosity working oil, are all applicable to the hydraulic system. In winter and worse working conditions, the precision press machine system should be checked and maintained frequently, and the working oil should be changed frequently.
Common faults and maintenance methods of precision press machine: Often in the hydraulic transmission system, there are some relatively precise parts. People feel that the hydraulic transmission of machinery is labor-saving and convenient, but at the same time, they feel that it is easy to be damaged. The main reason is that its working principle and structural characteristics are not very clear, and thus its preventive maintenance methods are not well understood. There are 3 basic "pathogenic" factors in hydraulic systems: pollution, overheating and air intake. These three unfavorable factors have a close and intimate internal connection, and any one of them will cause another one or more problems. It has been proved by practice that 75% of the "pathogenic" causes of hydraulic systems are caused by these three. 1. The working oil is deteriorated due to entering dirt. 2. Overheating. 3. Enter the air. Solution: The cleaning and assembly of some major precision parts in the precision press machine system should be carried out in a very clean room, with a clean floor and closed doors and windows, and the temperature should preferably be maintained at about 200C.
