How Much do You Know about the Working Principle of Cnc Hydraulic Press?

Mar. 11, 2020

CNC hydraulic presses play a very important role in our lives, so do you know how CNC hydraulic presses work? Here is a detailed introduction:

NC hydraulic presses include hydraulic presses and hydraulic presses, which are widely used in forging forming, correction, press-fitting, etc. It is a machine that uses liquid as a working medium to transfer energy to achieve various process requirements. General customers must choose the appropriate tonnage according to their own process requirements when choosing a purchase consultation. They should know the working principle of the CNC hydraulic press, which will help us choose the right equipment. China CNC drilling machine manufacturer will introduce the working principle of CNC hydraulic press.

The oil pump sends hydraulic oil to the integrated cartridge valve block, and distributes the hydraulic oil to the upper or lower chamber of the cylinder through each check valve and relief valve, and makes the cylinder move under the action of high-pressure oil. The CNC hydraulic machine is used Equipment that uses liquid to transfer pressure. When a liquid transfers pressure in a closed container, it follows Pascal's law. The hydraulic transmission system of the four-column numerical control hydraulic press among the numerical control hydraulic presses is composed of a power mechanism, a control mechanism, an executive mechanism, an auxiliary mechanism and a working medium. The power mechanism usually uses an oil pump as the power mechanism, and is generally an integrated oil pump. In order to meet the requirements of the movement speed of the actuator, an oil pump or multiple oil pumps are selected. The above is the basic working principle of CNC hydraulic machine. I hope that it can help friends who need to know and buy CNC hydraulic machine.

The use of CNC hydraulic machine requires regular inspection and maintenance of its system, so do you know how to check and maintain the CNC Hydraulic Machine system?

1) Before assembling the hydraulic power system of the CNC hydraulic press, the fuel tank and pipeline must be thoroughly cleaned.

Residues and surface oxides are removed by a specific method and then cured. After the hydraulic transmission system is assembled for comprehensive cleaning, it is best to use the hydraulic transmission system working medium such as hydraulic oil for cleaning.

2) Regularly check and replace the working medium.

Regularly sample the working medium of the hydraulic transmission system of the CNC hydraulic machine and check whether the pollution is still within the permitted range of the hydraulic transmission system. If it does not meet the requirements, it must be replaced immediately. When the working medium is contaminated and the hydraulic drive system is faulty, it must not be replaced. Before replacing the new working medium, the entire hydraulic drive system must be cleaned once.

3) Control the temperature of the working medium.

The high temperature of the working medium of the CNC hydraulic press is not conducive to the hydraulic device. The working medium itself will accelerate oxidation and deterioration, produce various products, and shorten its service life. Generally speaking, the working temperature of the hydraulic transmission system is best controlled below 65 degrees Celsius, and the hydraulic transmission system of the machine tool should be lower.

4) Use appropriate filters.

This is an important means to control the working medium pollution degree of the numerical control hydraulic press. According to the different working conditions of the hydraulic transmission system, filters with different filtering accuracy and structure are selected for regular inspection and cleaning.
