What is a four-column hydraulic press? What is the working principle?
7.18 2022
The hydraulic press is a machine made according to Pascal's principle to realize the processing technology. It is a kind of machine that uses liquid as the working medium, and uses the static pressure of the liquid to process metal, rubber, powder and other products through the change of pressure. Hydraulic presses can be divided into hydraulic presses and hydraulic presses according to the different liquid media inside. Hydraulic presses mainly use the control of water-oil balance and the transmission of static pressure to work. The hydraulic press is a kind of oil cylinder/piston that drives the hydraulic pipeline by using special hydraulic oil as the medium and the power of the hydraulic pump. Also known as the four-column hydraulic press, the four-column hydraulic press is mainly used for the processing of plastic materials.
There are two main classification forms of hydraulic presses: according to the structure form and according to the main purpose. According to the structure, it can be divided into four-column type, single-column type, vertical type, horizontal type, etc. According to the main purpose, it can be divided into powder molding, stretching molding, extrusion molding, bending molding, etc.
