Single-column hydraulic press is mainly suitable for stretch forming of metal and non-metal

by:WORLD     2022-11-13
The single-column hydraulic press is also called the single-arm hydraulic press. The fuselage is a C-shaped single-arm structure, which is welded by submerged arc welding. After welding, it is processed by vibration to ensure that the fuselage is not deformed. The single-column hydraulic press can use the three-sided space device or other supporting equipment to expand the working range. The single-column hydraulic press is mainly used for the stretching, forming and pressing of metal or non-metallic products, and can also be used for the processing of non-metallic materials, the pressing of powder metallurgy products, the calibration of shaft parts, the pressing of sleeve parts and metal products. in the shaping, trimming and other processes.








Single-column hydraulic presses are often used in hydraulic transmission systems, and they are all relatively precise parts. People feel that the hydraulic transmission of the single-column hydraulic press is labor-saving and convenient, but at the same time, it is easy to be damaged. The main reason is that the working principle and structural characteristics of the single-column hydraulic press are not well understood, so there is no preventive maintenance method. There are three basic 'pathogenic' factors in the hydraulic system: pollution, overheating and air intake of the single-arm hydraulic press. . The three unfavorable factors of the single-column hydraulic press are closely and closely related, and any one of them will cause another one or more problems.





The function of the working medium used in the single-column hydraulic press is not only to transmit pressure, but also to ensure that the working parts of the machine are sensitive, reliable, long-lived and less leaking. The basic requirements of the hydraulic press for the working medium are: ① have suitable fluidity and low compressibility to improve the efficiency of transmission; ② can prevent rust; ③ have good lubrication performance; ④ easy to seal; ⑤ stable performance, long-term work rather than deteriorating. The hydraulic press initially used water as the working medium, and later switched to an emulsion made by adding a small amount of emulsified oil to the water to increase lubricity and reduce rust.








The single-column hydraulic press is mainly suitable for the stretching, forming and pressing of metal products. It can also process non-metallic materials, the pressing of powder metallurgy products, the correction of shaft parts, the pressing of sleeve parts, and the shaping and trimming of metal products. and other processes. This series of presses are equipped with independent hydraulic and electrical control systems, which are centrally controlled by buttons, which can realize two molding processes of fixed stroke and fixed pressure, and have the functions of pressure display, stroke, and pressure adjustment. And this series is equipped with four-column guide column to improve product accuracy, and the column and piston rod are quenched and plated with copper and hard chrome to ensure surface wear resistance and high roughness. The oil inlet of the oil pump is equipped with a unique filter device to ensure the service life of the oil pump and valve. The oil circuit connection adopts imported high-pressure hose, which greatly reduces the noise of the machine. In addition, advanced components such as imported PLC, grating protection and human-machine interface (touch screen) can be configured according to user requirements.
