In the machinery industry, the structure of the hydraulic press is varied, and the structure of the hydraulic press for different purposes is also different, divided from the frame type, there are vertical and horizontal. From the frame composition, there are column type, single arm type and frame type, and column type is divided into four columns, two columns, three columns and multiple columns. From the number of working cylinders, there are single cylinders, three cylinders or multiple cylinders.

1, three beam and four column hydraulic press This is the most common type of structure, especially the large free forging hydraulic press is usually used as a structural type.
2, the whole frame type hydraulic press main frame for the whole welding or whole casting, as follows: pull type free forging hydraulic press.
3, single-arm hydraulic press This structure is mostly used for stamping hydraulic press or small forging hydraulic press. Single arm hydraulic press frame for the whole cast steel structure or steel plate welding structure, simple structure, work can be approached from three directions, simple and convenient operation. However, the rigidity of the whole frame is poor, in order to ensure that the frame has enough strength and stiffness, sometimes the frame is relatively bulky.
4, three-beam multi-column combined hydraulic press for large die forging hydraulic press, its large tonnage makes the body structure design complicated, limited by manufacturing, installation, transportation and other conditions, the body often adopts a separate combination structure. 300MN die forging hydraulic press adopts a three-beam multi-column combination structure.
5, multi-plate composite frame hydraulic press for large multi-direction die forging hydraulic press, its large tonnage and higher requirements for press stiffness make the body structure design more complex.
6, the prestressed hydraulic press frame made of steel belt winding method has the characteristics of light structure, small size, good fatigue resistance and low cost.
1, computer optimization structure design, simple structure, economic and practical.
2, hydraulic control using cartridge valve integrated system, reliable action, long service life, hydraulic impact is small, reduce the continuous pipeline and leakage point.
3, independent electrical control system, reliable work, intuitive action, easy maintenance.
4, the use of button centralized control, with adjustment, manual and semi-automatic three modes of operation.
5, through the selection of the operation panel, two kinds of molding process can be realized, such as fixed range and fixed pressure, and it has the functions of retaining the rolling time.
6, the working pressure of the slider, the travel range of no-load express down and slow work can be adjusted according to the process needs.
