Classification of presses

1 Friction press

The friction press has the advantages of simple structure, reliable performance, low price and convenient maintenance. So far, it has a history of nearly 200 years and is still widely used. Although the control precision of the friction press is not high and the energy consumption is high, it has the characteristics of low price and simple structure, and it is still widely used in China and has a large market. Friction press is a common type of forging equipment in line with China's current national conditions. It has not been widely used in China due to the increase in the complexity of the structure and operation of the press, which in turn increases the manufacturing and maintenance costs of the press.

2 screw presses

The screw press is a press that relies on the rotation of the screw to drive the slider to move up and down, realize the return stroke upward, and perform forging downward. The screw press not only has the function of a forging hammer, but also has the characteristics of a mechanical press. Therefore, the screw press is widely used in various forging processes, especially for the precision forging process of material saving and energy saving. The screw press has a simple structure, Great versatility, the slider has no dead point, easy adjustment and maintenance, and easy mold design. It is suitable for various procedures such as calibrating, finishing, refining, and proofreading. Due to the great development of aviation industry, electric power and other industries in the 1950s, the rapid development of screw presses has been promoted.

3 Clutch type of screw press

The clutch screw press is a new type of screw press introduced in the late 1970s. This clutch-type screw press surpasses the traditional press's flywheel rotation movement mode and the structure of the screw flywheel combined body. The clutch screw press is a new type of screw press that breaks through the traditional transmission mode and has the advantages of forging hammer, mechanical press and hydraulic press.

The clutch type screw press is a new type of screw press. When working, the unbalanced inertia and inertia moment of the moving part of the screw press will arouse the vibration of the base of the fuselage, and the vibration caused by the strike is the strongest. Clutch screw press is a new type of high-efficiency, energy-saving, new general-purpose electromechanical-hydraulic integrated forging equipment. It has the advantages of large output energy, high number of blows, computer control, long die life, programmable pre-selection and setting of working parameters, fault display, etc. It is widely used in precision forging, die forging, extrusion, finishing and other processes.
