Embodiment Construction

[0030] The present invention will be further explained below in conjunction with accompanying drawing:

[0031] as attached figure 1 As shown, the main hydraulic cylinder 16 is a plunger hydraulic cylinder, and the forging hammer head 17 of the quick forging hydraulic unit is connected to the plunger of the main hydraulic cylinder 16 through a movable beam 18, and when one end of the plunger is filled with pressure oil, the forging hammer head 17 Empty drop; the single-outlet rod lifting hydraulic cylinders 15, 15' are placed on both sides of the main hydraulic cylinder 16, and the single-outlet rod in it is linked with the forging hammer head 17, and when the rod cavity is filled with pressure oil, the forging The hammer head 17 realizes the return stroke upwards; and when the forging hammer head 17 descends in the empty space, the rod chambers of the two single-rod hydraulic cylinders 15 and 15' are connected to the oil tank, and an electro-hydraulic proportional valve is se...

Abstract

The invention relates to a hydraumatic fast forging machine set capable of being supplied with pressure superimposedly by hydraulic pumps and a high pressure accumulator. According to the hydraumatic fast forging machine set capable of being supplied with the pressure superimposedly by the hydraulic pumps and the high pressure accumulator, aimed at the technical disadvantages of increased equipment investment, expanded electric capacity and more no-load energy consumption caused by reasonable number and configuration manner of the hydraulic pumps in the conventional hydraumatic fast forging machine set, the high pressure accumulator, electromagnetic reversing valves, electro-hydraulic proportional valves and an energy reserving and storing device which electronic control system consists of sensors and a PLC are added for storing energy emitted ineffectively in a working circle, and the set number of main hydraulic pumps can be reduced by supplying pressure oil to main hydraulic cylinders during the rolling working process of hydraumatic machines by a control system. By means of the machine set, the objectives of saving cost, reducing investment and optimizing resource allocation can be realized.

Description

technical field [0001] The invention relates to a hydraulic rapid forging unit, in particular to a hydraulic rapid forging unit in which a hydraulic pump and a high-pressure accumulator are superimposed to compensate for pressure supply, and belong to the technical field of hydraulic transmission control. Background technique [0002] The hydraulic fast forging unit is a new type of forging equipment. Because of its high degree of automation, good control precision, and saving raw materials, it is the first choice for high-end forging industries at home and abroad. It is widely used in machinery manufacturing and forging of high-quality and high-performance materials. . At present, the components of the relatively good domestic fast forging units are designed and manufactured according to the international advanced level, and the key components are imported foreign brand products, so the equipment cost is very expensive. Due to the large energy consumption of the forging ma...
