Abstract

The invention discloses pressure applying equipment which comprises a compressing hydraulic cylinder (1), a high-position oil supply oil tank (2), a hydraulic oil pump (3), a prefill valve (4), a proportional valve (5) and a check valve (6). The oil conveying end of the hydraulic oil pump (3) unidirectionally communicates with an inlet of the proportional valve (5) through the check valve (6). An outlet of the proportional valve (5) communicates with an oil cavity of the compressing hydraulic cylinder (1) through a first stop type direction valve (7). The telescopic end of the compressing hydraulic cylinder (1) is provided with a pressing head (8) to apply pressure. The high-position oil supply oil tank (2) communicates with the oil cavity of the compressing hydraulic cylinder (1) through the prefill valve (4). According to the scheme, the problems that due to the fact that existing pressure applying equipment charges high-pressure oil liquid through a hydraulic oil pump in a high-pressure compressing state, pressure regulating precision is low, and pressure regulation is inconvenient can be solved.

Description

technical field [0001] The invention relates to the technical field of pressure equipment, in particular to a pressure applying equipment. Background technique [0002] In the field of metallurgical technology, pressure applying equipment is usually used in occasions that require greater pressure. The pressure head of the pressure applying equipment is driven by a compression hydraulic cylinder, and the expansion and contraction of the compression hydraulic cylinder can drive the pressure head to apply pressure. However, in the actual production process, the compression hydraulic cylinder needs to exert a relatively large pressure, and its cylinder diameter is relatively large. In order to realize the rapid expansion and contraction of the compression hydraulic cylinder, a high-level oil tank is generally used to quickly fill the compression hydraulic cylinder through the filling valve. Rapid liquid filling, and then realize the rapid expansion and contraction of the compres...
