Abstract
The utility model relates to a rapid decompression and return stroke device of a multi-station die forging hydraulic pressure machine. The rapid decompression and return stroke device of the multi-station die forging hydraulic pressure machine comprises an upper crossbeam, an operating platform, guide pillars, a sliding block and a master cylinder. Four corners of the upper crossbeam are connected with four corners of the operating platform through the guide pillars. The sliding block which fits in with the guide pillars in a sliding mode is arranged below the upper crossbeam. The sliding block is driven by the master cylinder which is arranged on the upper crossbeam. A hydraulic pressure station which is arranged on one side of the operating platform feeds liquid and drives the master cylinder. The upper crossbeam is provided with an upper fuel tank. A prefill valve is arranged between the upper fuel tank and an upper cavity of the master cylinder. The rapid decompression and return stroke device of the multi-station die forging hydraulic pressure machine is characterized by further comprising a low-pressure control pump station which is arranged on the upper crossbeam. The low-pressure control pump station provides oil pressure for the prefill valve, therein the oil pressure is used for communicating. A decompression component is arranged between the prefill valve and the master cylinder. When the rapid decompression and the rapid return stroke are processing, a high pressure of the upper cavity of the master cylinder is dropped into a medium pressure thereof through the decompression component, and then the low-pressure control pump station communicates with the prefill valve, thereby rapidly decompressing, finally hydraulic oil of the upper cavity of the master cylinder is quickly discharged.
Description
Technical field
The utility model relates to a kind of multi-functional position stamp forging hydraulic press, particularly a kind of multi-functional position stamp forging hydraulic press quick pressure releasing, return facilities.
Background technology
The multi-functional position stamp forging hydraulic press is used for the compacting power station valve, and master cylinder carries out feed flow by being located at ground Hydraulic Station, and hydraulic press need to be opened fast prefill valve, thereby hydraulic oil is discharged fast in quick pressure releasing and quick return technological action.Directly by Hydraulic Station control, its shortcoming is: oil circuit is longer for traditional check valve hydraulic control oil circuit, and decompression rate is slower, prefill valve is opened slower, and large owing to building pressure pressure, and prefill valve is difficult for opening, therefore quick pressure releasing and quick return are subject to certain impact, have reduced compacting efficient.
