Abstract
The utility model provides a device with a function of guaranteeing normal operation of a hydraulic system of a high-speed forging hydraulic press. The device comprises a main cylinder liquid inlet valve and a return cylinder liquid inlet valve. The outlet of the main cylinder liquid inlet valve is communicated with a main cylinder. The outlet of the return cylinder liquid inlet valve is connected with a return cylinder. The device further comprises a low-pressure oil source which is respectively connected with the outlet of the main cylinder liquid inlet valve and the outlet of the return cylinder liquid inlet valve through different pipelines. When the device is used, hydraulic oil in the low-pressure oil source flows to the outlet of the main cylinder liquid inlet valve and the outlet of the return cylinder liquid inlet valve through one-way valves. The device has the advantages that oil supplement is performed on the pipeline connected with the outlet of the main cylinder liquid inlet valve when the main cylinder liquid inlet valve is closed instantly, 'cavitation' and 'erosion' of the outlet of the main cylinder liquid inlet valve are avoided, damage to hydraulic components is reduced, pipeline vibration and noise are lowered, and normal operation of the hydraulic system of the high-speed forging hydraulic press is guaranteed.
Description
Technical field
The utility model belongs to hydraulics field, relates to master cylinder liquid feed valve and pipeline thereof in the high speed forging hydraulic press of a kind of material pressure processing, particularly a kind of device that can ensure the normal work of high speed forging hydraulic press hydraulic system.
Background technique
The master cylinder liquid feed valve of high speed forging hydraulic press hydraulic system is placed in basement, from master cylinder away from.Under press rapid forge state, the master cylinder liquid feed valve switch frequency is very high, in the time that master cylinder liquid feed valve moment closes, inertial force effect during due to running of hydraulic power oil, fluid in master cylinder liquid feed valve export pipeline still flows forward, causes master cylinder liquid feed valve outlet port easily to form vacuum, occurs " air pocket ", " cavitation erosion " phenomenon, infringement hydraulic element, produce pipe vibration and noise.
Summary of the invention
The purpose of this utility model is to provide a kind of device that can ensure the normal work of high speed forging hydraulic press hydraulic system, prevents that the outlet port of valve when master cylinder liquid feed valve moment closes from forming vacuum.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of device that can ensure the normal work of rapid forge hydraulic parts hydraulic system, comprises master cylinder liquid feed valve and kicker cylinder liquid feed valve; The outlet of master cylinder liquid feed valve is communicated with master cylinder, the outlet of kicker cylinder liquid feed valve is connected with kicker cylinder, this device also comprises low pressure oil sources, by different pipelines, outlet is connected low pressure oil sources with kicker cylinder liquid feed valve with the outlet of master cylinder liquid feed valve respectively, on these two pipelines, be respectively equipped with one-way valve, when use, the hydraulic oil in low pressure oil sources flows to the outlet of master cylinder liquid feed valve and the outlet of kicker cylinder liquid feed valve by one-way valve.
The pipeline that connects low pressure oil sources and the outlet of master cylinder liquid feed valve is provided with the first one-way valve, and when use, the hydraulic oil in low pressure oil sources flows to the outlet of master cylinder liquid feed valve by the first one-way valve.
The pipeline that connects low pressure oil sources and the outlet of kicker cylinder liquid feed valve is provided with the second one-way valve, and when use, the hydraulic oil in low pressure oil sources flows to the outlet of kicker cylinder liquid feed valve by the second one-way valve.
The utility model device increases one-way valve on the export pipeline of master cylinder liquid feed valve, master cylinder liquid feed valve is instantaneous while closing to exporting repairing in the pipeline being connected with master cylinder liquid feed valve, avoid the outlet of master cylinder liquid feed valve to occur " air pocket ", " cavitation erosion " phenomenon, reduce the infringement of hydraulic element, reduce pipe vibration and noise.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model device.
In figure: 1. the first one-way valve, 2. master cylinder liquid feed valve, 3. low pressure oil sources, 4. kicker cylinder liquid feed valve, 5. oil hydraulic pump, 6. motor, 7. fuel tank, 8. kicker cylinder, 9. master cylinder, 10. the second one-way valve.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, the utility model device, comprises master cylinder liquid feed valve 2 and kicker cylinder liquid feed valve 4; The outlet of master cylinder liquid feed valve 2 is communicated with master cylinder 9 and low pressure oil sources 3 respectively, and the pipeline that connects 2 outlets of master cylinder liquid feed valve and low pressure oil sources 3 is provided with the first one-way valve 1; The outlet of kicker cylinder liquid feed valve 4 is connected with low pressure oil sources 3 with kicker cylinder 8 respectively, and the pipeline that connects 4 outlets of kicker cylinder liquid feed valve and low pressure oil sources 3 is provided with the second one-way valve 10; The liquid entering hole of the liquid entering hole of master cylinder liquid feed valve 2 and kicker cylinder liquid feed valve 4 is communicated with oil hydraulic pump 5 respectively, and oil hydraulic pump 5 is connected with fuel tank 7 with motor 6 respectively.
In high speed forging hydraulic press hydraulic system, master cylinder liquid feed valve 2 and kicker cylinder liquid feed valve 4 are placed in basement, from master cylinder 9 and kicker cylinder 8 away from, under press rapid forge state, the switch frequency of master cylinder liquid feed valve 2 and kicker cylinder liquid feed valve 4 is very high, while closing in liquid feed valve moment, inertial force effect during due to running of hydraulic power oil, fluid in liquid feed valve export pipeline continues to flow forward, make master cylinder liquid feed valve 2 outlet ports and kicker cylinder liquid feed valve 4 outlet ports easily form vacuum, occur " air pocket ", " cavitation erosion " phenomenon, infringement hydraulic element, produce pipe vibration and noise.Therefore, export nearer place and add the one-way valve of little latus rectum at master cylinder liquid feed valve 2 outlet and kicker cylinder liquid feed valve 4, the latus rectum of one-way valve employing 10mm; Be connected on the low pressure oil sources 3 with certain pressure by little latus rectum pipeline, when press is forged soon, when master cylinder liquid feed valve 2 is closed rapidly, in the instantaneous formation vacuum of exit region of master cylinder liquid feed valve 2, now can utilize the pressure of low pressure oil sources 3, realize automatic repairing by repairing one-way valve to the outlet of master cylinder liquid feed valve 2, so just can avoid master cylinder liquid feed valve 2 outlet ports to occur the phenomenon of " air pocket ", " cavitation erosion ", thereby reduce the infringement of hydraulic element, reduced pipe vibration and noise.Therefore, in hydraulic system, by increasing pressure repairing pipeline in large diameter directional valve outlet port, can reduce cavitation phenomenon, mitigation system vibration and noise, protection hydraulic system.
