Abstract
The utility model discloses a forge quick release hydraulic system of hydraulic press, including magnetic ball valve, inserted valve A, choke valve A, choke valve B, one -way throttle valve, inserted valve B, choke valve A connects magnetic ball valve, magnetic ball valve connects inserted valve A, choke valve B and choke valve A parallel connection, choke valve B connects one -way throttle valve, one -way throttle valve is connected in parallel by a choke valve C and a check valve and forms, one -way throttle valve connects inserted valve B. The system adopts magnetic ball valve to control release hydraulic circuit, adjusts through the opening degree of restriction of the stroke to the inserted valve and choke valve, realizes the release steady, that do not have the impact to the hydraulic press, but wide application in the quick release hydraulic circuit of hydraulic presses such as extruder.
Description
Technical field
The utility model relates to technical field of hydraulic, particularly a kind of forge oil press fast pressure relief hydraulic system.
Background technique
In forging process, for large tonnage oil hydraulic press, in the course of the work, often due to oil hydraulic press hydraulic system release characteristic Problems existing, the vibrations causing instantaneous generation strong and the huge sound.For forge oil press, not only require that hydraulic system release is steady, also need to embody its rapidity, guarantee to realize higher forging times, improve its working efficiency, therefore the release characteristic of oil hydraulic press becomes the important indicator weighing forge oil press performance.
Model utility content
It is low that technical problem to be solved in the utility model is to provide a kind of cost, can realize forge oil press fast pressure relief hydraulic system that is steady, fast pressure relief.
For solving the problems of the technologies described above, the utility model have employed a kind of forge oil press fast pressure relief hydraulic system, comprise Solenoid ball valve, cartridge valve A, throttle valve A, throttle valve B, one-way throttle valve, cartridge valve B, described throttle valve A connects Solenoid ball valve, described Solenoid ball valve connects cartridge valve A, described throttle valve B and throttle valve A are connected in parallel, described throttle valve B connects one-way throttle valve, described one-way throttle valve is composed in parallel by a throttle valve C and an one-way valve, and described one-way throttle valve connects cartridge valve B.
The utility model adopts Solenoid ball valve to control release oil hydraulic circuit, by regulating the stroke restriction of cartridge valve and the opening degree of throttle valve, realize stable, the shock-free release to oil hydraulic press, can the oil hydraulic press fast pressure relief oil hydraulic circuits such as extrusion press be widely used in.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, oil hydraulic press master cylinder, 2, Solenoid ball valve, 3, cartridge valve A, 4, throttle valve A, 5, throttle valve B, 6, throttle valve C, 7, one-way valve, 8, cartridge valve B.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
With reference to Fig. 1, for a kind of forge oil press fast pressure relief hydraulic system, comprise Solenoid ball valve 2, cartridge valve A3, throttle valve A 4, throttle valve B5, one-way throttle valve, cartridge valve B8, described throttle valve A 4 connects Solenoid ball valve 2, described Solenoid ball valve 2 connects cartridge valve A3, and described throttle valve B5 and throttle valve A 4 are connected in parallel, and described throttle valve B5 connects one-way throttle valve, described one-way throttle valve is composed in parallel by a throttle valve C6 and an one-way valve 7, and described one-way throttle valve connects cartridge valve B8.
Working principle of the present utility model is: when Solenoid ball valve 2 is energized, cartridge valve A3 opens fast, oil hydraulic press master cylinder 1 realizes one-level release by throttle valve B, cartridge valve A3, simultaneously, cartridge valve B8 control chamber pressure drop, when pressure drop to cartridge valve B8 open close on value time, cartridge valve B8 is under upper and lower differential pressure action, slow unlatching, oil hydraulic press master cylinder 1 realizes secondary release; Wherein, throttle valve A 4, throttle valve B5 are for regulating the closing velocity of cartridge valve A3, cartridge valve B8.
