Abstract
The utility model relates to a flexible speed regulating mechanism for regulating pressing speed of a hydraulic press, which comprises a hydraulic oil cylinder for pushing a slipper and an oil tank. The return stroke cavity of the hydraulic oil cylinder is communicated with the oil tank through a main oil pipe. The flexible speed regulating mechanism is characterized in that a hydraulic lock is arranged on the main oil pipe on the side close to the return stroke cavity of the hydraulic oil cylinder, and a proportional flow cartridge valve is serially connected between the hydraulic lock and the oil tank. The flexible speed regulating mechanism has the advantages that when the slipper speed is changed from fast to slow, the hydraulic lock is unlocked, the opening of the proportional flow cartridge valve is smoothly regulated through gradually changing the electromagnet current that determines the opening of the proportional flow cartridge valve, so as to complete instantaneous switch from fast to slow in a very short time; and hydraulic oil inside the main oil pipe on the side close to the return stroke cavity of the hydraulic oil cylinder realizes smooth transition and small hydraulic impact, so as to reduce the impact force and vibration suffered by slipper and prolong the service life of equipment.
Description
Technical field
The utility model relates to a kind of hydraulic press, the flexible speed adjusting gear of particularly a kind of hydraulic press pressing speed.
Background technology
Relevant by retrieval patent documentation does not retrieve the flexible speed adjusting gear of the hydraulic press pressing speed identical with the utility model structure at present as yet.Hydraulic press is the novel forging equipment that begins to grow up the sixties in 20th century, be mainly used in the cogging of black, non-ferrous metal and the pressure hot-working of free dirk, for guaranteeing compacting efficient, slide block transfers to during soon near material slowly down by system control idle running soon down, when speed was switched by fast commentaries on classics slow moment, the hydraulic jack backhaul intraluminal fluid of control slide block presses oil to release the hurried variation of speed, hydraulic shock is big, and slide block is subjected to great impact power and vibrations, is subjected to great influence the service life of equipment.
The utility model content
The technical problems to be solved in the utility model provides the flexible speed adjusting gear of a kind of hydraulic press pressing speed, makes slide block in or by slow-speed when fast hydraulic oil smooth transition slow by fast commentaries on classics, avoids that creeping appears in slide block, jitter phenomenon.
For solving the problems of the technologies described above, the technical solution of the utility model is: the flexible speed adjusting gear of a kind of hydraulic press pressing speed, comprise the hydraulic jack that promotes slide block, and fuel tank, the backhaul chamber of this hydraulic jack is communicated with fuel tank by main oil pipe, its innovative point is: on the described main oil pipe near hydraulic jack backhaul chamber one side hydraulic lock is installed, and is serially connected with ratio flow inserted valve between hydraulic lock and fuel tank.
Advantage of the present utility model is: when slide block is slow by fast commentaries on classics, hydraulic lock is in open mode, by changing the electromagnet current size of decision ratio flow inserted valve aperture gradually, the level and smooth adjustment of realization ratio flow inserted valve aperture, finish in the extremely short time by fast extremely slow moment switching, near hydraulic oil smooth transition in the one side main oil pipe of hydraulic jack backhaul chamber, hydraulic shock power is little, suffered impulsive force and the vibrations of slide block have been reduced, the service life of having improved equipment.
Description of drawings
Accompanying drawing is the utility model hydraulic press pressing speed flexible speed regulating device structural representation.
The specific embodiment
As shown in drawings, comprise hydraulic jack 1, fuel tank 2, main oil pipe 3, hydraulic lock 4, ratio flow inserted valve 5.
Above-mentioned hydraulic jack 1 is used to promote the slide block uplink and downlink and suppresses action, and its backhaul chamber is communicated with fuel tank 2 by main oil pipe 3.Hydraulic lock 4 is installed in a side in close hydraulic jack 1 backhaul chamber on the main oil pipe 3, and ratio flow inserted valve 5 is serially connected between hydraulic lock 4 and the fuel tank 2.
When slide block is slow by fast commentaries on classics, hydraulic lock 4 is in open mode, by changing the electromagnet current size of decision ratio flow inserted valve 5 apertures gradually, realize the level and smooth adjustment of ratio flow inserted valve 5 apertures, in the extremely short time, finish by fast to slow moment switching.
