Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of hydraulic system of slider of hydraulic press release mechanism, comprise the hydraulic cylinder 10 that is connected with the ratchet 20 of release mechanism by its piston rod 11, the port of export of hydraulic pump 30 is provided with check valve 60, and the port of export of check valve 60 links to each other through the oil-in of magnetic valve 80 with hydraulic cylinder 10.
The ratchet 90 of the ratchet 20 of release mechanism, hydraulic cylinder 10, piston rod 11, spring 12 and slide block is existing in the prior art among Fig. 1 addresses, in conjunction with the technical solution of the utility model, when the ratchet on ratchet 20 that needs release mechanism and the slide block 90 breaks away from mutually, at first make on the slide block and move, hydraulic pump 30 starts then, hydraulic oil enters hydraulic cylinder 10 inside through the oil-in of check valve 60, magnetic valve 80, hydraulic cylinder 10 successively, piston rod 11 pressurizeds of hydraulic cylinder 10 move, and the ratchet 90 that drives simultaneously on ratchet 20 and the slide block breaks away from; When the ratchet 90 on the ratchet 20 that needs release mechanism and the slide block against each other the time, magnetic valve 80 actions, hydraulic oil in the hydraulic cylinder 10 flow back into fuel tank by oil-in, magnetic valve 80 successively, spring in the release mechanism 12 actions simultaneously, push ratchet 20 to slide block one side, finally make ratchet 20 and ratchet 90 lean, thereby finished fixing slide block.
When the ratchet on ratchet 20 that needs release mechanism and the slide block 90 broke away from mutually, magnetic valve 80 was in position, a left side, magnetic valve 80 connection check valves 60 and hydraulic cylinder 10, and hydraulic oil can be pumped in the hydraulic cylinder 10 smoothly; When the ratchet 90 on the ratchet 20 that needs release mechanism and the slide block against each other the time, magnetic valve 80 moves to right position, magnetic valve 80 is communicated with fuel tank and hydraulic cylinder 10, hydraulic oil self-hydraulic cylinder 10 under the effect of spring 12 flow back into fuel tank by magnetic valve 80, thereby has realized the purpose of this utility model exactly.
In order to guarantee the safe operation of hydraulic system, as shown in Figure 1, described hydraulic pump 30 is connected with the release branch road with pipeline between the check valve 60, and the release branch road is provided with overflow mechanism 50.
Overflow mechanism also has multiple choices, such as adopting overflow valve, as preferred version of the present utility model, as shown in Figure 1, described overflow mechanism 50 is made up of outer controlled overflow valve 51 and magnetic valve 52, the outside control mouth of overflow valve 51 is connected by control piper with the oil-in of magnetic valve 52, and described overflow valve 51 all is communicated with fuel tank with the oil-out of magnetic valve 52.
Described outer controlled overflow valve 51 and the magnetic valve 52 common electrodynamic type overflow valve groups of forming, when magnetic valve 52 is opened, hydraulic oil can directly flow back into fuel tank by magnetic valve 52, when magnetic valve 52 cuts out, hydraulic oil acts on outer controlled overflow valve 51, makes overflow valve 51 actions and flow back into fuel tank after reaching certain pressure.Hence one can see that, and this electrodynamic type overflow valve group both can realize the function of pipeline overflow, can also realize the function with the direct off-load of pipeline, thereby guaranteed the safe operation of this hydraulic system.
