Abstract
The utility model provides a vulcanizing machine; the utility model in specific is a vulcanizing machine which makes the pressure adapt to the loop control and surge check valve; the structure comprises a main cylinder and an auxiliary cylinder; the main cylinder is connected with an electromagnetic reversing valve V3 and the auxiliary cylinder is connected with an electromagnetic reversing valve V2; the main cylinder is also connected with a surge check valve V6 and the surge check valve V6 is connected with a pilot electromagnetic overflow valve V1 by an electromagnetic reversing valve V4; a check valve V5 is connected between the main cylinder and the electromagnetic reversing valve V3. Compared with the prior art, the utility model of a vulcanizing machine, which makes the pressure adapt to the loop control, and surge check valve boasts of rational design, simple structure, low production cost and stable operation.
Description
Technical field
The utility model relates to a kind of vulcanizer, and a kind of vulcanizer of working pressure adaptation loop control prefill valve specifically is provided.
Background technology
Two-step action is generally used in vulcanizer system die sinking under the prior art: discharge high pressure with low discharge earlier, again with big flow die sinking.When using the action of low discharge release, be easy to generate the jet sound of long period high pressure liquid stream, when after release is finished, converting big flow die sinking to, then because electrical equipment action conversion causes the sudden change of hydraulic pressure flow easily, from but the machine fluctuation of service.
Summary of the invention
The utility model is at above deficiency, provide a kind of reasonable in design, simple in structure, production cost is low, the vulcanizer of the working pressure adaptation loop that operates steadily control prefill valve.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of vulcanizer of working pressure adaptation loop control prefill valve, comprise master cylinder and auxiliary cylinders, be connected with solenoid directional control valve V3 on the described master cylinder, be connected with solenoid directional control valve V2 on the auxiliary cylinders, also be connected with on the described master cylinder towards liquid valve V6, connect guide's electromagnetic relief valve V1 towards liquid valve V6 by solenoid directional control valve V4, also be connected with check valve V5 between described master cylinder and the solenoid directional control valve V3.
The pressure of guide's electromagnetic relief valve V1 control system.
The quick acting of solenoid directional control valve V2 control auxiliary cylinders.
The high pressure of solenoid directional control valve V3 control master cylinder moves at a slow speed.
Opening of solenoid directional control valve V4 control prefill valve.
The pressurize of check valve V5 control master cylinder.
The quick oil inlet and oil return of prefill valve V6 control master cylinder.
The vulcanizer of a kind of working pressure adaptation loop control prefill valve of the present utility model uses very little flow to control the opening speed of prefill valve, simultaneously the fluid of low discharge is used to control the pressure of whole system, the time-delay that cooperates the time-delay of the hydraulic pressure reaction of Small Flow Control prefill valve when opening fully to come control system pressure to rise again, thus reach the purpose stably of control vulcanizer die sinking.And the respective outer side edges of utilizing each valve used speed governing structure of relief valve, hydraulic pressure time-delay structure, thereby do not increase cost.
This system is directly control prefill valve release and die sinking, and the opening amount of prefill valve was directly proportional with the time of electrical equipment action, so the flow of its release can not produce sudden change during release, machine is not easy generation and shakes.Because the bore of prefill valve is big, the speed of release is fast, only produces the jet sound of short time when release.When changeing quick die sinking, after the spool stroke of the prefill valve of this system's control put in place, the pressure of system rose, and the pulling force of oil cylinder is strengthened, thereby carry out quick acting.Also do not have the sudden change of pressure and flow in this action transfer process, can guarantee the stable of die sinking.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of structure principle chart of vulcanizer of working pressure adaptation loop control prefill valve.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Provide a most preferred embodiment below:
As shown in Figure 1, a kind of vulcanizer of working pressure adaptation loop control prefill valve, comprise master cylinder 1 and auxiliary cylinders 2, be connected with solenoid directional control valve V3 on the described master cylinder 1, be connected with solenoid directional control valve V2 on the auxiliary cylinders 2, also be connected with on the described master cylinder 1 towards liquid valve V6, connect guide's electromagnetic relief valve V1 by solenoid directional control valve V4, also be connected with check valve V5 between described master cylinder 1 and the solenoid directional control valve V3 towards liquid valve V6.
The operation principle of the vulcanizer of a kind of working pressure adaptation loop control prefill valve of the present utility model is realized by V1, V4, V6 interoperation.After master cylinder 1 was squeezed into high pressure, machinery requirement steadily made master cylinder 1 descend fast.The process of action is: solenoid directional control valve V4 energising this moment makes towards liquid valve V6 control mouthful oil-feed, owing to have high pressure in the master cylinder 1, needs high-pressure opening during unlatching.At this moment, the pressure of the control mouth of guide's electromagnetic relief valve V1 rises, and opens prefill valve V6, makes master cylinder 1 release.Release is simultaneously because master cylinder 1 pressure descends, and the thrust that the control nonreturn valve core of prefill valve V6 is opened reduces, and the pressure of control mouth reduces, and causes that the control mouth pressure of the master of system overflow valve reduces, and the pressure of whole system is reduced.At this moment prefill valve V6 opens, and master cylinder 1 descends (in this principle illustration for deadweight descends, can also this principle being improved to the auxiliary decline at a slow speed of auxiliary cylinders 2).After prefill valve V6 opened fully, the pressure of prefill valve V6 control mouthful rose, and the driving pressure of main overflow valve rises, and master cylinder 1 is descended fast.There is not the secondary action of electrical equipment in this process, and makes this action contrast other machines of machine aspect vibrating noise, have very big advantage.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
