Abstract
The utility model discloses a core rod rotating hydraulic system. The system is characterized by comprising a solenoid directional valve, a stacked hydraulic control one-way valve, a stacked cavitation-proof valve and a stacked safety valve, wherein the solenoid directional valve is connected with the stacked hydraulic control one-way valve, the stacked hydraulic control one-way valve is connected with the stacked cavitation-proof valve, the stacked cavitation-proof valve is connected with the stacked safety valve, and the solenoid directional valve is also connected with a pilot control speed regulating valve. The core rod rotating hydraulic system has the advantages that the pilot control speed regulating valve is adopted, the core rod rotating (hydraulic control) can be achieved, non-impact low-high speed control is conducted, and positioning can be achieved stably, rapidly and accurately.
Description
Technical field
The utility model relates to a kind of Mandrel Rotating hydraulic system.
Background technology
Collection volume is an important procedure during high line is produced, and wherein Mandrel Rotating (hydraulic control) need carry out shock-free speed speed control system, in order to realize stable, location fast and accurately, hydraulic system in the past realizes this function with a solenoid-operated proportional reversal valve.Because the hydraulic proportional system is very high to the cleannes requirement of fluid, so must add high-precision high pressure filter in the high-pressure pump outlet; And safeguard that ratio system must will have certain understanding to Electrical Control Technology, could solve the problem that occurs in the production process so soon.
Summary of the invention
The purpose of this utility model provides a kind of Mandrel Rotating hydraulic system.
The technical solution adopted in the utility model is:
The Mandrel Rotating hydraulic system, comprise solenoid directional control valve, stacking type hydraulic control check valve, superposing type anti-cavitation valve and superposing type safety valve, described solenoid directional control valve is connected with stacking type hydraulic control check valve, described stacking type hydraulic control check valve is connected with superposing type anti-cavitation valve, described superposing type anti-cavitation valve is connected with the superposing type safety valve, and described solenoid directional control valve also connects the pilot control flow speed control valve.
The utility model has the advantages that: adopt the pilot control flow speed control valve, can realize that Mandrel Rotating (hydraulic control) carries out shock-free speed speed control system, realize stablizing, locating fast and accurately.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, solenoid directional control valve, 2, stacking type hydraulic control check valve, 3, superposing type anti-cavitation valve, 4, the superposing type safety valve, 5, the pilot control flow speed control valve.
The specific embodiment
As shown in Figure 1, Mandrel Rotating hydraulic system of the present utility model, comprise solenoid directional control valve 1, stacking type hydraulic control check valve 2, superposing type anti-cavitation valve 3 and superposing type safety valve 4, described solenoid directional control valve 1 is connected with stacking type hydraulic control check valve 2, described stacking type hydraulic control check valve 2 is connected with superposing type anti-cavitation valve 3, described superposing type anti-cavitation valve 3 is connected with superposing type safety valve 4, described solenoid directional control valve 1 also connects pilot control flow speed control valve 5, adopt pilot control flow speed control valve 5, can realize that Mandrel Rotating (hydraulic control) carries out shock-free speed speed control system, realize stable, locate fast and accurately.
Operation principle:
Desirable Mandrel Rotating, when starting, encoder is to electromagnet YV1 and electromagnet YV3 signal, simultaneously electric, the opening of pilot control flow speed control valve 5 is slowly opened greatly, Mandrel Rotating is adjustable by static extremely quick V1(acceleration); Then at the uniform velocity arrive certain angle (such as 150 °) always, this moment, encoder was to electromagnet YV3 signal, the YV3 dead electricity, again so that the V2(acceleration is adjustable at a slow speed) forward next angle (such as 180 °) to, near this angle (such as 180 °) time, Mandrel Rotating is close to zero, can realize shock-freely accurately putting in place.
This valve is controlled flow with built-in operation of oil cylinde, make executive component when accelerating and slow down, have stably discharge characteristic, can realize shock-free operation, because with the pressure and temperature compensator, can realize stable flow-control, and irrelevant with the variation of load and temperature.
