Description
Technical field
The present invention relates to a kind of low-power consumption big flow high-speed switch valve, the high speed for being especially adapted for use in hydraulic High-speed punch press is opened
Close valve.
Background technology
Hydraulic High-speed punch press is the advanced basic process unit of modern manufacturing industry, and it relies on hydraulic pressure main control valve to control hydraulic cylinder
Realize that high speed stamping is acted.Hydraulic pressure main control valve directly determines stamping press, punching stroke and the punching press frequency of hydraulic press.
At present, hydraulic High-speed punch press generally uses servo valve as hydraulic pressure main control valve.However, due to the valve port pressure of servo valve
Damage larger, the service behaviour of hydraulic High-speed punch press is restricted.Existing hydraulic High-speed punch press is in 1000 beats/min of high frequency punching press operating modes
Under stamping press be typically not greater than 30 tons, punching press stroke there was only several millimeters.Therefore, under high frequency punching press operating mode, existing hydraulic pressure
High velocity ram machine is only applicable to the processing such as punching, punching of thin metal plate material, and cannot be applied to thicker metal plate material, the deep draw of larger stroke
Deng processing, the range of application of hydraulic High-speed punch press is seriously limited.
The content of the invention
It is an object of the invention to provide a kind of low-power consumption big flow high-speed switch valve, to be applied to hydraulic High-speed punch press
Hydraulic control system, realizes the big stroke high speed stamping of heavy duty.
The technical solution adopted for the present invention to solve the technical problems is：
The present invention includes valve pocket, valve element, differential oscillating cylinder and high speed switching valve.Described valve element is arranged in valve pocket, structure
Into the main valve structure of rotary valve；Valve element is radially provided with the straight-through runner of three valve elements, and the straight-through runner of three valve elements is along axle
Line direction is sequentially distributed, and the center line of the straight-through runner of two neighboring valve element has equal distance in the axial direction；Two side valves
The area of passage of the straight-through runner of core is equal, and both area of passage sums are equal to the area of passage in middle valve element straight through flow road；It is described
Valve pocket be provided with the straight-through runner of valve pocket in the corresponding position of the straight-through runner of valve element, it has identical shape with valve element straight through flow road
Shape；The fluid flow direction in valve element straight through flow road leads directly to the fluid flow direction phase of runner with both sides valve element in the middle of described valve element
Instead；The import of the straight-through runner of both sides valve element and the outlet in middle valve element straight through flow road, the outlet of the straight-through runner of both sides valve element
With the inlet communication in middle valve element straight through flow road；The rotation of described valve element is controlled by differential oscillating cylinder, differential oscillating cylinder
Rotation direction is then controlled by a high speed switching valve of two four-ways.
The invention has the advantages that：
（1）When high-speed switch valve is in open state, runner is straight-through form of tubes, and valve port excessively stream crushing is small, can be with
Realize that the low-power consumption big flow of fluid is through-flow.
（2）Fluid flow direction in spool end runner is with intermediate flow channel conversely, the area of passage sum of end runner
Equal to intermediate flow channel area of passage, and the two end runners are symmetrical on intermediate flow channel in axis direction, above-mentioned to be designed to
Reduce the radial imbalance force suffered by valve element as far as possible.
（3）Differential oscillating cylinder and high speed switching valve constitute power amplifying system, it is possible to achieve the small power high speed of valve element drives
It is dynamic.
（4）The simple shape of valve element and valve pocket runner, it is easy to process, low cost.
Brief description of the drawings
Fig. 1 is valve port open mode hydraulic schematic diagram of the invention.
Fig. 2 is valve port closed mode hydraulic schematic diagram of the invention.
In figure：1.1st, valve pocket, 1.2, valve element, 2, differential oscillating cylinder, 3, high speed switching valve.
Specific embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in figure 1, the present invention is made up of valve pocket 1.1, valve element 1.2, differential oscillating cylinder 2 and high speed switching valve 3.Valve element
1.2 are arranged in valve pocket 1.1, constitute the main valve structure of rotary valve.Valve element 1.2 is radially provided with three straight-through runners, should
Three runners are sequentially distributed in the axial direction, and the center line of two neighboring runner has equal distance in the axial direction；Two
The area of passage of individual end runner is equal, and both area of passage sums are equal to the area of passage of intermediate flow channel.Valve pocket 1.1 is in valve element
The corresponding position of 1.2 runners is provided with straight-through runner, and it is of similar shape with the runner of valve element 1.2.The intermediate flow channel of valve element 1.2
Fluid flow direction it is opposite with the fluid flow direction of two end runners.The inlet and outlet of three runners is respectively communicated with.
The rotation of valve element 1.2 is controlled by differential oscillating cylinder 2, and the rotation direction of differential oscillating cylinder 2 is then by two high speeds for four-way
Switching valve 3 is controlled.
As shown in figure 1, high speed switching valve 3 is operated in left position, the hydraulic oil of guide's high pressure fuel source drives differential oscillating cylinder 2 inverse
Hour hands rotate, and then rotational valve core 1.2, the runner of valve element 1.2 and valve pocket 1.1 is in complete connected state, system high pressure oil
The hydraulic oil in source flows to executive component by the runner of valve element 1.2 and valve pocket 1.1.Now, speed-sensitive switch involved in the present invention
Valve is in open mode.
As shown in Fig. 2 high speed switching valve 3 is operated in right position, the hydraulic oil of guide's high pressure fuel source drives the differential wink of oscillating cylinder 2
Hour hands rotate, and then rotational valve core 1.2, the runner of valve element 1.2 and valve pocket 1.1 is in not connected state.Now, institute of the present invention
The high-speed switch valve being related to is closed.
