Opposite, when conversion another side shifting (in Fig. 4 move down) of the control 2 to housing 1, conversion control 2 is located at the Three stations, mobile distance is equal to the diameter for flowing into branch pipe.Oil circuit direction now is:Through hole on the converted control 2 of fluid The second connecting tube 4 is flowed into from fluid intake 21, then is flowed into the second cavity of hydraulic cylinder, the fluid in the first cavity of hydraulic cylinder Through hole from the first connecting tube 3 and conversion control flows to fluid issuing 12.It is specific as follows:
The 4th inflow connecting branch 42 of branch pipe 114 and the 4th is respectively communicated with third through-hole 23;Second connecting branch 31 and One outflow branch pipe 121 respectively with the UNICOM of first through hole 21.The setting causes that fluid flows into branch pipe 114 and flows into third through-hole through the 4th 23, flowed into the second cavity 200b of hydraulic cylinder by the 4th connecting branch 42, the fluid warp in the first cavity of hydraulic cylinder 200a Second connecting branch 31, the outflow branch pipe 121 of first through hole 21 and first flow out.Second circulation in direction in hydraulic cylinder is realized, Piston is pushed back into initial position, piston is retreated.
In the present embodiment, control 2 is changed shaft-like into cylinder.However, the utility model is not limited in any way to this.Yu Qi In its embodiment, it can be flat column to change control 2.
In the present embodiment, switching valve 100 also includes being arranged on housing 1 and driving side of the conversion control 2 to housing 1 Or the actuator 5 of another side shifting.In the present embodiment, actuator 5 is tool in the swivelling cover being arranged on housing 1, swivelling cover Two arc tracks 51 are symmetrical arranged, two arc tracks 51 are relative with two ends of conversion control 2.However, this practicality It is new that this is not limited in any way.Further, the outer surface of actuator 5 has multiple Non-slip materials 52.The setting greatly facilitates The station of user's switch transition control.
It is that, with more preferable intensity, in the present embodiment, swivelling cover also includes being correspondingly arranged with two arc tracks 51 Two reinforcements 53.However, the utility model is not limited in any way to this.
Switching valve 100 is switched over to oil circuit in the bending straightener that the present embodiment is also provided.Hydraulic cylinder 200 and switching valve 100 the first connecting tube 3 is connected with the second connecting tube 4, and hydraulic cylinder 200 includes piston 201, and piston 201 is by hydraulic cylinder Cavity is divided into the first cavity 200a and the second cavity 200b.Straightening component 300 is fixedly connected with hydraulic cylinder 200, straightening component 300 Support 302 including straightening portion 301 and fixed straightening portion 301, straightening portion 301 is connected with the piston 201 in hydraulic cylinder, piston 201 driving straightening portions 301 move.
In the present embodiment, straightening portion includes straightening groove 3011 and ribs 3012, and ribs 3012 is relative with hydraulic cylinder It is arranged on the outside of straightening groove 3011.
In actual use, user can will treat that the workpiece to be added of straightening is placed on straightening groove 3011, will be turned by actuator 5 The conversion control 2 changed in valve 100 is turned on the second station, and the piston 201 in hydraulic cylinder 200 travels forward, by workpiece to be added Upper bending section straightening.For to machined part spacing and be that certain working space is set in straightening, straightening groove is set 3011 two side walls are curved wall, the width of the upper width less than bottom of straightening groove 3011.The setting of ribs 3012 Improve the intensity of straightening groove 3011, the service life of extension straightening groove 3011.After straightening terminates, will be changed by actuator 5 From the second Switch of working position to 3rd station, the piston 201 of hydraulic cylinder is retreated control 2.
In the present embodiment, switching valve is the oil circuit switching valve applied on hydraulic cylinder.However, the utility model is not made to this Any restriction.In other embodiments, the switching valve that the utility model is provided can be used for other fluids, such as the flow direction conversion of water.
In sum, cross and conversion control is set in switching valve, conversion control can be moved along the axis direction perpendicular to housing Move to cause that conversion control is in different stations.Conversion control is in different stations, through hole and fluid intake and stream thereon Connected relation between body outlet will change.When control is changed in the second station, fluid via through holes and first are connected Pipe flows into the first cavity in hydraulic cylinder, and the fluid in the second cavity of hydraulic cylinder flows out through the second connecting tube and through hole, in liquid Fluid circulation in the first direction is realized in cylinder pressure, piston in hydraulic cylinder travels forward.And when conversion control is in the 3rd During station, the second cavity in fluid via through holes and the second connecting tube inflow hydraulic cylinder, the fluid in the first cavity of hydraulic cylinder Flowed out through the first connecting tube and through hole, fluid circulation in a second direction is realized in hydraulic cylinder, piston in hydraulic cylinder is moved back Go back to original position.The conversion control that the switching valve that the utility model is provided need to only change in switching valve is capable of achieving changing for flow direction Become, so as to realize that the automatic of piston in hydraulic cylinder moves forward and backward.Applied on bending straightener, without oil before change Road is designed, and only need to increase a switching valve, not only greatly convenient for users to use, while also significantly reducing cost.
Although the utility model is disclosed above by preferred embodiment, but the utility model is not limited to, it is any Know this those skilled in the art, do not departing from spirit and scope of the present utility model, a little change can be made with retouching, therefore this practicality New protection domain ought be defined depending on claims scope required for protection.
