Abstract
The utility model discloses a flow transducer for a double-ply pump of a hydraulic bending machine. The flow transducer comprises a transducer main body, wherein a first input port, a second input port, an output port and a liquid return port are arranged on the transducer main body, the transducer main body is provided with a cavity which is communicated with the first input port, the second input port and the output port, a transition core shaft is arranged inside the cavity, a first notch and a second notch are formed on the side surface at the circumference of the transition core shaft respectively, the first notch is communicated with the liquid return port through a transition hole, and the first and the second input ports can be communicated with the output port through the second notch. When the hydraulic bending machine needs a lower speed, one of the input ports can be utilized to convey hydraulic oil to a hydraulic system, and the hydraulic oil in the other input port flows back to an oil tank through the transition hole of the first notch, so as to reduce the loading of the hydraulic system, avoid energy waste and the damage on elements of the hydraulic system, prevent the temperature rise of the hydraulic system, and ensure the good performance of the hydraulic bending machine.

Technical field
The utility model relates to a kind of flow converter of double-united oil pump of hydraulic bending machine.
Background technique
Double-united oil pump in the hydraulic bending machine that uses needs flow converter to control the movement velocity of the flow and then the control hydraulic bending machine of hydraulic oil in the input hydraulic pressure device usually now.Present this flow converter generally is divided into several gears, and the conversion of flow is realized in the corresponding hydraulic oil inlet opening of each gear by the hydraulic oil inlet opening of selecting different bores.Yet, thereby this flow converter is to change the effect that the flow of hydraulic oil in the hydraulic pressure installation reaches speed governing by the mode of forcing throttling, no matter which kind of speed hydraulic bending machine selects for use, hydraulic system all is in full load condition, cause energy waste, the shortening in working life of hydraulic system element, the temperature of hydraulic system raises, and influences the performance of hydraulic bending machine.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of flow converter of double-united oil pump of hydraulic bending machine of saving the energy and protecting the hydraulic system element, ensures the superperformance of hydraulic bending machine.
In order to solve the problems of the technologies described above, flow converter of double-united oil pump of hydraulic bending machine of the present utility model, comprise changer body, described changer body is provided with first, second inlet opening, delivery outlet and liquid return hole, has cavity in the changer body, this cavity is communicated with first, second inlet opening and delivery outlet respectively, be provided with the transition mandrel in the cavity, the circumference side of transition mandrel is respectively equipped with first, second breach, this first breach is communicated with liquid return hole by transitional pore, and second breach can be communicated with first, second inlet opening and delivery outlet.
As improvement of the technical scheme, the both sides of described changer body are respectively arranged with first, second pressure regulator valve that is used for regulating described first, second inlet opening input liquid pressure.
As further improvement in the technical proposal, described changer body outside is equipped with the handle that is connected and controls its rotation with transition mandrel end.
The beneficial effects of the utility model are: this flow converter of double-united oil pump of hydraulic bending machine is owing to adopted said structure, when hanging down, the speed of hydraulic bending machine needs can adopt one of them inlet opening that hydraulic system is carried out delivery hydraulic pressure oil, hydraulic oil in another inlet opening is back to fuel tank by the transitional pore in first breach, reduce the load of hydraulic system, avoid the waste of the energy and the damage of hydraulic system element, the temperature that prevents hydraulic system raises, and ensures the superperformance of hydraulic bending machine.
