Abstract
The invention discloses a flow converter of a double-united oil pump of a hydraulic bending machine, comprising a main converter body, wherein the main converter body is provided with a first input port, a second input port, an output port and a return port, and a cavity is arranged in the main converter body and is respectively communicated with the first input port, the second input port and the output port. A transition mandrel is arranged in the cavity, and the circumferential side surfaces of the transition mandrel are respectively provided with a first gap and a second gap. The first gap is communicated with the return port by a transition hole, and the first input port and the second input port are communicated with the output port by the second gap. When the hydraulic bending machine needs the low speed, one input port can be adopted to transmit hydraulic oil to a hydraulic system, and the hydraulic oil in the other input port flows back to an oil tank by the transition hole in the first gap. Accordingly, the flow converter reduces the load of the hydraulic system, avoids the energy waste and the damage of hydraulic system components, prevents the temperature of the hydraulic system from rising and ensures the good performance of the hydraulic bending machine.
