Embodiment Construction
[0034] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0035] Such as figure 1 As shown, the present invention discloses a control system of a hydraulic pump 30 integrated with an engine 40. The control system includes: a hydraulic cylinder 10, a hydraulic pump 30, an engine 40, a reversing valve 50, a first solenoid valve 21, a second The solenoid valve 22, the third solenoid valve 23, the first pressure sensor 81, the second pressure sensor 82, the controller 60 and the operating handle.
[0036] The hydraulic cylinder 10 is a direct acting part that pressurizes the wires to bond the wires, the piston rod 13 of the cylinder 10 bonds the two wires by extending and pressing the two wires, and moves away from the wires by retracting . Specifically, the hydraulic cylinder 10 has a ro...

The invention discloses a control system for a hydraulic pump integrated with an engine. The control system for the hydraulic pump integrated with the engine comprises a hydraulic cylinder, the hydraulic pump, a reversing valve, the engine, a first pressure sensor, a first electromagnetic valve, a second electromagnetic valve and a controller. The reversing valve is at least provided with a firstposition for enabling hydraulic oil provided by the hydraulic pump to enter a rodless cavity and enabling hydraulic oil in a rod cavity to reflow to an oil tank, and a second position for enabling thehydraulic oil in the rodless cavity to reflow to the oil tank and enabling the hydraulic oil provided by the hydraulic pump to enter the rod cavity; the engine is used for providing mechanical powerfor the hydraulic pump; the first pressure sensor is used for measuring the pressure of the hydraulic oil in the rodless cavity; the first electromagnetic valve is powered so as to switch the reversing valve to the first position; the second electromagnetic valve is powered so as to switch the reversing valve to the second position; and the controller is configured to be used for acquiring a pressure value measured by a first pressure sensor, so that when the pressure of the hydraulic oil in the rodless cavity is higher than the first setting pressure, the controller controls the second electromagnetic valve to power on and the first electromagnetic valve to power off.
Description
technical field [0001] The invention relates to the technical field of wire crimping, in particular to a control system of a hydraulic pump used to provide pressure for the pressure drop of wires. Background technique [0002] In the prior art, the crimping of the wires is realized by hydraulically providing pressure, and the equipment for providing pressure to the wires usually includes a hydraulic cylinder and a control system for controlling the expansion and contraction of the hydraulic cylinder to implement depressurization of the wires. [0003] The above-mentioned equipment in the prior art has the following defects: [0004] The control system only controls the pressure applied to the wire by controlling the telescoping stroke of the piston rod, so that the pressure on the wire is uncertain, and overpressure or undervoltage often occurs, that is, the applied pressure is insufficient or excessive. Contents of the invention [0005] In view of the above-mentioned te...
