Hydraulic system principle diagram of the induction pipe bending machine, is composed of 9 hydraulic cylinder and the 2 hydraulic motor component. The main clamp cylinder on a pipe always guarantee that the pipeline fixed on a rotary arm through the fixture, ensure pipe according to the predetermined radius bending; guide clamp cylinder auxiliary pinch effect, also has the guidance and the support function; promote the oil cylinder in the bend tube, to provide power for the pipe bending machine; auxiliary clamping cylinder is fixed on the Elbow push trolley on the elbow, prevent pipeline vibration in advance; positioning clamping cylinder of the main chuck positioning on the rocker rail, to prevent the work due to stress and mobile; positioning hydraulic motor, realize mobile arm workbench; reset motor is at the end of the rocker arm at the elbow, reset. In the hydraulic system of the tube bending machine, bending the main clamping cylinder, guide clamp cylinder, auxiliary clamping cylinder, propulsion cylinder and positioning clamping cylinder adopts a hydraulic control one-way valve lock, reducing the loss of pressure, in order to ensure reliable clamping, bending action of the pipe bending process.
Power outages, positioning and clamping. Then press the start button, the programmable logic controller (PLC) are performed automatically under the control of the following actions.
