Structure and Working Principle of Duct Beader Machine

When duct beader machine bends the pipes, the rocker arm bears circumferential force and resistance moment. The rocker arm's return position is driven by the rocker arm driving device, and the return speed is 2.2r/min. When the turning device of rocker arm adjusts the bending radius, it starts the hydraulic motor of the middle sliding platform, move the worktable of the middle sliding platform, locate the center of the chuck at the prescribed size through the ruler of the sliding platform, close the hydraulic motor, move the small sliding platform through the gear rack mechanism, fix the small sliding platform on the middle sliding platform with the positioning pin, and rotate the top wire. The clamp head is tightened to complete the positioning of the chuck; the large sliding table motor is started and the worktable of the large sliding table is moved to make the center of the chuck coincide with the center of the guide wheel device and close the motor; the clamping cylinder motor is started and the worktable of the large sliding table is clamped to realize the positioning of the worktable (rocker turning center).

When bending the pipe, the rocker arm driving device does not work. The rocker arm rotating device is driven by the main driving device through the pipe fittings and bears the circumferential force and resistance moment. The return position of the rocker arm is driven by the rocker arm driving device. When operating, the electromagnetic clutch is closed, the return hydraulic motor is started, the rocker arm driving device drives the rotation of the rotary device. After the rocker arm is turned back to its original position, the hydraulic motor is closed, the electromagnetic clutch is disconnected and the next action is prepared. Driven by pipe fittings, it bears circumferential force and resistance moment. The return position of the rocker arm is driven by the rocker arm driving device. When operating, the electromagnetic clutch is closed, the return hydraulic motor is started, the rocker arm driving device drives the rotation of the rotary device. After the rocker arm is turned back to its original position, the hydraulic motor is closed, the electromagnetic clutch is disconnected and the next action is prepared.

The overall structure of the machine is characterized by its working principle, with easy operation, automatic input, NC control, very accurate and high efficiency. The bending part is controlled by gear and rack servo motor, and the bending rotation is controlled by servo motor. The bending effect has high precision.
