Abstract
The invention discloses an exhaust pipe bending machine. The exhaust pipe bending machine comprises a rotating disc, a rolling wheel seat and an exhausting clip, wherein a pipe bending groove is rotatably formed in the rotating disc by virtue of a rotating shaft, a thread groove is formed in the rotating disc, a screw rod is arranged on the thread groove, a rotating handle is hinged to the end part of the screw rod, and a connecting rod is mounted on the handle; a trapezoid-shaped groove is formed in the rolling wheel seat, the end part of the connecting rod is arranged in the trapezoid-shaped groove in a sliding manner, a plurality of rolling wheels are mounted in the rolling wheel seat, and guiding grooves matched with the pipe bending groove are formed in the rolling wheels. When the rotating handle is pressed downwards, the connecting rod slides for a certain distance in the trapezoid-shaped groove so as to guarantee equal force on the rolling wheel seat; by mounting the rolling wheels on the rolling wheel seat, the contact area between the guiding groove and a bending part of an exhaust pipe is increased, and the equal force at the bending part is guaranteed, so that the phenomenon that the exhaust pipe is directly bent or cracks occur at the bending part of the exhaust pipe is reduced, and the rejection rate of the exhaust pipe is reduced.
