Description

Technical Field

[0001] The utility model relates to the technical field of pipe benders, and particularly relates to a swing arm tooling for a pipe bender. Background Technique

[0002] A pipe bender is a mechanical device used for bending metal pipes of various specifications and is widely used in industries such as automobiles and construction.

[0003] The existing pipe bender includes components such as a frame and a swing arm. A rotating shaft arranged in the vertical direction is provided on the frame. The rotating shaft is rotatably connected to the frame through a bearing. The swing arm is connected to the rotating shaft, and the swing arm can swing in the horizontal direction through the rotating shaft. During pipe bending operation, one side of the bending position of the pipe is clamped on the frame, and the other side of the bending position of the pipe is clamped on the swing arm. The bending of the pipe is achieved through the swing of the swing arm.

[0004] In practice, a shaft hole is provided on the swing arm. The swing arm is connected to the rotating shaft on the frame through the shaft hole on it. The shaft hole and the rotating shaft are fixedly connected through interference fit to realize the fixed connection between the swing arm and the rotating shaft.

[0005] During the actual assembly process of the swing arm, since the shaft hole on the swing arm and the rotating shaft are in interference fit, a certain pressure is required to press the rotating shaft into the shaft hole on the swing arm. Usually, it is necessary to repeatedly hammer with a rubber hammer to install the rotating shaft into the shaft hole. This assembly method is time-consuming and laborious, and it is easy to damage the swing arm and the rotating shaft during the hammering process. Summary of the Invention
