Description

Technical Field

[0001] The utility model belongs to the technical field of exhaust pipe processing, and more specifically, particularly relates to an exhaust pipe forming and trimming device. Background Art

[0002] When the exhaust elbow is formed, the shape of the exhaust pipe needs to be trimmed by a forming device. When in use, the existing forming device needs to first fix the exhaust pipe with a clamp, and then rotate the force arm to make the pulley on the force arm squeeze the exhaust pipe. At this time, the exhaust pipe can be deformed under the joint action of the pulley and the top wheel.

[0003] For example, CN208787252U discloses an exhaust pipe bending and forming device, comprising a workbench, a rotating shaft vertically installed on the workbench, and a top wheel sleeved on the rotating shaft, the top wheel is provided with a lower forming groove matching the exhaust straight pipe, the workbench is hinged with a rotating handle by a hinge, the rotating handle comprises a main power arm and a slave power arm, the workbench is also provided with a limit assembly for limiting the rotation range of the rotating handle, the slave power arm is connected to the lower pressure plate by a connecting rod, the lower pressure plate is provided with a pulley, and the pulley is provided with an upper forming groove matching the exhaust straight pipe; when using this device to bend the exhaust straight pipe, a tensioning spring is inserted into the exhaust straight pipe, and the exhaust spring will tighten the inside of the exhaust straight pipe during the downward pressure process to prevent the exhaust straight pipe from becoming flattened during bending. At the same time, the forming groove on the rolling wheel cooperates with the straight pipe to increase the force area and ensure that the force at the bending point is uniform to prevent cracks from occurring at the bending point.

[0004] Based on the above, in order to avoid changes in the diameter of the exhaust elbow when forming the exhaust elbow, a tension spring will be inserted into the pipe before processing to make the pipe evenly stressed, and the tension spring will be pulled out after the forming is completed. However, it takes a long time to remove and place the spring, which affects the processing efficiency of the exhaust pipe and further affects the use effect of the forming and finishing device.
