Description

Technical Field

[0001] The utility model relates to the technical field of automobile exhaust pipe welding, and more specifically to a welding forming tool for an automobile exhaust pipe with an irregular shape. Background Art

[0002] The automobile exhaust pipe is a pipe used to guide the exhaust gas left after the engine is working to the outside of the car. Since the engine will exhaust intermittently at a high frequency when working, the vibration and noise caused by the exhaust gas need to be purified in the exhaust pipe, and the exhaust gas itself also needs chemical treatment. The exhaust pipe of regular shape is formed by bending an iron plate during processing, and then the seams are welded to complete the processing of the exhaust pipe. Welding requires welding forming tooling;

[0003] The existing welding tooling is not convenient for closely fitting the edge of the exhaust pipe at the welding position, and the welding quality is easily affected due to the large weld.

[0004] The utility model of Chinese patent application number CN202121456576.0 discloses a welding forming tool for automobile exhaust pipe processing, including a tool body, wherein a base is fixedly provided at the lower end of the tool body, and a first driving motor is fixedly provided on both sides of the lower end of the base. A bidirectional threaded screw is provided on one side of the first driving motor for transmission. By placing the exhaust pipe to be processed with the weld facing upward inside the clamping plate, the first driving motor is started to drive the bidirectional threaded screw to rotate, and the bidirectional threaded screw nuts on both sides are driven to move toward the middle, and the clamping plate is driven to clamp the exhaust pipe to be processed, and the weld is pressed tightly. At the same time, the second changing gear at one end of the bidirectional threaded screw drives the first changing gear at one end of the unidirectional threaded screw, thereby driving the unidirectional threaded screw to rotate, and driving the unidirectional threaded screw nut to move downward, thereby driving the welding mechanism at one end of the first rotating support rod to rotate downward, so that the exhaust pipe corresponds to the laser welder up and down;
