Description

Technical Field

[0001] The utility model relates to the technical field of muffler processing, in particular to a hole-drawing processing device for an automobile muffler. Background Art

[0002] Automobile mufflers are a common component used in vehicles, helping to reduce noise pollution during driving. The principle is that the exhaust pipe consists of two tubes of different lengths, which are initially separated and then joined. The difference in length between the two tubes is equal to half the wavelength of the sound waves emitted by the car. When these two sound waves are superimposed, they interfere with each other, canceling out each other and reducing the sound intensity, thereby reducing the transmitted sound and achieving a noise reduction effect. The manufacturing process of automobile mufflers requires drilling holes.

[0003] According to Chinese patent publication number CN 218638321 U, a punching device for muffler processing is disclosed. Its technical solution includes: a punching table, wherein a cylinder is horizontally disposed in the middle of the upper surface of the punching table. The left end of the cylinder is fixed by a fixing seat, and the right end is supported by a support seat. The cylinder is provided with a row of evenly spaced through holes. A circular sleeve is mounted on the right side of the support seat. The circular sleeve is mounted on a round rod, which is fixed to the punching table. The upper surface of the punching table is provided with four columns mounted in a rectangular array. A top plate is mounted on the top of each of the four columns. Lifting rods are symmetrically mounted on the top of the top plate. The protruding ends of the two lifting rods extend through the top plate and are mounted with a punching plate. The four corners of the punching plate are slidably mounted to the four columns. A row of punching seats are evenly mounted in the middle of the bottom of the punching plate. Punching needles are fixed in the punching seats, and each punching needle corresponds to a through hole in the cylinder. This utility model achieves uniform punching of formed cylinders without deformation, thereby improving the processing quality of the cylinders.

[0004] However, when the device is fixing the muffler, the muffler may be damaged due to excessive downforce, affecting the processing effect. At the same time, it is inconvenient to clean the debris and dust generated during the muffler process. The practicality of the device is not high. For this reason, we propose a hole-drawing processing device for automobile mufflers. Utility Model Content
