Description

Technical Field

[0001] The utility model specifically relates to the technical field of muffler punching, in particular to a punching device based on motorcycle muffler processing. Background Art

[0002] The muffler is an important component of a motorcycle. The motorcycle engine produces a lot of noise when working. The muffler can reduce exhaust noise in various ways, making the motorcycle quieter when running and reducing interference with the surrounding environment and residents; it can adjust and control the exhaust airflow to make the exhaust smoother, thereby improving the engine's performance and fuel efficiency.

[0003] When the expansion tube inside the traditional muffler is being processed, the through holes on the expansion tube need to be punched by a punching device. However, when the traditional punching device is performing the punching process, it is necessary to effectively rotate the expansion tube of the muffler, and it needs to be rotated manually. In this way, during the punching process, the distance between two adjacent through holes may be inconsistent, which may cause unsatisfactory noise reduction effect when the exhaust gas is silenced.

[0004] A search revealed that Chinese patent publication number CN202121909847.3 discloses a device for punching holes in a plate for a silencer internal component. The device comprises a workbench with a punching mechanism fixedly connected to the upper surface of the workbench, and a stamping mechanism disposed above the punching mechanism. The punching mechanism comprises an upper pad, a fixing block fixedly connected to the lower side of the upper pad, an oil storage tank fixedly connected to the upper surface of the fixing block, an oil injection channel formed on the inner side of the fixing block, a sponge strip fixed to the inner wall of the oil injection channel, and the oil injection channel is connected to the oil storage tank via an oil guide pipe. The bottom surface of the fixing block is provided with a plurality of gasket mounting holes, and the top ends of the gasket mounting holes are connected to a first mounting hole.

[0005] When the device in the above patent punches the silencer, the upper module and the lower module are in contact, and then the punching pin is used to effectively punch the silencer. When the upper module and the lower module are in contact, the silencer may be deformed, which cannot effectively guarantee the shape of the silencer and may cause inconvenience in installation. In addition, the structure in the above patent cannot realize the rotation of the silencer and needs to be rotated manually. When adjusted manually, the two adjacent punching holes may be offset, which cannot effectively guarantee the silencer effect, and the work efficiency is low when adjusted manually.
