Automatic drilling equipment for oblique noise-reducing hole assembly for tubular silencer assembly

Abstract

The invention relates to a machinery field and relates to automatic drilling equipment for an oblique noise-reducing hole assembly for a tubular silencer assembly. The equipment comprises a drilling device body including a rack, on which an exhaust pipe installing seat is arranged. The exhaust pipe installing seat is detachably connected with an exhaust pipe. A lower cutter wheel used for punching the exhaust pipe is arranged below the exhaust pipe installing seat. The outer wall of the lower cutter wheel is provided with at least five outer protrusions matched with hole shapes. The outer protrusions are annularly distributed on the outer wall of the lower cutter wheel at equal angles with the central axis of the lower cutter wheel as the central line. The lower cutter wheel is engaged with the exhaust pipe. The lower cutter wheel is connected with a hydraulic driving pump through a driving part. The automatic drilling equipment for the oblique noise-reducing hole assembly for the tubular silencer assembly has following beneficial effects: by optimizing a conventional manual drilling mode, drilling of the exhaust pipe is achieved during the process of engaging the lower cutter wheel with the exhaust pipe.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a punching device. Background technique [0002] Noise reduction devices are widely used in modern industry, especially after the introduction of a series of national energy-saving and noise reduction standards, enterprises began to pay attention to the development and operation of various energy-saving emission reduction, noise reduction and noise reduction projects. Noise reduction devices can effectively hinder sound transmission Letting air flow through and controlling noise is an essential tool for noise reduction in various industries and an indispensable equipment for environmental protection. According to different product uses and noise reduction design principles, it can be roughly divided into: fan silencer, steam silencer, exhaust Steam muffler, composite muffler, gas-liquid separation muffler, anti-jet resistance composite muffler, small hole muffler, blowpipe muffler, relea...

AI Technical Summary

Problems solved by technology

[0003] In the existing mufflers, there are sound-absorbing holes on the outer wall of the intake pipe. Traditionally, manual drilling is often used, which is not convenient for processing and consumes time and effort.
