Description

Technical Field

[0001] The utility model relates to the technical field of power amplifier shell processing, in particular to a punching device for power amplifier shell processing. Background Technique

[0002] A power amplifier refers to an amplifier that can produce the maximum power output to drive a certain load (such as a speaker) under the condition of a given distortion rate. The power amplifier plays a "centralizing and coordinating" hub role in the entire audio system and, to a certain extent, determines whether the entire system can provide good sound quality output. During the production process of the power amplifier, a punching device is required to punch holes in the shell of the power amplifier. In the prior art, it is not convenient to fix and punch the shells of two groups of power amplifiers at the same time, which reduces the output per unit time. Moreover, it is not convenient to clean the power amplifier shells after punching and separately collect the generated debris and waste water, which may cause residue of impurities and affect subsequent assembly and use, and increase the difficulty of treating waste and waste water. Therefore, we propose a punching device for power amplifier shell processing to solve this problem. Content of the Utility Model
