Description

Technical Field

[0001] The utility model relates to a punching device, in particular to a microphone punching device with an automatic shedding function. Background Art

[0002] A microphone is an energy conversion device that converts sound signals into electrical signals. It is a device that is exactly the opposite of a speaker, and is the two terminals of a sound device. The microphone is the input and the speaker is the output. Microphones mainly include condenser microphones, crystal microphones, carbon microphones, etc. In addition, microphones are also called microphones, microphones, microphone tubes, etc. The microphone consists of a dustproof net, a shell, a diaphragm, a gasket, a back plate, and a copper ring. When producing the shell, the metal sheet needs to be stamped to stamp the metal sheet into the shape of the shell.

[0003] The existing metal sheet is stamped using a stamping machine, and the stamping steps are as follows: first prepare a metal sheet of appropriate specifications, then make a corresponding stamping die according to the design requirements of the microphone shell, install the stamping die on the stamping machine, and then place the prepared metal sheet on the stamping machine. After the upper and lower molds are closed, the metal sheet is deformed according to the shape of the mold through the pressure of the stamping machine, thereby forming the basic shape of the microphone shell. The above is the stamping process of the metal sheet, but there are still some shortcomings in actual use. For example, after the upper and lower molds are closed to stamp the metal sheet into a shell, when the upper and lower molds are separated, the shell will be affected by the stamping force and remain on the upper mold, so it is necessary to manually remove the shell from the upper mold, which increases the workload of the staff and reduces the stamping efficiency of the metal sheet.

[0004] Therefore, a microphone punching device with an automatic shedding function is particularly needed to solve the problems existing in the prior art. Utility Model Content
