Description

Musical instrument bullet dials first piece processingequipment Technical Field The invention belongs to the technical field of musical instruments, and particularly relates to a musical instrument plucking nail plate processing device. Background Traditional national plucked musical instruments in China such as zither, guqin, lute, three strings and the like are long in source and have a history of thousands of years. When playing such musical instruments, the playing nail plate is often used for playing strings, the playing nail plate is fixed on fingers for playing, the strings can be prevented from damaging the fingers of a player, the fingernails of the player can be easily caused to have problems due to insufficient thickness or improper trimming and the like, and the playing effect is easy to cause, and the played sound is more pleasant. The elastic nail plate is usually in a flake shape, generally adopts a thin copper sheet, an aluminum sheet, a thin ox horn sheet and the like, and with the advancement of material technology, chemical synthetic materials such as celluloid, terylene, nylon and the like are also often used at present, and carbon fiber composite materials can also be adopted. In the prior art, the edge shape of the plucking nail piece directly determines the playing effect and the use safety, which are closely related to the playing environment and the technical requirements of the musical instrument. In a playing scene, the edge of the plucking nail piece needs to be frequently contacted with the strings, and the edge of the nail piece is required to have accurate radian, uniform thickness and smooth surface. The string is easily damaged by over-sharp edge of the plucking nail piece, noise is generated, uneven resistance of the strings is caused by rough edge, stability of the intonation is affected, and the angle of plucking strings is limited by edge radian deviation, so that the skill of players is restricted. In the prior art, the nail-flicking sheet is often manually polished, the nail-flicking sheet is processed by referring to the edge shape of a processed nail mold, and the nail-flicking sheet is required to be continuously compared with the processed nail mold in the polishing process. Therefore, in the manual processing process, processing errors are easily generated between the elastic and poking nail pieces and the processing nail dies, the outer contour of the elastic and poking nail pieces cannot be kept consistent with the outer contour of the processing nail dies, and the processing accuracy of the elastic and poking nail pieces is affected. Disclosure of Invention The invention aims to provide a musical instrument plucking piece processing device, which aims to solve the problems that the accuracy of plucking piece processing is poor, the processing efficiency is low and the manufacturing and the use of the plucking piece are affected.
