Processing method of accordion sound spring

Abstract

The invention relates to a processing method of an accordion sound spring, which is characterized in that the processing method comprises the following steps that (1) a sound reed is punched for blanking; (2) a sound spring box and a rivet are assembled; and (3) the sound reed and the sound spring box are adjusted and riveted on a semiautomatic riveting device of the accordion sound spring. The processing method of the accordion sound spring has the advantages of scientific and reasonable design, simple process, easiness in operation, good sound quality, firmness in riveting, safety, reliability and higher innovation, and intonation is guaranteed.

Description

technical field [0001] The invention belongs to the field of accordion production, in particular to a processing method for accordion gongs. Background technique [0002] The accordion gong is the core part inside the accordion. The quality of an accordion depends on the overall production process of the gong. In China, the production process of accordion gongs is relatively backward. Taking the riveting process of gongs (riveting of gongs and gong frames) as an example, the specific steps are as follows: Drop out the required specifications of the sound reed, the head of the sound reed is a solid body; then, carry out preliminary riveting on the sound spring, and use the supporting plate to combine the sound reed formed by blanking and the sound spring frame on the mold Carry out the synchronous riveting (primary riveting) work of punching the reed hole and wearing the rivet; finally, adjust, rivet, and manually adjust the gap between the sound reed and the sound reed fram...

AI Technical Summary

Problems solved by technology

[0003] The following problems exist in the existing gong assembly method: 1. Due to the limitation of traditional equipment, the blanking of the phonic reed can only complete the processing on the shape of the phonic reed and cannot complete the processing of the rivet holes on the phonic reed. Traditional step-by-step The processing method makes the hole of the reed and the hole of the reed frame not on the same center line. This phenomenon will easily cause the gap between the reed and the frame of the gong to be uneven, which will affect the quality of pronunciation; 2. During the process of riveting the gong, the It is difficult to control the strength of the press. Excessive force will easily cause the spring frame to deform, making the pitch out of the tolerance range. Too small force will not ensure the firmness of the riveting, so that the stability of the quality of the gong cannot be guaranteed. In addition, the gong The riveting is to manually fix the gong to the lower end of the press, and a little carelessness will threaten the safety of personnel.
