Manufacturing process of mud whistle sound chamber

Abstract

The invention discloses the manufacturing process of a mud whistle sound chamber. The process comprises steps that S1, 3D modeling of the mud whistle sound chamber is completed based on 3DMax, lengthof a front section of an air hole is 22mm, length and width of the air hole are both 5mm, length of a rear section of the air hole is 12mm, wall thickness of the air hole is 1mm, and the angle betweenthe front section and the rear section is 135 DEG; S2, the model is inputted into Maya software and is divided into layer-by-layer cross sections, a printer is driven for printing layer by layer, andthe printing order is from an inner pipe wall of the sound chamber to the sounding portion of the sound chamber to a tail end mouth of the sound chamber to a whistle mouth of the sound chamber to anouter pipe wall of the sound chamber; S3, after printing is completed, the inner wall and the outer wall are polished, and the auxiliary support structure and rough selvedge are removed till the soundchamber normally sounds. The process is advantaged in that the sound chamber is manufactured based on the 3D printing technology, in the later stage, various types of handmade clay products can be directly embedded, the complicated process of making the sound chamber is made to be simple and convenient, and the mud products are made to be more popular and commercial.

Description

technical field [0001] The invention relates to the field of mud whistle production, in particular to a manufacturing process of a mud whistle cavity. Background technique [0002] The mud whistle is an intangible cultural heritage in Shaanxi Province. The sound cavity of the traditional mud whistle consists of a rectangular wooden stick (5cm×0.5cm×0.6cm), a square wooden stick (4cm×0.5cm×0.6cm) and a It is made by inserting a rectangular wooden stick (6×0.5cm×0.6cm). To make a qualified sound cavity, it needs to go through five steps of pre-insertion, demoulding, shape adjustment, shade drying, and baking, so that the sound cavity can pronounce normally, and the production process is complicated. The traditional handmade sound cavity has poor pressure resistance, and a slight bump will cause damage to the sound cavity. The production speed is slow, the time-consuming is long, the production efficiency is low, and the manual production cost is high, which cannot meet the m...
