Problems solved by technology

However, these two methods are not suitable for the carbonization process of acoustic guitar soundboards, because guitar soundboards are often made of thin plates with a thickness of less than 5mm, and the same carbonization effect can be achieved on the surface and deep layers at a relatively low temperature. If it is heat treatment at a higher temperature, its mechanical properties such as bending and impact resistance will be greatly reduced, and it will not be able to meet the mechanical strength required by the string tension and other soundboards.

Embodiment 1

[0026] A heat treatment process of acoustic guitar soundboard includes the following steps:

[0027] S1: The choice of soundboard: Choose the Ingerman spruce from the coniferous wood commonly used in guitar panels, specifically the Ingerman spruce with no knots, no worm eyes, and no grain, choose the uniform wood texture, and each soundboard Wood whose growth ring width deviation does not exceed 1-2mm;

[0028] S2: Drying of the soundboard: drying the coniferous wood or hardwood at a temperature of 60°C to a moisture content of 10%;

[0029] S3: Processing of soundboard: Cut the coniferous wood or broad-leaved wood into a thin plate with a thickness of 4mm, a length of 500mm and a width of 500mm with a wire saw or a table saw, and then cut into a specified sample size, and The thin plates are stably stacked in the heat treatment equipment at an interval of 5m;

[0030] S4: Preheating and humidification of sound board: Preheat the thin plate from room temperature to 100°C at a heating...

Embodiment 2

[0041] A heat treatment process of acoustic guitar soundboard includes the following steps:

[0042] S1: Soundboard selection: choose the acacia wood commonly used in guitar panels. Specifically, choose the acacia wood with no knots, no insect eyes, no texture and bending, and the wood texture is uniform, and the width of the growth ring on each soundboard is deviated Wood not exceeding 1-2mm;

[0043] S2: Drying of the soundboard: drying the coniferous wood or hardwood at a temperature of 80°C to a moisture content of 9%;

[0044] S3: Processing of soundboard: Cut the coniferous wood or broad-leaved wood into a thin plate with a thickness of 4mm, a length of 500mm and a width of 500mm with a wire saw or a table saw, and then cut into a specified sample size, and The thin plates are stacked in the heat treatment equipment at an interval of 6m;

[0045] S4: Preheating and humidification of the sound board: The thin plate is preheated from room temperature to 100°C at a heating rate of...

Abstract

The invention discloses a heat treatment process of acoustic guitar sound boards comprising following steps: S1. sound board selecting; S2. sound board drying; S3. sound board processing; S4. sound board preheating and humidifying; S5. sound board heating and insulating; S6. sound board cooling; S7. sound board water content adjusting; S8. sound board polishing and splicing. High temperature heating processes are separately performed on the front part, side part and back part sound boards of a guitar before guitar processing and assembling; the guitar sound boards after high temperature heat treatment are not liable to absorb water or crack and the dimensional stability is greatly increased; the acoustic performance of the guitars with the sound boards that are subjected to the carbonization treatment is superior to other guitars which are not subjected to the carbonization treatment. The heat treatment process of acoustic guitar sound boards is a green and environmental protection processing method for novel instruments.

Description

Technical field [0001] The invention relates to the technical field of processing soundboards for musical instruments, and is a high-temperature heat treatment method specifically for acoustic guitar soundboards, and more specifically a heat treatment process for acoustic guitar soundboards. Background technique [0002] Acoustic guitar refers to a stringed instrument made of solid wood as the main material that can be played more clearly without plug-in assistance. It mainly includes folk guitars, classical guitars, flamenco guitars, etc., because of its beautiful sound and easy to play And other characteristics, deeply loved by the masses. [0003] The soundboard is the most important sounding component in the guitar. The guitar soundboard is generally divided into a front panel, a back panel and a side panel. Usually a good acoustic guitar uses some precious solid wood veneers as its face, back, and side panels, and these veneers are often caused by changes in air humidity, res...
