Musical instrument, musical instrument assembly preparation

Abstract

This invention provides a preparation method for a musical instrument and its components including the following steps: 1, selecting mixing at least a kind of metal powder and a bonder to refine them to particles and the bonder is 7-61% in the volume percentage, 2, molding said particle state subject to molding to a blank, 3, removing the bonder in the blank, 4, sintering it and the blank is shrunk to a pre-molding one, 5, forging the molding object totally or partly to the final size and density.

Description

technical field [0001] The invention belongs to a method for preparing musical instruments and musical instrument components, in particular to a method for preparing integrally formed metal or alloy musical instruments and musical instrument components. Background technique [0002] Components of traditional wind instruments, such as figure 1 As shown, it is a perspective view of one of the keycaps in the wind instrument, figure 2 As shown, it is an exploded view of the key cover composed of two components (note: some key covers have more components). The key cover is made of figure 2 Two or more separate components are welded together figure 1 The key cover is finished, while the individual components are made by forging or lost-wax casting. [0003] The manufacturing process of the aforementioned existing wind instrument components has the following deficiencies: [0004] 1. The aesthetics of the welding place is insufficient, and manpower must be used for secondary...

AI Technical Summary

Problems solved by technology

[0004] 1. The aesthetics of the welding place is insufficient, and manpower must be used for secondary processing modification

[0005] 2. Due to the annealing problem after high temperature welding, the strength of the weld is poor

[0006] 3. Silver, cadmium, and zinc alloy welding consumables must be used for welding, and the heavy metals in them will cause serious pollution to the environment

[0007] 4. Due to the difference in density between the welding consumables used in welding and the material of the instrument itself, the uniformity of the entire instrument material itself after the finished product is poor, which affects the resonance and transmission of sound waves, so what appears is the sound quality and resonance of the instrument. Poor performance, can not achieve the expected effect

[0008] 5. The sound quality displayed by each material is not the same, and the sources of the aforementioned existing musical instrument materials are mainly profiles, so the selectivity is low and cannot meet the needs, for example, it is impossible to find the most suitable material according to the characteristics of resonance and transmission. s material

[0009] 6. The manufacturing process of the aforementioned musical instruments, due to many working hours and slow production speed, the cost is relatively high
