Problems solved by technology

Imported hematoxylin used in bow sticks is not only an ideal material for making bow sticks, but also used in making expensive furniture and medicine. The demand for this kind of wood is very high, but the slow production of this kind of wood makes its value remain high, resulting in stringed instrument bow sticks The cost is very high; and because the size and specifications of the wood itself are different, the density of the grain is different, which makes the quality of the product difficult to be consistent and the effect of use is not the same

Embodiment 1

[0028] Embodiment 1. The violin bow of the present invention comprises a hollow carbon fiber bow and a wood layer wrapped outside the bow, and the hollow carbon fiber bow is filled with epoxy resin mixture. The method for making a violin bow comprises the following steps: cutting materials, cutting carbon fiber fabrics of a certain specification according to the needs of the violin bow made, as shown in Figure 1; making mandrels, processing plastic mandrels according to the wooden shape of the bow shape and specifications; forming, the cut carbon fiber cloth is rolled on the processed plastic mandrel, and the surface of the carbon fiber bow is wrapped with a wooden layer, and the wooden layer is made of wood into a sheet with a thickness of 2mm. The sheet-like wood layer is wound around the bow shaft at 360 degrees and fixed by adhesion. See Figure 2; Molding, put the rolled carbon fiber rod together with the mandrel into the mold, see Figure 3, then cover the upper mold, and ...

Embodiment 2

[0029] Embodiment 2 The cello bow of the present invention includes a hollow carbon fiber bow and a wooden layer wrapped around the bow, and the hollow carbon fiber bow is filled with epoxy resin mixture. The manufacturing method of the cello bow includes the following steps: cutting materials, cutting carbon fiber cloth according to the requirements for making the cello bow. Make the plastic mandrel, process it into the shape and specification of the corresponding plastic mandrel according to the shape and specification of the bow rod; form it, roll the cut carbon fiber cloth on the formed plastic mandrel by hand, and roll it on the carbon fiber bow The surface of the rod is wrapped with a wooden layer, and the wooden layer is made of wood into a sheet with a thickness of 2.5mm. The sheet-shaped wooden layer is wound around the bow rod at 360 degrees, and glued and fixed, so that the cello bow is completed. Molding, put the rolled carbon fiber rod together with the mandrel in...

Abstract

The invention discloses a stick of stringed musical instrument and making method, which is made of wood and carbon fiber, wherein the hollow carbon fiber stick is filled with composite material of epoxy resin. The making method comprises the following steps: tailoring the materials; making mandrel; shaping; winding wood layer on the surface; moulding; toasting; solidifying; cooling; stripping; extracting the mandrel; canning the core. The invention simplifies the manufacturing technique with high efficiency, which keeps wood sense of traditional stick with stable stick property and reliable quality.

Description

Technical field: [0001] The invention relates to a stringed instrument bow, in particular to a stringed instrument bow made of wood and carbon fiber and a manufacturing method thereof. Background technique: [0002] The pronunciation of stringed instruments is to rely on mechanical force to make the tensioned strings vibrate and pronounce. From the perspective of their pronunciation, stringed instruments are mainly divided into bowed stringed instruments and plucked stringed instruments. Bowed stringed instruments include violin, viola, cello , Double Bass, Electric Bass and Erhu etc. Among them, the bow stick in the bowed stringed instrument has a decisive influence on the performance performance. In addition to the dexterity of use, each bow stick has its own timbre. There are strict requirements on the length, weight, balance point, curvature, bending strength and elasticity of bow sticks. Due to the strict requirements on performance, there are very few types of wood th...
