Description
Technical Field
[0001] The utility model relates to the technical field of musical instrument processing equipment, specifically to processing equipment for violin bows, and particularly to a processing tool for bow rods. Background Art
[0002] At the 19th Conference of the Parties (CoP19) in November 2022, brazilwood was listed in the Convention on International Trade in Endangered Species of Wild Fauna and Flora for protection, which led to a significant reduction in the production of violin bows made of this material. In view of this, it has become inevitable to use other materials to replace brazilwood to make violin bows.
[0003] Research shows that the fiber orientation of bamboo is extremely consistent, superior to that of the vast majority of high-grade woods; the microfibril angle of bamboo is between 7° and 13°, while the microfibril angle of most woods is about 25° and varies greatly, so the longitudinal Young's modulus of bamboo is much better than that of wood; the density of bamboo is relatively small, about 0.7 - 0.9 g / cm³; the texture of bamboo is straight and it has good elasticity. After being properly bent and shaped, it is not easy to deform. By taking an appropriate bending direction, the bent shape can be maintained more durably. Therefore, a technical solution of using bamboo to make violin bows has been proposed.
[0004] However, when using bamboo to make violin bows, due to the influence of the thickness and material of bamboo, it is necessary to form the bow rod by splicing. The shapes of the spliced bow rods are diverse and need to be processed according to the standard shape of the violin bow. In the prior art, there is no tooling that can quickly and stably process the assembled bow rod into shape, which seriously affects the large-scale production of bamboo violin bows.
