Music string ball head with the function of differentiating music strings and manufacturing process thereof

Abstract

The invention discloses a music string ball head with the function of differentiating music strings and a manufacturing process thereof. The music string ball head has an I-shaped wheel structure and is made of plastic mixture. The musical string ball head is made of plastics of various colors and has low cost, can be processed and molded conveniently, as well as has extremely good music string differentiating function. The invention also discloses the manufacturing process of the music string ball head, which comprises the following steps: (1) the molding step of the sectional material of the music string ball head: adopting an injection molding technology, taking the plastic mixture as the raw material and manufacturing the strip-shaped sectional material of the music string ball head; and (2) the processing and molding step of the music string ball head: turning and processing the obtained sectional material obtained from the step (1) and manufacturing the sectional material into the music string ball head.

Description

technical field [0001] The invention relates to a plastic string bead head with the function of distinguishing strings, and also relates to a preparation process of the string bead head. Background technique [0002] The bead head of the string is an indispensable object on the steel string. Its function is to be stuck on the bridge to fix one end of the string, and the other end is on the peg on the level. Because one end of the string is fixed on the bead head On the bridge, adjust the tension of the strings to achieve the sound required by the strings by rotating the aligned pegs. [0003] In the prior art, the string bead head is generally made of metal materials such as copper or iron, and the metal string bead head has the following defects: [0004] (1) Due to the high price of metal materials and the high cost of raw materials for string ball heads, string products lack market competitiveness. [0005] (2) The use of metal materials to make the string bead head req...

AI Technical Summary

Problems solved by technology

[0004] (1) Due to the high price of metal materials and the high cost of raw materials for string bead heads, string products lack market competitiveness

[0005] (2) The use of metal materials to make string bead heads requires cutting tools for turning processing. Since the metal material is hard, cutting tools with higher hardness are required to complete the turning processing. The requirements for processing equipment are high, and the processing cost is also high.

[0006] (3) Due to the hard metal material, the tool is easy to wear during turning, and even damages the tool in serious cases, so the tool needs to be replaced frequently, which will increase the cost of the tool on the one hand, and prolong the processing time on the other hand, which is time-consuming and labor-intensive

[0007] (4) The string beads are made of metal materials. The prepared string beads have a single color and do not have the function of distinguishing strings. If you want to make them have the function of string identification, you need to coat the metal string beads. Coated with a layer of colored lacquer or plated with a layer of colored plating, but whether it is the painted layer or the plated layer, it is easy to wear off, indicating that the effect of the strings cannot last
