Improved high-quality string processing technique

Abstract

The invention discloses an improved high-quality string processing technique, which comprises the following steps: (1) straightening a coiled wire core with a steel wire automatic straightening machine; (2) performing the surface rubbing treatment of the straightened wire core; and (3) winding a winding skin on the wire core subjected to the surface rubbing treatment. The string processed by the processing technique of the invention is basically straight in a vertically suspended state; the friction force on the surface of the wire core is increased, so when the wire core is wound with the winding skin, the winding skin is attached onto the wire core completely, the adhesive force of the winding skin on the wire core increases, and the winding skin is insusceptible to becoming loose afterthe string is used for a long time; and thus, the tone life of the string is prolonged, and the quality of the high-quality string is kept for a longer time.

Description

technical field [0001] The invention relates to a processing technology for high-grade strings on musical instruments. Background technique [0002] Strings are an essential component for playing a musical instrument, and the quality of the strings is directly related to the playing effect. In the prior art, the strings are mainly composed of two parts: the wire core 11 and the winding sheath 12, whether it is a high-grade string or a low-grade string, it is composed of these two parts, the difference is that the materials used and the processing technology are different. different, such as figure 1 shown. [0003] In the traditional process, the wire core 11 (steel wire) of the string has not been straightened, and the surface of the wire core 11 is smooth. When the winding sheath 12 (copper wire) is wound on the wire core 11, the finished string is curved. , and because the surface of the wire core 11 is smooth, the winding sheath 12 is easy to slide on the steel wire 1...

AI Technical Summary

Problems solved by technology

[0003] In the traditional process, the wire core 11 (steel wire) of the string has not been straightened, and the surface of the wire core 11 is smooth. When the winding sheath 12 (copper wire) is wound on the wire core 11, the finished string is curved. , and because the surface of the wire core 11 is smooth, the winding sheath 12 is easy to slide on the steel wire 11 when it is wound on the wire core 11, so the appearance of the strings produced by the traditional process is distorted, which affects the appearance, and the more important thing is that the twisted strings are playing When playing, its vibration does not vibrate in one direction, but vibrates in the direction of twisting. When playing with twisted strings, the sound quality is not as bright and clean as playing with straight strings, and due to the vibration of twisted strings Multi-directional, it will also cause the phenomenon of hitting the product and generate noise

[0004] In the traditional craft, when the winding sheath 12 is wound on the smooth core 11, the tone color will be better for a period of time when it is just produced, but after playing for a period of time, due to the vibration of the strings and the sound produced by being installed on the piano Under the effect of tension, the winding sheath 12 wrapped on the wire core 11 is prone to chronic sliding, which reduces the adhesion of the winding sheath 12 wound on the wire core 11. shorten

[0005] In the prior art, the wire core 11 of high-grade strings generally adopts imported hexagonal steel wire, because it is relatively straight after the finished string is manufactured, and can effectively prevent the relative tension between the sheath 12 (copper wire) and the wire core 11 from being wound. Sliding, but there are also defects. Since the cross section of the wire core 11 is hexagonal, when the winding sheath 12 is wound on the wire core 11, the winding sheath 12 cannot completely stick to the wire core 11. The hexagonal surface of the wire core 11 and the winding sheath 12 There will be gaps in between, such as figure 2 As shown, the contact points of the winding sheath 12 and the wire core 11 are the six corners of the wire core 11, so that the adhesion force acting on the winding sheath 12 is concentrated on the six corners of the wire core 11, because the wire core 11 and the winding There are gaps in the sheath 12. During the use of the strings, the sheath 12 wound on the core 11 will slowly press against the gap surface, weakening the adhesion force acting on the six corners of the core 11, thus causing the sheath 12 to wrap around the core 11. Easy to loosen, affecting the timbre life of the strings
