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 after the 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

A kind of processing technology of improved high-grade string

Technical field

The present invention relates to a kind of processing technology that is used for the high-grade string on the shoegaze.

Background technology

String is the requisite member of shoegaze, and the quality of string is directly connected to plays effect.In the prior art, string mainly is made up of two parts: core 11 with twine crust 12, no matter be that high-grade string or low-grade string all are made up of these two parts, used material and processing technology that different is is different, as shown in Figure 1.

In traditional handicraft, the core 11 (steel wire) of string is not handled through straightening, and core 11 surfaces are slick and sly; Be wrapped in 11 last times of core when twining crust 12 (copper wire), the finished product string is crooked, and because core 11 smooth surfaces; Twine crust 12 and be wrapped in 11 last times of core and on steel wire 11, slide easily, so the string outward appearance distortion of producing by traditional handicraft influences attractive in appearance; The string of distortion that main is is when playing; Its vibration is not a direction vibration, but towards the direction of twist vibration, the tonequality that does not have straight string to play out when the sound tone color of playing out with the string of distortion becomes clear clean; And because distortion vibrations of strings polytropism, also can cause the phenomenon of the article of beating and produce noise.

In traditional handicraft, be wrapped in slick and sly 11 last times of core when twining crust 12, a period of time tone color that harsh output is come can be relatively good; But after playing a period of time; Since vibrations of strings be installed to the tension that produces on the qin, the winding crust 12 that wraps on the core 11 is easy to produce chronic slip, makes to twine the adhesive force that crust 12 is wrapped on the core 11 and descend; The tone color of string will change after use a period of time, and the tone color life-span of string is shortened.

In the prior art, the core 11 of high-grade string generally all is the hexagonal wire that adopts import, because it is relatively more straight after making the string finished product; And the relative slip that can effectively prevent to twine crust 12 (copper wire) and core 11, but also have defective, because the cross section of core 11 is hexangle types; Be wrapped in 11 last times of core when twining crust 12, twine crust 12 and can not touch core 11 completely, at the hex surface of core 11 with twine 12 of crusts and can exist the gap; As shown in Figure 2, the contact point that twines crust 12 and core 11 is six corners of core 11, acts on the adhesive force that twines on the crust 12 like this and concentrates on six corners of core 11; Because core 11 exists with the gap of twining crust 12; String in use, the winding crust 12 that is wrapped on the core 11 can slowly be pressed nearly clearance plane, and the adhesive force that acts on 11 6 corners of core is weakened; Thereby it is loosening easily to cause twining crust 12, influences the tone color life-span of string.

Summary of the invention

The object of the present invention is to provide a kind of processing technology of improved high-grade string, the high-grade string that adopts this processes to come out can keep the quality requirements of high-grade string more for a long time, prolongs its tone color life-span greatly.

The processing technology of a kind of improved high-grade string provided by the invention may further comprise the steps:

(1) straightening core: carry out straightening to the web-like core through the automatic linear engine of steel wire and handle; Its process is that core one end is clipped between the pair of traction wheel of the automatic linear engine of steel wire; When traction wheel rotated, the pulling core moved, the machine straightening device of the automatic linear engine of steel wire rotation simultaneously; See the core after the straightening off through traction wheel, after reaching preseting length, cut off;

(2) increase core skin-friction force: the core that will pass through the straightening processing carries out mantle friction to be handled, and the medium of friction core is made up of two grinding wheels, and two grinding wheels are through the motor shaft connection and by driven by motor; The two ends of core are stretching fixing; And be placed in two gaps between the grinding wheel revolving wheel sheet, simultaneously mobile motor and drive two grinding wheel core directions along the line and move; The grinding wheel friction core of rotation makes the roughness on core surface reach the setting requirement;

(3) twining crust twines and draws wicking surface: will twine crust and be wrapped on the core through the mantle friction processing and promptly get.

Core of the present invention adopts the special-purpose carbon structure steel wire of high-grade string core.

Winding crust of the present invention adopts copper wire, welding wire or alloy silk.

Gap between two grinding wheels of the present invention can be adjusted, and the gap is adjusted to and just run into core and be advisable.

The string of producing through processing technology of the present invention is at hanging state shape linearly basically; And the frictional force increase on core surface, after the winding crust was gone up in winding, twining crust was fully attached on the core; So twining the adhesive force of crust on core increases; String also is not easy to become flexible at the long-time back winding crust that uses, and has prolonged the tone color life-span of string, the permanent quality requirements that keeps high-grade string.

The specific embodiment

The high-grade string that the embodiment of the invention relates to mainly is made up of two parts: core 11 and winding crust 12, wherein core 11 adopts the special-purpose carbon structure steel wire of high-grade string core, twines crust 12 and adopts copper wire.

Because it is a volume volume that the Production for Steel Wire that string core 11 adopts is come out; Wall scroll steel wire after cutting is circular arc, and the string that such core 11 is produced twists, and must carry out straightening through the automatic linear engine of steel wire (commercially available) and handle the requirement that just can reach high-grade string single vibration; The straightening process of web-like core 11 is as shown in Figure 3; At first the machine straightening device 21 of web-like core 11 through the automatic linear engine of steel wire, core 11 1 ends are clipped between the pair of traction wheel 22 of the automatic linear engine of steel wire, when traction wheel 22 rotates; Pulling core 11 moves; Machine straightening device 21 rotations are simultaneously seen the core after the straightening 11 off through traction wheel 22, after reaching certain-length, cut off.Core 11 after the process straightening is near linear state, to reach high-grade core requirement with string.

Though the straight line degree of core 11 reaches, core 11 surfaces still are smooth, when copper wire 12 is wrapped in 11 last times of core; Copper wire 12 can slide on core 11; So also will carry out surface treatment,, copper wire 12 can not slided on core 11 to increase the frictional force on core 11 surfaces to core 11.

The technology that increases core 11 skin-friction forces is as shown in Figure 4, and the medium of friction core 11 is made up of two grinding wheels 32, and two grinding wheels 32 are through motor shaft 31 connections and by driven by motor; Gap between two grinding wheels 32 can be adjusted, and the gap is adjusted to and just run into core 11 and be advisable, and core 11 two ends are stretching fixing; And be placed in two spaces between the grinding wheel 32; Revolving wheel sheet 32, mobile motor and drive two grinding wheels, 32 core directions 11 along the line and move simultaneously, the grinding wheel 32 of the rotation cores 11 that rub; Make the roughness on core 11 surfaces reach the setting requirement; The core of handling like this 11 because the roughness on core 11 surfaces increases, can not slide copper wire 12 when twining copper wire 12 on core 11.

Adopt the string produced through the core 11 of above processing at hanging state shape linearly basically, and the frictional force on core 11 surfaces increase, after twining copper wire 12; Copper wire 12 is fully attached on the core 11; Like Fig. 5, shown in 6, so the adhesive force of copper wire 12 on core increases, string also is not easy to become flexible at the long-time back copper wire 12 that uses; Prolonged the tone color life-span of string, the permanent quality requirements that keeps high-grade string.
