Description

A kind of slide fastener wire rod and slide fastener coupling element

Technical field

The present invention relates to a kind of slide fastener wire rod and slide fastener coupling element.

Background technology

In the manufacturing technology of metal zip fastener, all metal material is supplied with the metal zip fastener manufacturing equipment with the form of wire rod, so just can reach the stable production of high speed of metal zip fastener, and the end face of the metal wire rod of this production metal zip fastener normally rectangle and Y shape.

Because the zipper sprocket side face that the slide fastener wire rod of rectangle end face is made; The profile that is tooth is to shear through the punching press of the composite die of slide fastener machinery to form; Have a lot of straight lines, the arc angle line combines; Therefore such metal zip fastener tooth is then presented the punching press shearing vestige and a lot of straight lines of zipper teeth side face after clipping on the zipper strip; The vestige that the arc angle line is connected, thus make the roughness on two sides of zipper teeth poor, make the not attractive in appearance and zipper head of slide fastener drawing have some setbacks when opening sliding etc.

The metal zip fastener tooth that metal wire rod Y shape end face is made; Then be to be clamped on the strap of slide fastener metal Y shape wire rod is cut into the material that equates with metal zip fastener transverse tooth thickness degree by slide fastener machinery after; Because the bipod limit of the end face of this Y shape wire rod that is used to make the metal zip fastener tooth; The two sides of just processing the metal zip fastener tooth are to be made up of many angle lines, circular arc; Therefore by the slide fastener mechanical cutting and after clipping on the zipper cloth belt, the two sides of such metal zip fastener tooth also seem, and uneven outward appearance is not attractive in appearance yet, and zipper head draws and opens also inadequately along sliding.

Summary of the invention

The object of the invention is to provide a kind of slide fastener wire rod and the slide fastener coupling element processed of slide fastener wire rod thus, and the slide fastener surface that makes it process is smooth, and drawing of zipper head opened along sliding.

Above-mentioned slide fastener wire rod comprises head, and head is extended with a pair of shank, and opening between two shanks has an angle; The outer surface of said shank is a cambered surface toward interior bending; Make the section of slide fastener wire rod V-shaped, after two shanks pressed relatively, the outer surface of two shanks was a plane or cambered surface.

Because the outer surface after two shanks press is a plane or cambered surface, so the slide fastener surface that adopts this wire rod to process is smooth, can be not uneven, drawing of slider of zipper fastener opened become more suitable sliding.

Preferably, the section of said head is inverted trapezoidal.

Preferably, the end of said shank is extended with the leg pawl, and opening between leg pawl and shank has an angle.

Be provided with the leg pawl at shank, the leg pawl is used for the strap that slide fastener is made in fastening.

Preferably, the inboard transition face of said shank and leg pawl is provided with recess.

The inboard transition face of shank and leg pawl is provided with recess, makes things convenient for the leg pawl to press toward the recess place.

Preferably, the spacing of said head bottom surface to shank inner surface is 1.8-2.2 a times of head bottom surface to shank bottom spacing, and the spacing at head bottom surface to leg pawl top is 1.7-2.3 a times of head bottom surface to shank inner surface spacing.

Preferably, the curvature of said shank outer surface is 2.1-4.5.

And different, the preferred version of No. 3 slide fastener wire rod curvature is 2.1-3.1 to the curvature of cambered surface according to the slide fastener wire rod of different model, and the preferred version of No. 5 slide fastener wire rod curvature is 2.5-3.5, and the preferred version of No. 8 slide fastener wire rod curvature is 3.5-4.5

Preferably, open angle is the 56-66 degree between said two shanks.

Preferably, the width of said head bottom surface is 0.5-0.8 a times of two shank outer surface spacings, and the spacing of two shank inner surfaces is 0.4-0.6 a times of two shank outer surface spacings.

A kind of slide fastener coupling element that adopts above-mentioned slide fastener wire rod to process; Comprise head, head is extended with a pair of shank, and opening between two shanks has an angle; The outer surface of said shank is a cambered surface toward interior bending; Make the section of slide fastener wire rod V-shaped, after two shanks pressed relatively, the outer surface of two shanks was a plane or cambered surface.

Because the outer surface after two shanks press is a plane or cambered surface, thus the smooth surface of slide fastener coupling element, can be not uneven, drawing of slider of zipper fastener opened become more suitable sliding.

Preferably, it is inverted trapezoidal that the section of said head is, and the curvature of shank outer surface is 2.1-4.5.

Description of drawings

Fig. 1 is a stereogram of the present invention;

Fig. 2 is an end view of the present invention.

The specific embodiment

The embodiment of slide fastener wire rod of the present invention is as depicted in figs. 1 and 2, comprises head 1, and head 1 is an inverted prismatoid; The two sides 2 of head 1 are the plane, and the angle, two ends 9 of head 1 bottom surface 10 is a circular arc, and the angle, two ends of end face 7 is extended with shank 4; 4 of two shanks open has an angle a, and this angle a is 61 degree, and the outer surface 3 of shank 4 is single cambered surface; Cambered surface begins toward inside bend at shank 4 and head 1 connecting place, and different, the preferred version of No. 3 slide fastener wire rod curvature is 2.6 to the curvature of cambered surface according to the slide fastener wire rod of different model; The preferred version of No. 5 slide fastener wire rod curvature is that the preferred version of 3, No. 8 slide fastener wire rod curvature is 4, and promptly the radian of shank 4 outer surfaces 3 bendings is less; Make shank 4 outer surfaces 3 be similar to a plane, and the inner surface 5 of shank 4 is provided with bent angle 8 with head 1 end face 7 connecting places, and the curvature of the surfaces externally and internally of shank 4 is consistent with the face that links to each other of head 1 side 2; Two surperficial opposing parallel, thereby end face of the present invention is V-shaped.

The end of said shank 4 is extended with leg pawl 6; 4 of leg pawl 6 and shanks open has an angle; The end of leg pawl 6 is protruding triangle body 11, and after two shanks 4 were pressed, leg pawl 6 was used for the strap that slide fastener is made in fastening; The interior lateral surface of leg pawl 6 is parallel plane, and leg pawl 6 is provided with recess with shank 4 inboard transition faces.

As shown in Figure 2, the width of head 1 bottom surface 10 is b, and the spacing of two shanks, 4 inner surfaces 5 is B; The spacing of two shanks, 4 outer surfaces 3 is A, and b is 0.65 times of A, and B is 0.5 times of A; The spacing of head 1 bottom surface 10 to shank 4 bottoms is h in addition, and the spacing of head 1 bottom surface 10 to shank 4 inner surfaces 5 is H, and the spacing at head 1 bottom surface 10 to leg pawl 6 tops is C; And H is 2 times of h, and C is 2.05 times of H.

Because shank 4 outer surfaces 3 are similar to a plane with the face that links to each other of head 1 side 2; So after two shanks 4 are pressed relatively; The outer surface repoussage of shank 4 is a continuous plane or the less cambered surface of radian; Therefore the slide fastener surface that adopts this wire rod to process is smooth, can be not uneven, and drawing of slider of zipper fastener opened become more suitable sliding.

Slide fastener coupling element of the present invention is by above-mentioned slide fastener wire rod cutting gained, and the end face of shape and structure and slide fastener wire rod is consistent, and is specifically as shown in Figure 2.

The improved protection domain that also is regarded as patent on the basis of above embodiment.
