Abstract
The invention discloses a wire stock for producing metal zipper teeth, the cross section of the wire stock presents an elliptical shape or a similar elliptical shape, the middle portion of two sides of the cross section forms arc-shaped embossments, when utilizing a drawing or a rolling technique to process the zipper teeth, the streamlined shape is favorable for easily shaping bidirectional tooth points, when shaping the tooth points of bidirectional teeth metal zipper in up-and-down symmetrical form, the wire stock is easier to be shaped with plump shape tooth points comparing with the wire stock with common rectangle cross section in normal use. Additionally, when the zipper teeth produced by utilizing the metal wire stock with elliptical shape cross section are assembled on a cloth belt, the part of the zipper teeth clinching the cloth belt presents a 'trapezoidal shape', thereby the zipper teeth has high strength, low cost, beautiful appearance and the like. Further, the metal zipper assembled with the 'trapezoidal shape' zipper teeth is smooth in zipping, low in zipping resistance and the like in zipping process.
Description
Technical field
The present invention relates to the slide fastener production field, especially a kind of wire rod of producing metal slide fastener tooth.
Background technique
As shown in Figure 1; copper or aluminium alloy flat horizontal line material that existing metal slide fastener tooth generally adopts the cross section to be rectangle; planting the tooth machining via metal, to make slide fastener monolateral; as; patrix machine and counterdie machine by continuous stepping mould; flat wire rod is carried out towards point, cuts triangle, crop formation tooth bud, at last tooth bud is clamped into zipper cloth belt and form the chain tooth.Adopt the flat wire rod machining chain tooth in this rectangular cross section, easy-formation and tooth point shape are not full inadequately during lower tooth point in the moulding.And adopt chain teeth structure that this wire rod makes shown in Fig. 2,3, its part of vising strap is rectangle, and not only than waste material, and resistance is bigger in the drawing process.
Summary of the invention
The purpose of this invention is to provide a kind of wire rod of producing metal slide fastener tooth, the tooth point easy-formation and the tooth point shape of chain tooth are fuller during its processing chaining tooth.
Technological scheme of the present invention is such: a kind of wire rod of producing metal slide fastener tooth, cross section two middle side parts of this wire rod are provided with arc convex.
The cross section of above-mentioned wire rod is ellipse or class ellipse.
After adopting such scheme, a kind of wire rod of producing metal slide fastener tooth of the present invention, its cross section ovalize or class ellipse, cross section two middle side parts form arc convex, when adopting drawing or binding technology machining chain tooth, the shape of streamline special easy-formation during to the two-way tooth point of moulding, when the tooth point of the two-way tooth metal slide fastener of upper and lower symmetrical molding, than in the wire rod moulding in the common rectangular cross section of normal use during lower tooth point this section bar more easy-formation and tooth point shape are full.And the chain tooth that adopts the planar metal wire rod of elliptical cross section of the present invention to produce, when being assemblied on the strap, its part of vising strap is " trapezoid shaped ", has that intensity height, cost are low, a beautiful shape etc.The metal zipper of this " trapezoid shaped " chain tooth is housed, and in the drawing process, drawing is smooth and easy, the drawing resistance is little etc.

The structural representation of the slide fastener that Fig. 6 dresses up for the chain tooth of using metal wire rod of the present invention and processing.
Embodiment
A kind of wire rod of producing metal slide fastener tooth of the present invention, as shown in Figure 4, wire rod 1 cross section ovalize, wire rod 1 cross section two middle side parts 11,12 form arc convex, when adopting drawing or binding technology machining chain tooth, the shape of streamline special easy-formation during to the two-way tooth point of moulding, when the tooth point of the two-way tooth metal slide fastener of upper and lower symmetrical molding, than in the wire rod moulding in the common rectangular cross section of normal use during lower tooth point this section bar more easy-formation and tooth point shape are full.
The chain tooth that adopts the planar metal wire rod of elliptical cross section of the present invention to produce, as shown in Figure 5, when being assemblied on the strap, its part 13 of vising strap is " trapezoid shaped ", has that intensity height, cost are low, a beautiful shape etc.As shown in Figure 6, the metal zipper of this " trapezoid shaped " chain tooth is housed, in the drawing process, drawing is smooth and easy, the drawing resistance is little etc.
Claims (2)
1, a kind of wire rod of producing metal slide fastener tooth is characterized in that: cross section two middle side parts of this wire rod are provided with arc convex.
2, a kind of wire rod of producing metal slide fastener tooth according to claim 1 is characterized in that: the cross section of above-mentioned wire rod is ellipse or class ellipse.
