Abstract
A kind of metal wire rod being exclusively used in processing drawing chain tooth, a pair leg that there is a head and extended from described head by a cross part, described head, cross part and leg form a Y-shaped section jointly, one end of described head is provided with described cross part, the other end is provided with a field of conjugate action, and this field of conjugate action offers groove.The utility model structure is simple, practical, by arranging groove on the described field of conjugate action, this groove can adjust according to different model chain tooth curve of occlusion (adjustment groove shapes, size, the depth), be conducive to solving the problem that drawing process medium chain tooth joining frequently rubs, promote the stability of the light slippery of drawing.In addition, in actual production process, process two-way can the metal zip fastener product of drawing time convenient formation, and relevant to its production chip accessory can be able to first mate service life promotes.
Description
Technical field
The utility model relates to a kind of slide fastener wire rod, refers in particular to a kind of metal wire rod being exclusively used in processing drawing chain tooth.
Background technology
At present, Y wire rod method has become the most frequently used manufacture method of manufacture metal tooth, when Y wire rod legal system makes metal tooth, supply the wire rod of circular section off and on predetermined space for the manufacture of the metal wire rod of the circular section of chain tooth, produce the basic wire rod for Y shape section with the multistage rolling of multiple roll again, then the metal wire rod of Y shape section is cut into multiple chain tooth by predetermined thickness.The chain tooth of a cutting comprises a tooth head and a pair tooth pin, and two tooth pin are symmetrical and extend to form tooth head at interface point place, and two tooth pin and tooth head are Y shape, and a pair tooth pin formed opens.After chain tooth bud part presses installing space feeding strap, the marginal portion of strap is made to face between chain tooth bud part two tooth pin, now squeeze two in tooth die holder and squeeze cutter action in opposite directions, inwardly being extruded by two tooth pin makes tooth pin inwardly merge convergence, chain dental inlay is closed and is fixed on strap, is fixed on strap by chain tooth thus by pitch.
Chinese invention patent (the application number: 03110558.0 that YKK Co., Ltd of Japan applies at it, patent name: the metal wire rod making slide fastener coupling element and the slide fastener coupling element made thereof) disclose a kind of common metal wire rod structure, with an improved the stability of position of the metal tooth obtained by cutting Y wire rod, the intensity of chain tooth and chain tooth to the stability of the installation site of zipper strip.But, in the use procedure of reality, adopt above wire rod structure be processed into two-way can the metal zip fastener of drawing time, the light slippery of the drawing bad control in process of production of metal zip fastener, and the process tool accessory of correspondence is fragile.
Utility model content
The utility model provides a kind of metal wire rod being exclusively used in processing drawing chain tooth, and its main purpose is to overcome the defect that the metal zip fastener adopting the processing of existing metal wire rod to obtain has the bad control of the light slippery of drawing.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of metal wire rod being exclusively used in processing drawing chain tooth, a pair leg that there is a head and extended from described head by a cross part, described head, cross part and leg form a Y-shaped section jointly, one end of described head is provided with described cross part, the other end is provided with a field of conjugate action, and this field of conjugate action offers groove.
Further, described groove is deep-slotted chip breaker.
Further, the section of described deep-slotted chip breaker is that minor arc shape is arranged.
Further, the medial surface of each leg is furnished with at least one occlusion projection.
Compared to the prior art, the beneficial effect that the utility model produces is:
1, the utility model structure is simple, practical, by arranging groove on the described field of conjugate action, this groove can adjust according to different model chain tooth curve of occlusion (adjustment groove shapes, size, the depth), be conducive to solving the problem that drawing process medium chain tooth joining frequently rubs, promote the stability of the light slippery of drawing.In addition, in actual production process, process two-way can the metal zip fastener product of drawing time convenient formation, and relevant to its production chip accessory can be able to first mate service life promotes.
2, in the utility model, by arranging described groove, thus making on its engagement progress curve, to mold a little groove by its shaping chain tooth, being conducive to superfluous friction point to be avoided like this, thus reducing or eliminating engaging friction, promoting further and draw sense.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation that Fig. 1 observes on A direction.
Detailed description of the invention
Detailed description of the invention of the present utility model is described with reference to the accompanying drawings.
See figures.1.and.2.A kind of metal wire rod being exclusively used in processing drawing chain tooth, a pair leg 2 that there is a head 1 and extended from described head 1 by a cross part, described head 1, cross part 3 and leg 2 form a Y-shaped section jointly, one end of described head 1 is provided with described cross part 3, the other end is provided with a field of conjugate action 4, and this field of conjugate action 4 offers groove 5.Described groove 5 is deep-slotted chip breaker.The section of described deep-slotted chip breaker is that minor arc shape is arranged.The medial surface of each leg 2 is furnished with at least one occlusion projection 6.
See figures.1.and.2.The utility model by arranging groove 5 on the described field of conjugate action 4, this groove 5 can adjust according to different model chain tooth curve of occlusion (adjustment groove 5 shape, size, the depth), be conducive to solving the problem that drawing process medium chain tooth joining frequently rubs, promote the stability of the light slippery of drawing.In addition, in actual production process, process two-way can the metal zip fastener product of drawing time convenient formation, and relevant to its production chip accessory can be able to first mate service life promotes.
In addition, in the utility model, by described groove 5 is set to deep-slotted chip breaker, thus make on its engagement progress curve, to mold a little deep-slotted chip breaker by its shaping chain tooth, be conducive to superfluous friction point to be avoided like this, thus reduce or eliminate engaging friction, promote further and draw sense.
Above are only detailed description of the invention of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
