Problems solved by technology

However, in the case of riveting and fixing such large-sized fastener elements and upper and lower stoppers to the fastener tape, since the amount of plastic deformation due to the riveting process is large, cracks and cracks are remarkably generated on the metal coating. , because the size of the cracks and cracks becomes larger, the problem of the appearance of the above-mentioned zipper components and the problem of corrosion are more serious

Embodiment 1

[0120] Hereinafter, specific examples are given to illustrate the present invention in more detail.

[0121] As Example 1, about manufacturing as a zipper component Figure 3 ~ Figure 5 The case of bottom stop 12 as shown will be described. The bottom stopper 12 of the first embodiment has a component main body made of pure copper and a metal plating film arranged on the surface of the component main body. In this case, the metal plating film is composed of an alloy of copper and zinc in which the copper content is 65 wt % and the zinc content is 35 wt %.

[0122] To manufacture the bottom stopper 12 of the first embodiment, first, a long pure copper wire having a circular cross section is cold-rolled so that the cross section of the pure copper wire is deformed into a substantially H-shape. Next, the component main body of the bottom stopper 12 is produced by cutting the pure copper wire having an H-shaped cross section to a desired thickness in its longitudinal direction. ...

Embodiment 2

[0132] As Example 2, the case where the metal fastener element 11 is manufactured as a slide fastener component is demonstrated.

[0133] The metal fastener element 11 of this Example 2 has the component main body part which consists of the alloy (brass) of copper and zinc, and the metal plating film arrange|positioned on the surface of the component main body part. In this case, the alloy constituting the component main body contains 85 wt% of copper and 15 wt% of zinc. In addition, the metal plating film is composed of an alloy of copper and tin having a copper content of 70 wt % and a tin content of 30 wt %.

[0134] In order to manufacture the metal fastener element 11 of the present Example 2, the engaging head etc. are formed by press-forming a brass plate material having a predetermined thickness, and the plate material is punched to produce the metal fastener element 11 parts of the main body. Thereafter, the obtained component main body was subjected to barrel grind...

Embodiment 3

[0138] As Example 3, the case where an outlet is manufactured as a slide fastener component is demonstrated.

[0139] The socket of the third embodiment has: a component main body using a zinc-based alloy as a metal base material; and a metal plating film arranged on the surface of the component main body. In this case, the component main body includes: a metal body made of a zinc-based alloy; and a copper base plating film formed on the surface of the metal body. In addition, the metal plating film is composed of an alloy of copper and zinc in which the copper content is 65 wt % and the zinc content is 35 wt %.

[0140] In order to manufacture the socket of the third embodiment, first, a metal body for the socket having a predetermined shape is formed by die-casting zinc. Next, the obtained metal body is subjected to electrolytic plating under predetermined conditions to form a copper base plating film on the surface of the metal body, thereby fabricating the component main ...

Abstract

A zipper component (1) comprising a component body (2) made of a metal and a metal plating film (3) provided on the surface of said component body. In this zipper component (1), at least a part of said component body (2) has been thermally treated before bending and thus said metal plating film (3) has a recrystallized structure wherein at least a part thereof has been recrystallized. Since the ductility of the metal plating film (3) can be improved thereby, when the zipper component (1) is bent, the metal plating film (3) can be deformed to follow the deformation of the component body (2). Therefore, the occurrence of crevicing or cracking in the metal plating film (3) can be prevented.

Description

technical field [0001] The present invention relates to a zipper component for a zipper to which at least a part of bending processing such as riveting is applied, and a manufacturing method thereof, and more specifically, to a zipper component having a metal component main body and a metal plating film arranged on the surface of the component main body. Zipper component, and its manufacturing method. Background technique [0002] Generally speaking, zippers use various zipper components such as zipper elements, top stoppers, bottom stoppers, inserts and sockets, and various zipper components such as sliders. parts. [0003] As one of such metal slide fastener components, there are fastener elements. Generally, metal fastener elements are formed by stamping a metal plate material such as copper or copper alloy having a predetermined thickness to form an engaging head and the like, and by punching the plate material, etc., to form a Roughly in the shape of a Y. Furthermor...
