Problems solved by technology

However, the stainless steel materials available on the market are relatively hard. If the traditional flat wire is used to punch and then arrange the teeth in the tooth row machine to make stainless steel chain teeth, the loss of the mold will be large, the material utilization rate will be high, and the cost will be high; if the stainless steel powder is added with a binder Injection molding and sintering, the process is complicated, the relative density of the product is lower than the original density of stainless steel, and the advantages of stainless steel cannot be fully realized
So far, stainless steel tooth zippers are not competitive in the market and cannot be promoted.

Embodiment 1

[0022] Embodiment 1: a kind of preparation method of stainless steel tooth slide fastener, comprises the steps:

[0023] A. Design the drawing and rolling "Y" shaped wire die, and select the suitable drawing and rolling equipment;

[0024] B. Select 2.65mm in diameter and grade 202 stainless steel wire, and anneal and soften it to make the Brinell hardness ≤ 200;

[0025] C. Stainless steel wire rod 2 drawn and rolled into a "Y"-shaped section 1, such as figure 1 and figure 2 shown;

[0026] D. Arrange the teeth in the tooth row machine, and prepare the chain teeth 3 on the cloth belt 4 such as Figure 3-Figure 5 As shown, the stainless steel tooth zipper products are made by post-processing combination, such as Image 6 shown.

[0027] Wherein, in the stainless steel wire rod 2 of "Y" shape section 1, "U" shape part 11 is provided, and inside the port of "U" shape part 11, a pair of convex parts 12 are set; A pair of ribs 13 are provided in the inner groove of 11 .

...

Abstract

The invention relates to a stainless steel tooth zipper and a manufacture method thereof. The stainless steel teeth include pairs of bilaterally-symmetrical tooth bodies, concave surface portions and tooth point portions, wherein the concave surface portions and the tooth point portions are connected in a consubstantiality mode and arranged on the tooth bodies. The concave surface portion is matched with the tooth point portion on the other tooth body in a buckled mode, external clamping convex portions are arranged at the ports on the inner sides of the tooth bodies, and internal clamping convex portions are arranged in the middle of the inner sides of the tooth bodies. The manufacture method of the stainless steel tooth zipper is that a stainless steel wire processed by softening is pull-rolled into a stainless steel wire with a Y-shaped section, then arrangement of teeth is performed by a tooth arrangement machine, and post-processing combination is performed to obtain a stainless steel tooth zipper product. The product has the advantages of being high in corrosion resistance, large in tensile strength, good in quality, high in grade and the like. In addition, the cost of the product is reduced.

Description

technical field [0001] The invention relates to the technical field of slide fasteners, in particular to a stainless steel tooth slide fastener and a preparation method thereof. Background technique [0002] The zippers currently on the market are widely used with nylon tooth zippers, resin tooth zippers, copper tooth zippers, aluminum alloy tooth zippers, etc. These zippers have defects such as low tensile strength, easy wear, tooth burst, low lifespan, discoloration, and fading to varying degrees. Stainless steel has the characteristics of high tensile strength, corrosion resistance, permanent capital return, etc., and the product is of high grade. However, the stainless steel materials available on the market are relatively hard. If the traditional flat wire is used to punch and then arrange the teeth in the tooth row machine to make stainless steel chain teeth, the loss of the mold will be large, the material utilization rate will be high, and the cost will be high; if ...
