Problems solved by technology

[0006] Aiming at the existing problem that the two ends of the double-toothed branches are subjected to uneven force during the assembly process, resulting in the bending phenomenon of the double-toothed branches during the force-bearing process, the present invention provides a new multi-bead watchband assembly tooling with a structure Simple, the overall force of the double tooth branch is uniform, so it is not easy to bend and deform

Embodiment 1

[0040] For example, the model is a five-bead watch strap, made of 316L stainless steel, the main accessories are left bead 310, right bead 320, middle bead I330, middle bead II340, double tooth branch 400, single section 35 pieces, body part 20 pieces, body part Composition of 15 capsules.

[0041] Such as Figure 1 to Figure 7 As shown, a new type of multi-bead watchband assembly tooling in this embodiment includes an upper mold 100 and a lower mold 200. The lower mold 200 is provided with six accommodation cavities 210 along the transverse central axis. The structural shape of the accommodation cavities 210 is similar to that of the beads (the left bead or the right bead) the structural shapes are matched, the accommodation cavity 210 is provided with twelve first circular grooves 220 along the longitudinal side, and each accommodation cavity 210 is assigned two first circular grooves 220, each first circular groove A double tooth branch 400 can be placed in the groove 220;...

Embodiment 2

[0048] The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the cross-sectional shape of the through groove 110 is rectangular. Therefore, in order to facilitate demoulding of the watch bead, the width of the through groove 110 is greater than the width of the accommodating cavity 210 .

Embodiment 3

[0050] This embodiment provides a novel multi-bead strap assembly method, including the following specific steps:

[0051] Step S101, first put the double-tooth stick 400 into the lubricating oil and soak for 2-5 minutes, the optimal soaking time is 3 minutes, the lubricating oil can completely soak the entire end of the double-tooth stick 400, which can reduce the assembly time. Resistance; the lubricating oil is cutting lubricating oil, such as JQ-1 precision cutting lubricating oil commonly used in the market, etc., but not limited to the lubricating oil listed above;

[0052] Step S102, put the left bead 310 / right bead 320 of the multi-bead watchband to be assembled in the accommodating cavity 210 of the corresponding lower mold 200 according to the distinction between the bottom and the surface, and place the double tooth branch 400 according to the first position of the lower mold 200. The round groove 220 is placed flat, then the upper mold 100 and the lower mold 200 ar...

Abstract

The invention discloses a novel multi-bead watch strap assembly tooling and an assembly method, belonging to the technical field of watch strap assembly. At least six accommodate cavities are arrangealong that transverse central axis of the lower mold, the structural shape of the accommodate cavities is matched with the structural shape of the surface bead, at least twelve first circular groovesare arranged along one longitudinal side of the accommodate cavities, and two first circular grooves are arranged for each accommodating cavity; The upper mold is provided with a through groove alongthe transverse central axis, and the through groove is provided with a second round groove along the longitudinal side which is the same as the first round groove in number, and the first round grooveand the second round groove are combined to form an entire round and double-tooth branch mounting channel. By arranging the upper mold and the lower mold, placing the edge beads in the accommodatingcavity, and then assembling the double tooth branches on the edge beads, the invention fully utilizes the function of the upper mold and the lower mold to ensure that the double tooth branches are uniformly stressed during the assembly, so that the double tooth branches are not easy to bend and deform, the problem of inflexible rotation of a single section of the watch strap is reduced, and the repairing rate is reduced to 2%.

Description

technical field [0001] The invention belongs to the technical field of strap assembly, and more specifically relates to a novel multi-bead strap assembly tool and an assembly method. Background technique [0002] Generally, the metal watchband with solid core loose beads will connect the watch beads in series with the steel needle "double teeth branch" with teeth at the head and tail to form a whole. The number of watch beads should be at least three or more. Press the branch into the left bead hole, put the middle bead into the middle of the pressed side bead and place it on the flat plate, align the teeth of the double-toothed branch with the two holes of the right bead, and then use the right hand on a round plane with a handle Press the teeth of the double-tooth branch into the hole of the right bead, and so on, connect multiple sets of beads at the same time to form a watch strap. Due to the lack of assembly machinery, general metal watch bands are made manually, which...
