230, cooperated with block tongue 230 so that upper mold 100 merges integral, upper mold 100 and the spelling of lower die 200 with lower die 200 by card slot 130
It connects completely, fit tolerance between the two is small, the required precision after assembling is effectively ensured.
In addition, the first circular groove 220 and the second circular groove 120 are half slot, the height of the first circular groove 220 or the second circular groove 120
The length L that H is greater than double tooth branches 400 is spent, it is specific to meet: H=L+ (0.08mm-0.1mm)；In addition, the first circular groove 220 and second
Circular groove 120 is merged into full circle, and whole diameter of a circle D is greater than the maximum outside diameter d of double tooth branches 400, specific to meet: D=d+
(0.02mm-0.03mm)。
In addition, the height H of the first circular groove 220 or the second circular groove 120 is greater than the length L of double tooth branches 400, it is specific to meet: H
=L+0.1mm；In addition, the first circular groove 220 and the second circular groove 120 are merged into full circle, whole diameter of a circle D is greater than double tooth branches 400
Maximum outside diameter d, it is specific to meet: D=d+0.02mm.
Same model can also be seven pearl watchbands, nine pearl watchbands, 11 pearl watchbands or even more, can use above-mentioned
Assembly tooling, be slightly improved on dimensional structure.
Embodiment 2
The structure of the present embodiment and the structure of embodiment 1 are substantially consistent, the difference is that: perforation groove 110 is cut
Face shape is rectangle, and after upper mold 100 and lower die 200 cooperate, accommodating chamber 210 and perforation groove 110 cooperate, therefore, for convenience
The width of the demoulding of table pearl, perforation groove 110 is greater than the width of accommodating chamber 210.
Embodiment 3
The assembly method for present embodiments providing a kind of novel more pearl watchbands, is included the steps that in detail below:
Step S101, double tooth branches 400 are put into lubricating oil first and are impregnated 2-5 minutes, optimal soaking time is 3 points
Clock, lubricating oil can soak the end of entire double tooth branches 400 completely, can reduce resistance when assembly；Lubricating oil is cutting profit
Lubricating oil, such as the common JQ-1 precision cutting lubricating oil of existing market etc., but do not limit to the above-mentioned lubricating oil enumerated；
Step S102,310/ the right pearl 320 of left side pearl of more pearl watchbands to be assembled is placed on phase according to the differentiation in bottom, face
Answer in the accommodating chamber 210 of lower die 200, and double tooth branches 400 according to lower die 200 the first circular groove 220 it is smooth put, then on
Mould 100 merges integral mould with lower die 200, whole mould is fixed on the plate of hand hydraulic cutting presser 500, it is ensured that whole mould and hand hydraulic cutting presser
500 pedestals are vertical, adjust the corresponding stroke of hand hydraulic cutting presser 500,500 phase of hand hydraulic cutting presser according to the height of the first circular groove 220 of lower die 200
End height+(10mm-15mm) of the bis- tooth branches 400 of the stroke S=H+ answered, then with the round handle of hand hydraulic cutting presser 500 from up to
Under impulse force double tooth branches 400 are pressed into the hole of 310/ the right pearl 320 of left side pearl.
Such as five pearl watchband of model, 6 left side pearls, 310/ the right pearl 320 can be put in lower die and enters double tooth branches simultaneously
400, five pearl watchband of the six roots of sensation can be assembled simultaneously, and assembly efficiency is high, can fill 400 edge beads per hour, and double tooth branches 400 exist
It can play the role of being easy into double tooth branches 400 after impregnating in cutting oil, the pore size control of edge bead is in ± 0.02mm range
It is interior, and enter the whole uniform force of double tooth branches 400, thus not flexible, deformation.
Schematically the utility model and embodiments thereof are described above, description is not limiting, attached drawing
Shown in be also one of the embodiments of the present invention, actual structure is not limited to this.So if this field
Those of ordinary skill enlightened by it, without deviating from the purpose of the present invention, not inventively design
Frame mode similar with the technical solution and embodiment, all should belong to the protection range of the utility model.
