A kind of welding method of sheet material chain structure

Technical field

The present invention relates to a kind of mouth of buckleing of jewelry sheet material chain diagonally designs and welding method, particularly one kind is with the most reasonable And close design pattern, increase structural strength and easily bond pattern and method.

Background technology

As it is known by the man skilled in the art that the jewelry of so-called sheet material chain refer to oblong rectangle stereotome shape triangle Shape, square, two-sided square, hexagon, circle etc. and the sheet material chain series lengthening chain link composition of above-mentioned shape.Existing Having in technology, the chain being manufactured with sheet material pattern, because not welding reason, all there are some important technical problems, such as With the rigidity of material itself, the weight having led to product increases fruit, decreases the comfortableness worn；If with accurate calculating Back-off angle mould formula although can with relatively thin material, but the required precision of equipment very high it is not easy to high-speed production.

Referring to shown in Fig. 1-1, the machining sketch chart of existing punching pin punch, approach processed by existing punching pin：Punching pin punch is circle Arc, processes (machining path 10) to the cutting of punching pin 21 punch along cutting path.Existing cutting is all to work along cutting path, because This can produce turning, and that is, incisory line footpath just creates R angle, arise that in the diagonal split of product plural number R angle and shape The circular space (position gap C) at angle.

And there are some no amendable problems in existing sheet material chain 310,1., because of solderless problem, product table Shape invariance shape is hard to keep (referring to Figure 11 in face very much：Arch upward place 312 on surface)；2., because unjointed reason, in additional process On processing mode extremely difficult it is impossible to reach the surface treatment effect of general wire rod ornamental chain；3., former because of solderless Because it is impossible to docking port is kept closely sealed situation, being directed at chain surface extensional and producing gap (referring to Figure 11：Docking port gap 313), have chuck find as.Although therefore such chain has reached noble, generous, beautiful, lightweight optimal in shape Visual angle and economic benefits, but because inevitable structure shortcoming is it is impossible to expanding the generous advantage improving grade of its hollow and occupying Bigger market share.For example, to design at present or make the chain of a plies formula it is necessary first to calculate the knot of its chain link Close intensity, then just can be carried out by the processor of current punching pin and die, it includes：Wire cutting machine, contain slow wire feeding The process equipment of wire cutting machine, middle wire wire cutting machine, fast wire edm cutter, chain saw etc., all cannot accomplish that binding site can Closed with hundred part hundred.Can see from above-mentioned mode, change after design and close, can be under manual or fully automatic mode produce Reach the realizability of chain structure, not only can optimize the structure of chain, original strength rigid is increased, by weight again Mitigate, the additional process processor of bigger difficulty can be carried out, thoroughly optimize whole leftover problems of piece ability chain series, order system Product are really achieved, noble, generous, improve grade, whole requirements of durable and high-purity value preserving, the following exploitation of product and market The very big occupation rate of extending space, the reason journey upright stone tablet of this exactly following jewelry development.
