Welding method for sheet chain structure

Abstract

The invention discloses a welding method for a sheet chain structure. A sheet chain can achieve a closed type weldable mode. According to the welding method for the sheet chain structure, a punch male die is cut or ground in a diagonal manner by means of a linear cutting machine or a grinding machine; a punch is manufactured in a linear diagonal manner; the section of the punch male die is conical; the diagonal connection step of positioning includes the steps that Y direction linear cutting is performed, the punch returns to the linear machining end point position in the Y direction, and X direction linear cutting is performed; and the punch returns to the linear machining end point position in the Y direction, the punch male die is subjected to linear cutting or is ground in the X direction of a right angle, and after the punch male die is cut or ground, operation is performed according to the machining withdrawal path. According to the welding method for the sheet chain structure, under the condition that it is not required to increase the sheet thickness, the tension strength and the torsion strength are guaranteed; and the deformation of the shape of a chain in the wearing process is reduced, and sheet chain series products are comprehensively optimized.

Description

technical field [0001] The present invention relates to a buckle opening diagonal design and welding method of a jewelry sheet chain, especially a welding mode and method with the most reasonable combination design mode, increased structural strength and convenience. Background technique [0002] Those skilled in the art know that the jewelry of the so-called sheet chain refers to the sheet chain series composed of round, rectangular, three-dimensional pictures, triangles, squares, double-sided squares, hexagons, circles, etc. . In the prior art, chains manufactured in sheet mode have some important technical problems because there is no welding reason. If the rigidity of the material itself is used, the weight of the product will increase and the wearing comfort will be reduced. ; If the precise calculation of the undercut angle mode is used, although thinner materials can be used, the precision requirements of the equipment are very high, and it is not easy to produce at ...

Problems solved by technology

[0005] Therefore, we can see that by using the existing technology and equipment and changing the design mode, the popular products more than a hundred years ago can be fully optimized and transformed, and the changed products will not have the original structure and appearance defects. The problem is to keep all the advantages of the sheet chain, and to clarify the manufacturing thinking for the future product development direction. At the same time, because of the inability to weld, the chain cannot be made of a thinner (sheet material thickness) to make a lighter chain. It is impossible to carry out multi-style additional flower batching process on thinner chains. The old chains can only be stretched and cannot be twisted. At the same time, because of the closed mouth and no welding, the wrapping pieces are easy to deform and produce gaps, which will pinch hair and so on. Stability factors, so that the sales volume of the product cannot be increased, the rework rate is high, and the relative cost and interest of the manufacturer increase
