A kind of automatic chain manufacturing device and manufacturing method

Abstract

The invention relates to an automatic chain manufacturing device and method. The material structure is changed from 2D to 3D, and a standard closing type riveted or welded mode can be achieved after combination. The device comprises a machine table, the machine table is provided with a material conveying device, the machine table is provided with a plurality of stations corresponding to corresponding function devices, the material conveying device is sequentially connected with a forging and pressing shear device, a vertical forging and pressing device, a horizontal forging and pressing device, a shear correction device, a rotating device, a claw disc closing device and a welding device. By means of a reasonable combination design mode, the structural strength is improved, and the weldingmode and manufacturing method are convenient.

Description

technical field [0001] The invention relates to an automatic chain forming method; it is mainly used to replace the current mainstream products generally manufactured by casting mode, including semi-finished chain link materials of wire and sheet materials, especially a method of rationally merging design mode, increasing Structural strength and convenient welding mode and manufacturing method. Background technique [0002] Those skilled in the art know that the so-called sheet chain jewelry refers to the uniform thickness, through stretching and horizontal correction of the sheet metal pattern notch pairing, according to different process requirements, the design appearance such as: follow the circle, rectangle, three-dimensional picture Shape, triangle, square, double-sided square, hexagon, circle, non-standard shaped. A series of sheet chains composed of different section lengths of the above shapes. In the prior art, the chains manufactured in the sheet mode are fasten...

Problems solved by technology

The other is based on the rigidity of the thickness of the material itself, which relatively increases the weight of the product, reduces the softness and comfort of wearing, and does not have a high cost performance relative to the price; if the precisely calculated 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 high speed and stably

At the same time, there are some uncorrectable problems with the traditional sheet chain

①. Because of the non-welding problem, it is very difficult to keep the shape of the product surface without deformation. Because of the non-welding reason, it is very difficult to deal with additional processes (such as batching, hammering, and smoothing processes), which cannot reach the general sheet jewelry. The surface treatment effect of the chain; ②, because the sheet material cannot change the thickness of the material in the general traditional equipment power, only the bending process can be performed, which limits the development of the structure and appearance of the product; ③, because there is no welding, It is impossible to keep the butt joints in a tight state, which will lead to the surface tension of the chain and produce gaps, and there will be hair pinching

Therefore, although this kind of chain has achieved noble, generous, bright, light weight and good viewing angle and economic effect in appearance, but because of the inevitable structural defects, it cannot expand its advantages of hollow core, generous and high-grade, so as to occupy a larger market share.
