Description

Figaro Milan chain manufacturing device and manufacturing method

technical field

The invention relates to a Milanese chain which is used as an ornament by punching and folding a metal sheet, and using the precision of the inner button hole to form an inverted buckle to fasten the head and the tail, especially a metal chain composed of two or more than two kinds of joints. Figaro Milan chains with different distances, the same form of chain links or the same external dimensions of the chain links, different styles and patterns on the pitch surface, a chain manufacturing device that integrates these chain links and makes them beautiful, and its manufacture method.

Background technique

Those skilled in the art know that the jewelry of the so-called Milan chain refers to the Milan chain series composed of triangles, squares, double-sided squares, hexagons, circles and extended links. In the existing technology, there is only the Milan chain forming technology with a uniform pitch. The material is placed in the automatic forming equipment, and the equipment will automatically complete the punching and combination of the material at one time. For example, the current production of a standard Milan chain can be roughly divided into two steps: the first step is "sheet forming", and the original material is input into the equipment for producing Milan chain. After completing the whole production process, the original material enters the mold part of the equipment, and the punch in the mold is driven by the pressure head to hollow out the hole shape of the fastening part on the original material, and at the same time, the feeder of the equipment pushes the sheet in steps. Push it to the position that matches the next step, and through precise step adjustment, the punch can accurately punch out the formed sheet. In the second step of "forming Milanese chain", the formed sheet forms a standard Milanese chain through the final reciprocating mechanical assembly action.

If the current process is to produce the Figaro Milan chain, in the known chain manufacturing process, the shaped sheets with different pitches can only be prepared first, and the manual assembly device is used to assemble piece by piece, and the standard Milan chain itself The proportion of available materials is very small (20-30%). For example, the production of Figaro-style Milanese chains must be assembled by hand. When producing chains, workers must operate in shifts. Therefore, for the entire chain manufacturing plant, there are problems such as too many workers employed, high labor costs, and low chain production capacity. In addition, the manufacturing of this chain has the problem of low product quality rate, because most of the manufacturing of this chain is done by hand, because the manual process is difficult to control in a standard mode, and it is easily affected by environmental, emotional and other factors. It affects the concentration of workers, and it is difficult to achieve standardization, which leads to problems such as poor product quality stability and poor product quality in the completed chain; in addition, most of the chain's manufacturing processes have not set up inspection points, once the product has a problem with defective products When the chain is formed, it is often impossible to detect it in time, and the standard of the processing procedure after the chain is formed cannot be controlled, because most of the products are made of precious metals, such as platinum, gold, K gold, palladium, precious synthetic metals, etc. If the quality is not good If it is stable, it may lead to major economic losses in the chain factory.
