Description

Figaro, Milan chain manufacturing device and manufacturing method

The invention relates to a metal sheet used as an ornament for stamping, folding, and forming an inverted buckle with the precision of an inner button hole, and the Milan chain which is fastened end to end, in particular, a metal chain having two or more sections A chain manufacturing device that is different in shape, the same in the form of a chain link, or has the same shape of a chain link, and has a different style and pattern on the pitch surface, which integrates these links and makes them beautiful. method. Background technique

As is known to those skilled in the art, the so-called Milan chain jewelry refers to a series of Milan chains consisting of triangles, squares, double-sided squares, hexagons, circles and elongated links. In the prior art, only the generally linearly-shaped Milan chain forming technology is used, and the material is placed in an automatic forming apparatus, and the apparatus automatically completes the punching and combination of materials at one time. For example, the current production of a standard Milan chain can be roughly divided into two steps: the first step of "sheet forming", the original material is imported into the equipment for the production of Milan chain, the prior art design is mechanical and mold movement After the whole production process is completed, the original material enters the mold part of the equipment, and the punch in the mold pushes the shape of the hole of the fastening part on the original material under the pressure of the pressure head, and the feeder of the equipment pushes the sheet in steps. Push it to the position with the next step, and accurately punch the punch out of the formed sheet with precise step adjustment. The second step, "Forming the Milan Chain," forms a standard Milan 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 formed sheets of different pitches can only be made first, using manual assembly devices, assembly of pieces, standard Milan chain itself. The proportion of available materials is very small (20~30%). For example, the Ferro-style Milan chain must be assembled by hand. It is not only time-consuming and labor-intensive, the manufacturing efficiency of the chain is not high, and it is required to produce continuously throughout the day. In the chain, the workers must operate in shifts. Therefore, for the entire chain manufacturer, there are problems such as a large number of employed workers, high labor costs, and low chain capacity. In addition, the manufacture of the chain has the problem of low product quality, because the manufacture of the chain is mostly done by hand, because the manual process is difficult to control in a standard mode, and is susceptible to environmental, emotional and other factors. Affecting the concentration of workers' work, it is difficult to achieve standardization, resulting in problems such as poor quality stability and poor product quality of the chain products. In addition, most of the process flow of the chain does not set detection points, once the product has defective products. When it is often impossible to detect in time, the processing steps after the formation of the chain require the standard to be uncontrollable. 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 unstable, it will lead to significant economic losses to the chain manufacturer. Summary of the invention

In view of the problems existing in the prior art, the technical problem to be solved by the present invention is to provide an automatic chain manufacturing device and a manufacturing method thereof, and to achieve the standard requirements of the post-chain processing process, the entire production process is automated, and the manual is omitted. The instability of the job, the improvement of technology becomes operational and economic.

In order to achieve the above object, the method for manufacturing a Figaroro Milan chain according to the present invention comprises the following steps -

1. Firstly, by setting the working mode in the man-machine interface, using the design of the left pressure rocker arm and the right pressure rocker arm, the cam of the cylinder controlled by the programmable controller is used to push the cam to slide on the shaft for programmable control. The machine controls different pressure arm operations, and the left mold and the right pressure rocker apply pressure to the right mold through the left pressure rocker arm, and the left and right molds are respectively used to produce two different sizes of formed pieces, and each device can be Replacing molds of different sizes to produce shaped sheets of different shapes and sizes;

2. After step 1, different shapes of the left and right molds are used to produce different shaped forming pieces, and the signal of the programmable controller is used to control the left material conveying cylinder and the right material conveying cylinder to respectively convey the forming sheets to the formed chain. At the mold, when one set of molds is working, another set of molds is in standby state;

3. After step 2, when one of the molds starts working, the mold will buckle the formed material into the delivery position of the left feed arm and the right feed arm, and the signal is given by the programmable controller, and is transported by the left material. The cylinder and the right material conveying cylinder are transported to the outgoing mold of the material forming, and then the pressing device drives the forming web into the predetermined space of the chain mold through the signal of the programmable controller;

4. After step 3, when the forming piece normally enters the upper part of the predetermined outgoing mode, the signal control of the programmable controller adjusts the power cylinder to control the depth of the forming punch by using the fine adjustment screw of the pressing depth adjusting device, and is programmable. The signal control of the controller controls the forming cylinder to push the forming lever, and the forming punch is pressed into the outgoing chain mold by using the forming punch;

5. After step 4, after a set of molds has completed the preset work, the signal given by the programmable controller, the cylinder's dial pushes the cam to slide on the shaft, and switches to another set of pressure arm and mold. The feeding arm continues the same work as the above procedure.

To achieve the above object, the present invention is based on the Figaroro Milan chain manufacturing apparatus, which is realized by the following technical solutions: A Figaro Milan chain manufacturing device, comprising an organic seat, a programmable controller installed inside the base, a man-machine interface on the right side of the base, a left mold on the left upper part, and a left pressure on the left upper mold Rocker arm, the left mold side is provided with a left feeding arm, the left feeding arm is connected with the left material conveying cylinder, the right upper part of the machine base is provided with a right mold, the right mold is provided with a right pressing rocker arm, and the right mold side is provided with a right feeding arm, the right feeding material The arm is connected to the right material conveying cylinder, the upper part of the base is provided with a forming cylinder, the forming cylinder is connected with the forming lever, and the other end of the forming lever is connected with the forming punch.
