How to judge whether a stamping part needs to use a multi-station progressive die?

How to judge whether a stamping part needs to use a multi-station progressive die? Recently, many small partners have asked this question. Today we will briefly introduce the relevant content.

First of all, we need to master the question "What is a multi-station progressive die?" In fact, it belongs to one of the cold stamping dies. In a pair of molds, according to the stamping process to be processed, it is divided into several stations with the same distance. Each station should have a certain stamping process so that part of the stamping work of the part can be completed.

The material to be processed can be controlled by the automatic feeding mechanism, and the feeding distance can be controlled quite accurately. After punching at each station, stamping parts can be obtained. Generally speaking, it can continuously complete multiple processes such as punching, bending and deep drawing. It is suitable for processing stamping parts with complex shapes and numerous stamping processes, and it only needs one set of multi-station progressive dies.

So what are the advantages of this product? Its advantages are as follows:

1. Because it concentrates the multi-process punching die in a pair of die, it has higher working efficiency than ordinary composite die, and can produce stamping parts with complex design.

2. The operation is relatively safe, because human hands will not enter the dangerous area of processing.

3. When designing, the process can be dispersed, and it is not necessary to concentrate all the processes on one station, so it does not have the problem of wall thickness, and the use strength of the mold itself is relatively high, and the service life is high. Also longer.

4. It is easy to realize automatic production, that is to say, automation can be realized in terms of feeding, outputting and laminating.

5. It can be produced by a high-speed press, so that the leftover material or the workpiece can be directly leaked down.

6. The configuration of the press can be reduced, and the transportation of semi-finished products can also be reduced, which can help users reduce the workshop area and warehouse area.

Regarding the question of whether a stamping part needs to use a multi-station progressive die, we can consider the following aspects:

1. Design, manufacture and maintenance of molds

Because the mechanism of the mold itself is relatively complex, and the manufacturing accuracy is much higher than that of ordinary molds, it needs to be repaired and sharpened after each batch production, and can be put into use again after passing the test punch. Since the heights of the punch and the die are generally different, they should meet the original design requirements after sharpening. Therefore, if you want to use the die, the operator's operation is relatively high, and it also needs to be equipped with a precise special equipment.

2. Applicable presses

The press used should meet certain power, precision, strength and rigidity. The size of the worktable should be large, and the braking system should be reliable. However, the stroke of the punch should not be set too large, so that the guide system can work properly. can be effectively disengaged.

3. Good processed materials

Since there is no intermediate annealing in the manufacturing process, it is difficult to lubricate during operation. In order to ensure the quality of stamping parts, there are high requirements on the mechanical properties of stamping materials, and their performance must be relatively stable. Therefore, before processing, the material needs to be tested and inspected, and its width, thickness tolerance, and edge straightness must meet the requirements.
