Description

Automatic continuous stamping forming system

This creation is related to the stamping and forming mechanism, especially a fully automatic continuous stamping and forming system.

Pressing, the conventional stamping device, such as the "Stamping Continuous Forming Device without Stamping" disclosed in Chinese Patent No. M577771, which mainly includes a feeding unit, an upper die base, a lower die base and a feeding unit. The feeding unit is used for stacking the metal sheets that have been cut into sheets in advance. The upper mold and the lower mold are provided with corresponding modules in sequence. The feeding unit separates the metal sheets in the placing unit one by one. Pushed between the upper mold and the lower mold, so that the metal sheet is pressed by different molding modules of the upper mold in sequence, and then passes through the prototype and semi-finished products until it is shaped into a hollow cylindrical finished product.

However, the structure disclosed in the above-mentioned prior art can only punch the metal sheet into a hollow cylindrical shape, but before being cut (or punched) into a sheet, the metal sheet is in the form of a whole roll of belt, so The entire roll of metal sheet must be cut into sheets on other machines before it can be transported and stacked on the placing unit. The cutting and stamping operations of the metal sheet are not carried out on a continuous mechanism, resulting in the need to purchase two sets of independent mechanisms (one for cutting the metal sheet and one for the stamping and forming metal sheet) to increase the cost. And the metal sheets must be transported and stacked between the mechanism of cutting operation and the mechanism of stamping and forming by manpower, which has the problem of wasting manpower.

In addition, in the aforementioned conventional mechanism, after being pressed by various molding modules in the upper mold, the metal sheet passes through the prototype and semi-finished products until it is molded into a hollow cylindrical finished product. Therefore, great power must be exerted on the module to form and fix the original sheet metal sheet into a hollow cylindrical finished product. However, too much force is applied to easily damage the module, which greatly reduces the service life of the module, and the downtime and cost of frequent replacement of the module increase, and the yield of the finished product is not good.
