Description

Technical Field

[0001] This invention relates to the field of metal sheet stamping and forming technology, specifically a metal sheet stamping and forming composite equipment. Background Technology

[0002] Metals are substances that possess luster, ductility, and good electrical and thermal conductivity. The vast majority of metallic elements on Earth exist in nature in a combined state. This is because most metals are chemically reactive, with only a very few, such as gold and silver, existing in a free state. Metals are widely found in nature and have extremely common applications in daily life, making them a very important and widely used class of substances in modern industry. Before metals can be used in people's daily lives, they need to undergo various processing steps. In the processing of metal sheets, stamping and bending are necessary.

[0003] Existing technology utilizes a punching and folding structure to simultaneously punch and fold thin metal materials, achieving integrated punching, folding, and cutting. This reduces the need for separate cutting processes and improves processing efficiency. Furthermore, the guide structure guides the thin metal material, ensuring it enters the processing area correctly. This guide structure also automatically transports the material to the processing area, eliminating the need for manual feeding and further enhancing processing efficiency.

[0004] However, in actual use, the guide structure and the feeding structure work together to drive the metal plate. During processing, metal plates of different thicknesses are often encountered. The guide structure and feeding structure in the above design are not easy to adjust to drive metal plates of different thicknesses.

[0005] Therefore, a metal sheet stamping and bending composite forming equipment is proposed to address the above problems. Summary of the Invention
