Drawing and shaping mold structure

Abstract

The invention discloses a drawing and shaping mold structure, which comprises a terrace die (1) and a die (2), wherein the die (2) is divided into two half moulds in a jogged structure, the combination surface of the two half molds is a die partingsurface (8), the die partingsurface (8) is vertical to the separation-combination plane of the terrace die (1) and the die (2), a fastening screw bolt (3) is arranged on the die (2), and the two half molds of the die (2) are tightly fastened and connected. When the technical scheme is adopted, the die is separated and is connected and fixed through the fastening screw bolt, the fastening screw bolt is provided with a theoretical ultimate fracture point, and the expansion crack of the die can be avoided under the risk of double-material occurrence of the mold. The invention is applicable to vertical beam type parts on automobiles, particularly U-shaped beam type parts. The damage on the die by the double materials is avoided through the fracture of the fastening screw bolt, so the risk-resistance capability of the mold can be effectively improved, the die can not be damaged even if the fracture of the fastening screw bolt occurs, and the mold production can be fast recovered.

Description

technical field [0001] The invention belongs to the technical field of pressure manufacturing process equipment, and relates to a die structure technology for cold stamping processing, more specifically, the invention relates to a drawing forming die structure. Background technique [0002] At present, with the rapid development of the automobile industry, all major automobile manufacturers are engaged in all-round competition in terms of brand, service, quality, and cost. As the focus of investment in the production preparation process, how to ensure the manufacturing quality of molds and effectively improve the anti-risk ability of molds has also become the subject of research by major automobile manufacturers and mold manufacturers. [0003] Due to the technical requirements for the development of body parts, the number of parts in the product development of longitudinal beams and U-shaped beam parts is relatively large, and with the development trend of new product techn...

Problems solved by technology

[0004] When the double sheet is put into the die, the die will be in danger of expanding. In the new product mold debugging and production preparation stage, due to the high probability of double materials in the production process, the conventional drawing die structure, the die is integrally cast, for longitudinal Under the risk of double materials on beams and U-shaped beams, the die will be swollen and cracked, which will greatly affect the life of the mold and the quality of the parts in the later stage. In severe cases, it will affect the speed of the model to market

[0005] Therefore, in the process of debugging and production preparation, the traditional stamping and drawing die structure has a poor ability to resist the risk of bursting of the above-mentioned double materials, and basically cannot avoid the risk of the die being burst.
