A hot stamping method based on sheet metal

Abstract

The invention discloses a heating stamping method based on a metal plate, which belongs to the technical field of plate stamping. It is a heating stamping method based on a metal plate. By installing a paint spraying device on one side of an upper mold base, the hot stamping forming of the plate Finally, the upper mold base drives the stamping punch to separate from the lower mold base, and rotates the upper mold base so that the paint spraying device faces downward. The paint spraying device sprays paint on the plate that has not been completely cooled. Since the plate still has a certain temperature, It has a certain degree of thermal expansion, which is easy to improve the gripping force between the paint and the board. After the board is completely cooled, the paint can be tightly attached to the board, and then the second spraying after cooling can effectively improve the quality of the spray paint, and the operation It is simple and orderly, and there is no need for painting treatment in the later stage. In addition, a plate conveying mechanism is set on the side of the lower mold base, and then manual handling is not required when picking and placing the plates.

Description

technical field [0001] The present invention relates to the technical field of plate punching, and more specifically, relates to a heating stamping method based on a metal plate. Background technique [0002] Stamping processing in mechanical processing occupies an important position in the processing industry of the national economy. Metal sheet metal parts are often obtained by traditional cold stamping methods. By designing different types of molds, they are produced using conventional equipment such as mechanical presses and hydraulic presses. When the production batch is large, it has the advantages of high efficiency and low cost. [0003] The application fields of sheet metal parts are extremely wide, and they penetrate into all aspects of the manufacturing industry. Sheet metal forming is mainly realized by stamping dies. , has a series of advantages such as high precision, high efficiency, good quality, cost saving, material saving and energy saving. [0004] The ...

AI Technical Summary

Problems solved by technology

[0004] The stamping technology in the prior art is to heat the plate and place it in the stamping die for direct stamping, and spray paint after cooling and demoulding. However, in the prior art, chapping tends to occur on the end surface of the plate after the coating is sprayed. The coating effect is poor; in addition, in the hot stamping process, it is not easy to transfer the plate with temperature. If it is directly transferred manually, improper operation may easily cause burns. If it is transferred by a robot, due to the limited space above and below the mold, the robot Occupies a large space and is often inconvenient for the smooth placement of the panels
