Warm and hot forming device for sheet metal based on induced high-frequency electromagnetic field

Abstract

The invention proposes a metal plate warm forming device based on induced high-frequency electromagnetic field. The workbench is provided with punching openings that penetrate up and down. The plate and the connecting rod slidingly connected with the workbench, the two ends of the connecting rod are respectively assembled to connect the upper supporting plate and the lower supporting plate, the punch forming assembly includes a punch which is located directly above the punching port and is movably connected with the upper supporting plate, located at the punching The guide plate on the edge of the punching port is movably connected to the workbench, the blank holder is located above the guide plate and is movably connected to the guide plate, and the high-frequency electromagnetic field generator is located directly below the punching port and is assembled and connected to the lower supporting plate. The beneficial effects of the present invention are: the sheet metal stamping process can be simplified without being limited by the production batch of stamping parts; the stamping cost of the sheet metal can be reduced, and the stamping efficiency of the sheet metal can be improved; The stamping parts after forming are of good quality.

Description

technical field [0001] The invention relates to the technical field of sheet metal punching and forming, in particular to a warm forming device for sheet metal based on an induced high-frequency electromagnetic field. Background technique [0002] Sheet metal stamping is an important plastic processing technology of sheet metal, which is widely used in the field of mechanical processing. Nowadays, the demand for some plate forming products is not large, and the advantages of stamping processing can be fully reflected only when the production batch of stamping parts is large, so as to obtain better economic benefits. At the same time, the processing and manufacturing industry is constantly striving to shorten the product market cycle and reduce product development costs. However, when using the traditional rigid die stamping method, the cost of forming is high, and the design and manufacture of the die requires a lot of time and cost. . In addition, as the requirements for ...

At the same time, the processing and manufacturing industry is constantly striving to shorten the product market cycle and reduce product development costs. However, when using the traditional rigid die stamping method, the cost of forming is high, and the design and manufacture of the die requires a lot of time and cost.

In addition, as the requirements for sheet metal forming products become higher and higher, a large number of high-strength, difficult-to-form sheet metal forming materials are put into use, which increases the requirements for traditional sheet metal stamping and forming processes.

These high-strength metal sheets have high yield stress and good strength, but their stamping performance is poor and difficult, and they are prone to cracking, especially the defects such as wrinkling and springback are more significant, which directly affect the quality of high-strength sheet metal stamping parts.
