Metal sheet warm forming device based on induced high-frequency electromagnetic field

Abstract

The invention provides a metal sheet warm-hot forming device based on an induced high-frequency electromagnetic field. A vertical-through stamping opening is formed in a workbench; a support frame comprises an upper supporting plate above the workbench, a lower supporting plate under the workbench, and connecting rods connected with the workbench in a sliding manner; two ends of each connecting rod are respectively connected with the upper supporting plate and the lower supporting plate in an assembling manner; a male mold forming assembly comprises a male mold, a mold guiding plate and a blank holder; the male mold is arranged right above the stamping opening and movably connected with the upper supporting plate; the mold guiding plate is arranged on the edge of the stamping opening and movably connected with the workbench; the blank holder is arranged above and movably connected with the mold guiding plate; and a high-frequency electromagnetic field generator is arranged just under the stamping opening and connected with the lower supporting plate in an assembling manner. The metal sheet warm forming device has the beneficial effects that a metal sheet stamping process can be simplified; limitation of stamping part production lot can be avoided; metal sheet stamping cost can be reduced; metal sheet stamping efficiency can be improved; the metal sheet warm forming device is also suitable for stamping forming of plates which are high in strength and difficult to form, and stamping parts obtained after stamping forming are excellent in quality.

Description

technical field [0001] The invention relates to the technical field of metal sheet stamping and forming, in particular to a metal sheet warm forming device based on an induced high-frequency electromagnetic field. Background technique [0002] Sheet metal stamping is an important plastic processing technology for sheet metal, which is widely used in the field of machining. Nowadays, the demand for some sheet metal forming products is not large, and stamping processing can only fully reflect the advantages of stamping processing 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 the cost of product development. 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, with the increasing r...

Problems solved by technology

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.
