Problems solved by technology

[0008] However, the existing progressive dies have limitations when forming products with complex shapes, especially when materials with low formability such as ultra-high tensile steel materials are applied to the progressive process, due to the low Formability has the following disadvantages: Not only are cracks easily generated, but also the processing accuracy and molding quality are greatly reduced.

Abstract

The invention provides a progressive die machine and a progressive forming method. The progressive die machine improves forming quality of a low formability material such as an ultra-high strength steel material, or the like, and enhances productivity by adopting rapid heating to a progressive method. The progressive die machine includes: a lower die; an upper die installed to vertically reciprocate with respect to the lower die; a material transfer unit to sequentially transfer a material in a length direction between the upper die and a lower die; a plurality of forming stations installed in the upper die and the lower die; and a rapid heating station installed to be adjacent to at least one of the plurality of forming stations.

Description

technical field [0001] The present invention relates to a progressive die device, and in more detail, to a progressive forming device and a forming method thereof: rapid heating is adopted in the progressive process, thereby enabling to ensure low formability of materials such as ultra-high tensile steel materials. material) molding quality, and can greatly improve product productivity. Background technique [0002] In order to improve the fuel economy of automobiles, it is required to reduce the weight of the vehicle body, chassis, etc. As the most effective method for this weight reduction, there are proposals such as using materials with low specific gravity or making materials thinner than before. . [0003] The use of a material with a low specific gravity has the disadvantage of greatly increasing the cost, and the method of making the thickness of the material thinner than before has the disadvantage of weakening rigidity although it is easy to secure strength by usi...
