Problems solved by technology

[0004] However, most of the existing research focuses on the influence of a single process parameter, such as holding temperature, stamping speed or holding pressure, on the quality of the formed part, but does not involve how multiple parameters work together to affect product quality; thus, this leads to

Abstract

The invention discloses a numerical method for fast determining process parameters of a hot punching production line. The method comprises the following steps of selecting process parameters to be determined and quality evaluation index parameters; determining a process parameter value range; performing random sampling to generate basic process parameter data; obtaining a data model of a product produced by the hot punching process production line under the condition of the basic process parameter; solving the average value of all index parameters in the data model; obtaining a mapping relationship between the basic process parameter and the index parameter average value; obtaining a process parameter reference value under the condition of the optimum index parameter; using the process parameter reference value as the basis to obtain the optimum practical process parameter. The method has the advantages that the hot punching process production line parameter data can be fast and scientifically determined; the mode process manufacturing and site debugging process can be obviously shortened; the product development process is accelerated; the product performance stability is ensured.

Description

technical field [0001] The invention belongs to a numerical method for rapidly determining process parameters of a hot stamping production line. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, the lightweight and safety of automobile body has become one of the important development directions of body design structural parts. [0003] At present, AHSS (Advanced high strength steel) structural parts are more and more used in the lightweight design of automobiles, the optimization of automobile collision safety and the improvement of automobile fuel economy due to their high tensile strength and small rebound in the process. more extensive. The most commonly used process for preparing this type of parts in engineering is hot stamping technology, which is a technology in which the sheet metal is stamped and formed at a high temperature, and then cooled rapidly to obtain a uniform martensite microstru...
