Stamping technology development history and characteristics
The industrial production of automobiles is really the development of stamping technology.
At the beginning of the 20th century, the industrial production of Ford Motor Company greatly promoted the research and development of rushing. The research work is basically carried out in both sheet forming technology and formability. The key issues are cracking, wrinkling and rebound, involving the formation of shapeability, the innovation of forming methods, and the analysis and control of the forming process.
In fact, in most of the 20th century, the mastery of stamping technology is basically empirical. The analytical tool is a classical theory of forming mechanics, and the problems that can be solved are very limited. The focus of the research is on Sheet metal stamping performance and forming mechanics, which are far from meeting the needs of the automotive industry.
The 1960s was an important period in the development of stamping technology, and various new forming technologies appeared one after another. In particular, the introduction of the forming limit diagram (FLD) has promoted the coordinated development of sheet properties, forming theory, forming process and quality control, and has become a milestone in the history of stamping technology development.
Due to the early development of finite element method and CAD technology in the 1980s, numerical simulation and centering and computer application technology in the 1990s have been rapidly developed and put into practical use in the field of stamping, becoming a powerful tool for material deformation behavior research and process design. . Auto stamping technology has really entered the analysis stage, and traditional sheet forming technology has begun to move from experience to science.
The characteristics can be seen from the development of stamping technology as follows:
(1) The research and improvement of stamping performance are complementary to the development of stamping technology.
(2) The development of stamping technology involves materials, energy, molds, equipment and other aspects. The innovation of process methods and the scientific analysis and control of its processes are the core of technological development; mold technology is the embodiment of the development of stamping technology and an important factor in determining the manufacturing cycle, cost and quality of products.
(3) The rapid development of industries such as automobiles and airplanes, as well as energy factors, are the main driving forces for the development of stamping technology. In the new century, environmental factors and related legal constraints have become increasingly prominent, and lightweight design and manufacturing of automobiles has become an important issue at present.
(4) The development of digital simulation technology in the forming process, promoting the traditional stamping technology to become scientific and enter the ranks of advanced manufacturing technology.
