Abstract
In the automobile manufacturing industry, stamping die as a key process equipment, its design and optimization is directly related to production efficiency, product quality and manufacturing costs. With the increasing demand for lightweight, high-strength and complex structural parts in the automotive industry, the design of stamping die is facing unprecedented challenges and opportunities. This paper deeply discusses the core elements of stamping die design, including die structure layout, material selection, molding process analysis, as well as die accuracy and life control, aiming to improve the performance of the die through comprehensive optimization strategy, to meet the high efficiency and intelligent development trend of automobile manufacturing. In the die structure layout, how to reduce the material flow resistance and improve the forming accuracy and surface quality of stamping parts through reasonable profile design and guide system configuration is studied. At the same time, aiming at the application of high strength steel plate, aluminum alloy and other new materials, the selection principle of die materials and the influence of heat treatment process on the wear resistance and fatigue resistance of die were discussed. In addition, computer aided engineering (CAE) technology is used to simulate and analyze the molding process of the mold, predict and solve potential molding defects, such as wrinkling, cracking, etc., to achieve precision and efficiency of mold design. In terms of optimization, this paper proposes a mold life prediction and maintenance optimization strategy based on big data and artificial intelligence. Through real-time monitoring and analysis of the data during the use of the mold, potential faults can be identified in advance to achieve preventive maintenance of the mold. At the same time, combined with the modular and standardized design concept, improve the versatility and interchangeability of the mold, reduce manufacturing costs, shorten the development cycle. The design and optimization of stamping die in automobile manufacturing is a systematic project, which needs to start from various aspects, comprehensively use advanced technology and management means, and constantly improve the performance of the die to meet the needs of the rapid development of the automobile industry.
