Die digital processing and forming technology

Mold processing technology can directly affect the comprehensive benefits of manufacturing links, so it is necessary to carry out digital transformation of mold processing links. Take the high-speed machining of the processing link as an example. Compared with CNC machining, high-speed machining can fundamentally improve the processing efficiency, improve the precision and quality of the machined surface, and simplify the original processing process. However, at present, high-speed processing will also lead to the shortening of the service life of the original tool material, and the actual production cost will be further improved. Therefore, during the development of digital machining of molds at this stage, it is necessary to combine customer requirements and shift the focus of digital development to improve the machining performance of machine tools and measure the high-speed cutting level.

High-speed machining advanced processing technology, so that the traditional mold processing link has undergone a great change. In order to give full play to the application importance of digital processing technology. Mold manufacturing enterprises also need to place the current development goals in the following aspects:

First, reasonable control of processing parameters. According to the requirements of high-speed machining of die, a complete table of high-speed machining parameters is developed. By analyzing the existing machining examples, the cutting target of high quality and high efficiency can be achieved by carrying out a large number of test cutting control parameters.

Second, choose the appropriate cutting tool. The cutting principle of high-speed cutting is different from that of traditional cutting, and there are great differences in machining wear mechanism, failure form and tool stress state. Therefore, in order to ensure the high-quality and efficient development of high-speed machining links, it is also necessary to select the appropriate cutting tools, maximize the service life of the tool, and play the tool performance;

Third, reasonable planning of knife position path. It is required that in the process of tool position path planning, it is necessary to analyze the high-speed cutting characteristics to ensure that the selected tool path is smooth and there are no more turning points. Ensure the accuracy of the program algorithm, control the feed speed of the tool, and avoid this problem of the props.

Digital analysis technology of mold plastic forming

In the process of mold processing, the metal plastic forming mechanism is more complex, and the traditional mold processing link needs to rely on years of research experience to carry out detailed analysis of plastic forming, resulting in a long product development cycle and high development cost. By applying digital manufacturing technology in the mold molding process, the mold development cycle can be further shortened and the understanding of product performance can be strengthened.

According to the mechanical state of metal plastic deformation, the plastic forming technology is divided into two kinds: volume forming and sheet metal forming. In the process of studying the metal plastic deformation law, the physical experiment method and theoretical analysis method are mainly used, combined with the nonlinear plastic finite element data, the material hardening effect, the model and the friction boundary condition are fused together, so that the metal flow law of the mold manufacturing process can be effectively predicted.
