The transformation and upgrading of the automotive mold industry is promoted by five “chemical”
The automotive mold industry is the upstream industry of the automobile manufacturing industry. The quality of the mold directly determines the overall quality of the automobile. As China's auto industry continues to develop at the high end, the requirements for molds are also getting higher and higher. On the other hand, the ability of high-end mold design and development directly determines the quality of China's independent automobile brands. Promoting the continuous transformation and upgrading of the automotive mold industry cluster and promoting the development of mold products to the high-end, forward-looking researchers believe that the transformation and upgrading of the automotive mold industry is promoted has the following five key points:
(1) Design digitization
Affected by the wave of informationization and the impact of the global economic crisis, the domestic and international automotive mold industry has accelerated the pace of transformation and upgrading, and gradually developed into a digital direction in the cruel survival of the fittest. At present, the international automotive mold industry uses computer-aided technology to operate, and digital automotive mold technology can be summarized as follows: First is the manufacturability design (DFM), which considers and analyzes manufacturability during design, and guarantees the process. Success; followed by the auxiliary technology of mold profile design, to help develop intelligent profile design technology; in addition, CAE assisted analysis and simulation of stamping process, can predict and solve the defects and forming problems. In short, under the guidance of digital technology, it can well handle and solve problems in mold production and ensure the quality of mold products.
(2) Intelligent equipment
Equipment intelligence is the goal pursued by medium and high-end CNC in manufacturing in recent years. Equipment intelligence is mainly reflected in the following aspects: connecting high-end CNC equipment, such as high-speed, high-precision machining centers, high-stiffness, high-power online compensation technology; machine vision measurement (image capture, conversion, transmission); online quality Control system (such as infrared measurement); flexible fixture (seeking, processing image sensing, tightening system without positioning); intelligent scheduling, intelligent tool management (controllable, adjustable, efficient tool), intelligent network monitoring, etc. Formed an intelligent flexible production line.
(3) Process automation
Based on the numerical control of equipment, the process automation with the goal of punctualization and low cost is mainly manifested in the application of intelligent robots for workpiece feeding, automatic loading and unloading, rapid change of machining objects, quick adjustment of fixtures and tools. High-speed dry-cut superhard tools CBN (cubic boron nitride), PCD (polycrystalline diamond) tools are widely used. The logistics system is regulated by the intelligent production center to form process automation. Modern automobile manufacturing has six characteristics of high speed, high precision, automatic, composite processing, network and environmental protection. Take the rear axle of the car as an example: In the past, it required 10 processes, 5 machining centers, and 2 sleeper-forming production lines. Now only four processes are needed to complete the process and improve efficiency.
(4) Management modernization
Targeting the gradual and widespread adoption of new production methods such as lean manufacturing, agile manufacturing, virtual manufacturing, and network manufacturing is an important condition for companies to participate in international competition. At present, domestic enterprises have accumulated certain practical experience, and the gradual improvement of exchanges between enterprises will help promote the modernization of the entire industry management.
(5) Talent diversity
Automotive mold is a high value-added and technology-intensive product. It is the foundation of the autoamobile manufacturing industry. In recent years, China's mold technology has made great progress, and the mold design and manufacturing level has been greatly improved, but it is similar to foreign developed countries. There is still a certain gap, and one of the main reasons is the lack of talents in mold technology in China and the single talent structure. Talent diversification is the trend of adapting to social needs and talent innovation. In addition to introducing and cultivating technical and marketing talents, automotive mold enterprises must also focus on introducing and cultivating management talents, as well as strengthening the gender structure and knowledge culture structure of talents. And the optimization of the skill structure.
