提高模具寿命途径有哪些？

What are the ways to improve die life?

模具寿命的高低不仅是衡量模具质量的重要指标之一，而且在一定程度上反映了一个地区、一个国家的冶金工业和机械工业水平。目前，我国已成为世界模具制造大国，但还不是强国，我国模具的制造水平和使用寿命与先进国家相比，还有很大的差距，模具质量较低，使用寿命只有先进国家的1/5~1/2。据统计，在我国由于模具寿命低而造成的钢材、工时和能源浪费，以及由此对产品质量影响所带来的损失，每年达数十亿元；并且严重降低了产品生产效率，直接影响企业的经济效益和竞争力。因此，提高模具寿命是模具制造业中亟待解决的问题。

Die life is not only one of the important indicators to measure the quality of dies, but also reflects the level of metallurgical industry and mechanical industry in a region or a country to a certain extent. At present, our country has become a big country of mould manufacturing in the world, but it is not a powerful country. Compared with advanced countries, there is still a big gap in the level of mould manufacturing and service life. The quality of mould is low, and the service life of mould is only 1/5-1/2 of that of advanced countries. According to statistics, the waste of steel, man-hour and energy caused by the low life of dies and moulds in our country, as well as the loss caused by the impact on product quality, amounts to billions of yuan every year, and seriously reduces the production efficiency of products, directly affecting the economic benefits and competitiveness of enterprises. Therefore, improving die life is an urgent problem to be solved in die manufacturing industry.

近年来，模具的应用领域不断扩大，随着国家产业政策的调整，航空航天、新能源、IT、医疗机械、高速铁路等行业，对模具的质量、品种、供货期提出了更高、更多、更快的要求，精密、大型、复杂、长寿命已经成为现代模具制造的主题。如何提高模具的加工质量和使用寿命，一直是模具工作者不断探索的课题。大量失效模具分析结果表明，模具材料与热处理对模具寿命的影响占有重要地位。

In recent years, the application field of mould has been expanding. With the adjustment of national industrial policy, aerospace, new energy, IT, medical machinery, high-speed railway and other industries have put forward higher, more and faster requirements for the quality, variety and delivery period of mould. Precision, large-scale, complex and long-life have become modern mould. The theme of manufacture. How to improve the processing quality and service life of dies has always been the subject of continuous exploration by die workers. A large number of failure die analysis results show that the influence of die material and heat treatment on die life occupies an important position.

模具材料是模具制造的基础，其品种、规格、质量对模具的性能、使用寿命起着决定性的作用，正确的热处理技术是保证模具获得所需性能和寿命的关键。因此，为了使模具获得良好的使用性能和长的使用寿命，除了合理设计模具结构外，还应选用合适的模具材料与热处理技术。目前，随着新材料的应用及模具制造技术的不断完善，在原有常规的热处理基础上，通过热处理优化模具材料的组织和性能，并相继开发和应用一大批实用、先进的热处理新技术，使模具寿命得到大幅度提高。

Die material is the basis of die manufacturing. Its variety, specification and quality play a decisive role in the performance and service life of the die. Correct heat treatment technology is the key to ensure the required performance and service life of the die. Therefore, in order to obtain good service performance and long service life of the die, in addition to reasonable design of the die structure, appropriate die materials and heat treatment technology should also be selected. At present, with the application of new materials and the continuous improvement of die manufacturing technology, on the basis of conventional heat treatment, the structure and properties of die materials are optimized by heat treatment, and a large number of practical and advanced heat treatment technologies are developed and applied successively, which greatly improves the die life.

模具制造的成本较高，特别是一些精密复杂的冲裁模、塑料模、压铸模等制造成本更高。通过采用先进的模具材料与热处理技术提高模具寿命，可以显著降低模具成本，具有显著的经济效益。改革开放以来，我国十分重视模具材料与热处理技术的发展，国内外先进的模具材料、热处理工艺与装备得到了广泛的应用，各种强韧化工艺和表面强化处理技术得到了推广，从而显著提高了模具的使用寿命。

Mold manufacturing costs are higher, especially for some precise and complex blanking dies, plastic moulds, die-casting dies and other manufacturing costs are higher. By using advanced die materials and heat treatment technology to improve die life, die cost can be significantly reduced, with significant economic benefits. Since the reform and opening up, China has attached great importance to the development of die materials and heat treatment technology. Advanced die materials, heat treatment processes and equipment have been widely used at home and abroad. Various toughening processes and surface strengthening treatment technologies have been promoted, thus significantly improving the service life of the die.

本书作者根据三十多年在热处理领域所积累的实践经验，并参考国内外有关模具材料与热处理方面的文献资料编写了本书。本书全面介绍了常用模具材料及其热处理与应用，典型模具的选材及热处理技术，以及提高模具寿命的途径与方法。通过合理选材及采用模具新材料，并实施正确和先进的热处理技术，可以充分发挥模具材料的潜力，提高模具使用性能，使模具寿命提高几倍甚至几十倍。

The author has compiled this book on the basis of more than 30 years'practical experience in the field of heat treatment and referring to domestic and foreign literature on die materials and heat treatment.
