A large amount of packaging used mainly in the food industry is obtained by technologies that involve the use of machines such as those that cut with flexible die. The durability of the flexible die is a very important aspect and in this regard the purpose of the research was to identify technologies for its development. Thus, the research considered the analysis of the durability of the knives made of 50CrMo4 steel considering hard chrome-plating treatment, as well as laser hardening of the knives. For the analysis of the durability of the tools, two technological parameters were considered, namely the moment of the tightening force, which had values in the range of 50 Nm–110 Nm, and the die cutting speed, which was adjusted to values in the range of 50–60 m/min. For the analysis of the durability of the flexible die, the wear of the tools was taken into account, as well as the maximum length of the die cut material.

提高印刷业用50CrMo4柔性模具耐久性的研究

主要用于食品行业的大量包装是通过涉及使用机器的技术获得的，例如使用柔性模具切割的技术。柔性模具的耐用性是一个非常重要的方面，在这方面研究的目的是确定其开发技术。因此，研究考虑了对考虑镀硬铬处理的 50CrMo4 钢制成的刀具的耐用性进行分析，以及刀具的激光硬化。为了分析工具的耐用性，考虑了两个技术参数，即拧紧力的力矩，其值在 50 Nm–110 Nm 的范围内，以及模切速度，其调整为50–60 m/min 的范围。对于柔性模具的耐久性分析，
