摘要

锻造工具必须能够承受非常强的机械、热、摩擦和化学应力。工具能够承受这些应力的程度取决于所使用的材料及其预处理以及热处理和表面处理,即负载能力。应力与承载能力的比值决定了锻造工具的使用寿命有多高。本文以某一特定工业阶段顺序和生产条件为例,讨论了锻件刀具寿命的变化。由于在刀具的整个生命周期中对刀具产生影响的影响变量很多,因此本文的研究重点放在了成形过程的影响变量上。根据调查期间某锻件公司实际生产参数的记录,分析了工艺数据对刀具寿命的影响。研究的重点是四个影响变量,即对刀具寿命结束的主观评估、成形阶段之间的相互作用、生产中断以及成形工具的冷却和润滑。对于试验中尚未记录的参数,在实验室条件下确定并测试了有希望的可用测量方法。这方面的一个例子是记录在成形过程之前喷到工具表面的实际喷量。研究结果表明,刀具寿命波动可减少约16%,平均刀具寿命可提高约13%。

Investigation of Forging Tools on the Basis of Subjective Assessment of Tool Life
Forging tools must be able to withstand very strong mechanical, thermal, tribological, and chemical stresses. The extent to which a tool can withstand these stresses depends on the material used and its pre-treatment as well as the heat and surface treatment, i.e. the load capacity. The ratio of stress to load capacity determines how high the tool life of a forging tool is. This paper deals with the variations in the tool life of forging tools using the example of a specific industrial stage sequence and production conditions. Due to a large number of influencing variables that have an effect on the tool during the entire tool life history, the focus of this work is placed on influencing variables of the forming process. Based on real production parameters of a forging company, which are recorded during a period for the investigation, the process data are analyzed about an influence on the tool life. The investigation focuses on four influencing variables, namely the subjective assessment of the end of the tool life, the interaction between the forming stages, production interruptions, and the cooling and lubrication of the forming tools. For the parameters that are not yet recorded during the trials, promising available measurement methods are identified and tested under laboratory conditions. One example of this is the recording of the actual spray quantities that are sprayed onto the tool surface before the forming process. The results of the investigations show that the tool life fluctuations can be reduced by about 16% and as a consequence, the average tool life can be increased by about 13%.
