摘要
3104铝合金罐体料在生产过程中控制不当,制罐厂冲罐过程中容易出现划模缺陷。划模缺陷是制罐厂变薄拉伸后的罐体在修边过程中,罐口的裂边没有完全切干净,到缩颈/翻边工序时,裂边将缩颈/翻边的模具划伤,划模缺陷会严重影响生产效率。作者从3104铝合金罐体料在生产过程中厚度测量值、同板差指标、宽度要求、制耳率指标、冲罐模具匹配等方面分析了产生划模缺陷的原因,根据划模缺陷产生的原因提出了相应的预防措施,使划模缺陷得到有效控制。
Due to improper control of 3104 aluminum alloy can material in the production process,the die-scratching defects are easy to occur in the process of pot punching in the tank factory. When the thinned and stretched cans are incompletely edge-trimmed,the edge burr will make dies scratched in the necking/flanging process. The die-scratching defects will seriously affect the production efficiency. The causes of die-scratching defects in 3104 aluminum alloy cans were analyzed from the aspects of thickness measurement value,same sheet difference index,width requirement,ear-making rate index and matching of punching die. According to the causes of die-scratching defects,the corresponding preventive measures were put forward to effectively control the scratching defects.
