摘要：

主要介绍了1寸以下法兰（法兰盘直径小于Φ130 mm）的闭式精锻工艺及其自动化生产应用中的关键问题。首先，根据锻件的特点设计锻件的加工余量为0.5～1.0 mm（不包括中间孔和拔模增加的余量），对比了一次锻造成形和两次锻造成形工艺的区别，确定成形工艺。然后，针对自动化生产的特点，总结工艺和模具设计中需要注意的一些问题并提出建议。最后，总结了自动化生产中容易出现的影响正常生产的问题，并提出建议。所设计的法兰闭式精锻工艺可以生产出合格的法兰精锻件，模具寿命也达到批量生产的要求，根据产品重量的不同，稳定生产节拍约在每小时300～400件。

The closed precision forging process of flange less than one inch (flange diameter less than Φ130 mm) and the key issues in its automatic production and application were mainly introduced. First, according to the characteristics of forgings, the machining allowance of forgings was designed to be 0.5-1.0 mm (not excluding the allowance added by the middle hole and draft), and the difference between one forging process and two forging processes was compared to determine the forming process. Then, according to the characteristics of automated production, some issues that needed attention in process and mold design were summarized, and the suggestions were given. Finally, the problems that easily occurred in automated production to affect normal production were summarized, and the suggestions were put forward. Thus, the qualified flange precision forgings were produced by the designed closed precision forging process of flange, the mold life met the requirements of automated mass production, and the stable production cycle was about 300 to 400 pieces per hour according to the difference in product weight.
