提高自由锻锤上固定模寿命的途径

Ways of Improvement of Upper Fixed Die Life of Smith Forging Hammer

介绍了提高自由锻锤上固定模寿命的途径。主要从以下五个方面说明 :在锻模设计中应合理选择分模面、适当增大出模斜度和适当增大圆角 ;在锻模结构中应设导向定位锁扣、模块四周做成大圆角和型槽定位中心 ;在使用条件中应对锻模进行合理的预热、润滑和冷却 ;在设备条件中说明锻锤吨位的计算方法和锻模的安装状态 ;在制造技术中说明模块选材和软氮化处理。

Ways of improvement of life of upper fixed die of smith forging hammer has been introduced in followig five sections:rational selection of parting surface, proper increase of stripping taper and round edge in design of forge die;equipping die structure with guiding-locating-locking, all around die blocks with large round edge and locatig centre; proper pre-heating, lubricating and cooling of die working conditions;calculating method of hammer tonnage and installing status of die written clearly in equipment conditions; die material selection and soft nitrogen treatment described in manufacture technique.
