简介:研究了流动温压工艺的成形温度对W-34Ni-5Fe混合粉末横向压力的影响及横向压力和生坯密度在横向距离上的分布,并进行了带螺纹孔的十字形零件的成形实验。实验结果表明,流动温压成形时,混合粉末在横向距离上存在较大的压力分布,流动温压工艺在十字形零件的纵向和横向都能成形出完好的内螺纹。
简介:摘 要:针对传统的高速铁路道岔钢轨跟端高温热锻成形生产现状,设计了一套钢轨跟端热锻成形自动化检测设计方案。该方案在不改变原有的生产线生产模式下增加一套钢轨跟端热锻成形自动化检测方式设计,将传统的钢轨跟端检测方式进行优化设计,实现自动化在线检测。有效的降低了操作工人的劳动强度,同时也改善的生产环境,提高生产效率和对工人的安全指数。
