国内连杆模锻加工技术的现状及发展

Current Research and Progress of Connecting Rod Die Forging Domestic

连杆是在车辆上应用十分广泛的传力零件,其传力效果和质量、寿命等直接影响到动力机车的性能和质量,因此,对其强度、韧性、疲劳强度和重量有很高的要求。为了适应连杆的要求,出现了如模铸工艺、模锻工艺、粉末冶金等不同的加工工艺。由于模锻加工技术具有其他工艺无法比拟的优越性,在目前连杆生产中,占据主导的地位。本文从基础研究、精锻技术、数值模拟和裂解加工等方面对连杆模锻加工技术的国内研究进展进行了回顾和总结,并给出了今后的发展趋势。

The domestic development and progress of the die forging process of the connecting rod have been reviewed and summarized, which has been carried out at such aspects as basic research, precision forging, numerical simulation and fracture splitting process, with development and mainly research in each aspect given and the developing trend of the connecting rod set forth.
