本文介绍了190、240型柴油机连杆锻件中心距超长的情况,从我厂的生产实践分析了大中型连杆锻件中心距收缩率的影响因素,并提出了解决问题的方法。最后总结了中心距收缩率合理参数,以供设计锻模时参考。
This paper introduces the situation that the center distance of 190,240 diesel engine connecting rod forgings is extremely long. The influencing factors of center distance shrinkage of large and medium sized connecting rod forging are analyzed from the production practice in our factory, and the methods to solve the problems are put forward. Finally, a summary of the center from the shrinkage rate of reasonable parameters for the design of die for reference.
