摘要
主要介绍了齿轮件自由锻的基本工序:镦粗—垫环镦粗—冲孔—冲子扩孔—修整。设计与绘制了锻件图,计算了坯料尺寸,确定了锻造温度范围和所需要的自由锻设备,并介绍了带锯下料,感应加热。
The essential process of forging a gear in an opening die is upsetting,backing ring upsetting,punching,bore enlarging by punch,and trimming.The forging drawing of the part,the dimension of the blank,the range of the forging temperature,the equipment needed,the blanking process with band saw,and the induction heating of the workpiece are mentioned in this paper.
