高速级进冲压生产中的废料回跳会影响制件的质量和冲压生产的正常运行。文章分析了高速级进冲压废料出现回跳现象的原因,并根据生产实践经验,从增大废料回跳阻力、使废料受到向下的外力、凸凹模刃口形式等方面,总结出了抑制废料回跳的措施。在保证废料不回跳的前提下,应充分考虑所用方法的经济性、模具的寿命长且易于维护,并根据模具工作的具体条件,选择相应的抑制废料回跳的方法或多种方法的综合运用来抑制废料回跳。

The scraps bounce in high speed and progressive stamping will influence the quality of the workpieces and normal operation of the stamping.The reason of the scraps bounce was analyzed,and based on the practical experiences,the methods of suppressing to scraps bounce by increasing resistance of scraps bounce,giving the external and down force to the scraps and achieving the form of cutting edges of the punch and die,etc.were summerized.Provided that the scraps donot bounce,the methods adopted will fully consider the matters of the economical state,life of the mold and easily maintenance.According to the working conditions of the mold,the corresponding method or comprehensive methods were chosen to restrain scraps bounce.
