冲压噪声最主要的声源之一是模具工作部分冲压时分离或变形金属板产生的刚性冲击,推广使用低噪声冲模,是消减冲压噪声行之有效的措施。本文根椐实际统计和测试结果,结合国内目前情况与实际需要,介绍国外推广的一些低噪声模及其实测减噪效果;针对国内冲压设备结构特点及冷冲模标准,推荐优先采用的低噪声冲模结构,非标准低噪声冲模结构设计与计算等,供参考。 Stamping noise is one of the most important source of noise when the mold part of the stamping metal plate deformation or deformation of the rigid impact of the promotion of the use of low-noise die, stamping noise reduction is an effective measure. Based on the actual statistics and test results, combined with the current situation in our country and actual needs, this paper introduces some low noise modes popularized abroad and the measured noise reduction effect. According to the structural characteristics of the domestic stamping equipment and the standard of cold die, we recommend the low noise die Structure, non-standard low-noise die structure design and calculation, for reference.
