摸清情况明确赶超方向随着我国机械工业高速度地发展,各工厂铸工车间的机械化程度也有了很大的提高。代替手工操作的各种抛丸、喷丸(砂)清理机械的应用日益普遍。实践表明,它用在铸件、锻件、热处理件、板金件的表面清理方面,不但大大地提高了清理效率和清理质量,而且也有效地改善了工场卫生环境,减少了工人的职业病和降低劳动强度。但就目前国内情况来看,抛丸清理机械易磨损,另件的寿命很低。以抛丸叶片为例,大部份工厂只有5—10小时,个别厂达60—70小
Clear situation clear catch-up direction With the rapid development of China’s machinery industry, the mechanization of the plant casting workshop has also been greatly improved. Instead of manual operation of a variety of shot blasting, shot peening (sand) cleaning machinery applications are increasingly common. Practice shows that it is used in the casting, forgings, heat treatment, sheet metal surface cleaning, not only greatly improve the cleaning efficiency and clean-up quality, but also effectively improve the sanitary environment of the factory, reduce occupational diseases and reduce labor intensity . However, the current domestic situation, shot blasting machinery easy to wear and tear, the other life is very low. Blasting leaves, for example, most of the factory only 5-10 hours, individual factory of 60-70 small
