我厂生产的模具一般都使用9Mn2v材料做上下模,由于容易磨损,寿命比较短。在“工业学大庆”运动中,为了配合冲床技术改造,模具车间职工,结合生产的特点,对产量较大的另件设计成功了硬质合金自动送料级进模。模具冲头和凹模均使用YG20硬质合金,有切边、冲孔、导正、落料四个工步。生产率高,模具寿命长,并能減轻劳动强度,保证安全生产,达到了消灭冲床“老虎口”的目的。
I plant the production of molds are generally used 9Mn2v material to make the upper and lower mold, due to easy wear and tear, shorter life expectancy. In the “Daqing Industrial” campaign, in order to meet the punch technology transformation, mold shop workers, combined with the characteristics of production, the larger yield of the other pieces of the successful design of carbide automatic feed progressive die. Die punch and die are used YG20 cemented carbide, trimming, punching, guiding, blanking four steps. High productivity, long mold life, and can reduce labor intensity and ensure safety in production, reaching the purpose of eliminating punch “tiger mouth.”
