模具标准(翻译资料)

ncouraged when piloting in hardened tool steel, based on design constraints. 设计上应限制:在热处理后的模板上导正时应使用嵌套。 8. All pilots must bea minimum 5/16 ” diameter. 所有的引导冲直径至少为 5/16 ” 9. Only tooling holes may be used to pilot. Repiercing toa larger size when piloting plete, is allowed. 仅仅废料上的孔用作导正孔,当导正结束后,在导正孔上冲一个大的孔是可以接受的。 10. Progressive dies will have sled type stock lifters after trim operation. Stock lifters should have a rounded top with a diameter sufficient to cover trim out area or sled lifter to be used. 连续模在剪边后应使用雪橇式的浮升块,条料浮升销的头部面积应比剪开面积大或使用雪橇式的浮升装置。 11. Progressive dies will have a coil start line marked on die(s) or on the guide rails. 连续模在模板或导轨上刻一个卷料起始线。 13. A pierced pilot hole shall be the first station ofa progressive die to ensure proper pitch from die setup. 在连续模第一站应冲导正孔确保模具结构有固定的步距。
