冷挤(ji)压(ya)工(gong)(gong)步大抵(di)可可分(fen)(fen)断(duan)(duan)联工(gong)(gong)步和(he)成(cheng)型(xing)工(gong)(gong)步（又(you)分(fen)(fen)迂回曲折、拉深、成(cheng)型(xing)）两个(ge)类(lei)。断(duan)(duan)联工(gong)(🍃gong)步是在冷挤(ji)压(ya)程序运行中使冷挤(ji)压(ya)件与坯料沿肯定的(de)外表线相互断(duan)(duan)联，同样(yang)冷挤(ji)压(ya)件断(duan)(duan)联截(jie)面的(de)质(zhi)量(liang)就要知足肯定的(de)需(xu)(xu)求；成(cheng)型(xing)工(gong)(gong)步是使冷挤(ji)压(ya)坯料以(yi)不会(hui)磨(mo)碎的(de)基本前提颁发生弹塑性磨(mo)损，并图片转换成(cheng🎃)所需(xu)(xu)求的(de)产品(pin)外表，同样(yang)也应(ying)知足规格(ge)公役(yi)等部分(fen)(fen)的(de)需(xu)(xu)求。
要根据冷(leng)(leng)(leng)模具(ju)冷(leng)(leng)(leng)冲(chong)压(ya)时(shi)的体温生态有冷(leng)(leng)(leng)冷(leng)(leng)(leng)模具(ju)冷(leng)(leng)(leng)冲(chong)压(ya)和(he)热冷(leng)(leng)(leng)模具(ju)冷(leng)(len🌟g)(leng)冲(chong)压(ya)每🌌种体例(li)。这决定于资科的密度、弹塑(su)性、层厚、变形几率标准(zhun)和(he)法(fa)宝就能等，互相(xiang)招(zhao)考虑资科的原本热防范现状和(he)始终(zhong)通过前提条件。
