1、手啤机(人工操作在压力机)，5吨，8吨，10吨，16吨，25吨，35吨，40吨，63吨，80吨， 100吨，120吨，160吨，200吨，等等。这只是普通的按吨位的分类。还有是按普通型 的或国标型的 或者是定做的专机，这都是有区别的。如果按功能上分又可分为：深虎口式，普通可倾式，拉深用(超 大行程)式，液压冲床，等等，冲床冲压力计算公司 p=kit r其中:k为系数，一般约等于1,i冲压后产品的周长 岸位mm; t为材料厚度 岸位mm;r为材料抗剪强度.单位MPa .算出的结果是单位是牛顿，在把结果除以9800N/T,得到的结果就是数字是多少就是多少T.这个只能算 大致的，为了安全起见，把以上
2、得到的值乘以2就可以了，这样算出的值也符合复合模的冲压力指外力与材料轴线垂直，并对材料呈剪切作用时的强度极限1入3抗剪强度为：261 274MPa或26.628Kgf/mm245# 抗剪强度为：411MPa 或 42Kgf/mm2计算公式：抗剪强度=06 0.8抗拉强度冲裁力计算公式：P=K*L*t*TP -平刃口冲裁力(N);t材料厚度(mm);L冲裁周长(mm);t -材料抗剪强度(MPa);K 安全系数，一般取K=1.3.冲剪力计算公式：F=S*L*440/10000S -工件厚度L -工件长度一般情况下用此公式即可。冲压力是指在冲裁时，压力机应具有的最小压力。P冲压=?冲裁+P卸料+P
