2、ctThis article introduces is the angle iron support punch holes bending concatenation-mould membrane. This mold example structure is simple. The easy to operate is reliable. First launches the size according to the work piece graphic calculation work piece. Again acts according t
3、o launches the size to calculate this components the center of pressure. Material use factor, flowered row of specimen map; Next basis convex-concave mold different manufacture method and the blanking craft plan calculates the convex-concave cutting edge size,computation ramming
4、strength,choice ramming equipment. According to components geometry shape request and size analysis, carries on the convex-concave mold structural design; finally system design. After all parameters calculate, to mold assembly plan, carry on the analysis to the major parts design
5、 and the matching requirement. In design process besides design instruction booklet, also includes the mold the assembly drawing,non-standard letter detail drawing.Keywords:bending, concatenation-mould, pressing前 言 改革开放以来,随着国民经济的高速发展,工业产品的品种和数量的不断增加,更新换代的不断加快,在现代制造业中,企业的生产一方
