U型弯曲冲压成形工艺及模具设计
摘要
本文介绍的是弯板支架冲孔弯曲级进模，该模具实例结构简单实用，使用方便可靠。首先根据工件图算工件的展开尺寸，再根据展开尺寸算该零件的压力中心，材料利用率，画排样图；其次依据凸、凹模不同的制造方法和冲裁工艺方案计算出凸、凹模的刃口尺寸；计算冲压力，选择冲压设备；根据零件的几何形状要求和尺寸的分析，进行凸、凹模结构设计,最后总体设计。当所有的参数计算完后，对模具的装配方案，对主要零件的设计和装配要求技术要求都进行分析。在设计过程中除了设计说明书外，还包括模具的装配图，非标准零件的零件图。

Abstract
This article introduces is the angle iron support punch holes bending concatenation-mould membrane.This mold example structure is simple.The easyto operate is reliable.First launches the size according to thework piece graphic calculationwork piece.Again acts according to launches the size to calculate this components the center of pressure.Material use factor,flowered rowof specimen map; Next basis convex-concave mold different manufacture method and the blanking craft plan calculates the convex-concave cutting edge size,computation ramming strength,choice ramming equipment.According to components geometryshape request and size analysis,carries on the convex-concave mold structural design; finallysystem design.After all parameters calculate,to mold assemblyplan,carryon the analysis to the major parts design and the matching requirement.In design process besides design instruction booklet,also includes the mold the assemblydrawing,non-standard letter detail drawing.
