支撑板零件冲压工艺及模具(复合模弯曲模)设计(含CAD零件图装配图)(论文说明书12000字,CAD图纸8张,冲压工艺卡)
摘要：模具是工业生产中使用广泛的基础工艺装备。模具生产制件所表现出来的高精度、高复杂性、高一致性、高生产率和低消耗是其他加工制造方法所不能比拟的。模具技术水平的高低已经成为衡量一个国家制造水平高低的重要标准，并在很大程度上决定着产品的质量、效益和新产品的开发能力。 本设计课题是支撑板零件冲压工艺及模具设计,主要包括落料冲孔复合模及其弯曲模设计。本论文主要阐述了支撑板落料冲孔复合模及其弯曲模的设计步骤过程。
支撑板复合模采用倒装式结构，具有操作方便安全，生产效率高优点。该部分设计包括了对支撑板的冲裁工艺性分析；工件的排样与搭边计算；冲压力及冲压中心的计算；对模具主要零件的设计，如冲裁间隙的选择、凸模、凸凹模和凹模刃口部分尺寸计算，结构尺寸的确定；对模具标准件的选用分析，目前，模具零件大多已经标准化，设计时选用标准件，如模架主要零部件，导柱、导套、上下模座、弹性元件等。根据冲压力的计算进行了压力机的选择。
弯曲模的设计与复合模的设计类似，弯曲模结构上略为简单。这部分设计内容包括支撑板弯曲工艺分析；弯曲力计算；对弯曲后工件弯曲回弹量计算；弯曲模主要零件的设计，即凸模和凹模工作部分尺寸的计算，结构尺寸的设计。对模具标准件的选用分析，如模架主要零部件，导柱、导套、上下模座、垫板、固定板等。

The Design of Support Board Blanking-piercing Compound Dies and Bending Dies
Abstract：Die industrial production is the use of broad-based technology and equipment. Mold parts demonstrated by the high precision and high complexity, high consistency, high productivity and low consumption of other processing methods can not be compared. Die technology has become the level of a country's level of the important manufacturing standards and to a large extent determine the quality, effectiveness and capability to develop new products. The design issue is support plate parts stamping process and die design, including blanking punching and bending die compound die design. This paper described the support plate blanking of punching and bending die-step process of design.
Support plate of a flip-style structure, easy to operate with safe, high-productivity advantage. The design includes some of the support plate blanking of the analysis; parts of the layout and take-calculated and ram-pressure center of the calculation; Die major parts of the design, such as punching gap choice, punch, Tuao Mould and Die edge of the size, structure size to be confirmed; die on the selection of standard parts, at present, most of mold parts have been standardized, the design criteria of selection, such as die-main parts, I.-I. Case, - Block, from top to bottom, flexible components, and so on. According to the calculation-pressure presses a choice.
Bending Die Design and the design of a similar model, slightly bending die on the simple structure. This part of the design include support plate bending process analysis; bending of the calculation; bending after the rebound in terms of bending the workpiece; bending die major parts of the design, that is, punch and die work of the calculation of the size, structure size of the design. Die standard part of the selection of major components such as die-I.-I. Case, from top to bottom-Block, Dianban the fixed plate, and so on.

支撑板冲裁工艺性分析
本设计是一支撑板落料冲孔复合模及弯曲模
生产批量：大批量
材料：45#
材料厚度：2mm
由零件图可知，支撑板的加工涉及到落料、冲孔和弯曲三道工序。该零件形状简单、对称，尺寸不大，是由简单的圆和直线组成，工艺性好。冲裁件的经济精度不高于IT11级，一般要求落料件精度最好低于IT10级，冲孔件最好低于IT9级。支撑板零件的加工精度要求为IT10，能达到经济精度，适合大批量的生产，生产成本经济，经济性好。几何形状，尺寸和精度等情况均符合冲裁的工艺要求。因为零件的加工涉及三道工序，为保证零件的精度要求，故先采用倒装式落料冲孔复合模对工件冲孔落料加工，再利用弯曲模对冲裁后的工件进行弯曲，从而加工出最后的零件。
