设计简介
支板冲压成形工艺及模具设计
摘 要：本设计题目为复合模具设计，体现了典型复合模具设计的要求，内容与方向。通过工艺分析，工艺方案的确定，确定了模具设计的方向，对毛坯尺寸的确定，计算冲裁力，来计算压力中心，选择压力机和压力机的吨位。
本设计运用了冲裁工艺及模具设计的基础知识。首先，分析了板材的性能要求，为选去模具的类型做了准备，同时，也为凸，凹模的材料有了依据。后分析冲裁件的特征，确定了模具设计参数，选择其他零件及卸料装置。也为凸，凹模尺寸的计算有了根据。还有零件的加工工艺。
本设计运用冲压成形工艺及模具设计的基础知识，首先分析了冲裁件的冲压工艺性，为确定冲裁工艺方案做好了准备；然后计算冲裁力和模具刃口尺寸，便于选取压力机及确定工作零件的尺寸和结构；最后分析了制件的特征，确定模具的设计参数、设计要点及推件装置的选取。
本冲裁件上孔为规则形状的孔,为了便于冲孔凸模的加工，在设计时把冲孔凸模设计成台阶式。为了方便制件的取出，本副模具采用倒装结构形式,同时,为了简化模具结构采用弹性推件装置。

The pressworking forming process and mold design of protrude board
Abstract：This design topic designs for The piercing die design of the dunnage backup plate, body now typical model The piercing die design of request, contents and direction.Pass the craft analysis, the craft project really settles, making sure the direction of The piercing die design, really settling to the blank product size, computing to the blanking pressure, compute the pressure center, choose the tonnage of the pressure machine and the pressure machine.
This design made use of to hurtle foundation knowledge of blanking craft and The piercing die design. First, Analyzed the function request of the plank material, did preparation for the type that chooses to the die, is also convex, in the meantime, the material of punch and cavitydie had a basis.Analyze to hurtle a characteristic of cut the piece behind, make sure the molding tool design parameter, choose other spare partses and unload to anticipate device.Is also convex, the calculation of the cave mold size had a basis.Still there is spare parts to process a craft.
The use of the design process and die stamping forming the basis of design knowledge and analysis of the first blanking of the stamping process, to determine blanking of the programme prepared for and then calculating punching power and size Die Cutting Edge, For selected press and determine the size and structure of parts of the last parts of the characteristics of the design parameters established mold, design features and pushing the select pieces of equipment.
Blanking of the rules on the shape of the hole, in order to facilitate the processing punch punching, punching in the design of the punch designed as a step processing. To facilitate the removal of parts, the Vice-use flip-die structure, at the same time, in order to simplify the structure adopt a flexible mold push pieces of equipment.
