设计简介
摘要
本设计题目为底座垫板的冲孔模具设计，体现了典型冲孔模具设计的要求，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。
该模具为单工序冲孔模。但是在一次冲裁时，孔特别的多，冲裁力也非常的大，为了降低冲裁力，采用阶梯冲裁。
关键词: 冲孔模.凸模.凹模
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.
That die is a single work preface piercing die.But while hurtling to cut once, the bore is special many, hurtle to cut dint also very big, for lowering to blank pressure, adopt stairs to hurtle to cut.
Keywords: The piercing die . punch . cavitydie
