轴碗的冲压工艺及模具设计【落料拉深冲孔翻孔复合模】
摘要：本课题是对轴碗落料拉深冲孔翻孔复合模模具设计，其中分别对模具的工作零部件等六大类零部件作详细设计。设计的主要内容包括冲裁件的工艺分析及工艺方案的确定、工艺计算、冲裁模具的设计、模具的安装与调整等。
在工艺计算部分要对排样设计与计算、冲压力的计算、模具压力中心的确定、凸凹模尺寸并确定制造公差的计算与计算等内容详细计算。
在冲裁模的设计部分要对工作零件、定位零件、卸料与顶件零件、导向零件连接与固定零件等结构进行详细的分析设计。要在设计过程中了解模具的工作过程和注意标准的选用，对复合冲裁模的结构有进一步的了解。
模具的安装与调试部分要注意导柱模具与无导柱模具的安装方法及顺序，通过模具的安装，了解模具的组成及各部分零部件的作用等。注意模具安装过后的试冲过程中常见的缺陷与解决方法等。
通过这次设计要对复合模具有更进一步的了解，在设计时要注意模具结构简单、模具使用方便、模具寿命高等问题。并且要提高生产效率，保证产品的质量。

Abstract:This lesson a molding tool for is fall to anticipate to pull to the stalk bowl deep blunt the bore turn over bore compound mold molding tool design,among them distinguish towait to theworkzero parts of the molding tool six the parts of bigzeros make the detailed design.The main contents of designing includes towash to cut a piece craft analysis and craft projects really settle, craft calculation, the gearing of the design, molding tool thatwash to cut the molding tool and adjust etc..
Compute in the craft the partwant to be to the row kind design and calculation,wash the calculation, molding tool pressure of the pressure center to really settle, convex and cave mold size and make sure the calculation that make the business trip and compute the detailed calculation in contents in etc..
Cut the mold towant at the design part thatwash to thework spare parts, position the spare parts and unload to anticipatewith a spare parts, lead to spare parts conjunctionwith fix spare parts etc. construction the proceeding the detailed analysis design.Want to be in design processwork process of understanding the molding toolwith notice to choose to use standardly, to reunite the construction thatwash the understanding that cut the mold further have.
The gearing of the molding toolwith adjust to try the partwant to notice to lead the pillar molding tool to lead the pillar molding toolwith gearing method and sequences that have nos, passing the gearing of the molding tool, understanding the molding tool constitute and function etc. of each parts of the parts ofzeros.Noticing the molding tool installs to try towash the familiar blemish of inside of process later on and solution method etc..
Pass this time graduate the designwant to have the nearer and one-step understanding to the compound molding tool,while designing to notice the molding tool construction simple, molding tool usage convenience, high etc. in life span in molding tool problem.And increase production efficiency, guarantee the quantity of the product.
