落料冲孔弯曲级进模设计
摘要
此次设计为冲孔—落料—弯曲级进模,设计本模具充分利用了网上资源,图书馆藏书,更重要的是老师的谆谆教导,才成就了此模具。
在模具的设计过程中,首先,简要地概述了冲压模具在社会发展领域中的作用及其以后的发展前途。点明了模具的设计意义。然后进行工件的工艺分析,进而确定了工艺方案。计算出了模具工作部分的尺寸公差,设计出零部件,然后依据设计要求选择各个标准件。最后设计出模具的总装配图。在设计过程中需要计算冲压力,落料力,弯曲力及推件力,卸料力。从而判断模具各部件是否能承受压力机的作用。更重要的是模具工作零件的设计,以此为核心的问题,工作零件的误差将直接影响制件的质量。最后利于绘图工具AutoCAD制作了装配图和零件图,而节省了许多时间。
通过此次设计使我不仅掌握了冲压模具设计的一般流程,更好的学习好多在课本上没有学习的知识。

Blunt bore-fall to anticipate-flection the class enters the molding tool
Abstract
This time design for blunt bore-fall to anticipate-flection the class enters the mold,the designwas originallythe molding tool to make use of the on-line resourceswell,the librarylibrary,the more important teacher earnestlyinstruct,just achieving this molding tool.
In the design process of the molding tool,first,the synopsis ground says to hurtle to press the molding tool all after societydevelop the function in the realm and it of development prospect.Order the design meaning of understand the molding tool.Then carryon the craft analysis of thework piece,then made sure the craft projectpute the molding toolwork part of size business trip,designzero partses of,then request to choose the each standard piece according to the design.Design a total assemble diagram of molding tool finally.The demand computes the blunt pressure in design process,falling to anticipate the dint,the flection dint and push a dint,unload to anticipate the dint.Thus judgewhether each parts of molding tool can bear the function of the pressure machine or not.The design of the more important molding toolwork spare parts,with this for core of problem,work spare parts of error marginwill affect the quantityof make the piece directly.Finallythe benefit manufactures to assemble the diagram and the spare parts diagrams in the painting tool AutoCAD,but saved manytime.
Pass this time design make me not onlycontroled to hurtle the general process of press the molding tool design,the better studyis a lot of in the lesson originallyup have no knowledge of study.
