风罩成形工艺及模具设计
摘要：冷冲压加工在我国已有很长的历史，封建社会时期我国劳动人民纯手工打造金、银和铜饰品，制作各种日用品，就已显示出精巧的工艺技术，但那时人们劳动强度大，制作时间长，不宜生产大量的生活用品供生活所需，随着现今科技的进步，工业发展，模具在工业生产中引起了人们的重视。冲压模具生产产品效率高，能保证工件的精度，实现了自动化，适合大批量生产。未来模具将向全面推广CAD/CAE/CAM,模具优质材料及表面处理技术，特种加工，模具扫描及数字化系统，模具研磨抛光将自动化、智能化，模具自动加工系统方向发展。
本设计是对风罩的落料、冲孔、切边的设计，完成的内容为：对模具在工业生产中的作用，模具发展历史与现状，未来模具的发展前景做了概述。进行零件的形状、尺寸、精度工艺分析，确定合理的工艺方案，确定工序数目。确定拉深凸、凹模间隙，计算落料、冲孔的凸、凹模刃口尺寸。确定凸、凹模结构，并绘制零件图，设计定位零件，压料、卸料、出件零部件，设计固定零件，选择模架标注紧固件，最后绘制模具非标准零件图。
本设计运用模具使钢料产生塑性变形，获得最终需要的零件，这是一种少切削、无切削、多工序重合的生产方法，并且生产零件，提高了生产效率，对相似工件的大批量生产具有参考的作用。

Thewind cover forming technologyand die design
Abstract：Cold stamping has a long historyin China.The period of feudal society,ourworking people handmade gold,silver and copper jewelry,production of dailynecessities,Alreadyshows a sophisticated technology,But then the people to the labor intensityof production a long time,should not produce large amounts of dailynecessities for living expenses.With today's advances in technology,industrial development,attracted the attention of people die in industrial production.Stamping mold products,high efficiency,to ensure the precision of theworkpiece,automated,suitable for mass production.The moldwill comprehensivelypromote the automation of CAD/CAE/CAM,mold-qualitymaterials and surface treatment techniques,special machining,mold scanning and digitizing systems,mold grinding polishing,intelligent,mold automatic processing system direction.
This design is towind a cover the design of the blanking,punching and trimming,to complete the content as follows: to die in the role of industrial production,mold development historyand present situation,future development prospects of the overviewof the mouldponents of the shape,size,precision process analysis,to determine the reasonable processing plan,determine the number of process.Determine the drawing convexand concave die clearance,calculation of blanking,punching convexand concave die cutting edge dimension.Determine the convexand concave die structure,and drawthe part drawing,design positioning parts,pressure,discharge,the components,design of fixed parts,choose to die setwith fasteners,the final map die non-standard parts.
The use of design mold steel material of the plastic deformation,to obtain the final parts,this is a little cutting,cutting,process production methods overlap,and progressive die production parts,improve production efficiency,similar to theworkpiece high-volume productionwith reference to the role.
