Abstract
Punching die has been widely used in industrial production.In the traditional industrial production,the worker work very hard,and there are too much work,so the efficiency is low.With the development of the science and technology nowadays,the use of punching die in the industial production gain more attention,and be used in the industrial production more and more.Self-acting feed technology of punching die is also used in production,punching die could increase the efficience of production and could alleviate the work burden,so it has significant meaning in technologic progress and economic value.
The article mainly discussed the classification,feature and the developmental direction of the pnnching technology.Elaborated the punching components formation principle,the basic dies structure and the rate process and the principle of design; and designed some conventional punching die:the die for big diameter three direction pipe which solved the problom of traditional machining,the drawing and punching compound die with float punch-matrix,the drawing and cutting compound dies with unaltered press,the compound die for the back bowl of the noise keeper,the design of the compound die which could produce two workpieces in one punching,the bending die for the ring shape part ,the bending die which used the gemel ,automate loading die for cutting,the drawing,punching and burring compound dies with sliding automated loading,the punching die for the long pipe with two row of hole,the drawing die for the square box shape workpiece and the burring die for the box shape workpiece.The punching dies that utilized the feature of the normal punch shaped the workpiece in the room temperature,and its efficiency and economic situation is excellent.
The dies here discussed can be easily made,conveniently used,and safely operated.And it could be used as the reference in the large scale production of similar workpieces.
Key word:punching,die,machincal,manufacture,die design,punching,bending,drawing
摘 要
冲压模具在实际工业生产中应用广泛。在传统的工业生产中,工人生产的劳动强度大、劳动量大,严重影响生产效率的提高。随着当今科技的发展, 工业生产中模具的使用已经越来越引起人们的重视,而被大量应用到工业生产中来。冲压模具的自动送料技术也投入到实际的生产中,冲压模具可以大大的提高劳动生产效率,减轻工人负担,具有重要的技术进步意义和经济价值。
本文主要对冷冲压技术的分类、特点及发展方向作了讨论;论述了冲压零件的形成原理、基本模具结构与运动过程及其设计原理;对典型的冲压件模具进行了设计:大直径三通管冲压复合模设计解决了大直径三通管的加工难题、带有浮动凸凹模的拉伸冲孔复合模设计、适力压边式落料拉伸切边复合模设计、消音器后补碗落料、拉深、冲孔、翻边复合模设计、一模两件落料拉伸冲孔翻边复合模设计、环形弯曲件的模具设计、铰链卷圆成形工艺及模具设计、半自动送料切角装置设计、滑板式送料拉深、冲孔、翻边模设计实现自动送料、长管多孔冲模设计、带凸缘台阶方盒形零件拉深模和盒形件侧壁小孔翻孔模。冲压模具的设计充分利用了机械压力机的功用特点,在室温的条件下对坯件进行冲压成形,生产效率提高,经济效益显著。
本文介绍的模具实例结构简单实用,使用方便可靠,对类似工件的大批量生产具有一定的参考作用。
