1、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

2、 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 v

The dies here discussed can be eas

CAD and CAM are widely applied in mould design and mould making. CAD allows you to draw a model on screen, then view it from every angle using 3-D animation and

8、, finally, to test it by introducing various parameters into the digital simulation models(pressure, temperature, impact, etc.) CAM, on the other hand, allows you to control the manufacturing quality. The advantages of these computer technologies are legion: shorter design times(modifications can be

9、 made at the speed of the computer),lower cost, faster manufacturing, etc. This new approach also allows shorter production runs, and to make last-minute changes to the mould for a particular part. Finally, also, these new processes can be used to make complex parts. Computer-Aided Design(CAD)of

10、Mould Traditionally, the creation of drawings of mould tools has been a time-consuming task that is not part of the creative process. Drawings are an organizational necessity rather than a desired part of the process. Computer-Aided Design(CAD) means using the computer and peripheral devi

11、ces to simplify and enhance the design process .CAD systems offer an efficient means of design, and can be used to create inspection programs when used in conjunction with coordinate measuring machines and other inspection equipment .CAD data also can play a critical role in selecting process seque

12、nce. A CAD system consists of three basic components: hardware, software, users. The hardware components of a typical CAD system include a processor, a system display, a keyboard, a digitizer, and a plotter. The software component of a CAD system consists of the programs which allow it to perform

13、 design and drafting functions. The user is the tool designer who uses the hardware and software to perform the design process. Based on the 3-D data of the product, the core and cavity have to be designed first. Usually the designer begins with a preliminary part design, which means the work aro

14、und the core and the cavity could change. Modern CAD systems can support this with calculating a split line for a defined draft direction, splitting the part in the core and cavity side and generating the run-off or shut-off surfaces. After the calculation of the optimal draft of the part, the posit

15、ion and direction of the cavity, slides and inserts have to be defined .Then in the conceptual stage, the positions and the geometry of the mould components---such as slides, ejection system, etc.----are roughly defined. With this information, the size and thickness of the plates can be defined and

16、the corresponding standard mould can be chosen from the standard catalog. If no standard mould fits these needs, the standard mould that comes nearest to the requirements is chosen and changed accordingly---by adjusting the constraints and parameters so that any number of plates with any size can be

17、 used in the mould. Detailing the functional components and adding the standard components complete the mould(Fig.23.1).This all happens in 3-D. Moreover, the mould system provides functions for the checking, modifying and detailing of the part .Already in this early stage, drawings and bill of mate

18、rials can be created automatically. Through the use of 3-D and the intelligence of the mould design system, typical 2-D mistakes---such as a collision between cooling and components/cavities or the wrong position of a hole---can be eliminated at the beginning. At any stage a bill of materials and

19、 drawings can be created---allowing the material to be ordered on time and always having an actual document to discuss with the customer or a bid for a mould base manufacturer. The use of a special 3-D mould design system can shorten development cycles, improve mould quality, enhance teamwork and

20、 free the designer from tedious routine work. The economical success, however, is highly dependent upon the organization of the workflow. The development cycles can be shortened only when organizational and personnel measures are taken. The part design, mould design, electric design and mould manufa

21、cturing departments have no consistently work together in a tight relationship. Computer-Aided Manufacturing(CAM)of Mould One way to reduce the cost of manufacturing and reduce lead-time is by setting up a manufacturing system that uses equipment and personnel to their fullest potential. The f

22、oundation for this type of manufacturing system is the use of CAD data to help in making key process decisions that ultimately improve machining precision and reduce non-productive time. This is called as computer -aided manufacturing (CAM).The objective of CAM is to produce, if possible, sections o

23、f a mould without intermediate steps by initiating machining operations from the computer workstation. With a good CAM system , automation does not just occur within individual features. Automation of machining processes also occurs between all of the features that make up a part, resulting in too

24、l-path optimization. As you create features ,the CAM system constructs a process plan for you .Operations are ordered based on a system analysis to reduce tool changes and the number of tools used. On the CAM side, the trend is toward newer technologies and processes such as milling to support th

25、e manufacturing of high-precision injection moulds with 3-D structures and high surface qualities. CAM software will continue to add to the depth and breadth of the machining intelligence inherent in the software until the CNC programming process becomes completely automatic. This is especially true

26、 for advanced multifunction machine tools that require a more flexible combination of machining operations. CAM software will continue to automate more and more of manufacturings redundant work that can be handled faster and more accurately by computers , while retaining the control that machinists

27、need. With the emphasis in the mould making industry today on producing moulds in the most efficient manner while still maintaining quality, moludmakers need to keep up with the latest software technologies-packages that will allow them to program and cut complex moulds quickly so that mould prod

28、uction time can be reduced. In a nutshell, the industry is moving toward improving the quality of data exchange between CAD and CAM as well as CAM to the CNC, and CAM software is becoming more "intelligent" as it relates to machining processes_ resulting in reduction in both cycle time and overall

29、machining time. Five-axis machining also is emerging as a "must-have" on the shop floor-especially when dealing with deep cavities. And with the introduction of electronic data processing(EDP)into the mould making industry, new opportunities have arisen in mould-making to shorten production tim

30、e, improve cost efficiencies and higher quality. 沖壓模具已廣泛應(yīng)用于工業(yè)，在傳統(tǒng)的工業(yè)生產(chǎn)，工人工作很辛苦，有太多的工作，所以效率是很低.在科學(xué)和技術(shù)的今天，使用的沖壓模具開發(fā)在實業(yè)生產(chǎn)獲得更多的關(guān)注，并在工業(yè)生產(chǎn)中越來越被關(guān)注.沖壓模具用飼料技術(shù)也可用于生產(chǎn)，沖壓模具可提高生產(chǎn)的有效性，可以減輕工作負(fù)擔(dān)，因此在科技進(jìn)步和經(jīng)濟價值具有重要意義。 本文主要討論了分類，特征以及技術(shù)的發(fā)展方向。闡述了沖壓零件的形成原理，基本結(jié)構(gòu)和死亡過程的速度和設(shè)計的原則，設(shè)計了一些傳統(tǒng)的沖壓模具：對大直徑管這三個方向解決了傳統(tǒng)的機械加工，拉絲模及沖
