摘 要
在目前激烈的市場競爭中，產(chǎn)品投入市場的遲早往往是成敗的關(guān)鍵。用模具生產(chǎn)所表現(xiàn)出來的高精度、高復(fù)雜程度、高一致性、高生產(chǎn)率和低消耗，是其他加工方法所不能比擬的。因此客戶對模具開發(fā)周期要求越來越短，不少客戶把模具的交貨期放在第一位置，然后才是質(zhì)量和價格。因此，如何在保證質(zhì)量、控制成本的前提下加工模具是值得認真考慮的問題。模具加工工藝是一項先進的制造工藝，已成為重要發(fā)展方向，在航空航天、汽車、機械等各行業(yè)得到越來越廣泛的應(yīng)用。模具加工技術(shù)，可以提高制造業(yè)的綜合效益和競爭力。研究和建立模具工藝數(shù)據(jù)庫，為生產(chǎn)企業(yè)提供迫切需要的高速切削加工數(shù)據(jù)，對推廣高速切削加工技術(shù)具有非常重要的意義。
本次畢業(yè)設(shè)計就是在SolidWorks軟件平臺上對電動機定子鐵芯沖槽模具設(shè)計及動畫演示。在設(shè)計過程中，通過了解和掌握沖壓模具的材料及定子鐵芯沖槽模具設(shè)計的有關(guān)知識，主要完成了模具的工作零件、定位零件、導(dǎo)向零件和裝配體的設(shè)計，并利用SolidWorks軟件進行三維造型及工作過程的動畫設(shè)計。
本沖壓模具采用的是冷沖壓，冷沖壓是一種先進的金屬加工方法，與其它加工方法比較，有很多優(yōu)點。在壓床簡單沖壓下，能得到形狀復(fù)雜的零件；制得的零件一般不需進一步加工，可直接用來裝配，而且有—定精度，具有互換性；在耗料不大的情況下，能得到強度高、足夠剛性而重量輕、外表光滑美觀的零件；材料利用率高，生產(chǎn)率高，便于實現(xiàn)機械化和自動化；操作方便，要求的工人技術(shù)等級不高，便于組織生產(chǎn)；在大量生產(chǎn)的條件下，產(chǎn)品的成本低。冷沖壓模具也有缺點，缺點是模具要求高、制造復(fù)雜、周期長、制造費昂貴，因而在小批量生產(chǎn)中受到限制。另外，沖壓件的精度決定于模具精度。如零件的精度要求過高、用冷沖壓生產(chǎn)就難以達到。

Abstract
In the current fierce competition in the market, the product to market sooner or later, is often the key to success. Shown with the mold high-precision, high complexity, high consistency, high productivity and low consumption, other processing methods can not match. Therefore, customers increasingly demanding shorter development cycle mold, many customers come first delivery set the mold, then is the quality and price. Therefore, how to ensure quality, cost control, under the premise processing mold is worthy of serious consideration. Mold processing technology is an advanced manufacturing technology, has become an important direction of development in the aerospace, automotive, machinery and other industries are more widely used. Mold processing technology, can improve the overall efficiency of the manufacturing sector and competitiveness. Research and the establishment of the mold process database, provide urgently needed for the production of high-speed machining data, the promotion of high-speed machining technology is of great significance.
The graduation project is in the SolidWorks software platform of the motor stator core slot punch die design and animation. In the design process, stamping dies by understanding and mastering the material and the stator core slot punch die design knowledge, the main working parts to complete the mold, positioning parts, steering parts and assembly design, and using SolidWorks software for three-dimensional Work process modeling and animation design.
The stamping die is used in cold stamping, cold stamping is an advanced metal processing methods, compared with other processing methods, has many advantages. In simple stamping presses, the parts of complex shape can be; parts generally obtained without further processing, can be directly used for assembly, but also - given precision, with interchangeability; in feed consumption is not the case, Can get high strength, sufficient rigidity and light weight, smooth and beautiful appearance of the parts; materials, high efficiency, high productivity, ease of mechanization and automation; easy to operate, requires low technical level of workers, facilitate organization of production; in the mass production Conditions, products, and low cost. Cold stamping die has its drawbacks, the disadvantage is demanding mold, manufacture of complex, long period, high manufacturing costs, and thus is limited in small batch production. In addition, the precision stamping precision depends on the mold. Such as high precision parts, cold stamping production difficult to achieve.
