端蓋拉深復(fù)合模設(shè)計(jì)
摘 要：本設(shè)計(jì)課題介紹了盒形蓋體拉伸擠切復(fù)合模的結(jié)構(gòu)設(shè)計(jì)及工作過程。針對(duì)零件擠切后口部呈尖銳刃口狀現(xiàn)象，改進(jìn)了模具結(jié)構(gòu)，消除部分加工缺陷，分體現(xiàn)了沖壓工藝先進(jìn)性和高效性,有一定的設(shè)計(jì)意義。通過對(duì)工藝零件的工藝分析及模具結(jié)構(gòu)設(shè)計(jì), 鞏固所學(xué)的知識(shí)、熟悉有關(guān)資料,樹立正確的設(shè)計(jì)思路,加強(qiáng)了對(duì)模具的整體認(rèn)識(shí),提高自己的實(shí)際模具設(shè)計(jì)工作能力。
本計(jì)運(yùn)用了沖壓成形模具設(shè)計(jì)的基本知識(shí)，首先對(duì)整個(gè)零件的了解分析工藝參數(shù),沖壓工藝性能,然后確定沖壓模的結(jié)構(gòu)形式，工零部件的設(shè)計(jì)與計(jì)算，拉深和切邊在一個(gè)工序上完成，本副模具優(yōu)點(diǎn)結(jié)構(gòu)簡單緊湊，易于加工維修，缺點(diǎn)取件可能不太方便。

Cover Tensile Trimming Composite Modulus Design Abstract:The design issues on the box-shaped body covered crowded tensile shear modulus of the composite structure design and working process. Against cutting crowded parts after mouth was sharp blade-like phenomenon, improve the structure of the mold and eliminate some processing defects, embodies the nology Analysis and Die of the composite structure Design ,consolidate the knowledge acquired and are familiar with relevant information, establish the cstamping process advanced and efficient.So this design has a certain of significance. Through of the parts of the process Techorrect design ideas, the right to strengthen the overall mold and enhance awareness of their actual ability to mold design.
Total use of the stamping die design of the basic knowledge, the first part of the whole understanding、analysis of process parameters, stamping process performance, and then determine the structure of stamping die form, the design and calculation of the components, Drawing and trimming processes in a complete, the vice die advantages of simple structure compact and easy maintenance processing, shortcomings pick-up may not be convenient.
