支撐板沖壓成形工藝及模具設(shè)計(jì)
摘 要:本設(shè)計(jì)課題介紹了彎曲、沖裁復(fù)合模的結(jié)構(gòu)設(shè)計(jì)及工作過(guò)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(guò)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(shù)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，彎曲和切邊在一個(gè)工序上完成，本副模具優(yōu)點(diǎn)結(jié)構(gòu)簡(jiǎn)單緊湊，易于加工維修。

Support plate stamping forming process and die design
Abstract: The design of the subject introducs the curved structure of blanking compound die design and working process. After cutting for parts crowded mouth like the phenomenon of sharp edge, and improve the structure of the mold to eliminate processing defects, sub-stamping process reflects the nature and efficiency, the design of a certain significance. Parts of the process technology and die structure design, the consolidation of knowledge, familiar with the relevant information, establish the correct design to enhance the overall understanding of the mold, to improve their ability to work the actual mold design.
The use of a stamping die design basic knowledge, the first part of understanding the whole analysis process parameters, the performance of stamping process, and then determine the structure of the form of stamping die, the parts of the design and calculation, bending and cutting-edge processes in a completed, the advantages of simple structure, deputy dies compact, easy maintenance processing.
Keywords: Process analysis; Bending; edge; die structure.
