感溫片彎曲成形工藝及模具設(shè)計
摘要
本設(shè)計題目為感溫片沖壓成形工藝與模具設(shè)計，體現(xiàn)了板類沖壓零件的設(shè)計要求、內(nèi)容及方向，有一定的設(shè)計意義。通過對該零件模具的設(shè)計，進一步加強了設(shè)計者沖壓模具設(shè)計的基礎(chǔ)知識，為設(shè)計更復(fù)雜的沖壓模具做好了鋪墊并吸取了更深刻的經(jīng)驗。
本設(shè)計運用沖壓成型工藝及模具設(shè)計的基礎(chǔ)知識，首先分析了工件的成形工藝及模具成形結(jié)構(gòu)對制件質(zhì)量的影響。介紹了感溫片沖壓模具設(shè)計時要注意的要點，通過對制件進行工藝分析，可確定制件的成形加工為兩次工藝成形，即沖裁落料和一次彎曲。從控制制件尺寸精度出發(fā)，對感溫片沖壓模具的各主要尺寸進行了理論計算，以確定各工作零件的尺寸，從模具設(shè)計到零部件的加工工藝以及裝配工藝等進行詳細的闡述，并應(yīng)用CAD進行各重要零件的設(shè)計。
關(guān)鍵詞：沖裁落料；工藝分析；模具零部件的加工工藝。
Bending temperature film forming process and die design
Abstract
The design of the title sheet for thermal forming process and die design, sheet metal stamping embody parts of the design requirements, content and direction of the design of a certain significance. Through the design of the die parts to further enhance the design of a stamping die designers the basic knowledge for the design of more complex stamping die to do a good job of paving the way and draw a more profound experience.
The design of the use of punch forming process and die design of the basic knowledge, the first analysis of the shape of the workpiece forming process and die structure of the parts quality. Introduced a temperature-chip stamping die design of the main points of attention should be paid through the process of parts for analysis, we can identify parts of the forming process for forming the two, that is, a blanking blanking and bending. Size precision parts from the control, the temperature of the mold sheet size of all the major theoretical calculations carried out to determine the size of the working parts, the parts from the mold design process and the assembly process in detail, etc., and Application of CAD for the design of the important parts.
Keywords: Blanking Blanking; process analysis; mold parts processing.
