底座沖壓成形工藝及模具設(shè)計(jì) 摘要：本設(shè)計(jì)題目為底座沖孔落料模設(shè)計(jì)。通過對該零件模具的設(shè)計(jì)，進(jìn)一步加強(qiáng)了設(shè)計(jì)者沖壓模設(shè)計(jì)的基礎(chǔ)知識，為設(shè)計(jì)更復(fù)雜的沖壓模具做好了鋪墊和吸取了更深刻的經(jīng)驗(yàn)。本設(shè)計(jì)運(yùn)用沖壓成型工藝及模具設(shè)計(jì)的基礎(chǔ)知識，介紹了模具設(shè)計(jì)時(shí)要注意的要點(diǎn)，并較多的考慮了模具結(jié)構(gòu)的調(diào)整性、易更換性及模具成本。從控制制件尺寸精度出發(fā)，對底座沖孔落料模的各主要尺寸進(jìn)行了理論計(jì)算，以確定各工作零件的尺寸，從模具設(shè)計(jì)到零部件的加工工藝以及裝配工藝等進(jìn)行詳細(xì)的闡述，并應(yīng)用 CAD 進(jìn)行各重要零件的設(shè)計(jì)。關(guān)鍵詞：沖壓模 工藝分析 模具結(jié)構(gòu) Base in the beam blanking die design Abstract:The topic for the design of the former Liang punching blanking die design. The designer’s foundation knowledge is reinforced and is able to design more complex press die through the design. The critical points of die for stamping design are introduced, and the adjustable character of die structure,exchange character as well as the die costs are all considered farther. Starting from controlling dimensional accuracy, the carry the cover to the main dimensions of stamping die are carried out so as to determine the size of different parts, the die design and the process of parts as well as assembling process and etc of stamping die are stated in details.Key words: stamping die process analysis die structure
