焊片沖孔落料彎曲模設(shè)計
摘 要
本設(shè)計題目為中焊片沖孔落料彎曲模設(shè)計。通過對該零件模具的設(shè)計，進一步加強了設(shè)計者沖孔落料彎曲模設(shè)計的基礎(chǔ)知識，為設(shè)計更復雜的沖壓模具做好了鋪墊和吸取了更深刻的經(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，介紹了模具設(shè)計時要注意的要點，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)，對外殼沖孔切邊模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：沖孔，落料，彎曲模 工藝分析 模具結(jié)構(gòu)
The design of punching，bending and blanking die of Soldering Flake
Abstract
The design the topic for the Design of the Trimming Die punching shell. The designer’s foundation knowledge is reinforced and is able to design more complex press die through the design.
The design of the use of punch forming process and die design of the basic knowledge on the mold design to the main points of attention and more consideration of the mold structure, and easy to replace and the cost of mold. Size precision parts from the control point on the shell punching die trimming the 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 the application of CAD for the design of the important parts.
Key words: Punch holes, Falls the material ，Bending die， process analysis , die structure
