摘要
本文是對(duì)尺寸小，精度要求相對(duì)較高，工藝比較復(fù)雜，生產(chǎn)批量大的接觸片進(jìn)行設(shè)計(jì)。在對(duì)接觸片結(jié)構(gòu)工藝性和材料加工工藝性正確分析的基礎(chǔ)上，采用敘述與計(jì)算相結(jié)合的方式，分別對(duì)級(jí)進(jìn)模的沖孔、切口等工序進(jìn)行了從材料的選擇到工作零件、定位零件、卸料零件、導(dǎo)向零件和安裝固定零件等進(jìn)行了設(shè)計(jì)。在所有的工序中，翻邊工序的凸、凹模結(jié)構(gòu)設(shè)計(jì)是難點(diǎn)，本文提出了在級(jí)進(jìn)模的最后一道工序中采用復(fù)合模加工的新思路，討論了思路的可行性，并對(duì)其進(jìn)行了整體和局部的結(jié)構(gòu)設(shè)計(jì)。這種設(shè)計(jì)的思路有著良好的借鑒性。此級(jí)進(jìn)模的設(shè)計(jì)，對(duì)以往的學(xué)習(xí)進(jìn)行了一次綜合性的運(yùn)用，對(duì)今后的工作也有相當(dāng)大的指導(dǎo)意義。
關(guān)鍵詞：級(jí)進(jìn)模、沖孔、切口
ABSTRACT
This paper is the size of small, relatively high precision, the process is more complicated, mass production of electronic components large base unit for deep, piercing and flanging progressive die design..Base unit in the structure of materials and processing sexual correct analysis on the basis of Narration and calculated using a combination of methods, the Progressive Piercing Die incision, Drawing, flanging of the processes from the choice of materials to the design.of work components, positioning components and dump parts, oriented parts and fixed components .In all processes, flanging process convex, concave die is difficult structural design, This paper proposes a progressive die in the final process to a composite scale processing of new ideas and discuss the feasibility of ideas, and on the whole and partial structural design. This design has good ideas from nature. This progressive die design, the study of the past, carried out a comprehensive application, for the future work of a great guiding significance.
Keywords : Progressive Die , flanging, blanking incision
