沖孔—落料復(fù)合模
摘要
我所學(xué)習(xí)的專業(yè)是模具設(shè)計(jì)與制造，這次的畢業(yè)設(shè)計(jì)沖孔－落料復(fù)合模的設(shè)計(jì)是我結(jié)合大學(xué)三年來(lái)所學(xué)習(xí)的專業(yè)知識(shí)和CAD軟件所設(shè)計(jì)出的一套沖壓模具。
本文首先簡(jiǎn)要的概述了沖壓模具在社會(huì)發(fā)展領(lǐng)域中的作用及其以后的發(fā)展方向，點(diǎn)明了模具設(shè)計(jì)的重要意義。然后依據(jù)工件圖進(jìn)行了工藝性分析，進(jìn)而確定了設(shè)計(jì)方案，計(jì)算出了模具工作部分的尺寸，設(shè)計(jì)出工作零部件；然后依據(jù)設(shè)計(jì)要求選擇出各個(gè)標(biāo)準(zhǔn)零部件，最后設(shè)計(jì)出了模具的總裝配圖。在設(shè)計(jì)中，最重要的就是設(shè)計(jì)方案的確定、坯料的計(jì)算和工作零部件的設(shè)計(jì)，這是設(shè)計(jì)的關(guān)鍵，這些設(shè)計(jì)的正確與否直接關(guān)系到設(shè)計(jì)成本的高低及設(shè)計(jì)的模具能否正常工作；在設(shè)計(jì)的最后，總結(jié)了自己在設(shè)計(jì)過(guò)程中的心得和體會(huì)，并對(duì)我的指導(dǎo)老師進(jìn)行致謝。
關(guān)鍵詞：模具設(shè)計(jì)與制造、CAD軟件、工藝性分析、復(fù)合模。
The punch holes - fall the material superposable die
Abstract
I was learning the professional design and manufacture molds, A set of ramming mold which this time graduation project punch holes - fall the material superposable die the design are I unify which the university for three years to study the specialized knowledge and the CAD software design.
The first brief outlines ram heads in the field of social development and its role in the future development direction, point out die design significance. Then, based on her analysis of the processes leading to the design of the programme, calculated the size of the instrument work, design work components;Then choose on the basis of various criteria for the design of parts and components, the final design of the layout of the total assembly maps. In the design, the most important thing is to design programmes to identify, semifinished materials and spare parts for the design, which is the key to the design of the design correct or not is directly related to the high cost of design and layout design can be normal; In the final design, summed up his experience in the design process and experience, and I thank guidance teachers.
Key words : die design and manufacturing、 CAD software、 analytical techniques、Superposable die.
