guide部位），壓料板之壓料處采突出設(shè)計(jì)以提高局部的壓力使材料受到壓縮應(yīng)力而防止扭曲或反曲現(xiàn)象之發(fā)生。 </p> <p> <br /> </p> <p> ③沖切加工順序 </p> <p> <br /> </p> <p> 適正的沖切加工順序設(shè)計(jì)是改善導(dǎo)腳之沖切變形或扭曲的***方法，欲藉由后續(xù)的退火作業(yè)以矯正導(dǎo)腳之沖切變形或扭曲是難以達(dá)成的。下列是沖切順序考量之基本原則： </p> <p> <br /> </p><p> a. 模具朝小型化 </p> <p> <br /> </p> <p> 由于線割放電加工（WEDM）技術(shù)之發(fā)展使其加工精度及表面品質(zhì)得以提高，因此利用WEDM方式進(jìn)行母模塊或壓料板入塊之加工漸有替代研磨加工之可能，如此可減少?zèng)_壓工程站數(shù)（空站之設(shè)計(jì)可減少）而使模具尺寸大幅縮小。為配合高速?zèng)_床之規(guī)格，多腳數(shù)導(dǎo)線架（100 pins以上）之沖切模具尺寸達(dá)1200 mm以上長(zhǎng)度，故其沖壓生產(chǎn)方式必須采沖床串行布置型。 </p> <p> <br /> </p> <p> b. 模具組件朝小型化及高精度化 </p> <p> <br /> </p> <p> 以多腳數(shù)導(dǎo)線架用導(dǎo)腳沖切沖頭為例，其形狀、尺寸之動(dòng)向朝外形尺寸縮小、刃部長(zhǎng)度減短、沖頭厚度更薄發(fā)展，而其精度動(dòng)向朝高精密、低加工面粗度進(jìn)展。為了達(dá)到如此高精度（尺寸公差±2 μm以下）及低表面粗度（0.3 μm Ra以下）之要求，使用高精度研磨設(shè)備及低表面粗度之線割放電加工機(jī)是必要的。 </p> <p> <br /> 沖頭正在五金沖壓模具傍邊也叫凸模、上模、陽(yáng)模、沖針等,而沖頭又分為A型沖頭、T型沖頭、異型沖頭。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="深圳耐磨精密五金模具廠家,精密五金模具"

工程模又可以分為復(fù)合模、拉伸模、鉚合模等，下面簡(jiǎn)單介紹一下這些模具的結(jié)構(gòu)和作用； </p> <p> <br /> </p> <p> 工程模：也稱為“單工序?！?，是指在沖壓的一次行程中，只能完成一個(gè)沖壓工序的模具。這一工程打完了之后，需要人工或用機(jī)械手把產(chǎn)品從模具里面取出來，然后放到下一站的模具里面繼續(xù)生產(chǎn)，直到模具的***一個(gè)工序打完，整個(gè)產(chǎn)品才算完成。這種模具維修起來簡(jiǎn)單，但生產(chǎn)起來費(fèi)時(shí)費(fèi)力，需要花費(fèi)較多的人工和時(shí)間成本，產(chǎn)品報(bào)廢率較高。 </p> <p> <br /> </p> <p> 復(fù)合模：常見的復(fù)合模具結(jié)構(gòu)有有復(fù)合下料、復(fù)合拉伸等，這種模具結(jié)構(gòu)和別的工程模結(jié)構(gòu)略有不同。其凸模(也稱為公?；驔_頭)設(shè)計(jì)在下模，其它幾塊模板依次是下夾板(固定凸模沖頭)、下止擋板和下脫料板(外脫)，上模依次是母模(或刀口)、內(nèi)脫板和上墊板構(gòu)成，內(nèi)脫使用等高套筒掛在上墊板上面，然后用打桿或彈簧頂著。比如用來下料的復(fù)合模，其內(nèi)脫一般脫出來母模0.50mm即可，不可以低于母模，要不然母模刀口容易崩掉或者不脫料。內(nèi)脫的力量要足夠大，才能把產(chǎn)品從母模里面頂出來，一般如果材料比較厚的話，我們上面裝的是氮?dú)鈴椈伞?</p>
