鈑金設(shè)計(jì)小知識（一）鈑金設(shè)計(jì)小知識（二）彎曲件的孔邊距離：a)、先沖孔再折彎：彎曲有孔的毛坯時(shí)，如果孔位于彎曲區(qū)附近，則在彎曲時(shí)孔的形狀會發(fā)生變形，為了避免這種缺點(diǎn)的出現(xiàn)，必須使這些孔分布在變形區(qū)域之外(圖8)，從孔邊到彎曲半徑r中心的距離取為：當(dāng)t＜2mm時(shí)，L≥t；當(dāng)t≥2mm時(shí)，L≥2t。如果是螺紋孔或有裝配要求的光孔，而距離沒有達(dá)到上述要求，則螺紋須在折彎完成后加工，否則螺紋會因拉伸變形而失效。b)、先折彎再沖孔：在彎曲件或拉延件上沖孔時(shí)，其孔壁與工件直壁之間應(yīng)保持一定的距離)，距離太小時(shí)，在沖孔時(shí)會使凸模受水平推力而折斷：從孔邊到彎曲半徑r中心的距離取為：L≥。圖9彎曲件的尺寸精度彎曲件的尺寸，由于影響因素較多，一般不屬配合的尺寸，其精度取10級公差***值的一半并冠以“±”號，但**小精度偏差不得小于表6中所列的直線尺寸公差值和角度公差值，如超過表列數(shù)值必須在彎曲后進(jìn)行手工校正。表6彎曲件的尺寸材料厚度t尺寸B尺寸A（毫米）≤18>18~30>30~50>50~80>80~120>120~180>180~260>260~360>360~500毫米尺寸A精度等級(GB)≤1≤1008>100~2008>200~4008>400~7009>1~3≤1008>100~2008>。鈑金設(shè)計(jì)都需要注意哪些問題？</p><div

3、折彎方向鈑金折彎時(shí)應(yīng)盡量垂直于金屬材料纖維方向。當(dāng)鈑金折彎平行于金屬材料纖維方向時(shí),在鈑金折彎處很容易產(chǎn)生裂紋,折彎強(qiáng)度較低,易破裂,如圖所示。4、壓死邊壓死邊的死邊長度與材料的厚度有關(guān)。如圖所示，一般死邊**小長度L≥4t+R。壓死邊一般適用于板材為不銹鋼、鍍鋅板、覆鋁鋅板等，電鍍件不宜采用，因?yàn)閴核肋叺牡胤綍袏A酸液的現(xiàn)象。5、180度折彎**小折彎邊尺寸L為表19彎曲件L型折彎高度極限值，高度H應(yīng)該選擇表1公司常用鈑金外協(xié)板材匯總。6、避免因折彎根部不能壓料而造成折彎失敗鈑金折彎時(shí),常因?yàn)槠渌卣骶嚯x鈑金折彎根部距離太近,造成不能壓料而無法折彎或者折彎嚴(yán)重變形。（1）在鈑金折彎根部上方至少需要保證2倍鈑金厚度加上折彎半徑的距離上沒有其他特征阻擋鈑金折彎時(shí)的壓料。圖中所示原始的設(shè)計(jì)中,壓死邊后太靠近鈑金折彎根部,造成鈑金折彎時(shí)不能壓料而折彎失敗。（2）鈑金抽牙太靠近折彎根部而造成折彎無法進(jìn)行，此時(shí)可以把抽牙移動(dòng)到遠(yuǎn)離鈑金根部的位置,如改進(jìn)的設(shè)計(jì)中***個(gè)設(shè)計(jì)所示。如果因?yàn)樵O(shè)計(jì)要求,抽牙和折彎的位置都無法移動(dòng),那么可以在抽牙對應(yīng)的折彎根部增加一個(gè)工藝切口,從而保證折彎順利進(jìn)行,如改進(jìn)的設(shè)計(jì)中的第二個(gè)設(shè)計(jì)。

style="text-indent:25px">7、避免折彎干涉由于鈑金折彎公差的存在,在鈑金折彎的運(yùn)動(dòng)方向上,需要保證一定的折彎間隙,以避免折彎時(shí)干涉而造成折彎失敗。圖中所示為一個(gè)具有復(fù)雜折彎鈑金件的簡化圖,折彎順序?yàn)樯蟼?cè)邊先折彎,右側(cè)邊后再折彎。在原始的設(shè)計(jì)中,兩個(gè)折彎邊沒有間隙,當(dāng)上側(cè)邊折彎完成后,再將右側(cè)邊折彎時(shí),因?yàn)殁k金折彎公差的存在,很可能造成右側(cè)邊在折彎過程中與上側(cè)邊干涉;在改進(jìn)的設(shè)計(jì)中,右側(cè)邊與上側(cè)邊保留至少(間隙的大小視折彎公差而變化),可以有效避免折彎干涉。8、保證折彎強(qiáng)度鈑金折彎時(shí)需要保證折彎強(qiáng)度,長而窄的折彎強(qiáng)度低,短而寬的折彎強(qiáng)度高,因此鈑金折彎盡量附著在比較長的邊上。如圖中所示,同樣功能的一個(gè)折彎原始的設(shè)計(jì)中因?yàn)檎蹚澑街诒容^短的邊上而折彎強(qiáng)度低,改進(jìn)的設(shè)計(jì)中折彎附著在比較長的邊而折彎強(qiáng)度高。9、減少折彎工序鈑金折彎工序越多,模具成本就越高,折彎精度就越低,因此鈑金設(shè)計(jì)應(yīng)當(dāng)盡量減少折彎工序。如上圖所示,原始的設(shè)計(jì)中,鈑金需要兩個(gè)折彎工序;在改進(jìn)的設(shè)計(jì)中,鈑金**只需要一個(gè)折彎工序就可以同時(shí)完成兩個(gè)邊的折彎。10、多重折彎上的孔很難對齊很多產(chǎn)品設(shè)計(jì)工程師一定有過這樣的痛苦體會:為什么鈑金件折彎上的螺釘孔或拉釘孔總是對不齊。武漢自動(dòng)鈑金設(shè)計(jì)制造廠</p><p
