style="text-indent:25px">鉗工：沉孔、攻絲、擴(kuò)孔、鉆孔。沉孔角度一般120℃，用于拉鉚釘，90℃用于沉頭螺釘，攻絲英制底孔。翻邊：又叫抽孔、翻孔，就是在一個較小的基孔上抽成一個稍大的孔，再攻絲，主要用板厚比較薄的鈑金加工，增加其強(qiáng)度和螺紋圈數(shù)，避免滑牙，一般用于板厚比較薄，其孔周正常的淺翻邊，厚度基本沒有變化，允許有厚度的變薄30-40%時，可得到比正常翻邊高度大高40-60%的高度，用擠薄50%時，可得大的翻邊高度，當(dāng)板厚較大時，如2.0、2.5等以上的板厚，便可直接攻絲。沖床：是利用模具成形的加工工序，一般沖床加工的有沖孔、切角、落料、沖凸包（凸點(diǎn)），沖撕裂、抽孔、成形等加工方式，其加工需要有相應(yīng)的模具來完成操作，如沖孔落料模、凸包模、撕裂模、抽孔模、成型模等，操作主要注意位置，方向性。鈑金注重的是剛度不是強(qiáng)度，折彎件的截面設(shè)計要合理。</p><div

style="text-indent:25px">預(yù)先加工好孔的毛坯料，在彎曲時如果孔位于彎曲變形區(qū)內(nèi)，那么孔的形狀在折彎后會拉伸變形，同時也會影響折彎后配件尺寸。為了避免孔位分布在折彎變形區(qū)內(nèi)，一般應(yīng)保證孔邊距離b（折彎后外邊至孔邊的近距離）≥3倍板厚。對于平行于彎曲線的橢圓形孔，為保證折彎精度和防止孔位變形，孔邊距離一般應(yīng)≥4倍板厚。如果孔位必須分布在變形區(qū)內(nèi)，則為了保證精度，一般采用先加工小孔，待折彎后再擴(kuò)孔的方法達(dá)到要求，也可在折彎位置沖工藝孔或缺口來轉(zhuǎn)移變形區(qū)。常用的鈑金材料有不銹鋼、鍍鋅鋼板、馬口鐵、銅、鋁、鐵等。普陀區(qū)鈑金加工一般多少錢</p><p

style="text-indent:25px">鈑金折彎過程可分為三類：局部彎曲、閉合彎曲和壓花彎曲局部彎曲：右彎曲和鈍角彎曲的方法是選擇88度以下的上模和V=12t（槽寬V，材料厚度T）的下模。閉合彎曲：選用直角和鈍角90度彎曲的方法。近彎下模選用V=6~12t。壓花彎曲：直角彎曲選用90度上模（標(biāo)準(zhǔn)直角彎曲），壓彎下模選用V=5~6t。鈑金加工在折彎過程中如要提高折彎速度，齒輪開關(guān)可以在單一或連續(xù)狀態(tài)下操作，但為了安全起見，通常只在單一動作中使用。彎曲長零件時，中間的角度通常很大。我們可以調(diào)整CC軸來改變中間的角度以達(dá)到與左右兩側(cè)相同的角度。在彎曲過程中，還應(yīng)注意中心彎曲的原理，這是保證彎曲精度的重要前提。普陀區(qū)鈑金加工一般多少錢</p></p><br
