②吸收振動(dòng)和沖擊能量，如汽車、火車車廂下的緩沖彈片、聯(lián)軸器中的吸振彈片等。 </p> <p> <br /> </p> <p> ③ 貯存及輸出能量作為動(dòng)力，如鐘表彈片、***中的彈片等。 </p> <p> <br /> </p> <p> ④用作測(cè)力元件，如測(cè)力器、彈片秤中的彈片等。彈片的載荷與變形之比稱為彈片剛度，剛度越大，則彈片越硬。按受力性質(zhì)，彈片可分為拉伸彈片、壓縮彈片、扭轉(zhuǎn)彈片和彎曲彈片，按形狀可分為碟形彈片、環(huán)形彈片、板彈片、螺旋彈片、截錐渦卷彈片以及扭桿彈片等。 </p> <p> <br /> </p><p> 拉深件的工序數(shù)量與材料性質(zhì)、拉深高度、拉深階梯數(shù)以及拉深直徑、材料厚度等條件有關(guān)，需經(jīng)拉深工藝計(jì)算才能確定。當(dāng)拉深件圓角半徑較小或尺寸精度要求較高時(shí)，則需在拉深后增加一道整形工序，精密小五金拉伸件工藝大致可分為分離工序和成形工序。 </p> <p> <br /> </p> <p> 分離工序是在沖壓過(guò)程中使其與坯料沿一定的輪廓線相互分離，同時(shí)五金沖壓件分離斷面的質(zhì)量也要滿足一定的要求。 </p> <p> <br /> </p> <p> 成形工序是使沖壓坯料在不破壞的條件下發(fā)生變形，并轉(zhuǎn)化成所要求的五金沖壓件形狀，同時(shí)也應(yīng)滿足尺寸公差等方面的要求。 </p> <p> <br /> </p> <p> <br

=10°～30°的深錐形件，由于深度較大，坯料的變形程度較大，*靠坯料與凸模接觸的局部面積傳遞成形力，極易引起坯料局部過(guò)度變薄乃至破裂，需要經(jīng)過(guò)多次過(guò)渡逐漸成形。階梯拉伸法是首先將坯料拉伸成階梯形過(guò)渡件，其階梯外形與錐形部的內(nèi)形相切，***脹形成錐形。階梯過(guò)渡件的拉伸次數(shù)、工藝等與階梯圓筒件的拉伸相同。矩形再拉伸加工：多次拉伸成形的高矩形件，其變形不*與深圓筒形件的拉伸不同，與低盒形件的變形也有很大差別。圖1-46為多工位自動(dòng)搬送壓力機(jī)進(jìn)行高矩形盒件加工時(shí)，多次拉伸過(guò)程中制件外形、尺寸伴隨拉伸高度的變化。造成表面劃痕的因素有：不銹鋼拉伸件的表面會(huì)出現(xiàn)劃痕是由于工件與模具表面存在相對(duì)的移動(dòng)。深圳本地精密拉伸五金件加工廠</p><p
