1.沖壓拉伸件模具可用于加工尺寸范圍大、形狀復雜的零件，如鐘表等小秒表、汽車縱梁、覆蓋件等。由于沖壓過程中材料的冷變形和硬化效應，沖壓的強度和剛度較高。 </p> <p> <br /> </p> <p> 2.沖壓時，模具保證了沖壓件尺寸和形狀的準確性，一般不會損壞沖壓件的表面質量，模具使用壽命長。因此，沖壓質量穩(wěn)定，互換性好，具有“一模一樣”的特點。 </p> <p> <br /> </p> <p> 3.沖壓一般不產(chǎn)生切屑，材料消耗少，不需要其他加熱設備，是一種節(jié)省材料和能源的加工方法，沖壓件成本較低。 </p> <p> <br /> </p> <p> 4.本發(fā)明生產(chǎn)效率高，操作方便，易于實現(xiàn)機械化和自動化。這是因為沖壓是通過沖壓模具和沖壓設備來完成的。普通壓力機的沖程數(shù)可達到每分鐘幾十次，惠州沖壓精密拉伸五金件廠家，高速壓力可達到每分鐘幾百次甚至幾千次，惠州沖壓精密拉伸五金件廠家，惠州沖壓精密拉伸五金件廠家，每個沖壓沖程可獲得一個沖頭。 </p> <p> <br />

拉伸系數(shù)非常重要，一個拉伸件需要分幾步拉伸才能保證不出現(xiàn)開裂、起皺等問題都需要用拉伸系數(shù)公式進行計算。是拉伸工藝核算中的首要工藝參數(shù)之一，一般用它來決議拉伸的次序和次數(shù)。 </p> <p> <br /> </p> <p> 但是，拉伸系數(shù)也不是固定不變的。影響拉伸系數(shù)m的因素比較多，其中包括：材料型號、厚度、拉伸結構類型、拉伸次數(shù)、拉伸速度、拉伸鑲件圓弧過度大小等等。不過，一般都可以查表進行大概計算。 </p> <p> <br /> </p><p style="text-indent:25px">金屬拉伸工藝應結合工廠的設備、人員等實際情況，從零件的質量、生產(chǎn)效率、生產(chǎn)成本、勞動強度、環(huán)境的保護以及生產(chǎn)的安全性各個方面綜合考慮，選擇和設計出技術先進、經(jīng)濟上合理、使用安全可靠的工藝方案，使生產(chǎn)在保證達到設計圖樣上所提出的各項技術要求的基礎上，盡可能降低工藝成本和保證安全生產(chǎn)圓筒拉伸：法蘭與底部均為直面，圓筒為軸對稱，在同一圓周上變形均勻，法蘭上毛坯產(chǎn)生拉深變形,法蘭上毛坯拉伸變形，但變形量與變形比沿輪廓形狀相應變化。曲率越大的部分毛坯的變形量就越大;曲率越小的部分毛坯的變形越小。多次拉伸可以提高產(chǎn)品的合格率，不容易產(chǎn)生廢品，多次拉伸的中間去應力，退火軟化。</p><div

=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度變薄乃至破裂，需要經(jīng)過多次過渡逐漸成形。階梯拉伸法是首先將坯料拉伸成階梯形過渡件，其階梯外形與錐形部的內形相切，***脹形成錐形。階梯過渡件的拉伸次數(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為多工位自動搬送壓力機進行高矩形盒件加工時，多次拉伸過程中制件外形、尺寸伴隨拉伸高度的變化。這兩種特殊水泥涂層均適用于沖壓拉伸件的內防腐，提高抵抗侵蝕的能力。廣州耐磨精密拉伸五金件工廠</p><p

選擇拉伸材料中，要注意屈服點、抗拉強度的比值越小，拉深性能越好，一次變形的極限程度越大越有利于降低成本以及保證拉伸的質量。不銹鋼拉伸是拉伸工藝中經(jīng)常見到的，很多拉伸件經(jīng)常用到不銹鋼。但由于不銹鋼的延展率比較小，彈性模量也比較大，硬化**比較高。拉伸時會出現(xiàn)開裂有時會出現(xiàn)拉伸變形后；有時會在拉伸件由凹模內退出的時候發(fā)生；有時在拉伸變形后受到撞擊或者振動時才出現(xiàn)；有時在拉伸變形后經(jīng)過一段時間的存放或者使用中出現(xiàn)開裂。
