六角頭螺栓分外六角螺栓和內(nèi)六角螺栓，是常用的緊固件，主要用作機械設(shè)備的緊固。無論是外六角還是內(nèi)六角，它們的規(guī)格尺寸表示方法都是類似的。外六角螺栓國家標(biāo)準(zhǔn)GB/T5782-86，這個標(biāo)準(zhǔn)規(guī)定了螺紋規(guī)格為M3~M64，A和B級的六角頭螺栓，A級用于D<=24和L<=10D或L。 </p> <p> <br /> </p> <p> 六角頭螺栓產(chǎn)品等級分為A、B、C三級，表示精度，其中A級精確，C級精度差。精度不同，作用的地方也不同，A級比B級高，要求高的地方用A級，大多數(shù)都選用B級。A級用于承載較大，要求精度高或受沖擊、振動載荷的場合。 </p> <p> <br /> 固原螺栓推薦螺栓的類型分為哪些？</p><div

高強度螺栓摩擦型和承壓型連接的區(qū)別： </p> <p> 高強螺栓連接是通過螺栓桿內(nèi)很大的擰緊預(yù)拉力把連接板的板件夾緊，足以產(chǎn)生很大的摩擦力，從而提高連接的整體性和剛度，當(dāng)受剪力時，按照設(shè)計和受力要求的不同，可分為高強螺栓摩擦型連接和高強螺栓承壓型連接兩種，兩者的本質(zhì)區(qū)別是極限狀態(tài)不同，雖然是同一種螺栓，但是在計算方法、要求、適用范圍等方面都有很大的不同。在抗剪設(shè)計時，高強螺栓摩擦型連接是以外剪力達(dá)到板件接觸面間由螺栓擰緊力所提供的可能大摩擦力作為極限狀態(tài)，也即是保證連接在整個使用期間內(nèi)外剪力不超過大摩擦力。板件不會發(fā)生相對滑移變形（螺桿和孔壁之間始終保持原有的空隙量），被連接板件按彈性整體受力。在抗剪設(shè)計時，高強螺栓承壓型連接中允許外剪力超過大摩擦力，這時被連接板件之間發(fā)生相對滑移變形，直到螺栓桿與孔壁接觸，此后連接就靠螺栓桿身剪切和孔壁承壓以及板件接觸面間的摩擦力共同傳力，以桿身剪切或孔壁承壓破壞作為連接受剪的極限狀態(tài)。 </p><p> 高強度螺栓的連接方式有摩擦連接、承壓連接、混合連接和并用連接和張拉回連接四種 </p> <p> （ 1 ）摩擦型連接：摩擦型高強螺栓是一般常說的高強螺栓，基于高強螺栓緊固時產(chǎn)生的強大夾緊力來壓緊鋼板束，依靠接觸面間產(chǎn)生的抗剪摩擦力傳遞與螺栓垂直方向應(yīng)力的連接方法。 </p> <p> ( 2 ）承壓型連接：是在螺栓擰緊后所產(chǎn)生的抗滑移力及螺栓桿在螺孔內(nèi)和連接鋼板間產(chǎn)生的承壓力來傳遞應(yīng)力的一種連接方法。 </p> <p> ( 3 ）張拉型連接：接頭在螺栓擰緊后，鋼板間產(chǎn)生的壓力使靂板層處于密貼狀態(tài)，螺栓在軸向拉力作用下，板層間的壓力減少，外力完成由螺栓承擔(dān)。當(dāng)外力作用超過螺拴的預(yù)拉力時，板層間就互相離開，發(fā)生離間時的荷載叫做離間荷載，張拉連接其外力應(yīng)小于離間荷載。 </p> <p> ( 4 ）混合連接和并用連接：在高強螺栓的接頭中，同時有幾種方法承受外力，這些連接中有高強螺栓的摩擦型連接和承壓型連接并用；有高強螺栓連接和焊接混用；有高強螺栓和鉚釘并用等，混合連接時，一個接頭中兒種外力由各自的連接分別承受；并用連接時，一個接頭中幾種連接承受一種外力。 </p> <p> <br /> 高強度螺栓有哪些分類？</p><div style="width:100%;text-align:

高強螺栓所用材料的比較大抗拉強度與淬火處理有很大關(guān)系，40Cr淬火處理后一般較難達(dá)到10.9S級高強螺栓的材質(zhì)要求，在不是很嚴(yán)格的檢驗中，可以根據(jù)淬火處理后的表面硬度來判斷材料的比較大抗拉強度。除了處理工藝中的性能不同外，材質(zhì)不同的高強螺栓，其在高應(yīng)力狀態(tài)下的延遲性斷裂性能也是有所不同的。 </p> <p> 40Cr高強螺栓主要用于螺栓球節(jié)點網(wǎng)架中，其設(shè)計強度一般為390MPa(d>=30mm)或者430MPa（d<30mm)，使用中不存在很高的預(yù)拉應(yīng)力。當(dāng)用于要施加很高預(yù)拉力的情況時，要注意了解和保證其延遲性斷裂性能。20MnTiB高強螺栓的延遲性斷裂性能好于40B的。標(biāo)準(zhǔn)螺栓的長度有哪些？固原螺栓推薦</p><p style="text-indent:25px">螺栓怎么處理表面污漬？固原螺栓推薦</p><p> 高強度螺栓連接是靠連接件接觸面間的摩擦力來阻止其相互滑移的，為使接觸面有足夠的摩擦力，就必須提高構(gòu)件的夾緊力和增大構(gòu)件接觸面的摩擦系數(shù)。構(gòu)件間的夾緊力是靠對螺栓施加預(yù)拉力來實現(xiàn)的，所以螺栓必須采用高強度鋼制造，這也就是稱為高強度螺栓連接的原因。 </p> <p> 高強度螺栓連接中，摩擦系數(shù)的大小對承載力的影響很大。試驗表明，摩擦系數(shù)主要受接觸面的形式和構(gòu)件的材質(zhì)影響。為了增大接觸面的摩擦系數(shù)，施工時常采用應(yīng)噴砂、用鋼絲刷清理等方法對連接范圍內(nèi)構(gòu)件接觸面進行處理。 </p> <p> <br /> 固原螺栓推薦</p><p
