33、和非磁性堆垛機。一類是磁性堆垛機。軋件由裝有可調(diào)磁性的翻轉(zhuǎn)臂和輸送小車進行一車堆垛，并且層與層之間是面對面或背對背交替放鋼材堆垛后，由平立輥道輸送到打捆區(qū)，平立輥道的寬度是可調(diào)的，以避免料垛散落。另一類是非磁性堆垛機。軋制由兩套液壓一機械機構(gòu)控制的機械手進層層堆垛其動作類似于人手。可夾持并移送鋼材，將鋼材層面對面或背對背的進行堆放，主要適用于中小斷面型鋼，可避免料層中鋼材在堆垛臂失磁時散落。形成不正確的料捆成形狀非磁性堆垛機即純機械堆垛機的顯著特點就是無故障的處理雙層型鋼的能力，故其機械效率可提高一倍。傳動機構(gòu)通常分為機械傳動、電器傳動和流體傳動。機械傳動是最初的傳動方式也是最重要的傳動方式之一，它是在電動機等動力源的驅(qū)動下通過一定的機械式傳動機構(gòu)（齒輪機構(gòu)、帶傳動和鏈傳動等）得到期望的運動參數(shù)。流體傳動是以流體為工作介質(zhì)進行能量替換、傳遞和控制的傳動。它包括液體傳動和氣體傳動，液體傳動是以液體為工作介質(zhì)的流體傳動，它包括液力傳動和液壓傳動。 其中機電傳動和液壓傳動是最常用的兩類傳動。電動機分為交流電動機和直流電動機兩大類，交流電動機又分為交流電動機和直流電動機兩類。在強電系統(tǒng)中三相交流異步電動機結(jié)構(gòu)簡單，運行可靠，成本低廉等優(yōu)點，廣泛應(yīng)用于工農(nóng)業(yè)生
