href="http://">液壓彎管機</a>一種新型的具有彎管功能及起頂功能的彎管工具。具有結(jié)構(gòu)合理、使用安全、操作方便、價格合理、裝卸快速、便于攜帶、一機多用等眾多優(yōu)點。</span></div> <div> <span style="font-size:22px;">應(yīng)用領(lǐng)域：液壓彎管機主要用于工廠、倉庫、碼頭、建筑、鐵路、汽車等安裝管道和修理。它除了具有彎管功能外，還能卸下彎管部件（油缸）作為分離式<a href="http://">液壓彎管機</a>的基本工作原理是,通過確定合理的支點和受力點并施加彎曲力矩,使鋼管發(fā)生塑性變形,從而實現(xiàn)鋼管的冷彎曲。下模位于<a href="http://">彎管機</a>的前部,由液壓缸將其懸掛在機架上呈浮動狀態(tài)。彎管時,下模上升使鋼管受彎,因下模上升而產(chǎn)生的作用力是彎管時的主動力。上模吊掛在機架中部,彎管時上模和機架貼緊,起支點作用。夾具位于彎管機的尾部,彎管時能將鋼管一端卡緊,同時又能適應(yīng)鋼管因軸線撓曲而發(fā)生的角度變化。當(dāng)下模上升時,鋼管橫向受力和梁受彎狀態(tài)相同。上模中心和夾具均受支座反力,下模上升給鋼管施加的力逐漸增大到某一值時,下部管壁上的拉伸應(yīng)力達到鋼材的屈服極限,于是鋼管產(chǎn)生塑性變形而彎曲。</span></div>
