36px;">彎頭冷推成型機的主要結構</span></h3> <h3> </h3> <div> </div> <div> <h3> <span style="font-size: 22px;">彎頭冷推成型機主要用于碳鋼、不銹鋼1D、1.5D彎頭冷推成型，推制方法有鋼球過球推制和芯棒成型推制兩種，芯棒成型推制配有半主動機器脫模裝置。主機包括機身（框架）、合模缸、側推缸、脫模結構構成，控制結構由動力站，限位裝置，管路及電氣控制箱，操縱箱構成。成形原理：管坯在由外力鎖緊的隧道模腔中，被液壓頂桿從導向段推入設置了內(nèi)芯的成形腔彎曲成形，并由脫料裝置脫模，全程可接納PLC控制系統(tǒng)操縱。180度翻芯脫模。</span></h3> </div> <div> <span style="font-size: 22px;">彎頭是用于管道轉(zhuǎn)彎處的一種管件。在管道體系所利用的全部管件中，所占比例大，約為80%左右。通常，對差別質(zhì)料或壁厚的彎頭選擇差另外成形工藝。現(xiàn)在制造廠常用的無縫彎頭成形工藝有熱推、沖壓、擠壓等。分為熱推彎頭機和冷推彎頭機。</span></div> <div> <span style="font-size: 22px;">現(xiàn)在我們重要接納冷擠壓彎頭成型方法。冷擠壓彎頭的成形歷程是利用常用的彎頭成形機，將管坯放入外模中，上下模合模后，在推桿的推動下，管坯沿內(nèi)模和外模預留的間隙活動而完成成形歷程。通過冷擠壓推制彎頭原理很簡樸，冷擠壓彎頭的成形歷程是利用常用的彎頭成形機，將管坯放入外模中，上下模合模后，在推桿的推動下，管坯沿內(nèi)模和外模預留的間隙活動而完成成形歷程。它是由一個牛角狀芯頭或芯棒放入模具中，將管件放入模具，模具要有兩 個半圓弧，上下各一個，在推制歷程是一個沿著芯棒彎曲的歷程。后邊有支持，把下料管段穿入芯棒，后邊有一牌樓架將芯棒牢固。中心有液壓頂桿裝置,通過液壓傳動頂柱往前推動。推著管子沿著模具半圓槽順著芯棒往前走，直至頂柱到達盡頭位置,限位開關鎖去世,然后把管子推下，就加工好一個。矯正后的外徑就到達了制品的尺寸要求了。壁厚就以來料的壁厚舉行控制。在推制歷程中，正常環(huán)境下壁厚不該當產(chǎn)生變革，但要是由于東西緣故原由，有的地方會產(chǎn)生減壁征象，以是一樣通常提料時，壁厚要加一些余量，防備在推制時由于局部減厚而超差。彎頭的外徑、壁厚尺寸都到達了要求。下面就舉行精整工序，顛末噴丸處置處罰，把彎頭內(nèi)外表面的氧化鐵皮去掉，把兩頭舉行坡口處理以便于焊接。再顛末查抄、打鋼字、噴涂漆、包裝等工序后，就可以入庫了，然后出廠。</span></div>
