style="font-size:36px;">冷推彎頭機加工管件的工藝過程</span></p> <p> <span style="font-size:20px;">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，所占比例較大，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?，F(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<a href="http://www.hbjjhltu.cn">冷推彎頭機</a>。</span></p> <p> <span style="font-size:20px;">現(xiàn)在我們重要采用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(yù)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</span><span style="font-size: 20px;">通過彎頭成形機，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(yù)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(guān)鎖去世,然后把管子推下，就加工好一個。校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(dāng)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。制做完成后進行打鋼字、噴涂漆、包裝等工序后，就可以入庫了，然后出廠。
