冷彎、熱彎：一般中小管徑彎頭可以冷彎加工獲得；大管徑的就需要熱彎了。即中頻<a href="http://www.818624.com">彎頭機</a>。煨彎加工一般指現場完成。沖壓彎頭：工程上水系統使用的大多數（尤其大管徑）可以采購成品彎頭，加工方法是沖壓，產品一致性好。中頻<a href="http://www.818624.com">彎頭機</a>推制的彎頭：在80年代末接觸過用機械+模具內胎+中頻加熱方法推制鋼制彎頭的工藝，但后來因為內外側壁厚不易掌控，少見實際應用.</span></p> <p> <span style="font-size:20px;">沖壓彎頭和普通彎頭有什么區別？</span></p> <p> <span style="font-size:20px;">無縫彎頭和沖壓彎頭不是一種，其區別如下：1、熱壓彎頭即沖壓彎頭，它由材料加熱后用特殊模具沖壓而成，直徑較??；焊接彎頭即為“蝦米彎”，它可在管道上或鋼板上切割下料后焊制而成，其規格可為很大。彎的節數與彎曲半徑由制作者自由確定。沖壓彎其光滑度較好，而焊接彎不很圓順，兩者的彎曲半徑均不大，一般為管道直徑的1倍左右，而煨制彎的彎曲半徑為管道直徑的8倍左右，其光滑度也也沖壓彎一樣。2、無縫彎頭是用管彎制而成，可以焊接，所以稱為焊接彎頭，并不是指它自身有焊縫，事實上恰恰相反，焊接彎頭由于是用直管沖壓彎曲而成，考慮到結構受力問題一般使用無縫管。而不是焊接管。，而所謂的無縫彎頭是鑄件，不可焊接。</span></p>
