style="font-size:22px;">因無(wú)縫管直徑規(guī)格較多，彎管R尺寸較多，故每次直徑有變化，R尺寸就有變化，必須更換彎管模具，每次更換都很麻煩，要制造許多模具，還要每次調(diào)整。我們都知道<a href="http://m.chikumakai.com">彎管機(jī)</a>是要求壓出不同形態(tài)的管材，而管材對(duì)于不同形狀的要求就需要彎管機(jī)具有匹配各種管材的模具。</span></div> <div> <span style="font-size:22px;"> 形夾模使用方法與R形夾?；鞠嗤蚱浣Y(jié)構(gòu)有變化，應(yīng)用時(shí)與R形夾模有區(qū)別，需要注意的工藝方法如下：</span></div> <div> <span style="font-size:22px;">1、導(dǎo)模與夾模的v形尺寸應(yīng)統(tǒng)一，便于觀察與調(diào)整模具。經(jīng)過(guò)改進(jìn)一年可節(jié)約了近20種模具，減少了調(diào)整時(shí)間，取得了明顯的經(jīng)濟(jì)效益。下圖為夾模簡(jiǎn)圖，導(dǎo)模形狀與夾模差不多，長(zhǎng)度長(zhǎng)一些，故省略。</span></div> <div> <span style="font-size:22px;">2、用v形夾模夾緊時(shí)，夾模與輪模有時(shí)有間隙，間隙的大小與管子直徑大小有關(guān)，當(dāng)管子直徑為φ10mm時(shí)，間隙減小。隨著管子直徑的增加間隙逐漸加大，但不影響裝夾與加工。如遇到大于φ18mm管子時(shí)，要更換v形夾模、輪模與導(dǎo)模。與v形夾模不同，如用R形夾模裝夾，夾模與輪模之間的間隙是沒(méi)有變化的。</span></div> <div> <span style="font-size:22px;">3、在彎材料較軟較薄的管子時(shí)，在夾緊部分應(yīng)穿心軸，阻止變形。</span></div> <div> <span style="font-size:22px;">4、夾模與輪模是同時(shí)旋轉(zhuǎn)彎管的，夾緊力不需太大，故夾模的夾緊力根據(jù)管子直徑、管壁厚度適當(dāng)夾緊，觀看管子沒(méi)有變形即可。否則用力過(guò)大，管子會(huì)產(chǎn)生變形(因輪模是 面受力，夾模是兩條線夾緊)。</span></div> <div> <span style="font-size:22px;">5、彎管時(shí)夾緊部分不能過(guò)短，否則容易造成管子變形，保證20mm即可。</span></div> <div> <span style="font-size:22px;"> 為了提高生產(chǎn)率，節(jié)約產(chǎn)品成本，我們?cè)O(shè)計(jì)改造了模具結(jié)構(gòu)。原來(lái)每套模具需要三種零件，現(xiàn)在經(jīng)改進(jìn)把原R形夾模、導(dǎo)模改為v形夾模、導(dǎo)模。這樣，一般φ10～φ18mm無(wú)縫管的彎管，夾模與導(dǎo)模就不用更換了。如果彎管R變化也無(wú)妨，只需要將輪模配換就可以了。</span></div>
