無縫方管直角設計法孔型的缺陷

    整個工程項目的無縫方管并不是按照圖紙直接一次性生產完成的而是直接交給施工方。而是一批貨物完成生產后,讓施工工人完成安裝,然后再進行下一批的生產加工。這就要求無縫方管加工廠家的產品誤差不能太大。一開始的小誤差會使無縫方管加工后期的面材出現問題。產品很容易遇到安裝問題,這叫做“一分不誤”這方面,整個無縫方管加工行業其實都是與國家推薦標準相關的這個標準中,相應的參數都是非常仔細和嚴格的通常無縫方管的尺寸和規格由厚度、長度、寬度、下擺高度和對角線差組成。長度和寬度決定了整個無縫方管的基本形狀,而厚度則會影響到整個無縫方管的性能。不論q355b無縫方管類型(xing),厚度(du)誤差(cha)范(fan)(fan)圍(wei)均在+0.1mm以內(nei)。當無(wu)(wu)(wu)縫(feng)方管(guan)長寬(kuan)小于(yu)(yu)(yu)等于(yu)(yu)(yu)2000mm時(shi),長寬(kuan)之間的(de)(de)(de)允(yun)(yun)許(xu)誤差(cha)為(wei)1mm當尺(chi)寸大于(yu)(yu)(yu)2000mm時(shi),長寬(kuan)誤差(cha)不(bu)(bu)(bu)能(neng)超(chao)(chao)(chao)過1.5mm折邊高度(du)的(de)(de)(de)誤差(cha)幅度(du)與無(wu)(wu)(wu)縫(feng)方管(guan)表面尺(chi)寸無(wu)(wu)(wu)關,絕(jue)不(bu)(bu)(bu)能(neng)超(chao)(chao)(chao)過0.5mm對角線差(cha)的(de)(de)(de)允(yun)(yun)許(xu)誤差(cha)范(fan)(fan)圍(wei)是:當無(wu)(wu)(wu)縫(feng)方管(guan)的(de)(de)(de)長度(du)小于(yu)(yu)(yu)等于(yu)(yu)(yu)2000mm時(shi),允(yun)(yun)許(xu)誤差(cha)為(wei)2mm;如果長度(du)大于(yu)(yu)(yu)2000mm誤差(cha)不(bu)(bu)(bu)能(neng)超(chao)(chao)(chao)過3mm無(wu)(wu)(wu)縫(feng)方管(guan)金(jin)屬加工(gong)(gong)是生產線上(shang),由(you)技術工(gong)(gong)人在機器上(shang)進行加工(gong)(gong),由(you)于(yu)(yu)(yu)各(ge)種原因,會使加工(gong)(gong)出來的(de)(de)(de)無(wu)(wu)(wu)縫(feng)方管(guan)單板可能(neng)會有一定的(de)(de)(de)誤差(cha),但是誤差(cha)一定要控制在一定的(de)(de)(de)范(fan)(fan)圍(wei)內(nei),否則就是不(bu)(bu)(bu)合(he)格的(de)(de)(de)產品。這(zhe)些錯誤必須被最(zui)小化,或(huo)者更好的(de)(de)(de)完全避(bi)免(mian)!無(wu)(wu)(wu)論是鈑(ban)金(jin)加工(gong)(gong),還是噴(pen)涂工(gong)(gong)藝,都必須注(zhu)意精度(du)。最(zui)近包括之前(qian)我(wo)都經常能(neng)接到客(ke)戶的(de)(de)(de)電話說要做鋁(lv)合(he)金(jin)門窗(chuang),但是像我(wo)做工(gong)(gong)業鋁(lv)型(xing)材的(de)(de)(de)廠家一樣(yang),一般的(de)(de)(de)鋁(lv)合(he)金(jin)門窗(chuang)我(wo)很少做或(huo)者不(bu)(bu)(bu)做。

       無縫方管有很多相似之處,但又不一樣,原材料都是鋁合金,表面是銀白色陽極化,看起來非常干凈整潔。q355c無縫方管架是(shi)卡(ka)槽(cao),可(ke)(ke)卡(ka)板或玻璃等格(ge)(ge)柵等。兩者有(you)(you)一些(xie)不(bu)(bu)同之(zhi)處:首先看斷面(mian),無(wu)(wu)縫(feng)(feng)方(fang)管(guan)(guan)(guan)(guan)的(de)(de)(de)(de)斷面(mian)復雜性是(shi)不(bu)(bu)同的(de)(de)(de)(de)大(da)多(duo)(duo)(duo)數工(gong)(gong)業(ye)(ye)鋁(lv)(lv)型(xing)(xing)(xing)(xing)(xing)材(cai)(cai)型(xing)(xing)(xing)(xing)(xing)材(cai)(cai)形(xing)狀(zhuang)(zhuang)(zhuang)復雜,周圍有(you)(you)槽(cao)、坑,可(ke)(ke)與多(duo)(duo)(duo)種(zhong)(zhong)尺寸的(de)(de)(de)(de)鋁(lv)(lv)型(xing)(xing)(xing)(xing)(xing)材(cai)(cai)連接(jie)(jie)(jie)。但(dan)(dan)是(shi)門窗鋁(lv)(lv)合(he)(he)金型(xing)(xing)(xing)(xing)(xing)材(cai)(cai)主(zhu)要是(shi)用(yong)來安(an)裝(zhuang)固定(ding)門窗板的(de)(de)(de)(de)斷面(mian)比較簡單。而一般(ban)工(gong)(gong)業(ye)(ye)鋁(lv)(lv)的(de)(de)(de)(de)厚(hou)度(du)(du)大(da)于(yu)等于(yu)1mm被擠壓(ya)功能接(jie)(jie)(jie)受(shou)的(de)(de)(de)(de)厚(hou)度(du)(du)不(bu)(bu)能小(xiao)于(yu)1mm因為要保證鋁(lv)(lv)的(de)(de)(de)(de)承載(zai)能力,厚(hou)度(du)(du)太(tai)薄容易斷裂。其次,無(wu)(wu)縫(feng)(feng)方(fang)管(guan)(guan)(guan)(guan)的(de)(de)(de)(de)門窗價(jia)格(ge)(ge)是(shi)不(bu)(bu)同的(de)(de)(de)(de)這(zhe)是(shi)根本的(de)(de)(de)(de)區別,也(ye)是(shi)所(suo)(suo)關心的(de)(de)(de)(de)一點。因為鋁(lv)(lv)型(xing)(xing)(xing)(xing)(xing)材(cai)(cai)厚(hou)度(du)(du)不(bu)(bu)同所(suo)(suo)以價(jia)格(ge)(ge)也(ye)不(bu)(bu)一樣(yang)。工(gong)(gong)業(ye)(ye)鋁(lv)(lv)型(xing)(xing)(xing)(xing)(xing)材(cai)(cai)也(ye)可(ke)(ke)以做成門窗的(de)(de)(de)(de)框(kuang)架,但(dan)(dan)是(shi)因為它(ta)壁厚(hou)和截(jie)面(mian),所(suo)(suo)以它(ta)價(jia)格(ge)(ge)肯定(ding)是(shi)高(gao)的(de)(de)(de)(de)而門窗鋁(lv)(lv)合(he)(he)金型(xing)(xing)(xing)(xing)(xing)材(cai)(cai)是(shi)很多(duo)(duo)(duo)的(de)(de)(de)(de)不(bu)(bu)利(li)于(yu)客戶節約成本。無(wu)(wu)縫(feng)(feng)方(fang)管(guan)(guan)(guan)(guan)直角(jiao)設計法(fa)孔(kong)(kong)型(xing)(xing)(xing)(xing)(xing)的(de)(de)(de)(de)缺(que)陷針對現有(you)(you)無(wu)(wu)縫(feng)(feng)方(fang)管(guan)(guan)(guan)(guan)直角(jiao)設計法(fa)孔(kong)(kong)型(xing)(xing)(xing)(xing)(xing)的(de)(de)(de)(de)缺(que)陷,提(ti)出(chu)無(wu)(wu)縫(feng)(feng)方(fang)管(guan)(guan)(guan)(guan)孔(kong)(kong)型(xing)(xing)(xing)(xing)(xing)的(de)(de)(de)(de)鈍角(jiao)設計方(fang)法(fa).該(gai)方(fang)法(fa)的(de)(de)(de)(de)基本思路是(shi):不(bu)(bu)影(ying)響無(wu)(wu)縫(feng)(feng)方(fang)管(guan)(guan)(guan)(guan)變(bian)(bian)形(xing)的(de)(de)(de)(de)前提(ti)下,通(tong)過將孔(kong)(kong)型(xing)(xing)(xing)(xing)(xing)頂角(jiao)由直角(jiao)改為按(an)一定(ding)規律變(bian)(bian)化的(de)(de)(de)(de)鈍角(jiao),讓呈臥菱(ling)形(xing)狀(zhuang)(zhuang)(zhuang)的(de)(de)(de)(de)平輥孔(kong)(kong)型(xing)(xing)(xing)(xing)(xing)接(jie)(jie)(jie)納(na)呈立(li)菱(ling)形(xing)狀(zhuang)(zhuang)(zhuang)的(de)(de)(de)(de)管(guan)(guan)(guan)(guan)坯,接(jie)(jie)(jie)著(zhu)讓臥菱(ling)形(xing)狀(zhuang)(zhuang)(zhuang)的(de)(de)(de)(de)管(guan)(guan)(guan)(guan)坯進入立(li)菱(ling)形(xing)狀(zhuang)(zhuang)(zhuang)的(de)(de)(de)(de)立(li)輥孔(kong)(kong)型(xing)(xing)(xing)(xing)(xing),隨(sui)著(zhu)變(bian)(bian)形(xing)的(de)(de)(de)(de)繼續,逐漸(jian)縮小(xiao)菱(ling)形(xing)孔(kong)(kong)型(xing)(xing)(xing)(xing)(xing)對角(jiao)線之(zhi)差直至為零,成為正方(fang)形(xing).這(zhe)樣(yang)設計的(de)(de)(de)(de)無(wu)(wu)縫(feng)(feng)方(fang)管(guan)(guan)(guan)(guan)孔(kong)(kong)型(xing)(xing)(xing)(xing)(xing)優點突出(chu),不(bu)(bu)僅孔(kong)(kong)型(xing)(xing)(xing)(xing)(xing)開(kai)口(kou)大(da)、深度(du)(du)淺、線速度(du)(du)差小(xiao),而且孔(kong)(kong)型(xing)(xing)(xing)(xing)(xing)磨損(sun)小(xiao)、變(bian)(bian)形(xing)阻力小(xiao)、打(da)滑程度(du)(du)輕(qing)、無(wu)(wu)縫(feng)(feng)方(fang)管(guan)(guan)(guan)(guan)表面(mian)質量好.這(zhe)種(zhong)(zhong)避空孔(kong)(kong)型(xing)(xing)(xing)(xing)(xing)邊緣的(de)(de)(de)(de)設計方(fang)法(fa)和設計思想對多(duo)(duo)(duo)種(zhong)(zhong)無(wu)(wu)縫(feng)(feng)方(fang)管(guan)(guan)(guan)(guan)孔(kong)(kong)型(xing)(xing)(xing)(xing)(xing)設計都有(you)(you)借鑒(jian)作用(yong).業(ye)(ye)內人士都知道。
