不(bu)銹(xiu)鋼(gang)瓦楞(leng)形板是不(bu)銹(xiu)鋼(gang)寬(kuan)幅型鋼(gang)的一種(zhong)，由于其形狀如同(tong)頂(ding)上用瓦片鋪成的行列隆起部分，故(gu)稱為香蕉視頻app連接:不銹鋼瓦楞形板(ban)，如圖5-37所示。

 人們(men)過去常見的“瓦楞(leng)（形）板”大都是(shi)用普(pu)通低碳(tan)鋼，也(ye)就(jiu)是(shi)非合(he)金(jin)鋼材(cai)(cai)料(liao)(liao)制(zhi)成(cheng)的（見圖5-38),還有用非金(jin)屬(shu)材(cai)(cai)料(liao)(liao)如石棉、塑料(liao)(liao)、紙板等制(zhi)成(cheng)的瓦楞(leng)形板。這(zhe)些瓦楞(leng)形板主(zhu)要(yao)用于(yu)建筑領域的屋頂材(cai)(cai)料(liao)(liao)、外墻材(cai)(cai)料(liao)(liao)和(he)(he)各(ge)種(zhong)包裝(zhuang)箱(xiang)體的外形材(cai)(cai)料(liao)(liao)和(he)(he)產品包裝(zhuang)箱(xiang)、盒等，之所(suo)以做成(cheng)瓦楞(leng)形狀，主(zhu)要(yao)目(mu)的是(shi)增加結構剛度(du)和(he)(he)穩定性(xing)。因此，其尺寸精度(du)和(he)(he)表(biao)面質量要(yao)求及(ji)材(cai)(cai)質要(yao)求都不是(shi)很高。

 此(ci)處介紹的(de)(de)(de)(de)不(bu)(bu)銹(xiu)鋼(gang)瓦(wa)(wa)楞形(xing)(xing)(xing)板與普(pu)通(tong)(tong)(tong)的(de)(de)(de)(de)“瓦(wa)(wa)楞（形(xing)(xing)(xing)）板”有著本質(zhi)的(de)(de)(de)(de)不(bu)(bu)同，首先材料是(shi)(shi)不(bu)(bu)銹(xiu)鋼(gang)，無(wu)疑要(yao)(yao)比普(pu)通(tong)(tong)(tong)的(de)(de)(de)(de)“瓦(wa)(wa)楞（形(xing)(xing)(xing)）板”具(ju)有更高的(de)(de)(de)(de)強度、良好的(de)(de)(de)(de)耐(nai)腐(fu)蝕(shi)性能(neng)(neng)和(he)(he)極好的(de)(de)(de)(de)裝飾(shi)效果(guo)，另外在(zai)結構(gou)上(shang)也大不(bu)(bu)相同。這(zhe)些都(dou)賦予(yu)了(le)不(bu)(bu)銹(xiu)鋼(gang)瓦(wa)(wa)楞形(xing)(xing)(xing)板不(bu)(bu)僅具(ju)有普(pu)通(tong)(tong)(tong)“瓦(wa)(wa)楞形(xing)(xing)(xing)板”的(de)(de)(de)(de)各(ge)種(zhong)功(gong)能(neng)(neng)與作(zuo)(zuo)用(yong)，而且具(ju)有普(pu)通(tong)(tong)(tong)“瓦(wa)(wa)楞（形(xing)(xing)(xing)）板”沒有的(de)(de)(de)(de)功(gong)能(neng)(neng)，即不(bu)(bu)銹(xiu)鋼(gang)瓦(wa)(wa)楞形(xing)(xing)(xing)板可以作(zuo)(zuo)為(wei)傳(chuan)熱元(yuan)件(jian)使用(yong)。作(zuo)(zuo)為(wei)傳(chuan)熱元(yuan)件(jian)，對其各(ge)方面的(de)(de)(de)(de)要(yao)(yao)求(qiu)(qiu)就比普(pu)通(tong)(tong)(tong)“瓦(wa)(wa)楞（形(xing)(xing)(xing)）板”高得多，特(te)別(bie)是(shi)(shi)對瓦(wa)(wa)楞形(xing)(xing)(xing)板表(biao)觀(guan)的(de)(de)(de)(de)要(yao)(yao)求(qiu)(qiu)。對瓦(wa)(wa)楞形(xing)(xing)(xing)板表(biao)觀(guan)的(de)(de)(de)(de)要(yao)(yao)求(qiu)(qiu)主(zhu)(zhu)要(yao)(yao)體現在(zai)對外形(xing)(xing)(xing)尺寸和(he)(he)表(biao)面質(zhi)量的(de)(de)(de)(de)要(yao)(yao)求(qiu)(qiu)上(shang)。因此(ci)，采用(yong)何種(zhong)方式、何種(zhong)工藝加工生產不(bu)(bu)銹(xiu)鋼(gang)瓦(wa)(wa)楞形(xing)(xing)(xing)板就成為(wei)保證其外形(xing)(xing)(xing)尺寸和(he)(he)質(zhi)量的(de)(de)(de)(de)關(guan)鍵。其他性能(neng)(neng)（機(ji)械性能(neng)(neng)、耐(nai)腐(fu)蝕(shi)性能(neng)(neng)和(he)(he)焊接性能(neng)(neng)）主(zhu)(zhu)要(yao)(yao)取決于(yu)所選用(yong)的(de)(de)(de)(de)材料。

1. 不銹鋼瓦楞形板外(wai)形尺寸

 從圖(tu)5-37和(he)圖(tu)5-39可以(yi)看出不(bu)(bu)銹(xiu)鋼瓦楞形(xing)板的(de)(de)(de)外表(biao)形(xing)狀(zhuang)是有(you)(you)規律(lv)(lv)、周期性變(bian)化的(de)(de)(de)，而且(qie)彎曲深度(du)較小、形(xing)狀(zhuang)單(dan)一(yi)，不(bu)(bu)僅有(you)(you)橫向(xiang)波紋，而且(qie)還(huan)有(you)(you)縱(zong)向(xiang)波紋。所以(yi)說，其形(xing)狀(zhuang)既簡單(dan)又(you)復雜(za)，簡單(dan)是指形(xing)狀(zhuang)單(dan)一(yi)，有(you)(you)規律(lv)(lv)；復雜(za)是指不(bu)(bu)僅有(you)(you)橫向(xiang)波紋，而且(qie)還(huan)有(you)(you)縱(zong)向(xiang)波紋。這就給不(bu)(bu)銹(xiu)鋼瓦楞形(xing)板的(de)(de)(de)成型帶來不(bu)(bu)小的(de)(de)(de)難度(du)，在成型工(gong)藝(yi)(yi)上必須采取相應的(de)(de)(de)工(gong)藝(yi)(yi)措施和(he)手段，方能保證獲得要求的(de)(de)(de)外形(xing)尺(chi)寸和(he)成型質(zhi)量。

 圖5-39是(shi)不(bu)銹鋼瓦楞(leng)形板的實物照片，從(cong)圖片可以看出，不(bu)銹鋼瓦楞(leng)形板的外表和形狀是(shi)非常(chang)美觀、漂亮的，具有較高(gao)的觀賞性(xing)，如同(tong)工藝品、裝飾品。

 圖(tu)5-39不(bu)銹鋼瓦楞形板(ban)A-A截(jie)面尺(chi)寸，見圖(tu)5-40,B-B截(jie)面尺(chi)寸，見圖(tu)5-41。

 不銹鋼瓦(wa)楞形板成品實物斷面(mian)圖(tu)片，見圖(tu)5-40(b)和圖(tu)5-41(b)。

 從圖5-40和圖5-41可以看(kan)出，不銹鋼瓦(wa)楞形(xing)板的(de)斷面變化的(de)規律是周期性的(de)，斷面形(xing)狀是關于(yu)縱向(xiang)中心線為(wei)對稱的(de)型(xing)鋼，彎(wan)曲(qu)深(shen)(shen)度(du)較淺(qian)，深(shen)(shen)度(du)僅有7mm。

 不(bu)銹(xiu)鋼瓦楞形(xing)板外形(xing)尺寸精度(du)：截(jie)面最大邊長誤差≤0.3mm;圓角最大直徑：≤2.0mm;縱(zong)向、橫向彎曲度(du)：每米(mi)≤1mm; 扭轉(zhuan)：每米(mi)≤1°。

 圖(tu)5-42是各(ge)架次成型輥輥形尺寸圖(tu)。

 第(di)(di)三架成型輥(gun)(gun)(gun)輥(gun)(gun)(gun)形圖(tu)(tu)和孔形圖(tu)(tu)，見圖(tu)(tu)5-43.第(di)(di)三架成型輥(gun)(gun)(gun)應是由多(duo)片(pian)輥(gun)(gun)(gun)片(pian)疊加(jia)組(zu)合而(er)成的(de)(de)(de)組(zu)合輥(gun)(gun)(gun)，輥(gun)(gun)(gun)片(pian)的(de)(de)(de)水平段(duan)和圓(yuan)弧段(duan)采(cai)取(qu)與板材接觸(chu)(chu)的(de)(de)(de)方(fang)式(shi)，而(er)傾(qing)斜段(duan)則采(cai)取(qu)與板材不接觸(chu)(chu)的(de)(de)(de)方(fang)式(shi)，為的(de)(de)(de)是減少成型表(biao)面的(de)(de)(de)擦劃傷，此(ci)外，如(ru)此(ci)結構(gou)也將便于成型輥(gun)(gun)(gun)的(de)(de)(de)加(jia)工和隨后的(de)(de)(de)使用與維護等。上(shang)、下輥(gun)(gun)(gun)斜角采(cai)取(qu)圓(yuan)弧過渡，一般情況下，圓(yuan)弧的(de)(de)(de)直徑應大(da)于板厚，所以圖(tu)(tu)5-43所示的(de)(de)(de)第(di)(di)三架上(shang)、下輥(gun)(gun)(gun)斜角的(de)(de)(de)圓(yuan)弧過渡直徑為2.0mm,見圖(tu)(tu)5-43局部(bu)放(fang)大(da)圖(tu)(tu)。

3. 縱(zong)向波紋(wen)的成型

 縱(zong)向(xiang)(xiang)(xiang)波(bo)(bo)紋的(de)(de)成(cheng)(cheng)型(xing)(xing)是在橫(heng)向(xiang)(xiang)(xiang)波(bo)(bo)紋成(cheng)(cheng)型(xing)(xing)之后的(de)(de)橫(heng)向(xiang)(xiang)(xiang)波(bo)(bo)紋上(shang)成(cheng)(cheng)型(xing)(xing)的(de)(de)。所以在已成(cheng)(cheng)型(xing)(xing)的(de)(de)波(bo)(bo)紋上(shang)再成(cheng)(cheng)型(xing)(xing)縱(zong)向(xiang)(xiang)(xiang)波(bo)(bo)紋是有(you)難度的(de)(de)。其難度主要表現為，可(ke)能(neng)破壞已成(cheng)(cheng)型(xing)(xing)的(de)(de)橫(heng)向(xiang)(xiang)(xiang)波(bo)(bo)紋，而且(qie)縱(zong)向(xiang)(xiang)(xiang)波(bo)(bo)紋也成(cheng)(cheng)型(xing)(xing)不好。選用何種方(fang)式成(cheng)(cheng)型(xing)(xing)就成(cheng)(cheng)為縱(zong)向(xiang)(xiang)(xiang)波(bo)(bo)紋成(cheng)(cheng)型(xing)(xing)的(de)(de)關鍵。

 沖(chong)壓成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)輥(gun)(gun)就是在一對(dui)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)輥(gun)(gun)上，按工藝和產(chan)品的(de)(de)(de)(de)(de)要求，在要面(mian)上間(jian)隙分布著凸(tu)起(qi)(qi)(qi)和凹陷(xian)的(de)(de)(de)(de)(de)部(bu)(bu)(bu)分，用于(yu)(yu)壓制成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)瓦楞(leng)(leng)形(xing)(xing)(xing)板(ban)(ban)的(de)(de)(de)(de)(de)縱向(xiang)波(bo)(bo)紋(wen)，同時(shi)(shi)又不能損壞已(yi)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)的(de)(de)(de)(de)(de)橫向(xiang)梯形(xing)(xing)(xing)波(bo)(bo)紋(wen)，縱向(xiang)波(bo)(bo)紋(wen)尺(chi)寸圖(tu)及實物圖(tu)片，見(jian)圖(tu)5-40和圖(tu)5-41。之(zhi)所以(yi)(yi)(yi)將沖(chong)壓成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)輥(gun)(gun)置于(yu)(yu)橫向(xiang)波(bo)(bo)紋(wen)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)輥(gun)(gun)后(hou)、平(ping)整輥(gun)(gun)前(qian)，是為了保證瓦楞(leng)(leng)形(xing)(xing)(xing)板(ban)(ban)的(de)(de)(de)(de)(de)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)過程的(de)(de)(de)(de)(de)穩定(ding)和成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)質(zhi)(zhi)量。可以(yi)(yi)(yi)想象，在沒(mei)有橫向(xiang)波(bo)(bo)紋(wen)的(de)(de)(de)(de)(de)平(ping)板(ban)(ban)帶材上沖(chong)壓成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)凸(tu)起(qi)(qi)(qi)和凹陷(xian)型(xing)(xing)材，由于(yu)(yu)自(zi)由度大沒(mei)有約束力，沖(chong)壓成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)會(hui)(hui)造(zao)成(cheng)(cheng)(cheng)(cheng)(cheng)坯料局部(bu)(bu)(bu)收縮，產(chan)生皺(zhou)折及其他缺陷(xian)，影響(xiang)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)質(zhi)(zhi)量和成(cheng)(cheng)(cheng)(cheng)(cheng)品的(de)(de)(de)(de)(de)尺(chi)寸。另外，瓦楞(leng)(leng)形(xing)(xing)(xing)板(ban)(ban)型(xing)(xing)鋼(gang)截面(mian)受材料內部(bu)(bu)(bu)殘余(yu)應(ying)力作用，很容(rong)易(yi)產(chan)生扭轉(zhuan)，這(zhe)也會(hui)(hui)影響(xiang)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)過程的(de)(de)(de)(de)(de)穩定(ding)性。但在瓦楞(leng)(leng)形(xing)(xing)(xing)板(ban)(ban)橫向(xiang)波(bo)(bo)紋(wen)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)輥(gun)(gun)后(hou)、平(ping)整輥(gun)(gun)前(qian)，再用沖(chong)壓輥(gun)(gun)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)其縱向(xiang)波(bo)(bo)紋(wen)，此時(shi)(shi)，已(yi)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)的(de)(de)(de)(de)(de)橫向(xiang)波(bo)(bo)紋(wen)使瓦楞(leng)(leng)形(xing)(xing)(xing)板(ban)(ban)的(de)(de)(de)(de)(de)剛度增大，同時(shi)(shi)又受到(dao)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)輥(gun)(gun)和平(ping)整輥(gun)(gun)的(de)(de)(de)(de)(de)約束，其自(zi)由度就減小。以(yi)(yi)(yi)上這(zhe)些都可以(yi)(yi)(yi)有效(xiao)地防(fang)止局部(bu)(bu)(bu)收縮和型(xing)(xing)鋼(gang)的(de)(de)(de)(de)(de)扭轉(zhuan)，從(cong)而(er)對(dui)保證瓦楞(leng)(leng)形(xing)(xing)(xing)板(ban)(ban)的(de)(de)(de)(de)(de)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)及質(zhi)(zhi)量起(qi)(qi)(qi)到(dao)有效(xiao)的(de)(de)(de)(de)(de)保障(zhang)作用。瓦楞(leng)(leng)形(xing)(xing)(xing)板(ban)(ban)橫向(xiang)波(bo)(bo)紋(wen)沖(chong)壓輥(gun)(gun)的(de)(de)(de)(de)(de)示(shi)意圖(tu)，見(jian)圖(tu)5-44。

 沖壓成型(xing)輥也應做成組合式(shi)輥子(zi)，即由多(duo)輥片疊加組合而成。這種形式(shi)的輥子(zi)便(bian)于加工和(he)維護(hu)，調整(zheng)使用方便(bian)。
