不銹鋼(gang)瓦(wa)楞形(xing)板是(shi)不銹鋼(gang)寬幅型鋼(gang)的一種，由于(yu)其形(xing)狀如同頂(ding)上用瓦(wa)片鋪成(cheng)的行列(lie)隆(long)起(qi)部(bu)分(fen)，故稱為香蕉app免費視頻在線觀看:不銹鋼瓦楞(leng)形板，如圖5-37所示。

 人們過去常見(jian)的“瓦(wa)楞(leng)(leng)（形）板(ban)”大都(dou)是(shi)(shi)用普通低碳鋼，也就是(shi)(shi)非(fei)合金鋼材料(liao)制(zhi)成的（見(jian)圖(tu)5-38),還(huan)有用非(fei)金屬材料(liao)如石棉(mian)、塑料(liao)、紙板(ban)等(deng)制(zhi)成的瓦(wa)楞(leng)(leng)形板(ban)。這(zhe)些瓦(wa)楞(leng)(leng)形板(ban)主(zhu)(zhu)要(yao)用于建筑領(ling)域的屋頂材料(liao)、外墻材料(liao)和各種包裝箱體的外形材料(liao)和產品包裝箱、盒等(deng)，之(zhi)所以做成瓦(wa)楞(leng)(leng)形狀，主(zhu)(zhu)要(yao)目的是(shi)(shi)增加結構剛度和穩定(ding)性(xing)。因(yin)此，其尺(chi)寸精(jing)度和表面(mian)質(zhi)量要(yao)求(qiu)(qiu)及材質(zhi)要(yao)求(qiu)(qiu)都(dou)不(bu)是(shi)(shi)很高。

1. 不銹鋼瓦楞形板外形尺寸

 從圖5-37和(he)(he)圖5-39可(ke)以(yi)看出不(bu)(bu)銹(xiu)鋼瓦楞形(xing)(xing)(xing)板的(de)(de)(de)外表形(xing)(xing)(xing)狀(zhuang)(zhuang)是(shi)有規律(lv)、周期性變化的(de)(de)(de)，而(er)且彎曲(qu)深度較小、形(xing)(xing)(xing)狀(zhuang)(zhuang)單(dan)一，不(bu)(bu)僅有橫(heng)向波(bo)紋(wen)，而(er)且還(huan)有縱(zong)向波(bo)紋(wen)。所(suo)以(yi)說，其(qi)形(xing)(xing)(xing)狀(zhuang)(zhuang)既簡單(dan)又復雜，簡單(dan)是(shi)指形(xing)(xing)(xing)狀(zhuang)(zhuang)單(dan)一，有規律(lv)；復雜是(shi)指不(bu)(bu)僅有橫(heng)向波(bo)紋(wen)，而(er)且還(huan)有縱(zong)向波(bo)紋(wen)。這就(jiu)給不(bu)(bu)銹(xiu)鋼瓦楞形(xing)(xing)(xing)板的(de)(de)(de)成(cheng)型帶(dai)來(lai)不(bu)(bu)小的(de)(de)(de)難度，在(zai)成(cheng)型工藝(yi)上必須采取(qu)相應的(de)(de)(de)工藝(yi)措施和(he)(he)手(shou)段，方能(neng)保證(zheng)獲得要求的(de)(de)(de)外形(xing)(xing)(xing)尺寸和(he)(he)成(cheng)型質量(liang)。

 圖5-39是(shi)不(bu)(bu)銹(xiu)鋼瓦(wa)(wa)楞(leng)形(xing)板的(de)實物(wu)照(zhao)片，從圖片可以(yi)看出(chu)，不(bu)(bu)銹(xiu)鋼瓦(wa)(wa)楞(leng)形(xing)板的(de)外(wai)表和形(xing)狀是(shi)非常美觀(guan)、漂亮的(de)，具(ju)有較高的(de)觀(guan)賞性(xing)，如同工藝品(pin)、裝飾品(pin)。

 圖(tu)5-39不銹鋼瓦楞形板A-A截面尺寸，見(jian)圖(tu)5-40,B-B截面尺寸，見(jian)圖(tu)5-41。

 不銹鋼瓦楞(leng)形板成品實物斷面圖(tu)片，見圖(tu)5-40(b)和(he)圖(tu)5-41(b)。

 從圖5-40和圖5-41可(ke)以看出，不(bu)銹鋼(gang)瓦楞(leng)形(xing)板的斷(duan)面變化的規律是周期(qi)性(xing)的，斷(duan)面形(xing)狀是關(guan)于縱向中心線為對稱的型(xing)鋼(gang)，彎曲深度(du)較(jiao)淺，深度(du)僅有(you)7mm。
