第三(san)架(jia)成(cheng)(cheng)型(xing)(xing)輥(gun)輥(gun)形(xing)(xing)圖(tu)(tu)和(he)孔形(xing)(xing)圖(tu)(tu)，見(jian)圖(tu)(tu)5-43.第三(san)架(jia)成(cheng)(cheng)型(xing)(xing)輥(gun)應(ying)是由多片輥(gun)片疊加(jia)組合(he)而成(cheng)(cheng)的(de)組合(he)輥(gun)，輥(gun)片的(de)水平(ping)段(duan)和(he)圓(yuan)(yuan)弧(hu)段(duan)采取與(yu)板(ban)材(cai)接(jie)觸的(de)方(fang)(fang)式，而傾斜段(duan)則采取與(yu)板(ban)材(cai)不接(jie)觸的(de)方(fang)(fang)式，為的(de)是減(jian)少(shao)成(cheng)(cheng)型(xing)(xing)表面的(de)擦劃(hua)傷，此外，如此結構也將便于成(cheng)(cheng)型(xing)(xing)輥(gun)的(de)加(jia)工和(he)隨后的(de)使用(yong)與(yu)維護等。上(shang)、下輥(gun)斜角采取圓(yuan)(yuan)弧(hu)過(guo)(guo)渡，一般情況下，圓(yuan)(yuan)弧(hu)的(de)直(zhi)徑(jing)應(ying)大于板(ban)厚，所以圖(tu)(tu)5-43所示的(de)第三(san)架(jia)上(shang)、下輥(gun)斜角的(de)圓(yuan)(yuan)弧(hu)過(guo)(guo)渡直(zhi)徑(jing)為2.0mm,見(jian)圖(tu)(tu)5-43局(ju)部放大圖(tu)(tu)。
3. 縱向(xiang)波紋的成型
縱向波(bo)紋的成(cheng)(cheng)型(xing)(xing)(xing)是(shi)在橫向波(bo)紋成(cheng)(cheng)型(xing)(xing)(xing)之后的橫向波(bo)紋上成(cheng)(cheng)型(xing)(xing)(xing)的。所以在已(yi)成(cheng)(cheng)型(xing)(xing)(xing)的波(bo)紋上再成(cheng)(cheng)型(xing)(xing)(xing)縱向波(bo)紋是(shi)有難(nan)度(du)的。其難(nan)度(du)主要表現為，可能破壞已(yi)成(cheng)(cheng)型(xing)(xing)(xing)的橫向波(bo)紋，而且縱向波(bo)紋也成(cheng)(cheng)型(xing)(xing)(xing)不好。選用何種方式(shi)成(cheng)(cheng)型(xing)(xing)(xing)就成(cheng)(cheng)為縱向波(bo)紋成(cheng)(cheng)型(xing)(xing)(xing)的關(guan)鍵(jian)。
沖(chong)壓(ya)(ya)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)輥(gun)(gun)(gun)就是(shi)在(zai)一對(dui)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)輥(gun)(gun)(gun)上(shang)，按工藝和(he)產品的(de)(de)(de)要求，在(zai)要面上(shang)間隙分(fen)(fen)布著凸(tu)起(qi)和(he)凹(ao)陷的(de)(de)(de)部分(fen)(fen)，用(yong)于壓(ya)(ya)制成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)瓦(wa)楞(leng)形(xing)板(ban)(ban)的(de)(de)(de)縱向波紋(wen)(wen)，同(tong)時(shi)又不能損(sun)壞已(yi)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)的(de)(de)(de)橫(heng)(heng)向梯形(xing)波紋(wen)(wen)，縱向波紋(wen)(wen)尺寸(cun)圖及(ji)(ji)實物圖片，見圖5-40和(he)圖5-41。之所以(yi)(yi)(yi)將沖(chong)壓(ya)(ya)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)輥(gun)(gun)(gun)置于橫(heng)(heng)向波紋(wen)(wen)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)輥(gun)(gun)(gun)后、平(ping)整(zheng)(zheng)輥(gun)(gun)(gun)前，是(shi)為(wei)了保證瓦(wa)楞(leng)形(xing)板(ban)(ban)的(de)(de)(de)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)過程的(de)(de)(de)穩定和(he)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)質量(liang)。可(ke)以(yi)(yi)(yi)想象，在(zai)沒(mei)有橫(heng)(heng)向波紋(wen)(wen)的(de)(de)(de)平(ping)板(ban)(ban)帶(dai)材上(shang)沖(chong)壓(ya)(ya)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)凸(tu)起(qi)和(he)凹(ao)陷型(xing)(xing)(xing)(xing)材，由(you)(you)于自由(you)(you)度大沒(mei)有約(yue)束力，沖(chong)壓(ya)(ya)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)會(hui)造(zao)成(cheng)(cheng)(cheng)(cheng)(cheng)坯料(liao)局部收縮，產生皺(zhou)折及(ji)(ji)其(qi)他缺陷，影響成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)質量(liang)和(he)成(cheng)(cheng)(cheng)(cheng)(cheng)品的(de)(de)(de)尺寸(cun)。另外，瓦(wa)楞(leng)形(xing)板(ban)(ban)型(xing)(xing)(xing)(xing)鋼截面受材料(liao)內部殘余應力作用(yong)，很容易產生扭(niu)轉，這也會(hui)影響成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)過程的(de)(de)(de)穩定性。但在(zai)瓦(wa)楞(leng)形(xing)板(ban)(ban)橫(heng)(heng)向波紋(wen)(wen)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)輥(gun)(gun)(gun)后、平(ping)整(zheng)(zheng)輥(gun)(gun)(gun)前，再用(yong)沖(chong)壓(ya)(ya)輥(gun)(gun)(gun)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)其(qi)縱向波紋(wen)(wen)，此(ci)時(shi)，已(yi)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)的(de)(de)(de)橫(heng)(heng)向波紋(wen)(wen)使瓦(wa)楞(leng)形(xing)板(ban)(ban)的(de)(de)(de)剛度增(zeng)大，同(tong)時(shi)又受到成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)輥(gun)(gun)(gun)和(he)平(ping)整(zheng)(zheng)輥(gun)(gun)(gun)的(de)(de)(de)約(yue)束，其(qi)自由(you)(you)度就減(jian)小。以(yi)(yi)(yi)上(shang)這些都可(ke)以(yi)(yi)(yi)有效(xiao)地(di)防止局部收縮和(he)型(xing)(xing)(xing)(xing)鋼的(de)(de)(de)扭(niu)轉，從而(er)對(dui)保證瓦(wa)楞(leng)形(xing)板(ban)(ban)的(de)(de)(de)成(cheng)(cheng)(cheng)(cheng)(cheng)型(xing)(xing)(xing)(xing)及(ji)(ji)質量(liang)起(qi)到有效(xiao)的(de)(de)(de)保障作用(yong)。瓦(wa)楞(leng)形(xing)板(ban)(ban)橫(heng)(heng)向波紋(wen)(wen)沖(chong)壓(ya)(ya)輥(gun)(gun)(gun)的(de)(de)(de)示意圖，見圖5-44。
沖壓成(cheng)型輥也應(ying)做成(cheng)組合(he)式輥子，即由多輥片疊加(jia)組合(he)而(er)成(cheng)。這(zhe)種形式的輥子便于加(jia)工和維護，調(diao)整使用方便。
