鋼波紋管液壓(ya)成形(xing)(xing)工藝的樞紐(niu)是階(jie)段的成形(xing)(xing)壓(ya)力和脹(zhang)形(xing)(xing)程(cheng)度,通過成形(xing)(xing)壓(ya)力來控制脹(zhang)形(xing)(xing)程(cheng)度,假如脹(zhang)形(xing)(xing)程(cheng)度較大(da),管材輕易破裂(lie),假如脹(zhang)形(xing)(xing)程(cheng)度太小,脹(zhang)形(xing)(xing)沒(mei)有起到軸向定(ding)位作用(yong),成型之后(hou)的波紋管波紋不齊,成品率比較低。
