    • The present invention refers to a method for obtaining an opening (8) in a hollow-body member (3) having a longitudinal extension and a cavity (6), and to a hollow-body member (3) provided with one or more openings (8, 9) obtained with the above-mentioned method, which includes the following phases: a. predisposing a holding die (12) including a seat (17) countershaped with respect with said hollow-body member (3) and an ejection channel (13) having a first end (18) communicating with said seat (17) and a second ejection end (19); b. inserting and positioning the hollow-body member (3) in the seat (17) so that said first end (18) is arranged in correspondence with a wall portion of said hollow-body member (3) on which to obtain an opening (8); c. generating a progressively increasing pressure inside said cavity (6) sufficient to deform said wall portion (16) to a point of detaching it from the hollow-body member (3) to form said opening (8), and expelling the wall portion (16) along the ejection channel (13).
    • 本发明涉及一种在具有纵向延伸部和空腔(6)的中空体部件(3)中获得开口(8)的方法,以及设置有一个或多个开口 (8,9),其包括以下步骤:a。 倾向于包括相对于所述中空本体构件(3)重合的座(17)和具有与所述座(17)连通的第一端(18)的弹出通道(13)的保持模(12) 结束(19); b。 将所述中空体构件(3)插入并定位在所述座(17)中,使得所述第一端(18)与所述中空体构件(3)的壁部相对应地设置,在所述中空体构件 ); C。 在所述空腔(6)内产生足以使所述壁部分(16)变形到将其从中空本体构件(3)拆下以形成所述开口(8)的点的逐渐增加的压力,并且排出所述壁部分 )沿着喷射通道(13)。
