阅读说明：本技术 筛制造方法 (Screen manufacturing method ) 是由 W.布雷特施奈德 I.考尔 M.谢德勒 R.伯格 J.亚伯拉罕 于 2020-02-13 设计创作，主要内容包括：在一种用于制造具有多个型材棒(12)的筒形的筛装置(10)的方法中,所述型材棒(12)彼此平行并且平行于筒轴线地插入设置在多个间隔棒固持环(14)的内侧面上的边缘敞开的凹部(16)中,所述多个棒固持环分别在垂直于筒轴线的平面中围绕筒轴线延伸并且沿轴向相互间隔开,所述凹部在其形状方面至少基本上与型材棒(12)的棒脚(18)的形状互补然而首先还略微大于型材棒的棒脚,并且棒固持环(14)的内径和外径通过径向从外部作用的力被永久减小,直至型材棒(12)和棒固持环(14)的凹部(16)之间形状配合。在此,通过分布在棒固持环(14)的圆周上的压爪(20)施加径向从外部作用的力,所述压爪分别设有多个沿周向和径向延伸的用于容纳相应的棒固持环(14)的槽(22),所述槽(22)中的分别仅一部分在相应的压制过程期间作为压槽用于直接径向压制相关的棒固持环(14),并且其他的槽(22)仅用作导槽,通过所述导槽防止相关的棒固持环(14)轴向偏移,和/或也可以使用预制有波形外轮廓的棒固持环(14),该棒固持环在其波形外轮廓(28)上通过径向从外部作用的力被径向压制。(In a method for producing a cylindrical screen device (10) having a plurality of profile bars (12), which profile bars (12) are inserted parallel to one another and parallel to a cylinder axis into open-edged recesses (16) which are arranged on the inner side of a plurality of spacer bar retaining rings (14) which extend around the cylinder axis in a plane perpendicular to the cylinder axis and are spaced apart from one another in the axial direction, the recesses are at least substantially complementary in terms of their shape to the shape of the legs (18) of the profile bars (12) but are at first also slightly larger than the legs of the profile bars, and the inner and outer diameters of the bar retaining rings (14) are permanently reduced by a force acting radially from the outside until there is a form fit between the recesses (16) of the profile bars (12) and the bar retaining rings (14). Here, the forces acting radially from the outside are exerted by pressure claws (20) distributed over the circumference of the rod holding ring (14), which are each provided with a plurality of grooves (22) extending in the circumferential direction and radially for receiving the respective rod holding ring (14), only a part of the grooves (22) being used as pressure grooves during the respective pressing process for directly pressing the respective rod holding ring (14) radially, and the other grooves (22) serving only as guide grooves, by means of which the respective rod holding ring (14) is prevented from being axially offset, and/or it is also possible to use a rod holding ring (14) which is pre-profiled with a wave-shaped outer contour and is pressed radially on its wave-shaped outer contour (28) by the forces acting radially from the outside.)
