Embodiment Construction

[0022] according to figure 1 , on this known pipe forming press 1 for a long time, the steel plate 3 is gradually formed or deformed into a grooved pipe 4, which is provided with a flange 2 on its longitudinal side (see image 3 ). Here, the steel sheet 3 rests on a lower rolling tool 6 with two spaced apart supports 5a, 5b, wherein the deformation force is applied by a liftable upper rolling tool 9, which It is designed as a curved blade 7 with a shaping tool 8 mounted on its protruding front end. The steel sheet 3 to be formed or deformed is guided by two side ejectors 10a, 10b, of which one ejector 10a can be displaced linearly and followed by the thrust required for the next forming step steel plate segment. Such as figure 1 As shown in c, the finished grooved tube 4 has a large notch or gap 11, which makes it difficult to weld into a closed longitudinal seam welded tube, such as figure 1 Shown by the dotted line in c.

Abstract

The method involves supplying a sheet panel (3) to a pipe forming press (1) in which the sheet panel is molded to a slot pipe through application of bending force, where the slot pipe is provided with longitudinal edges. The slot pipe is manufactured with an irregular blank mold while a small molding of the sheet panel is carried out in a bending stage caused at an inner side of the sheet panel. The manufactured slot pipe is removed through application of pressing force in smaller areas formed in the center, where the pressing force acts outwardly on the blank mold. An independent claim is also included for a device for manufacturing cylindrical slot pipes from thick sheet panels.

Description

technical field [0001] The invention relates to a method for the manufacture of grooved pipes from steel plates, in particular thick steel plates, wherein the steel plates are fed to a pipe forming press in which the steel plates are placed on a lower rolling tool and bent by applying Force, previously formed by the liftable upper rolling tool grooved tube, the grooved tube has a longitudinal edge, the longitudinal edge with a gap and the subsequent longitudinal welding seam opposite. The invention also relates to a device for carrying out the method. Background technique [0002] The methods used in practice for the production of pipes from steel sheets include the pipe forming press method, which is preceded by a deformation or bending step carried out on a pipe forming press. Tube forming or tube bending presses usually have in a basic frame a lower rolling tool consisting of two supporting bodies or bending bodies arranged side by side at a lateral distance, and an uppe...
