SU25036A1 - Metal core to fill the tubes before they are bent - Google Patents

Description

The proposed metal core for filling the pipes before their bending is made in the form of two or several correspondingly shaped plates, laid into the pipe together with a spring strip laid between them and made of a more flexible material, 4% vi bend pipe.

In FIG. 1 shows a side view of a pipe with a core embedded in it; FIG. 2 is a top view of a pipe with a core embedded in it; FIG. 3 is a view of it in cross section; FIG. 4 is a schematic of a pipe bending tool.

The proposed metal core consists of gisyx plates 2, made in the shape of a segment of a bendable pipe 1 and a spring strip 3 laid between plates 2, at 4t, vi plates 2 are made of a more flexible material, v material of a bendable pipe.

Before bending pipe 1 into it

the core is laid and its end is fixed with clamp 5 on template 4. The tube is bent using an appropriately shaped pressure element 6. When removing the core from the tube, strip 3 is pre-removed, after which it is difficult to remove the plates 2. The proposed core may not be only from two, but also from several correspondingly profiled plates, which are laid into the pipe before it is bent in a manner similar to that described above.

The subject matter of the invention.

A metal core for filling the pipes before they are bent, characterized in that 41Q is made up of two or more appropriately designed plates 2 of a more flexible material, h & U1 the pipe itself, with a spring strip 3 between them.
