In view of the above, the present invention aims to provide a high strength profiled pipe with high strength and stability and less deformation.
In order to solve the technical problems, the technical scheme of the utility model is as follows:
a high-strength special pipe is characterized in that a raw material steel plate is mechanically bent into a pipe shape, then the pipe shape is formed by extrusion through a die, and the pipe shape is welded to obtain an outer pipe body, and a support pipe frame which is formed inside the outer pipe body and is integrally formed with the outer pipe body; the outer pipe body comprises an arc-shaped part, a first bottom support part and a second bottom support part, wherein the first bottom support part is positioned at one end of the arc-shaped part and is bent inwards; the support pipe support is the triangular tube, including first inclined plane portion, with the second inclined plane portion that first inclined plane portion degree is the same the first butt face of the lower extreme incurvature of first inclined plane portion the second butt face that the lower extreme incurvature of second inclined plane portion just was on same horizontal plane with first butt face.
Preferably, the bent portions of the first and second inclined surface portions abut against a midpoint of the arc portion.
Preferably, the first contact surface and the second shoe portion are integrally formed.
Preferably, the second contact surface is formed integrally with the first shoe portion.
Preferably, the weld of the outer tube body is located on the first base part or the second base part.
The technical effects of the utility model are mainly reflected in the following aspects: the supporting pipe frame integrally formed in the outer pipe body is high in strength and stability of the section bar and not prone to deformation.

In the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin connecting manner, or the like, which is commonly used in the prior art, and therefore, details thereof are not described in the present embodiment.
Examples
A high-strength special pipe, as shown in figure 1-2, is composed of an outer pipe body 1 obtained by mechanically bending a raw material steel plate into a pipe shape, then extruding and forming through a die and welding, and a support pipe frame 2 formed inside the outer pipe body 1 and integrally formed with the outer pipe body 1; the outer tube body 1 comprises an arc-shaped part 11, a first bottom support part 12 which is positioned at one end of the arc-shaped part 11 and is bent inwards, and a second bottom support part 13 which is positioned at the other end of the arc-shaped part 11 and is bent inwards; the support pipe support 2 is a triangular pipe, and includes a first inclined plane portion 21, a second inclined plane portion 22 having the same degree as the first inclined plane portion 21, a first abutting surface 23 bent inward at the lower end of the first inclined plane portion 21, and a second abutting surface 24 bent inward at the lower end of the second inclined plane portion 22 and located on the same horizontal plane as the first abutting surface 23.
In this embodiment, the bending portions of the first inclined surface portion 21 and the second inclined surface portion 22 abut against the middle point of the arc portion 11, and effectively support the arc portion 11 to prevent it from being deformed under pressure.
In this embodiment, the first abutting surface 23 and the second base portion 13 are integrally formed, specifically, after the end of the second base portion 13 is bent upward, the second base portion is bent toward the first inclined surface portion 21 to obtain the first abutting surface 23, and finally the first abutting surface 23 and the second base portion 13 are pressed flat and attached to each other, so that the first abutting surface 23 is matched with the second base portion 13, and can bear the pressure transmitted by the arc portion 11 through the first inclined surface portion 21, thereby avoiding deformation.
In this embodiment, the second abutting surface 24 and the first base portion 12 are integrally formed, specifically, after the end of the first base portion 12 is bent upward, the end is bent toward the second inclined surface portion 22 to obtain the second abutting surface 24, and finally, the second abutting surface 24 and the first base portion 12 are pressed flat and attached to each other, so that the second abutting surface 24 is matched with the first base portion 12, and can bear the pressure transmitted by the arc portion 11 through the second inclined surface portion 22, thereby avoiding deformation.
In this embodiment, the welding seam of the outer tube 1 is located on the first bottom support portion 12 or the second bottom support portion 13, and in actual use, after the outer tube 1 is subjected to an extrusion force, the welding seam is not prone to crack, so that the outer tube 1 is not deformed.
The technical effects of the utility model are mainly reflected in the following aspects: the supporting pipe frame integrally formed in the outer pipe body is high in strength and stability of the section bar and not prone to deformation.
