Problems solved by technology
Because the steel pipe is limited by the production equipment, the welded pipe is not properly formed, and the ellipticity of the produced steel pipe often exceeds the standard. It is very difficult to ensure the cylindricity of the steel pipe end.
At present, the cylindricity of the steel pipe end is generally guaranteed by frequently correcting the forming mold, but the cost of correcting the forming mold is high and takes a long time, which affects the production efficiency, leads to the decrease of the enterprise's income and increases the investment

Embodiment Construction
[0020] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.
[0021] Such as figure 1 and figure 2 As shown, a steel pipe end rounding machine includes a rectangular frame 1, a mounting lifting seat 2 placed in the rectangular frame 1, connecting the rectangular frame 1 and the mounting lifting seat 2 and for the up and down movement of the mounting lifting seat 2 The electric push rod 3 that improves power is positioned at the jack mounting seat 4 that the front end of the rectangular vehicle frame 1 links to each other with the installation of the lifting seat 2, and a buffer device 5 is also connected between the rectangular vehicle frame 1 and the installation of the lifting seat 2.
[0022] The front and rear sides of the rectangular frame 1 are respectively provided with reinforcing ribs 11 parallel to each other, and a transverse partition 12 is connected between the two parallel reinforcing ribs 11,...

The invention relates to a roundness correction machine for the end of a steel tube, and belongs to the technical field of production line equipment for the steel tube. The roundness correction machine for the end of the steel tube comprises a rectangular frame, an installation lifting base arranged in the rectangular frame, an electric push rod connected with the rectangular frame and the installation lifting base and providing power for the vertical motion of the installation lifting base, and a jack installation base located at the front end of the rectangular frame and connected with the installation lifting base. A buffer device is connected between the rectangular frame and the installation lifting base. A rounding lower die is installed on the bottom of the jack installation base, a jack is installed in the jack installation base, and a rounding upper die is installed on the top of a piston of the jack. When the roundness correction machine is in use, the jack extends into the steel tube together with the rounding upper die and the rounding lower die, and then the roundness of the steel tube is corrected under the acting force of the jack. The roundness correction machine is simple in structure, easy to implement and easy and convenient to use. The upper die and the lower die extend into the steel tube, the ovality of the end of the steel tube is corrected by expanding through the jack, and therefore the production efficiency is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of steel pipe production line equipment, in particular to a steel pipe end rounding machine. Background technique [0002] With the development of society, steel pipe users have higher and higher requirements for the cylindricity of the steel pipe end, because the steel pipe needs to ensure the cylindricity of the steel pipe end during subsequent processing or use. Because the steel pipe is limited by the production equipment, the welded pipe is not properly formed, and the ellipticity of the produced steel pipe often exceeds the standard. It is very difficult to ensure the cylindricity of the steel pipe end. At present, the cylindricity of the pipe end of the steel pipe is generally guaranteed by frequently correcting the forming mold, but the cost of correcting the forming mold is high and takes a long time, which affects the production efficiency, reduces the enterprise's income, and increases the investm...
