Problems solved by technology

During operation, the radial position of the top pressure nut is adjusted by turning the double-headed stud, so that the ellipse roundness of the thin-walled nozzle is shaped, thus effectively solving the butt joint of the thin-walled and large-diameter nozzle due to the out-of-tolerance roundness Misalignment problem, and improve the efficiency of shaping

Embodiment Construction

[0034] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0035] Such as Figures 1 to 5 Shown is an embodiment of a thin-walled pipe orifice shaping tool of the present invention, including an annular ring 1, a number of studs 2 are connected to the outer edge of the annular ring 1 through thread fit, and the double-ended studs 2 are threaded. The head studs 2 are evenly distributed along the circumferential direction, and the end of the double-ended studs 2 away from the annular ring 1 is connected with a pressure nut 3 through thread fit; the thread fit between the double-ended studs 2 and the annular ring 1 is a right-hand thread and the thread fit between the double-ended stud 2 and the top pressure nut 3 is...

Abstract

The invention relates to the technical field of welding process equipment, and discloses a thin-wall pipe orifice shaping tool. The thin-wall pipe orifice shaping tool comprises an annular ring; the outer edge of the annular ring is connected with multiple studs through threaded fit; the studs are uniformly distributed in the peripheral direction; the ends, far from the annular ring, of the studsare connected with ejecting nuts through threaded fit; the threaded fit between the studs and the annular ring is right-threaded fit, and the threaded fit between the studs and the ejecting nuts is left-threaded fit; or the threaded fit between the studs and the annular ring is left-threaded fit, and the threaded fit between the studs and the ejecting nuts is right-threaded fit. The thin-wall pipeorifice shaping tool improves the shaping quality and efficiency.

Description

technical field [0001] The invention relates to the technical field of welding process equipment, in particular to a thin-wall nozzle shaping tool. Background technique [0002] Large thin-walled tubes are widely used in machinery, chemical and other industries. Large thin-walled pipes are usually made of carbon steel plates, alloy plates or stainless steel plates. The specific production process is to first cut the plates and then roll them. Thin-walled tubes: For long-length pipelines, it is usually necessary to make thin-walled tubes in sections, and then perform butt welding. [0003] However, due to factors such as rolling error and welding deformation in the manufacturing process of the above-mentioned thin-walled tube, the roundness error of the manufactured thin-walled tube will be relatively large. For thin-walled pipes with large roundness errors, the misalignment errors of the nozzles often exceed the standard during butt welding, which cannot meet the assembly ...
