Supporting tool in thin-wall pipe

Abstract

The invention discloses a supporting tool in a thin-wall pipe. The supporting tool comprises an upper supporting plate and a corresponding lower supporting plate. The center of the upper supporting plate and the center of the lower supporting plate are connected with a lead screw through a left thread and / or a right thread, upper hinges are arranged on the edge of the upper supporting plate at equal central angles, and the upper hinges are hinged to upper supporting rods. Lower hinges are correspondingly arranged on the edge of the lower supporting plate at equal central angles, the lower hinges are hinged to lower supporting rods, and the upper supporting rods and the lower supporting rods are hinged through hinges. A locking nut is arranged between the upper supporting plate and the leadscrew, and a locking nut is arranged between the lower supporting plate and the lead screw. The supporting tool is provided with a fixing structure. The supporting tool adapts to the sizes of different pipe diameters, the roundness of the pipe is kept, grooves meeting standard requirements can be machined conveniently, the problem that when grooves are machined in the stainless steel thin-wall pipe, the pipe diameters deform is solved, the supporting tool is convenient to dismount and mount and easy to operate, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of steel pipe structural parts, in particular to a support tool in a thin-walled pipe. Background technique [0002] The piping system of chemical tankers is mostly made of stainless steel, and the wall thickness of the pipe is usually thin (mostly less than 4mm). The pipe and the flange are welded in the form of butt joint. Before welding, both ends of the pipe need to be grooved with a beveling machine. Due to the thin pipe wall, the diameter of the pipe is easily deformed when the beveling machine clamps the pipe, and the processed bevel size and shape have large deviations, resulting in uneven joints during the next process of assembly and welding, which affects the assembly quality. Contents of the invention [0003] The purpose of the present invention is to provide a thin-walled pipe inner support tool, which can finely adjust the size of the outer support ring formed by the support tool, adapt to t...

Problems solved by technology

[0003] The purpose of the present invention is to provide a thin-walled pipe inner support tool, which can finely adjust the size of the outer support ring formed by the support tool, adapt to the size of different pipe diameters, maintain the roundness of the pipe, and facilitate processing to meet the standard requirements. The groove solves the problem of pipe diameter deformation when processing grooves for stainless steel thin-walled pipes. It is easy to disassemble and operate, and is conducive to improving work efficiency. The support tooling can be finely adjusted according to the pipe diameter.
