Problems solved by technology

The disadvantage is that the support ring or the support column is difficult to reuse due to reasons such as dismantling and easy damage; this support method only closes the curvature of the cylinder once to support the circle, and it is difficult to adjust the curvature locally to achieve accurate support of the ellipse Spend

Embodiment Construction

[0012] Such as figure 1 A kind of thin-walled cylinder ring seam group timing internal support circle tooling, which includes shell backing plate 1, support arc plate 2, rib plate 3 and locking device, shell backing plate 1, support arc plate 2 and rib The plate 3 is welded together, and the inner radius curvature of the shell backing plate 1 and the cylinder body 5 drawing requirements tends to be consistent; the supporting arc plate 2 and the shell backing plate 1 are welded to rigidly fix the shell backing plate 1 The role; the ribs 3 are connected by a locking device.

[0013] The locking device is flexibly connected with two adjacent ribs 3 through positive and negative threaded buttons 4 . The two ends of the positive and negative threaded buttons are respectively connected with the rib plate 3, which is threaded connection; wherein, there is a circular perforation in the middle of the positive and negative threaded button 4, and a section of bar is added to rotate and ...

Abstract

The invention discloses an inner circular expanding tool in thin-wall cylinder circular seam pairing. The tool comprises a shell cushion plate, a support arc plate, rib plates and a locking device; the shell cushion plate, the support arc plate and the rib plates are welded and connected as a whole; the rib plates are connected through the locking device; and the locking device is movably connected with two adjacent rib plates through forward and reverse screw buckles. The tool is simple in structure, is adopted without influencing such work as welding of circular seams, is convenient in installation and disassembly, has such advantages as low cost and easiness in operation, is free of influencing the welding work of cylinder circular seams, improves the working efficiency, and effectively prevents such quality problems as easiness in deformation and cylinder waist collapse in welding of the circular seams.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and in particular relates to an internal circular support tool for aligning circular seams of a thin-walled cylinder. Background technique [0002] In mechanical manufacturing, especially in the petrochemical container industry, there are many thin-walled cylindrical cylinders, and the main manufacturing process of rolling is particularly important. At present, when assembling and welding the circumferential joint between the cylinder and the cylinder, it is mainly to install a support column or a support ring on the inner wall of the cylinder to prevent the circular seam assembly of the cylinder from reducing misalignment and welding to reduce deformation. The disadvantage is that the support ring or the support column is difficult to reuse due to reasons such as dismantling and easy damage; this support method only closes to the curvature of the cylinder once to support the circle, and it is...
