Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipe sealing, in particular to a circular sealing device for the end of a stainless steel pipe. Background Art

[0002] Stainless steel pipe end sealing typically involves welding a metal disc to the pipe, creating a sealed connection. This method is suitable for applications involving high temperatures, high pressures, and corrosive media, offering reliable sealing and high strength.

[0003] The existing referenceable announcement number is: CN204449697U Chinese utility model patent, which discloses a pipe sealing device for a thin-walled stainless steel pipe production line, wherein a lower support roller and an upper pressure roller are installed on the support, the lower support roller is a rubber roller, and a central pipe pressing portion and a side pipe pressing portion are formed in the middle of the upper pressure roller, the two side pipe pressing portions are symmetrically formed on the two sides of the central pipe pressing portion, the outer surface of the side pipe pressing portion is annular, the central pipe pressing portion is pressed on the upper end of the rolled pipe, and the two side pipe pressing portions are pressed on the two sides of the rolled pipe; the eight-shaped gate support rod is fixed on the support, the eight-shaped gate is fixed on the support rod, the rolled pipe first passes through the eight-shaped gate and then enters between the support roller and the upper pressure roller, the welding head is fixed on the support, the welding head faces the upper end of the rolled pipe, and the blank pipe after welding by the welding head is clamped between the upper traction conveyor belt and the lower traction conveyor belt. The plate rolled into a pipe is first clamped by an eight-shaped door, and then pressed by a pressing wheel to ensure that the upper end of the rolled pipe is closed, thereby ensuring that the stainless steel pipe has good sealing performance during welding.

[0004] The existing sealing equipment cannot keep the center of the disc and the axis of the stainless steel tube in the same straight line when in use. During welding, the disc may not be able to completely cover the end of the stainless steel tube, affecting the sealing effect after welding. The stainless steel tube is cylindrical and needs to be rotated during welding to weld the outer edge of the stainless steel tube and the outer edge of the disc. Since the position of the disc needs to be restricted during welding, it is very inconvenient to weld. Utility Model Content

[0015] Compared with the prior art, the present invention provides a circular sealing device for the end of a stainless steel pipe, which has the following beneficial effects:

[0016] 1. The utility model adopts the setting of a spherical magnet, which is annularly mounted on the front side of the base with the center of the base as the reference, and a rotatable connection is formed between the spherical magnet and the base, and the surface of the limit plate is provided with an open hole structure which is engaged with the spherical magnet.
