Embodiment 1

[0035]A thin-walled plate cylinder fixed seam expansion device, the fixed seam expansion device mainly acts on the thin-walled and unclosed cylinder 4 (that is, the cylinder 4 with joints), and is used to expand the gap size of the welded joint , so as to accurately locate the position of the seam.

[0036] The thin-walled plate cylinder fixed seam expansion device includes a base body on which a telescopic synchronous gear 8, an upper expansion telescopic rod 6 and a lower expansion telescopic rod 14 are arranged, wherein the telescopic synchronous gear 8 can be wound around the base body. When the axis rotates, the upper expansion telescopic rod 6 and the lower expansion telescopic rod 14 can move back and forth along their respective length directions on the base body. The upper expansion telescopic rod 6 is connected with an upper telescopic synchronous rack 7, and the upper expansion telescopic rod 6 and the upper telescopic synchronous rack 7 move synchronously together;...

Embodiment 2

[0042] On the basis of the first embodiment, a universal ball 11 is provided on the outer end surface of the upper expansion telescopic rod 6 , and a universal ball 11 is provided on the outer end surface of the lower expansion telescopic rod 14 . When expanding the cylinder 4, the universal ball 11 on the upper expansion telescopic rod 6 and the universal ball 11 on the lower expansion telescopic rod 14 are all in contact with the inner wall of the cylinder 4, so that the thin-walled cylinder 4 does not need to be rotated when the cylinder 4 is rotated. Plate cylinder fixed seam expansion device.

[0043] Universal balls 11 are all arranged on the outer end faces of the upper expansion telescopic rod 6 and the outer end faces of the lower expansion telescopic rods 14. When expanding the joints of the cylinder body 4, the universal balls 11 directly contact the inner wall of the cylinder body 4; A universal ball 11 is arranged between the telescopic rod and the cylinder 4, so ...

Embodiment 3

[0045] On the basis of Embodiment 1 or Embodiment 2, one side of the base body is also connected with an installation seat 1 for installing the counter knife 3 , wherein the installation seat 1 is arranged on the side of the base body away from the cylinder body 4 to be processed. The mounting base 1 is connected with a seam knife 3, and the side of the seam knife 3 close to the cylinder body 4 to be processed is provided with an introduction seam knife 2, which is used for introducing the seam of the cylinder body 4 middle. Both the seam knife 3 and the imported seam knife 2 are made of high-hardness materials.

[0046] Preferably, the caulking knife 3 is arranged as a sandwich structure, and the trachea and cables of the expansion device are located in the interlayer of the caulking knife 3 .

[0047] One side of the base body is connected with a mounting base 1 for installing the seam knife 3, and the seam knife 3 is connected to the installation, and the seam knife 3 is c...

Abstract

The invention discloses a fixed seam expanding device and welding equipment for a thin-walled plate cylinder, belongs to cylinder welding equipment in the technical field of welding, and aims to provide the fixed seam expanding device for the thin-walled plate cylinder, so that a welding seam is expanded and the accurate positioning for the seam is facilitated. The technical scheme is that the fixed seam expanding device comprises a substrate, wherein a telescopic synchronous gear is arranged on the substrate; an upper expansion telescopic link is arranged above the telescopic synchronous gear, and an upper telescopic synchronous rack is connected onto the upper expansion telescopic link; a lower expansion telescopic link is arranged below the telescopic synchronous gear, and a lower telescopic synchronous rack is connected onto the lower expansion telescopic link; the upper telescopic synchronous rack and the lower telescopic synchronous rack are meshed with the telescopic synchronous gear by corresponding to the upper side and the lower side of the telescopic synchronous gear respectively. The fixed seam expanding device for the thin-walled plate cylinder is applicable to cylinder welding and used for expanding the welding seam.

Description

technical field [0001] The invention belongs to the field of welding technology, and relates to a cylindrical body welding equipment, in particular to a thin-walled plate cylindrical body fixed seam expansion device for expanding a cylinder rolled by steel plates and finding the position of the weld seam. Background technique [0002] At present, the more advanced cylinder manufacturing process in China is to roll the plate into a cylinder through a rolling machine and weld the weld seam through a welding machine. The process needs to first cut the plate into a suitable size, and then roll the plate into a cylindrical shape through U-pressing and rounding processes, then weld the seams, and then make a cylindrical product through the process of correcting the circle of the cylinder. [0003] In the prior art, after the plate is rolled by the previous rounding machine, an unclosed seam is provided in the circumferential direction of the cylinder, and the unclosed seam is weld...
