Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
Example one
As shown in fig. 1, the end welding reinforcing ring for the vacuum metal bellows comprises a ring body 1, wherein the ring body 1 is made of a metal material.
Two terminal surfaces of tourus 1 are annular plane 10 and two annular plane 10 are parallel to each other, have seted up an annular grooving 11 at tourus 1's outer wall, and annular grooving 11 cuts into the outer wall of tourus 1 into bellows welded connection portion 12 and pressure net ring welding portion 13, and the thickness of bellows welded connection portion 12 is less than the thickness of pressure net ring welding portion 13.
The outer width of the bellows weld joint 12 is equal to or slightly greater than the wall thickness of the metallic flexible bellows body. For example, the thickness is 0.1-0.2 mm.
Specifically, the annular cutting groove 11 of the present embodiment is a V-shaped groove.
Secondly, the inner wall of the torus 1 is a cylindrical hole. When the metal flexible corrugated pipe body is a cylindrical hole, the inner diameter of the external pipeline is equal to that of the metal flexible corrugated pipe body.
During welding, as shown in fig. 1 and 2, end faces of two ends of the metal flexible corrugated pipe body 2 are flattened, an annular plane 10 at one end of the annular body 1 close to the corrugated pipe welding connection portion 12 is attached to the flattened end face at one end of the metal flexible corrugated pipe body, the metal flexible corrugated pipe body and the corrugated pipe welding connection portion 12 are welded in the circumferential direction by a welding gun (the outer edges of the two are welded in the circumferential direction), the metal mesh sleeve 3 and the mesh pressing ring 4 sleeved on the metal mesh sleeve are welded in the circumferential direction, the outer end of the mesh pressing ring is welded in the outer end of the mesh pressing ring welding portion 13 (the outer edges of the two are welded in the circumferential direction), and finally an external pipe is welded on the other annular plane 10 of the annular body 1.
The annular cutting groove 11 is used for welding subareas, and meanwhile, the added annular body 1 can avoid the phenomena of poor welding quality and the like caused by one-point welding for many times; secondly, it can carry out the welding process of substep through increasing tourus 1 to improve welding efficiency (traditional external pipe, pressure net ring and bellows need fix a position and once weld together, inefficiency).
