Detailed Description
Specific embodiments of the present invention will be described in detail hereinafter by way of illustration and not limitation with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of a flange for welding a cylinder according to an embodiment of the present invention. Fig. 2 is an enlarged partial cross-sectional view of the flange for welding the can shown in fig. 1.
As shown in fig. 1-2, the flange of the present embodiment may include a flange body 10, a cylinder attachment groove 12 formed at an outer periphery of a central hole 11 of the flange body 10, a welding protrusion 13 formed at an outer periphery of the cylinder attachment groove 12, and a welding groove 14 formed at an outer periphery of the welding protrusion 13.
The flange body 10 may have, for example, a circular shape as shown in the drawings or other shapes such as a square shape or the like. A central aperture 11 is formed in the centre of the flange and may be circular or of any other suitable shape. A coupling groove 12 is formed at the outer periphery of the central hole 11, that is, immediately adjacent to the central hole 11, the coupling groove 12 being used to set a cylinder 15 to be welded (see fig. 3). The coupling groove substantially conforms to the cross-sectional shape of the can body, for example when the can body is a hollow cylinder, the coupling groove 12 is formed in a circular ring shape having a diameter substantially conforming to the can body so that the can body can be properly fitted in the coupling groove 12 for welding. When the cylinder is square, the coupling groove 12 may be formed in a square shape. The depth of the connecting groove 12 may be set according to the requirements of the cylinder and the particular weld, for example 5mm-40 mm.
A welding projection 13 is formed on the outer periphery of the coupling groove, and has a shape substantially corresponding to the coupling groove, and may be, for example, a ring shape, and surrounds the coupling groove 12. And a welding groove 14 formed at the outer circumference of the welding protrusion 13. The welding recess 14 is surrounded by a welding projection 13, the depth of which may suitably be set, for example, 3-10mm, for example 4-8mm, etc. Generally, there are a lateral tension and a longitudinal tension when welding with the can using the welding protrusions. However, due to the arrangement of the welding groove 14, transverse tensile force in the welding process can be cut off, and meanwhile, longitudinal tensile force is basically balanced due to the support between the flange plate body and the cylinder body, so that the whole tensile deformation is reduced, and the sealing requirement of a vacuum chamber and the like can be met. The cross-sectional shape of the welding groove 14 may be, for example, a rectangle, and the width thereof may be set as appropriate as long as welding can be performed to intercept the lateral tensile force.
Fig. 3 is a schematic view of a flange for welding a can after being combined with the can according to an embodiment of the present invention. Referring to fig. 3, the cylinder may be disposed in the coupling groove 12 and then welded using the welding protrusion 13. After welding a weld 16 is formed and the weld recesses 14 serve as spacers, wherein the diameter of the cylinder 15 may be 400mm-1600mm, for example 500mm-1500mm, 1000mm, etc. After welding, the cylinder flange of the utility model is formed.
The utility model discloses the technique has mainly solved ring flange and barrel and has taken over the welding time, and the barrel is vertical by transversely becoming the tensile deformation problem of welding of flange through setting up the welding recess with the tensile force, and vertical pulling force supports with the ring flange body and offsets, reduces tensile deformation, can satisfy the sealed requirement of vacuum chamber.
While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It will be understood by those skilled in the art that variations and modifications of the embodiments of the present invention can be made without departing from the scope and spirit of the invention.
