Abstract
The utility model relates to an oil cylinder, particularly relates to an oil cylinder cylinder-barrel flange and cylinder barrel welding structure, and aims to solve the technical problems that because of conventional butt welding between a cylinder-barrel flange and a cylinder barrel, air holes are easily caused on the bottom of a welding line, terrible influences are caused to the abrasion of a main oil seal of a piston, the service life of the piston seal is short, and the working life of the whole oil cylinder become short. The welding structure provided by the utility model comprises a cylinder barrel (1), and is characterized in that a flange is disposed on one end of the cylinder barrel (1), a stage (3) is disposed on the inner end of the cylinder barrel, a connecting head (4) which can be embedded into the stage is disposed on the inner end of the flange, and the cylinder barrel and the flange are fixed through welding.
Description
Technical field
The utility model relates to a kind of oil cylinder, especially relates to a kind of cylinder tube flange and cylinder barrel welding mechanism.
Background technique
At aspects such as existing mechanical transport, liftings, the application of oil cylinder has been a kind of universal phenomenon.The application area of hydraulic jack very extensively.Wherein the general flange size of these oil cylinders is far longer than cylinder barrel size, if use all-in-one-piece, so both wasted material, efficiency is very low again, therefore, welding technique between cylinder barrel flange and cylinder barrel is just arisen at the historic moment, but the cylinder barrel flange that picture is common and the welding of the docking between cylinder barrel, be easy to cause weld seam bottom pore, operation is below had a huge impact, and the wearing and tearing of the main oil sealing of piston are produced to extremely bad impact, cause the piston seal life-span very short, affected the operating life of whole oil cylinder.
Model utility content
The utility model is to provide a kind of cylinder tube flange and cylinder barrel welding mechanism, it is mainly the docking welding solving between the existing cylinder barrel flange of prior art and cylinder barrel, be easy to cause weld seam bottom pore, and the wearing and tearing of the main oil sealing of piston are produced to extremely bad impact, cause the piston seal life-span very short, the technical problem of the shorter grade of operating life of whole oil cylinder.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Cylinder tube flange of the present utility model and cylinder barrel welding mechanism, comprise cylinder barrel, and one section of described cylinder barrel is provided with flange, and the inner of cylinder barrel is provided with step, and the inner of flange is provided with the connecting head that can embed step, and cylinder barrel and flange are by being welded and fixed.It can be all-in-one-piece that cylinder barrel flange is connected with cylinder barrel, and as preferably, it is between welding, cylinder barrel cylinder barrel flange and cylinder barrel to be to weld by U-shaped weld seam that described cylinder barrel flange and cylinder barrel connect; Needed working strength while having guaranteed cylinder barrel work, has saved material, has improved work efficiency.
As preferably, on described connecting head, have U-shaped weld seam, the cylinder barrel of U-shaped weld seam top, the interior edge face of flange are all inclined-plane.Cylinder barrel flange and cylinder barrel welding bottom are U-shaped weld seams, directly U-shaped bottom R3 is directly processed on cylinder barrel flange, and the direct machining angle of cylinder barrel weld seam is the slope weld seam of 7.5 °, and at a little step of the inner processing of cylinder barrel cylinder barrel, then cylinder barrel flange and cylinder barrel dock, and weld; After cooling, roll boring, the weld seam bottom processing of weld seam bottom 2-3mm is removed, thereby realize the slitless connection of cylinder barrel flange and cylinder barrel
As preferably, the inclined-plane of described cylinder barrel is 6-9 ° in the angle of vertical plane.
Therefore, the utility model utilizes the advantage of cylinder barrel flange forge piece surplus, does not need to purchase in addition new material, therefore saves material, has reduced the scrappage of cylinder barrel; In weld seam bottom, be not easy to produce pore, the cylinder barrel assembly endoporus roughness level of rolling after boring processing is higher, in the working life of having improved the main oil sealing of piston, has avoided the inner roughness of cylinder barrel poor, thereby has prevented the wearing and tearing to the main oil sealing of piston, simple and reasonable for structure.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Component, position and numbering in figure: cylinder barrel 1, flange 2, step 3, connecting head 4, U-shaped weld seam 5, inclined-plane 6.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the cylinder tube flange that this is routine and cylinder barrel welding mechanism, as Fig. 1, comprise cylinder barrel 1, one section of cylinder barrel is provided with flange 2, and the inner of cylinder barrel is provided with step 3, and the inner of flange is provided with the connecting head 4 that can embed step, and cylinder barrel and flange are by being welded and fixed.As Fig. 2, on connecting head 4, have U-shaped weld seam 5, the cylinder barrel of U-shaped weld seam top, the interior edge face of flange are all inclined-plane 6.The inclined-plane of cylinder barrel is 7.5 ° in the angle of vertical plane.
During use, be encased in oil cylinder.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
