Background technology
Primary Ioops main pipeline belongs to core one-level parts, primarily of parts compositions such as straight tube, elbow, inclined pipe, joints, wherein straight tube bevel welding inclined pipe wherein makes one of difficult point, and mainly because straight tube external diameter is large, wall thickness is large, weld seam is long and large, after welding, distortion seriously.
General heavy caliber straight tube is when bevel welding inclined pipe, jack can be used to support at endoporus, because the push rod on thousand tops is that carbon steel is made, and the contact area of push rod and product endoporus is little, so there will be the shortcoming such as fineness, generation iron preventing pollution, support zone skidding, operation inconvenience of destroy product endoporus.Being out of shape serious shortcoming except methods such as conventional prestrain method, weld preheating, hammering method, small area analysis layering weldering, control interlayer temperatures for solving, also needing design one at straight tube endoporus supporting tool to reduce welding deformation.
Summary of the invention
The purpose of this utility model to solve the problems of the technologies described above.
The purpose of this utility model is achieved in that the frock reducing Internal Hole Deformation after core pipeline welding, comprise inclined pipe, supporting tool, the lower end of inclined pipe is provided with straight tube, it is characterized in that: the two pieces supporting tool arranged before and after described straight tube entrance is provided with, two pieces supporting tool is mutually 90 degree of layouts; Supporting tool is made up of upper back-up block, upper back-up ring, support bar A, steel pipe, oil cylinder, lower back-up ring, support bar B, lower support block, the top of steel pipe is provided with back-up ring, the bottom of steel pipe is provided with lower back-up ring, top in steel pipe is provided with support bar A, support bar A upper end is connected with upper back-up block through after upper back-up ring, the lower end of support bar A is disposed with oil cylinder, support bar B downwards, and support bar B lower end is connected with lower support block through after lower back-up ring.
Described upper back-up block, support bar A, oil cylinder, support bar B, lower support block are on same center line.
Described outer ring, steel pipe bottom is provided with U-type groove, and the opening size of U-type groove is greater than the joint dimension of oil cylinder.
Described upper back-up block is sector structure, and the arc radius of upper back-up block outer ring is less than the radius of straight tube.
Described lower support block is sector structure, and the arc radius of lower support block outer ring is less than the radius of straight tube.
The utility model execute-in-place is simple and convenient, demolition convenient, can repeatedly use, prevent supporting tool from skidding, the fineness of destroy product endoporus can be avoided, improve production efficiency, efficiently reduce the Internal Hole Deformation amount of large diameter pipeline welding point, apply and there is good economic and social benefit.
