Hydraulic flange of nickel alloy pipe

Abstract

The invention discloses a hydraulic flange of a nickel alloy pipe. The flange comprises a base, a mounting base, a hydraulic cylinder, a hydraulic column, a flanging die, a pipe body, a box body, a mounting assembly and a clamping device, wherein the output end of the hydraulic cylinder is connected with the hydraulic column, the other end of the hydraulic column is connected with the flanging diethrough the mounting assembly, and the box body is connected with the pipe body through the clamping device; a first connecting piece is connected with one end of the hydraulic column, and a second connecting piece is connected with the flanging die; two first connecting rods are arranged, are correspondingly connected with second connecting rods in a sleeve mode and are connected to the second connecting rods in a sliding mode, first springs sleeve the second connecting rods, fixing blocks are arranged on the inner walls of the other ends, facing the first connecting piece, of the first connecting rods, and through holes matched with the fixing blocks are formed in the second connecting piece. The flange has the advantages of being capable of facilitating replacement and maintenance of the flanging die at the later stage and good in firm stability during clamping and fixing of a pipe.

Description

technical field [0001] The invention relates to the technical field of hydraulic flanging, in particular to a hydraulic flanging of a nickel alloy tube. Background technique [0002] Copper-nickel alloy pipe is an internationally recognized copper alloy with excellent seawater corrosion resistance. Copper-nickel alloy pipe (B10 pipe) has excellent seawater impact corrosion resistance, low corrosion temperature sensitivity, light weight, and excellent corrosion resistance. It is favored by ship designers because of its pollution performance. Copper-nickel alloy pipes have been widely used in seawater piping systems of ships, and have initially solved the corrosion problem of straight pipe sections in seawater piping systems. , prone to breakage and breakage. In practical applications, forming elbows or forming flange welding methods are mostly used to realize the connection between copper-nickel alloy pipes. The welding construction workload is large, and the welding seam i...
