Problems solved by technology

[0002] The extra-long oil pipe is an indispensable and important auxiliary part in the hydraulic transmission system. Its performance is closely related to the normal and efficient operation of the entire hydraulic system; Great obstacles to manufacturing
[0003] At present, the conventional processing technology for ultra-long oil pipes is blanking-bending-vertical welding-phosphating, but due to many characteristics of oil pipes (long length, many bends, irregular shapes, pipe weight) and other reasons, the product is in the During the welding process, it is necessary to use the crane to lift, move, and assist manual cooperation. On the one hand, the labor intensity of the workers is increased, and on the other hand, the welding efficiency is reduced. After the oil pipe is bent, the welding stability of the end flange is poor. There are hidden dangers in the welding quality; in addition, after welding, the oil pipe is not conducive to placement, and the frame installation efficiency is low. Due to the accumulation of fluid inside the bend of the oil pipe, the elbow is prone to rust and affects the internal cleanliness

Embodiment Construction

[0068] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0069] Such as figure 1 As shown, in the prior art, when the ultra-long oil pipe 8 is welded, the oil pipe 8 is first bent, and the oil pipe 8 is bent into an irregular shape with multiple bends, and one end of the oil pipe 8 is welded. After that, the oil pipe 8 is hoisted and transported by driving (not shown in the figure), with the end of the oil pipe 8 not welded to the flange facing down, the angle position of the oil pipe 8 is adjusted, and the angle position of the oil pipe 8 is clamped and fixed by various clamps 9 , prevent the oil pipe 8 from shaking and shifting during the welding process, which affects the welding accuracy, and then adjust the...

Abstract

The device comprises a base; a fixed flange seat and a rotating flange seat slide relatively on the base; a fixed flange and a rotating flange which directly facing each other are correspondingly mounted on the fixed flange seat and the rotating flange seat; and a rotating motor for driving the rotating flange to rotate is mounted on the rotating flange seat. The invention discloses a bending andwelding device for a super-long pipe flange. According to the super-long pipe flange bending and welding device, additional manual cooperation is not required, the workload of workers is reduced, thewelding efficiency is improved, the welding precision and the welding quality are guaranteed, in addition, an oil pipe in a straight pipe state can be phosphatized and cleaned conveniently, and rusting caused by the residual accumulated liquid in the oil pipe is prevented. The invention further discloses a machining technology for welding and then bending the ultra-long pipe flange.

Description

technical field [0001] The invention relates to the technical field of oil pipe processing, in particular to an ultra-long pipe flange elbow welding device and a processing technology. Background technique [0002] The extra-long oil pipe is an indispensable and important auxiliary part in the hydraulic transmission system. Its performance is closely related to the normal and efficient operation of the entire hydraulic system; Manufacturing is a big obstacle. [0003] At present, the conventional processing technology for ultra-long oil pipes is blanking-bending-vertical welding-phosphating, but due to many characteristics of oil pipes (long length, many bends, irregular shapes, pipe weight) and other reasons, the product is in the During the welding process, it is necessary to use the crane to lift, move, and assist manual cooperation. On the one hand, the labor intensity of the workers is increased, and on the other hand, the welding efficiency is reduced. After the oil p...
