Pipe fitting forming machining method and device for pre-welded bifurcated branch pipes

Abstract

The invention discloses a pipe fitting forming machining method and device for pre-welded bifurcated branch pipes. The pipe fitting forming machining device comprises a pipe bending robot and a clamping rotating device. A tail end bending forming device is used for conducting bending forming on pipe blanks according to a system instruction, the clamping rotating device comprises a clamping device, a first rotating shaft and a second rotating shaft, the clamping device is installed on the second rotating shaft, and the second rotating shaft can drive the clamping device to rotate around the horizontal axis; and the first rotating shaft can drive the second rotating shaft and the clamping device to rotate around the vertical axis together, the clamping device is used for clamping a main pipe of the pipe blanks, and the first rotating shaft and the second rotating shaft are matched with the pipe bending robot to adjust the positions and postures of the pipe blanks and rotate in a linkage mode. The problem of integral bending forming of a component with a plurality of forked branch pipes is solved; and economical benefits are obvious, efficiency is high, and intelligent bending forming is achieved.

Description

technical field [0001] The present invention relates to the technical field of pipe bending processing, in particular to a pipe fitting processing method and forming device based on a digital intelligent robot for pre-welding bifurcated branch pipes. Background technique [0002] At present, the automatic forming equipment for pipe bending processing is usually a CNC pipe bending machine, and the pipe forming process is often the bending of a single pipe, which needs to be connected manually by joints or welding. [0003] The structure of the existing CNC pipe bending machine makes the pipe fittings can only be bent and formed in one time. For the pipe fittings with multiple pre-welded branch pipes, it cannot be formed at one time. It is still necessary to pre-bend each part first, and then manually Connect the branch pipes by welding. If the configuration of the main pipe is too complicated or the branch pipe needs to be welded inside the space configuration, the operation...

[0003] The structure of the existing CNC pipe bending machine makes the pipe fittings can only be bent and formed in one time. For the pipe fittings with multiple pre-welded branch pipes, it cannot be formed at one time. It is still necessary to pre-bend each part first, and then manually Connection of branch pipes by welding

If the configuration of the main pipe is too complicated or the branch pipe needs to be welded inside the space configuration, the operation space required for the movement of the welding torch and the transportation of the welding rod will not be satisfied, resulting in poor weld quality or even complete welding.
