Technical Field
[0001] The utility model relates to the field of prefabricated butt welding of composite pipes, in particular to a prefabricated butt welding tool for composite pipes with specifications of 16 inches or less. Background Art
[0002] During the prefabrication butt welding of composite pipes with specifications of 16 inches and below, because the prefabrication length of composite pipes with specifications of 16 inches and below is large, the wall thickness of composite pipes is thin, and there is a lack of water cooling device, it is easy to deform during the prefabrication butt welding process. During the prefabrication butt welding of composite pipes with specifications of 16 inches and below, the assembly of composite pipes is also a common problem: First, the pipe mouths of composite pipes must be matched and aligned without any deviation. Second, during the prefabrication of composite pipes, because composite pipes need to be rotated for welding, composite pipes will deviate during the rotation process, and the welding gun will hit the butt joint of composite pipes during the deviation process. Third, overheating of the composite pipes during the butt welding process will cause the composite pipes to deform, affecting the prefabrication rotation of the composite pipes. Fourth, the prefabricated length of each composite pipe is different, and the position of the fixed composite pipe needs to be changed at any time.
[0003] Therefore, it is necessary to develop prefabricated butt welding tooling suitable for composite pipes of 16 inches and below to overcome the above problems. Utility Model Content

[0013] Beneficial effects: Compared with the prior art, the utility model has the following significant advantages: the slide structure of the utility model has a slide that can move up and down and sideways. The welder with a cross slide will not change the placement of the composite pipe due to the position of the weld during the prefabrication butt welding process.

The welder with a cross slide is equipped with a back protective air pipe, from which argon gas is output for protection during the prefabrication butt welding process. The welder is equipped with a circulating water cooling system. The water in the water tank passes through a sealable water pipe. After the closing devices at both ends of the composite pipe seal the composite pipe, the water pipe enters the composite pipe through the water pipe groove in the head closing device. Water is input when the closing device is opened. Closing the closing device can form water cooling in the composite pipe. After the prefabrication butt welding is completed, the closing device is opened again to re-input water into the water tank.

DETAILED DESCRIPTION
[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0020] The utility model discloses a prefabricated butt welding tool for composite pipes with specifications of 16 inches or less, comprising a slide structure, a circulating water cooling structure, a protective gas structure and an operating platform.
[0021] The carriage structure is provided with an upper and lower carriage 1 and a transverse carriage 3. A welding gun is arranged on the carriage structure, and the position of the welding gun is adjusted by the upper and lower carriage 1 and the transverse carriage 3; the welding gun is connected to the welding wire reel 2. The moving operation of the welding gun, or the position area of the prefabricated butt welding of composite pipes of specifications of 16 inches and below, is more operable. No matter where the butt welding is located or what the specifications of the pipe are, the position of the welding gun can be controlled by moving the upper and lower carriages 1 and the transverse carriage 3, so as to align the weld for welding. In addition, in the process of prefabricated butt welding, errors such as collision of the gun and crooked welding caused by the movement of the composite pipe can be avoided.
[0022] The circulating water cooling structure includes a circulating water tank 4, a closable water pipe 5 and a closing device 6 which are connected in sequence. The closing device 6 is connected to the composite pipe of 16 inches or less. Water is recycled in the circulating water tank 4, and water is input into the composite pipe through the closable water pipe 5. After the prefabrication is completed, the water is output into the circulating water tank 4 again through the closable water pipe 5. When the water in the circulating water tank 4 is input into the composite pipe through the closable water pipe 5, the closable water pipe 5 is inserted into the closing device 6 at the head, and the valve in the closable water pipe 5 will open. After the water delivery is completed, the valve in the closable water pipe 5 will close, so that the water does not flow out. In this way, water cooling can be achieved at the lowest cost during the prefabrication butt welding process.
[0023] The shielding gas structure includes a back shielding gas pipe 7, the end of which is connected to a pipeline merging device 8, and the back shielding gas pipe 7 is located on the side of the welding gun needle 9. The back shielding gas pipe 7 is a device for conveying argon gas. In the welding process, the back shielding gas is indispensable. This tool conveys argon gas to the prefabricated butt welding position through the back shielding gas pipe 7. In addition, the back shielding gas pipe 7 will be fixed together at the position of the welding gun mouth with a pipeline merging device 8 to prevent the back shielding gas pipe 7 from hitting the welding gun needle 9 during the prefabricated butt welding process, and to avoid the phenomenon of gas blockage caused by gas pipe entanglement.
[0024] The operating platform is provided with a slide 12, a head slot 15 and a tail slot 16. The slide 12 is connected to the movable slot 10 through a pulley 11. The movable slot 10 can be moved on the operating platform equipped with the slide 12. Composite pipes of 16 inches and below are placed on the head slot 15, the tail slot 16 and the movable slot 10. The head slot 15, the tail slot 16 and the movable slot 10 are all provided with a retractable support rod 13 for clamping composite pipes of 16 inches and below. The movable slot 10 is provided with a remote control, and the remote control is provided with stop, fix, front and back buttons. An electromechanical box 14 is provided on the side of the operating platform, and the operating platform is provided with a plurality of legs 17. In the process of assembling the composite pipe before prefabricated butt welding, the composite pipe needs to be assembled onto the prefabricated tooling. The movable card slot 10 provides convenience for the assembly process. The movable card slot 10 can move the composite pipe to the specified position, and then fix the composite pipe through the head card slot 15 and the tail card slot 16. The head card slot 15, the tail card slot 16 and the movable card slot 10 are all equipped with retractable struts 13, which can clamp composite pipes of different specifications below 16 inches. The movable card slot 10 is operated by remote control. In the process of prefabrication, because the composite pipe is rotated for butt welding, the composite pipe will be offset, and the welding gun and the weld of the composite pipe are prone to collision. The remote control movable card slot 10 can be used to drive the composite pipe to return to its original position. And the remote control makes the operation more labor-saving and convenient.
