Specifically, when in use, a worker can manually pick up the nozzle 33 and pull the extension tube 32 to elongate the extension tube 32, so that the distance between the nozzle 33 and the roller frame 2 is increased to adapt to the air-blast cooling of the pipe 300 with a larger size. Then, the roller frame 2 starts to drive the pipe fitting 300 welded with a layer of welding bead to rotate; during the rotation, the nozzle 33 can uniformly blow air to the peripheral wall of the pipe 300; when the pipe 300 rotates for one circle and is cooled to the normal working temperature, the nozzle 33 can stop blowing, the worker loosens the telescopic pipe 32, and the telescopic pipe 32 retracts to the original state to occupy a smaller space and avoid confusion of field management.

The drying pipe 36 is arranged on the workbench 1, one end of the drying pipe 36 is connected and communicated with the air source 31, and the other end is connected with the air inlet end of the extension pipe 32.
Preferably, the drying tube 36 is a transparent hollow tubular structure, and the drying agent is silica gel particles with changeable colors.
The drying tube 36 is arranged on the outer wall of the workbench 1, and is beneficial to timely observation of workers. The silica gel particles can be repeatedly used, the color of the water in the particles can be changed when the water in the particles reaches a certain limit value, and the filtering condition can be intuitively reflected. When the variable colour of granule reaches 2/3 of whole drying tube 36, the staff can replace reserve drying tube 36, and the mode of quick connector is adopted at the both ends of drying tube 36, the convenient change.
In this embodiment, the external dimension of the nozzle 33 gradually increases from the inlet to the outlet, and the nozzle 33 is a flat hollow structure, so as to ensure the blowing to be a fan-shaped air flow, effectively increase the heat dissipation area, and avoid the quality of the weld bead from being damaged due to rapid cooling at a certain point.
Further, the cooling module 3 further comprises a filter 37 and a control valve 38.

The control box 7 is provided with an HMI touch screen 71 (abbreviation for Human Machine Interface) and a control button SB (72) for controlling the air blowing, and the control button SB (72) is electrically connected to the control valve 38. The HMI touch screen 71 and the control valve 38 are electrically connected to the PLC controller 51.
In order to make the working principle of the cooling device between the pipe welding layers more clearly understood by those skilled in the art, the use of the cooling device will be described in detail below.
The actions of clamping, rotating, etc. of the pipe 300 are controlled by the PLC controller 51. The pipe fitting 300 to be clamped is horizontally placed on the roller frame 2, and the instruction requirements of rotation, rotation speed adjustment, welding, nozzle 33 air blowing and the like of the pipe fitting 300 are achieved on the operation box 7 through operation of the HMI touch screen 71. Through clamping device 4 and gyro wheel frame 2, guarantee that pipe fitting 300 can freely steady rotation, reach autogiration welding and autogiration cooling's purpose.
When cooling the welded pipe, the supply air source 31 of the inter-layer cooling device must be kept dry and free of foreign matter such as oil contamination in order to prevent the weld bead from being contaminated by foreign matter such as water vapor and oil contamination. Therefore, the compressed air of the air source 31 needs to pass through the filter 37 (air source triple piece) to perform primary oil-water separation and foreign matter treatment on the air source 31 entering the device, the treated air source 31 is connected to the control valve 38 (electromagnetic valve), and the control valve 38 is controlled by the air control box 6. The dried gas is communicated with the nozzle 33 through the extension tube 32 and the shaping hose 35, and is sprayed out from the nozzle 33. The angle of the nozzle 33 can be adjusted freely by the electromagnet 34 and the shaping hose 35 according to the position of the cooling weld bead, and the device is free from the influence of the position of the weld bead of the pipe 300 and the length of the pipe 300 and flexible to use.
The control circuit of the cooling module 3 has the following two control modes:
the first method is to realize the opening and closing of the electromagnetic valve through the control of a control button SB (72), and to connect the air source 31 to realize the manual cooling air blowing.
The specific operation is as follows: when the interlayer cooling device is manually used, after the welding is completed for one pass, the electromagnet 34 is attracted to the housing 11, and the position of the air blowing nozzle is adjusted by the setting hose 35 so that the nozzle 33 is located at a position about 20CM from the bead cooling position. Selecting the idler wheel frame 2 to idle on the HMI touch screen 71, confirming the rotation speed, and starting clicking; meanwhile, the control button SB (72) is pressed, the air source 31 is connected, the nozzle 33 starts blowing air, the rotation is automatically stopped after the pipe fitting 300 completes one circle of rotation, and the control button SB (72) is closed to stop blowing air.
The second is to realize automatic cooling and blowing through the output control of the PLC 51.
The specific operation is as follows: when the automatic welding is used, the electromagnet 34 and the nozzle 33 are fixed in advance, and a corresponding program is set by the PLC controller 51. Basic information of the pipe 300 (diameter of the pipe 300, wall thickness) and welding parameters (current, voltage, welding speed, cooling speed, etc.) are input at the welding device. After the completion of the confirmation, the start button is pressed, and the welding apparatus automatically starts welding while the roller frame 2 is rotated synchronously. After a welding pass is finished, the nozzle 33 is automatically started to start blowing and cooling, and then automatic welding is carried out after cooling is stopped, and the equipment reciprocates until the whole pipe fitting 300 finishes working.
To sum up, above-mentioned pipeline welding layer cooling arrangement's advantage lies in:
firstly, the interlayer cooling device is simple and small, does not occupy larger space, has good flexibility, and can meet the cooling requirements of various pipe fittings 300 in length and various welding seam positions. And the pipe fitting 300 can rotate automatically by matching with the roller carrier 2, and can be cooled by automatic air blowing. Meanwhile, manual and automatic gas flow and pipe fitting 300 rotation cooling speed adjustment are met, and the welding process of automatic welding and idle interlayer cooling is achieved. Therefore, the cooling time of the interlayer temperature is greatly shortened, the idle work of personnel is reduced, and the use amount of the stainless steel welding back argon protective gas is reduced. The stable cooling time of the single welding is shortened to 20 percent of the original stable cooling time, the welding efficiency is improved, and the manufacturing period is shortened. For the non-ferrous metal pipe fitting 300, the cooling time is reduced, the argon filling using time is reduced, and the using amount of argon is reduced.
Then, the drying tube 36 adopts reusable allochroic silica gel particles, which can be recycled, thus saving cost.
Finally, the external dimension of the nozzle 33 is gradually enlarged from the inlet to the outlet, and the nozzle 33 is of a flat hollow structure, so that the blowing is ensured to be fan-shaped air flow, the heat dissipation area is effectively increased, and the quality of the welding bead is prevented from being damaged due to rapid cooling at a certain point.
