DETAILED DESCRIPTION

[0023] Please refer to Figs. 1-3 The utility model provides a kind of welding cooling equipment, including the cooling assembly 2 being installed on welding torch 1 towards pipe material being welded, the cooling assembly 2 is connected with cooling device;

[0024] The cooling assembly 2 comprises a cooling bin 21 connected with the torch body 11 and the nozzle 12 of the welding torch 1 respectively, and the cooling bin 21 is connected with the cooling device;

[0025] The cooling bin 21 is provided with a notch on the side facing the welding direction, and the welding torch 1 is located in the notch. The cooling bin 21 is used for quickly leading out the heat generated on both sides of the moving direction of the welding torch 1 during welding and synchronously cooling the welded seam during welding.

[0026] It should be explained that when the pipe is welded, the welding torch 1 is installed on the output end of the driving mechanical arm, and the pipe is welded by driving the welding torch 1 through the driving mechanical arm. Specifically, the pipe to be welded is positioned by the fixing device, and then the relative displacement between the pipe and the welding torch is caused to weld the spliced end of the pipe. During welding, the pipe can be driven to rotate by the fixing device, and the welding torch 1 remains fixed to weld the annular spliced seam. Alternatively, the welding torch can be driven to move linearly by the driving mechanical arm, and the pipe remains fixed to weld the linear spliced seam of the pipe. During the above welding process, the cooling bin 21 of the cooling assembly 2 quickly leads out the heat diffused on both sides of the moving direction of the welding torch 1 during welding to accelerate cooling. On the other hand, the to-be-welded part is cleaned before welding to improve the welding quality.

[0027] Specifically, the cooling device is a semiconductor refrigeration device, and cold air is transmitted to the cooling bin 21 through a pipeline to cool the welded seam. The driving mechanical arm is a six-axis mechanical arm.

[0028] Further, the cooling bin 21 is provided with a cooling cavity 211 upwardly on the side close to the pipe to be welded. The cooling cavity 211 is arranged along the shape trajectory of the cooling bin 21, and the rear of the cooling cavity 211 is communicated with the cooling device through a temperature insulation hose 28.

[0029] Further, a control pump 29 is arranged between the temperature insulation hose 28 and the cooling device to adjust the pressure and flow rate of the cooling medium, so as to facilitate the rapid cooling of the welded seam of the pipe with different diameters and materials.

[0030] Further, the cooling assembly 2 further comprises a connecting rod 24 and an electric telescopic rod 22. One end of the electric telescopic rod 22 is hinged on the upper end of the side of the cooling bin 21 away from the notch, and the other end is hinged on the lower part of the torch body 11.

[0031] The connecting rod 24 is an L-shaped rod. One end of the connecting rod 24 is provided with a fixing sleeve 26, the fixing sleeve 26 is sleeved and installed in the middle part of the nozzle 12, and the other end side of the connecting rod 24 is rotatably provided with a limiting shaft 25, and the limiting shaft 25 is installed between the two side walls on the inner side of the notch.

[0032] That is, one end of the cooling bin 21 is indirectly connected with the nozzle 12, and the other end is driven by the electric telescopic rod 22 to adjust the distance between the cooling bin 21 and the pipe surface, reduce the gap between the cooling bin 21 and the pipe surface, and improve the utilization rate of the cooling medium and the cooling efficiency.

[0033] Further, the lower end of the cooling bin 21 is provided with an elastic sealing pad 23 along the bin wall.

[0034] Specifically, the elastic sealing pad 23 is made of silica gel or rubber, which is used to improve the adhesion of the lower end of the cooling bin 21 to the pipe, reduce the escape of the cooling medium, and improve the utilization rate of the cooling medium.

[0035] Further, a plurality of cooling holes 27 are provided on the two side surfaces of the slot and located in front of the welding movement direction of the welding gun 1 and on both sides of the weld, and the cooling holes 27 are in communication with the cooling cavity 211. The cooling holes 27 are used to quickly export part of the heat diffused during welding, facilitate rapid cooling, clean the welding part before welding, and improve the welding quality.

[0036] Further, an avoiding opening 30 is provided at the middle of the lower end of the cooling bin 21 and coincides with the welding direction of the welding gun 1, which is used to avoid the weld.

[0037] Further, the cooling bin 21 is in an arc-shaped plate bin or a horizontal plate bin structure.

[0038] It should be explained that the arc-shaped plate bin and the horizontal plate bin structure are respectively used for welding and cooling the annular joint seam and the linear joint seam of the pipe. Specifically, during the cooling of the annular joint seam, the pipe is driven to rotate by the fixing device, the welding gun 1 and the cooling assembly 2 remain stationary, and the cooling assembly 2 rotates with the pipe to cool the weld; during the cooling of the linear joint seam, the welding gun 1 and the cooling assembly 2 are linearly moved by the driving mechanical arm, and the pipe remains stationary to cool the weld.

[0039] During the implementation, the pipe is driven to rotate or the welding gun is moved by the fixing device to weld the joint seam. With the relative displacement of the joint seam and the welding gun, the cooling assembly cools the welded weld synchronously during the welding of the welding gun, improves the cooling efficiency, and through the cooling holes, the welding part is cleaned before welding during the welding of the welding gun, and part of the heat diffused during the welding is exported, which improves the cooling efficiency.

[0040] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
