[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] This utility model provides a technical solution: such as Figure 1 and Figure 5As shown in this embodiment, a cooling device for heat treatment of dissimilar alloy tube welding includes a processing table 1. The processing table 1 has mounting grooves 11 at both horizontal ends and mounting grooves 12 at both vertical ends. Mounting grooves 11 are located below mounting grooves 12, and their depth is greater than that of the mounting grooves 12.

[0029] like Figure 1-3 As shown, two bidirectional screws 5 are installed in the two mounting slots 11 via bearings. Both ends of the bidirectional screw 5 are threaded to movable blocks 51. Each movable block 51 has a fixed ring 53 fixedly connected to its top side. Electric push rods 54 are arranged circumferentially on the outer side of the fixed rings 53. The output end of the electric push rod 54 passes through the fixed rings 53 and is fitted with a fixed clamp 55, which is located inside the fixed rings 53. V-shaped fixing seats 3 are fixedly connected to the left and right sides of the center of the processing table 1. Each V-shaped fixing seat 3 has a rubber pad 4. A motor 52 is installed at one end of the bidirectional screw 5. The bidirectional screw 6... Motor 2 62 is installed at the end. Motor 1 52 and Motor 2 62 are controlled externally. Guide grooves 13 are opened on both sides of the mounting groove 11 and mounting groove 2 12. Guide blocks 63 are slidably connected to the inner wall of the guide groove 13. The two guide blocks 63 are respectively fixedly connected to the movable plate 61 and the two sides of the movable block 51. The position of the fixing ring 53 can be adjusted according to the length of the dissimilar alloy tube, so that the dissimilar alloy tube can be placed between the fixing ring 53 and the V-shaped fixing seat 3. The surrounding fixing clamps 55 are adjusted according to the size of the dissimilar alloy tube to clamp and fix the dissimilar alloy tube, which is convenient for welding and cooling.

[0030] like Figure 2 and Figure 4 As shown, a bidirectional screw 6 is installed in the mounting groove 12 via a bearing.

By setting two arc-shaped water storage chambers 64 at the weld, the two chambers can match the contour of the weld, ensuring uniform coverage of the weld area with cooling water, rapid and concentrated cooling, shortening cooling time, and improving welding cooling efficiency. Furthermore, the two arc-shaped water storage chambers 64 can be moved closer to or further away from dissimilar alloy pipes via the bidirectional screw 6, making it suitable for welding parts of various diameters and thicknesses. It has strong versatility, and the adjustment can be made to move away after welding, thus not affecting the processing flow.

[0031] This utility model provides a cooling device for the heat treatment of dissimilar alloy tube welding. The specific working principle is as follows: Two dissimilar alloy tubes to be welded are placed between a fixing ring 53 and a V-shaped fixing seat 3. According to the length of the dissimilar alloy tubes, a motor 52 is started to drive a bidirectional screw 5 to rotate, so that the movable block 51 moves on the bidirectional screw 5 until the fixing ring 53 and the V-shaped fixing seat 3 are respectively located at both ends of the dissimilar alloy tubes. Then, according to the diameter of the dissimilar alloy tubes, the surrounding electric push rods 54 are driven so that the fixing clamp 55 clamps and fixes the dissimilar alloy tubes. After welding is completed, a motor 62 is started to bring the arc-shaped water storage chambers 64 at both ends closer to the weld. Water is injected into the arc-shaped water storage chambers 64 through an external cooling water tank and sprayed onto the weld through nozzles 65 to achieve rapid and concentrated cooling.
