Description

Technical Field

[0001] The utility model specifically relates to the technical field of welding cooling, in particular to a welding cooling tool for a titanium alloy welded pipe. Background Art

[0002] The choice of weld cooling method depends on many factors. The following are some common cooling methods and their characteristics: Natural cooling: Let the weld cool naturally in the air. This is the simplest cooling method, but the cooling speed is slow and may affect the quality and performance of the weld. Air cooling: Using compressed air to blow and cool the weld can speed up the cooling speed, but the effect may not be as ideal as other methods. Water cooling: Soaking the weld directly in water or pouring water on the weld can significantly speed up the cooling speed, but you need to pay attention to controlling the water temperature to avoid excessive thermal stress. Liquid nitrogen cooling: Using liquid nitrogen to cool the weld can achieve extremely fast cooling speeds, but the cost is high and requires special equipment and operating skills;

[0003] It should be noted that the cooling speed of the weld has an important influence on the welding quality. Therefore, in actual production, it is necessary to select the appropriate cooling method according to the specific situation and strictly control the cooling process to ensure the quality of the weld. At the same time, when performing welding operations, it is also necessary to follow relevant safety regulations and operating procedures to ensure the safety of operators.

[0004] At present, in order to accelerate the cooling efficiency, conventional welding devices usually use water for cooling during welding. In this way, water is directly sprayed on the weld during welding, which causes excessive thermal stress between the pipeline and the weld, resulting in bubbles inside the weld. This cannot effectively guarantee the quality of pipeline welding.

[0005] After searching, Chinese patent publication number CN201820095931.8 discloses a welding cooling adjustment device; comprising a base and a movable rod, the upper surface of the base is hinged with a welding arm, the upper surface of the welding arm is fixedly connected to a cooling bracket, a side surface of the cooling bracket is provided with a first through hole, the inner wall of the first through hole is movably connected to a hose, a middle part of the surface of the movable rod is fixedly connected to a telescopic rod, a side surface of the movable rod is provided with a second through hole, the inner wall of the second through hole is movably connected to the outer wall of the hose, the left end of the hose is fixedly connected to the right end of the rotary joint, the left end of the rotary joint is fixedly connected to a rotary tube, and the other end of the rotary tube is fixedly connected to a cooling head;

[0006] In the process of welding, although the heat can be sprayed to the welded seam through the water nozzle, the water temperature should be controlled to avoid the generation of large thermal stress between the weld and the pipeline that affects the quality of the weld. In addition, when the spray cooling is performed in the above patent, the water contacts the weld to generate a large amount of smoke, and the smoke contains a large amount of harmful substances. The above patent cannot effectively recycle the generated smoke, and the water that is not atomized in the above patent flows around, affecting the surrounding environment.

[0007] In view of the above situation, we provide a welding cooling tool for titanium alloy welded pipes. In this device, the ends of the two pipes to be welded are placed between the rollers on the top of the slide to achieve effective support for the pipes, and the welding ends of the pipes are located between the two spray racks. The cooling water inside the water storage tank is transported to the multiple nozzles on the two spray racks through the pump body and the circulation pipe, so that the multiple nozzles can effectively spray and cool the edge pipes of the pipe welding parts. This can improve the cooling efficiency while not affecting the welds, effectively ensuring the quality of welding. When the water is poured into the basin, the water contacts the welds and atomizes, generating large amounts of smoke, which is effectively collected by the exhaust fan inside the smoke collection hood to achieve centralized treatment of the smoke. The cold zone water that is not atomized is collected by the collection box, and a connecting pipe is provided between the collection box and the water storage tank to achieve a water circulation effect.
