Description

Technical Field

[0001] The invention relates to the technical field of ship steel structure processing, in particular to a hot riveting welding device for ship steel structure processing. Background Art

[0002] Ship steel structure refers to the steel components that constitute the main skeleton of the ship, which are used to support and bear the weight and load of the hull. Ship steel structure usually needs to have the characteristics of high strength, corrosion resistance, and lightweight to meet the complex working conditions and safety requirements of ships in the marine environment. Steel is often used in ship construction and has good plasticity and machinability. It is easy to weld, cut and shape process, and is suitable for manufacturing structural components of various complex shapes and sizes.

[0003] According to the publication number CN213919641U, a hot riveting welding device for ship steel structure processing is disclosed, which opens a blower to blow air into the chamber, thereby accelerating the air flow speed on the surface of the workpiece and improving the cooling efficiency of the workpiece; opens a refrigeration device to cool the air in the chamber, thereby reducing the temperature of the air flow; and sets thermal insulation cotton to insulate the air flow in the chamber, thereby improving the cooling effect of the workpiece, improving the production quality of the workpiece, and improving practicality. By adjusting the rotating shaft, the jet direction of the nozzle is changed, the convenience of nozzle adjustment is improved, the convenience of workpiece cooling is improved, and the practicality is improved; it also includes a bottom plate, a pillar, a workbench, a base, a cross bar, a rotating shaft, a mounting frame, a nozzle, an air box, a first wind hood, a blower, a refrigeration device and thermal insulation cotton. The top of the bottom plate is connected to the bottom of the pillar, the top of the pillar is connected to the bottom of the workbench, and a rotating device is set at the top of the workbench.

[0004] However, the above device still has shortcomings. A separate nozzle is set to spray and cool the riveted position, but the steel structure of the ship is usually processed with long steel. It is inconvenient for the nozzle to spray and cool the distant position during processing. At the same time, there is a certain distance from the hot riveting welding position, which will lead to a decrease in the cooling efficiency of the cold air. The structure of the above device is also relatively complicated, and the subsequent maintenance cost is high, which is not conducive to promotion and use.

[0005] Therefore, it is necessary to have a hot riveting welding device for ship steel structure processing that has a strong practical design and can allow the refrigerant to enter the winding tube through the through pipe to cool the tube, so that the air is cooled after passing through it, and cooperate with the spiral heat exchanger in the tube to increase the time and contact area of ​​the air in the tube, so that the temperature of the air can be lowered further, which is convenient for the subsequent rapid cooling of the hot riveted rivets.
