Description

Technical Field

[0001] This utility model relates to the technical field of water cooling devices, and in particular to a water cooling circulation cooling device for welded wear-resistant plates. Background Technology

[0002] Wear-resistant steel plates are plate products specifically designed for use in large-area wear conditions. They are plate products made by bonding a certain thickness of wear-resistant layer with high hardness and excellent wear resistance to the surface of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity through a welding method.

[0003] Existing water-cooled circulating cooling devices for welded wear-resistant plates, such as the water-cooled circulating cooling system for welded wear-resistant plates disclosed in utility model patent application number 202120235876.X, mainly include a water tank, a water pump connected at one end to a circulating water pipe, a water pump connected at the other end to an inlet pipe, an outlet pipe connected at one end to the inlet pipe, and a branch cooling pipe connected at the other end. Several spray holes are arranged along the length of the top of the branch cooling pipe, and a welding platform is set above the water tank. In use, the wear-resistant plate is fixed on the welding platform by a clamping device. The water pump draws cooling water from the water tank through the circulating water pipe and sprays it directly onto the bottom surface of the wear-resistant plate through the inlet pipe, outlet pipe, and branch cooling pipe for cooling. The cooling water falls into the water tank due to gravity for collection and recycling.

[0004] However, the water in the existing water-cooled circulating cooling device will gradually heat up during circulation, thus gradually weakening the cooling effect. In addition, the direct contact between the pipe and the wear-resistant plate can easily cause welding slag to fall onto the pipe, affecting its service life. However, if the pipe is far away from the wear-resistant plate, the cooling effect will be reduced. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a water-cooled circulating cooling device for welded wear-resistant plates that can not only dissipate heat from the cooling water and avoid the cooling effect from the temperature rise after multiple circulations, but also avoid the welding slag generated during the welding process from affecting the circulation pipes, thus extending the service life of the device.

[0006] This utility model discloses a water-cooled circulating cooling device for welding wear-resistant plates, including a workbench; it also includes a conveying mechanism, a welding mechanism, a cooling mechanism, and a rinsing mechanism.

The rinsing mechanism is installed on the cooling mechanism and cleans the generated welding slag. The wear-resistant plate is conveyed into the workbench by the conveying mechanism. The welding mechanism is started to weld the wear-resistant plate. During the welding process, the cooling mechanism cools the welding process through water-cooled circulation and dissipates heat from the circulating water to prevent the water temperature from rising and affecting the cooling effect. At the same time, the cooling mechanism delivers water to the rinsing mechanism to clean the welding slag and improve the cooling effect during the welding of the wear-resistant plate.
