Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a cooling device for laser cladding. Background Technique

[0002] Laser cladding, also known as laser deposition or laser coating, is an advanced surface modification technology. Laser cladding uses a high-energy density laser beam as a heat source to rapidly melt an alloy with different compositions and properties together with the surface of the substrate, and rapidly solidify within an extremely short time to form an alloy cladding layer with completely different compositions and properties from the substrate. This process involves the rapid melting, mixing, and solidification of the cladding material and the substrate surface, thereby achieving the purpose of surface modification or repair. When laser cladding is performed on a plate, a cooling device is often used to cool down the working area.

[0003] For example, the authorized patent with the publication number CN 215251183 U (an intelligent cooling device for laser cladding): includes a box body, a fixed plate is fixedly connected to the middle position inside the box body, a table board is fixedly connected between the right surface of the fixed plate and the inside of the box body, a groove is opened at the middle position of the upper surface of the table board, a clamping member is arranged inside the groove of the table board, a plurality of lower leakage holes are arranged below the groove of the table board, a collection tray is fixedly connected to the lower surface of the table board and below the groove, and a water outlet pipe is communicated with the center position of the lower surface of the collection tray;

[0004] Although the above-mentioned prior art is convenient to transport the coolant in the liquid tank to the nozzle through the water outlet pipe and the flexible water pipe to cool the workpiece, it does not have the ability of double-sided cooling. Therefore, double-sided cooling cannot be carried out during laser cladding of the plate, which affects the uniformity of plate cooling and is not conducive to the quality of laser cladding of the plate. For this reason, we propose a cooling device for laser cladding. Content of the Utility Model
