Description

Technical Field

[0001] The utility model relates to the technical field of laser processing, in particular to laser cladding equipment with a high-temperature heating function. Background Art

[0002] Laser cladding, also known as laser melting or laser cladding, is a new surface modification technology. It forms a metallurgically bonded additive cladding layer on the surface of the base material by adding cladding material to the surface of the substrate and using a high-energy-density laser beam to melt it together with a thin layer on the surface of the substrate. The cladding layer has low dilution but strong bonding force, and is metallurgically bonded to the substrate. It can significantly improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance or electrical properties of the surface of the substrate material, thereby achieving the purpose of surface modification or repair.

[0003] According to a laser cladding device disclosed in the patent with announcement number CN212025456U, the base includes a fixed plate fixedly connected to both sides of the back side of the top of the base, a cladding mechanism is arranged between the two fixed plates, the cladding mechanism is composed of a threaded rod, a driving motor, a rectangular block, a bracket and a laser head, the laser head is fixedly installed at one end of the bracket, and the other end of the bracket is fixedly connected to the middle part of the top of the rectangular block, dust suction mechanisms are arranged on both sides of the top of the base, the dust suction mechanism is composed of a dust suction box, a filter and a fan, and the dust suction box is fixedly installed on one side of the top of the base.

[0004] By adopting the above scheme, through the coordinated use of the filter, dust box and fan, people can control the fan so that the dust generated during the processing of the workpiece can be sucked into the inside of the dust box and attached to the surface of the filter, so that the dust will not fly around and affect the air environment of the workshop, and the dust of the coating material will be sucked into the dust box for recycling without causing waste of resources. However, in the application process of laser cladding technology, a problem that cannot be ignored is that some materials need to be preheated before cladding. Preheating can reduce the thermal stress of the material, reduce the occurrence of cracks and deformation, and improve the quality of the cladding layer. Since the above scheme does not have the function of preheating the workpiece at high temperature, cracks may be generated during the cladding process due to excessive thermal stress of the material, thereby reducing the overall quality of the cladding layer, and there are certain shortcomings; for this reason, we provide a laser cladding equipment with high-temperature heating function to solve the above problems.
