Problems solved by technology

However, in the actual processing process, laser cladding has not been widely used in the production of cutting tools. There are two key reasons: First, due to the high laser energy density, it often leads to The deformation of the base material of the tool has a...

Embodiment Construction

[0016] Such as figure 1 As shown, the iron-based alloy Fe62 coating is prepared on the surface of No. 45 steel as the base material of the tool by double-beam laser cladding. The coating has a width of 6 mm and a thickness of 1.48 mm.

[0017] 1. Use a grinding machine to derust the surface of the base material 8 of No. 45 steel, and then wipe the surface with industrial alcohol with a concentration of 99% to remove oil.

[0018] 2. Using a laser beam splitter 2 with a fixed beam splitting ratio of 50%:50%, a beam of laser light emitted by an all-solid-state fiber laser 1 is divided into two beams of L1 and L2. The L2 laser is reflected by the total reflection mirror 3. L1, L2 two laser beams pass through the optical fiber 4, the laser head 5 fixed on the mechanical arm 10, and the focusing lens 7 with a focal length of 200mm, and then act on the tool substrate 8. The laser power is set to 2800W, and the energy at L1 and L2 is distributed. They are 1400W respectively, the ang...

Abstract

The invention discloses a method for processing a double-beam laser cladding tool. Laser is divided into two beams of lasers having equal energy by virtue of a laser beam splitter, the two beams of lasers are respectively focused and simultaneously act on recesses formed in both sides of the substrate of the tool and high-hardness iron-based alloy powder is fed to focal points by virtue of paraxial powder-feeding nozzles for cladding so as to achieve the requirements on set width and thickness. According to the method, the laser processing efficiency can be increased by 20 times compared with that of the conventional tool manufacturing technology, and the method is convenient to operate and high in degree of automation; by the double beams, both sides of the substrate of the tool are simultaneously clad, no need of complex fixtures during cladding is ensured and the substrate of the tool almost has no deformation after cladding.

Description

technical field [0001] The invention relates to a processing method of a double-beam laser cladding tool, belonging to the technical field of laser processing. Background technique [0002] The tool industry is the basic industry of the entire machinery manufacturing industry. Advanced cutting tools are the necessary conditions and guarantee for the production of high-quality, efficient, and low-consumption tools. 1. The processing quality has a great influence, so the selection of tool material and the processing method of the cutting edge are particularly important. [0003] Laser cladding technology is an emerging surface strengthening technology, using this technology to add cladding materials on the surface of the tool base material, and use high-energy-density laser to melt it together with the tool surface, and quickly solidify and crystallize to form a high-hardness coating. layer, thereby improving the performance of the tool itself. However, in the act...
