Robot Laser Hardening Machine

Product Overview

This equipment combines a high-power fiber laser with a multi-axis industrial robot, specifically designed for surface laser hardening of metal components. The robot flexibly controls the laser scanning path to achieve precise phase transformation hardening on complex curved surfaces, localized areas, and large workpieces. Widely used in mold manufacturing, automotive industry, construction machinery, rail transit, and metallurgical equipment, it significantly enhances surface hardness, wear resistance, and fatigue life—an advanced heat treatment alternative to traditional induction hardening and flame hardening.

Features

– **Robotic Flexibility**: Equipped with a 6-axis industrial robot, it freely plans 3D scanning trajectories, easily handling complex shapes such as curved surfaces, inner holes, and gear teeth.

– **High-Power Fiber Laser**: Utilizes high-performance fiber laser sources with high energy density, rapid heating, and minimal heat-affected zones for clean and efficient surface hardening.

– **Intelligent Temperature Monitoring**: Integrated infrared pyrometer and closed-loop feedback system monitor real-time temperature, automatically adjusting laser power to ensure uniform hardened depth and hardness.

– **Professional Hardening Software**: Includes offline programming and path planning software supporting 3D model import for quick scan path generation, temperature field simulation, and process optimization.

– **Modular Design**: Laser head options include rectangular, circular, or wobble beams to suit various hardening widths and shapes; can be combined with positioners and guide rails for extra-large workpieces.

Advantages

– **Superior Hardened Layer Quality**: Laser hardening produces refined martensitic structures, increasing hardness by 15%-20% over conventional methods, with enhanced wear resistance and smooth surfaces free from oxidation.

– **Minimal Thermal Distortion**: Concentrated laser energy heats only the surface layer, keeping overall workpiece temperature low and virtually eliminating deformation—ideal for precision parts and thin-walled components.

– **Flexible and Efficient**: Robot programming allows quick changeovers, adapting to diverse, small-batch production; high scanning speeds significantly boost processing efficiency.

– **Eco-Friendly**: No quenching fluids or media required, zero pollutant emissions; energy consumption is only 1/5 to 1/10 of traditional induction hardening.

– **Selective Hardening**: Precisely targets only wear-prone areas, retaining core toughness and extending overall component life.

Applications

– **Mold Industry**: Localized hardening of large stamping dies, die-casting molds, injection molds on surfaces, edges, sliders, and other wear-prone areas.

– **Automotive Industry**: Surface strengthening of crankshafts, camshafts, gears, steering knuckles, brake discs, piston rings, and other high-wear components.

– **Construction Machinery**: Wear treatment of excavator teeth, track pads, hydraulic cylinder rods, mixer blades, and heavy-duty parts.

– **Rail Transit**: Hardening of rails, turnouts, wheel flanges, gearbox bearing seats, and components under severe friction.

– **Metallurgical Equipment**: On-site repair and strengthening of rolls, conveyor rollers, guide plates, and other high-temperature wear parts.

– **General Machinery**: Local hardening of machine tool guides, lead screws, spindles, cutting tools, fixtures, and precision components.
