Due to the insufficient wear resistance of the metal on the tool tooth surface, the tooth surface will not be sharp enough after the parts are used for a long time. Use wear-resistant powder on the tool surface for laser cladding and new product processing. It can achieve surface wear resistance, thereby extending the service life of the tool.

Background

The agricultural machinery tool industry mainly uses blades made of metal materials in production. However, due to the harsh working environment of agricultural machinery, hard particles, soil, stones, and other media are often encountered. The core component of the rotary tiller is frequently subjected to damage from quartz during the work process. It is easy to fail due to the wear and impact of plant silicates, weeds, crop straw, etc. According to incomplete statistics, more than 80% of agricultural soil-contacting parts are scrapped due to failure due to abrasive wear. The annual domestic consumption of rotary tillers alone exceeds 250 million. The problem of insufficient tool life of agricultural machinery has become increasingly prominent, which has seriously restricted the transformation and upgrading of domestic agricultural machinery to intelligent agricultural machinery. Laser cladding technology can effectively repair and strengthen these blades, allowing them to have a longer service life in harsh environments, improving agricultural machinery production efficiency and reducing production costs.

The current application of laser cladding technology in the agricultural machinery tool industry

• Blade surface repair
  Agricultural machinery blades often work in harsh environments, and surface wear and damage will inevitably occur. The traditional repair method is to re-sharpen the entire surface of the blade and then re-apply a thin layer, which wastes a lot of material. Laser cladding technology can be used to partially repair the blade surface, saving material usage and manufacturing costs. In addition, the surface of the blade repaired by laser cladding is smoother and harder, further improving the cutting performance.
• Repair of blade wear and damage
  Especially after the agricultural machinery has been used continuously for a period of time, the blades may suffer greater wear and damage due to long-term wear and tear. Traditional methods require replacing all defective blades, which increases cost and time. Laser cladding technology can be used to partially repair defective blades, which can greatly save costs and time. In addition, laser cladding can also strengthen the damaged parts during repair, increasing the overall service life of the blade.
• Improve cutting performance
  Laser cladding technology can also cast suitable alloy casting materials on the surface of the blade to form a surface that is tougher and more wear-resistant than pure steel castings, thus greatly improving the cutting performance of the blade. Blades treated with laser cladding technology can operate more stably in harsh working environments and maintain good cutting effects.
