Wear-resistant bucket tooth is a vulnerable part of the excavator, which can directly execute the working state. The type, strength, weld, plate and other parameters of the grab directly determine its service life. Our company adopts two-dimensional autocad for structural design.3d solidworks conducts stress analysis and working condition simulation. According to the original barrel shape or customer requirements, the material is cut by fully automatic nc flame cutting, and then welded by co2 shielded welding and submerged arc welding.Increase plate thickness, weld Angle and wear-resistant chain plate, zhejiang bucket teeth using automatic sandblasting, spray paint equipment to eliminate welding stress, improve the overall quality of the product, greatly extend the service life of the product.
