Abstract

The invention discloses excavator bucket teeth including tooth tips and a tooth holder; the tooth tips are prepared from the following raw materials in parts by weight: 1-2 parts of C, 4-6 parts of Si, 45-65 parts of Mn, 0.01-0.02 part of P, 0.02-0.08 part of S, 40-45 parts of Cr, 10-15 parts of Ni, 10-15 parts of Cu, 0.02-0.05 part of Fe, and 0.12-0.15 part of Al; the tooth holder is prepared from the following raw materials in parts by weight: 3-5 parts of C, 75-85 parts of Si, 65-70 parts of Mn, 0.02-0.05 part of P, 0.05-0.10 part of S, 60-65 parts of Cr, 20-25 parts of Ni, 20-25 parts of Cu, 0.05-0.10 part of Fe, and 0.2-0.5 part of Al. The invention also discloses a production method of the excavator bucket teeth.

Description

technical field [0001] The invention relates to a bucket tooth and a production method thereof, in particular to an excavator bucket tooth and a production method thereof. Background technique [0002] The bucket teeth of the excavator are generally installed at the front end of the excavator bucket, and are in direct contact with materials such as rocks and ores during work. When the bucket teeth cut the material, the bucket teeth and the material move relative to each other, resulting in a large positive extrusion on the surface Force, so that a large friction force is generated between the working surface of the bucket teeth and the material, and the bucket teeth must bear the impact; when digging, they must also bear the action of bending moment. Due to the long-term large impact, the bucket teeth surface produces Different degrees of wear and tear will produce deep furrows, resulting in deformation and shedding. Excavators are now widely used in construction sites and ...
