Excavator bucket tooth and preparation process of excavator bucket teeth

Abstract

The invention discloses an excavator bucket tooth which comprises two parts, namely a tooth seat and a plurality of tooth tips, wherein the tooth seat and the plurality of tooth tips are cast independently; the tooth tips are fixed at the front end of the tooth seat side by side; a gap is formed between every two adjacent tooth tips; the roots of the tooth tips are circular; the heads of the tooth tips are in circular arc shapes; the thicknesses of each toot tip is slowly reduced from the root to the head; the bucket tooth is divided into the two parts, namely the tooth seat and the tooth tips which are cast independently, each tooth tip is coated in the tooth seat, the contact area between each tooth tip and the tooth seat is enlarged, the bonding strength of each tooth tip and the tooth seat is greatly improved, and the possibility of falling off of the tooth tips is reduced; due to the creative shapes, the tooth tips can keep sharp all the time; when the excavator bucket tooth is used for excavation, time and labor are saved, and the service life of the bucket tooth is prolonged; components and a preparation process of the bucket tooth are changed, so that the high wearing resistance and shock resistance of the bucket tooth are realized.

Description

technical field [0001] The invention relates to an excavator accessory, which belongs to the technical field of excavators, in particular to an excavator bucket tooth and a preparation process for the bucket tooth. Background technique [0002] On the construction site, the excavator is a kind of machine that is often used. If there is no excavator, it will be very slow to rely on manual construction. The bucket teeth on the excavator are the key parts of the work. The bucket teeth are used in different working environments. The work will be subject to different degrees of wear and impact, and gradually lose its function. Tooth seat It is composed of two parts, the tooth tip and the tooth tip. From the damaged bucket tooth, it can be found that the surface of the bucket tooth in contact with the ground has quite obvious plow-like traces, and the tip has plastic deformation and cracks, because usually the wear of the bucket teeth fails. Some parts often only have tooth tips,...

[0002] On the construction site, the excavator is a kind of machine that is often used. If there is no excavator, it will be very slow to rely on manual construction. The bucket teeth on the excavator are the key parts of the work. The bucket teeth are used in different working environments. The work will be subject to different degrees of wear and impact, and gradually lose its function. Tooth seat It is composed of two parts, the tooth tip and the tooth tip. From the damaged bucket tooth, it can be found that the surface of the bucket tooth in contact with the ground has quite obvious plow-like traces, and the tip has plastic deformation and cracks, because usually the wear of the bucket teeth fails. Parts often only have tooth tips, so the tooth tips must not only have high strength and wear resistance, but also have sufficient plasticity and toughness. However, the current production process and actual conditions cannot meet the work requirements, and the tooth tips are easily damaged.
