Loader shovel tooth and production method thereof

Abstract

The invention discloses a loader shovel tooth comprising an upper tooth part and a lower tooth part; the upper tooth part comprises a tooth top and an upper tooth handle which are integrally molded; the tooth top and the upper tooth handle are arranged in a step shape; the upper tooth handle is located above the tooth top; and the tail end of the tooth top is welded and connected with the top end of a lower tooth handle. The invention also discloses a production method of the loader shovel tooth. Defects in the prior art can be overcome, and the loader shovel tooth is conveniently mounted and used in a use field and is good in wear resistance.

Description

technical field [0001] The invention relates to the technical field of loader accessories, in particular to a loader shovel tooth and a preparation method thereof. Background technique [0002] The tooth tip part of the loader shovel tooth is the working part, and the tooth shank part is used to engage with the loader bucket. The working object of the loader is sand, earth and stone, and the operating environment is harsh. The shovel teeth need to withstand severe material friction and impact. In some high-intensity operations, the shovel teeth can even be replaced once a day. The Chinese invention patent application CN201610063443.4 adopts a split design, which can reduce the cost of use. However, this technical solution has too many modifications to the shape and structure of existing products, and requires higher requirements on process conditions, so that the interference fit between the rear of the tooth and the tip of the tooth can be realized without loosening and fa...

AI Technical Summary

Problems solved by technology

However, this technical solution has too many modifications to the shape and structure of existing products, and requires high requirements on process conditions in order to achieve the interference fit between the rear of the tooth and the tip of the tooth without loosening and falling off.

Secondly, this installation method is very troublesome compared to small non-core components with such frequent replacements. Regardless of disassembly or installation, there are high precision requirements, and the whole vehicle will be driven back and forth due to the wear of one or a certain shovel tooth. It is very inconvenient and unrealistic to go to the designated place to replace it; finally, the wear of the loader in actual use is irregular and irregular. The basic situation is that some shovel teeth are seriously worn in the same operation, and some can continue to be used, and The degree of wear can completely reach the back of the tooth, so if it wears to the back of the tooth, the back of the tooth can no longer realize the function of carrying the tooth tip, resulting in waste; resulting in the proposed structure failing to reflect the process of split processing in this product the superiority of
