Problems solved by technology
When the bucket is working in a mine or a quarry, due to the relatively hard texture of the ore and rock, the friction between the bucket and the material during loading and unloading will cause damage to the loader bucket, especially the main blade and side cutting edge of the bucket. Larger damage, which greatly reduces the reliability and life of the loader bucket

Embodiment Construction
[0009] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0010] A surface treatment method for a loader bucket side wall plate, comprising the following steps: (1) The bucket side wall plate is a high-carbon wear-resistant alloy, and a nickel-based wear-resistant alloy is piled on the surface of the machine bucket side wall plate Welding, so that the outer surface of the cutting edge is formed with a thickness of 5-8 mm. The surfacing process adopts nitrogen gas shielded welding. The welding parameters are welding current of 220-240 amperes, arc voltage of 24-26 volts, and carbon dioxide gas flow of 5 -6 liters / minute; (2) The surface of the side wall plate is treated with sandblasting or shot blasting for the scale treatment.
[0011] In the above method, preferably, th...

Abstract
The invention discloses a surface treatment method of a sidewall plate of a loader bucket, and the method comprises the following steps: (1) the sidewall plate of the bucket is made of high carbon wear-resistant alloy, and the surface of the sidewall plate of the loader bucket is subjected to surfacing of nickel-base wear-resistant alloy, so the surface of a cutting edge forms a thickness of 5 to 8mm, and the surfacing process adopts nitrogen gas shielded welding, and welding parameters are as follows: welding current is 220 to 240 amperes, arc voltage is 24 to 26 volts, and the flow rate of carbon dioxide is 5 to 6 liters per minute; (2) the surface of the sidewall plate is subjected to surface treatment, and the oxide scale is treated by adopting a sand blasting or shot blasting method. The method has the characteristics of fast surfacing speed, firm connection and good product quality.
Description
technical field [0001] The invention belongs to the technical field of loader accessories, and relates to a surface treatment method for a side wall plate of a loader bucket. Background technique [0002] The loader bucket is mainly used for shoveling bulk materials such as ore, soil, coal, and iron slag. The bucket is welded by the main knife plate, side wall plate, arc-shaped bucket wall and support plate. The structure of the bucket is relatively simple, and the structure of the bucket directly restricts the working efficiency of the loader. The service life of the bucket is directly related to the loader. The cost of using the machine. The existing buckets all adopt common steel structure. When the bucket is working in a mine or a quarry, due to the relatively hard texture of the ore and rock, the friction between the bucket and the material during loading and unloading will cause damage to the loader bucket, especially the main blade and side cutting edge of the bucke...
