Embodiment Construction
[0010] 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.
[0011] A method for preparing a main blade of a loader bucket, comprising the following steps: (1) The main blade of the bucket is a high-carbon wear-resistant alloy, and a nickel-based wear-resistant alloy is surfacing welded on the surface of the main blade of the machine bucket to make the blade The outer surface of the mouth is formed with a thickness of 5-8 mm. The surfacing welding process adopts carbon dioxide 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 12-16 liters / Minutes; (2) The surface of the main knife plate is surface treated, and the oxide skin is treated by sandblasting or shot peening. The shot peeni...

Abstract
The invention discloses a preparing method of a main cutter plate of a loader bucket. The method comprises the following steps: (1) the main cutter plate of the bucket is made of high carbon wear-resistant alloy, and the surface of the main cutter 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 carbon dioxide 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 12 to 16 liters per minute; (2) the surface of the man cutter plate is subjected to surface treatment, and the oxide scale is treated by adopting a sand blasting or shot blasting method. The surfacing of the surface of the main cutter plate of the loader is gradually performed in the direction parallel with the cutting edge. 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 preparation method of a main knife 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 bucket relies on the main knife plate to scrape the material into the bucket during the process of scraping the material. The direct contact between the main knife plate and the material produces friction and friction. Collision, its cutting edge wears out quickly. The existing main blades usually have low hardness and fast wear, thereby greatly reducing the service reliability and life of the loader bucket, and need to be replaced frequently, resulting in high cost of use. Contents of the invention [0003] The invention aims at overcoming the defects of the prior art...
