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

A kind of surface treatment method of loading shovel sidewall paneling
Technical field
The invention belongs to loading machine accessory technical field, relate to the surface treatment method of loading shovel sidewall paneling.
Background technology
Loading shovel is mainly used in the bulk materials such as shovel dress ore, earth, coal, iron quarrel.Scraper bowl is welded by plate of operating, sidewall paneling, arc headwall and gripper shoe, and bucket configuration is more single, and the structure of scraper bowl directly governs the operating efficiency of loading machine, and the service life of scraper bowl is directly connected to the use cost of loading machine.Existing scraper bowl all adopts common iron structure.When scraper bowl is in the places such as mining site or building stones field during operation, because the quality of ore, rock is harder, during handling, the friction of scraper bowl and material is to loading shovel, especially the operator plate of scraper bowl and side cutting edge cause comparatively havoc, thus greatly reduce dependability and the life-span of loading shovel.
Summary of the invention
The present invention is intended to the defect overcoming prior art, provides a kind of surface treatment method of loading shovel sidewall paneling, has built-up welding speed fast, is connected firmly, the feature of good product quality.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of surface treatment method of loading shovel sidewall paneling, comprise the steps, (1) bucket sidewalls plate is high-carbon antifriction alloy, nickel-base antiwear alloy welding deposit is carried out on the surface of device mechanical shovel bucket sidewall paneling, making the outer surface of cutting edge form thickness is 5-8 millimeter, and its bead-welding technology adopts nitrogen protection weldering, and welding parameter is welding current is 220-240 ampere, arc voltage is 24-26 volt, and carbon dioxide gas flow is 5-6 liter/min; (2) surface treatment is carried out on sidewall paneling surface, adopts blasting method or ball blasting method to oxide skin process.
Further, ball blasting method carries out shot-peening for using net belt type shot-blasting machine to oxidation sheet.
Compared with prior art, the present invention has following beneficial effect:
The present invention has easy to make, and adopt carbon dioxide gas arc welding, built-up welding speed fast cladding rate is high.It is undertaken by road according to the direction being parallel to cutting edge that built-up welding is carried out on the surface of loading shovel sidewall paneling, makes being connected firmly of metallic welded surfacing layer and sidewall paneling, difficult drop-off.
Detailed description of the invention
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
A kind of surface treatment method of loading shovel sidewall paneling, comprise the steps, (1) bucket sidewalls plate is high-carbon antifriction alloy, nickel-base antiwear alloy welding deposit is carried out on the surface of device mechanical shovel bucket sidewall paneling, making the outer surface of cutting edge form thickness is 5-8 millimeter, and its bead-welding technology adopts nitrogen protection weldering, and welding parameter is welding current is 220-240 ampere, arc voltage is 24-26 volt, and carbon dioxide gas flow is 5-6 liter/min; (2) surface treatment is carried out on sidewall paneling surface, adopts blasting method or ball blasting method to oxide skin process.
In said method preferably, ball blasting method carries out shot-peening for using net belt type shot-blasting machine to oxidation sheet.
Last it is noted that the foregoing is only explanation embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
