Alloy ripper tooth on a ripper and manufacturing method thereof

Abstract

The invention discloses alloy soil loosening teeth on a soil loosening machine and a manufacturing method thereof. Each alloy soil loosening tooth comprises a tooth tip and a rear base, the front end of each tooth tip is in a trapezoid shape, the thickness of the topmost end part of each tooth tip is smallest, the rear end of each tooth tip is provided with a supporting protection block, the rear end of each tooth top is connected with the corresponding rear base in a casting mode, each tooth tip is made of alloy steel, and each rear base is made of vermicular graphite cast iron. According to the alloy soil loosening teeth on the soil loosening machine, an original inblock cast structure is changed, the use quantity of rare alloy is saved, the production cost is reduced, the soil loosening teeth with high strength, good abrasive resistance and good tenacity are manufactured with the adoption of the scientific manufacturing method and heat treatment, the problem that original soil loosening teeth are not resistant to wear is solved, the service life of the soil loosening teeth is prolonged by 2 times to 2.8 times, and the replacing cost is reduced.

Description

technical field [0001] The invention relates to an alloy ripper tooth on a ripper and a manufacturing method thereof. The high-strength ripper tooth is formed by improving the structure, rationalizing the material composition, brand-new manufacturing method and heat treatment process. Background technique [0002] The material of the ripper teeth on the ripper currently used is generally high manganese steel, which has a single-phase austenite structure at high temperature, has good toughness, and has high wear resistance due to the work hardening of the surface layer under the action of impact load. sex. However, when this kind of steel works in an environment with low impact force, the initial hardness is low and the wear resistance is poor. During use, various deformations often occur on the surface, causing the surface to wear and fall off. Replacement will increase costs, reduce work efficiency, and cause a lot of economic losses. Moreover, most of the ripper teeth on ...

Problems solved by technology

However, when this kind of steel works in an environment with low impact force, the initial hardness is low and the wear resistance is poor. During use, various deformations often occur on the surface, causing the surface to wear and fall off. Replacement will increase costs, reduce work efficiency, and cause a lot of economic losses. Moreover, most of the ripper teeth on the ripper are integrally cast. To make the ripper teeth achieve high strength, wear resistance, and good toughness, a large amount of rare earth must be added. Metal, the production cost is high. In fact, when the scarifier is working, only the front part of the scarifier tooth works. The latter part is not used, worn, and replaced a lot. The frequent replacement of the scarifier tooth causes a lot of waste.
