An improved plow point and its preparation method

Abstract

The invention relates to an improved plow tip and a manufacturing method of the improved plow tip and belongs to the field of mechanical technology. The improved plow tip comprises a base and a connecting portion installed on the base, one end of the connecting portion is fixedly connected with the base, the other end of the connecting portion is bent outwards and extends to form a working portion, the axis of the connecting portion and the axis of the working portion intersect to form an obtuse angle, a soil division groove is formed in the sidewall, bent towards the working portion, of the connecting portion in an inward concave mode, the soil division groove extends to the tail end of the working portion from the connecting portion, and the distance between the two inner sidewalls of the soil division groove gradually decreases from the joint to the working portion. The improved plow tip is manufactured by alloy steel specifically comprising 0.38%-0.45% of C, 0.8%-1.2% of Mn, 0.17%-0.37% of Si, 0.9%-1.2% of Cr, 0.15%-0.3% of Mo, less than or equal to 0.035% of S and less than or equal to 0.035% of P. The improved plow tip is manufactured by specific materials according to the specific machining method, and is simple in structure, high in tensile strength, good in abrasion resistance and corrosion resistance and long in service life.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to an improved plow point and a preparation method thereof, in particular to an improved plow point for subsoiling and land preparation. Background technique [0002] The plow is a kind of soil tillage machine whose main function is to turn the soil and has the function of loosening and crushing the soil. The plow tip is used to break the soil clods and plow out grooves to prepare for sowing. The forms of plow points mainly include conventional plows, disc plows, and rotary plows. They are usually tied to a group of livestock or motor vehicles that pull it, and are also driven by manpower. [0003] At present, the plow points used by farming machinery are generally welded parts. Welded plow points generally have the problems of low dimensional accuracy, low strength, and difficulty in installation and disassembly. Welding deformation cannot be avoided during welding, which makes the...

AI Technical Summary

Problems solved by technology

[0003] At present, the plow points used by farming machinery are generally welded parts. Welded plow points generally have the problems of low dimensional accuracy, low strength, and difficulty in installation and disassembly. Welding deformation cannot be avoided during welding, which makes the plow share poorly interchangeable; the position of the plow surface Most of them are flaky structures, which have high resistance at the same depth of subsoiling, which is not conducive to the work of plowing; in addition, the material of the plow point is single, its strength is not enough, it is easy to deform, and the wear resistance of the plow point is poor, which greatly shortens the plow time. sharp service life

[0004] To sum up, in order to solve the problems of existing plow points used for subsoiling and land preparation, such as lack of structure, single material, insufficient strength, and easy deformation, it is necessary to design an improved plow point with simple structure, good subsoiling effect and long service life. plow point
