Problems solved by technology

From the 1960s to the present, the number of manufacturers in the domestic bulldozer industry has been stable at about 4. The reason is that the processing requirements of bulldozer products are high and difficult, and mass production requires a large investment. Therefore, ordinary enterprises dare not easily set foot in
[0003] However, bulldozers often encounter many problems when they are working. The most important point is that the blades of bulldozers are easy to wear. Generally, steel can only meet the requirements of hardness, and the matching of strength, toughness, wear resistance and processing performance is not ideal. During use, it is easy to break and cannot be restored after deformation, and the welding performance is not good.
At the same time, there is also the problem that the steps of replacing the shovel blade are extremely complicated, and it is inconvenient for non-professionals to replace them.

Abstract

The invention discloses a shovel blade preparation method and a shovel blade. The shovel blade preparation method comprises the steps: smelting high-purity alloy as a raw material, and processing the raw material into a shovel blade blank material; drilling a mounting hole in the shovel blade blank material in advance, and thus obtaining a shovel blade semi-finished product; forging and rolling the shovel blade semi-finished product, and thus obtaining a shovel blade finished product; finishing the mounting hole of the shovel blade finished product, and thus obtaining the shovel blade, wherein the high-purity alloy contains 0.016-0.019 wt% of vanadium, 0.014-0.017 wt% of chromium, 0.001-0.002 wt% of boron, 0.22-0.25 wt% of carbon, 0.0017-0.0019 wt% of nickel, 1.11-1.13 wt% of manganese, 0.0013-0.0021 wt% of titanium and the balance of iron and inescapable impurities.

Description

Technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a method for preparing a shovel blade and a shovel blade. Background technique [0002] A bulldozer is a machine composed of a tractor as the driving machine and a bulldozer with cutting blades; it is used to clear land, road structures or similar tasks. The production of bulldozers in China only started after the founding of New China. At first, a bulldozing device was installed on agricultural tractors. With the development of the national economy, large-scale mining, water conservancy, power station, and transportation departments have continuously increased the demand for medium and large crawler bulldozers. Although my country's medium and large crawler bulldozers have developed greatly, they can no longer meet the needs of national economic development. need. For this reason, since 1979, my country has successively introduced crawler-type bulldozer production technology...
