Problems solved by technology

[0002] Rock sampling is a technical method for inspection or exploration. In the prior art, drill bits are made of many materials, such as manganese steel, carbon steel, tungsten steel, etc. Although the hardness is high, the wear resistance is not enough, resulting in low service life. Constantly replace new drill bits, the cost is high, and the construction efficiency is reduced, there is room for improvement

Embodiment Construction

[0015] The present invention will be further described below:

[0016] The present invention comprises the following steps:

[0017] (1) Add 0.1% carbon, 0.05% manganese, 0.5% cobalt, 0.01% titanium, and iron in the smelting furnace. The manganese uses cobalt iron to adjust the composition to 1:1:3, the cobalt in front of the furnace uses iron to adjust the composition to 1:1, the temperature rises to 1650°C to melt iron into molten iron, and the adjusted carbon is added, the temperature rises to 1680°C, and the adjusted The final manganese, cobalt and titanium are deoxidized and released;

[0018] (2) Add block rare earth alloy with a particle size of 3 to 5 mm at the same time as it comes out of the furnace, mix it and pour it into the ladle;

[0019] (3) Add 0.05% pure aluminum to the ladle, turn over the furnace to tap the steel, and start pouring the casting when the cooling temperature drops to 1550°C, and the volume is 5 times that of the required drill bit;

Abstract

The invention discloses a production method of a rock sampling drill bit. The production method comprises the following steps: performing the casting by adding carbon, manganese, cobalt, titanium andiron, casting, forging, quenching, and then grinding into an available drill bit apparatus. Compared with the prior art, the drill bit produced by virtue of the method disclosed by the invention is high in hardness, high in abrasion resistance, capable of prolonging the service life of a drill bit edge in construction, capable of reducing the probability for replacing the drill bit, decreasing theconstruction cost, and increasing the working efficiency, and wide in application value.

Description

technical field [0001] The invention relates to a workpiece processing method, in particular to a method for manufacturing a rock sampling drill bit. Background technique [0002] Rock sampling is a technical method for inspection or exploration. In the prior art, drill bits are made of many materials, such as manganese steel, carbon steel, tungsten steel, etc. Although the hardness is high, the wear resistance is not enough, resulting in low service life. Constantly replacing new drill bits, the cost is high, and the construction efficiency is reduced, so there is room for improvement. Contents of the invention [0003] The object of the present invention is to provide a method for making a rock sampling drill bit in order to solve the above problems. [0004] The present invention achieves the above object through the following technical solutions: [0005] The present invention comprises the following steps: [0006] (1) Add 0.1% carbon, 0.05% manganese, 0.5% cobalt,...
