Abstract

The invention discloses an integrated type high-wear-resistance cutting tooth and a preparation method thereof. The integrated type high-wear-resistance cutting tooth comprises a tooth tip, a tooth body, a tooth shoulder and a tooth handle, wherein each of the tooth tip, the tooth body, the tooth shoulder and the tooth handle is made of a steel-bonded hard alloy / stainless steel alloy or a steel-bonded hard alloy / carbon steel alloy; the steel-bonded hard alloy / stainless steel alloy refers to a composite material of a steel-bonded hard alloy and stainless steel; the steel-bonded hard alloy / carbon steel alloy refers to a composite material of the steel-bonded hard alloy and carbon steel; and from the tooth tip to the tooth handle, the mass percent content of the steel-bonded hard alloy in the steel-bonded hard alloy / stainless steel alloy or the steel-bonded hard alloy / carbon steel alloy is gradually reduced. The working amount of post-period machining is reduced through a powder metallurgy pressurizing method, and the wear resistance of the whole cutting tooth is improved. By applying wear-resisting alloys including the hard alloy and the steel-bonded hard alloy and the like, the stainless steel and the carbon steel, the cost of producing the cutting tooth, mining coal and tunneling is reduced and the wear resistance of the cutting tooth is improved.

Description

technical field [0001] The invention relates to an integrated high wear-resistant pick and a preparation method thereof, belonging to the technical field of powder metallurgy forming and sintering. Background technique [0002] As a wear-resistant part of mining machinery engineering, picks are mainly used in coal shearers and roadheaders. The pick is a kind of coal cutting tool loaded on the drum of the excavator. It bears the main load in the mining process. In the process of mining coal, the complex environment causes the picks of the shearer to wear extremely. In the actual mining process, when the pick cutter body wears to a certain extent, the carbide cutter head is subjected to bending stress and the cutter body falls off. Its manifestations are: pear grooves appear on the cutter body; the carbide tip is ground flat; the carbide tip cracks and falls off at the welding position; the carbide tip is broken. The fragmentation of the cutter head is due to the uneven di...
