Problems solved by technology
[0007] The cemented carbide block used in the first structure has high hardness and good wear resistance, but defects such as incomplete welding, uneven distribution and pores will appear during brazing, and the wear resistance of the gap between the substrate and copper brazing is relatively low. Poor, the hard alloy part is exposed after wear, and it is prone to cracking due to the impact and wear of concrete stones, which will cause the cutting ring to fail quickly
[0008] The second structure is simple and convenient, and the overall performance of the obtained cutting ring is better, but in actual operation, it is difficult to distribute the added reinforcement phase particles evenly, the hardness distribution of the working surface of the cutting ring is uneven, and the surface wear is different during use, resulting in Reduced service life of the cutting ring

The invention discloses a wear-resistant cutting ring, which comprises: a base body and a wear-resistant body arranged outside the base body. The material of the wear-resistant body is a steel-based wear-resistant composite material; The material is machined to form a wear resistant body. The wear-resistant cutting ring of the present invention can effectively improve the strength, hardness and wear resistance of the cutting ring, adopt the centrifugal casting process to refine the structure of the prepared component, improve the strength, hardness and plasticity of the component, and can make microscopic defects reduction, increased density, and the ability to reduce production costs for cutting rings.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a wear-resistant cutting ring. Background technique [0002] The cutting ring is also called the wear-resistant ring (Cutting Ring). It is shaped like a ring and performs shearing motion in the working state. It is an important wearing part on concrete pumping equipment such as tow pumps and pump trucks. Its service life is The length directly affects the performance of related concrete pumping equipment. On concrete machinery such as concrete pumps and pump trucks, the cutting ring is an important part of the concrete pumping system. It is connected with the S-shaped swing pipe and is driven by the swing cylinder to swing from the mouth of the concrete cylinder on one side to the concrete cylinder on the other side. During the movement, the cutting ring and the spectacle plate form a switching friction pair. The cutting ring bears impact force, shear force and fr...
