Abstract

The invention discloses an impact crusher plate hammer and a manufacturing method thereof. The manufacturing method comprises: carrying out the chemical component optimization design, the coasting system process, the molding process, the smelting casting process and the thermal treatment process so as to obtain a quench tempering structure. High comprehensive wear-resisting property can be obtained through the optimization design of chemical components of main elements; the compactness of the plate hammer structure is ensured and the requirements on installation are met through the horizontal manufacturing inclination casting; as wooden molds and high-strength resin sand are adopted for molding, the appearance quality is good; pure molten steel can be obtained by utilizing middle-frequency electro-smelting production and adding composite slagging constituent of limestone and crushed glass; and the high-temperature quenching and high-temperature tempering ensure that the working part of the plate hammer obtains higher hardness and high impact toughness at the same time.

Description

technical field [0001] The invention relates to a blow bar, in particular to an impact crusher blow bar and a manufacturing method thereof. Background technique [0002] The impact crusher has the advantages of simple structure, large crushing ratio and high efficiency, and is widely used in mining, cement, metallurgy, electric power, refractory materials, glass and chemical industries. The blow bar is one of the key and easy-wearing parts of the impact crusher. It is fixed on the rotor of the crusher with wedges. When the crusher is working, the high-speed rotating rotor drives the blow bar to hit the crushed ore with the material at a linear speed of 30~40m / s. The ore feeding particle size is less than 1500mm, the wear is very serious, and the impact force is very large. Therefore, the blow bar is required to have a high Abrasion and impact resistance. In order to ensure the installation requirements of the blow bar, the plane bending deformation of the blow bar shall be...
