As shown in fig. 1 to 3, a board hammer comprises a board hammer body 1, the board hammer body 1 comprises an installation part 2 and a hammering part 3, the installation part 2 and the hammering part 3 are all along the length direction of the board hammer body 1 extends in the width direction of the board hammer body 1, the hammering part 3 is located on two sides of the installation part 2, a reinforcement body 4 is embedded in the inner side of the hammering part 3, and the reinforcement body 4 is made of a ceramic matrix composite material.
Specifically, the plate hammer body 1 is substantially rectangular, and in the present embodiment, the longitudinal direction of the plate hammer body 1 is defined as the front-rear direction, the width direction of the plate hammer body 1 is defined as the left-right direction, and the thickness direction of the plate hammer body 1 is defined as the up-down direction. The board hammer body 1 comprises an installation part 2 and a hammering part 3, wherein the installation part 2 is used for installing the board hammer, and the hammering part 3 is used for beating materials. The left side and the right side of the installation part 2 are respectively provided with a hammering part 3, and the hammering part 3 at one side can be turned to the hammering part 3 at the other side to continue hammering after being hammered and abraded. The inside of the hammering part 3 is embedded with the reinforcement 4 made of the ceramic matrix composite material, and the reinforcement 4 is more wear-resistant than other parts of the hammering part 3, so that the service life of the whole plate hammer can be prolonged due to the existence of the reinforcement 4 in the use process of the plate hammer.
The manufacturing process of the plate hammer is formed by pouring a high-temperature liquid metal-based material into a plate hammer mold fixed with a ceramic-based reinforcement 4, cooling and solidifying, the solidified product is the plate hammer, the outer side parts of the mounting part 2 and the hammering part 3 are made of the metal-based material, and the reinforcement 4 is embedded in the hammering part 3. The metal-based material can be alloy materials such as high manganese steel, high chromium cast iron and the like. In addition, the reinforcement 4 is further reacted under the impact of the high-temperature metal-based material, and the contact surface of the reinforcement 4 and the hammering part 3 has more dispersed hard phases, so that the interface bonding strength of the reinforcement 4 and the hammering part 3 is higher, the strength of the hammering part 3 is increased, the service life of the hammering part is prolonged, and the reinforcement 4 made of the ceramic-based reinforcement material is more wear-resistant. The ceramic matrix composite material adopted in the scheme is mainly formed by uniformly mixing iron, manganese or alloy thereof with carbides or nitrides of W, Cr, Nb, Mo, Ti or V elements and then sintering, has excellent wear resistance and mechanical strength, and further prolongs the service life of the plate hammer.
