Example Embodiment
[0031] Example 1
[0032] A new type of wear-resistant composite material fan coal mill percussion plate, such as figure 1 , 2 , 3, 4, and 5, including a metal matrix 1, a composite material insert 2, a pin 3, and a rubber ring 4. The metal matrix is evenly provided with through holes and pin holes I. The composite material insert 2 protrudes at one end and the other end It is a stepped shaft. One end of the stepped shaft is covered with a rubber ring 4, the composite material insert 2 is provided with a pin hole II, and the rubber ring 4 is provided with a pin hole III. The composite material insert 2 is embedded on the metal substrate 1, and the pin 3 penetrates Through the pin hole I on the metal base 1, the pin hole II on the composite material insert 2, and the pin hole III on the rubber ring 4, the cross section of the protruding end of the composite material insert 2 is circular. The metal base 1 adopts the model KmTBCr15Mo high chromium cast iron is used as the matrix m...
