摘　　要：针对反击式破碎机中锤头因磨损而失效的特点,研发了一种应用于反击式破碎机的组合型锤头。该锤头以合金钢材料做锤柄,高铬铸铁做耐磨块,采用特殊的异形燕尾槽结构连接锤柄与锤头。锤头连接面结合牢固、抗冲击能力强,而且耐磨块可更换,不仅提高了锤头一次性使用寿命,同时大幅度降低了锤头综合使用成本。Aiming at the failure characteristics of the hammer used in counterattack-type crusher due to wear,a combination-type hammer used in the counterattack-type crusher was developed.The hammer handle is made of alloy steel material,and the wear-resistant blocks is made of high chromium cast iron.the hammer handle and hammer head is connected with a special structure of profiled tapered dovetail.The connecting surface of the hammer is solid,its impact resistances is strong,and the wear-resistant blocks can be replaced,so its serve life improves,its integrated cost significantly reduces.
