摘　　要：重锤片是铁路信号继电器磁路系统衔铁组件中的一个零件,在继电器的机械负载和磁路平衡中起着配重的作用,用于保证继电器衔铁可靠落下。通过对比原重锤片的结构尺寸及材料,结合新工艺技术对重锤片的结构尺寸及材料重新研制,主要从重锤片研制的设计输入、理论计算、实物验证等内容,并对重锤片研制前后的实物进行对比分析。新型重锤片的成功研制将提高重锤片零件的防腐性能及应用环境,彻底取消电镀工序对环境质量的影响,同时提高零件的生产效率,缩短产品的生产周期。The heavy hammer,as a part of the armature assembly of the magnetic circuit system of the railway signal relay,plays the role of counterweight in the mechanical load and magnetic circuit balance of the relay to ensure the reliable falling of the relay armature.By analyzing the structural dimensions and material of the existing heavy hammer pieces,and considering the new process technology,this paper proposes the structural dimensions and material of a new heavy hammer piece.It focuses on the design input,theoretical calculation and physical verifi cation of the heavy hammer piece,and carries out comparative analysis on the physical objects before and after the development work.The successful development of the new heavy hammer piece will improve the anti-corrosion performance and application environment of heavy hammer parts,completely eliminate the impacts of the electroplating process on environmental quality,improve the production effi ciency of parts,and shorten the production cycle of products.
