    • PROBLEM TO BE SOLVED: To provide a punching apparatus that precisely positions a coil material in a pressing position when performing a punch pressing, to thereby improve yields of materials.SOLUTION: The punching apparatus 10 includes: a feeding device 11 for intermittently feeding the coil material 20 to the pressing position in synchronization with upward and downward movements of a punch 12; a plurality of width position correcting pins 14 for coming into contact with width directional ends of the coil material 20 to correct meandering of the coil material 20 fed by the feeding device 11; and a plurality of feeding position correcting pins 15 for entering a punched blank hole 21 while coming into contact with the outer periphery of the blank hole 21 to correct a feeding position of the coil material 20.
    • 要解决的问题:提供一种在执行冲压时将线圈材料精确地定位在加压位置的冲压装置,从而提高材料的产量。 冲压装置10包括:进给装置11,用于与冲头12的向上和向下运动同步地间歇地将线圈材料20供给到挤压位置; 多个宽度位置校正销14,用于与线圈材料20的宽度方向端接触,以校正由馈送装置11馈送的线圈材料20的曲折; 以及多个进给位置校正销15,用于在与坯孔21的外周接触的同时进入冲孔坯孔21,以校正线圈材料20的进给位置。(C)2012年, JPO&INPIT
