    • An automatic punching riveting device, comprising a die (18) having a center pin (25) receiving a hollow portion in the leg part (5) of an automatic punching rivet (1) and a die body (27) having a recessed part (26) for guiding the deformation of the leg part tip of the automatic punching rivet in radial outer direction formed on the outer peripheral side of the center pin (25), wherein the center pin (25) and the die body (27) are movably supported, relative to each other, along the axial direction of the center pin (25) facing a punch (14), and a disc spring (41) moves the center pin (25) relative to the die body (27) so that, when the automatic punching rivet (1) pressed by the punch (14) is driven into tightened members (2) and (3) and the leg part tip thereof starts to pierce the tightened member (3) on a receiving side, the center pin (25) can be brought into contact with the die side surface of the tightened member (3) on the receiving side, whereby the restriction of the driving direction of the tightened members can be relieved or eliminated.
    • 一种自动冲孔铆接装置,包括具有中心销(25)的模具(18),所述中心销(25)在自动冲孔铆钉(1)的腿部(5)中容纳中空部分,以及具有凹部 26),其形成在所述中心销(25)的外周侧的径向外方向上引导所述自动冲孔铆钉的腿部末端部的变形,其中,所述中心销(25)和所述模具主体(27) 相对于彼此沿着中心销(25)的轴向方向相对于冲头(14)支撑,并且盘弹簧(41)相对于模具本体(27)移动中心销(25),使得, 当由冲头(14)按压的自动冲压铆钉(1)被驱动到紧固构件(2)和(3)中,并且其腿部末端开始刺穿接收侧的紧固构件(3)时,中心销 (25)可以与接收侧的紧固构件(3)的模具侧表面接触,从而限制了驱动 紧固件的g方向可以减轻或消除。
