    • An electrode calking apparatus that enables to fix electrodes 2 at positions distant a predetermined distance on a shape memory alloy wire 1 in a condition that the shape memory alloy wire 1 is heated to a temperature recovering an original shape is provided. The electrode calking apparatus 101 comprises: a loading mechanism 20 for applying a predetermined tension to the shape memory alloy wire 1 in an axial direction thereof; a pair of supporting units 4 that supports the shape memory alloy wire 1 at two supporting points distant a predetermined distance in the axial direction, and holds a pair of electrodes each having a portion to be calked; a pair of energization contacting units 5 that contacts the shape memory alloy wire 1 at two contacting points between which a pair of the supporting units 4 are disposed, and supplies electric current between the two contacting points; and a pair of pressing units 6 that fixes the electrodes 2 to the shape memory alloy wire 1 by calking by plastically deforming the portions to be calked of the electrodes 2 held on the supporting units 4.
    • 提供了一种能够在将形状记忆合金丝1加热到回收原始形状的温度的条件下,将电极2固定在形状记忆合金丝1上的规定距离的位置的电极铆接装置。 电极压盖装置101包括:用于在形状记忆合金丝1的轴向施加预定张力的装载机构20; 一对支撑单元4,其在形成记忆合金丝1的两个支撑点处沿轴向延伸预定距离,并且保持一对电极,每个电极具有要被加压的部分; 一对通电接触单元5,其在设置有一对支撑单元4的两个接触点处与形状记忆合金丝1接触,并且在两个接触点之间提供电流; 以及一对按压单元6,其通过使保持在支撑单元4上的电极2的要被压住的部分塑性变形而通过铆接将电极2固定到形状记忆合金丝1。
