摘要： A split die includes a plurality of die pieces which can be assembled into a die nib. The die nib defines a central wire forming passage which has a cross section of a substantially rectangular shape or a square. The cross section of the wire forming passage is progressively smaller such that the wire forming passage has a predetermined approach angle. Each of the die pieces has a passage segment of a generally triangular shape to partially define the wire forming passage. The die piece has a pair of side lines each passing a point on an axial center line of the wire forming passage.
摘要翻译：分割模具包括可以组装成模具笔尖的多个模具片。模具笔尖限定了具有大致矩形形状或正方形的横截面的中心线形成通道。线形成通道的横截面逐渐变小，使得线形成通道具有预定的接近角。每个模具具有大致三角形的通道段，以部分地限定线形成通道。模具具有一对侧线，每条侧线通过线形成通道的轴线中心线上的点。
