    • A device for crimping the mouth of a detonator housing comprises a pair of opposed jaws reciprocally movable relative to each other, and a plurality of toothed segments on each jaw. The segments are moveable, are located in a jaw cavity, and together form a segmented ring. The side faces of each segment converge from a broad radially outer end towards a toothed radially inner narrow end. A resiliently stressable biasing element is provided between each adjacent pair of segments. The biasing elements act to space the segments of each pair apart when the jaws are spaced apart from each other, and also act to permit the segments, in response to movement of the moveable segments arising from the closing of the jaws, to abut against one another in series when the jaws are tightly in contact with each another, to form the segmented ring.
    • 用于压接雷管壳体的口部的装置包括可相对于彼此往复运动的一对相对的爪,以及每个钳口上的多个齿形段。 这些段是可移动的,位于颚腔中,并且一起形成分段环。 每个片段的侧面从宽的径向外端朝向齿形的径向内部窄端会聚。 在每个相邻的一对片段之间提供弹性应力偏置元件。 当夹爪彼此间隔开时,偏置元件用于将每对的分隔件间隔开,并且还用于响应于由夹爪闭合而产生的可移动部分的移动而抵靠在一起的部分 当钳口彼此紧密接触时,另一个是串联的,以形成分段环。
