    • A pyrotechnic cutting device has a guiding housing in which there is arranged a part to be severed, which is fashioned so as to be severable at a cut point by a cutting tool having a cutting chisel. A pressure pulse generator containing a pyrotechnic driving charge is arranged in the cutting device for generating a pressure pulse to drive the cutting tool. In the guiding housing there is arranged, between the pressure pulse generator and the cutting tool, an impact capsule that can be accelerated by the pressure pulse of the triggered pressure pulse generator toward an inner thrust base of the cutting tool on the end of the cutting tool opposite to the cutting chisel. The cutting tool has its cutting chisel abutting the cut point before the impact capsule strikes the thrust base.
    • 烟火切割装置具有引导壳体,其中布置有待切割的部分,其被设计成在具有切割凿子的切割工具的切割点处可切割。 含有烟火驱动电荷的压力脉冲发生器设置在切割装置中,用于产生用于驱动切割工具的压力脉冲。 在引导壳体中,在压力脉冲发生器和切割工具之间布置有冲击胶囊,其可以通过触发的压力脉冲发生器的压力脉冲在切割结束时向切削工具的内部推力基座加速 刀具与切割凿子相对。 切割工具在撞击胶囊撞击推力基座之前,其切割凿子抵靠切割点。
