Problems solved by technology

[0004] At present, the cutting process of soft metal delay cables in the civil explosive industry is backward. One end of the cut soft metal delay cables has a horseshoe shape and is uneven, which seriously affects the time accuracy and ignition reliability of the delay detonators.
Although there is a device for cutting both ends of the delay cable flattened by the equipment manufacturer, because the two knives are stressed at the same time when cutting the delay cable, the excessive force on the delay cable will cause the delay cable to deform greatly, and also make the surface of the medicine loose. At the same time, there is a waste of raw materials. big disadvantage

Abstract

The invention belongs to the field of civil explosive materials, and discloses a precise cutting device of a soft metal delay cord for an industrial delay detonator, which comprises a guiding fixed cutter, a movable cutter, a dial feeding disc, a trimming cutter and a locating rod, wherein the movable cutter is matched with the guiding fixed cutter; the trimming cutter is matched with the dial feeding disc; at least one feeding hole is arranged on the guiding fixed cutter; the bit of the movable cutter is over the outlet of the feeding hole and contacted with the outer wall of the guiding fixed cutter; a containing groove is arranged on the outer circumferential surface of the dial feeding disc; the notch of the containing groove is opposite to the outlet of the feeding hole and is on the extension line of the outlet of the feeding hole; the locating rod is arranged on the axial extension line of the containing groove; and the locating rod stretches into the containing groove. On the premise of keeping the existing production efficiency, flatness at two ends and precise fixed length of the delay cord are realized; deformation of the delay cord is reduced, therefore, the finished delay cord is precise in length and non-loose in medicinal powder; and the delay time precision and the ignition reliability of an flash detonator are greatly increased.
