Abstract

The invention discloses a metal bayonet for preparing a metal detonating cord. The metal bayonet for preparing the metal detonating cord is characterized in that the metal bayonet is of a tubular structure; the height of the metal bayonet is 50-200mm, the tube external diameter is 100-300mm, and the tube internal diameter is 1-20mm; and upper and lower end openings of the tubular metal bayonet are both provided with branched round tube openings. A cooling method of the metal detonating cord includes the steps that a low-temperature medium refrigerating machine is started at first, and the metal bayonet is pre-cooled; and when the temperature of the metal bayonet reaches -10 to 15 DEG C, a cord making machine is started until cord making is completed. By means of the metal bayonet for preparing the metal detonating cord and the cooling method, potential risks caused by a drying process at the later period of detonating cord making by a water-based single-compound explosive are overcome, and the intrinsic safety level of the detonating cord production process is increased. Compared with the mode of using a high-temperature drying system, the intrinsic safety level of production equipment is increased obviously by using a low-temperature medium; and designability of the metal bayonet of coiled metal foil is fully utilized, and the manufacturing links of the detonating cord are simplified.

Description

technical field [0001] The invention relates to the technical field of detonating cord manufacturing, in particular to a metal bayonet for preparing a metal detonating cord and a cooling method. Background technique [0002] Due to its good flexibility and formability, flexible detonating cord can transmit detonation waves over long distances, and its detonation wave transmission has high directionality, reliability and detonation stability, and has been widely used in weapon and ammunition systems. . [0003] The flexible detonating cord used in large quantities at this stage is mainly silver detonating cord in the military. Since the material of the detonating cord is pure silver, its manufacturing cost and application cost remain high. However, as the detonating cord is more widely used, the material and cost issues have gradually attracted widespread attention from users. Then came the aluminum detonating cord. Aluminum detonating cord is much cheaper to produce than ...
