Embodiment Construction
[0012] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the described embodiments.
[0013] see figure 1 , figure 2 , a metal inner cap processing method that is beneficial to the safety of detonator filling, including blanking, stretching, and punching the fire hole, is characterized in that: when punching the fire hole 2, the punch is punched downward from the top of the metal inner cap 1 , The burrs 3 produced when pressing the fire transmission hole 2 extend from the edge of the fire transmission hole 2 to the inside of the metal inner cap 1 .
[0014] see image 3 , Figure 4 , first use image 3 The metal inner cap 1 without the fire transmission hole 2 is stamped out by the blanking and stretching tooling die of the metal inner cap 1; Figure 4 The metal inner cap punching fire hole tooling die punches the inside of the metal inner cap 1, and punches out th...

The invention discloses a method for processing a metal inner cap facilitating the safe filling of a detonator, which comprises blanking, stretching, and punching of a flash hole. The method is characterized by that a punch is punched downwards by the top of a metal inner cap during the punching of a flash hole, and that burrs generated during the punching of the flash hole are forced to extend from the edge of the flash hole to the interior of the metal inner cap. The inventive method for processing a metal inner cap facilitating the safe filling of a detonator has the advantages that the flash hole is punched from the exterior of the inner cap to the interior thereof such that metal burrs of the inner cap face inwards, and that the compression area of a location without burrs where punching is performed is increased, thereby preventing an acupuncture effect from initiating a primary explosive.
Description
technical field [0001] The invention relates to a processing method for filling and pressing an inner cap of a detonator, in particular to a processing method for a metal inner cap which is beneficial to the safety of detonator filling. Background technique [0002] At present, the processing of the fire transmission hole of the metal inner cap of the detonator is stamped outward from the inside of the metal inner cap, and the burrs generated by stamping extend outward from the edge of the fire transmission hole. , the metal burr on the top of the inner cap is impacted and rubbed by the metal punch during pressing when there is a priming charge floating charge, and the priming charge floating charge is excited by the metal burr in the fire transmission hole of the inner cap, and a technological explosion accident is likely to occur . Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art, to provide a method...
