Abstract
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
The present invention relates to the processing method of cap in a kind of detonator filling pressing, particularly a kind of method for processing metal inner cap that is beneficial to safe filling of detonator.
Background technology
At present, the processing of the metal inner cap flash hole of detonator, all be by the outside punching press in the inside of metal inner cap, the burr that punching press produces is stretched out by the edge of flash hole, in behind the detonator filling priming during cap pressing, the metallic bur power of interior crown portion under the situation that the floating medicine of priming is being arranged, metal punching pin impact friction when being subjected to pressing, the manufacturability explosion accident easily takes place in the floating medicine of priming under the excitation of interior cap flash hole metallic bur power.
Summary of the invention
Purpose of the present invention is exactly at the deficiencies in the prior art, providing a kind of makes burr that the metal inner cap punching press produces be extended internally by the edge of flash hole, the manufacturability explosion accident that takes place during the cap pressing in preventing behind the detonator filling priming is beneficial to the method for processing metal inner cap of safe filling of detonator.
For achieving the above object, the present invention adopts following technical scheme:
A kind of method for processing metal inner cap that is beneficial to safe filling of detonator, comprise blanking, stretching, towards flash hole, it is characterized in that: towards flash hole the time, drift is by the downward punching press in the top of metal inner cap, and the burr that produces when oppressing towards flash hole is extended to the inside of metal inner cap by the edge of flash hole.
Owing to adopted technique scheme, the burr that produces when making towards flash hole is extended to the inside of metal inner cap by the edge of flash hole, accepts the punching press forward and does not have the increase of burr compression area, can prevent effectively that acupuncture effect from causing priming.
A kind of beneficial effect that is beneficial to the method for processing metal inner cap of safe filling of detonator of the present invention is that cap flash hole in positive bundle the, interior cap metallic bur power are accepted the punching press forward and do not had the increase of burr compression area inwardly, prevent acupuncture effect, cause priming.
Description of drawings
Fig. 1 is the structural representation of metal inner cap of the present invention;
Fig. 2 is the punching course schematic diagram of method for processing metal inner cap of the present invention;
Fig. 3 is blanking, the stretching moulds of industrial equipment figure of metal inner cap of the present invention;
Fig. 4 is that metal inner cap of the present invention is towards flash hole moulds of industrial equipment figure.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing, but therefore do not limit the present invention among the described scope of embodiments.
Referring to Fig. 1, Fig. 2, a kind of method for processing metal inner cap that is beneficial to safe filling of detonator, comprise blanking, stretching, towards flash hole, it is characterized in that: the time towards flash hole 2, drift is by the downward punching press in the top of metal inner cap 1, and the burr 3 that produces when oppressing towards flash hole 2 is extended to the inside of metal inner cap 1 by the edge of flash hole 2.
Referring to Fig. 3, Fig. 4, at first blanking, the stretching moulds of industrial equipment with Fig. 3 metal inner cap 1 stamp out the metal inner cap 1 that does not have flash hole 2; The metal inner cap of using Fig. 4 again to the punching press of the inside of metal inner cap 1, is gone out the flash hole 2 of metal inner cap 1 towards the flash hole moulds of industrial equipment, because the burr 3 that drift by the downward punching press in the top of metal inner cap 1, makes punching press produce extends to the inside of metal inner cap 1.
Described embodiments of the present invention though combine accompanying drawing, those of ordinary skill in the art can make various distortion or modification within the scope of the appended claims.More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
