The rigid fuse head is mainly technically characterized by comprising a fuse 1, a plastic plug 2, a fixing block 3, an igniter wire 4, a fuse head 5 and an insulating sleeve 6; an integral structure is adopted; the fuse 1 is adopted as a body component; the fixing block 3 is added to a part a certain distance away from the front end of the plastic plug 2 to fix the fuse 1; a metal core wire of the fuse 1 at the front end of the fixing block 3 is flattened and bent into two pole pieces, and then the igniter wire 4 is pressure-welded to the bent part of the pole pieces for explosive pressure-welding; igniting powder wraps the igniter wire 4 to form the spherical fuse head 5; and a damp-proof layer is dip-coated on the outer surface of the fuse head 5, and the insulating sleeve 6 is also added to the outer surface of the fuse head 5. The manufacturing process of the rigid fuse head is simplified, manufacturing procedures are reduced, the cost of raw materials is lowered, unqualified products in an electric detonator assembly process are reduced, the uniformity of electrical properties of the electric detonator is ensured, the ignition reliability of the electric detonator is improved, and the product quality of the industrial electric detonator is ensured.
Description
Technical field
The utility model relates to a kind of commercial electric detonator and uses rigid electrical fuze, belongs to the initiating equipment field.
Background technology
Along with the development gradually of commercial electric detonator manufacturing technology and blasting technique, domestic continue to use always in the flexible electrical igniting head of commercial electric detonator assembling highlighted unstable properties, got angry that reliability is not high, structure be prone in impaired, the assembling process yields low, can't realize disadvantage such as reliable accurately explosion.Therefore, various performances all are superior to the development and the exploitation of the rigid electrical fuze of flexible electrical igniting head, become the vital task of commercial electric detonator production industry technology scientific research.
Through effort in recent years; More domestic commercial electric detonator manufacturing enterprises also introduce and have developed several kinds of rigid electrical fuzes; But these rigid electrical fuzes all adopt split type rigid structure; That is: at first sheet metal punching out such as copper, iron are become two pole pieces of rigid structure, the fixed block with the insulating materials manufacturing is fixed then, forms rigid structure; Connect the bridge wire bond or be crimped on the end of two pole pieces subsequently, after the completion again the other end of two pole pieces of rigid structure and payment to a porter is welded or crimping.The rigid electrical fuze manufacture process of this structure is comparatively complicated, operation is more, the cost of raw material is higher.
Therefore, need that a kind of dependable performance of invention, manufacturing process are simple, manufacturing cost economy, rigid electrical fuze that production efficiency is high,, be used for commercial electric detonator production with the place of flexible electrical fuze.
Summary of the invention
The utility model technical problem to be solved has provided that a kind of dependable performance, manufacturing process are simple, manufacturing cost economy, rigid electrical fuze that production efficiency is high, with the place of flexible electrical fuze, is used for commercial electric detonator production.
The technical scheme that its technical problem that solves the utility model adopts is: adopt monolithic construction; Make other split rigid structure no longer separately; But with payment to a porter as main component, connect plastic plug, fixed block, bridge silk, these parts of medicine head and insulating sleeve and become an integral body.Payment to a porter is fixed processing a plastics fixed block, formed rigid structure, be separated with 3-4 millimeter distance between plastic plug and fixed block, after the injection mo(u)lding, payment to a porter is fixed therein apart from plastic plug front end a distance; Simultaneously, the metal core wire of fixed block front end payment to a porter is flattened the back bending, as two pole pieces of rigid structure; And this also can utilize the flow harden characteristic of metal material, to strengthen the external force resistance ability of pole piece, guarantees that the pole span of two pole pieces is consistent; And then the bridge silk is crimped on the bending part of pole piece, and freeze again after the crimping firmly, make between bridge silk and pole piece can keep closely contacting reliably; Coat ignition powder around the bridge silk, form spherical medicine head, and when medicine head outer surface dip-coating damp-proof layer and part increase insulating sleeve and make the medicine head receive accident collision or friction; Play buffering and buffer action, protection medicine head can not sustain damage.Simultaneously, can electrostatic isolation or stray electrical current, improve antistatic property.
The operation principle that its technical problem that solves the utility model adopts is: when plastic plug receives radial pressure, plastic deformation can take place, pressure is delivered in the payment to a porter that is fixed in the plastic plug; Will cause the payment to a porter distortion, make the payment to a porter of plastic plug front end produce outside displacement, when the payment to a porter displacement is delivered to fixed block; Because the fixation of fixed block, and fixed block do not receive the effect of any external force this moment, therefore; Displacement can not pass to the pole piece of fixed block front end; Like this, pole piece just can not produce radial displacement, thereby has guaranteed that the distance between two pole pieces does not change; The bridge silk that is fixed between two pole pieces is not damaged, guaranteed the ignition reliability and consistent electrical property of rigid electrical fuze.
The utility model has been simplified the manufacture process of rigid electrical fuze, significantly reduces manufacturing process, has reduced the cost of raw material, has reached the initial designs target.
Description of drawings
Fig. 1 is the rigid electrical fuze structural representation;
Fig. 2 is a tape insulation sleeve pipe rigid electrical fuze structural representation;
Fig. 3 is the rigid structure sketch map;
Fig. 4 is a rigid electrical fuze detonator assembly structure sketch map;
Among the figure: 1 payment to a porter, 2 plastic plugs, 3 fixed blocks, 4 bridge silks, 5 medicine heads, 6 insulating sleeves.
The specific embodiment
Further describe below in conjunction with 4 pairs of the utility model of accompanying drawing: at first when rigid electrical fuze and detonator assemble, put into the bayonet socket device to detonator earlier, and then rigid electrical fuze 5 vertically in the insertion detonators; Make plastic plug 2 upper surfaces concordant with detonator oral area and bayonet socket device upper surface; Open the bayonet socket device, the bayonet socket device is shunk, on capsule, block twice circle seal; Fix plastic plug 2, guarantee it and can when getting angry, not go out from detonator.
With flexible electrical igniting head assembling detonator the time, the diameter that blocks the twice circle seal that is required very high, generally have only 0.2～0.3 millimeter tolerance; This is because if circle seal diameter is excessive; The phenomenon that the medicine head is gone out from detonator then be prone to take place, if circle seal diameter is too small, then is prone to take place the cracked phenomenon of medicine head 5; Cause substandard product many, production efficiency is not high.And the application rigid electrical fuze then as long as circle seal diameter is not excessive, even the little limit to the bayonet socket device of circle seal diameter is shunk size, can not cause the medicine head to damage yet, and can greatly improve product percent of pass and production efficiency.
