Percussion device comprises the shock base 51 be arranged on riveting stake base plate 22, shock base 51 is provided with removedly and hits column sleeve 52, hit column sleeve 52 and be provided with multiple ventilating microhole 53, hit in column sleeve 52 be provided with outer hit post 54 and in hit post 55, hit outward post 54 be arranged in hit directly over post 55 and part is stretched out and hit column sleeve 52, hit post 54 outward and interiorly to hit between post 55 for installing explosive sample 56.The setting of ventilating microhole 53, enabling explosive sample 56 outside 100 shocks that are subject to dropping hammer, hit post 54 makes the outer post 54 that hits hit gas that explosion time under the effect that post 55 moves produces inwardly and discharge and hit outside column sleeve 52, make to hit column sleeve 52, outward hit post 54 and in hit the harm that post 55 produces from explosive sample 56 explosion time, improve hit column sleeve 52, outward hit post 54 and in hit the utilization rate of post 55, reduce experimentation cost.
Hit outward post 54, in hit post 55 and hit between column sleeve 52 and have less gap, thus convenient outer hit post 54, in hit post 55 taking-up with put into, and for explosive sample 56, each test all can produce waste products, being arranged on of gap also reduce to a certain extent explosive sample 56 explosion time externally hit post 54, in hit post 55 and hit the damage that column sleeve 52 causes, and in hit post 55 design be convenient to explosive sample 56 and explode the taking-up of afterproduct, reduce explosive sample 56 product externally hit post 54, in hit post 55 and hit the damage of column sleeve 52.
In the present embodiment, by the opening and closing of pilot relay 62, thus to the power supply of electromagnet 61 whether to control, when relay 62 closes, electromagnet 61 is energized and is with and is magnetic, thus will drop hammer and 100 be adsorbed on electromagnet 61, when relay 63 disconnects, electromagnet 61 power-off demagnetization, lose to drop hammer 100 absorption affinity, namely electromagnet 61 release drops hammer 100, drops hammer and 100 to drop with the form of freely falling body, hit post 54 outside hitting, and then hit explosive sample 56.By arranging longer connection wire, thus pilot relay 62 can be operated outward at safe distance.
The quantity of ventilating microhole 53 can be individual arbitrarily, preferably, the quantity of hitting the ventilating microhole 53 that column sleeve 52 is arranged in the present embodiment is four, by arranging four ventilating microholes 53, the waste gas produced after explosive sample 56 can be made completely to explode discharge outer hit post 54, in hit post 55 and hit between column sleeve 52.
Ventilating microhole 53 to be oriented along the center up and down hitting column sleeve 52 upward or outside along hitting column sleeve 52 radial direction.Can carrying out according to test needs towards arranging of ventilating microhole 53, as long as its opening can be discharged in air smoothly after guarantee explosive sample 56 explodes.
The position of the inner orifice of ventilating microhole 53 can at any part of explosive sample 56 present position, preferably, in the present embodiment, the position of the inner orifice of ventilating microhole 53 is arranged on the middle and upper part of explosive sample 56 present position, the waste gas that such guarantee explosive sample 56 explosion time produces can be got rid of, so avoid to hit outside explosive sample 56 explosion time post 54, in hit post 55 and hit the destruction of column sleeve 52; The position in the outer aperture of ventilating microhole 53 is exposed is clashing into outside base 51 and the surface of contact hitting column sleeve 52, the release of such guarantee explosive sample 56 explosion energy, alleviate externally hit post 54, in hit post 55 and hit the destruction of column sleeve 52.
Because the amount of explosive sample 56 is little, if the aperture of ventilating microhole 53 is excessive, directly can makes energy leakage, affect test effect, contrary, the too little meeting in aperture makes energy leakage not go out, so destroy hit outward post 54, in hit post 55 and hit column sleeve 52.In the utility model, the aperture of ventilating microhole 53 can for being not more than the arbitrary value of the radius of explosive sample 56, and preferably, in the present embodiment, the aperture of ventilating microhole 53 is 0.05 ~ 0.1 times of the diameter of explosive sample 56.
The below hitting column sleeve 52 is provided with the buckle of an annular protrusion, and clash into base 51 and be provided with the annular slot with buckle consistent size, buckle is arranged in this draw-in groove removedly.The buckle that annular is protruded and the design of annular slot, can make to hit column sleeve 52 and clash between base 51 to be well fixed together, when drop hammer 100 fall hit outer hit post 55 time, can reduce hitting column sleeve 52 and the destruction of clashing into base 51.
Drop hammer 100, in the xsect that hits post 55, hit post 54 outward, hit column sleeve 52 and clash into base 51 can be the regular shapes such as square, rhombus, circle, preferably, drop hammer 100 in the present embodiment, in the xsect that hits post 55, hit post 54 outward, hit column sleeve 52 and clash into base 51 be circle, be designed with like this and be beneficial to processing, reduce the use of material, reduce experimentation cost, and the xsect of circle makes it stressed more even, can reduce spoilage.In addition, inside hit post 55, to hit the diameter of post 54 outward consistent.
Inside hitting post 55 and hitting the material that post 54 adopts outward is GRr15, and hitting column sleeve 52 and clashing into the material that base 51 adopts is GRr15 or T10A.Inside hit post 55, hit post 54 and the quenching hardness that hits column sleeve 52 is 60 ~ 65RC outward.
Preferably, drop hammer 100 quality permissible error scope control below 1 ‰.In general, 100 quality of dropping hammer have following scope, and 10kg drops hammer: (10000 ± 10) g; 5kg drops hammer: (5000 ± 5) g; 2kg drops hammer: (2000 ± 2) g.
Riveting stake base plate 22 is arranged on chassis overhang 31 by anti-slip nut 23, enable to drop hammer 100 fall hit outer hit post 54 after whole drop-weight meter ensure to stablize.
The inner side of arbitrary in the two foundation seat steel brackets 21 of left and right is provided with scale 41.0 graduation position of scale 41 must with hit the top of post 54 outward in the same horizontal line, according to the difference of explosive load, scale 41 can move up and down, until 0 graduation position of scale 41 with hit the top of post 54 in the same horizontal line outward, arranging adjustable scale 41 in the present embodiment can the needs of adequacy test well.
In sum, drop-weight meter for testing Shock Sensitivities of Condensed Explosives of the present utility model, dropped hammer by the Control of control system 100 release, can operate at a distance, solve the huge sound that existing drop-weight meter produces when carrying out Shock Sensitivities of Condensed Explosives testing experiment and the harm that harmful gas produces human body, easy to operate and safety.And by arranging some ventilating microholes 53 hitting on column sleeve 52, explosive sample 56 can be made to be got rid of by a small amount of explosion product in instant of detonation and hit column sleeve 52, thus decreasing the damage of hitting parts such as column sleeve 52 grade, reducing experimentation cost.
More than that better enforcement of the present utility model is illustrated, but the invention is not limited to embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
