Abstract

PURPOSE:To obtain sufficient buffer function and strength by forming a piston shift hole coaxial with an ammunition bolt at a cushioning material, providing numerous buffer teeth lined up axially on the inner surface of the piston shift hole and providing a piston interlocked with the ammunition bolt at one end part of the piston shift hole. CONSTITUTION:A buffer device 11 is provided with a cylindrical case 12 fixed at the bottom wall 9a of a holding space 9, a cylindrical cushioning material 13 fitted in the cylindrical case 12, a piston 15 disposed at one end of a piston shift hole 14 formed at the center of the cushioning material 13. The cushioning material formed of aluminium, tin, lead, and the like is integrally provided with numerous saw-tooth like buffer teeth 13a lined up axially in the state of being protruded into the piston shift hole 14. When an ammunition bolt 7 is cut off by the explosive force of an explosive, the bolt piece collides against the piston 15, so that the pison 15 moves axially within the piston shift hole 14 of the cushioning material 13. At this time, the piston 15 is displaced moving downward while cutting the buffer teeth 13a in the piston shift hole 14, thus absorbing the moving force of the bolt piece.

(Problem to be Solved by the Invention) However, in the case of the former aluminum/nicum structure, the strength characteristics are relatively excellent and the strength is low, so it is necessary to increase the buffering capacity by 1%. A big stroke is required. Therefore, aluminum honeycomb structures could not be applied to narrow spaces. In order to solve this problem, it is being considered to use lead plates, which have high strength, as an alternative material to the aluminum honeycomb structure. However, in the case of this lead plate, it could not be expected to have a sufficient buffering function against objects colliding with it at high speeds, as it is relatively hard. Therefore, the object of the present invention is to provide a buffer structure for a pyrotechnic coupling/separation device that can obtain sufficient strength and buffer function even when such a lead plate is used. (Means for Solving the Problems) Based on this object, the present invention has two bodies to be connected and fixed to each other with a pyrotechnic bolt that can be cut and separated from the intermediate part, and a 1γI-recorded A holding space for holding a bolt piece formed by cutting and separating the workpiece bolt is formed in the object to be joined, and a buffer member facing the tip of the pyrotechnic bolt is held in the +'+iJ holding space. In the buffer structure of the pyrotechnic coupling and separation device, a piston movement hole coaxial with the bolt is formed in the buffer member, and an inner surface of the piston movement hole is formed! 1) A buffer structure for a pyrotechnic coupling device, in which a plurality of thrust teeth are provided in the axial direction 1r+], and a piston interlocked with the pyrotechnic bolt is disposed at one end of the piston movement hole; It is characterized by the fact that
(Function) According to such a configuration, when the pyrotechnic bolt is cut and separated by the explosive force of the gunpowder and the bolt pieces are displaced at high speed in the axial direction, the piston interlocked with the bolt pieces is moved to the piston of the ui impact material. Moving in the axial direction within the movement hole, the piston moves and displaces while cutting }1 147 (M) in the piston movement hole, absorbing the moving force of the bolt piece.

According to such a configuration, when the pyrotechnic bolt 7 is clearly separated by the explosive force of the fire pear and the bolt nozzle L is displaced at high speed in the axial direction, this bolt piece collides with the piston 15, and this The piston 15 is moved in the axial direction within the piston movement hole 14 of the buffer material. At this time, the piston 15 moves downward in FIG. 2 while cutting the loose fJjm13a in the piston moving hole 14, and absorbs the moving force of the bolt piece. The difference in impact acceleration α between lead plates and aluminum honeycombs will be explained with reference to Figure 4. According to Fig. 4, with the conventional aluminum honeycomb cushioning material, as shown by curve Furthermore, in the case of a conventional lead plate, as shown by curve Y, the impact acceleration α suddenly changes greatly and then rapidly decreases. In contrast, in the present invention, as shown by the line Z, the change value of the curve Z, which changes at an intermediate value between the curves X and Y, depends on the shape and thickness of the buffer tooth 13a. It can be easily changed by changing . [Second Embodiment] FIGS. 5 and 6 show a second embodiment of the present invention. This embodiment shows an example in which a UL impact device 16 is disposed at the bottom of the holding space 9 in place of the loose nail device 11 in the first embodiment. This I! !
