specific Embodiment approach 1

[0072] Embodiment 1: An explosive bolt box of this embodiment is composed of a top plate 1, an explosive bolt box back plate 2, and two explosive bolt box slant plates 3; two explosive bolt box back plates 2 are installed on both sides. The bolt box side plate 3; the top of the explosion bolt box back plate 2 and the two explosive bolt box slant plates 3 is provided with a top plate 1; the center of the top plate 1 is provided with an explosion bolt connection hole 4; the explosion bolt box back plate 2 There is a weight-reducing hole 5 in the center;

[0073] The angle α formed by the vertical part of the back plate 2 of the explosive bolt box and the bent part is 160°, and the angle β formed by the bent part and the top plate 1 is 110°;

[0074] Several screw or rivet through holes 6 are provided on the back plate 2 of the explosive bolt box.

specific Embodiment approach 2

[0075] Embodiment 2: This embodiment differs from Embodiment 1 in that: the thickness of the back plate 2 of the explosion bolt box is 13 mm; the thickness of the slant plate 3 of the explosion bolt box is 9 mm; the thickness of the top plate 1 is 30 mm. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0076] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the explosive bolt box is made of carbon fiber or aluminum alloy. Others are the same as in the first embodiment.

Abstract

The invention discloses an explosive bolt box and a preparation method thereof and relates to a bolt box and a preparation method thereof. The explosive bolt box solves the problem that an existing explosive bolt is poor in load bearing capacity, not high in strength, easy to cause pollution by brisance and hard to control. Two explosive bolt box side plates are mounted on two sides of an explosive bolt box back plate; a top plate is arranged on the explosive bolt box back plate and the two explosive bolt box side plates, a weight-reducing hole is formed in the center of the back plate, and a plurality of screws or rivet through holes are formed. The preparation method comprises the following steps of: paving a prepreg on the surface of a valve; putting the valve in a positioning groove; paving residual skin; combining dies; heating; curing; cooling; demoulding; and machining. The explosive bolt box disclosed by the invention is applied to the aerospace field.

Description

technical field [0001] The present invention relates to a bolt box and a method of making the same. Background technique [0002] Explosive bolt is the earliest pyrotechnic device used in spacecraft, and its structure is mainly composed of bolt body and nut. As a connecting piece, the explosive bolt realizes its connection function very similar to the connection method of ordinary bolts or studs, and the two objects can be connected as one by tightening the nut or bolt body. On the outer wall of the medicine chamber of the bolt body, there is a round "V" shaped groove, which forms a weak link in the structure of the bolt body. When the two connecting bodies are about to separate, the main charge burns, and the pressure in the charge chamber rises suddenly. After reaching a certain value, the V-shaped groove part breaks. The capacity is mainly accomplished through the explosive bolts and their corresponding explosive bolt boxes: the secondary structure loads the tensile for...
