Description

[0001] LOW-SHOCK SEPARATION DEVICE [0002]

The present invention relates to a low-impact separating apparatus, and more particularly, to a low-impact separating apparatus that is reliable in order to separate a used structure from an existing apparatus under high altitude environment without adverse effect.

Separation devices are essential components that are used in a variety of weaponry and aerospace industries, such as launch, control, drive, and separation.

Currently, the most widely used separation device is an explosive bolt.

For example, guided weapons are mounted on a launching tube that protects missiles from being exposed to the outside environment, and the missile mounted on the launching tube must be rigidly mounted on the launching tube and must be moved and separated at a desired time during operation . For this purpose, explosive bolts with high structural stability and fast separation response are used.

The detonation bolt is broken by the explosive force of the explosive charged in the bolt body, and the bolt body is cut by the bolt, and the part which is connected by the bolt is separated. When the detonation bolt is separated, it is accompanied by a large vibration and shock such as debris, flame and high shock It has disadvantages.

Therefore, recently, a reliable separation apparatus is required to extend the range of guided weapons and to separate the various structures from the present equipment without adverse effects under high altitude environment.

It is an object of the present invention to provide a method of separating components from each other by using a high pressure generated in the combustion of a powder without using an explosive force generated in explosion of explosives, And a separation device.

According to an aspect of the present invention for achieving the above-mentioned object, the present invention provides a portable terminal comprising: a housing having an upper end and a lower end opened and having a housing space formed therein; A housing cap which is communicated with the upper hole and has a lower hole having a larger cross sectional area than the upper hole, a housing cap coupled to the space between the housing and the cylinder to shield the upper end of the housing, A piston, a pressure cartridge partially inserted into the upper hole of the cylinder to shield the upper end of the upper hole, and a lower portion of the lower hole is inserted through the lower end of the housing to shield the lower hole, A bolt fixed in a state of being inserted into the lower hole, and a valve disposed between the cylinder and the housing stopper, And a metal tube which is compressively deformed when the cylinder moves in the direction of the pressure cartridge due to a high pressure generated during operation, thereby causing shock absorption.

The metal tube adjusts the surface area to adjust the speed of movement of the cylinder operated by the high pressure toward the pressure cartridge.

The metal tube adjusts the material and shape to adjust the degree of impact absorption.

The metal tube is coupled to an outer circumferential surface of the cylinder so as to be disposed between a protruding end formed at a lower portion of the cylinder and the housing stopper so as to restrain the cylinder from moving before operating the pressure cartridge.

The restraint member is a metal body or an elastic body, and a part of the restraint member is supported inside the protruding end of the cylinder in a state where a part of the restraint member is inserted into the insertion hole formed in the bolt, so that the state where the bolt is inserted into the lower hole of the cylinder is fixed And when the cylinder moves in the direction of the pressure cartridge, the bolt is released from the fixed state.

The present invention eliminates the internal locking structure between components by using a high pressure generated in the combustion of a powder without exploiting the explosive force generated in the explosion of a gunpowder, and prevents the metal pipe from colliding with the cylinder and the housing stopper, Impact rescue.

In addition, the present invention prevents the metallic pipe from moving before the high pressure due to the ignition of the powder burned, so that no accidental operation occurs during handling and assembly.

Therefore, it is possible to reduce the amount of the impulse required for operation of the separating device, thereby securing the reliability and facilitating the maintenance and handling of the quality.

FIGS. 2 to 4 illustrate operation of a low-impact separator according to an embodiment of the present invention. FIG.
5 is a photograph showing the state before (a) and after (b) separation of the low-impact separator according to the embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The low-impact separating apparatus of the present invention is designed such that the bolt is separated by releasing the internal locking structure between the components by using the high pressure generated in the ignition of the powder without using the explosive force generated in explosion of the explosive.

1, the low-impact separating apparatus includes a housing 10, a cylinder 20, a housing cap 30, a piston 40, a pressure cartridge 50, a bolt 60, a metal tube 80, .

The housing 10 is formed in a substantially cylindrical shape and has an upper and a lower end opened and a receiving space 11 formed therein. And has an interlocking structure between the components in such a manner that a part of the cylinder 20, the piston 40, the pressure cartridge 50 and the bolt 60 are inserted and coupled to the accommodation space 11. [

A part of the cylinder 20 is inserted into the accommodation space 11 through the upper end of the housing 10. The cylinder 20 has a protruding end 21 having an outer diameter corresponding to the inner diameter of the accommodation space 11 and a cylindrical body 23 having a relatively small outer diameter as compared with the outer diameter of the protruding end 21, .

A clearance space between the housing 10 and the cylinder 20 is shielded by engaging the housing stopper 30 and is provided between the housing stopper 30 and the housing stopper 30 and between the housing stopper 30 and the cylinder 20. [ The airtightness is ensured through the O-rings 29 and 31. [

The housing 10 and the housing stopper 30 can be screwed together by forming a female screw and a corresponding male screw. The screwing of the housing 10 and the housing stopper 30 prevents the housing stopper 30 from being separated from the housing 10 by the pressure when the cylinder 20 moves in the direction of the pressure cartridge 50.

The cylinder 20 has an upper hole 25 opened at the top and a lower hole 27 opened at the lower portion. The upper hole 25 communicates with the lower hole 27, Diameter is larger than that of the hole 25.

The piston (40) is positioned in the lower hole (27) of the cylinder (20). A step 28 is formed at a portion where the upper hole 25 and the lower hole 27 communicate with each other due to a difference in diameter between the lower hole 27 and the upper hole 25, 40 are restricted from moving toward the upper hole 25. The airtightness of the lower hole 27 in the direction of the upper hole 25 is maintained between the inner diameter of the lower hole 27 and the piston 40 through the O-

The piston 40 moves in the direction of the bolt 60 by the high pressure during the operation of the pressure cartridge 50 to help the bolt 60 be easily separated from the housing 10.

The pressure cartridge 50 is partially inserted into the upper hole 25 of the cylinder 20 to shield the upper end of the upper hole 25. [ An airtight seal is maintained between the pressure cartridge 50 and the upper hole 25 of the cylinder 20 by interposing an O-ring 51 therebetween.

The outer diameter of the pressure cartridge 50 and the upper hole 25 of the cylinder 20 are formed with male threads and corresponding female threads so that a part of the pressure cartridge 50 can be inserted into the upper hole 25 in a screw- have. This is because when the high pressure gas is generated in the space between the pressure cartridge 50 and the piston 40, the pressure cartridge 50 is not separated from the cylinder 20 but the space between the pressure cartridge 50 and the piston 40 is expanded So that the cylinder 20 can move in the direction of the pressure cartridge 50.

The pressure cartridge 50 is charged with a gunpowder and operates when power is supplied to generate a gas of high temperature and high pressure. At this time, the generated gas moves the cylinder 20 in the direction of the pressure cartridge 50.

When the power is supplied to the pressure cartridge 50, heat is generated in the heating line, and heat generated by the pressure cartridge 50 may cause the powder to closely contact with the heating line, and the powder may generate the desired pressure by operating the capillary. To create the required pressure here, the desired production pressure can be adjusted by adjusting the amount of the insecticide.

The bolt 60 is partially inserted into the lower hole 27 of the cylinder 20 through the lower end of the housing 10 to shield the lower end of the lower hole 27.

An insertion hole 61 is formed in the bolt 60. A plurality of insertion holes 61 may be formed at regular intervals around the outer circumferential surface of the bolt body 61.

And a restraining member 70 that fixes the state where the bolt 60 is inserted into the lower hole 27 of the cylinder 20 is included. The restraint member 70 is partially supported on the protruding end 21 of the cylinder 20 in a state where a part of the restricting member 70 is inserted into the insertion hole 61 of the bolt 60, Thereby restricting the inserted state in the hole 27. The restricting member 70 releases the state in which the bolt 60 is restrained by pushing the cylinder 20 in the radial direction when the cylinder 20 moves in the direction of the pressure cartridge 50 and separates the bolt 60.

In this embodiment, the portion of the restricting member 70 which is inserted into the insertion hole 61 is spherical and the portion supported by the protruding end 21 may be a rectangular metallic body, an elastic body, or a metal ball.

The housing 10, the cylinder 20, the piston 40, the pressure cartridge 50, and the bolt 60 may be made of stainless steel to ensure durability.

The metal tube 20 is disposed between the cylinder 20 and the housing stopper 30 and is compressed and deformed when the cylinder 20 moves toward the pressure cartridge 50 due to the high pressure generated during operation of the pressure cartridge 50, .

Specifically, the metal tube 80 is coupled to the outer circumferential surface of the cylinder body 23 to be positioned between the projecting end 21 of the cylinder 20 and the housing stopper 30, and before the pressure cartridge 50 is operated, And is compressed and deformed while being pressed by the projecting end 21 which is moved in the direction of the housing stopper 30 when the cylinder 20 is moved toward the pressure cartridge 50 by operating the pressure cartridge 50. [

The compression deformation of the metal end 80 reduces the movement speed of the cylinder 20 in the direction of the pressure cartridge 50 and reduces the amount of impact due to the collision between the cylinder 20 and the housing stopper 30. [

The metal tube 80 may adjust the surface area to adjust the moving speed of the cylinder 20 operating in the direction of the pressure cartridge 50 by the high pressure.

The metal pipe (80) can control the degree of shock absorption by adjusting the material and shape.

The operation of the present invention will be described below.

The operation of the low-impact separator will be described with reference to FIGS. 2 to 4. FIG.

When power is supplied to the pressure cartridge filled with gunpowder, as shown in FIG. 2, the pressure cartridge 50 is operated to burn the gunpowder and generate gas of high temperature and high pressure.

The high temperature and high pressure gas is generated in the direction of the arrow in the upper hole 25 of the cylinder 20. The space between the pressure cartridge 50 and the piston 40 is expanded by the gas generated at this time, And moves in the direction of the cartridge 50.

3, when the cylinder 20 moves in the direction of the pressure cartridge 50, the metal tube 80 restricting the cylinder 20 is moved to the protruding end 21 moving in the direction of the housing stopper 30 So that the speed of movement of the cylinder 20 in the direction of the pressure cartridge 50 is reduced.

Thereby preventing the collision between the cylinder 20 and the housing stopper 30, thereby reducing the impact between the components.

4, when the cylinder 20 moves in the direction of the pressure cartridge 50, an empty space is formed in a portion where the protruding end 21 has moved, and the restricting member 70 is pushed into the empty space The locking structure of the bolt 60 restrained by the restricting member 70 is released.

At the same time, the bolt 60 can be easily separated from the housing 10 while the piston 40 moves in the direction of the bolt 60 by the high pressure generated in the pressure cartridge 50.

Fig. 5 is a photograph showing the state before (a) and after (b) separation of the low-impact separator according to the embodiment of the present invention.

As shown in FIG. 5, it is confirmed that the bolts 60 are cleanly separated without generating debris.

The above-described low-impact separating apparatus has a low-impact structure in which the metal pipe prevents a collision between the cylinder and the housing stopper during operation, thereby alleviating the impact between the components, so that the amount of impact required for operation of the separating apparatus can be reduced.

Particularly, since the above-described low-impact separating device operates the specific parts of the separating device component by using the high pressure generated in the combustion of the powder without using the explosive force generated when explosive explosion occurs, the bolt is separated by releasing the internal locking structure. Shockwave and debris are not generated, reliability is ensured, quality is maintained and handling is easy.

The scope of the present invention is not limited to the embodiments described above, but may be defined by the scope of the claims, and those skilled in the art may make various modifications and alterations within the scope of the claims It is self-evident.
