Abstract
The utility model relates to a shooting device with a Hopkinson pressure bar and particularly relates to a bullet shooting device with the Hopkinson pressure bar. The bullet shooting device comprises a supporting platform (11), a shooting cavity (12), a shooting tube (13) and a base (15), wherein the shooting cavity (12) is fixed on the supporting platform; the shooting tube (13) is connected with the shooting cavity; the base (15) bears the supporting platform; the supporting platform (11) is provided with a sliding bracket (14) for supporting the shooting tube (13) along the length direction; one end of the shooting tube (13), which is close to the shooting cavity (12), is provided with a bullet loading port (131) which is provided with a sealing door (132). Compared with the traditional device, the bullet shooting device has the advantages that bullets can be loaded into the tail end of the shooting tube from the bullet shooting port instead of being filled from an opening of the shooting tube, and then an iron wire is jacked into the shooting tube, so that great convenience is brought for loading of the bullets, and the use efficiency is improved.
Description
Technical field
The utility model relates to a kind of emitter of Hopkinson pressure bar, specifically a kind of bullet emitter of Hopkinson pressure bar.
Background technology
Most of materials are at the LOADING RATES or the strain rate sensitivity that all show aspect the mechanical properties such as intensity to a certain degree, the strain rate effect of the short duration pulse of high amplitude and the caused mechaanical property of materials of load, structural design and analysis for anti-dynamic load are very important, these dynamic loads are from conventional weapon penetration and blast, many military and civilian events such as occasional burst and high-speed impact, Hopkinson bar is acknowledged as the most frequently used experimental facilities of the most effectively studying the mechaanical property of materials under pulse Under Dynamic Load, it is not only applicable to compression test, can also successfully stretch, shear and friction-wear test, and can expand to and there is acceleration, power and pressure sensor calibrating function.When using Hopkinson pressure bar to test, need to be in its power valve loading, then utilize gases at high pressure and by its pressure abrupt release, bullet is got out, impact experiment apparatus, traditional Hopkinson pressure bar is all to insert from the mouth of pipe of power valve when loading, because power valve is long, so need bullet be headed into power valve end with iron wire, the very trouble that operates, and lose time.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of bullet emitter of Hopkinson pressure bar that can rapid reloading bullet.
The utility model is to solve the problems of the technologies described above adopted technical scheme to be: a kind of bullet emitter of Hopkinson pressure bar, comprise brace table, be fixed on the base of the emission cavity on brace table, the power valve being connected with emission cavity and bearing support platform, on brace table, be provided with along its length for supporting the sliding support of power valve, at power valve, near one end of emission cavity, be provided with port, port place is provided with hermatic door.
The utility model is provided with port at power valve near one end of emission cavity, and port place is provided with hermatic door, when using Hopkinson pressure bar to fill bullet, can directly open hermatic door, and bullet is inserted in power valve, carries out next step operation.
As further setting, the side of port is provided with cotter way, the side of hermatic door is provided with and the corresponding slideway of cotter way, hold-open catch is housed in slideway, make hermatic door when closed condition, can promote hold-open catch along slideway it is entered in cotter way, the pin of increase plugs together fixing structure and can be good at hermatic door to be fixed on power valve, avoid excessive in use impact air-flow that hermatic door is backed down, cause security incident; On emission cavity, be connected with nitrogen tube, during use, be used for passing into high pressure nitrogen in emission cavity, as the power source in emission cavity.
As further setting, on brace table, along brace table bearing of trend, be provided with chute, the bottom of sliding support is provided with and chute projection accordingly, and sliding support can be slided along chute, can select easily the fixed position of sliding support since like this.
As further setting, on described brace table, offer shock relieve vent, slow down the impact concussion of Hopkinson pressure bar when emission bullet.
Beneficial effect: the bullet emitter of a kind of Hopkinson pressure bar of the utility model is provided with port at power valve near one end of emission cavity, port place is provided with hermatic door, compare with traditional device, the utility model can make bullet pack power valve end into from port, need not from the mouth of pipe of power valve, insert bullet again, then with iron wire, head into power valve, the filling that this just greatly facilitates bullet, has improved service efficiency.
