Description
Technical field
The utility model is related to shot-blast unit, more particularly to multistage to accelerate shot-blast unit.
Background technology
Existing shot-blast unit is all the spray gun device used in industry, and the shot-peening of the device is substantial amounts of, random, nothing
Method is used for the mechanistic experimental study of single projectile impact.In order to the mechanism fully simulated industrial shot-peening and study single ball shot-peening is researched and developed
Following this device.
The content of the invention
To solve the deficiencies in the prior art, there is provided a kind of multistage acceleration shot-blast unit, this shot-blast unit is rational in infrastructure,
Shot peening velocity can be effectively improved.
To achieve the above object, the utility model uses following technical scheme：
Multistage acceleration shot-blast unit includes coil accelerator, bullet charging port, is provided with by support in frame and added
Speed pipe, is provided with the first and second accelerating coils and corresponding first striker on accelerating tube, is provided with its front end in accelerating tube
Buffer spring, buffer spring one end is fixedly connected with the front end of accelerating tube, and the other end of buffer spring and the second striker are fixed and connected
Connect, quality of the first striker quality more than the second striker；Accelerating tube front side is fixed with transmitting tube, and transmitting tube is provided with bullet filling
Mouthful, by the second striker impact bullet；Two openings are provided with transmitting tube, in aperture position, are hanged the scraps of paper by paper tablet prop stand
Hang in opening, optoelectronic switch is installed in opening both sides.
Above-mentioned multistage acceleration shot-blast unit, the through hole for allowing the first striker to deviate from is provided with the rear end of accelerating tube.
The utility model, the first striker clashes into the second striker after first, second coil accelerates so that the second striker hits
Speed improves very big when hitting bullet, and the quality of usual second striker is much larger than bullet again, by setting suitable parameter, can make
The velocity of shot of the utility model output is obtained in 40-50 meter per seconds, technical grade shot peening velocity is reached, effectively test specimen can be entered
Row impact, so as to simulate the application of industrial scene.
Simultaneously as be None- identified directly by the speed of the so small bullet of optoelectronic switch test laboratory, and
The utility model amplifies bullet through the action of optoelectronic switch by the scraps of paper so that testing the speed for high speed dust-shot is possibly realized.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram.
Fig. 2 is the utility model sectional view.
Fig. 3 is the utility model electronic circuit connection figure.
Marked in figure：11 first accelerating coils, 12 second accelerating coils, 2 accelerating tubes, 31,32,33 optoelectronic switches, 4 bullets
Ball charging port, 5 are used to suspending in midair the cord of the scraps of paper, 6 transmitting tubes, 71 first strikers, 72 second strikers, 73 buffer springs, 81 frames,
82 supports.
Specific embodiment
Referring to the drawings, multistage acceleration shot-blast unit includes coil accelerator, bullet charging port, and accelerating tube is pacified by support
In frame, the first and second accelerating coils and corresponding first striker, the first and second acceleration lines are provided with accelerating tube
Optoelectronic switch is provided between circle, the rear end perforate of accelerating tube, the first striker can eject the perforate, in its front end in accelerating tube
Buffer spring is provided with, buffer spring one end is fixedly connected with the front end of accelerating tube, the other end of buffer spring and the second striker are solid
Fixed connection, quality of the first striker quality more than the second striker；Accelerating tube front side is fixed with transmitting tube, and transmitting tube is provided with bullet
Charging port, by the second striker impact bullet；Two openings are provided with transmitting tube, in aperture position, by paper tablet prop stand by paper
Piece is suspended in opening, and optoelectronic switch is provided with opening both sides.
In this example, the first striker is placed on the relevant position of the first accelerating coil in accelerating tube, zvs after switch K1 unlatchings
I.e. DC booster can carry out boosting to the dc source of 12V makes voltage reach 380V, and two electric capacity are charged, and charges
After finishing, then closing switch K1 is then turned on switching K2, and now electric capacity can discharge the first accelerating coil, obtain the first striker
Obtain initial velocity necessarily and travel forward, when the first striker moves to optoelectronic switch position, trigger optoelectronic switch, optoelectronic switch
Connection controllable silicon, makes the circuit turn-on of the second accelerating coil, it is achieved thereby that the electric discharge to the second coil, completes and hit to first
Second acceleration of pin.
Accelerated by two-stage, the speed of each striker can reach 10-20m/s substantially.But such speed is not enough,
Therefore in an experiment, we employ the method raising speed that many wheels clash into.The quality of the first striker is more than the second striker, second
The quality of striker is more than bullet, therefore the accelerating coil disposed again, energy is transmitted between three, although kinetic energy was being transmitted
Decay in journey, but speed is improved.
In this example, allow that bullet accelerates to the speed of 40-50m/s by this transmission, in having basically reached industry
The actual speed of shot-peening.
Meanwhile, in order to avoid the second striker is to two impact damages of pipeline junction, between the second striker and pipeline
We employ buffer spring, and the durability of shot-blast unit is so also improved while protective conduit.
After first the second striker of striker impact, can backward eject, through hole is opened up in the rear end of accelerating tube, the first striker can be from
The through hole is dropped out in ground, when launching again, the first striker can be placed at the first accelerating coil by hand.
A small scraps of paper are hung at aperture with fine rule at optoelectronic switch position on transmitting tube, and the scraps of paper block optoelectronic switch
When, switch is in high potential.When the projectile impact scraps of paper are allowed to depart from original position, signal can be left on optoelectronic switch
Fluctuation, so makes immeasurablel Projectile Motion originally, the motion of the scraps of paper is enlarged into, so that the motion of bullet is detected.
Because the scraps of paper are very light, therefore the energy loss that shock is produced can be ignored.Occur by recording two position optoelectronic switches
The time of response, and two distances of position are measured, the speed of bullet can be obtained.
In addition it is also possible to the accelerating coil for being arranged as required to three-level or more stages accelerates to the first striker, with
Phase obtains bigger pellet injection speed.
