Specific embodiment
To make the purpose of the present invention, content and advantage clearer, with reference to the accompanying drawings and examples, to the tool of the present invention
Body embodiment is described in further detail.
As shown in Figure 1 to Figure 3, the present embodiment metal jet and ring, which cut flow impact dissipation device, includes damping heap 1, arc
Plate 2, metal cap 3；The damping heap 1, arc panel 2, metal cap 3 are connected in and need in protected object, and the arc panel 2 is surround
It is arranged in damping heap 1 periphery and keeps apart between the two, 3 arranged for interval of metal cap is outer damping heap 1 and arc panel 2
It encloses.The damping heap 1 is column, and side and top surface offer multiple dashpots；3 top of metal cap opens up spray orifice,
Its internal filling soft metal 4.
Specifically, heap 1, arc panel 2, metal cap 3 is damped to consolidate using any one of welding, rivet, being bolted mode
Being connected in needs in protected object.
The dashpot opened up on damping heap 1 includes circumferential recess, top surface annular groove, top surface blind hole and upper angled ditch
Slot；At least one circumferential recess is opened on the cartridge outer surface of damping heap 1, and top surface annular groove is opened in damping heap 1
Cylinder top surface on, top surface blind hole is located at the center of top surface annular groove, upper angled groove have it is multiple, on 1 top of damping heap
It is uniformly distributed, the initiating terminal of each upper angled groove is located at the cylinder top surface of damping heap 1, and clearing end is located at the column of damping heap 1
On external surface.
Wherein, the angle of inclination of each upper angled groove is equal, quantity, width, length, the depth of upper angled groove
The parameters such as degree and diameter, height, hardness, material, layout, shear resistance etc. of heap 1 are damped by level of intensity, the unit impacted
The punching press energy range of area, the frequency of impact, duration, the factors such as oneself state of protected object determine.It is impacting
When intensity is larger, damping heap 1 uses larger diameter and higher hardness, and material has good ductility and higher flow
Energy, upper angled groove number is preferably lacked should not be more, so as to fully containing flow is advisable, impact frequency increases for width and depth,
The height of appropriateness increase damping heap 1；When the inclination angle of upper angled groove is impacted damping heap 1, a part of impact energy turns
The circumferential shear of chemical conversion damping heap 1, suitably increases inclination angle, and improves the strength of materials, can improve the energy caused by circumferential shear
Amount dissipates, this is favourable for mitigating impact, damps the top surface annular groove of heap 1 and blind hole is used to step down for flow, top surface
The size of annular groove and blind hole is determined that flow amount is bigger by the size of flow amount, the depthometer of top surface annular groove and blind hole
Very little bigger, the volume accounting in heap 1 is damped is preferably less than normal, because so can suitably increase damping heap 1 when being impacted
Damping fully absorbs the energy of impact, but damps and be not the bigger the better, the impact upper threshold that can bear with protected object
For reference.
When being subject to impact strength larger, damping heap 1 selects hardness material bigger than normal, such as mild steel；It is being subject to impact strong
When degree is smaller, damping heap 1 selects hardness material less than normal, such as copper, aluminium or its alloy.
Arc panel 2 is made of metal material, and number is set according to the impact strength size being subject to, and is subject to impact strength
When larger, the more setting of number of arc panel 2, when being subject to impact strength smaller, the corresponding number for reducing arc panel 2.
Metal cap 3 is hollow cylinder, is made of Steel material, the soft metal 4 of inside filling for copper, aluminium or its alloy, by
To after impact, the soft metal 4 of 3 the inside package of metal cap becomes metal jet and gushs under the flow compressing of metal cap 3,
A part for impact energy has reformed into the flow energy of metal cap 3 and the kinetic energy of soft metal 4, flow energy, due to metal jet
Direction can arbitrarily set, positive can spray, also can laterally spray, this allows for the momentum vector part change of impact
Direction, so as to reducing the impact to protected object.Metal cap 3 is needed by intensity is higher, the preferable material system of ductility
Make, it is ensured that it is not in fracture phenomena to absorb impact in loading, and soft metal 4 there will be good ductility, higher close
Degree, relatively low hardness, in course of injection, it is to be ensured that secondary injury does not occur.
Serious flow occurs when damping heap 1, the cushioning effect of impact will be used up, at this moment arc panel 2 starts to play and make
With, with after flow damping heap 1, impact is buffered together with metal cap 3；The a little higher than damping heap 1 of 2 material hardness of arc panel,
The flow energy consumption of its unit volume is higher than damping heap 1, it is ensured that impact energy is fully consumed；Damp heap 1, arc panel 2, metal
The material hardness of cover 3 all cannot be excessive, because the conduction of shock wave can be increased by improving hardness, impact energy is made more to act on
Protected object.
It can be seen from above-mentioned technical proposal in the case where being hit, metal cap quickly deforms upon, in metal cap
The soft metal in face is squeezed, and is gushed from the tapping of metal cap as fluid, and an energy part for impact changes into
Thermal energy, kinetic energy and flow energy；After damping is piled up and impacted, while flow occurs, there are annular shearing, in this way, rushing
The energy part hit is converted into thermal energy and flow energy；Due to the damping action of metal cap and damping heap, impact can measure
To very big attenuation, the execution of impact is weakened；The effect of arc panel is the arc when damping heap flow reaches a certain level
The flow damping of plate starts to play a role, and mitigates impact, in this way, can strengthen the effect that damping heap mitigates impact, to impact
Execution further weakens.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
