Description
Technical field
The utility model belongs to piston field, is specifically related to a kind of bunker wall vibration pneumatic hammer piston.
Background technology
Pneumatic hammer is as a kind of conventional dredging device, more common in industry spot.
Pneumatic hammer is in the process of work, and inner piston has played crucial effect, and the crank motion of piston, has realized the rapping of pneumatic hammer.
But piston is in the process of motion, bearing huge impulsive force, requirement of strength to piston is higher, wants to obtain reasonable ramping effect simultaneously, and the leak tightness of piston also plays an important role, on the other hand, the environment that pneumatic hammer uses is more severe, has unavoidably impurity and enters its inside, and piston is caused to wearing and tearing, thereby reduction ramping effect, affects the whole service life of pneumatic hammer.
Utility model content
The utility model aims to provide a kind of simple in structure, the bunker wall vibration pneumatic hammer piston that result of use is good.
For solving the problems of the technologies described above, the utility model discloses a kind of bunker wall vibration pneumatic hammer piston, comprise piston head and piston rod, described piston head is provided with leading section and rearward end, the leading section of described piston head is provided with magnet groove, in described magnet groove, is provided with magnet, and rearward end is fixedly connected with one end of piston rod, the other end of piston rod is provided with spring groove, is provided with spring in spring groove.
Further, the sidewall of described piston head is provided with several seal grooves, and in seal groove, correspondence is provided with seal ring.
Described seal groove has three.
Further, the material of the prime seal ring of described close piston head leading section is asbestos, is guide ring near the final-stage seal circle of piston head rearward end.
Further, described magnet groove is circular, is positioned at the center of the leading section of piston head, the more than 2/3rds of the end face diameter that the diameter of magnet groove is piston head.
Further, both sides, described spring groove end correspondence is provided with block, and the distance between two blocks is less than the width of spring groove, and described block is fixedly connected with spring groove.
Further, the material of described piston head and piston rod is alloy steel.
The disclosed bunker wall vibration pneumatic hammer of the utility model has following beneficial effect with piston: 1, piston head leading section arranges magnet, and piston can be resetted in time; 2, on the sidewall of piston head, several seal rings are set, in several seal rings, have and can play lubricating effect, also have and can play directional tagging, avoided the dry friction of piston, extended the service life of piston; 3, piston rod end arranges spring groove, spring groove is fixed with spring, in both sides, spring groove end, block is set simultaneously, and the distance between two blocks is less than the width of spring groove, thereby the thing of avoiding to greatest extent spring to depart from piston rod occurs, and has ensured on-the-spot employee's safety; 4, piston head and piston rod adopt the material of alloy steel, have ensured the intensity of piston.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
The utility model discloses a kind of bunker wall vibration pneumatic hammer piston, in the process using, need to strengthen the problem of piston reset, sealing, lubricated and intensity, by magnet being set in piston nose portion, ensure the timely reset of piston, it is the prime seal ring of asbestos that material is set, ensure lubricating in piston movement process, the final-stage seal circle arranging is guide ring, play further sealing function, play the effect of guiding simultaneously, aspect piston material, set about, strengthen the material of piston simultaneously.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical solution of the utility model is clearly and completely described, described embodiment is only a part of embodiment of the present utility model.
The utility model embodiment provides a kind of bunker wall vibration pneumatic hammer piston, as shown in Figure 1, comprise piston head 1 and piston rod 3, the material of piston head 1 and piston rod 3 is alloy steel, thereby ensure the intensity of piston, piston head 1 is provided with leading section and rearward end, the leading section of piston head 1 is provided with magnet groove 2, described magnet groove 2 is circular, its diameter is 2/3rds of piston head 1 end face diameter, thereby ensure being evenly distributed and enough adsorption affinitys of magnetic force, in magnet groove 2, be provided with magnet, the metallic material of magnet and pneumatic hammer inside is used in conjunction with, ensure the timely reset of piston.On the sidewall of piston head 1, be provided with three seal grooves, in three seal grooves, correspondence arranges seal ring respectively, seal ring near piston head leading section is prime seal ring 7, in the middle of being positioned at is intermediate seal ring 8, seal ring near piston head rearward end is final-stage seal circle 9, the material of described prime seal ring 7 is asbestos, thereby when piston movement, play the effect of immersion oil, the material of middle rank seal ring 8 is also asbestos, further piston is lubricated, prevent the phenomenon of dry friction, final-stage seal circle 9 is guide ring, thereby play the effect of sealing and guiding, the rearward end of piston head 1 is fixedly connected with one end of piston rod 3, the other end of piston rod 3 is provided with spring groove 4, in spring groove 4, be fixedly installed spring 6, described spring groove 4 can be by being processed in piston rod 3 ends, also can use ready-made cell body and piston rod 3 fixedly to make, both sides, the end correspondence of spring groove 4 arranges block 5, described block 5 is detachably fixedly connected with spring groove 4, distance between two blocks 5 is less than the width of spring groove 4, thereby play the effect of fixing spring 6, prevent that spring 6 from coming off from spring groove 4, initiation potential accident.
In the process of work, the leading section of piston head 1 is under the effect of external force, motion, prime seal ring 7 and intermediate seal ring 8 play lubricated effect, and final-stage seal circle 9 leads, and arrive after the terminal of stroke, piston is under the effect of magnetic force and the antagonistic force of impact, do return motion, thereby realize crank motion, carry out lasting rapping.
The utility model discloses bunker wall vibration pneumatic hammer piston, be provided with the magnet that can reset, the prime that can lubricate and seal, intermediate seal ring have been adopted simultaneously, the final-stage seal circle that can lead, the structure design of spring groove has an accident the difficult piston that departs from of spring, has ensured field staff's safety.
