Description
The application is a kind of cooling device of entitled pneumatic nail gun cushion pad, Application No. 2015102277511,
The applying date is the divisional application of on 05 06th, 2015.
Technical field
The invention belongs to pneumatic tool technical field, it is related to a kind of pneumatic nail gun, more particularly to a kind of pneumatic nail gun buffering
The cooling device of pad.
Background technology
Pneumatic nail gun can be used for container pallet, large-scale wooden packing box manufacture fence, house timber structure connection, it is wooden
The connection of furniture and other wooden structures.Can quickly stitching, saving labour cost.
Existing pneumatic nail gun, such as Chinese patent literature data disclose the pneumatic nail with cement timber double-purpose functional
Rifle [the patent No.：02241710.9；Authorization Notice No.：CN2550136Y], it includes housing, cylinder, cylinder head, balanced valve, rifle
Lid, pipette tips, striker, nail kit, trigger piece, suction nozzle, are provided with a cushion pad between cylinder and housing, there is one between housing and cylinder head
Individual O-ring seal, there is a back-moving spring between balanced valve and cylinder head, has frizzen to constitute insurance dress with trigger piece in pipette tips
Put, there is muscle to be divided into different intervals on the guide nail slot that pipette tips and nail kit are constituted.
This kind of pneumatic nail gun of structure, when compressed air imports gun body from suction nozzle, pulls trigger piece and makes touching in pipette tips
Hair bar is pressed on stitching thing, and the now valve-closing at balanced valve rear portion, balanced valve and cylinder leave, and compressed air quickly enters gas
In cylinder, the nail afterbody in striker impact nail kit is promoted, project nail, to reach with the purpose of nail articles；It is pneumatic
When in use, usually continual to launch many nails, cushion pad is made up nail gun of elastomeric material, every time in nail
During injection, striker can all clash into cushion pad, and the cushion pad after being hit can deform, and cushion pad comes from by self-deformation alleviation and hits
The impact of pin, can produce heat in deformation process, and be a closed cavity in the housing of pneumatic nail gun, what collision was produced
Heat can not be dispersed into the external world, and collision can make cushion pad heat up, and accelerate the aging of cushion pad, accelerate the damage of cushion pad, buffering
Pad service life is short, once cushion pad is damaged, may result in product function failure, it is necessary to look for professional or to specialized maintenance point
Changed, changed trouble.
The content of the invention
The purpose of the present invention is directed to the above-mentioned problems in the prior art, it is proposed that a kind of pneumatic nail gun cushion pad
How cooling device, solution improves the service life of existing pneumatic nail gun cushion pad.
The purpose of the present invention can be realized by following technical proposal：A kind of cooling device of pneumatic nail gun cushion pad, gas
Dynamic nail gun includes housing, and the cavity in the housing is connected with suction nozzle, and the cushion pad is located in housing, and its feature exists
In, the cooling device includes cooling tube, cooling bucket one and cooling bucket two, and middle part and the cushion pad of the cooling tube fit,
Piston one is provided with the cooling bucket one, the piston one will cool down one point of bucket for mutually disconnected pneumatic cavity and liquid storage up and down
Chamber, the pneumatic cavity is connected with the cavity of housing, and the liquid storage cylinder is connected with one end of cooling tube, the cooling tube it is another
One end is connected with cooling bucket two, and being provided with the cooling bucket two can be such that coolant is back to from cooling bucket two in cooling bucket one
Resetting structure.
This cooling device is that cushion pad is cooled down by coolant, and when in use, gas passes through air inlet to pneumatic nail gun
Mouth is entered into the cavity of housing, and high pressure is formed in the cavities, by striker impact nail, realizes the purpose of nailing, Er Qiekong
Gases at high pressure in chamber can be entered into the pneumatic cavity of cooling bucket one, and gases at high pressure promote piston one to move down, and make to be located at liquid storage cylinder
In coolant along cooling tube flow to cooling bucket two in, the time of nailing of pneumatic nail gun is very short, after a nailing, shell
The air pressure reduction of internal cavity, the i.e. air pressure of pneumatic cavity is also reduced, and now resetting structure work makes the coolant in cooling bucket two
Backflow, is returned in the liquid storage cylinder for cooling down bucket one by cooling tube, and coolant is taken away cushion pad and hit during reciprocal flowing
The heat produced during deformation is hit, cushion pad is maintained at suitable temperature, cushion pad is non-aging, be hardly damaged, cushion pad makes
With long lifespan, pneumatic nail gun long service life.
In a kind of cooling device of above-mentioned pneumatic nail gun cushion pad, spring one, the bullet are provided with the liquid storage cylinder
