Embodiment
Core of the present utility model provides a kind of spray air-cooling device, and this spray air-cooling device can adapt to the quenching of the various rail spares of track switch, need not to change, and need not to regulate highly versatile.
In order to make those skilled in the art person understand better the utility model scheme, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
It is pointed out that the upper and lower noun of locality that waits that this paper is related, is to be arranged in figure and component position each other defines with component among Fig. 1 to Fig. 3, just in order to explain the clear of technical scheme and conveniently.Should be appreciated that the noun of locality that this paper adopts should not limit the scope that present specification is asked for protection.
Please refer to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 provides the front view of a kind of embodiment of spray air-cooling device for the utility model; Fig. 2 is the upward view of the air-cooling device of spray shown in Fig. 1; Fig. 3 is the structural representation of a kind of embodiment of high speed air blast beak of the air-cooling device of spray shown in Fig. 1.
In a kind of embodiment, railroad turnout steel rail spare quenching spray air-cooling device provided by the utility model comprises the more piece casing that joins successively; Can be mounted with by the first seal washer 41 and holding bolt 51 between the described casing, can certainly fix by other fixed forms.
The joint number of described casing is determined according to the process speed that quenches in the reality and required speed of cooling, is preferably two joint casings or three joint casings.
Described casing comprises upper box 11 and lower box 12, can be mounted with by the second seal washer 42 and fitting nut 52 between described upper box 11 and the described lower box 12.
The upper end face of described upper box 11 is furnished with a plurality of pressurized air air intake joints 2, and pressurized air air intake joint 2 is connected with compressed air line.Described pressurized air air intake joint 2 can be welded and fixed with described upper box 11, also can be connected and fixed by screw; Particularly, described pressurized air air intake joint 2 is evenly arranged at the upper end face word order of described upper box 11, arranges like this, can be so that pressurized air evenly distributes in casing.Certainly, the layout of pressurized air air intake joint 2 also can adopt other forms, evenly distributes in casing as long as can guarantee pressurized air.
The bottom surface of described lower box 12 is furnished with high speed air blast beak 3, the bottom surface at right angle setting of described high speed air blast beak 3 and described lower box 12.Particularly, can be mounted with seal washer and fitting nut between the box plate of described high speed air blast beak 3 and described lower box 12, can certainly use other modes.It is to be noted, because being used for spray wind, high speed air blast beak 3 cools off heated railroad turnout steel rail spare, the temperature of heated railroad turnout steel rail spare is higher, so the seal washer between the box plate of high speed air blast beak 3 and described lower box 12 preferably adopts the seal washer of heatproof, prevent that the seal washer that causes because railroad turnout steel rail spare temperature is high from damaging, and then impact spray wind cooling effect.
Described high speed air blast beak 3 is preferably streamlined high speed air blast beak; Streamlined high speed air blast beak has that the pressurized air consumption is little, cooling power is strong and cool off the advantages such as even.The inner chamber of streamlined high speed air blast beak is streamlined cavity, and when work, pressurized air enters the trunnion of high speed air blast beak by streamlined cavity, and then high-velocity jet is in the surface of work piece.
Described high speed air blast beak 3 at the bottom surface of described lower box 12 with the mode of the chessboard type structure layout that misplaces, can certainly be with other arrangement.Because the diameter of high speed air blast beak 3 is larger, the spacing that can shorten between the high speed air blast beak 3 is arranged in the chessboard type structure dislocation, thereby the working face of railroad turnout steel rail spare is cooled off uniformly and effectively.
In actual the setting, can change by the aperture of the spacing between the adjustment high speed air blast beak 3 and high speed air blast beak 3 cooling power and the speed of cooling of spray air-cooling device, to satisfy the quenching demand of different types of railroad turnout steel rail spare.
In order to guarantee that this spray air-cooling device goes for various types of railroad turnout steel rail spares, the bottom width of described spray air-cooling device is the width that the real work width of high speed air blast beak 3 has been contained the widest existing rail spare section.
During work, when the working face of track switch rail spare is heated the inductor block heating, during the regional steel body of its working face generation complete austenitizing phase transformation, adopt the working face of spray air-cooling device cooling railroad turnout steel rail spare provided by the utility model, particularly, can regulate as required the bottom surface of this spray air-cooling device and the angle between the railroad turnout steel rail spare working face, the compressed air line of pressurized air enters in the casing by pressurized air air intake joint 2, and enter trunnion by the streamlined cavity of high speed air blast beak 3, then with the working face of proper angle high-velocity jet in rail spare, it is to be noted, the proper angle here refers to the bottom surface of above-mentioned spray air-cooling device and the angle between the railroad turnout steel rail spare working face, can determine according to reality is required, preferred angular range is 45 degree ~ 125 degree.Through the spray wind cooling of spray air-cooling device, can make rail spare working face austenite occur to the nodular troostite structural transformation in the perlitic transformation zone, and other structural transformation such as bainite and martensite does not occur.
It is pointed out that the pressurized air blast of spray air-cooling device and speed of cooling etc. can be according to processing request and actual required settings of railroad turnout steel rail spare in spray wind cooling process.
Spray air-cooling device provided by the utility model has been cancelled both sides horizontal direction spray air-cooling device, only has vertical spray wind cooling, the quenching spray that can adapt to dissimilar rail spare is cold, the rail spare of variable cross-section particularly, compared with prior art, for different types of rail spare, do not need to reconfigure air blast beak, do not need to regulate highly versatile, good cooling results yet.
Here it is pointed out that except above-mentioned railroad turnout steel rail spare, spray air-cooling device provided by the utility model is applicable to the spray wind cooling of similar board-like part too.
Above spray air-cooling device provided by the utility model is described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
