According to the nozzle for quenching provided by the utility model, the distance from the nozzle body to the excircle of the workpiece is always the same by arranging a workpiece surface shape tracking device formed by the slide block, the guide rod, the spring, the chute, the frame with the roller and the like in the device, thereby enhancing the uniformity of surface quenching of the workpiece.
Description
Technical field
The utility model belongs to Machining Technology field, relates in particular to a kind of large-scale metal rotary work piece hard surfacing nozzle.
Background technology
In field of machining, be usually directed to the operation of being quenched in the surface of large-scale metal revolving meber.General large-scale heating and the Special quenching equipment of adopting in existing operating method.These equipment are narrow because of use range such as part dimension, surface shape differences, cause cost high, become thus large-scale steel alloy rotary work piece surface-treated restraining factors.By by the subdivision surfaces of large cylindrical parts bar-shaped zone respectively, progressively quenched and become a kind of feasible scheme in each region circlewise.In prior art, occurred adopting above-mentioned design to the rotating supporting device of revolving meber and quenching nozzle, operating process is to make rotary work piece in the enterprising line stabilization transport of rotating supporting device rotation, adopt nozzle (comprising flame-thrower nozzle and cooling water nozzle) to the workpiece surface processing of quenching, wherein the workpiece surface short period of time is heated to enough high temperature by flame-thrower nozzle, and cooling water nozzle ejection water coolant carries out quench cooled to workpiece surface.For above-mentioned quenching process, comparatively crucial reference mark is the homogeneity of quenching nozzle and workpiece surface distance, only has distance to remain at certain value, and the effect of quenching is just even.And the stability that above-mentioned distance value is rotated by rotating supporting device and nozzle determine the tracking power of workpiece profile, under normal circumstances, rotating supporting device is limited to manufacture and mismachining tolerance always exists certain unstable factor to cause the cylindrical of workpiece to be beated, and quenching nozzle of the prior art does not also have the ability of following the tracks of workpiece profile.
Utility model content
The utility model for solve the technical problem existing in known technology provide a kind of have in the ability, quenching process of following the tracks of workpiece profile keep the large-scale metal rotary work piece hard surfacing nozzle stable with excircle of workpiece spacing.
The utility model for the technical scheme that solves the technical problem that exists in known technology and take is: large-scale metal rotary work piece hard surfacing nozzle comprises with the horizontal pedestal of leading screw, is provided with screw, outer end is provided with and drives termination on described leading screw; Top at described screw is connected with chute, is provided with guide rod horizontal, that be equipped with slide block in described chute, and on described guide rod, wearing promising described slide block provides the spring of reseting elasticity; On described slide block, be connected with horizontal nozzle body, on described slide block, the position concordant with described nozzle body is also provided with the wheel carrier of front end with the roller of metal material.
Advantage of the present utility model and positively effect are: quenching of the present utility model with nozzle by the workpiece surface shape tracking device forming by slide block, guide rod, spring, chute and with the support of roller etc. is set in device, make the distance between nozzle body and excircle of workpiece remain consistent, promoted the homogeneity that workpiece surface quenches.
Preferably: described nozzle body adopts pressing plate to be fixed on described slide block.
Preferably: on described slide block, be provided with the connecting hole of lateral direction penetrating, described nozzle body is pegged graft and is fixed on described connecting hole.
Brief description of the drawings
Fig. 1 is main TV structure schematic diagram of the present utility model and part sectioned view;
Fig. 2 is the plan structure schematic diagram of the utility model nozzle segment;
Fig. 3 is the front view of use state of the present utility model.
In figure: 1, nozzle body; 2, wheel carrier; 3, slide block; 4, roller; 5, guide rod; 6, chute; 7, screw; 8, pipeline; 9, spring; 10, leading screw; 11, pedestal; 12, drive termination; 13, rotary work piece.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1 and Fig. 2, the utility model comprises the pedestal 11 with horizontal leading screw 10, on leading screw 10, being provided with screw 7, outer end is provided with and drives termination 12, by external drive unit as handwheel, step-down gear (belt or chain gear) etc., drive leading screw 10 to rotate, position that can lateral adjustments screw 7.
Be connected with chute 6 at the top of screw 7, be provided with guide rod 5 horizontal, that be equipped with slide block 3 in chute 6, on guide rod 5, wearing promising slide block 3 provides the spring 9 of reseting elasticity.
On slide block 3, be connected with horizontal nozzle body 1, on slide block 3, the position concordant with nozzle body is also provided with the wheel carrier 2 of front end with the roller 4 of metal material.
Above-mentioned chute 6, guide rod 5, spring 9 and the wheel carrier 2 with roller 4 have formed the tracking device that workpiece 13 surface shapes are followed the tracks of, roller 4 holds out against on workpiece 13 surfaces, roller 4 its surperficial change of shape of induction when workpiece 13 rotates, make nozzle body 1(comprise flame-thrower nozzle and cooling water nozzle) and workpiece 13 surfaces between distance remain unchanged, directly promoted the hard-faced homogeneity of workpiece 13.When actual installation, wheel carrier 2 should be between flame-thrower nozzle and cooling water nozzle.
In this example, nozzle body 1 can be adopted in two ways and be fixed with slide block 3.The one, adopt pressing plate to be fixed on slide block 3, be now directly connected to the rear end of nozzle body 1 for delivery of the pipeline 8 of gas and water coolant; The 2nd, the connecting hole of lateral direction penetrating is set on slide block 3, nozzle body 1 is pegged graft and is fixed on this connecting hole, as adopt the affixed or mode such as be threaded of welding, now must plug the connecting joint that is fixed for connecting pipeline 8 in the outer end of connecting hole, connecting joint also adopt welding affixed or be threaded etc. mode and slide block 3 affixed.
Fig. 3 is use state graph of the present utility model.Can find out, workpiece 13(rope sheave) under the drive of rotating supporting device, do at the uniform velocity to turn round, this quenching is arranged on workpiece one side with nozzle, nozzle body 1 and wheel carrier 2 stretch in the annular recesses on workpiece 13 surfaces, roller 4 and the surperficial variation that is affixed perceived shape, flame-thrower nozzle carries out calcination to workpiece, and cooling water nozzle carries out quenching to workpiece, realizes the processing of quenching.
Shape that it should be noted that nozzle body 1 front end should be chosen according to the type of workpiece 13, and when having continuous formation surperficial when workpiece 13, the front end of nozzle body 1 should be also straight.
