This device efficiently improves the quenching treatment efficiency of the steel rail end. It has the advantages of having a strong self-adaptive ability and improving quenching quality.
Description
The utility model belongs to the thermal treatment field, relates to a kind of steel rail end servo-actuated quenching device.
In the prior art, steel rail end is carried out the fixed quenching press of hat quench treatment, be that the stepping pusher is delivered to rail before the fixed quenching press behind the prescribed position on the processing stand, the ability translation reaches steel rail end quenching zone and heats → soaking → quenching process, and then steel rail end is withdrawed from translation, by the stepping machine for moving steel it is pushed away away, and another rail is pushed prescribed position before the fixed quenching press, repeat above-mentioned quenching process.Adopt fixed quenching press that steel rail end is carried out the hat quench treatment and have following problem:
It is 1. online that steel rail end is carried out the quench treatment cycle is long;
2. the accuracy requirement that rail is put in place is very high, otherwise water cooler can directly be broken by rail;
3. quenching press can not carry out the self-adaptation adjustment to loxosis steel rail end quenching position.
The purpose of this utility model is to propose the steel rail end servo-actuated quenching device of a kind of press quenching efficient height, energy self-adaptation adjustment quenching position.
According to the purpose of utility model, the utility model proposes following technical scheme:
Steel rail end servo-actuated quenching device comprises cant cantilever, column, water cooler, servo-actuated dolly, hoisting appliance, fixing catch, active card, loopback mechanism and slide rail etc.Column is fixed on the ground, and cant cantilever is installed on the column.Horizontal two slide rails that connect between two cant cantilevers, the servo-actuated dolly is placed on the slide rail.Hoisting appliance is contained on the servo-actuated dolly, and its elevating lever lower end is connected to fixing catch and active card.Water cooler is installed in the outer end of active card.Loopback mechanism is connected with the servo-actuated dolly.
Loopback mechanism in the above-mentioned steel rail end servo-actuated quenching device is made up of motor, speed reduction unit, screw mandrel and slide block.Speed reduction unit go into end and motor shaft coupling, the other end and screw mandrel shaft coupling.Slide block set is connected on the screw mandrel.
Adopt the steel rail end servo-actuated quenching device of technique scheme, have following advantage:
1. shorten the work period, improved at least one times of working efficiency;
2. water cooler has stronger order adaptive faculty, has improved the quality that steel rail end quenches;
3. avoided steel rail end to break the accident of water cooler.
Below, the utility model is described in further detail in conjunction with the accompanying drawings:
Accompanying drawing 1 is the synoptic diagram of the utility model embodiment;
Accompanying drawing 2 is the vertical view of the utility model embodiment;
Accompanying drawing 3(a) be that the A of accompanying drawing 1 is to view;
Accompanying drawing 3(b) be accompanying drawing 3(a) sectional view.
Embodiment 1, and steel rail end servo-actuated quenching device comprises servo-actuated dolly 1, hoisting appliance 2 fixing catch 3, active card 4, cant cantilever 5, slide rail 6, loopback mechanism 7, water cooler 8 and column 9.Column 9 is fixed on the ground, and its upper end is equipped with cant cantilever 5.Horizontal two slide rails 6 that are connected between two cant cantilevers 5, servo-actuated dolly 1 is placed on the slide rail 6.Hoisting appliance 2 is contained on the servo-actuated dolly 1, and its elevating lever 10 lower ends are connected to fixing catch 3 and active card 4.Water cooler 8 is contained in the outer end of active card 4.Loopback mechanism 7 is connected with servo-actuated dolly 1.
Embodiment 2, and steel rail end servo-actuated quenching device comprises servo-actuated dolly 1, hoisting appliance 2 fixing catch 3, active card 4, cant cantilever 5, slide rail 6, loopback mechanism 7, water cooler 8 and column 9.Column 9 is fixed on the ground, and its upper end is equipped with cant cantilever 5.Horizontal two slide rails 6 that are connected between two cant cantilevers 5, servo-actuated dolly 1 is placed on the slide rail 6.Hoisting appliance 2 is contained on the servo-actuated dolly 1, and its elevating lever 10 lower ends are connected to the outer end that fixing catch 3 and active card 4 water coolers 8 are contained in active card 4.Loopback mechanism 7 is made up of motor 11, speed reduction unit 12, screw mandrel 13 and sliding shoe 14.Speed reduction unit 12 is gone into end and motor 11 connecting shafts, the other end and screw mandrel 13 connecting shafts.Sliding shoe 14 is socketed on the screw mandrel 13.Whole loopback mechanism 7 is installed on the cant cantilever 5.
During work, before the stepping machine for moving steel on the processing stand is delivered to the induction heating device of quenching press with rail.Its induction heating device moves forward, and makes steel rail end enter the induction heating device internal heating along guide plate.When steel rail end was heated to specified temperature, induction heating device stopped heating, and withdraws from steel rail end, makes its air cooling.Meanwhile, hoisting appliance 2 on the servo-actuated dolly 1 promotes its elevating lever 10 and moves down under the control of hydraulic efficiency system, till fixing catch 3 and active card 4 are blocked rail's end portion, water cooler 8 covers on the heated rail's end portion of steel rail end reliably, and active card 4 is adjusted the optimum position that the steel rail end hat quenches adaptively.The stepping machine for moving steel begins to promote rail and moves forward, and moves forward by fixing catch 3 drive active card 4, water cooler 8, hoisting appliance 2 and the servo-actuated dolly 1 that is stuck in rail's end portion.In the rail moving process, water cooler 8 ejection heat-eliminating mediums are finished the quench treatment to arc steel rail end hot spots.After the stepping machine for moving steel was delivered to the position with hard-tempered rail, before second rail shifted induction heating device onto again, meanwhile, hoisting appliance 2 upgraded fixing catch 3, active card 4 and water cooler 8; Motor 11 startup portions drive sliding shoe 14 by speed reduction unit 12 and screw mandrel 13 and send the servo-actuated dolly back to original position.After second steel rail end heating, the servo-actuated quenching device repeats an above-mentioned work period again, finishes the quench treatment to steel rail end.
