Description

Continuous casting steel billet dummy bar centering top fast replacing device
Technical field
The utility model relates to a kind of metallurgy industry continuous casting steel billet dummy bar centralising device, belongs to the continuous casting installation for casting technical field.
Background technology
In conticaster, the effect of dummy bar is dummy ingot and throwing, in last dummy ingot process, often occur since on behind the dummy ingot dummy bar misalign the situation that the influence that caused produces and take place.The lighter will scratch copper plate of crystallizer, weigh the serious production accident that will cause pushing up bad crystallizer.At this kind situation, iron and steel enterprise's extensive use at present crystallizer dummy bar centralising device.Centralising device generally adopts hydraulic pressure or mechanical drive standard top to realize radially motion in one dimension of dummy bar, the final effect that arrives the adjusting dummy bar.
Time all dummy bar is regulated owing to water whenever to water before the steel, the centralising device top is used frequent.According to watering in average every month 40 time, whenever water and time regulate 6 times and calculate top year bump dummy bar number of times nearly three over thousands of times.Cause bump harm to consider that the top of general centralising device is selected the metal material softer than dummy bar for use from reducing to dummy bar simultaneously.Thereby the replacing problem after the wearing and tearing of centralising device top becomes particularly outstanding.
The top of general centralising device is connected with push rod all adopts welding manner to connect or the mechanical system connection, this kind connected mode is brought inconvenience to changing the top, nearly 10 hours once consuming time of average replacing even longer time, cause more serious time waste, be unfavorable for improving caster work rate.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of prior art defective that overcomes, while easy operating, the continuous casting steel billet dummy bar centering top fast replacing device of being convenient to safeguard.
The technical scheme that solves the problems of the technologies described above is:
A kind of continuous casting steel billet dummy bar centering top fast replacing device, it is by pedestal, motor, decelerator, leading screw, screw, the tailstock main shaft, the tailstock rack sleeve, the tailstock push rod, outer-hexagonal screw and hex nut are formed, motor, decelerator, the tailstock rack sleeve is fixedly mounted on the pedestal, motor is connected with leading screw by decelerator, screw is meshed with leading screw, the tailstock main shaft is installed in the tailstock rack sleeve, screw is connected with the tailstock main shaft, the tailstock push rod is installed in the front end of tailstock main shaft, the front end of tailstock push rod is connected with outer-hexagonal screw and hex nut, and the tailstock push rod adopts Morse's taper to be connected with hex nut.
Above-mentioned continuous casting steel billet dummy bar centering top fast replacing device, described motor has the encoder control device.
Above-mentioned continuous casting steel billet dummy bar centering top fast replacing device, described decelerator is made up of reductor, reductor end shaft coupling, and reductor end shaft coupling is connected with leading screw end shaft coupling by the shaft coupling buffering ring.
Adopt the continuous casting steel billet dummy bar centering top fast replacing device of this structure, reach dummy bar accurately location and the quick top of changing by driven by motor leading screw, tailstock push rod, the motion of outer-hexagonal screw that has encoder.The advantage that this device has is simple in structure, easy to use, regulate accurately and fast, be convenient to safeguard, what solved the continuous casting steel billet dummy ingot changes the problem that the top exists to neutralization, and good benefit is arranged, and is worth of widely use.
Description of drawings
Fig. 1 is the installation site schematic diagram of the present invention on the slab roller-way;
Fig. 2 is a structural representation of the present invention.
Mark is as follows among the figure: outer-hexagonal screw 1, hex nut 2, tailstock push rod 3, tailstock main shaft 4, tailstock rack sleeve 5, leading screw 6, screw 7, tailstock main shaft bonnet 8, tailstock rack sleeve flange 9, soket head cap screw 10, leading screw end shaft coupling 11, shaft coupling buffering ring 12, reductor end shaft coupling 13, reductor 14, key 15, taper pin 16, pedestal 17.
The specific embodiment
Show among the figure that the utility model is made up of pedestal 17, motor, decelerator, leading screw 6, screw 7, tailstock main shaft 4, tailstock rack sleeve 5, tailstock push rod 3, outer-hexagonal screw 1, hex nut 2.Motor, decelerator, tailstock rack sleeve 5 are fixedly mounted on the pedestal 17, motor is connected with leading screw 6 by decelerator, screw 7 is meshed with leading screw 6, tailstock main shaft 4 is installed in the tailstock rack sleeve 5, screw 7 is connected with tailstock main shaft 4, tailstock push rod 3 is installed in the front end of tailstock main shaft 4, and the front end of tailstock push rod 3 is connected with outer-hexagonal screw 1 and hex nut 2, and tailstock push rod 3 adopts Morse's taper to be connected with hex nut 2.
It is power that the utility model adopts motor, utilizes encoder accurately to control the motor revolution, uses leading screw 7 to drive screw 7 relative motions, and realization tailstock main shaft 4 is located on the width of plate slab direction.Adopt the Morse's taper connected mode to realize the fast-assembling quick change of top simultaneously.
The utility model is when work, and reductor 14 is under the driving of power source at the motor that has encoder, is connected with leading screw end shaft coupling 11 with shaft coupling buffering ring 12 by reductor end shaft coupling 13.Motor rotating band movable wire thick stick 6 rotates, and realizes that screw 7 and tailstock main shaft 4 seesaw, and realizes axial accurate location at the tailstock push rod 3 drive outer-hexagonal screws 1 that tailstock main shaft 4 front ends are settled, and finally finishes the location to dummy bar.
When 2 wearing and tearing of outer-hexagonal screw 1 and hex nut maybe need to change, backward rotation driven by motor leading screw 6 backward rotation, tailstock push rod 3 shrinks, realize that tailstock push rod 3 and tailstock rack sleeve 5 produce relative displacement, after tailstock push rod 3 reaches the limit of the position, because tailstock push rod 3 adopts Morse's taper to be connected with hex nut 2, tailstock push rod 3 produces with tailstock rack sleeve 5 and continues relative displacement, this moment, 3 continuation of tailstock push rod were shunk, and then outer-hexagonal screw 1 and hex nut 2 ejected, realized the fast-assembling quick change.
