Abstract
A quick working roll overturning device for a drawing and strengthening machine comprises a base, a frame structure and an overturning support, wherein the frame structure comprises a fixing frame for bearing a working roll of the drawing and strengthening machine, and brackets extending out of the two ends on one side of the fixing frame; the overturning support comprises a two fixing blocks and an overturning shaft; the overturning shaft is arranged on the fixing frame of the base; the two fixing blocks are connected to the end part of the overturning shaft on the outer side of the fixing frame and turn over by taking the overturning shaft as an axial core; and fixing grooves for fixing shaft heads at the two ends of the working roll of the drawing and strengthening machine are formed in the two fixing blocks. The quick working roll overturning device for the drawing and strengthening machine can turn over the working roll quickly, increase the speed of changing the working roll of the drawing and strengthening machine greatly, reduce manual operating link during the roll changing operation, reduce labor intensity and improve working efficiency.
Description
Technical field
The utility model relates to straightening machine workroll change, relates in particular to a kind of quick turn-over rig of straightening machine working roll
Background technology
Hot-strip needs to carry out scale breading and plate shape aligning as last carrying out pickling, and the iron oxide cortex with the belt steel surface densification breaks on the one hand, is convenient to follow-up pickling; Reduce the shape wave of hot rolling motherboard on the other hand, be follow-up rolling creating conditions.
The scale breading method for aligning that the pickling unit is commonly used is to use stretching-bending straightener at present, abbreviates the straightening machine as, and it is made up of bending roll group and smoothing roll group.The bending roll group is made up of top working roll and bottom working roll again.Straightening machine working roll surface in use for some time can wear and tear, and influences leveling effect, needs to change working roll this moment.During roll change, use trailer wagon that upper and lower working roll is pulled out in frame, old roller hangs, and changes new roller.But because the working face of straightening machine top working roll is downward, can't directly land, at first need when therefore changing the top working roll turn-over.Existing method is to rely on driving and assembly pulley to cooperate turn-over.But there are the following problems for this method:
Straightening machine turn-over need be employed the major and minor hook of driving simultaneously, and use assembly pulley, many people coordinating operation, consuming time longer, working roll of average replacing needs consuming time more than 1 hour, and the two curved one straightening machines of rectifying structures common with cold rolling product line are example, all change about 3 hours consuming time at least of 4 working rolls, and labour intensity is beaten, and has higher potential safety hazard in the operation process.
Summary of the invention
The purpose of this utility model designs the quick turn-over rig of a kind of straightening machine working roll, can finish the work the fast turn-over of roller, can improve the roll change speed of straightening machine working roll greatly, and reduce the manual work link in the roll change operation, increase work efficiency when reducing labour intensity.
For achieving the above object, the technical solution of the utility model is:
The quick turn-over rig of a kind of straightening machine working roll, it comprises, base, frame structure comprises the fixed mount that is used to carry straightening machine working roll, the carriage that stretches out from the two ends of fixed mount one side and form; Turnover bracket comprises two fixed blocks and trip shaft; Trip shaft is arranged on the described base fixed mount, and two fixed blocks are connected in the trip shaft end in the described fixed mount outside, is that upset is realized in the axle center with the trip shaft; Offer the fixedly fixed groove of straightening machine working roll two ends spindle nose on two fixed blocks respectively.
Further, offer fixed pin holes on described two fixed blocks vertically respectively, two stop pins are by fixed pin holes and pass working roll spindle nose in the fixed groove, and the working roll spindle nose is locked in the fixed block fixed groove.
In addition, base fixed mount described in the utility model comprises base plate and is positioned at two fixed supports of base plate upper surface that described carriage stretches out from the two ends of base plate one side and upwards bends and forms.
The cushion pad of the impulsive force when establishing buffering turnover bracket whereabouts on the described carriage.
Described cushion pad adopts polyurethane material.
During work, straightening machine working roll is hung on turnover bracket, lock stop pin; On the suspension ring of working roll side, fix steel wire rope, with the driving lifting; Working roll one-sided stressed after, be to overturn clockwise in the axle center with the trip shaft, command the travelling crane hook translation simultaneously, it is the axle center upset that turnover bracket is continued with the trip shaft; After flip angle surpassed 90 °, commander's travelling crane hook put down, and working roll is finished turn-over; Extract stop pin,, remove steel wire rope, finish whole operations the turnover bracket playback.
The beneficial effects of the utility model
The utility model has been abandoned complicated in the past loaded down with trivial details assembly pulley turn-over flow process, by turnover bracket, trip shaft, stop pin, and can be by easily the finish the work turn-over of roller of the main structure of driving a vehicle.This apparatus structure is simple, with low cost, easy to operate, it is standby working roll can be shifted to an earlier date turn-over before the formal replacing of straightening machine, can effectively shorten the roll change time of straightening machine, through the on-the-spot actual checking of using, every working roll replacing time can be foreshortened in 20 minutes, also significantly improved operating efficiency when reducing operation intensity.
