Description
Technical field
the present invention relates to aluminium process equipment, specifically a kind of for changing the changing rig of cold rolling mill work roller.
Background technology
After cold-rolling mill work a period of time, working roll can wear and tear, and causes board quality defect, the working roll that now will more renew.During work roll changing, lead spindle is held tightly fixingly by spindle carrier, with roll changing carriage, working roll is pulled out, and then new working roll is pushed in lead spindle spindle nose, completes a roll change.Roll changing carriage is in the past simple in structure, and roll changing time is long, and more difficult the pushing of new working roll puts in place, often need to hang with traveling crane.The whole roll change process time consuming time is long, thereby has reduced production efficiency.
Summary of the invention
technical problem to be solved by this invention is: a kind of cold rolling mill work roller changing rig that can change the working roll of cold-rolling mill is rapidly provided.
Technical scheme of the present invention is: a kind of cold rolling mill work roller changing rig, it comprises cart device, roll change buggy device, described cart device comprises large vehicle frame, cart wheel, power-driven mechanism, described cart device be seated in longitudinal setting, be fixedly mounted on the large Car Track on ground, between described large vehicle frame and large Car Track, be provided with and can carry out spacing cart stopping means to large vehicle frame; Described roll change buggy device comprises little car body, hook, the power-driven mechanism that can articulate with working roll or depart from; Between cart device and roll change buggy device, be also provided with middle car device, described middle car device comprises middle vehicle frame, Power Drive Unit; On described large vehicle frame, be provided with laterally extending, can supply in the middle Car Track of car device walking; On described middle vehicle frame, be provided with two and be respectively used to place station new, old working roll, on described each station, be provided with roll change buggy track extending longitudinally, that can walk for roll change buggy device; Described middle vehicle frame longitudinally rear is also provided with one section of energy is aimed at different station return trajectory along with the transverse shifting of middle vehicle frame.
The bottom of described middle vehicle frame is provided with middle car wheel, and described middle Car Track matches with middle car wheel.
Between described roll change buggy device and roll change buggy track, adopt rack-and-pinion transmission.
The both sides of described little car body are respectively arranged with roller, and the both sides of described roll change buggy track are provided with the stopper slot matching with described roller.
Between described middle vehicle frame and large vehicle frame, be provided with and can carry out spacing middle car stopping means by centering vehicle frame.
Advantage of the present invention is: change original car body into large vehicle frame and middle car movable stand, and on middle car movable stand, increase the station that can place new roller, in moving, car movable stand moves on to operating position by new roller, old roller is shifted out to operating position simultaneously.With roll change buggy, pull out old roller, then new roller is pushed in lead spindle spindle nose.Whole roll change process time is short, easy to operate, thereby has greatly improved production efficiency.
