Abstract

The utility model discloses a moving guiding plate of the working roll under the work of the rough rolling mill relating to the rolling machine technical field. The guiding plate is made in perpendicular type. The perpendicular and tail places are provided with pores. The front end is made in sharp type. The pin axis is arranged on the machine frame of the rolling machine. The pin axis is connected with the tail of a syncro-hydraulic cylinder. The front side of the syncro-hydraulic cylinder is connected with an articulated shaft. The articulated shaft is connected with the tail of the guiding plate. The guiding plate is connected with a spinning shaft. The spinning shaft is arranged on the machine frame. When the roll change for the down working roll is needed, the piston of the syncro-hydraulic cylinder is pushed out and the guiding plate is driven into spinning in the center of the spinning shaft by the articulated shaft on top of the hydraulic cylinder. When the working stroke of the syncro-hydraulic cylinder is the biggest, the elevation angle is the biggest, so the removal of the working roll is very convenient and the rapid roll change is realized. When the down working roll after repair grinding is provided again, the syncro-hydraulic cylinder returns, the guiding plate is driven into spinning by the articulated shaft and the elevation angle becomes smaller until at a proper place the syncro-hydraulic cylinder is locked.

Description

The movable guide plate of roughing mill bottom working roll
Affiliated technical field
The utility model relates to the movable guide plate of a kind of roughing mill bottom working roll, belongs to the milling equipment technical field.
Background technology
At present, on operation roll of mill, all adopt fixed guide, therefore after one stage of bottom working roll work, when carrying out reconditioning, need disassemble guide plate simultaneously, so that take out bottom working roll, because the bottom working roll diameter after the reconditioning reduces, needing to reduce the guide plate height could be consistent with bottom working roll, and resting guide needs machining, increases maintenance cost.
Summary of the invention
In order to overcome above-mentioned technical deficiency, the utility model provides a kind of roughing mill bottom working roll movable guide plate, the movable guide plate of this roughing mill bottom working roll realizes that not only exempting to dismantle guide plate changes working roll, and makes guide plate not need machining just can carry out the adjustment of differing heights.
The technical scheme that its technical problem that solves the utility model adopts is: the movable guide plate of roughing mill bottom working roll partly is made up of guide plate, rotating shaft, jointed shaft, synchronous hydraulic cylinder, bearing pin etc., guide plate is made perpendicular type, the boring of place, right angle, afterbody boring, front end is made sharp-pointed type, 25 °-60 ° of angles, bearing pin is fixed on the rolling-mill housing, bearing pin links to each other with the synchronous hydraulic cylinder afterbody, the synchronous hydraulic cylinder front portion links to each other with jointed shaft, jointed shaft links to each other with the guide plate afterbody, and guide plate links to each other with rotating shaft, and rotating shaft is fixed on the frame.The piston of synchronous hydraulic cylinder is released when bottom working roll needs roll change, and the afterbody of synchronous hydraulic cylinder is fixed on by bearing pin and keeps motionless on the frame, and it is the center rotation with the rotating shaft that the top of synchronous hydraulic cylinder drives guide plate by jointed shaft.When the impulse stroke of synchronous hydraulic cylinder reached maximum, bottom working roll can be taken out very easily to maximum in the elevation angle of guide plate at this moment, realizes fast roll changing.When the bottom working roll after the reconditioning reinstall finish after, the synchronous hydraulic cylinder backhaul drives the guide plate rotation by jointed shaft, the elevation angle of guide plate diminishes, and is adjusted to synchronous hydraulic cylinder locking behind the correct position.
The beneficial effects of the utility model are: easy to maintenance, good stability is frequently dismantled guide plate when having avoided the replacing bottom working roll, can alleviate the working strength of service worker; Because guide plate rotation under synchronous hydraulic cylinder drives can realize the adjustment of guide plate differing heights by the different elevations angle of rotation, does not need to process guide plate or pad, reduces cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
