Detailed description of the invention
Core of the present invention is to provide a kind of roll-separating mechanism of milling train guide and guards, can strengthen the versatility of guide and guards, thus improves steel rolling efficiency.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, Fig. 1 is the overall structure schematic diagram of milling train disclosed in the embodiment of the present invention, and Fig. 2 is the structural scheme of mechanism of driving mechanism disclosed in the embodiment of the present invention.
The roll-separating mechanism of milling train guide and guards disclosed in the present invention comprises:
Lower guide roll support, lower guide roll, upper guide roller support, upper deflector roll, as shown in fig. 1, the two ends of lower guide roll support are connected with bottom bearing block 1 respectively, and lower guide roll is arranged in lower guide roll support rotationally; Upper guide roller support is corresponding with lower guide roll support to be arranged, and the two ends of upper guide roller support are connected with upper shaft bearing 2 respectively, and upper deflector roll is arranged on guide roller support rotationally.Wherein, bottom bearing block 1 and/or upper shaft bearing 2 are threaded on rotating leading screw 3, and leading screw 3 is also connected with driving the driving mechanism himself rotated.
In the above-described embodiments, bottom bearing block 1 and upper shaft bearing 2 can all be arranged on leading screw 3, the rotation direction of the screw thread in such cases leading screw 3 matched with upper shaft bearing 2 and bottom bearing block 1 should be contrary, with ensure both can realize close to each other and mutual away from; Also can upper shaft bearing 2 be fixed bearing block, bottom bearing block 1 be arranged on leading screw 3; Or bottom bearing block 1 is fixed bearing block, and upper shaft bearing 2 is arranged on leading screw 3.
Understandablely be, driving mechanism drives leading screw 3 to rotate, leading screw 3 forms screw slider mechanism, rotating and reverse of leading screw 3 with upper shaft bearing 2 and/or bottom bearing block 1, and upper shaft bearing 2 and/or bottom bearing block 1 can be driven to move up and down along the axis of leading screw 3.This by guide roller support in drive away from or near lower guide roll support, the guiding clearance of thus go up between deflector roll and lower guide roll also just becomes greatly thereupon or diminishes.As can be seen here, roll-separating mechanism disclosed in above-described embodiment, achieves the change of guiding clearance between lower guide roll, and thus guide and guards can lead to the steel of the different plurality of specifications of model, effectively improves the versatility of guide and guards.
Certainly, the guide and guards mentioned in the present invention includes but not limited to round steel guide and guards and guide for steel flat device.
As can be seen from Fig. 1, leading screw 3 comprises two, the upper shaft bearing 2 of the two corresponding left and right sides of rhizoid thick sticks 3 difference and bottom bearing block 1.Driving mechanism can be two drive motors 4, and these two drive motors 4 are connected with two leading screws 3 respectively.
