[0002] At present, various equipment and measures have been adopted for the transportation of billets and the cleaning of tailings before cold shearing, but none of them can solve the problem of tailings cleaning purely mechanically. Most steel mills still rely on manual assistance for tailings cleaning. The main reason is that the space before cold shearing is limited. Not only is the steel pressing device arranged, but also piping and slag baffles are provided. The equipment in front of the cold shearing machine must not only lift and transport the billets on the table in front of the shearing machine blade, but also cannot lift the billets in the air during shearing. When feeding without shearing, the roller group is lifted to a high position, and the distance between the lifted billet and the shearing machine table and the shearing blade needs to be a certain size to reduce the friction of the billet and the wear of the equipment. When shearing is required, the roller group before shearing stops running and dives under the shearing machine table. The steel pressing presses the material to be sheared tightly against the table and the lower shearing edge to implement shearing. When shearing is completed, the conveying roller group needs to be immediately lifted and operated to transport the material forward to keep the shearing machine running efficiently.

[0003] Therefore, there is an urgent need for a floating roller device that can mechanized and efficiently solve the problem of tail material cleaning and efficiently cooperate with the cold shearing machine to transport the blanks. Utility Model Content

The utility model provides a floating roller structure with three groups of rollers arranged infinitely closely. The fully automated mode of lifting the blank and driving it forward is realized by the disc spring floating roller group. The shearing and conveying roller system is pressed down and sunk flush with the lower blade. After shearing, the spring quickly and automatically floats and resets, and the power roller drives the lifting and conveying forward to remove the tail of the material.

[0005] The utility model discloses a pull-out type floating roller device, which comprises a floating roller, both ends of which are fixed to a frame through roller bearing seats, a guide wheel is installed at the lower end of the frame, a guide rail which slides with the guide wheel is arranged at the lower end of the guide wheel, the guide rail is fixed to the cold shearing machine, one end of the guide rail is also detachably fixedly connected to the frame, a motor is connected to one end of the frame, the floating roller is connected to the motor through a transmission shaft, and drives the floating roller to rotate.

The number of disc springs 5 ​​set in the roller bearing seat 11 can be matched according to the size of the roller. In the utility model, since the size of the active roller 2 and the driven roller 3 is larger than the free roller, the number of disc springs 5 ​​set at the lower ends of the active roller 2 and the driven roller 3 can be two groups.

[0025] According to the embodiment of the utility model, the active roller 2, the driven roller 3 and the free roller 4 of the utility model have different radial dimensions. The active roller 2 and the driven roller 3 have the same dimensions, while the radial dimension of the free roller 4 is smaller than that of the other two. Therefore, although the axial center lines of the three are not on the same horizontal plane, the straight lines corresponding to the uppermost ends of the three are on the same horizontal plane, which can ensure smooth transportation of the blank during transportation through the three rollers.

[0026] According to an embodiment of the utility model, the floating roller includes an active roller 2, a driven roller 3 and a free roller 4. The active roller 2 is arranged close to the motor 1 and connected to the motor 1 through a transmission shaft. The motor 1 directly drives the active roller 2 to rotate, and the active roller 2 and the driven roller 3 are connected through a transmission chain, thereby driving the driven roller 3 to rotate during the rotation of the active roller 2. The axial center lines of the active roller 2 and the driven roller 3 are located on the same horizontal plane. The free roller 4 is fixedly arranged on the frame 10 away from one end of the motor 1 through a roller bearing seat. The rotation of the free roller 4 drives the free roller 4 to rotate through the driving force of the blank during transportation. The axial center line of the free roller 4 is higher than the axial center line of the active roller 2 and the driven roller 3.

[0027] According to an embodiment of the utility model, the guide rail 8 is detachably fixedly connected to the frame 10 at one end close to the motor 1 by means of a locking bolt 9. There are four locking bolts 9, which are symmetrically arranged on both sides of one end of the guide rail 8.

[0028] According to an embodiment of the utility model, the guide rail 8 is embedded and fixed on the cold shearing machine, and a semicircular groove 7 is provided at the upper end of the guide rail 8 for clamping the guide wheel 6. The guide rail 8 slides with the guide wheel 6 by providing a slide groove, and the semicircular groove 7 is provided at the front end of the slide groove. The guide wheel 6 is respectively provided as follows Figure 1 The front and rear sides of the frame 10 shown are both provided with two guide wheels 6, that is, two guide wheels 6 are provided on the front side of the frame 10, and two guide wheels 6 are provided on the rear side. Four slide grooves are correspondingly provided at the lower ends of the guide wheels 6, and a semicircular groove 7 is provided at the front end of each slide groove.

[0029] According to the embodiment of the utility model, when a pull-out floating roller device of the utility model is used, after the guide wheel 6 passes through the slide groove on the guide rail 8, the guide wheel 6 enters the semicircular groove 7 and is stuck, and then the frame 10 is fixed to the guide rail 8 by the bolt 9, and the floating roller device and the cold shear are fixed in position. Turn on the motor to start conveying steel, the active roller 2 along the feeding direction is connected to the motor 1 to rotate, and the driven roller 2 is driven to rotate through the chain transmission, and the free roller 4 generates a forward force to drive the free roller 4 to rotate during the transportation of the steel. When transporting the steel, the disc spring 5 lifts the active roller 2, the driven roller 3 and the free roller 4 to lift the steel and convey the steel forward. When shearing, the steel is pressed down, the disc spring 5 under the roller bearing seat 11 is compressed, the active roller 2, the driven roller 3 and the free roller 4 sink, the steel is fixed and closely contacted with the shear blade on the cold shear, and the cold shear operates the upper and lower shear blades to complete the shearing. After the last batch of steel materials is sheared, the active roller 2 drives the driven roller 3 and the free roller 4 to feed the materials forward for breaking and shearing. At this time, the remaining tail of the materials on the roller table stops breaking because the length of the materials is not enough to be transported forward. At this moment, only a small amount of shorter tail of materials will remain on the roller table, and the remaining tail of the materials will be pushed down into the chute when a new batch of materials to be sheared comes forward. At the same time, the tail of materials that are not pushed down are also pushed forward by the rotating active roller 2, the driven roller 3 and the free roller 4 in the process of continuous material transportation at the back and fall into the chute for collection.

[0030] When the floating roller device needs to be disassembled for maintenance, the closing bolt 9 can be removed, and the floating roller device as a whole can be pulled toward the closing bolt 9 under the sliding action of the guide wheel 6 to complete the disassembly of the frame 10 and the guide rail 8.

[0031] According to the embodiments of the utility model, the utility model, through the design of a pull-out floating roller device, introduces a closely spaced roller group drive, and the blade front roller group can track the change of the contact force of the pressure roller on the blank, complete the tracking of pressing down or lifting up, and match and establish the best state of ideal shearing, balance, and transportation. This technology is a necessary configuration for upgrading the practical performance of the front area equipment of new shearing machines in the future.
