Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machine tools, in particular to a work roll with box grinding full-automatic overturning and supporting system. BACKGROUND

[0002] Rollers are generally divided into backup rolls and work rolls. In the finishing mill of a hot rolling mill, the backup rolls and work rolls are generally supported in bearing boxes and then installed in the rack. After a period of rolling work, the roll surface precision is reduced, which affects the rolling quality, and the roll needs to be removed from the rack for grinding correction on a roll grinder. The replacement frequency of hot rolling work rolls is very high, reaching about one hundred times a day. If each work roll is ground without a box, two people are needed to disassemble the bearing box of each roll for about an hour, which is time-consuming and labor-intensive, not only wasting labor costs, but also reducing the service life of the bearing. The bearing box of the work roll has a moderate size and can generally be ground online with the box. However, the bearing box of the work roll generally has a special shape. If the work roll with the bearing box in a natural state is placed on a roll grinder for grinding, interference between the bearing box and the grinder wheel frame will occur during the grinding process, and the work roll bearing box needs to be overturned by a certain angle. When the bearing box is overturned by a certain angle, it is no longer in the state of gravity, and if there is no cooperation of other mechanisms to constrain the bearing box, the bearing box will shake greatly during the grinding process, which cannot guarantee the processing precision of the work roll grinding.

[0003] In the prior art, the mechanism for restraining the bearing box during overturning is to set two oil cylinders below the bearing box body, and a connecting rod holding mechanism is formed between the two oil cylinders to hold the box body. When the workpiece bearing box has a large turning radius or the side of the bearing box has no support, the bearing box will collide and interfere with the holding mechanism fixed below the position of the bearing box body due to the constraints of the specifications and center height of the machine tool itself. Therefore, how to provide a device that can effectively hold and support to avoid various interferences during the overturning of the bearing box is a problem that needs to be solved by those skilled in the art.

Figure 6At the indicated position, the first detection switch 311 for the roll-over mechanism sends a signal. Then, the roll, suspended by the lifting device, is placed on the roll surface soft landing device 2. At this point, the roll installation button is activated, and the roll surface soft landing device 2 lowers the roll through hydraulic pressure changes in the cylinder 202 until it reaches the second soft landing position detection switch 207, at which point the roll surface soft landing device 2 stops descending. The motor 301 is then started, and the roll-over mechanism 3 begins its forward roll-over action. When the third detection switch 313 for the roll-over mechanism sends a signal, the bearing housing 111 rotates 90°, and the roll-over mechanism 3 stops rotating. To avoid inertia, the motor 301 is equipped with a self-locking function. Yes; the bearing housing support 102 moves left and right by the change in oil pressure of the bearing housing support moving cylinder 103.

[0047] After grinding, the bearing housing 111 is first moved back to its original position by changing the hydraulic pressure of the bearing housing positioning cylinder 105. Then, the roller surface soft landing device 2 raises the roller by changing the hydraulic pressure of the cylinder body 202. When the roller rises to the soft landing second position detection switch 207, the roller surface soft landing device 2 stops rising. The bearing housing support 102 moves left and right by changing the hydraulic pressure of the bearing housing support moving cylinder 103.

The second soft landing position detection switch is used to detect the middle position of the auxiliary support roll surface of the roller surface soft landing device, and is used for the interlocking of the box-turning mechanism's box-turning action. The third soft landing position detection switch is used to detect the lowest position setting of the auxiliary support roll surface of the roller surface soft landing device.

2. The fully automatic turning and supporting system for work roll belt grinding according to claim 1, characterized in that: The second base drive assembly includes a cylinder seat, a bearing housing support moving cylinder, and a tie rod seat. The sliding assembly includes two heavy-duty linear guide pairs, which are mounted on the first base of the support. The cylinder seat is fixed between the two heavy-duty linear guide pairs. The bearing housing support moving cylinder is fixed on the cylinder seat. One end of the tie rod seat is connected to the second base of the support, and the other end of the tie rod seat is connected to the piston rod A of the bearing housing support moving cylinder.

3. The fully automatic turning and supporting system for work roll belt grinding according to claim 2, characterized in that: Telescopic guide rail protective covers are mounted on the first base and the second base of the support seat via brackets to protect the two heavy-duty linear guide rail pairs.

4. The fully automatic turning and supporting system for work roll belt grinding according to claim 1, characterized in that: The support detection assembly includes a bearing housing support first position detection switch and a bearing housing support second position detection switch. The bearing housing support first position detection switch is used to detect the position where the bearing housing support supports the bearing housing, and the bearing housing support second position detection switch is used to detect the position where the bearing housing support leaves the flipping area.

5. The fully automatic turning and supporting system for work roll belt grinding according to claim 1, characterized in that: The lifting assembly includes a cylinder body, a piston rod B, and a guide rod. The cylinder body is mounted on the positioning support. The piston rod B and the guide rod are both mounted inside the cylinder body. The cylinder body is used to drive the piston rod B to perform lifting and lowering movements. The guide rods are provided on both sides of the piston rod B, and the roller support is provided at the top of the piston rod B.

6. The fully automatic turning and supporting system for work roll belt grinding according to claim 1, characterized in that: The tilting drive assembly includes a motor, a gearbox, a gear shaft, and an idler wheel. The motor and the gearbox are mounted on the guide rail housing. The gearbox is connected to the gear shaft, and the gear shaft performs a two-stage gear transmission through the idler wheel and the arc-shaped tilting gear.

7. The fully automatic turning and supporting system for work roll belt grinding according to claim 1, characterized in that: The box-flipping detection component includes a first box-flipping detection switch, a second box-flipping detection switch, and a third box-flipping detection switch. The first box-flipping detection switch is used to detect the start position of the forward box-flipping action or the end position of the reverse box-flipping action of the box-flipping mechanism. The second box-flipping detection switch is used to locate the position where the motor begins to decelerate during the box-flipping action of the box-flipping mechanism. The third box-flipping detection switch is used to detect the end position of the forward box-flipping action or the start position of the reverse box-flipping action of the box-flipping mechanism.

8. The fully automatic turning and supporting system for work roll belt grinding according to claim 1, characterized in that: It also includes an arc-shaped pressure plate, an upper copper slide rail, a lower copper slide rail, and a side copper slide rail. The arc-shaped pressure plate is used to press the arc-shaped reversing gear. The upper copper slide rail, the lower copper slide rail, and the side copper slide rail are disposed between the guide rail housing and the arc-shaped reversing gear to reduce friction.
