[0052] The finishing mill is responsible for rolling the semi-finished products into finished metal rods. The existing non-ferrous metal rolling mill equipment consists of multiple rolling mills arranged horizontally and vertically to achieve twist-free rolling. The roll gap adjustment needs to be adjusted manually. However, the roll gap of the finished product rack needs to be adjusted frequently during production, which makes the roll gap adjustment very cumbersome and increases the workload of production staff.

[0053] Based on this, the present invention provides a rolling mill group, which can normally transmit the power output by the driving mechanism to the eccentric sleeve adjustment mechanism through the universal joint coupling, thereby ensuring the normal operation of the eccentric sleeve adjustment mechanism, and further realizing the automatic adjustment of the roll gap by adding a driving mechanism to the workstation.

[0054] Example 1

[0055] The specific embodiments of the present invention are described in detail below in conjunction with the roll gap adjustment device of the first aspect of the present invention.

[0056] It should be noted that the roller gap adjustment device of the first aspect of the present invention is only a preferred embodiment of the present invention. The roller gap adjustment device of the present invention can adopt the roller gap adjustment device of the first aspect of the present invention or other structures. For the convenience of explanation, the roller gap adjustment device of the first aspect of the present invention will be explained below.

[0057] Combination Figures 1 to 5 As shown, this embodiment discloses a roller gap adjustment device, including an eccentric sleeve assembly 6, an eccentric sleeve adjustment mechanism and a driving mechanism.

[0058] The eccentric sleeve assembly 6 is gap-assembled to the box body 13 and the panel 14. An eccentric sleeve assembly inner hole is provided on the eccentric sleeve assembly 6. The eccentric sleeve assembly inner hole is suitable for concentrically assembling the adjustable roller shaft 8. The outer circle center of the eccentric sleeve assembly 6 is not concentric with the center of the eccentric sleeve assembly inner hole, that is, there is a distance between the center line of the outer circle of the eccentric sleeve assembly and the center line of the inner hole of the eccentric sleeve assembly, and the distance is the eccentric distance of the eccentric sleeve.

[0059] The eccentric sleeve adjusting mechanism is connected to the eccentric sleeve assembly 6 , and the eccentric sleeve adjusting mechanism is suitable for adjusting the position of the inner hole of the eccentric sleeve assembly so as to make the adjustable roller shaft 8 move closer to or away from the input roller shaft 9 .

[0060] The output shaft end of the driving mechanism is connected to the input shaft end of the eccentric sleeve adjusting mechanism through a universal joint coupling 2.

[0061] In the above-mentioned roll gap adjustment device, when the eccentric sleeve assembly 6 is adjusted, even if the axis of the input shaft end of the eccentric sleeve adjustment mechanism is deflected, the input shaft of the eccentric sleeve adjustment mechanism that is not on the same axis as the output shaft of the driving mechanism is continuously rotated through the universal joint coupling 2, and the power output by the driving mechanism can be normally transmitted to the eccentric sleeve adjustment mechanism, ensuring the normal operation of the eccentric sleeve adjustment mechanism, and then the drive mechanism can be added to the workstation to automatically adjust the roll gap. Compared with the current manual roll gap adjustment method, this embodiment can use the drive mechanism to automatically adjust the roll gap, thereby greatly reducing the workload of production staff and improving the speed and efficiency of roll gap adjustment.

[0062] In some embodiments, the eccentric sleeve assembly 6 includes a first eccentric sleeve 61, a second eccentric sleeve 62 and a connecting member 63. The first eccentric sleeve 61 is mounted on the panel 14. The second eccentric sleeve 62 is mounted on the box body 13. There is a spacing between the first eccentric sleeve 61 and the second eccentric sleeve 62, and a space suitable for accommodating the adjustable roller shaft engagement portion is formed therebetween. The connecting member 63 is connected between the first eccentric sleeve 61 and the second eccentric sleeve 62 to connect the first eccentric sleeve 61 and the second eccentric sleeve 62 into one body.

[0063] The connecting member 63 includes a connecting plate 631 and two positioning plates 632, and the connecting member 63 is perpendicular to the positioning plates 632. The connecting plate 631 is connected between the side wall of the first eccentric sleeve 61 and the side wall of the second eccentric sleeve 62, and the two positioning plates 632 are spaced apart and are basically arranged on the connecting plate 631.

[0064] More specifically, the connecting member 63 is detachably connected to the first eccentric sleeve 61 and the second eccentric sleeve 62. Positioning parts are provided on the side walls of the first eccentric sleeve 61 and the second eccentric sleeve 62, and positioning grooves are provided on the positioning parts. The positioning grooves are adapted to the connecting plate 631. The positioning grooves and the connecting plate 631 are respectively provided with threaded holes, and the connecting plate 631 can be positioned on the positioning grooves by screws.

[0065] In some embodiments, the eccentric sleeve adjustment mechanism includes a nut pin 5, an adjusting screw 4 and a spherical roller bearing 7. The nut pin 5 is rotatably set on two positioning plates 632, and the axis of the nut pin 5 is parallel to the axis of the adjustable roller shaft 8. The adjusting screw 4 is threadedly mounted on the nut pin 5, and the axis of the adjusting screw 4 is perpendicular to the axis of the nut pin 5. The adjusting screw 4 is rotatably set on the spherical roller bearing 7 and the adjusting screw 4 extends from the spherical roller bearing 7. In this embodiment, when the adjusting screw 4 rotates, the adjusting screw 4 will drive the nut pin 5 to move, because the nut pin 5 is rotatably set on the two positioning plates 632, thereby causing the nut pin 5 to rotate, thereby driving the eccentric sleeve assembly 6 connected to the nut pin 5 to rotate around its outer circle center.

[0066] In some embodiments, the universal joint coupling 2 is connected to the input shaft end of the adjusting screw 4 .

[0067] In some embodiments, the driving mechanism is a servo motor system. The servo motor system includes a servo motor 1 and a servo motor driver 3. The controlled end of the servo motor 1 is connected to the output end of the servo motor driver 3. The controlled end of the servo motor driver 3 is connected to the output end of the PLC controller. That is, the PLC programmable logic controller controls the action of the servo motor 1 through the servo motor driver 3, and then the universal joint coupling 2 transmits the action to the adjustment screw 4 to achieve automatic adjustment of the roller gap.

[0068] In some embodiments, a limit block 41 is detachably provided at one end of the adjusting screw rod 4 that is not connected to the driving mechanism to prevent the adjusting screw rod 4 from slipping off the nut pin shaft 5 .

[0069] In the above-mentioned roller gap adjustment device, since the distance between the nut pin shaft 5 and the outer circle axis of the eccentric sleeve assembly 6 remains unchanged, the axis of the screw rod 4 will also deflect by 3~4° in the process of adjusting the maximum roller gap to the minimum roller gap, which is achieved by the spherical roller bearing 7. Therefore, conventional couplings with high coaxiality requirements are not suitable for application in this scenario, which is also the reason why automatic adjustment of the roller gap has not been achieved on this workstation (adding a servo motor). In view of the non-fixedness of the axis of the adjustment screw rod 4, the present invention uses a universal joint coupling 2, and utilizes the universal joint coupling 2 to normally transmit the power of the servo motor to the adjustment screw rod, which can adapt to low speed, low load, and poor coaxiality conditions. The eccentric sleeve assembly 6 has a certain rotation range, within which the maximum roller gap and the minimum roller gap can be obtained, and the size of the roller gap can be adjusted as needed.

[0070] Example 2

[0071] The specific embodiments of the present invention are described in detail below in conjunction with the intelligent workstation according to the second aspect of the present invention.

[0072] It should be noted that the intelligent workstation of the second aspect of the present invention is only a preferred embodiment of the present invention. The intelligent workstation of the present invention can adopt the intelligent workstation of the second aspect of the present invention or other structures. For the convenience of explanation, the intelligent workstation of the second aspect of the present invention is used for explanation below.

[0073] Combination Figures 1 to 8 As shown, this embodiment discloses an intelligent workstation, including a box 13, a panel 14, an input roller shaft 9, an adjustable roller shaft 8, a shell and a roll gap adjustment device. The panel 14 is connected to the box 13 by a connecting plate, and the two form a cavity after being connected. The input roller shaft 9 is rotatably arranged on the panel 14 and the box 13 respectively through a concentric bearing sleeve assembly 10. The adjustable roller shaft 8 and the input roller shaft 9 are driven by cylindrical gear meshing, and the axes of the two are parallel to each other, and the adjustable roller shaft 8 unilaterally moves closer to or away from the input roller shaft 9. The roll gap adjustment device is suitable for adjusting the position of the adjustable roller shaft 8. The shell covers the outside of the cavity formed by the box 13 and the panel 14.

[0074] The housing 13 is provided with a first inner hole 131 and a second inner hole 132 . The first inner hole 131 cooperates with the eccentric sleeve assembly 6 , and the second inner hole 132 cooperates with the concentric bearing sleeve assembly 10 .

[0075] The panel 14 is provided with a third inner hole 141 and a fourth inner hole 142 . The third inner hole 141 cooperates with the eccentric sleeve assembly 6 , and the fourth inner hole 142 cooperates with the concentric bearing sleeve assembly 10 .

[0076] The specific principle of the roll gap adjustment device for adjusting the roll gap is as follows:

[0077] The input roller shaft 9 is installed in the inner hole of the concentric bearing sleeve assembly 10, and the concentric bearing sleeve assembly 10 is installed in the second inner hole 132 of the housing and the fourth inner hole 142 of the panel. The axis of the input roller shaft 9 does not change. The outer circle of the concentric bearing sleeve assembly 10 is concentric with the second inner hole 132 and the fourth inner hole 142, respectively, and the inner hole of the concentric bearing sleeve assembly 10 is also concentric with the second inner hole 132 and the fourth inner hole 142, respectively, so the position of the input roller shaft 9 cannot be adjusted. The concentric bearing sleeve assembly 10 is also provided with a stop pin 15, which prevents the concentric bearing sleeve assembly 10 from rotating radially.

[0078] The adjustable roller shaft 8 is installed in the inner hole of the eccentric sleeve assembly, and the eccentric sleeve assembly 6 is installed in the first inner hole 131 of the box body and the third inner hole 141 of the panel.

[0079] When it is necessary to adjust the roll gap between the adjustable roll shaft 8 and the input roll shaft 9, an operation command is sent to the servo motor 1 through the servo motor driver 3, and the servo motor 1 runs. The servo motor 1 transmits the torque to the adjusting screw 4 through the universal joint coupling 2, driving the adjusting screw 4 in the eccentric sleeve adjustment mechanism to rotate, so that the relative position of the nut pin shaft 5 changes, and the nut pin shaft 5 and the eccentric sleeve assembly 6 are hinged, so that the eccentric sleeve assembly 6 is radially deflected with its outer circle axis as the center.

[0080] When the eccentric sleeve assembly 6 deflects radially in the inner holes (the first inner hole 131 and the third inner hole 141) of the box body and the panel, the eccentric sleeve assembly 6 rotates with the outer circle center of the eccentric sleeve assembly, and the position of the axis of the inner hole of the eccentric sleeve assembly changes, and the axis of the adjustable roller shaft 8 installed in the inner hole of the eccentric sleeve assembly changes, so that the axis distance between the adjustable roller shaft 8 and the input roller shaft 9 changes, and the roller gap is adjusted. When the eccentric sleeve assembly 6 rotates counterclockwise by a certain angle, the roller gap between the adjustable roller shaft 8 and the input roller shaft 9 increases; when the eccentric sleeve assembly 6 rotates clockwise by a certain angle, the roller gap between the adjustable roller shaft 8 and the input roller shaft 9 decreases.

[0081] Existing workstations lack the ability to self-perceive status, which makes it difficult for staff to promptly discover equipment failures and perform repairs, resulting in equipment damage or even greater losses.

[0082] In order to solve the problem that the workstation lacks the ability to self-perceive the state, in some embodiments, a temperature detection unit is provided on the eccentric sleeve assembly 6 and / or the concentric bearing sleeve assembly 10. The temperature detection unit includes at least one thermocouple 12. More specifically, in combination with Figure 6 and Figure 8 As shown, thermocouples 12 are added to the sliding bearings on the load-bearing side and the drive side of the workstation. The thermocouple 12 can monitor the temperature of the sliding bearing in real time and feed back the detected temperature information to the PLC programmable logic controller. When the temperature value is higher than the alarm value set inside the PLC programmable logic controller, the staff is reminded to check the equipment in time; when the temperature value is higher than the dangerous value set inside the PLC programmable logic controller, the machine is shut down and the waste cutting process is started to avoid equipment burning or causing greater losses.

[0083] The installation process of the thermocouple 12 is as follows: pre-processing holes and installation threads for installing the thermocouple probe on the eccentric sleeve assembly 6 and / or the concentric bearing sleeve assembly 10, and fastening the thermocouple 12 to the eccentric sleeve assembly 6 and / or the concentric bearing sleeve assembly 10 with screws.

[0084] In order to solve the problem that the workstation lacks the ability to self-perceive the state, in some embodiments, combined with Figure 7As shown, at least one vibration sensor 11 is provided on the box 13. The vibration sensor 11 can monitor the vibration of the workstation in real time and feed back the detected vibration information to the PLC programmable logic controller. When the vibration information value is higher than the alarm value set inside the PLC programmable logic controller, the staff is reminded to check the equipment in time; when the vibration information value is higher than the dangerous value set inside the PLC programmable logic controller, the machine is shut down and the waste cutting process is started to avoid equipment burning or causing greater losses.

[0085] The installation process of the vibration sensor 11 is as follows: In order to adapt to the complex working conditions of the production site, the vibration sensor 11 is fastened to the workstation box by screw connection. Threaded holes are pre-processed at the vibration monitoring position on the workstation box in advance, and the vibration sensor 11 is fastened to the workstation box with screws.

[0087] The specific embodiments of the present invention are described in detail below in conjunction with the rolling mill group according to the third aspect of the present invention.

[0088] It should be noted that the rolling mill group of the third aspect of the present invention is only a preferred embodiment of the present invention. The rolling mill group of the present invention can adopt the rolling mill group of the third aspect of the present invention or other structures. For the convenience of explanation, the rolling mill group of the third aspect of the present invention will be explained below.

[0089] This embodiment discloses a rolling mill group, including multiple groups of intelligent workstations, and two adjacent groups of intelligent workstations are arranged alternately in parallel and vertically.

[0090] As a preferred embodiment, only the last finished rolling mill (workstation) is equipped with a servo motor to automatically adjust the roll gap. As an alternative embodiment, each finishing mill (workstation) can be equipped with a servo motor to automatically adjust the roll gap.
