Description

Technical Field

[0001] The utility model relates to an on-line detection device for key parameters of a roll system of a plate straightening machine, belonging to the technical field of clearance measurement in the metallurgical industry. Background Technique

[0002] The plate straightening machine is an important device on the hot-rolled medium and heavy plate production line. It straightens the rolled steel plate, which is an important process measure commonly adopted to optimize the performance of the steel plate, ensure that the flatness of the steel plate meets the standard, and improve the rolling rhythm. The roll system of the straightening machine is the core component of the straightening machine, and its operating state directly affects the stable operation of the plate straightening machine.

[0003] See the appendix Figure 6 , the roll system of the plate straightening machine usually consists of working rolls 001 and supporting rolls 002. Each working roll is supported by multiple supporting rolls in an alternating manner to prevent the working roll from flexing and deforming, which affects the quality of the straightened product. At the same time, it can effectively reduce the bearing force of the working roll shaft and avoid damage to the working roll bearing. Key parameters such as the roll surface wear of the working roll and the supporting roll, the clearance between the working roll and the supporting roll, and the operating state of the supporting roll directly affect the service life of the roll system of the straightening machine.

[0004] The above key parameters are usually detected during the assembly process of the roll system. After the assembly is completed and after the machine is put into operation, due to space limitations, it is impossible to measure and detect. If the wear of some roll surfaces exceeds the standard and the clearance increases, the number of effective supporting rolls will be reduced, resulting in uneven force on the supporting rolls, affecting the service life of the bearings and causing bearing damage. At the same time, due to the existence of assembly clearance, by turning the working roll by barring the gears, it is impossible to confirm the reason why the corresponding supporting roll does not rotate. If the bearing is damaged and the supporting roll is jammed, and the jammed supporting roll cannot be detected in time, it will cause the jammed supporting roll to contact and rub against the working roll, resulting in sticking steel on the surface of the working roll and causing indentations on the surface of the straightened steel plate, affecting the product quality. Content of the Utility Model

[0005] The purpose of the utility model is to provide an on-line detection device for key parameters of a roll system of a plate straightening machine, which can conveniently and quickly measure the clearance between the working roll and the supporting roll of the straightening machine, and can also quickly check the operating state of the supporting roll, and solve the problems existing in the background technique.

[0006] The technical solution of the utility model is:

[0007] An on-line detection device for key parameters of a roll system of a plate straightening machine includes a guide plate, a through hole, a handle and a feeler gauge. The guide plate is an arc-shaped plate that matches the working roll of the straightening machine. A handle is provided on the guide plate. A through hole that matches the feeler gauge is provided in the length direction of the guide plate. One end of the guide plate is the entrance for the feeler gauge to pass through, and the other end of the guide plate is the exit for the feeler gauge to pass through. The thickness of the feeler gauge matches the clearance between the working roll and the supporting roll of the straightening machine.

[0008] A feeler gauge positioning mechanism matched with a feeler gauge is arranged on the guide plate.

[0009] The feeler gauge positioning mechanism includes a pressing plate, a nut and a screw rod. The nut is fixed on the guide plate, the screw rod is in threaded connection with the nut, one end of the screw rod is fixedly connected with the pressing plate, and the pressing plate presses on the feeler gauge.

[0010] A chamfer is arranged at one end of the through outlet of the guide plate.

[0011] The length of the feeler gauge is greater than the length of the guide plate.

[0012] The feeler gauge includes a gauge head and a gauge body. The gauge head and the gauge body are connected together by a rivet, and the gauge head passes through the through outlet of the guide plate.

[0013] When the utility model is adopted, during use, the guide plate is attached to the working roll of the straightening machine, so that the through outlet of the guide plate is located at the joint of the working roll and the supporting roll of the straightening machine. Then, the feeler gauge is passed through the through hole of the guide plate and enters the joint of the working roll and the supporting roll of the straightening machine. The gap between the working roll and the supporting roll of the straightening machine can be measured by using the feeler gauge. At the same time, the straightening machine is started. If the feeler gauge cannot be bitten in and rotated with the roll, or its surface is squeezed and damaged due to the rotation of the working roll after being bitten in, it indicates that the supporting roll has jamming and needs to be repaired.

[0014] The beneficial effects of the utility model are as follows: the gap between the working roll and the supporting roll of the straightening machine can be measured conveniently and quickly, and the running state of the supporting roll can also be checked quickly.

[0023] The following further illustrates the present utility model through examples in conjunction with the accompanying drawings.

[0024] Refer to the attached Figures 1-5 , An on - line detection device for key parameters of the roll system of a sheet straightening machine, comprising a guide plate 1, a through hole 2, a handle 5 and a feeler gauge 9. The guide plate 1 is an arc - shaped plate that matches the working roll of the straightening machine. A handle 5 is provided on the guide plate 1. A through hole 2 that matches the feeler gauge 9 is provided in the length direction of the guide plate 1. One end of the guide plate 1 is the entrance for the feeler gauge 9 to pass through, and the other end of the guide plate 1 is the exit for the feeler gauge 9 to pass through. The thickness of the feeler gauge 9 matches the gap between the working roll and the support roll of the straightening machine.

[0025] In this embodiment, refer to the attached Figures 1-5 , The guide plate 1 is an arc - shaped plate, and its radian is coupled with the surface curvature of the working roll of the straightening machine, and can be attached to the working roll of the straightening machine.

[0026] Refer to the attached Figure 1 , 2 , A through hole 2 that matches the feeler gauge 9 is provided in the length direction of the guide plate 1. One end of the guide plate 1 is the entrance for the feeler gauge 9 to pass through, and the other end of the guide plate 1 is the exit for the feeler gauge 9 to pass through. A chamfer 3 is provided at the exit end of the guide plate 1, and the chamfer 3 facilitates the entry of the guide plate 1 into the connection between the working roll and the support roll of the straightening machine.

[0027] Refer to the attached Figure 1 , 2 , A notch 4 that communicates with the through hole 2 is also provided on the guide plate 1. A nut 7 is fixedly installed in the notch 4. A lead screw 8 is threadedly connected to the nut 7. The end of the lead screw 8 is connected to the pressure plate 6. By rotating the lead screw 8, the position of the pressure plate 6 can be adjusted, and the feeler gauge 9 in the through hole 2 is pressed by the pressure plate 6 to prevent the feeler gauge from moving in the through hole 2.

[0028] Refer to the attached Figure 3 , 4 , The feeler gauge 9 comprises a feeler head 10 and a feeler body 11. The feeler head 10 and the feeler body 11 are connected together by a rivet 12. The feeler head 10 passes through the exit of the guide plate 1. The length of the feeler gauge 9 is greater than the length of the guide plate 1. The thickness of the feeler head 10 matches the gap between the working roll and the support roll of the straightening machine. In this way, when the feeler head 10 is damaged, only the feeler head 10 needs to be replaced, rather than the whole feeler gauge, and the maintenance cost is lower.

[0029] Refer to the attached Figure 5 , The usage method of this device is as follows:

[0030] When in use, first hold the handle 5 by hand, attach the guide plate 1 to the working roll 001 of the straightening machine, so that the outlet of the guide plate 1 is located at the connection of the working roll 001 and the supporting roll 002 of the straightening machine. Then insert the feeler gauge 9 into the inlet of the guide plate 1 until it passes through the guide plate 1 and enters the connection of the working roll 001 and the supporting roll 002 of the straightening machine. The feeler gauge 9 can be used to measure the gap between the working roll and the supporting roll of the straightening machine. At the same time, start the straightening machine. If the feeler gauge 9 cannot be bitten in and rotated with the roll, or its surface is squeezed due to the rotation of the working roll after being bitten in, it indicates that the supporting roll has jamming and needs to be repaired.
