Description

Technical Field

[0001] This utility model relates to the technical field of testing devices, and in particular to a hot continuous rolling mill roll wear resistance testing device. Background Technology

[0002] Hot continuous rolling is one of the important processing technologies in steel production. It processes steel billets into the required plates or strips through continuous rolling. The wear of the rolls mainly comes from the following aspects: first, frictional wear with the high-temperature steel billet; second, thermal fatigue and mechanical fatigue generated during the rolling process; and third, oxidation and corrosion in the rolling environment. These factors together lead to the gradual wear of the roll surface, affecting rolling accuracy and product quality.

[0003] However, testing the wear resistance of rolling mill rolls has always been a technical challenge. Traditional testing methods typically involve actual rolling tests, where the rolls are directly used on the production line, and their performance is evaluated by measuring the amount of wear. While this method is intuitive, it is costly and time-consuming, making it difficult to meet the needs of rapid research and development and optimization. Utility Model Content

[0037] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0038] This utility model relates to a wear resistance testing device for hot continuous rolling mill rolls, such as... Figures 1 to 5 As shown, it includes:

[0039] Mounting base 1 is independently and fixedly set to support the entire testing device. The roll is rotatably mounted on mounting base 1.

[0040] Mounting bracket 2 is slidably disposed within the through hole of mounting base 1;

[0041] The lead screw 3 is rotatably mounted on the mounting bracket 2, and the rotation axis of the lead screw 3 is parallel to the rotation axis of the roll. The lead screw 3 is coaxially mounted on the output end of the servo motor 4, and the servo motor 4 is mounted on the mounting bracket 2.

[0042] The movable frame 5 is fitted onto the lead screw 3 and is slidably installed along the length of the lead screw 3;

[0043] Mounting column 6 is rotatably mounted in the shaft hole of movable frame 5, and the rotation axis of mounting column 6 is parallel to the rotation axis of lead screw 3;

[0044] The test wheel 7 is coaxially mounted on the mounting column 6. The test wheel 7 is used to simulate the working environment of the roll and to conduct wear resistance tests through contact with the roll.

[0045] The drive mechanism 8 is mounted on the mounting bracket 2 and is used to provide rotational power to the test wheel 7.

[0046] The lifting mechanism 9 is installed inside the cavity of the mounting base 1. The lifting mechanism 9 is used to adjust the working height of the test wheel 7 driven by the mounting frame 2. It can adapt to rolls of different diameters and change the contact pressure between the test wheel 7 and the roll, thereby simulating different working conditions.

[0047] The working principle of this device is as follows:

[0048] First, the working height of the mounting frame 2 is adjusted by the lifting mechanism 9 so that the test wheel 7 contacts the roll. The servo motor 4 drives the lead screw 3 to rotate, which drives the moving frame 5 to slide along the length of the lead screw 3, thereby adjusting the position of the test wheel 7. The drive mechanism 8 drives the test wheel 7 to rotate, simulating the working state of the roll. By adjusting the contact pressure and relative movement speed between the test wheel 7 and the roll, the wear resistance of the roll under different working conditions can be tested.

[0049] The independently fixed mounting base 1 provides stable support for the entire testing device, ensuring the stability and safety of the testing process. It also facilitates the rotation and installation of the roll, ensuring its normal operation. The mounting frame 2 can slide within the through hole of the mounting base 1, providing a basis for adjusting the position of the test wheel 7. In conjunction with the lead screw 3, servo motor 4, and moving frame 5, the servo motor 4 drives the lead screw 3 to rotate, precisely driving the moving frame 5 to slide along the length of the lead screw 3, achieving precise adjustment of the test wheel 7's position. This facilitates the simulation of different working states of the roll. The mounting column 6 is rotatably mounted within the shaft hole of the moving frame 5, allowing the test wheel 7 to rotate flexibly and better contact the roll to simulate the working environment. The test wheel 7 is coaxially mounted. The test roller 7, mounted on the mounting column 6, directly undertakes the key task of simulating the working environment of the roll and conducting wear resistance tests. The drive mechanism 8, mounted on the mounting frame 2, provides stable rotational power to the test roller 7, enabling it to continuously simulate the rotational state of the roll during operation. The lifting mechanism 9, mounted in the cavity of the mounting base 1, is particularly crucial. It can flexibly adjust the working height of the test roller 7 driven by the mounting frame 2 to adapt to rolls of different diameters and broaden the scope of testing applications. It can also adjust the contact pressure between the test roller 7 and the roll by changing the height, comprehensively simulating diverse working conditions. This greatly improves the comprehensiveness, accuracy, and reliability of the test, providing a strong guarantee for the accurate testing of the wear resistance performance of hot rolling mill rolls.

[0050] As a preferred option, such as Figures 1 to 5 As shown, the drive mechanism 8 includes:

[0051] The drive shaft 81 is rotatably mounted on the mounting bracket 2, and the rotation axis of the drive shaft 81 is parallel to the rotation axis of the mounting column 6;

[0052] Hollow shaft 82 is rotatably mounted on mounting bracket 2, and drive shaft 81 is disposed inside the shaft cavity of hollow shaft 82. Hollow shaft 82 rotates synchronously with drive shaft 81, and hollow shaft 82 is slidably disposed along the length direction of drive shaft 81.

[0053] The transmission mechanism 83 is connected to the hollow shaft 82 and the mounting column 6 respectively. The transmission mechanism 83 is used to drive the mounting column 6 to rotate synchronously.

[0054] The power motor 84 is mounted on the mounting bracket 2, and one end of the drive shaft 81 is mounted on the output end of the power motor 84;

[0055] The drive shaft 81, which is rotatably mounted on the mounting frame 2 and whose rotation axis is parallel to the mounting column 6, rotates stably under the drive of the power motor 84, providing the power foundation for the entire driving process. The hollow shaft 82 is sleeved on the outside of the drive shaft 81, which can rotate synchronously with the drive shaft and slide along its length. This unique structural design allows the drive mechanism 8 to not only meet the requirements of rotation transmission but also adapt to the adjustment of the position of the test wheel 7, ensuring that the power transmission is not affected when the moving frame 5 drives the test wheel 7 to change position. The transmission mechanism 83 connects the hollow shaft 82 and the mounting column 6 respectively, and can smoothly and efficiently transmit the rotation of the hollow shaft 82 to the mounting column 6, thereby driving the test wheel 7 to rotate synchronously, ensuring that the test wheel 7 can accurately simulate the rotation state of the roll during operation.

[0056] As a preferred option, such as Figures 1 to 5 As shown, the transmission mechanism 83 includes:

[0057] The drive pulley 83a is coaxially mounted on the hollow shaft 82;

[0058] Driven pulley 83b is coaxially mounted on mounting post 6;

[0059] The transmission belt 83c is rolled and installed in conjunction with the driving pulley 83a and the driven pulley 83b respectively.

[0060] The movable frame 5 is equipped with an isolator 83d, and the transmission belt 83c is located inside the isolator 83d;

[0061] The driving pulley 83a is coaxially mounted on the hollow shaft 82, and the driven pulley 83b is coaxially mounted on the mounting column 6. The transmission belt 83c is rolled together with the two, which can smoothly and efficiently transmit the rotational power of the hollow shaft 82 to the mounting column 6, thereby driving the test wheel 7 to rotate synchronously. This ensures that the test wheel 7 accurately simulates the rotational state of the rolling mill. At the same time, this belt drive method has the characteristics of buffering and absorbing vibration, which can effectively reduce vibration and impact during the transmission process. The isolation piece 83d set on the moving frame 5 wraps the transmission belt 83c inside, which can prevent external dust, debris and other objects from entering the mating area between the transmission belt and the pulley.

[0062] As a preferred option, such as Figures 1 to 3 As shown, the lifting mechanism 9 includes:

[0063] A drive motor 91 is installed in the inner cavity of the mounting base 1. A threaded post 92 is coaxially mounted on the output end of the drive motor 91, and the other end of the threaded post 92 is rotatably mounted on the mounting base 1.

[0064] The transmission component 93 is installed in the fixing hole of the mounting bracket 2, and the threaded inner hole of the transmission component 93 is fitted with the threaded post 92.

[0065] The drive motor 91, installed in the inner cavity of the mounting base 1, provides stable and controllable power output. The threaded column 92, coaxially mounted at its output end, rotates with the drive motor 91 when it is running. The transmission component 93 is installed in the fixing hole of the mounting bracket 2, and the threaded inner hole is tightly fitted with the threaded column 92. When the threaded column 92 rotates, the transmission component 93 will drive the mounting bracket 2 to move stably up and down along the axial direction of the threaded column 92 due to the interaction of the threads.

[0066] As a preferred option, such as Figures 1 to 4 As shown, the servo motor 4 is a bidirectional reciprocating motor. The reciprocating rotation of the servo motor 4 causes the working position of the moving frame 5 to swing back and forth.

[0067] The reciprocating rotation of the servo motor 4 drives the working position of the moving frame 5 to swing back and forth, thereby causing the position of the test wheel 7 to change back and forth as well. This design enables the test wheel 7 to cover the entire test range of the roll.

[0068] As a preferred option, such as Figures 1 to 4 As shown, a baffle 10 is provided on the movable frame 5, and the test wheel 7 is located inside the baffle 10;

[0069] The baffle 10 provides a certain degree of protection for the test wheel 7, improves the safety of the test wheel 7 during operation, and at the same time blocks and guides the debris generated by friction.

[0070] As a preferred option, such as Figures 1 to 5 As shown, the mounting post 6 and the test wheel 7 are fixed together by nuts 11;

[0071] The nut 11 fixing method is simple to operate and can quickly and effectively install the test wheel 7 firmly on the mounting column 6, ensuring that the connection between the two is tight and stable. During the test, it will not loosen or shift due to vibration, rotation or other factors. The nut 11 connection is a detachable connection. When the test wheel 7 is worn and needs to be replaced, or when the test wheel 7 needs to be maintained or repaired, it can be easily and quickly disassembled and installed, reducing maintenance costs and time costs, and improving the efficiency and flexibility of the testing device.

[0072] The wear resistance testing device for hot rolling mill rolls of this utility model can be installed, connected or set in a common mechanical manner, and can be implemented as long as it can achieve its beneficial effect.

[0073] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
