Description

Technical Field

[0001] The invention belongs to the technical field of mechanical equipment, and more specifically, relates to a rubber roller simulation testing machine and a testing method thereof. Background Art

[0002] As the quality of steel mills improves, the quality requirements for rubber rollers are also increasing simultaneously. The service life of squeeze-out rollers has been adjusted from 2-3 months to 4 to 5 months or even 6 months. During the service life, the rubber rollers are not allowed to jump or even debond, which will affect the quality of the steel belt and the production efficiency of the steel mill. Therefore, the quality of the rubber and the quality of the rubber rollers (bonding between the roller core and the rubber) are very important.

[0003] In view of the above problems, the prior art discloses a corresponding simulation test machine to simulate the working state of the rubber roller, such as patent application No. 2015103076632, application date June 8, 2015, the invention is named a rubber roller simulation test machine, the device includes a frame, the middle plate of the frame is provided with a freely rotating steel roller, the steel roller is driven by a motor on the bottom plate of the frame, a guide rail is provided between the top plate and the middle plate, a lifting device is provided on the guide rail, the lifting device is driven by a hydraulic cylinder on the top plate, the rubber roller is installed on the lifting device and can rotate freely, the lifting device can be moved up and down by the hydraulic cylinder, and the rubber roller is driven to rotate by the rotation of the steel roller after the rubber roller surface contacts the steel roller surface. The test machine has a reasonable structure and is easy to operate, and can accurately simulate the actual working conditions of the rubber roller, and provide targeted guidance for the improvement of the rubber layer formula.

[0004] However, after careful analysis, it is found that the technical solution disclosed in the patent has obvious limitations, mainly in the following aspects:

[0005] (1) The technical solution of the patent can only reflect the test completed by the rubber roller without medium. However, a considerable number of rubber rollers in steel mills operate in solution media such as alkali and acid. The presence or absence of medium has a great impact on the performance of the rubber layer of the rubber roller;

[0006] (2) The technical solution of the patent only reflects the completion test of the squeeze roller. The rubber rollers in steel mills include squeeze rollers, support rollers, steering rollers, pressure rollers and sinking rollers according to different workstations. They also include stainless steel lines, tinning lines, pickling lines and continuous annealing lines according to different production lines. They also include medium-high rollers, grooved rollers and flat rollers according to different rubber roller structures. The requirements for the performance of the rubber layer are different. The patent only reflects the direct squeeze test of the rubber roller, and cannot reflect the friction, squeeze, impact resistance and other performance of the steel belt when conveying.

[0007] (3) The technical solution of this patent uses an electric motor to transmit the test power to the rubber roller through a belt, which is only suitable for low-speed tests. During long-term high-speed tests, the stability and uniformity of the power transmission cannot be maintained, affecting the test data.

[0008] Therefore, although the technical solution of this patent discloses a rubber roller simulation testing machine, which can simulate the working state of the rubber roller under a certain working environment and medium, it cannot fully reflect the performance of the rubber roller under various production lines, workstations and environments, which is not conducive to fully testing the reliability of the rubber roller bonding and rubber layer performance, and restricts the diversified development of rubber rollers and the technological progress of rubber roller rubber materials.

[0009] In summary, how to overcome the shortcoming that the existing rubber roller simulation testing machine cannot fully simulate the working environment of the rubber roller, resulting in its low reliability, is a technical problem that urgently needs to be solved in the prior art. Summary of the invention

[0010] 1. Technical problem to be solved by the invention

[0012] The present invention also provides a rubber roller simulation testing machine testing method, which systematically guides the rubber roller rubber material design, research and development, and production process to achieve an optimal combination by establishing test data of different types of rubber rollers in different production lines and workstations, thereby effectively improving material performance and rubber layer reliability.

[0044] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and the invention.

[0045] Existing rubber roller simulation testing machines usually use two upper and lower steel bars to grind a steel belt, which can only measure the performance of the rubber roller under certain conditions. It cannot fully reflect the performance of the rubber roller under various production lines, workstations and environments, and is not conducive to fully testing the reliability of the rubber roller bonding and rubber layer performance.

[0046] In the present invention, a group of winding rollers 1 and unwinding rollers 2 for adjusting the angle are arranged on both sides of the upper and lower grinding rollers, and the roller body is driven to rise and fall by the lifting mechanism 6 to control the friction angle between the steel belt 5 and the upper and lower roller bodies. The working state of the rubber roller under different conditions can be fully simulated, and its performance can be measured. For example, the direction and magnitude of the shear stress during the friction of the rubber roller can be controlled by adjusting the angle, and the magnitude of the normal stress on the rubber roller during the friction can be controlled by adjusting the extrusion of the upper and lower roller bodies, and so on.

[0047] Specifically, combined Figure 1 A rubber roller simulation testing machine of the present invention comprises a frame body, on which a roller body and a steel belt 5 are arranged, the roller body comprises a lower roller 3 and an upper roller 4 which are arranged opposite to each other up and down, a winding roller 1 and an unwinding roller 2 are arranged on both sides of the lower roller 3, and the steel belt 5 is sleeved on the winding roller 1, the unwinding roller 2 and the lower roller 3; the lower roller 3 and the upper roller 4 are used for grinding the steel belt 5, the winding roller 1 and the unwinding roller 2 are used for adjusting the grinding angle of the lower roller 3 and the upper roller 4 to the steel belt 5, the winding roller 1, the unwinding roller 2 and the upper roller 4 are installed on a travel guide rail 7 and driven to rise and fall by a lifting mechanism 6.

[0048] The rubber roller simulation testing machine of the present invention is equipped with a winding roller 1, an unwinding roller 2, a lower roller 3 and an upper roller 4 that cooperate with each other to simulate the friction, stress and strain operations generated when the rubber rollers of the steel plant production line convey steel belts, so as to reasonably predict and evaluate the wear resistance, extrusion deformation performance and bonding performance of the rubber layer of the rubber roller during normal friction, and the wear resistance, shear tearing performance and bonding performance of the material during abnormal friction.

[0049] Specifically in this embodiment, the lower roller 3 is driven to rotate by a variable frequency motor 9, and a liquid injection container 8 and a solution recovery device 10 are also provided on the frame body. When the lower roller 3 and the upper roller 4 grind the steel belt 5, the liquid injection container 8 is used to drip the grinding roller body. The high-performance variable frequency motor can be used to simulate the production operation of rubber rollers on different production lines with variable or fixed speed, and the rubber layer's anti-extrusion deformation performance, wear resistance and bonding performance are tested; the power transmission is stable, and it can effectively reduce energy loss and noise compared to rubber belt transmission.

[0050] Preferably, in order to accurately control the solution dripping speed, the liquid injection container 8 in the present invention is an automatic metering control system. By setting up an automatic metering dripping system, the friction and extrusion performance of the rubber roller in a wet and dry environment can be simulated. In addition, the rated speed of the variable frequency motor 9 in the present invention is 50-1000r / min, and the speed can be reasonably set according to needs.

[0051] As an embodiment, in a rubber roller simulation test machine of the present invention, the winding roller 1 and the unwinding roller 2 are rubber rollers, and the lower roller 3 and the upper roller 4 are steel rollers or rubber rollers. Further, when the lower roller 3 and the upper roller 4 are steel rollers, the steel rollers are heated and temperature controlled by an electric field or a magnetic field, and the temperature of the steel rod is controlled, so that the actual working state of the steel rod can be fully simulated, which is conducive to obtaining real and reliable test data.

[0052] In addition, the present invention also provides a test method of a rubber roller simulation test machine, which uses the above-mentioned simulation test machine to perform a test, and specifically includes the following steps:

[0053] a. After adjusting the winding roller 1 and the unwinding roller 2 to implement angle positioning, the steel strip 5 is assembled on the winding roller 1, the unwinding roller 2 and the lower roller 3;

[0054] b. Start the variable frequency motor 9 for driving the lower roller 3 to rotate, and adjust its speed to 50-1000r / min;

[0055] c. Adjust the positions of the lower roller 3 and the upper roller 4 so that the upper roller 4 is pressed on the lower roller 3, and adjust the grinding pressure of the lower roller 3 and the upper roller 4 on the steel strip 5;

[0056] d. Regularly detect the temperature of different positions on each roller surface and record the relationship between time and temperature;

[0057] e. Stop and start the machine at irregular intervals or start and stop the machine continuously to check the appearance and hardness of the rubber layer to obtain the test data to complete the simulation test of the rubber roller.

[0058] As an implementation mode, in this embodiment, when the upper roller 4 and the lower roller 3 are grinding the steel belt 5, a solution is dripped at the same time. The solution components can be proportioned according to the actual working environment of the rubber roller to fully reflect the conditions of the upper and lower rollers grinding the steel belt 5 under different working media, thereby improving the authenticity and reliability of the data obtained.

[0059] Preferably, in order to improve the adaptability of the simulation testing machine of the present invention, the winding roller 1 and the unwinding roller 2 in step a are support rollers or steering rollers; the upper roller 4 in step c is a squeeze roller upper roller or a pressure roller, and the lower roller 3 is a squeeze roller lower roller or a steering roller.

[0060] Furthermore, when the temperature at different positions of the roller surface is detected at regular intervals in step d of the present invention, the relationship between time, temperature and pressure is recorded every 45-60 minutes, and the temperature at both ends and in the middle of the rubber layer is recorded to check the appearance of the rubber layer; finally, the diameter, hardness and appearance of the rubber roller after shutdown or completion of the test are recorded respectively.

[0061] In order to simulate the working state of working rolls of different grades, after the test in step e is completed, the upper roll 4 is raised and the steel belt 5 is removed. After cleaning, different types of roll bodies are replaced according to the needs of the simulated environment, and then the test is repeated according to steps a to e to establish test data of rubber rollers of different materials or roller types in different production lines and workstations.

[0062] Therefore, the simulation testing machine of the present invention can simulate the continuous or intermittent operation of rubber rollers at different workstations such as squeeze rollers, steering rollers and pressure rollers, as well as medium and high rollers, grooved rollers and flat rollers in steel plants by changing roller bodies of different materials or different roller shapes, and the rubber layer's anti-extrusion deformation performance, wear resistance and bonding performance.

[0063] The simulation testing machine test method of the present invention establishes test data of rubber rollers of different materials in different production lines and workstations, systematically guides the design, research and development and production process of rubber roller rubber materials to achieve the optimal combination, and effectively improves material performance and rubber layer reliability.
