Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically to an offline testing device for rolling mill brush rolls. Background Technology

[0002] As a commonly used device for metal shaping, rolling mills apply pressure to metal billets through rollers, causing them to plastically deform and thus producing the desired shapes, such as plates, pipes, or profiles. To improve the accuracy of rolling mills in shaping metals, it is usually necessary to conduct offline tests on the rolling mill rollers, measuring data such as pressure and stability during roller rotation. However, after the rollers are tested individually, the hydraulic cylinders on both sides of the rollers also need to be tested. Common testing devices have low compatibility, making the testing of hydraulic cylinders quite difficult. Utility Model Content

It is suitable for the offline independent testing of rolling mill rolls. After the roll is individually debugged, it can perform lateral movement, pressing, and rotation actions on the hydraulic cylinder on one side of the roll. At the same time, it can also perform pressing and rotation actions on the hydraulic cylinder on the other side of the roll. This facilitates the independent testing of the hydraulic cylinders on both sides of the roll, improves the stability of the rolling mill during use, and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rolling mill brush roll offline testing device, comprising an oil tank and a controller. A hydraulic motor for controlling the flow of hydraulic oil is installed on the oil tank. Five sets of valve blocks are installed on the outside of the oil tank, and the inner cavities of the five sets of valve blocks are interconnected. Three sets of valve blocks constitute a first hydraulic cylinder control oil circuit, and the other two sets of valve blocks constitute a second hydraulic cylinder control oil circuit.

The controller 2 is preferably a PLC controller, and the controller 2 is equipped with both a touch control panel and mechanical buttons to meet the needs of different situations. The controller 2 controls the operation of the electronic components in this testing device and also receives some electronic signals. The feedback signal from the components allows personnel to obtain information such as the pressure, inlet flow, and outlet flow of the hydraulic oil in the testing device in a timely manner. Preferably, an oil drain port 16 is installed on the lower side of the oil tank 1, which communicates with the bottom of its inner cavity. A removable sealing plug is provided inside the oil drain port 16. After removing the sealing plug, it is convenient for personnel to drain or replace the hydraulic oil in the oil tank 1 through the oil drain port 16. A level gauge 17 is installed on the upper side of the oil tank 1, and the measuring end of the level gauge 17 is communicated with the inner cavity of the oil tank 1. The level gauge 17 is used to detect the level information of the hydraulic oil in the oil tank 1 to assist in the use of this testing device.

[0027] A hydraulic motor 3 for controlling the flow of hydraulic oil is installed on the oil tank 1. Five sets of valve blocks 7 are installed on the outside of the oil tank 1, and the inner cavities of the five sets of valve blocks 7 are interconnected. Three sets of valve blocks 7 constitute the first hydraulic cylinder control oil circuit 5, and the other two sets of valve blocks 7 constitute the second hydraulic cylinder control oil circuit 6. The first hydraulic cylinder control oil circuit 5 is used to control the action of the hydraulic cylinder on one side of the roller, and the second hydraulic cylinder control oil circuit 6 is used to control the action of the hydraulic cylinder on the other side of the roller. By controlling them separately, it is convenient to test the hydraulic cylinders on both sides of the roller separately. The first hydraulic cylinder control oil circuit 5 includes a surging oil circuit 51, a first pressing oil circuit 52, and a second pressing oil circuit 53. The first hydraulic cylinder control circuit 53 is used to control the surging, pressing, and rotating actions of one of the hydraulic cylinders. The second hydraulic cylinder control circuit 6 includes a second pressing circuit 61 and a second rotating circuit 62. The second hydraulic cylinder control circuit 6 is used to control the pressing and rotating actions of the other hydraulic cylinder. Each set of hydraulic circuits uses rubber hoses to deliver hydraulic oil for operation. Each valve block 7 has two rubber hoses, which are used for oil inlet and return during hydraulic cylinder testing. A reversing valve 8 is installed on the valve block 7. The hydraulic cylinder action adjustment is realized by switching the oil circuit through the reversing valve 8, which facilitates the action testing of the hydraulic cylinder.

[0028] The oil tank 1 is equipped with a main oil circuit that connects to each group of valve blocks 7, and an overflow valve 4 for monitoring the flow of hydraulic oil in the main oil circuit is installed on the outside of the oil tank 1. When the hydraulic motor 3 drives the hydraulic oil into the valve block 7, it flows through the overflow valve 4. The overflow valve 4 determines whether the hydraulic cylinder has been activated by monitoring the flow of hydraulic oil in the oil circuit. If the hydraulic cylinder has not been activated, the overflow valve 4 controls the hydraulic oil to flow back to the oil tank 1, which serves as a protection function.

[0029] One side of the valve block 7 has an outlet communicating with its inner cavity, and the other side of the valve block 7 has an inlet 10 communicating with its inner cavity. The outlets of two adjacent sets of valve blocks 7 are connected to the inlets 10 for the flow of hydraulic oil in each set of valve blocks 7. Plugs 9 are installed in the inlets 10 of the end valve block 7 and in the outlets of the tail valve block 7. The plugs 9 are detachable and seal the outlets and inlets 10 that are not connected to the valve block 7 to prevent oil leakage.

[0030] Five valve blocks 7 constitute a valve block group. A pressure gauge 15 is installed on the side of the valve block 7 at the end, and the detection end of the pressure gauge 15 is located inside the valve block 7. The pressure gauge 15 is used to monitor the overall pressure in the valve block group, which is convenient for personnel to obtain the internal pressure of the valve block group offline. A pressure sensor 13 is installed on the side of the valve block 7 at the tail end, and the detection end of the pressure sensor 13 is located inside the valve block 7. The pressure information measured by the pressure sensor 13 is fed back to the controller 2, and the controller 2 displays the pressure information online, which is convenient for personnel to obtain the internal pressure data of the valve block group online. A pressure measuring point 14 is set on the side of the valve block 7, and the pressure measuring point 14 is connected to the inner cavity of the valve block 7. The pressure measuring point 14 is used for pressure testing of a single valve block 7.

[0031] A hand valve 11 is installed on one of the hoses mounted on the valve block 7. The hand valve 11 allows personnel to mechanically control the hydraulic oil in the hose. A check valve 12 is installed on another hose mounted on the valve block 7. The check valve 12 is used for the one-way flow of hydraulic oil in the hose, which allows the valve block 7 to control the flow of hydraulic oil to realize the action of the hydraulic cylinder.

[0032] It also includes a storage rack for storing hoses. The storage rack includes a support frame 18, on which several storage trays 19 are rotatably mounted. The several storage trays 19 are evenly arranged from top to bottom along the height direction of the support frame 18. The storage trays 19 on the support frame 18 are used for storing and placing hoses. Because the processes of each stage are not synchronized, the hoses that are not used or have been used are placed in the storage rack.

[0033] This rolling mill brush roll offline testing device is suitable for offline individual testing of rolling mill rolls. After the roll has been individually debugged, it can perform lateral movement, pressing, and rotation actions on the hydraulic cylinder on one side of the roll, and can also perform pressing and rotation actions on the hydraulic cylinder on the other side of the roll. This facilitates individual testing of the hydraulic cylinders on both sides of the roll and improves the stability of the rolling mill during use.
