Technical Field

[0001] This utility model relates to the field of rolling mill sleeve technology, and in particular to a device for detecting the surface wear resistance of rolling mill sleeves. Background Technology

[0002] Roll sleeves are key components in rolling mills, primarily used in the rolling process of metal materials. Their performance directly affects production efficiency and material quality. Therefore, after manufacturing, the surface quality of roll sleeves must be inspected to ensure stable operation under harsh conditions such as high temperature, high pressure, and high friction. Existing roll sleeve testing devices mainly rely on the friction of annular blocks during testing. However, these annular blocks are not replaceable, significantly reducing the service life of the testing device. Utility Model Content

[0003] The purpose of this utility model is to provide a device for testing the wear resistance of a roll sleeve surface, wherein the testing plate can be disassembled and replaced after wear, which greatly improves the service life of the testing device.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A device for testing the wear resistance of a roll sleeve surface includes a testing bracket, on which a first limit adjustment device and a second limit adjustment device are symmetrically arranged. The first limit adjustment device and the second limit adjustment device are used to clamp and adjust the position of the roll sleeve.

[0006] A limit frame is fixed inside the detection bracket. A first pressure device is provided vertically downward at the top of the limit frame, and a second pressure device is provided vertically upward at its bottom.

[0007] The first pressure device includes a first pressure cylinder, which is fixed vertically downward on the top of the limiting frame. A first arc-shaped pressure support plate is fixed on the piston rod of the first pressure cylinder, and a first arc-shaped friction detection plate is detachably screwed into the inside of the first arc-shaped pressure support plate.

[0008] The second pressure device includes a second pressure cylinder, which is fixed vertically upward at the bottom of the limiting frame. A second arc-shaped pressure support plate is fixed on the piston rod of the second pressure cylinder, and a second arc-shaped friction detection plate is detachably screwed into the inside of the second arc-shaped pressure support plate.

[0009] As an improvement, a first pressure sensor is provided at the joint between the piston rod of the first pressure cylinder and the first arc-shaped pressure support plate.

[0010] As an improvement, a second pressure sensor is provided at the joint between the piston rod of the second pressure cylinder and the second arc-shaped pressure support plate.

[0011] As an improvement: the first limit adjustment device includes a first limit adjustment cylinder, which is horizontally disposed on the left side of the detection bracket, and a first conical limit block is fixed on the piston rod of the first limit adjustment cylinder.

[0012] As an improvement: the second limit adjustment device includes a second limit adjustment cylinder, which is horizontally arranged on the right side of the detection bracket, and a second conical limit block is fixed on the piston rod of the second limit adjustment cylinder.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. The first arc-shaped friction detection plate is detachably installed on the first arc-shaped pressure support plate, and the second arc-shaped friction detection plate is detachably installed on the second arc-shaped pressure support plate. When the arc-shaped friction detection plate is damaged, it can be detached and replaced, which greatly improves the efficiency of the device.

[0015] 2. The first pressure sensor and the second pressure sensor can respectively sense the pressure of the first arc-shaped pressure support plate and the second arc-shaped pressure support plate on the roll sleeve, so that the corresponding arc-shaped friction detection plate is attached to the roll sleeve with a certain pressure, thereby better simulating the pressure during use and improving the detection effect.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Please refer to Figure 1 A device for testing the wear resistance of a roll sleeve surface includes a testing bracket 1, on which a first limit adjustment device and a second limit adjustment device are symmetrically arranged. The first limit adjustment device and the second limit adjustment device are used to clamp and adjust the position of the roll sleeve.

[0021] A limiting frame 2 is fixed inside the detection bracket 1. A first pressure device is provided vertically downward at the top of the limiting frame 2, and a second pressure device is provided vertically upward at its bottom.

[0022] The first pressure device includes a first pressure cylinder 3, which is fixed vertically downward on the top of the limiting frame 2. A first arc-shaped pressure support plate 5 is fixed on the piston rod of the first pressure cylinder 3. A first arc-shaped friction detection plate 7 is detachably screwed into the inside of the first arc-shaped pressure support plate 5.

[0023] The second pressure device includes a second pressure cylinder 4, which is vertically fixed to the bottom of the limiting frame 2. A second arc-shaped pressure support plate 6 is fixed to the piston rod of the second pressure cylinder 4. A second arc-shaped friction detection plate 8 is detachably screwed into the interior of the second arc-shaped pressure support plate 6. In this embodiment, the first arc-shaped friction detection plate 7 is detachably mounted on the first arc-shaped pressure support plate 5, and the second arc-shaped friction detection plate 8 is detachably mounted on the second arc-shaped pressure support plate 6. When the arc-shaped friction detection plate is damaged, it can be disassembled and replaced, greatly improving the efficiency of the device.

[0024] A first pressure sensor 9 is provided at the junction of the piston rod of the first pressure-applying cylinder 3 and the first arc-shaped pressure-applying support plate 5. A second pressure sensor 10 is provided at the junction of the piston rod of the second pressure-applying cylinder 4 and the second arc-shaped pressure-applying support plate 6. In this embodiment, the first pressure sensor 9 and the second pressure sensor 10 can respectively sense the pressure of the first arc-shaped pressure-applying support plate 5 and the second arc-shaped pressure-applying support plate 6 on the roll sleeve, so that the corresponding arc-shaped friction detection plate is attached to the roll sleeve with a certain pressure, thereby better simulating the pressure during use and improving the detection effect.

[0025] The first limit adjustment device includes a first limit adjustment cylinder 11, which is horizontally disposed on the left side of the detection bracket 1. A first conical limit block 13 is fixed on the piston rod of the first limit adjustment cylinder 11. The second limit adjustment device includes a second limit adjustment cylinder 12, which is horizontally disposed on the right side of the detection bracket 1. A second conical limit block 14 is fixed on the piston rod of the second limit adjustment cylinder 12.

[0026] In this embodiment, the roll sleeve can be clamped and limited between the first conical limiting block 13 and the second conical limiting block 14 under the action of the first limiting adjusting cylinder 11 and the second limiting adjusting cylinder 12. When the piston rod of the first limiting adjusting cylinder 11 shortens to the left, the piston rod of the second limiting adjusting cylinder 12 extends to the left at the same time. When the piston rod of the first limiting adjusting cylinder 11 extends to the right, the piston rod of the second limiting adjusting cylinder 12 shortens to the right at the same time, thereby realizing the friction between the roll sleeve and the two arc-shaped friction detection plates.

[0027] Working principle: The outer diameter of the roll sleeve is measured before inspection using an external laser diameter measuring instrument. Then, the roll sleeve is placed between the first conical limit block 13 and the second conical limit block 14. The first limit adjustment cylinder 11 and the second limit adjustment cylinder 12 are activated to drive the first conical limit block 13 and the second conical limit block 14 to move relative to each other, thereby clamping the roll sleeve.

[0028] Then, the first pressure cylinder 3 is activated to move downward, pressing the first arc-shaped friction detection plate 7 against the upper surface of the roll sleeve with a certain pressure. The second pressure cylinder 4 moves upward, pressing the second arc-shaped friction detection plate 8 against the lower surface of the roll sleeve with a certain pressure.

[0029] Then, the first limit adjustment cylinder 11 and the second limit adjustment cylinder 12 are activated. When the piston rod of the first limit adjustment cylinder 11 shortens to the left, the piston rod of the second limit adjustment cylinder 12 extends to the left in sync. When the piston rod of the first limit adjustment cylinder 11 extends to the right, the piston rod of the second limit adjustment cylinder 12 shortens to the right in sync, thereby realizing the friction between the roll sleeve and the two arc-shaped friction detection plates.

[0030] After a period of friction, the outer diameter of the roll sleeve is measured using an external laser diameter gauge or similar instrument. By comparing the diameter of the roll sleeve before and after friction, the wear resistance of the roll sleeve surface can be determined.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
