Description

[0002] In the manufacture of metallurgical equipment, rolls in metal rolling mills are common accessories. In the process of producing rolls, there may be surface defects caused by operating errors or poor processes, including cracks, breaks, peeling, and scratches. Surface defects not only affect the color of the rolls, but also affect the stability of the rolls, and can also indirectly affect the quality of rolling. Therefore, roll defect detection is extremely important.

[0003] In actual production, traditional roll inspection usually uses manual judgment, relying on manual touch and visual inspection to judge the degree and type of damage on the roll surface. This method is affected by manual experience and subjective factors, has low accuracy, high labor intensity, low inspection efficiency, and is prone to missed inspections and false inspections. It can only make qualitative judgments on defects but cannot make quantitative assessments. At the same time, due to the large size and weight of the roll itself and the long grinding time, in addition to affecting the quality of the rolled product, if a quality problem of the rolled product is found, returning the defective roll from the rolling production line to the grinding roll room for re-grinding also requires a lot of manpower, material resources and time costs.

The control module is electrically connected to the drive component 2, the support component 3 and the moving component 4 and is used to control the auxiliary support, fixation and driving of the rotating roller. The alarm module is used for alarm prompts.

[0042] Detection method of the new roller defect detection device:

[0043] Step 1: Install the roller to be tested.

[0044] Specifically, the staff uses the lifting equipment to place the roller on the support frame 33, and then controls the lifting part 31 to lift and lower, so that the axis of the roller is in the same straight line with the axis of the main shaft and the axis of the ejector pin 410, and the right end of the roller is connected to the main shaft and fixed on the drive component 2, and the left end of the roller is brought into contact with the thump at the end of the ejector pin 410 so that the thump holds the roller, thereby restricting the roller between the moving component 4 and the driving component 2. When the motor 21 is started, the roller is driven to rotate synchronously through the pulley transmission.

[0045] Step 2: Detection of roller surface condition.

[0046] Specifically, the lighting lamp 1 39 is not on, the opening and closing part is in the closed state, the lighting lamp 2 52 is on, and the control module controls the brightness of the lighting lamp 2 52 to be adjusted to a point where the camera 53 can clearly capture the surface of the roller. Then the motor 21 is started and the roller is driven to rotate through the pulley. The single rotation angle is α, which is a divisor of 360°.

[0047] The initial rotation angle is 0, and the angle corresponding to the center of the image captured by the camera 53 is 0+90°. The acquisition module captures the image content and feeds it back to the recognition module. The recognition module identifies whether there are cracks and scratches in the center of the image. When continuous irregular thin lines are identified, there are cracks on the surface of the roller. Feedback is sent to the alarm module and the corresponding angle at this time is recorded, which is recorded as A, A=nα+90°, n is the number of times the motor 21 is started to drive the roller to rotate when cracks are detected on the surface of the roller. This roller does not meet the production requirements; when multiple regular thin lines are identified, there are scratches on the surface of the roller. Feedback is sent to the alarm module and the corresponding angle at this time is recorded, which is recorded as B, B=mα+90°, m is the number of times the motor 21 is started to drive the roller to rotate when scratches are detected on the surface of the roller. The equipment for processing this roller needs to be repaired or replaced, which is beneficial to improving the processing quality of subsequent rollers; after completing the outer surface inspection of the roller for one week, all angles corresponding to cracks and scratches are fed back through the alarm module, and the staff will carry out targeted repairs.

[0048] Step 3: Roller profile detection.

[0049] Specifically, the lighting lamp 1 39 is on, the opening and closing part is in the open state, the lighting lamp 2 52 is off, and then the motor 21 is started. The rotation direction of the motor 21 is consistent with the rotation direction of step 2, and the roller is driven to rotate through the pulley transmission. The initial rotation angle is 0. At this time, the center of the roller image captured by the acquisition module camera 53 is black, and there is light at the roller contour, so that the image recognition module can recognize the roller contour and obtain the roller center diameter, roller edge diameter, maximum diameter and minimum diameter. The roller center diameter is recorded as D1, and the roller end diameters are recorded as D 左 and D 右 , the maximum diameter is recorded as D max , the minimum diameter is denoted as D min The recognition module also calculates the convexity of the roll according to the acquired diameter data. The convexity is recorded as Cr. The convexity is the difference between the diameter at the center of the roll and the diameter at the edge of the roll. Therefore, the convexity is divided into left and right, which are recorded as Cr respectively. 左 and Cr 右 ,Cr 左 =D1-D 左 ,Cr 右 =D1-D 右 At the same time, the convexity limit is set in the recognition module, denoted as Cr 限 .

[0050] It should be noted that, since the roller profile in the collected roller image is the surface projection of the roller, in this step, the motor 21 only needs to drive the roller to rotate 180 degrees to complete the roller profile detection for one circle.

[0051] In Cr 左 =Cr 右 =Cr 限 And D1=D max , D 左 =D 右 =D min It is an ideal state, and the convexity of the roller meets the requirements of subsequent use;

[0052] In Cr 左 =Cr 右 =Cr 限 But D1≠D max , D 左 =D 右 =D min When the roller convexity is normal, the maximum diameter is abnormal, which is the overall convexity abnormality, indicating that there is a bulge at the maximum diameter. Feedback is sent to the alarm module and the corresponding angle is recorded. After completing the contour detection of the roller for one week, the staff will grind the maximum diameter.

[0053] In Cr左 =Cr 右 =Cr 限 、D1=D max But D 左 =D 右 ≠D min When the roller convexity is normal, the minimum diameter is abnormal, which means the overall convexity is abnormal, indicating that there is a pit at the minimum diameter. Feedback is sent to the alarm module and the corresponding angle is recorded. After completing the contour detection of the roller for one week, the staff will weld and fill the minimum diameter or reprocess it to a small diameter roller.

[0054] In Cr 左 =Cr 右 =Cr 限 、D1≠D max But D 左 =D 右 ≠D min When the roller convexity is normal, the maximum diameter and minimum diameter are abnormal, which means the overall convexity is abnormal, indicating that the roller profile is deformed. Feedback is sent to the alarm module and the corresponding angle is recorded. After completing the roller profile detection for one week, the staff will weld and fill the minimum diameter, grind the maximum diameter or reprocess it to a small diameter roller.

[0055] In Cr 左 ≠Cr 右 When the convexity on the left and right sides is inconsistent, it needs to be fed back to the alarm module and the corresponding angle at this time must be recorded. After completing the contour detection of the roller for one week, the staff will use tools to adjust the contour at the corresponding angle or reprocess the roller.

[0056] After completing the profile detection of the roller for one week, if more than half of the detection results are consistent, it is caused by the equipment in the processing and production process. The alarm module will issue an alarm prompt and the staff will inspect the processing equipment to improve the processing quality of the roller and reduce the defective rate.

[0057] After completing the profile detection of the rolling mill for one circle, if the detection results are inconsistent and scattered, the staff can call up the recognition screen of the corresponding angle in this step and the recognition screen at the angle +90° corresponding to this step in step two for verification, so as to further improve the accuracy of the detection results.

[0058] Through the above steps, the surface condition and convexity of the roller can be detected, the accuracy and efficiency of roller detection can be improved, and the influence of uncertain factors can be reduced.
