However, the traditional rolling machine adopts the mode of periodic manual measurement and adjustment of rolling angle, which is difficult to meet this demand. The main problems are:

[0003] 1. The periodic manual measurement gap mode cannot monitor and correct the rolling angle change in real time. With the extension of rolling time, the lubrication state and the degree of wear of the parts change, so the pressing angle cannot be maintained all the time. The time interval of manual measurement is difficult to achieve timely feedback, and the thickness precision of the product is reduced.

[0004] 2. The use of periodic manual measurement is prone to measurement error, and cannot respond quickly to emergency situations. The subjective influence of the operator may lead to inaccurate measurement results, and the long response time may result in a large number of defective products.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments, but these specific embodiments do not limit the scope of protection of the present invention in any way.

[0030] Example 1

[0031] like Figures 1-5 As shown, an adaptive calibration rolling mill includes a frame 1, a base 2 mounted on the frame 1, and a rolling mechanism 3 mounted above the base 2. The inner walls of the frame 1 are provided with rails 82 on both sides. The rolling mechanism 3 is connected to the rails 82 on both sides and moves up and down along the rails 82. The bottom of the rolling mechanism 3 is provided with a rolling blade 4. The base 2 includes a platform 5 for placing steel plates. The platform 5 is provided with a curvature detection device 6 and an adaptive adjustment device 7 for adjusting the platform 5. A feeding mechanism 8 is also provided on the other side of the platform 5. A fixing mechanism is provided on the feeding mechanism 8.

[0032] In this embodiment, a power source is provided at the top of the frame 1. The power source is a hydraulic cylinder 9. The hydraulic cylinder 9 is connected to and drives the rolling mechanism 3 to move up or down along the tracks 82 on both sides of the frame 1. A control console 10 is provided on one side of the frame 1 to control the operation of the hydraulic cylinder 9. The control console 10 is not only connected to and controls the operation of the hydraulic cylinder 9, but also connected to an adaptive adjustment device 7.

[0033] The rolling mechanism 3 comprises a plurality of fixed knife seats 31 arranged at the bottom of the lifting arm, a clamping groove 32 for installing the rolling blade 4 is arranged in the fixed knife seat 31, the rolling blade 4 can be clamped into one clamping groove 32 or a plurality of clamping grooves 32, and the clamping groove 32 is provided with an adjusting hole. Through the design of the clamping groove 32 and the adjusting hole of the rolling blade 4, the rolling blade 4 can be quickly installed and disassembled. When the blade wears or different rolling shapes are required, the operator can quickly replace the blade, reduce downtime, and improve production efficiency. Since the blade can be clamped into one or more clamping grooves 32 and can be fine-tuned with the help of the adjusting hole, the switching of different rolling requirements can be easily realized, the rolling of steel plates of different thicknesses and shapes can be adapted, and the adaptability and flexibility of the rolling machine tool are enhanced.

[0034] The bottom of the rolling blade 4 is in a V-shaped structure or a U-shaped structure, and the V-shaped structure is selected in the embodiment. The rolling blade 4 is made of a material with high wear resistance, hardness, corrosion resistance and thermal stability, such as alloy tool steel, hard alloy steel, heat-treated steel, tungsten steel or high-speed steel. In the embodiment, tungsten steel is preferentially selected.

[0035] In addition, the curvature detection device 6 arranged on the machine base 2 can monitor the bending degree of the steel plate in real time, that is, the bending condition of the steel plate below the rolling mechanism 3. The curvature detection device 6 comprises:

[0036] One of a laser sensor, a fiber sensor, a displacement sensor or other similar devices is selected in the embodiment, which can scan the shape and curve of the surface of the steel plate in real time, so as to know the bending degree of the steel plate.

[0037] A data acquisition unit is responsible for receiving coordinate points, angles or other related parameter data about the curve shape of the steel plate from the laser sensor, and processing and analyzing the data.

[0038] The data acquisition unit sends the collected data to the console 10, and the console 10 is provided with a display screen, which presents the coordinate points, angles or other related parameter data about the curve shape of the steel plate on the display screen.

[0039] The data obtained by the curvature detection device 6 can be used to judge the thickness and surface quality of the steel plate. With the extension of the rolling time, the change of the lubrication state and the degree of part wear, the bending degree of the steel plate may change. The curvature detection device 6 can perform self-adaptive calibration on the rolling mechanism 3 on the basis of real-time monitoring, so as to ensure that the rolling angle of the steel plate always remains within the target range, thereby solving the problem of the decrease in the thickness precision of the product.

[0040] The base 5 is in the shape of X as a whole, and the base 5 comprises four V-shaped regions. In this embodiment, the base 5 is formed by splicing two V-shaped workpieces around a support shaft, and the self-adaptive adjusting device 7 is arranged on each of the front and rear sides of the base 5. The self-adaptive adjusting device 7 is a hydraulic telescopic rod 71 fixed on the machine base 2 and arranged obliquely, and the end of the hydraulic telescopic rod 71 in contact with the base 5 is provided with a movable oblique pushing surface 72 matched with the obliquity of the outer surface of the workpiece. In operation, the two V-shaped workpieces are pushed towards each other by the oblique pushing surface 72 of the hydraulic telescopic rod 71, so as to change the angle of the included angle.

[0041] The feeding mechanism 8 comprises a support seat 81 in the shape of a concave structure, and rails 82 are arranged on the two sides in the interior of the support seat 81. The rails 82 are provided with electrical spring clamps 83 (i.e. fixing mechanisms). The user inserts the steel plate to be rolled into the electrical spring clamps 83, and the electrical spring clamps 83 are controlled to run to the upper side of the base 5 under the automatic program control command of the control console 10. Although the bottom of the steel plate is raised when the rolling blade 4 is pressed, the steel plate is still kept in the electrical spring clamps 83. If there is no electrical spring clamp 83, but a common belt pulley or a common clamping piece is used for conveying, the rolled steel plate will either fall out of the working area or the steel plate cannot be normally raised at the rear end, which leads to rolling failure. Therefore, due to the inertia of the spring, the electrical spring clamps 83 can also clamp the rolled steel plate, and then the steel plate is sent back along the conveying direction or continues to be conveyed in other conveying directions. The automatic control of the electrical spring clamps 83 makes the feeding process more efficient and accurate, and the feeding, fixing and releasing of the steel plate can be quickly completed.

[0042] Through the design of the hydraulic telescopic rod 71 and the oblique pushing surface 72, the base 5 can realize self-adaptive adjustment. According to the real-time data obtained by the curvature detection device 6, the self-adaptive adjusting device 7 can quickly and accurately adjust the oblique angle of the base 5, so that the rolling mechanism 3 can be automatically calibrated according to different steel plate curvatures, and the steel plate can be ensured to be subjected to a suitable pressing angle in the rolling process.

[0043] The hydraulic telescopic rod 71 of the self-adaptive adjusting device 7 can quickly adjust the oblique angle of the base 5, and according to the steel plate curvature data obtained by the laser sensor, the adjusting device can be finely adjusted to ensure the accuracy and stability of the adjustment. In this way, not only the change of the steel plate curvature can be responded in time, but also the error caused by manual adjustment can be avoided.

[0044] The introduction of the self-adaptive adjusting device can reduce the dependence on manual intervention, thereby saving the adjustment time and ensuring the rolling precision and consistency. By reducing the downtime and improving the adjustment efficiency, the production efficiency can be improved. At the same time, the stable rolling angle can ensure the thickness precision and surface quality of the steel plate, and improve the quality level of the product.

[0045] The introduction of the adaptive adjustment device 7 enables the rolling machine to achieve a higher degree of automation and intelligence. Through the linkage of the laser sensor, the console 10 and the adaptive adjustment device 7, the entire rolling process can be realized under automatic control, improving the intelligent level of the production line.

[0046] The working principle and method of the self-adaptive calibration rolling machine of the present application are as follows:

[0047] 1. Preparation: Ensure that the rolling machine and related equipment are in the closed state, and check the normal operation of the hydraulic cylinder 9, the curvature detection device 6, the adaptive adjustment device 7 and other components.

[0048] 2. Place the steel plate: Move the steel plate to be rolled to the base 5 on the machine base 2 by the electrical spring clamp 83 along the track 82 to the base 5.

[0049] 3. Start the power source: Turn on the power source switch on the console 10 to start the hydraulic cylinder 9, and make the rolling mechanism 3 move up or down along the track 82 on both sides of the rack 1 to adjust the position of the rolling blade 4.

[0050] 4. Adaptive calibration: Start the adaptive adjustment device 7, real-time monitor the curvature of the steel plate according to the data obtained by the curvature detection device 6, and automatically adjust the inclination angle of the base 5 to maintain the appropriate pressing angle of the rolling blade 4 and the steel plate.

[0051] 5. Start rolling: Press the button on the console 10, and the rolling machine automatically starts working. The hydraulic cylinder 9 drives the rolling blade 4 to rise or press down to make it closely contact with the steel plate for rolling.

[0052] 6. During rolling: Monitor the display screen on the console 10 to real-time understand the curve shape, angle and other parameter data of the steel plate. If the curvature of the steel plate is found to change, the adaptive adjustment device 7 will dynamically adjust to maintain the appropriate rolling angle.

[0053] 7. Quick replacement of the blade: Replace the rolling blade 4 according to the requirements to adapt to the blade wear or different rolling requirements.

[0054] 8. Complete rolling: Stop the hydraulic cylinder 9 to make the rolling blade 4 return to the initial position. Turn off the power source and related equipment, take out the rolled steel plate and move to the next process.

[0055] Example 2

[0056] Reference Figure 6Different from example 1, the base in example 2 is not composed of two V-shaped workpieces spliced around a supporting shaft, but an X-shaped workpiece sleeved on a rotating shaft. In the four V-shaped regions of the X-shaped workpiece, the included angles of each V-shaped region are different. The rotating shaft is connected with rotating devices on both sides. The rotating devices cooperate with the self-adapting devices to fix and support the V-shaped regions with different included angles when the V-shaped regions are adjusted. The X-shaped workpiece is prevented from rotating and deviating when the steel plate is placed.
