Description

Technical Field

[0001] The present invention relates to the technical field of intelligent industrial manufacturing, and particularly to a hot bending device with defect recognition and its usage method. Background Art

[0002] In the fields of metal processing and other material processing, bending treatment is a commonly used technique for manufacturing various mechanical components and structural elements. Traditional bending devices mostly operate in a cold state, that is, the material is processed at normal temperature. However, in many industrial applications, especially when dealing with high-strength or difficult-to-process materials, hot-state processing is particularly important. Hot-state processing refers to the material forming after being heated to a certain temperature. At this time, the plastic deformation resistance of the material is lower, making it easier to form, and the mechanical properties of the finished product are usually better.

[0003] Existing hot bending devices with defect recognition have the following deficiencies: Although existing hot bending devices have significant advantages in hot-state processing, they also bring a series of technical problems, especially in terms of precision control and quality inspection. Traditional hot bending devices mostly rely on the operator's experience for control and lack effective automatic detection and adjustment mechanisms. In the existing technology, the quality inspection of the components to be bent is mostly carried out before and after processing, rather than during the processing. This method cannot timely capture defects that may occur during the processing, such as cracks, bubbles, etc. These defects may be caused by the change of material properties under high-temperature conditions.

[0004] Under the condition of not targeting the aforementioned hot bending components, there are some scenarios in modern industry where bending is required to work in a hot environment. This not only requires heat insulation protection for the part in contact with the bending component, but also needs to consider the overall temperature. The overall equipment and its control system must be able to operate stably at high temperatures, while most existing mechanical equipment and electronic control systems are not designed to be heat-resistant. This requires the equipment to also have effective heat insulation and cooling mechanisms to ensure the stability and safety of the operation.

[0005] Therefore, there is still significant room for improvement in the existing hot bending devices in terms of automatic control, real-time quality monitoring, and high-temperature operation stability.

[0006] So we propose a hot bending device with defect recognition and its usage method to facilitate solving the problems raised above. Summary of the Invention

[0017] A method for using a hot bending device with defect identification includes the following steps: S1. First, according to the position of the feeding device of the element to be bent, adjust the horizontal and vertical positions of the inspection table frame, the first bending table frame, the second bending table frame, and the tail wire frame to dock with the output end of the feeding device, and wait for the element to be bent to enter the hot bending device. The heat insulation mechanism will cool the inspection table frame, the first bending table frame, the second bending table frame, and the tail wire frame to ensure stable operation in a hot environment above 100°C. S2: With the help of the roller power mechanism, the element to be bent drives at least one driving roller and a plurality of driven roller bodies, so that the element to be bent forms a linear motion with controllable speed in the hot bending device, and successively passes through the inspection table body, the first bending table body, the center line alignment table, the second bending table, and the tail wire table. Before passing through the first bending table body and the second bending table, the element to be bent will first move linearly through the cooperation of the driving roller and the driven roller bodies and travel to the inspection table frame. When the element to be bent reaches the inspection table body, the non-contact detection device on the lower surface will receive a signal and start shooting. At the same time, S201: The non-contact detection device on the upper surface will also perform non-contact detection on the upper surface of the element to be bent. S3: After the element to be bent leaves the inspection table body, it will first enter the working area of the first bending table body. The element to be bent passes through the working area between the first bending table frame, the first left bending actuator body, and the first right bending actuator body, and then enters the working area between the first bending clamping table, the center line alignment clamping mechanism, the second bending table frame, the second left bending actuator, and the second right bending actuator. After passing through the tail wire frame, the roller power mechanism stops moving. After the element to be bent stops moving, the previously detected data of the element to be bent will be displayed. If the element to be bent is qualified in quality, the subsequent process will continue; if the quality is unqualified, it will be taken off the line for processing. S4: The qualified components to be bent continue the process. Under the combined action of the first bending clamping table, the center-aligning clamping mechanism, and the second bending clamping table, the components to be bent are centered and clamped. S5: Subsequently, the first bending table and the second bending table act together to perform bending, causing the components to be bent into a predetermined shape. Then, the first bending clamping table, the center-aligning clamping mechanism, and the second bending clamping table are loosened. S6: After that, the main body of the first bending table and the movable bending member of the second bending table are withdrawn, enabling the components to be bent to be disengaged from the hot-state bending equipment from above. S7: Then, the movable bending member returns to its initial position. Subsequently, the positions of the main body of the first bending table and the second bending table are adjusted by an automatic mechanism, and the qualified components to be bent are bent again to be bent into a predetermined shape.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention can support working in a hot-state environment, effectively bend workpieces that are still in a hot state with short online or offline times, or stably work in an externally hot-state environment. At the same time, with the help of a non-contact detection module, various characteristics of the components to be bent can be detected, effectively enhancing the quality control of the components to be bent. By the cooperation of the pulse nozzle and the external air source, the viewing window can be purged at different angles. By the cooperation of the active roller, the detection table frame, and the passive roller body, the components to be bent can travel stably on the detection table. 2. Through the cooperation of the non-contact detection equipment on the lower surface and the non-contact detection equipment on the upper surface, the present invention can comprehensively detect the bending equipment. Under the action of the drainage baffle, the overall cleanliness of the hot-state bending equipment can be ensured, thereby improving the overall operation stability of the equipment.

[0031] In the present invention, first, the element to be bent is introduced into the bending device from the direction of the detection table body 2. First, the element to be bent passes through the detection table body 2 under the action of the driving roller 201. When the element to be bent moves inside the detection table body 2, at this time, the non-contact detection device 208 on the lower surface inside the detection table body 2 will perform non-contact detection on the lower surface or multiple surfaces below the element to be bent through the window 205, and judge whether the element to be bent is qualified from various parameters. When most of the element to be bent has passed through the window 205, the part to be bent of the element to be bent must have passed the detection of the non-contact detection device 208 on the lower surface. At the same time, with the optional upper surface non-contact detection device 209, a comprehensive detection of at least the upper and lower two surfaces of the element to be bent can be realized. At the same time, the optional pressing wheel 203 during the detection process can also be used to press the element to be bent. When the detection of the element to be bent is completed, at this time, the pressing wheel 203 is withdrawn from the top of the detection table body 2, that is, to ensure that the pressing wheel 203 does not block the element to be bent from popping out from the top surface. When the element to be bent is detected to be qualified, the element to be bent will continue to the next process. If it is unqualified, other treatments will be done. When the qualified element to be bent reaches the first bending table body 3 and the second bending table 5, at this time, under the combined action of the first bending clamping table, the center line centering and clamping mechanism 402 and the second bending clamping table, the element to be bent can be centered and clamped. Subsequently, the first bending table body 3 and the second bending table 5 are used to bend it at the same time, that is, the first bender and the second bender are used under the action of the bending ejection mechanism 308, and through the fixed first lower bending rod 305 and the detachable first left bending rod 3032 and first right bending rod 3042, and at the same time through the fixed second lower bending rod and the detachable second left bending rod and second right bending rod, the element to be bent can be bent. When the bending work of the element is completed, at this time, the first bending clamping table, the center line centering and clamping mechanism 402 and the second bending clamping table are loosened, and at the same time, the first left bending rod 3032, the first right bending rod 3042, the second left bending rod and the second right bending rod are withdrawn. Subsequently, it can be ensured that the element to be bent can be detached from the top.

[0032] Among them, the first left bending rod 3032 and the first right bending rod 3042 can be detached from the first left bender body 303 and the first right bender body 304. This structure allows the element to be bent to be smoothly removed from above. A through-hole is provided on the first bending tabletop and is communicated with the inside of the first bending table base. The bottom surfaces of the first left bending clamping block body 306 and the first right bending clamping block body 307 are respectively fixed to the movable ends of the first clamping block linear motor 3061 and the second clamping block linear motor 3071. The second bending table 5 and the first bending table body 3 are in a mirror image relationship, and all components correspond one by one at the mirror image positions.

[0033] Among them, the above-mentioned hot environment generally refers to a working environment above 100°C. While being applicable to hot scenarios, it does not mean that this hot bending device cannot or is not good at dealing with normal detection.

[0034] Regarding the non-contact measurement or detection device or module mentioned in this hot bending device, it can be considered that based on the existing technology, any device that can detect the physical characteristics or visual features of the element to be bent can be any one of them or a combination of multiple modalities.
