Technical Field
[0001] This utility model belongs to the field of metal plate bending processing technology, specifically referring to a metal plate auxiliary right-angle bending device. Background Technology
[0002] Right-angle bending is a common process in metal sheet bending, widely used in the production of various metal structural parts in the manufacturing industry. Traditional bending equipment typically uses a bending machine to bend metal sheets at a preset angle, mainly relying on mechanical limit devices to control the bending angle. However, this method is insufficient in terms of precision and lacks sufficient repeatability, especially in large-scale production or high-precision applications, which can easily lead to inaccurate product angles or scrap, thereby increasing production costs.
[0003] While existing bending equipment incorporates some sensors and electrical control systems, most still lack real-time monitoring and adjustment capabilities, failing to effectively address errors during the bending process. Traditional equipment typically struggles to provide real-time measurement feedback on the angle of the metal sheet, resulting in minor deviations in the bending angle going uncorrected and further impacting bending quality. To meet the demands of modern production for high precision and efficiency, a new bending device is needed that can monitor and automatically adjust the bending process in real time, thereby effectively improving bending accuracy and production efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, they should not be construed as limitations on this utility model.
[0020] like Figures 1-7 As shown, the bending device proposed in this embodiment is used for right-angle bending of metal plates. The structure includes a laser-assisted mechanism 100 and a hydraulic bending mechanism 200. The laser-assisted mechanism 100 is mounted on the hydraulic bending mechanism 200, which is used to bend the metal plate. The laser-assisted mechanism 100 is used to assist in detecting the bending angle of the metal plate. The laser-assisted mechanism 100 and the hydraulic bending mechanism 200 work together to ensure real-time monitoring and adjustment during the bending process of the metal plate, thereby achieving the purpose of high-precision bending.
[0021] The hydraulic bending mechanism 200 includes a lifting upper mold 204 and a fixed lower mold 205. The lifting upper mold 204 is raised and lowered relative to the fixed lower mold 205. In actual use, the metal plate is placed flat on the fixed lower mold 205, and the lifting upper mold 204 descends and applies pressure to complete the bending operation of the metal plate. By adjusting the angle between the lifting upper mold 204 and the fixed lower mold 205, precise bending of metal plates with different thicknesses and deflections can be achieved to meet different angles and bending requirements. This allows the operator to flexibly adjust the equipment according to the different specifications and needs of the metal plate, ensuring the consistency and high precision of the bending effect.
[0022] The laser-assisted mechanism 100 proposed in this embodiment is mainly used to assist in detecting the bending angle of the metal plate, so as to ensure that the angle change of the metal plate can be monitored in real time during the bending process and to ensure accuracy. The structure of the laser-assisted mechanism 100 includes a snap-fit clamp 110, which is fixed on the lifting upper mold 204 to ensure that the laser-assisted mechanism and the hydraulic bending mechanism 200 are closely matched and can be adjusted synchronously with the movement of the lifting upper mold 204.
[0023] A laser rangefinder 112 is mounted on the latching clamp 110. The laser rangefinder 112 is connected to the latching clamp 110 via a rotatable connection, allowing the rangefinder to be adjusted within a certain range. The core components of the laser rangefinder 112 include a first laser generator 114 and a second laser generator 115. These two laser generators are located on the laser rangefinder 112 and are on the same plane in the vertical direction. During use, the laser rangefinder 112 controls the first laser generator 114 and the second laser generator 115 to emit lasers. These lasers irradiate the surface of the metal plate and are reflected back. The laser rangefinder obtains two sets of distance data; these two sets of data represent the distances between the first laser generator 114 and the second laser generator 115 and the metal plate, respectively. If the two sets of distance data are equal, it means that the planes of the first laser generator 114 and the second laser generator 115 are parallel to the plane of the metal plate. This result shows that the angle of the laser rangefinder 112 is consistent with the angle of the metal plate, which can effectively monitor whether the bending angle of the metal plate meets the predetermined requirements. This real-time monitoring method allows errors in the bending process to be adjusted in a timely manner, improves bending accuracy, and ensures that the metal plate is bent in place.
[0024] The laser rangefinder 112 in the laser-assisted mechanism 100 can detect the bending angle of the metal plate in real time to ensure bending accuracy. During the bending process, the first laser generator 114 and the second laser generator 115 respectively irradiate the surface of the metal plate and measure two sets of distance data to determine whether the angle between the laser rangefinder 112 and the metal plate is consistent. This avoids the problem of insufficient accuracy of traditional mechanical limit devices and reflects in real time whether the metal plate is bent at the predetermined angle, thus avoiding deviations during the bending process.
[0025] In addition, the laser rangefinder head 112 is fixed by the snap-fit clamp 110 to ensure that it remains in a fixed position with the lifting upper mold 204. The equipment can automatically monitor and adjust the bending angle, reduce manual intervention, improve production efficiency, and is highly adaptable. It can handle metal plates of different materials and specifications, while improving production automation and precision.
[0026] The buckle clamp 110 proposed in this embodiment is provided with a rotating base 111, and the laser rangefinder 112 is rotatably mounted on the rotating base 111, which enables the angle adjustment of the laser rangefinder and ensures the flexibility and accuracy in the measurement process. The rotating base 111 provides a stable rotation support for the laser rangefinder 112, which can adapt to the adjustment requirements of different bending angles. The end of the laser rangefinder 112 is provided with a reference plate 113, which is used to ensure the stability of the position of the laser generator relative to the metal plate, thereby ensuring the consistency and accuracy in the measurement process.
[0027] During the bending process, when the reference plate 113 is parallel to the metal plate, the lasers emitted by the first laser generator 114 and the second laser generator 115 are at the same distance from the metal plate, which defines the measurement relationship between the laser generator and the metal plate. If the two distances are consistent, it indicates that the angle of the laser ranging head is parallel to the metal plate, which can accurately monitor the bending process of the metal plate and ensure bending accuracy. The reference plate 113 plays a key positioning role, avoiding interference from changes in the position of the laser generator, and further improving the stability and measurement accuracy of the system.
[0028] The rotating base 111 proposed in this embodiment is provided with an angle scale 117 on its side. The angle scale 117 is closely matched with the rotation angle of the laser rangefinder 112, which can accurately display the tilt angle of the laser rangefinder 112. In order to further improve the accuracy of measurement, the laser rangefinder 112 is provided with an angle pointer 116, which corresponds to the angle scale 117. Through the cooperation of the angle pointer 116 and the angle scale 117, the user can intuitively read the tilt angle of the laser rangefinder 112.
[0029] During the bending process, the operator can quickly and accurately adjust the angle of the laser rangefinder 112 to measure and monitor according to the predetermined angle. Through this angle adjustment system, the laser rangefinder 112 can accurately measure the angle of the metal plate according to the actual bending requirements, further improving the bending accuracy and avoiding bending deviations caused by angle errors, thereby ensuring the final processing quality.
[0030] The laser-assisted mechanism 100 proposed in this embodiment includes a digital display processor 120, which is mounted on a snap-fit fixture 110 to facilitate real-time monitoring of the measurement results of the laser rangefinder 112 by the operator. The digital display processor 120 is connected to the laser rangefinder 112 via a data transmission line 121, which passes through a wiring hole 118 on the rotating base 111 to ensure that the data transmission line 121 can smoothly connect to the laser rangefinder 112 and transmit measurement data. The configuration of the data transmission line 121 allows the real-time measurement results of the laser rangefinder 112 to be displayed by the digital display processor 120, making it convenient for the operator to view the distance data between the laser rangefinder 112 and the metal plate in real time.
[0031] By combining the measurement results of the laser rangefinder 112 with the digital display processor 120, the laser rangefinder 112 can transmit the measurement data to the operator in real time, avoiding errors that may be caused by manual estimation or misoperation, and improving the accuracy and efficiency of the bending process. Through the digital display processor 120, the operator can accurately control the bending angle of the metal plate, ensuring that the metal plate is bent precisely at the predetermined angle, thereby improving bending quality and production efficiency.
[0032] The hydraulic bending mechanism 200 proposed in this embodiment adopts a combined structure of a lifting platform 201 and a fixed platform 202, which facilitates precise bending of the metal plate. The lifting platform 201 is slidably connected to the mechanical support 203, ensuring that the lifting platform 201 can move up and down smoothly. During the bending process, the height of the lifting platform 201 is adjusted according to different bending requirements to precisely control the bending angle of the metal plate. The fixed platform 202 is fixedly connected to the mechanical support 203, providing stable support and ensuring the stability of the platform during the bending process. The upper lifting mold 204 is set on the lifting platform 201, and the lower fixed mold 205 is set on the fixed platform 202. In use, the upper lifting mold 204 and the lower fixed mold 205 move relative to each other through a hydraulic drive system to apply pressure to the metal plate, thereby completing the bending of the metal plate.
[0033] The hydraulic bending mechanism 200 proposed in this embodiment is equipped with a hydraulic cylinder 206 and a traction spring 207 on a mechanical support 203 to optimize the motion control of the lifting platform 201. The hydraulic cylinder 206 is connected to the lifting platform 201 and is configured to drive the lifting and lowering movement of the lifting platform 201. The height of the lifting platform 201 is precisely adjusted through the hydraulic drive system, thereby achieving precise bending of the metal plate. The hydraulic cylinder 206 enables the lifting platform 201 to move smoothly under heavy load, ensuring uniform pressure distribution during the bending process and adapting to metal plates of different thicknesses and materials.
[0034] Meanwhile, the lifting platform 201 is connected to the traction spring 207. The function of the traction spring 207 is to ensure that the lifting platform 201 can automatically return to its original position after completing the bending action. After the lifting platform 201 completes the bending operation on the metal plate, the traction spring 207 provides elastic force to quickly restore the lifting platform 201 to its initial position, avoiding long-term pressure on the mechanical parts and helping to improve the working efficiency and reliability of the equipment. It can maintain high precision and stability in high-frequency operation, and enhance the service life and operating performance of the bending mechanism.
[0035] The mechanical support 203 proposed in this embodiment is provided with a side slide groove 208 on its side. The lifting platform 201 is slidably disposed in the side slide groove 208. The side slide groove 208 is used to guide the smooth movement of the lifting platform 201. By providing a slide groove on the side of the mechanical support 203, the lifting platform 201 can be precisely vertically raised and lowered along the slide groove, reducing the friction between the lifting platform 201 and the support, reducing wear and resistance during operation, and ensuring the smoothness and stability of the lifting process.
[0036] The side groove 208 prevents the lifting platform 201 from tilting or unevenly lifting during movement, thus improving the accuracy and reliability of the bending operation. In addition, the groove also optimizes the load-bearing capacity of the lifting platform 201, enabling it to withstand larger loads while maintaining its stability, ensuring that the hydraulic bending mechanism 200 can maintain good performance and durability under high load or long-term use.
[0037] The first laser generator 114 and the second laser generator 115 proposed in this embodiment employ semiconductor lasers. These lasers have a small size and high efficiency, making them suitable for high-precision measurement applications. The working principle of semiconductor lasers is based on the generation of light radiation by current passing through semiconductor materials. Therefore, while providing stable laser output, they can quickly respond to external control signals, ensuring the real-time performance and accuracy of laser emission. To ensure the measurement accuracy and stability of the laser beam on the metal plate, the diameter of the laser beam emitted by the first laser generator 114 and the second laser generator 115 is controlled between 0.5 and 1 mm. This ensures the focusing ability of the laser beam, allowing the laser to concentrate on the surface of the metal plate, while avoiding measurement errors or scattering problems caused by an excessively large laser beam, thereby improving the accuracy and reliability of the measurement.
[0038] In addition, semiconductor lasers have strong anti-interference capabilities and can work stably in high-temperature or other complex environments. This is especially important for laser ranging requirements in the bending process of metal plates, because bending equipment may generate significant vibration or heat during operation. By selecting semiconductor lasers, it can be ensured that the laser-assisted detection system can still accurately measure and provide real-time feedback in such complex environments, thereby improving the reliability and accuracy of the entire bending process.
