[0002] Sheet metal processing is a precision manufacturing technology widely used in many fields, and the bending process is crucial to the final shape and performance of parts. In the current sheet metal processing process, the bending machine plays a core role. It uses a series of components such as brackets, upper and lower workbenches, clamping plates, bending upper and lower dies, etc. to perform precise bending operations on sheet metal. However, due to the influence of various factors, the accuracy of the bending angle is often challenged, which is directly related to the overall quality of the product.

[0003] In order to overcome this problem, bending angle correction devices came into being. These devices are installed on the bending machine and can monitor the bending angle in real time and make necessary adjustments to ensure that the accuracy of the angle meets the design requirements.

[0020] As attached Figure 1 To Attachment Figure 3 As shown:

[0021] The utility model provides a right-angle bending sheet metal angle calibration device, comprising a calibration base 1, a conveying calibration integrated mechanism 2, a bracket 3, a cylinder 4 and a calibration head 5, wherein the conveying calibration integrated mechanism 2 and the bracket 3 are fixedly installed above the calibration base 1, the cylinder 4 is fixedly installed on the bracket 3, and the output end of the cylinder 4 is fixed to the calibration head 5.

[0022] The integrated conveying and calibration mechanism 2 includes a calibration seat 21, a docking groove 22, a conveying base 23, a protective side plate 24, a conveyor belt 25, a conveying motor 26, a groove 27 and a transition conveyor belt 28. The calibration seat 21 and the conveying base 23 are fixedly mounted on the calibration base 1; docking grooves 22 that match the conveying base 23 and the conveyor belt 25 are provided on both sides of the calibration seat 21; there are two conveying bases 23 in total, and conveying rollers are movably mounted on the two conveying bases 23 and the protective side plates 24, and the conveying rollers are equipped with the conveying belt 25, and the output end of a single conveying motor 26 is fixed to a single conveying roller; a conveying roller is rotatably mounted in the groove 27 provided on the inner side of the calibration seat 21, and the conveying roller in the groove 27 is equipped with a transition conveyor belt 28, one of the conveying rollers in the groove 27 is fixed to the output end of the conveying motor 26, and a plurality of conveying motors 26 are provided; the conveying motor 26 is fixedly mounted on the protective side plates 24 or the calibration seat 21. The integrated conveying and calibration mechanism 2 not only completely gets rid of the tedious steps of manual loading and unloading, but also has the function of autonomous positioning limitation, eliminating the need to manually adjust the placement position of the sheet metal multiple times before calibration. Embodiment 1:

[0023] Specifically, the calibration seat 21 is an overall "concave"-shaped structure, and the angle of the recessed area set above the calibration seat 21 is a right angle. The precise angle design ensures the angle accuracy of the sheet metal during the bending process. The calibration seat 21 is located directly below the calibration head 5, which not only ensures the stability of the sheet metal during the calibration process, but also improves the accuracy of the calibration; the grooves 27 are symmetrically arranged above the inner and outer surfaces of the recessed area of ​​the calibration seat 21.

[0024] Specifically, the protective side plate 24, the conveyor belt 25, the conveying motor 26 and the conveying roller are the conveying mechanism, and there are two groups of the conveying mechanism, two in a group, and the two groups of conveying mechanisms are divided into a loading conveying mechanism and a falling conveying mechanism, which are respectively located on both sides of the calibration seat 21 to ensure the smooth flow of the sheet metal during the processing. The two conveying mechanisms are installed obliquely on the conveying base 23 and are mirrored to each other, so that the sheet metal can be smoothly transferred from the loading conveying mechanism to the calibration seat 21 for calibration, and can smoothly leave through the falling conveying mechanism after the calibration is completed, forming a complete processing line.

[0025] Specifically, the conveying base 23 is an "M"-shaped structure, which ensures the stability of the sheet metal workpiece during the conveying process. The angle of the recessed area set above the conveying base 23 is a right angle and is flush with the inner surface of the recessed area of ​​the calibration seat 21. When the sheet metal workpiece is conveyed by the conveying mechanism, it can smoothly transition from the recessed area on the conveying base 23 to the recessed area of ​​the calibration seat 21. This design effectively reduces the friction and resistance of the sheet metal workpiece during the transmission process, thereby ensuring that the sheet metal workpiece can be accurately placed on the calibration seat 21, laying a solid foundation for subsequent bending and calibration work. At the same time, this smooth transition also reduces the labor intensity of operators and improves the efficiency of the entire processing flow.

[0026] Specifically, the conveying motor 26 is divided into two types. First, the motor fixed to the conveying roller of the conveying mechanism is called the transport motor, which is responsible for driving the conveyor belt 25 and the conveyor roller to rotate, thereby driving the sheet metal workpiece to be smoothly transported on the conveying base 23. The transport motor is fixedly mounted on the outer side of the protective side plate 24 to ensure its stable operation and effectively protect the internal mechanical structure. Another type of motor is a transition motor fixed to the conveying roller assembled with the transition conveyor belt 28. The main function of the transition motor is to drive the movement of the transition conveyor belt 28 to ensure that the sheet metal workpiece can smoothly transition from the conveying base 23 to the recessed area of ​​the calibration seat 21, and then transition to the falling conveying mechanism again, while adjusting the position of the sheet metal on the conveying base 23. The transition motor is fixedly mounted on the outside of the calibration seat 21 to better cooperate with the transition conveyor belt 28 and the calibration seat 21. Embodiment 2:

[0027] During operation, the integrated conveying and calibration mechanism 2 plays a core role. Through the precise cooperation between its "M"-shaped conveying base 23 and the calibration seat 21, the automatic conveying of the sheet metal workpiece is realized. The feeding conveying mechanism and the falling conveying mechanism are respectively located on both sides of the calibration seat 21. The transport motor drives the conveyor belt 25 and the conveyor roller to smoothly transfer the sheet metal workpiece to the recessed area of ​​the calibration seat 21. Subsequently, the transition motor is started to drive the transition conveyor belt 28 to accurately position the workpiece on the calibration seat 21. At this time, the cylinder 4 controls the calibration head 5 to descend and calibrate the sheet metal workpiece according to the preset angle. During the whole process, the "concave"-shaped calibration seat 21 and its symmetrically arranged grooves 27 provide a stable calibration environment for the workpiece, ensuring the accuracy of the calibration. After the calibration is completed, the transition motor drives the transition conveyor belt 28 again to deliver the workpiece to the falling conveying mechanism, realizing the automation of the entire calibration process, greatly improving work efficiency and reducing the need for manual operation.

[0028] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
