Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plate bending angle measuring equipment, in particular to a device for real-time measuring the plate bending angle. Background Art
[0002] At present, in the sheet metal processing process, due to differences in processing temperature, sheet quality, etc., it is difficult to control the springback amount of sheets of the same specification after bending, which affects the angle after bending. Production personnel need to measure repeatedly to ensure that the angle after bending meets the requirements. Therefore, a device that can provide real-time feedback on the bending angle and springback amount is needed to save the process of repeated measurements.
[0003] In the current measurement process, the angle measurement of bent parts mostly uses traditional measuring tools such as vernier calipers and protractors. The measurement is not easy and the error is large. In addition, the workpiece needs to be removed from the bending machine during the measurement process to measure the bending angle. Manual measurement is difficult to control and standardize. In addition, the inconvenience and time-consuming and labor-intensive disassembly and inspection often lead to some production personnel with insufficient safety awareness to violate regulations and measure angles directly under the bending knife, increasing the probability of casualties.

[0009] The beneficial effects of the utility model are as follows: the utility model provides a device for real-time measurement of the bending angle of a plate, wherein the scale arm and the measuring arm are mainly used for measurement, the scale plate is provided with scale lines for indicating readings, the magnetic block plays an auxiliary role in strengthening the fixation, and can ensure that the iron plate does not fall off when it is in the fixing groove one and the fixing groove two, so that the device can be moved to the position of the edge of the plate, the retaining spring plays a role in connection and tightening, and the design of the connecting shaft limits the rotation of the scale plate around the axis, thereby ensuring that the relative position of the scale lines and the scale arm remain unchanged, and the setting of several clamping tables can be suitable for plates of different sizes. The device has a simple structure and high reliability.

The intersection point of the scale arm and the measuring arm intersects with the axis of the dial, and the dial installed on the scale arm is fixed relative to the scale arm. When bending, the included angle between the measuring arm and the scale arm changes, and at the same time, the pointer segment on the measuring arm will rotate around the axis of the dial, and the rotation angle will be indicated on the dial to realize the real-time display of the bending angle. The device has a wide range of applications and a high degree of automation. Automatic measurement can reduce human operation errors, improve accuracy, and provide real-time feedback of angle values. It has high safety and reduces the probability of safety hazards caused by personnel's illegal measurement operations. BRIEF DESCRIPTION OF THE DRAWINGS
