[0008] In order to facilitate the adjustment of the position of the abutment plate, as a preferred steel plate bending device of the utility model that is convenient for measuring the bending angle, the upper end face of the baffle plate is threadedly connected with a screw rod, one end of the screw rod extends to the bottom of the baffle plate and is fixedly connected to the abutment plate.

[0009] In order to drive the two measuring rods to reset, as a preferred embodiment of the present invention of a steel plate bending device that is convenient for measuring bending angles, a second spring is fixedly connected between the two measuring rods and the angle disk.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] During the bending process, the lower pressure block squeezes the bending line of the steel plate into the bending groove, causing the front and rear ends of the steel plate to tilt up. While the steel plate tilts up, the steel plate cooperates with the baffle to drive the two measuring rods to rotate, and the bending angle of the steel plate is measured by the two measuring rods. At the same time, the lower pressure rod cooperates with the support plate to push the angle plate downward. Since the support block is flush with the support plate and the measuring rod, the bending part of the steel plate can continue to remain flush with the rotation point of the two measuring rods, thereby making the two measuring rods more accurate in measuring the bending angle of the steel plate. After the bending is completed, the angle between the two measuring rods is the bending angle of the steel plate, thereby measuring the bending angle of the steel plate.

[0024] During the bending process, the lower pressing block 3 squeezes the bending line of the steel plate into the bending groove 5, so that the front and rear ends of the steel plate are tilted. When the steel plate is tilted, the steel plate cooperates with the baffle plate 12 to drive the two measuring rods 11 to rotate, and the bending angle of the steel plate is measured by the two measuring rods 11. At the same time, the lower pressing rod 14 cooperates with the support plate 13 to push the angle plate 9 to move downward. Since the support block 4 is flush with the support plate 13 and the measuring rod 11, the bending part of the steel plate can be continuously kept flush with the rotation point of the two measuring rods 11, so that the two measuring rods 11 can measure the bending angle of the steel plate more accurately. After the bending is completed, the angle between the two measuring rods 11 is the bending angle of the steel plate, thereby measuring the bending angle of the steel plate;

[0025] Then the lower pressing block 3 moves upward to take the bent steel plate out from between the lower pressing block 3 and the supporting block 4. At the same time, the first spring 8 and the second spring 17 respectively drive the angle plate 9 and the two measuring rods 11 to reset, so as to facilitate the next bending.

[0026] As a technical optimization solution of the utility model, the right side wall of the angle disk 9 is fixedly connected with a support plate 13 flush with the support block 4 and the measuring rod 11 , and the left side wall of the lower pressing block 3 is fixedly connected with a lower pressing rod 14 abutting against the support plate 13 .

[0035] In this embodiment, the telescopic rod 19 can enable the lower pressing block 3 to move smoothly.

[0036] As a technical optimization solution of the present invention, a scale line 20 is provided on the left side wall of the angle disk 9 .

[0037] In this embodiment, the scale line 20 facilitates intuitive observation of the bending angle of the steel plate.

[0038] Working principle: When in use, first move the steel plate between the lower pressing block 3 and the supporting block 4, so that the bending line of the steel plate is aligned with the bending groove 5, and at the same time, move the left side of the steel plate to the bottom of the baffle 12, and then adjust the position of the abutment plate 16 through the screw 15, so that the abutment plate 16 abuts against the steel plate, and then start the cylinder 18, which drives the lower pressing block 3 to move downward to bend the steel plate;

[0039] During the bending process, the lower pressing block 3 squeezes the bending line of the steel plate into the bending groove 5, so that the front and rear ends of the steel plate are tilted. When the steel plate is tilted, the steel plate cooperates with the baffle plate 12 to drive the two measuring rods 11 to rotate, and the bending angle of the steel plate is measured by the two measuring rods 11. At the same time, the lower pressing rod 14 cooperates with the support plate 13 to push the angle plate 9 to move downward. Since the support block 4 is flush with the support plate 13 and the measuring rod 11, the bending part of the steel plate can be continuously kept flush with the rotation point of the two measuring rods 11, so that the two measuring rods 11 can measure the bending angle of the steel plate more accurately. After the bending is completed, the angle between the two measuring rods 11 is the bending angle of the steel plate, thereby measuring the bending angle of the steel plate;

[0040] Then the lower pressing block 3 moves upward to take the bent steel plate out from between the lower pressing block 3 and the supporting block 4. At the same time, the first spring 8 and the second spring 17 respectively drive the angle plate 9 and the two measuring rods 11 to reset, so as to facilitate the next bending.
