[0028] As one embodiment in the present embodiment, as Figure 1 and Figure 4As shown, the inner top end of the bending machine body 1 is fixedly provided with a hydraulic rod 4, and the end of the hydraulic rod 4 away from the bending machine body 1 is provided with an upper die mechanism 5 for bending the plate, and the bottom end of the upper die mechanism 5 is correspondingly provided at the top end of the lower die mechanism 2. The upper die mechanism 5 comprises a gravity plate 501, the top end of which is fixedly provided at the bottom end of the hydraulic rod 4. The gravity plate 501 is made of a metal plate, and the bottom end of the gravity plate 501 is slidably provided with a bending knife 502 through a sliding groove. The bending knife 502 is fixedly connected to the gravity plate 501 through bolts. The worker holds the plate and places one end of the plate on the top of the bending table 202. At the same time, the worker pushes the plate to move on the top of the bending table 202, so that one end of the plate abuts against the front surface of the bending stop plate 308. According to the distance set between the bending stop plate 308 and the bending table 202, the size of the plate bending is limited. When the size of the plate bending is limited, the hydraulic rod 4 is started to drive the gravity plate 501 to move downward. The downward moving gravity plate 501 drives the bending knife 502 to continuously move downward. The continuously downward moving bending knife 502 extrudes the bending point of the plate until the bending knife 502 drives the plate to extrude into the bending groove 203, thereby bending the plate and realizing the function of bending multiple plates.

[0029] It should be noted that all electrical equipment in the device is controlled by the numerical control equipment of the bending machine body 1.

[0030] Working principle: when the plate needs to be bent, the worker first manually rotates the handle 309 to drive the lead screw 301 to rotate. The rotating lead screw 301 drives the sleeve seat 302 to move upward. The upward moving sleeve seat 302 drives the limiting sleeve 304 to move upward on the surface of the limiting rod 303 through the connecting plate 306. The upward moving sleeve seat 302 and the limiting sleeve 304 drive the two groups of air cylinders 307 to move upward through the connecting plate 306. The two groups of upward moving air cylinders 307 drive the bending stop plate 308 to move upward to the outside of the bending table 202. The front surface of the bending stop plate 308 is aligned with the side edge of the bending table 202. Then, the two groups of air cylinders 307 are simultaneously started to drive the bending stop plate 308 to adjust the distance between the bending stop plate 308 and the bending table 202 according to the size of the plate bending, so as to limit the size of the plate bending.

[0031] When the distance adjustment between the bending stop plate 308 and the bending table 202 is completed, the worker holds the plate and places one end of the plate on the top of the bending table 202, and at the same time, the worker pushes the plate to move on the top of the bending table 202, so that one end of the plate abuts against the front surface of the bending stop plate 308, and the size of the plate bending is limited according to the set distance between the bending stop plate 308 and the bending table 202, when the size of the plate bending is limited, the hydraulic rod 4 is started to drive the gravity plate 501 to move downward, the downward moving gravity plate 501 drives the bending knife 502 to continuously move downward, the continuously downward moving bending knife 502 extrudes the bending point of the plate, until the bending knife 502 drives the plate to extrude into the bending groove 203, thereby bending the plate, realizing the function of bending multiple plates.

[0032] In the process of plate bending, when the size of the plate bending needs to be adjusted, the bending size value set by the numerical control equipment of the bending machine body 1 controls the start of the two groups of cylinders 307, so that the two groups of cylinders 307 drive the bending stop plate 308 to adjust the distance between the bending stop plate 308 and the bending table 202 according to the size of the plate bending, realizing the function of automatic adjustment of the bending stop plate 308.

[0033] The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them.
