[0025] The bending mechanism includes a rib plate group 22, which is slidably connected to the support seat 21, one side of the rib plate group 22 is fixedly connected to the first telescopic member 221, the first telescopic member 221 is fixedly connected to the support seat 21, the first telescopic member 221 can drive the rib plate group 22 to move on the support seat 21, the other side of the rib plate group 22 is provided with a support plate guide rail 25, the support plate guide rail 25 is slidably connected to the support plate 23, a bending roller 24 is provided on the side of the support plate 23 away from the support plate guide rail 25, one side of the support plate 23 is fixedly connected to the output shaft 232 of the second telescopic member 231, the second telescopic member 231 is fixedly connected to the rib plate group 22, the second telescopic member 231 can drive the support plate 23 and the bending roller 24 to move up and down along the support plate guide rail 25.

[0026] The two ends of the upper mold 31 are fixed on the fixed seat 35, and a buffer assembly is provided in the fixed seat 35. The top of the fixed seat 35 is fixedly connected to the third telescopic member 34, and the third telescopic member 34 is fixedly connected to the support seat 21. The third telescopic member 34 can drive the upper mold 31 to move up and down. The buffer assembly includes a buffer cavity 351 opened inside the fixed seat 35, and a buffer plate 374 is provided in the buffer cavity 351. A spring 375 is provided on the upper part of the buffer plate 374, and a guide plate 371 is provided on the lower part of the buffer plate 374. After the guide plate 371 extends out of the bottom of the fixed seat 35, both ends of the guide plate 371 are fixedly connected to fixed ears 373. The upper mold 31 is limited between the two fixed ears 373, and the bottom of the fixed seat 35 is provided with a clearance space 353 that allows the fixed ears 373 to move up and down. When the third telescopic member 34 can drive the upper mold 31 to move downward, the upper mold 31 presses the lower mold 33, and the fixed ear 373 drives the guide plate 371 to press the buffer plate 374 to move upward, thereby compressing the spring 375 until the fixed ear 373 is restricted by the clearance space 353, and then the upper mold 31 and the lower mold 33 are pressed together to bend the plate. On the one hand, this buffering process can pre-position the position of the plate to ensure the accuracy of the plate placement position, and on the other hand, it can prevent the upper mold 31 from directly colliding and squeezing the lower mold 33 to cause marks on the workpiece.

[0027] Furthermore, in order to better align the upper mold 31 and the lower mold 33 , guide blocks 372 are provided on both sides of the guide plate 371 , and the fixing seat 351 is provided with guide grooves 352 cooperating with the guide blocks 372 .

[0028] The lower mold 33 is fixed on the support base 21 and is disposed vertically corresponding to the upper mold 31 .

[0029] At least two different molds are evenly arranged around the outer circumference of the upper mold 31 and the lower mold 33, which can bend the plate into various shapes. One end of the upper mold 31 and the lower mold 33 are fixed to the servo motor 32, and the servo motor 32 is fixed to the fixed ear 373. The servo motor 32 can control the rotation of the upper mold 31 and the lower mold 33 to convert the molds, and each rotation of the servo motor 32 will make the upper mold 31 and the lower mold 33 on the two support seats 21 correspond.

[0030] Furthermore, in the present invention, four different molds are evenly arranged around the outer circumference of the upper mold 31 and the lower mold 33, which can bend the plate into four shapes. Those skilled in the art can also select a suitable number of molds according to needs.

[0031] Preferably, the first telescopic member 221, the second telescopic member 231 and the third telescopic member 34 are all cylinders. The cylinder is a prior art and its working principle is not described in detail. Those skilled in the art can also select a suitable telescopic member according to needs.

[0032] The working principle of the present invention is as follows:

[0033] The support seat driving member 211 drives the two support seats 21 to move toward or oppositely, and can adjust the distance between the upper mold 31 and the lower mold 33 located on the two support seats 21. The first telescopic member 221 can drive the rib plate group 22 to move left and right on the support seat 21, so that the bending mechanism fixed on the rib plate group 22 can adapt to the bending of plates of different sizes. When the positions of the bending mechanism and the two support seats 21 are adjusted, the plate is placed between the upper mold 31 and the lower mold 33. When the third telescopic member 34 can drive the upper mold 31 to move downward, the upper mold 31 presses the lower mold 33, and the fixed ear 373 drives the guide plate 371 to press the buffer plate 374 to move upward, thereby compressing the spring 375 until the fixed ear 373 is limited by the clearance space 353, and then the upper mold 31 and the lower mold 33 are pressed together, and the second telescopic member 231 drives the support plate 23 and the bending roller 24 to move downward along the support plate guide rail 25 to bend both sides of the plate. The buffering process of the spring 375 can, on the one hand, pre-position the plate to ensure the accuracy of the plate placement position, and on the other hand, prevent the upper mold 31 from directly colliding and squeezing the lower mold 33 to cause marks on the workpiece. When the mold needs to be replaced, the servo motor 32 can control the rotation of the upper mold 31 and the lower mold 33 to convert the mold, and each rotation of the four servo motors 32 will make the upper mold 31 on the two support seats 21 correspond to the lower mold 33.

[0034] In summary, by setting up the buffer component, the present invention can, on the one hand, pre-position the position of the plate to ensure the accuracy of the plate placement position, and on the other hand, prevent the upper die from directly colliding and squeezing with the lower die, causing imprints on the workpiece. By evenly surrounding and arranging at least two different and rotatable dies on the outer peripheries of the upper die and the lower die, the dies can be quickly replaced, and the plate can be bent into various shapes, improving the working efficiency and applicability of the bending machine. The beneficial effects of the present invention are as follows: it can pre-position the position of the plate to ensure the accuracy of the plate placement position, it can prevent the upper die from directly colliding and squeezing with the lower die, causing imprints on the workpiece, it can quickly replace the die, and it improves the working efficiency and applicability of the bending machine.
