[0014] Bearings are respectively provided at both ends of the upper pressure roller 412, and the support liner 408 and the locking block 410 are provided with limiting grooves for matching with the bearings.

[0015] The feeding device 2 includes a first hydraulic rod 201 installed on the upper end of the shell 1, an arc block is installed at the lower end of the first hydraulic rod 201, second hydraulic rods 202 are respectively arranged at both ends of the first hydraulic rod 201, and a pressing plate is installed at the lower end of the second hydraulic rod 202. A third hydraulic rod 203 is fixedly arranged at the upper end of the feeding end of the shell 1, and a roller is rotatably arranged at the lower end of the third hydraulic rod 203. A plurality of groups of rollers 204 used in conjunction with the rollers are installed inside the shell 1, and one end of one of the rollers 204 is connected to the output shaft of the third motor. A first lower die 205 and a second lower die 207 used in conjunction with the two second hydraulic rods 202 are arranged at the lower end of the shell 1, and an arc groove used in conjunction with the arc block is opened at the upper ends of the first lower die 205 and the second lower die 207. A fourth hydraulic rod 206 is respectively arranged at the lower ends of the first lower die 205 and the second lower die 207, and the first hydraulic rod 201, the fourth hydraulic rod 206, the third hydraulic rod 203 and the second hydraulic rod 202 are respectively connected to the hydraulic pump.

[0016] Working principle: When in use, the steel plate is placed on the upper end of the roller 204, the third hydraulic rod 203 is extended to press the steel plate, and then the output shaft of the third motor drives the roller 204 to rotate. When one side of the steel plate is located in the arc groove of the second lower die 207, the third motor stops working, and then the second hydraulic rod 202 close to the feeding end of the shell 1 is extended to press the steel plate, and the fourth hydraulic rod 206 at the lower end of the first lower die 205 is contracted, so that the fourth hydraulic rod 206 at the lower end of the second lower die 207 is extended, and then the first hydraulic rod 201 is extended, and the arc block at the lower end of the first hydraulic rod 201 cooperates with the arc groove of the second lower die 207 to bend the edge of the steel plate. After the bending is completed, the fourth hydraulic rod 206 at the lower end of the second lower die 207, the second hydraulic rod 202 and the first hydraulic rod 201 are contracted respectively; Then, the output shaft of the third motor drives the roller 204 to rotate, so that the steel plate enters between the lower pressure roller 305 and the upper pressure roller 412. Then, the first motor drives the rotating shaft 302 to rotate, and the worm section on the outer wall of the rotating shaft 302 drives the worm wheel 303 to rotate. The worm wheel 303 drives the first threaded rod 310 to rotate, and the first threaded rod 310 drives the threaded seat 304 to rise. At the same time, the first threaded rod 310 drives the active pulley 306 to rotate, and the active pulley 306 drives the driven pulley 403 to rotate through the synchronous belt. Since the second threaded rod 401 is threadedly connected to the driven pulley 403, at the same time, the second threaded rod 401 is threadedly connected to the driven pulley 403. The second threaded rod 401 is slidably connected to the mounting seat 404, and the mounting seat 404 is slidably connected to the second guide rod 3011, so the driven pulley 403 drives the second threaded rod 401 to move downward, thereby clamping the steel plate and bending it to form an arc, the first motor stops working, and then the output shaft of the fourth motor 311 drives the lower pressure roller 305 to rotate through the bevel gear set, and the lower pressure roller 305 drives the steel plate to move, so that the steel plate forms an arc, and then the first motor gradually drives the upper pressure roller 412 and the lower pressure roller 305 to approach each other, changing the arc of the steel plate so that the steel plate gradually forms a cylindrical shape; When the steel plate processing is completed, the first motor reverses, the lower pressure roller 305 moves downward, and drives the second threaded rod 401 to move upward, and the second threaded rod 401 drives the mounting seat 404 to move upward. When the mounting seat 404 moves to the upper end inside the shell 301, the mounting seat 404 cannot move further. At this time, the second threaded rod 401 continues to drive the mounting plate 406 to move upward, and the mounting plate 406 drives the support 408 to move upward through the connecting rod 407, so that the support 408 is located outside the shell 301. The upper end of the part, and at the same time, the mounting plate 406 drives one end of the locking block 410 upward through the first movable rod 409, and the other end of the locking block 410 is connected to the fixed rod 405 through the second movable rod 411, so that the locking block 410 will tilt to one side, thereby completely unlocking the lock on the upper pressure roller 412, and then facilitating the staff to use tools such as manipulators to take down the upper pressure roller 412 and the reel, place the reel and the upper pressure roller 412 on the ground, and then take out the upper pressure roller 412 inside the reel.

[0017] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
