[0021] In this embodiment of the present invention, such as Figure 4 and Figure 5 As shown, the bottom of the first support plate 202 and the bottom of the third support plate 403 are both fixedly connected to the top of the workbench 1. The top of the workbench 1 has two limiting grooves 6, and a linkage frame 209 is slidably connected inside the limiting grooves 6. The linkage frame 209 serves to support and limit movement.

[0022] In this embodiment of the present invention, such as Figure 1 and Figure 6 As shown, a storage box 7 for placing rods 5 is fixedly connected above the workbench 1. An observation window 8 is provided on one side of the storage box 7. A feed hopper 9 is fixedly connected to the top of the storage box 7. The bottom of the push plate 307 is slidably connected to the bottom surface of the storage box 7. Push ports 10 adapted to the diameter of the rods 5 are provided on both sides of the storage box 7. A support frame 11 for supporting the storage box 7 is fixedly connected to the bottom of the storage box 7. The internal spacing of the storage box 7 is greater than the diameter of the rods 5, and only one rod 5 can be placed in its horizontal direction.

[0023] In this embodiment of the present invention, such as Figure 2 and Figure 6As shown, the bottom of the fixed plate 303 is fixedly connected to the top of the workbench 1. One end of the linkage rod 301 relative to the second insertion seat 308 passes through the fixed plate 303 and is fixedly connected to the drive sprocket 309. One end of the lead screw 304 passes through the fixed plate 303 and is fixedly connected to the driven sprocket 310. The drive sprocket 309 and the driven sprocket 310 are connected by a chain 311. A guide rod 312 is fixedly connected to one side of the fixed plate 303. The guide rod 312 slides through the push seat 305. Several support blocks 313 are fixedly connected to the periphery of the push rod 306. The support blocks 313 are equidistantly arranged. The support blocks 313 are used to support the rods 5 in the storage box 7. When one rod 5 is pushed out, the next rod 5 will not fall immediately to avoid preventing the push plate 307 from resetting.

[0024] The working principle of this embodiment is as follows: During operation, the rod 5 to be bent is first placed inside the storage box 7. The rod 5 is placed vertically inside the storage box 7, and only one rod 5 can be placed horizontally. Then, the electric push rod 211 is activated. The output end of the electric push rod 211 is fixedly connected to one side of the linkage frame 209. The linkage frame 209 is slidably connected inside the limiting groove 6 to limit the linkage frame 209. One end of the two inclined rods of the linkage frame 209 is fixedly connected to a collar 210. The periphery of the first insertion rod 204 and the periphery of the second insertion rod 205 are respectively rotatably connected to the inner wall of the collar 210. The output end of the electric push rod 211 extends, thereby driving the linkage frame 209 to move, which in turn drives the second insertion rod 205 to insert into the second insertion seat 308. The electric push rod 211 is then turned off. The first insertion rod 204 and the second insertion rod 205 have several slots 207 at one end opposite to the first support plate 202. The inner walls of the first insertion seat 410 and the second insertion seat 308 are both fixedly connected to locking blocks 208 that fit the slots 207. The locking blocks 208 slide in contact with the slots 207. Then, the servo motor 212 is started. The servo motor 212 rotates and drives the active bevel gear 213 fixedly connected to its output end to rotate. The active bevel gear 213 meshes with the driven bevel gear 214. The driven bevel gear 214 is fixedly connected to the circumferential side of the transmission rod 201. Therefore, the active bevel gear 213 rotates and drives the driven bevel gear 214 to rotate, thereby driving the transmission rod 201 to rotate. Several guide grooves 203 are provided at both ends of the transmission rod 201 to guide... The groove 203 is circumferentially arranged around the transmission rod 201. A first insert 204 and a second insert 205 are respectively fitted onto both ends of the transmission rod 201. The interiors of the first insert 204 and the second insert 205 are hollow. Slider 206, adapted to the guide groove 203, are fixedly connected to the inner walls of both the first insert 204 and the second insert 205. The slider 206 slides in contact with the guide groove 203. Therefore, the rotation of the transmission rod 201 drives the first insert 204 and the second insert 205 to rotate, which in turn drives the second insertion seat 308 to rotate. One end of the linkage rod 301 is fixedly connected to the second insertion seat 308, and the other end is fixedly connected to the drive sprocket 309. The drive sprocket 309 and the driven sprocket 310 are connected by a chain 311. Therefore, the second insertion seat 308 rotates... The movement of the linkage rod 301 causes the drive sprocket 309 to rotate, which in turn causes the driven sprocket 310 to rotate. The driven sprocket 310 is fixedly connected to the lead screw 304. The push seat 305 is threadedly connected to the lead screw 304. A push rod 306 is fixedly connected to the lower end of the push seat 305. A push plate 307 is fixedly connected to one end of the push rod 306. Therefore, the rotation of the driven sprocket 310 causes the lead screw 304 to rotate, which in turn causes the push seat 305 to move under the guidance of the guide rod 312. This, in turn, causes the push plate 307 to push the rod 5 out of the push port 10 on one side of the storage box 7. Several support blocks 313 are fixedly connected to the periphery of the push rod 306. When one rod 5 is pushed out, the next rod 5 will not fall immediately to avoid preventing the push plate 307 from resetting.At this time, the openings of the first bending member 406 and the second bending member 407 are in a horizontal straight line, allowing the rod 5 to be smoothly pushed into the first bending member 406 and the second bending member 407. Then, the servo motor 212 rotates in the reverse direction, causing the pusher assembly 3 to reset. Then, the servo motor 212 is turned off, and the electric push rod 211 is started again. The output end of the electric push rod 211 retracts, thereby driving the first insertion rod 204 to insert into the first insertion seat 410. The electric push rod 211 is turned off, and the servo motor 212 is started again, causing the first insertion seat 410 to rotate. Because one end of the second worm 402 is fixedly connected to the first insertion seat 410, the first worm wheel 408 is fixedly connected to the circumference of the first rotating rod 404, and the second worm wheel 409 is fixedly connected to the circumference of the second rotating rod 405. The first worm 401 meshes with the first worm wheel 408, and the second worm 402 meshes with the second worm wheel 409. One end of the first worm 401 is fixedly connected to one end of the second worm 402, and their threads are arranged in opposite directions. Therefore, the first insertion seat 410 rotates and drives the first worm 401 and the second worm 402 to rotate, thereby driving the first worm wheel 408 and the second worm wheel 409 to rotate, and in turn driving the first rotating rod 404 and the second rotating rod 405 to rotate. One end of the first worm 401 and one end of the second worm 402 are fixedly connected, and their threads are arranged in opposite directions. Therefore, the first bending member 406 and the second bending member 407, which are fixedly connected to the top ends of the first rotating rod 404 and the second rotating rod 405, rotate in opposite directions, so that the periphery of the rod 5 is subjected to pressure, and the middle of the rod 5 is deformed. The bending angle can be controlled according to the rotation angle of the servo motor 212. After the bending is completed, the rod 5 is removed. Then, the servo motor 212 and the electric push rod 211 continue to start, so that the bending assembly 4 and the transmission assembly 2 are reset. The bending operation is repeated in this way.
