[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 4 In an embodiment of the present invention, a bending device for producing an automobile component skeleton includes a mounting cover box 1, a feed plate 3 is fixedly connected to one side of the top of the mounting cover box 1, a feed guide groove is provided in the middle of the feed plate 3, and the inner cavity width of the feed guide groove is slightly larger than the width of the bending material. In this embodiment, the bending material is a metal pipe, and the metal pipe is cut to a fixed length before the bending operation. A feed hopper 2 is fixedly connected to the top of the feed plate 3, and the top of the feed hopper 2 is open;

[0022] A bending workbench 4 is fixedly connected to the middle of the inner wall of the mounting cover box 1, and a bending discharge chute 12 is provided at one end of the top of the bending workbench 4. The width of the bending discharge chute 12 is greater than the width of the metal pipe, and the shape of the bending discharge chute 12 is consistent with the shape of the bent finished product, so that the metal pipe can fall from the bending discharge chute 12 after bending.

[0023] One side of the bending and unloading trough 12 is fixedly connected with a bending limit plate 11, and the shape of the bending limit plate 11 is consistent with the shape of the bending and unloading trough 12. A plurality of bending grooves are provided on the other side of the bending and unloading trough 12, and a plurality of pushing blocks 5 are slidably connected inside the plurality of bending grooves, and a plurality of pushing rods 6 are fixedly connected to the tops of the plurality of pushing blocks 5, and a plurality of docking blocks are fixedly connected to the bottoms of the plurality of pushing blocks 5. One end of the installation cover box 1 is fixedly connected with a support frame, and a plurality of bending hydraulic cylinders 7 are fixedly installed on the top of the support frame, and the output ends of the plurality of bending hydraulic cylinders 7 are respectively fixedly connected to the bottoms of the plurality of docking blocks; the pushing blocks 5 and the pushing rods 6 are driven by the bending hydraulic cylinders 7 to move, so as to bend the metal pipe. In the specific implementation, the pushing rods 6 with different shapes can be replaced according to the specific shape requirements of the bending, so as to obtain bent products of different shapes during the pushing and bending, and the corresponding shapes of the bending and unloading trough 12 and the bending limit plate 11 are consistent with the bent products;

[0024] In order to improve the stability of the position of the metal tube during the push-bending process and prevent it from longitudinally turning over and warping, the top of the push rod 6 is fixedly connected to a limiting pressure plate 21, and the top surface height of the limiting pressure plate 21 is less than the top surface height of the bending limiting plate 11. The limiting pressure plate 21 is used to press and limit the metal tube to ensure a stable bending operation of the metal tube.

[0025] In order to realize the acceptance of the bent raw materials and the limitation of their ends, docking chutes 10 are provided on both sides of the top of the bending workbench 4. The inner walls of the two docking chutes 10 are slidably connected with a material receiving seat 9. The top of the material receiving seat 9 is rotatably connected with a connecting column through a torsion spring. The top of the connecting column is fixedly connected with an electric clamp 8. A return spring is fixedly connected between one side of the material receiving seat 9 and the inner wall of the docking chute 10. One end of the docking chute 10 extends to the bottom of the feed guide groove. The feed guide groove is fixedly connected to the feed guide groove through the electric clamp 8. The two ends of the metal pipe inserted are limited to facilitate the pushing and bending operation. The length of the docking chute 10 is less than the length of the bending groove, that is, a certain distance is left between the end of the docking chute 10 and the bending limit plate 11, so as to avoid the electric clamping jaws 8 and other structures from affecting the bending and fitting operation of the metal pipe and the bending limit plate 11. When the material receiving seat 9 moves to the end of the docking chute 10, the pushing rod 6 can still push the metal pipe to move and facilitate the separation of the metal pipe and the electric clamping jaw 8.

[0026] A diversion mechanism is fixedly connected to one side of the feed plate 3, and the diversion mechanism includes a side cover plate 19, and a driving motor 16 is fixedly installed on the inner wall of the side cover plate 19. A driving rod 15 is fixedly connected to the output end of the driving motor 16, and a plurality of equally spaced diversion sleeves 13 are fixedly connected to the middle part of the driving rod 15. A plurality of equally angled diversion baffles 14 are fixedly connected to the outer wall of the diversion sleeve 13. The gap between any two adjacent diversion baffles 14 can only accommodate one metal pipe. A through opening is opened at a position corresponding to the plurality of diversion sleeves 13 on one side of the feed guide groove. The size of the through opening is sufficient to allow the diversion baffle 14 to rotate and pass through. Through the driving motor 16 and other structures, a plurality of diversion turntables are driven to rotate, and the gaps between the plurality of diversion turntables are utilized to divert and guide the fed metal pipes one by one, so that the bending operation can be carried out in an orderly and continuous manner.

[0027] In order to realize the orderly and automatic delivery of the bent parts, a discharge rack is fixedly installed at the bottom of the inner wall of the installation cover box 1, and a discharge conveyor belt 18 is rotatably installed on the inner wall of the discharge rack. A discharge port is opened at the end of the installation cover box 1 away from the bending hydraulic cylinder 7, and one end of the discharge conveyor belt 18 extends into the discharge port.

[0028] In order to perform dust-proof operation on the bending workbench 4, a dust-proof cover 17 is installed on the center of the top of the cover box 1, and both sides of the top of the dust-proof cover 17 are fixedly connected with lifting handles. The dust-proof cover 17 is made of transparent material. When necessary, the dust-proof cover 17 can be opened by pulling the handles to repair and adjust the mechanism components on the bending workbench 4.

[0029] In order to realize automatic feeding of the bending raw materials, a feed rack is fixedly connected to one side of the feed hopper 2, and a feed conveyor belt 20 is rotatably installed on the inner wall of the feed rack. The top surface height of the feed conveyor belt 20 is less than the top height of the feed hopper 2.

[0030] The working principle of the present invention is to arrange the bending materials cut into fixed lengths on the feed conveyor belt 20 at equal intervals, and make the length direction of the bending materials consistent with the width direction of the feed conveyor belt 20, and feed a number of bending materials into the feed hopper 2 through the conveyance of the feed conveyor belt 20, and then the bending materials descend along the feed hopper 2 and enter the feed guide groove in a single-row arrangement, and the driving motor 16 drives the driving rod 15 to rotate, thereby driving a number of diversion sleeves 13 to rotate, and then driving the diversion baffle 14 to rotate, so that the bending materials fall;

[0031] The two ends of the bending material are supported and fixed by two electric clamps 8, and then the bending hydraulic cylinder 7 is started, driving a number of push blocks 5 and push rods 6 to move and push the bending material to move and bend. The bending material drives the electric clamps 8 and the material receiving seat 9 on both sides to slide along the docking chute 10. When the material receiving seat 9 moves to one end of the docking chute 10 close to the bending limit plate 11, the traction of the bending material will drive the connecting column to rotate, and then the electric clamps 8 are released, so that the bending material can be separated from the electric clamps 8 under the push of the push rod 6, and fit into contact with the push limit plate to complete the bending operation of the bending material, and the material receiving seat 9 is reset under the push of the reset spring; then the bending hydraulic cylinder 7 is reset, and the bent product obtained by bending the bending material falls from the bending discharge chute 12 to the discharge conveyor belt 18, and then the discharge conveyor belt 18 rotates to send the bent product out from the discharge port.
