[0028] As Figures 1 to 4 shown, the flexible bending system for copper bar processing includes:

[0029] A base 3 and a bending mechanism. A conveying platform 1 is arranged on the base 3, and a feeding mechanism and a storage box 2 are arranged on the conveying platform 1;

[0030] Among them, the height of the output end of the storage box 2 is greater than the thickness of a group of copper bars and less than the sum of the thicknesses of two groups of copper bars; the feeding mechanism is used to convey the copper bar blanks stored in the storage box 2 to the processing position of the bending mechanism one by one, and use the bending mechanism to bend the copper bar blanks.

[0031] The conveying platform 1 is installed on the base 3 for placing copper bars, and has an installation cavity inside. The cavity is located in the middle, and the bending area side and the top are set as openings, and the opening size is smaller than the length of the copper bar;

[0032] The storage box 2 is installed on the conveying platform 1. There is a discharge port on one side of the bottom end. The width of the discharge port is greater than the thickness of a group of copper bars and less than the sum of the thicknesses of two groups of copper bars. A through groove is arranged at the symmetric end of the discharge port, and the position of the through groove corresponds to the position of the opening. The top end is set as an inclined structure on the side of the through groove, and an inclined notch is arranged at the input end of the storage box 2;

[0033] The feeding mechanism is used to convey the copper bars inside the storage box 2 one by one;

[0034] The bending mechanism is used to bend the copper bars pushed out of the storage box 2 by the feeding mechanism;

[0035] During use, the conveying platform 1 is used for placing the stacked copper bars and can provide a rotating platform for conveying the copper bars to the bending area. The cavity of the conveying platform 1 is used for installing the feeding mechanism, and the opening enables the working end to convey the copper bars. The storage box 2 is used for stacking and positioning multiple groups of copper bars. The width of the discharge port is set to be greater than the thickness of one group of copper bars and less than the sum of the thicknesses of two groups of copper bars, ensuring that only the bottommost group of copper bars is conveyed during feeding. An inclined mechanism is provided at the bottom of the storage box 2 to facilitate the addition of copper bars into the storage box 2 and reduce the difficulty of observing the remaining amount of copper bars. The feeding mechanism is used to convey the copper bars at the bottommost part inside the storage box 2 to the bending mechanism, and the bending mechanism is used to bend the copper bars.

[0036] As a preference of the above embodiment, the feeding mechanism includes a power component and a transmission component 4. The transmission component 4 further includes a push plate 6 that can extend into the bottom of the storage box. The height of the push plate 6 extending into the storage box 2 is less than the thickness of one group of copper bar blanks. A through hole for the push plate 6 to pass through is provided at one end of the storage box 2 away from the bending mechanism. The power component is used to drive the push plate 6 to move reciprocally.

[0037] The feeding mechanism includes a transmission component 4 installed in the inner cavity of the conveying platform 1. The transmission component 4 is slidably connected to the two side walls of the cavity of the conveying platform 1. An extension end is provided on the transmission component 4. A baffle is provided on one side of the extension end, and the baffle is on the non-bending mechanism side. A support shaft 5 is installed on the extension end, and a push plate 6 is installed on the support shaft 5. The working end of the push plate 6 passes through the opening of the conveying platform 1. One side of the push plate 6 is in contact connection with the baffle. Inner grooves are respectively provided at both ends of the push plate 6 coaxially installed with the support shaft 5, and a coil spring 7 is installed in the inner groove. The other end of the coil spring 7 is connected to the support shaft 5. The dimension of the push plate 6 above the top surface of the conveying platform 1 is less than the thickness of one group of copper bars.

[0038] The push plate 6 is installed on the transmission component 4 by means of an elastic member. The push plate 6 can rotate a certain angle in the direction of the bending mechanism under the action of an external force and return to the vertical state without the action of an external force.

[0039] During the feeding process, the push plate 6 always maintains a vertical state. When the feeding is completed and the return journey starts, under the displacement restriction of the bottommost copper bar blank in the storage box 2, the push plate 6 remains in an inclined state and is completely below the bottommost copper bar blank until the push plate 6 completely disengages from the bottommost copper bar blank in the storage box 2.

[0040] The elastic member includes a support shaft 5 provided on the transmission component 4 and a coil spring 7 sleeved on the support shaft 5. The push plate 5 is rotatably installed on the support shaft 5 by means of the coil spring 7. The rotation axis of the push plate 6 is perpendicular to the reciprocating movement route of the push plate 6.

[0041] A limiting member is provided on the transmission component, and the limiting member is used to keep the push plate vertical without the action of an external force.

[0042] The pushing plate 6 is vertically and fixedly installed on the transmission component 4. One end of the pushing plate 6 close to the bending mechanism is perpendicular to the copper bar blank. An inclined surface is provided at one end of the pushing plate 6 away from the bending mechanism, and the bottom line of the inclined surface is always located below the copper bar blank at the bottommost end of the storage bin 2;

[0043] An arc chamfer is provided at the top line of the inclined surface;

[0044] During use, the support shaft 5 is used to rotatably support the pushing plate 6 on the transmission component 4. The baffle plate plays a role in limiting the rotation angle of the pushing plate 6. When the transmission component 4 drives the pushing plate 6 to displace, the pushing plate 6 feeds the copper bar at the bottom end inside the storage bin 2 through the limit of the baffle plate. It should be noted that the dimension of the end of the pushing plate 6 higher than the top surface of the conveying platform 1 is smaller than the thickness of a group of copper bars, ensuring that when the transmission component 4 moves, the pushing plate 6 only applies a driving force to a group of copper bars at the bottommost end of the storage bin 2. The pushing plate 6 is rotatably installed with the transmission component 4 to prevent pushing the copper bars inside the storage bin 2 during reset by flipping. The coil spring 7 is used to provide a reset power after the relative rotation of the pushing plate 6 and the support shaft 5, ensuring that the pushing plate 6 can feed again.

[0045] As a preference of the above embodiment, the bending mechanism includes a fixed component 8 installed on the base 3. A fixed die set 9 is installed in the cavity of the fixed component 8. A boss structure is provided in the middle of the fixed die set 9. The top side end face of the conveying platform 1 and the boss end face of the fixed die set 9 are in the same plane. A cylinder 10 is installed on the other side of the cavity of the fixed component 8. A moving die set 11 is installed at the output end of the cylinder 10. A groove is provided in the middle of the moving die set 11. The boss of the fixed die set 9 and the groove of the moving die set 11 are arranged in corresponding positions. The length of the convex groove of the fixed die set 9 is the same as the bending dimensions at both ends of the copper bar;

[0046] During use, the fixed component 8 is used to position and install the fixed die set 9 and the cylinder 10. The cylinder 10 is used to drive the lifting of the moving die set 11. The cooperation between the groove of the moving die set 11 and the boss of the fixed die set 9 enables the two sides of the copper bar to be bent synchronously to ensure the bending efficiency. The top side end face of the conveying platform 1 and the boss end face of the fixed die set 9 being in the same plane enables the smooth conveying of the copper bar. It should be pointed out here that when the bent copper bar is on the boss of the fixed die set 9, when the copper bar at one end of the next storage bin 2 is fed, the bent copper bar can be pushed away from the boss of the fixed die set 9. This structure saves the taking process, and the simultaneous bending on both sides has higher efficiency compared to the low efficiency of adjusting the position after single-side bending and then performing the bending process on the other side.

[0047] As a preference of the above embodiment, the reciprocating lead screw nut pair includes a lead screw 12 installed inside the cavity of the conveying platform 1. The lead screw 12 is cooperatively connected with the transmission component 4. A storage groove is provided on the fixed component 8, and the other end of the lead screw 12 is connected to the wall of the storage groove of the fixed component 8;

[0048] During use, the lead screw 12 is threadedly connected to the transmission component 4 when rotating to drive the working position of the pushing plate 6 to be adjusted, so as to keep the pushing plate 6 moving smoothly during the copper bar feeding and return trips.

[0049] As a preference of the above embodiment, the power component adopts a reciprocating lead screw nut pair;

[0050] The power component includes a servo motor 13 installed inside the cavity of the conveying platform 1. A gear 14 is coaxially installed on the output end of the servo motor 13 and the lead screw 12. The two groups of gears 14 are connected in cooperation. When the cylinder 10 drives the moving module 11 to cooperate with the fixed component 8 for bending, it is in the process of the servo motor 13 driving the pushing plate 6 to return.

[0051] During use, the two groups of gears 14 mesh to make the lead screw 12 cooperate with the output end of the servo motor 13 for transmission. The servo motor 13 is used to provide rotational power for the lead screw 12. It should be noted here that the servo motor 13 starts to rotate reversely at the set feeding start end and end of the pushing plate 6. This setting keeps the pushing plate 6 performing continuous reciprocating feeding.

[0052] As a preference of the above embodiment, guide posts 15 are symmetrically arranged at both ends of the fixed component 8. Through holes are provided at the corresponding positions of the moving module 11 for the guide posts 15, and the moving module 11 is connected to the through holes of the guide posts 15.

[0053] During use, the guide posts 15 are used to limit and guide the relative movement trajectories of the moving module 11 and the fixed module 9, so as to ensure the bending accuracy of the copper bar when the moving module 11 and the fixed module 9 cooperate.

[0054] As a preference of the above embodiment, a stepped groove is provided on one side of the base 3. A collection box 16 is placed at the stepped groove of the base 3, and the collection box 16 is lower than the installation height of the fixed module 9;

[0055] During use, the collection box 16 is used to centrally collect the bent copper bars. The collection box 16 is set to be lower than the installation height of the fixed module 9 so that the bent copper bars can freely fall under the action of gravity.

[0056] As a preference of the above embodiment, multiple groups of leveling components 17 are installed at the bottom end of the base 3;

[0057] During use, the multiple groups of leveling components 17 cooperate to stably support the base 3, which is convenient for the support and leveling of the base 3.

[0058] When the device operates, first stack the copper bars neatly and place them inside the storage box 2. Then start the servo motor 13, and drive the lead screw 12 to rotate through the meshing of two groups of gears 14. Then, the lead screw 12 is in threaded cooperation with the transmission component 4 to drive the push plate 6 to move. When the push plate 6 contacts the copper bar at the bottom of the storage box 2, the push plate 6 pushes the copper bar through the limit of the baffle partition. At the same time, the upper copper bars are centrally blocked through the discharge port of the storage box 2. Then the copper bars are conveyed to the convex platform of the fixed die set 9. Then the servo motor 13 rotates in the reverse direction to drive the push plate 6 to return. When the push plate 6 contacts the copper bar at the bottom of the storage box 2, the push plate 6 rotates relative to the support shaft 5 due to the resistance. When the push plate 6 is separated from the contact with the copper bar, the push plate 6 flips and resets under the action of the coil spring 7 and contacts the baffle partition again. And during the return process of the push plate 6, the cylinder 10 is started, and the copper bar is bent through the cooperation of the moving die set 11 and the fixed die set 9. When the push plate 6 conveys the next group of copper bars again, when the copper bar contacts the bent copper bar, the bent copper bar is pushed away from the convex platform of the fixed die set 9, and under the action of gravity, the bent copper bar falls into the collection box 16 for centralized collection.

[0059] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
