It is mainly suitable for the manufacture of large metal parts related to aerospace. Its characteristics are no mold, low manufacturing cost, high forming efficiency, dense formed parts, short processing cycle, and only a small amount of machining is required for the final formed parts.

[0031] See also Figure 1-Figure 4 As shown in the figure, a wire feeding device for arc additive and subtractive material production includes a robot arm 200, a base 100 is arranged at the bottom of the robot arm 200, an inductor 400 is arranged on the surface of one end of the robot arm 200 away from the bottom, and a welding gun 300 is fixedly connected to the bottom of the inductor 400;
[0032] A wire feeding device 500 is provided on the surface of the welding gun 300, and the wire feeding device 500 includes a limiting ring 502, one end of the limiting ring 502 is fixedly connected to the surface of the welding gun 300, and the other end passes through and is fixedly connected to a positioning tube 503, a starting block 501 is fixedly connected to the top of the limiting ring 502, and a welding wire 510 passes through and is slidably connected inside the starting block 501, one end surface of the welding wire 510 is slidably connected to the inner wall of the positioning tube 503, and the other end surface of the welding wire 510 is wound around the surface of a rotating rod 509, and the welding wire 510 is used to maintain a stable positioning during wire feeding. At the same time, in order to provide a certain tension and guidance during wire feeding and ensure that the welding wire 510 can maintain an appropriate position and angle when entering the welding gun 300, a rotating wheel 507 is provided on the surface of the side of the welding wire 510 close to the sensor 400, and a wire 504 is provided between the sensor 400 and the starting block 501, and the two ends of the wire 504 are respectively fixedly connected to the sensor 400 and the starting block The surface of 501 can transmit signals or electricity so that the sensor 400 can detect a certain condition or state and transmit relevant information to the start block 501, thereby triggering the corresponding operation or function. The fixed connection of the wire 504 can ensure the stable transmission of signals or electricity, while ensuring the reliability and stability of the system. The two sides of the rotating wheel 507 are fixedly connected with disks 506, and the opposite surfaces of the disks 506 are both in contact with the surface of the welding wire 510. The bottom surface of the robot arm 200 is fixedly connected with a circular sleeve 508, and the central surface of the robot arm 200 is fixedly connected with an L-shaped sleeve 511. The surface of the welding wire 510 is slidably connected to the inner wall of the L-shaped sleeve 511, which helps to ensure that the robot arm 200 maintains a fixed position and direction during operation, so as to help support the middle of the welding wire 510 to prevent the welding wire 510 from being pulled too long and affecting the operation of the robot arm 200. The internal rotation of the circular sleeve 508 is connected with a rotating rod 509.
[0033] When in use, when a person starts the equipment through an external power source, the robot arm 200 first drives the welding gun 300 to move to the position of the material, and then the welding gun 300 starts to spray flames, and at the same time, the wheel 507 in the start block 501 rotates, driving the welding wire 510 on its surface to move downward. Here, when the welding gun 300 is ignited by the robot arm 200, the sensor 400 between the start block 501 and the start block 501 sends a signal using the wire 504, and the disc 506 on the left and right sides of the wheel 507 is used to rotate. A limit is placed on the welding wire 510 to ensure stability during wire feeding. The welding wire 510 is fed into the bottom of the welding gun 300 through the positioning tube 503 at the bottom for operation. At the same time, the other end of the welding wire 300 is wound around the rotating rod 509 in the circular sleeve 508 of the robot arm 200. At the same time, an L-shaped sheath 511 is used in the center table of the robot arm 200.

[0034] At the same time, in order to prevent the welding wire from shifting when the robot arm moves, please refer to Figure 1-Figure 4 As shown in the figure, a wire-pulling device 600 is provided on the surface of the welding wire 510, and the wire-pulling device 600 includes an electric telescopic rod 601, and the surface of the electric telescopic rod 601 is fixedly connected to the inner wall of the starting block 501, and the output end of the electric telescopic rod 601 is fixedly connected to a rubber sleeve 602, and the top of the rubber sleeve 602 is fixedly connected to a support plate 603, and the front end of the support plate 603 is provided with an arc plate 604, and the bottom of the arc plate 604 is fixedly connected to the top surface of the starting block 501, and the arc plate 604, the support plate 603 and the rubber sleeve 602 are all attached to the welding wire 510, and the fixed connection is used to ensure a firm combination between them, providing additional support and structural strength for the system, indicating that the arc plate 604, the support plate 603 and the rubber sleeve 602 are all tightly attached to the welding wire 510 to prevent the welding wire 510 from friction or unnecessary vibration during movement.
[0035] During use, after the welding wire 510 stops feeding, the electric telescopic rod 601 fixed on the other side of the starting block 501 is first extended, pushing the rubber sleeve 602 on the surface of its output end, and at the same time driving the support plate 603 on the top of the rubber sleeve 602 to fit toward the welding wire 510, and at the same time approaching the arc plate 604 on the top of the starting block 501, to simply fix the welding wire 510, to prevent the welding wire 510 from forming a range of activities of the robotic arm 200 due to the lack of designated positioning when the robotic arm 200 moves significantly after welding is completed.
