[0021] like Figures 1-4 As shown, the present invention discloses a triangular aluminum hoop forming device for pencils, comprising a frame 1, a vibrating feeder 2, a pushing mechanism 3, a triangular forming mold 4, a pneumatic three-jaw chuck 5, and a demolding mechanism. The vibrating feeder 2 for conveying aluminum hoops is mounted on the frame 1. The pushing mechanism 3 is provided on one side of the end of the discharge track 21 of the vibrating feeder 2 for pushing the aluminum hoop into the triangular forming mold 4. The center of the triangular forming mold 4 is provided with a triangular cavity. The pneumatic three-jaw chuck 5 is provided at the opposite position of the triangular forming mold 4 for clamping the aluminum hoop and forming it into a triangular aluminum hoop. The demolding mechanism includes a demolding component 6 for driving the pneumatic three-jaw chuck 5 to move the formed triangular aluminum hoop backward, and a stop tip 8 fixed on the mounting plate 11 of the frame 1 for blocking the triangular aluminum hoop when the pneumatic three-jaw chuck 5 moves backward, so that it falls off the pneumatic three-jaw chuck 5.

[0022] The pushing mechanism 3 includes a first cylinder 31, a first push plate 32, a first push rod 33, a first movable seat 34, and a push head 35. The first cylinder 31 is mounted on the frame 1. The piston rod of the first cylinder 31 faces the end of the discharge track 21 and is connected to one side of the first push plate 32. One end of the first push rod 33 is connected to the other side of the first push plate 32, and the other end of the first push rod 33 is connected to one side of the first movable seat 34. The push head 35 is mounted on the other side of the first movable seat 34, and the push head 35 faces the outlet of the discharge track 21.

[0023] A first slide rail 7 is installed on the mounting plate 11 below the first movable seat 34. The bottom of the first movable seat 34 is provided with a slider for sliding connection with the first slide rail 7 to ensure smooth linear motion during the pushing process.

[0024] The triangular cavity on the triangular forming mold 4 is aligned with the outlet of the discharge track 21 and the axis of the pneumatic three-jaw chuck 5.

[0025] The demolding assembly 6 includes a second cylinder 61, a second push plate 62, and a second push rod 63. The second cylinder 61 is mounted on the frame 1. The piston rod of the second cylinder 61 faces the end of the discharge track 21 and is connected to one side of the second push plate 62. One end of the second push rod 63 is connected to the other side of the second push plate 62, and the other end of the second push rod 63 is connected to one side of the second movable seat 51. The pneumatic three-jaw chuck 5 is mounted on the other side of the second movable seat 51.

[0026] A second slide rail 9 is mounted on the mounting plate 11 below the second movable seat 51. The bottom of the second movable seat 51 is provided with a slider for sliding connection with the second slide rail 9, thereby driving the pneumatic three-jaw chuck 5 to move back and forth stably.

[0028] The stop tip 8 is fixed to the mounting plate 11 by a bracket, and the tip of the stop tip 8 faces the pneumatic three-jaw chuck 5.

[0029] Working principle: The vibrating feeder 2 sorts and conveys the aluminum hoops to the end of the discharge track 21. The first cylinder 31 pushes the first push plate 32, which, through the first push rod 33, causes the first moving seat 34 to slide along the first slide rail 7, driving the push head 35 to push the aluminum hoop into the triangular cavity of the triangular forming mold 4. Subsequently, the pneumatic three-jaw chuck 5 actuates, and its three jaws 52 contract synchronously, extruding the aluminum hoop into a triangular aluminum hoop within the mold cavity. After forming, the jaws loosen slightly, and the second cylinder 61 of the demolding assembly 6 actuates, pushing the second moving seat 51 backward along the second slide rail 9 through the second push plate 62 and the second push rod 63, thereby causing the pneumatic three-jaw chuck 5 and the triangular aluminum hoop fitted on it to retract together. The fixed stop tip 8 blocks the triangular aluminum hoop on the retraction path, causing the triangular aluminum hoop to be scraped off the jaws and enter the discharge chute through the discharge port 111, completing the demolding. Then, all components reset and the cycle repeats.
