[0002] In daily life, cars are the most common means of transportation. During driving, tire blowouts are one of the biggest safety hazards. Equipping cars with tire blowout emergency safety devices is essential. These devices are made of modified polymer materials and are ring-shaped devices installed inside the wheel. By filling the grooves in the wheel rim, the device allows the wheel rim to press tightly against the tire belly after a tire blowout, increasing friction and enabling the vehicle to achieve better handling, stability, and safety. Therefore, the manufacturing process is very important, and the use of a bending machine is also necessary during the arc bending process.

[0003] For example, patent document CN210553964U discloses a tire blowout emergency safety device, which specifically includes two support belts, a connecting component connected to the two support belts, and a pad bead disposed on the support belts. The support belts have mounting holes for inserting the pad bead, and the support belts have protruding flanges that surround the pad bead. The pad bead has a first end face and a second end face, and the first end face of the pad bead is provided with a first anti-slip structure for contacting the wheel rim. However, this prior art still has many shortcomings. For example, the emergency safety device is prone to bending position deviation during the bending process, and because its position cannot be determined, the finished product produced is unqualified.

Detailed Implementation

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0022] A bending machine for processing tire blowout emergency safety devices, such as Figure 1 and Figure 5As shown, the system includes a worktable 1. A rotating shaft 2 is rotatably mounted on the upper surface of the worktable 1 via a bearing seat 15. A disc 3 is coaxially fixed to the top of the rotating shaft 2. The rotating shaft 2 and the disc 3 can rotate as a whole. A rotating mechanism 9 is connected to the bottom end of the rotating shaft 2 and is installed inside the worktable 1. The rotating mechanism 9 includes a gear 901, which is rotatably mounted inside the worktable 1. The bottom end of the rotating shaft 2 is coaxially fixed to the upper surface of the gear 901. A rack 902 is meshed with the outer wall of the gear 901 and is also slidably mounted on... An electric cylinder 904 is fixed to the right end of the rack 902 within the slide rail 903. When the electric cylinder 904 extends or retracts, it drives the rack 902 to move left or right within the slide rail 903, i.e., the gear 901 rotates clockwise or counterclockwise, causing the rotating shaft 2 and the disc 3 to rotate synchronously. A foot switch 13 is provided on the front surface of the workbench 1, and the foot switch 13 is electrically connected to the electric cylinder 904. The operator controls the electric cylinder 904 by stepping on the foot switch 13, thereby controlling the rotation of the disc 3.

[0023] like Figure 1 and Figure 2 As shown, a curved shaft 5 is coaxially fixed on the upper surface of the disc 3, and a curved seat 4 is also fixed on the upper surface of the disc 3. The curved seat 4 and the curved shaft 5 are arranged correspondingly to each other. A fixed seat 6 is also fixed on the upper surface of the worktable 1. A connecting frame 7 is fixed on the upper surface of the fixed seat 6. A limit seat 10 is connected to the right side of the connecting frame 7. An auxiliary support platform 14 is also fixed on the upper surface of the worktable 1. During the arc calibration process, the worker holds the emergency safety device in hand throughout the process. The worker first limits the emergency safety device through the limit seat 10 and then leans the emergency safety device against the upper end of the auxiliary support platform 14 to improve the stability during the processing and prevent the emergency safety device from shifting position during the processing. After the position is fixed, the worker steps on the foot switch 13 to rotate the rotating shaft 2 and the disc 3. The curved seat 4 rotates accordingly. The curved seat 4 applies a force to the processed end of the emergency safety device. Under the interaction of the curved seat 4, the emergency safety device, and the rotating shaft 2, the emergency safety device bends in arc.

[0024] like Figure 3 and Figure 4 As shown, a limiting pin 11 is provided on the right side of the limiting seat 10. The worker holds the emergency safety device and clamps it onto the outer wall of the limiting pin 11 through the smallest size of the through hole. With the assistance of the limiting pin 11, the position of the emergency safety device is fixed during the bending process.

[0025] In Example 1, during operation, the worker holds the emergency safety device in hand throughout the process. First, the position of the emergency safety device is determined using the limit seat 10 and auxiliary support platform 14 to ensure stability during processing. Then, the worker steps on the foot switch 13, causing the extension end of the electric cylinder 904 to extend outwards. The rack 902 moves to the left, driving the gear 901 to rotate clockwise. This causes the rotating shaft 2 and disc 3 to rotate clockwise, i.e., the curved seat 4 rotates clockwise. Under the mutual compression of the curved seat 4, the emergency safety device, and the rotating shaft 2, the emergency safety device bends in an arc. Then, the extension end of the cylinder 904 retracts, and the gear... When bar 902 moves to the right, it drives gear 901 to rotate counterclockwise, thereby resetting shaft 2, disc 3, and bending seat 4. A first sliding groove 802 is provided on the right side of the limiting seat 10, and a sliding seat 801 is slidably installed in the first sliding groove 802. A limiting pin 11 is fixed on the right side of the limiting seat 10. When the worker bends the emergency safety device, he needs to hold the emergency safety device to determine its position. The setting of the limiting pin 11 can determine the position of the emergency safety device during the bending process, preventing the processed end from extending too far outward, which would lead to the problem of unqualified finished products. Example 2

[0026] Example 2 is based on Example 1, such as... Figure 3 and Figure 4 As shown, the limiting seat 10 is provided with a moving mechanism 8, which includes a slide 801. A first slide groove 802 is provided on the right side of the limiting seat 10, and the slide 801 is slidably installed in the first slide groove 802. A limiting pin 11 is fixed on the right side of the slide 801. The operator can clamp the emergency safety device on the outer wall of the limiting pin 11. A second slide groove 803 is also provided on the upper surface of the limiting seat 10. A bolt 804 is provided in the second slide groove 803. The bottom end of the bolt 804 is fixed to the upper surface of the slide 801, and a wing nut 805 is threaded to the outer wall of the bolt 804. Rotating the wing nut 805 clockwise loosens it so that it can move. The bolt 804 can drive the limiting seat 10 to slide in the first slide groove 802, thus realizing the movement of the limiting pin 11. After the movement is completed, rotating the wing nut 805 counterclockwise tightens it on the upper surface of the limiting seat 10.

[0027] like Figure 3 and Figure 4 As shown, a circular baffle 12 is also fixed to the right end of the limiting pin 11. The diameter of the circular baffle 12 is larger than the diameter of the limiting pin 11, and the diameter of the circular baffle 12 is smaller than the size of the largest through hole on the emergency safety device. The worker holds the emergency safety device and makes the circular baffle 12 pass through the largest size of the through hole on the machined end, and makes the emergency safety device fit over the limiting pin 11. Then, the emergency safety device is moved to lock the through hole onto the outer wall of the limiting pin 11.

[0028] In Example 2, when the wing nut 805 moves forward, the bolt 804 drives the slide block 801 to move forward within the first slide groove 802, i.e., the limit pin 11 moves forward. When the wing nut 805 moves backward, the bolt 804 drives the slide block 801 to move backward within the first slide groove 802, i.e., the limit pin 11 moves backward. This allows the slide block 801 to move forward and backward within the first slide groove 802, flexibly changing the position of the limit pin 11. This is suitable for bending and processing emergency safety devices of different specifications and sizes. The diameter of the circular baffle 12 is set larger than the size of the through hole of the emergency safety device to prevent operator errors from causing the emergency safety device to slip off the limit pin 11, further improving the stability during the processing.
