Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to an anti-wrinkle support device for motorcycle pipe bending. Background Technology

[0002] In motorcycle manufacturing, the tube is a core load-bearing and connecting component. Its structural strength and appearance precision directly determine the motorcycle's driving safety, handling stability, and service life. Tubes often need to be bent to form a specific curvature to fit the motorcycle's compact spatial layout and streamlined appearance design. When the tube is bent, the inner tube wall is prone to wrinkles and dents due to compression, while the outer tube wall is prone to cracking due to tension. In particular, inner wrinkles not only damage the appearance of the tube but also cause local stress concentration, significantly reducing the tube's load-bearing capacity. Therefore, a special support device must be used in the tube bending process to ensure the quality of the bending.

[0003] Currently, many existing support devices require the mandrel size to be strictly matched with the inner diameter of the vehicle tube during use. When changing to a vehicle tube of a different diameter, a new mandrel needs to be customized, which takes a long time and results in high equipment costs, easily affecting the processing efficiency of the vehicle tube. To address these issues, we propose an anti-wrinkle support device for bending motorcycle vehicle tubes. Utility Model Content

Each of the guide blocks has a certain curvature on the side near the tapered adjusting rod, and the side of each guide block near the tapered adjusting rod is adapted to the outer surface of the tapered adjusting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device, through the cooperation of a tapered adjusting rod and a support block, can flexibly adjust the expansion range of the arc plate to adapt to the processing needs of different pipe diameters. It eliminates the need for custom-made mandrels for different pipe diameters, significantly reducing equipment costs and changeover time, and improving processing efficiency.

A nut seat 201 is fixedly connected to the end of the support spindle body 2 away from the positioning seat 1. The internal thread of the nut seat 201 is compatible with the adjusting thread 601. The outer surface of the adjusting knob 602 has anti-slip texture. The through hole 9 is located at the center of the support spindle body 2 and penetrates the support spindle body 2. The internal space is used to accommodate the tapered adjusting rod 6, providing a channel for the movement of the tapered adjusting rod 6 and ensuring that the tapered adjusting rod 6 can move stably along the axis of the support spindle body 2. The tapered adjusting rod 6 is located inside the through hole 9 and has an overall tapered structure. The small end has an adjusting thread 601 and is fixedly connected to the adjusting knob 602. The adjusting knob 602 can be rotated to adjust the rod. 02 Axial movement is achieved, thereby generating radial compression force on the guide block 301. The adjusting thread 601 is formed on the outer surface of the small end of the tapered adjusting rod 6 and is adapted to the internal thread of the nut seat 201. Through thread meshing transmission, the rotational motion of the adjusting knob 602 is converted into the axial linear motion of the tapered adjusting rod 6, achieving precise displacement control. The adjusting knob 602 is fixedly connected to the small end of the tapered adjusting rod 6, and the outer surface is provided with anti-slip texture, which makes it easy for the operator to hold and rotate it by hand or tool. The anti-slip texture can increase the friction between the hand and the knob, avoid slippage during rotation, and improve the convenience of operation and adjustment efficiency. The nut seat 201 is fixedly connected to the end of the support spindle body 2 away from the positioning seat 1. The nut seat 201 is provided with an internal thread adapted to the adjusting thread 601, which cooperates with the adjusting thread 601 of the tapered adjusting rod 6 to form a threaded pair, providing support and guidance for the movement of the tapered adjusting rod 6 and ensuring the stability of the adjustment process.

[0024] A set of mounting grooves 5 are formed on the outer surface of the support mandrel body 2. Each mounting groove 5 has a support block 3 inside. An arc plate 4 is fixedly connected to the end of each support block 3 away from the mounting groove 5. A guide block 301 is fixedly connected to the end of each support block 3 away from the arc plate 4. A guide hole 7 is formed on the inner bottom wall of each mounting groove 5. A spring connecting groove 501 is formed on the inner bottom wall of each mounting groove 5. A telescopic spring 8 is formed inside each spring connecting groove 501. An auxiliary groove 302 is formed on the side of each support block 3 away from the arc plate 4. The size of each auxiliary groove 302 is adapted to the telescopic spring 8. The side of each guide block 301 near the tapered adjusting rod 6 has a certain curvature. One side of each support block 3 is adapted to the outer surface of the tapered adjusting rod 6. The mounting groove 5 is a groove opened on the outer surface of the support spindle body 2, which is used to accommodate the support block 3. At the same time, the bottom wall of the groove is provided with a guide hole 7 and a spring connecting groove 501 to provide space and positioning for the installation of the support block 3 and the telescopic spring 8. The support block 3 is set inside each mounting groove 5, with one end fixedly connected to the arc plate 4 and the other end fixedly connected to the guide block 301. An auxiliary groove 302 is opened on the side away from the arc plate 4, which can move radially along the guide hole 7 when the guide block 301 is under force, thereby driving the arc plate 4 to move closer to or away from the inner wall of the vehicle tube. The arc plate 4 is fixedly connected to the end of the support block 3 away from the mounting groove 5. The plate surface is arc-shaped and adapted to the curvature of the inner wall of the vehicle tube, so that it can fit the vehicle tube under the action of the support block 3. The inner wall of the pipe provides internal support during pipe bending, preventing wrinkles from forming on the pipe wall. A guide block 301 is fixedly connected to the end of the support block 3 away from the arc plate 4. The side closest to the tapered adjusting rod 6 has an arc that matches the outer surface of the tapered adjusting rod 6, allowing it to contact the outer surface of the tapered adjusting rod 6 tightly and convert the axial force of the tapered adjusting rod 6 into its own radial force, driving the support block 3 to move. A guide hole 7 is opened in the inner bottom wall of each mounting groove 5, cooperating with the corresponding structure of the support block 3 to guide the movement direction of the support block 3, ensuring that the support block 3 can only move linearly in the radial direction, avoiding deviation during movement that could affect the support effect of the arc plate 4. A spring connecting groove 501 is opened in the inner bottom wall of each mounting groove 5, with internal space for placing a telescopic spring 8. The telescopic spring 8 serves a positioning function, preventing it from shifting during compression or extension and ensuring that the spring force acts stably on the support block 3. The telescopic spring 8 is located inside each spring connecting groove 501, with one end contacting the bottom wall of the spring connecting groove 501 and the other end embedded in the auxiliary groove 302 of the support block 3. In its natural state, it generates an outward elastic force on the support block 3. When the tapered adjusting rod 6 retracts, it can drive the support block 3 and the arc plate 4 to reset through the elastic force, making it easier to remove the vehicle tube. The auxiliary groove 302 is opened on the side of the support block 3 away from the arc plate 4, and its size is adapted to the telescopic spring 8. It is used to accommodate the end of the telescopic spring 8, making the connection between the telescopic spring 8 and the support block 3 more stable, ensuring that the spring force can be effectively transmitted to the support block 3, and realizing the stable reset of the support block 3.

[0025] The working principle of this utility model is as follows:

[0026] When using this equipment, it is first fixed to the pipe bending machine by the positioning seat 1. The operator places the pipe to be bent on the outside of the support mandrel body 2, which is composed of multiple arc plates 4. Then, the operator rotates the adjustment knob 602 clockwise, which moves the conical adjustment rod 6 into the support mandrel body 2. The large-diameter end of the conical adjustment rod 6 radially presses multiple guide blocks 301 with arc surfaces, forcing the support block 3 to overcome the elastic force of the telescopic spring 8 and expand evenly outward along the guide hole 7. This makes the arc plate 4 fit tightly against the inner wall of the pipe, providing comprehensive support. During the pipe bending process, this support can effectively resist the compressive force on the inside of the pipe and prevent wrinkles from forming. Finally, after the pipe bending is completed, the operator rotates the adjustment knob 602 counterclockwise, and the conical adjustment rod 6 retracts. Under the action of the elastic force of the telescopic spring 8, the support block 3 and the arc plate 4 retract, and the formed pipe can be easily removed, realizing quick changeover.
