Description

Technical Field

[0001] This utility model relates to the field of wheel hub manufacturing technology, and in particular to a wheel hub spinning device. Background Technology

[0002] As a core safety component of a vehicle's driving system, the manufacturing quality of aluminum alloy wheels directly impacts the safety of drivers and passengers. In wheel forming processes, forging and spinning are widely used due to their ability to significantly improve the material properties of the rim. Quality control during the spinning process is crucial in determining the final strength, precision, and reliability of the wheel. However, in traditional spinning production, due to plastic deformation, excess material inevitably overflows from the wheel surface, forming flash. This flash not only affects the product's appearance and dimensional accuracy but also places a significant burden on subsequent processing, increasing the time and cost of deburring. Therefore, effectively controlling and resolving the flash problem during spinning is key to improving the safety, efficiency, and final quality of wheel manufacturing.

[0003] Therefore, developing a new type of wheel hub spinning device for practical production to improve the spinning process and enhance product quality and production efficiency is an urgent problem to be solved. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems by providing a novel wheel hub spinning device. This device includes a semi-circular double-edged cutting tool and a spinning roller, aiming to solve the flash problem, improve the spinning process, and thereby enhance product quality and production efficiency.

[0005] The technical solution adopted in this utility model is as follows: A wheel hub spinning device includes a rolling assembly for spinning wheel hubs. The rolling assembly includes a bearing fixedly connected to the feeding mechanism of the spinning machine. A spinning roller is rotatably connected to the bearing. A cutting tool is also fixedly installed on the bearing corresponding to the wheel hub blank for synchronously cutting and removing flash during the spinning operation.

[0006] Preferably, a fixed shaft is provided on the bearing seat, the spinning roller is rotatably connected to the fixed shaft, and the cutting tool is fixedly connected to the fixed shaft.

[0007] Preferably, the cutting tool has an arc-shaped double-edged structure, with the two cutting edges of the cutting tool respectively located at both ends of the arc-shaped tool along its length.

[0008] Preferably, multiple rolling assemblies are arranged along the circumference of the wheel hub blank to achieve multi-station collaborative operation.

[0009] Preferably, three rolling assemblies are provided along the circumference of the wheel hub blank, and the three rolling assemblies are arranged at 90° intervals along the circumference of the wheel hub blank.

[0010] Preferably, the ratio of the radius of the spinning roller to the height of the cutting edge of the tool is 1:1 to 1.5:1.

[0011] Preferably, the three rolling components are configured in ratios of 1.5:1, 1.2:1 and 1:1 along the rotation direction of the wheel hub blank. The beneficial effects of this utility model are as follows: Functional integration is achieved by integrating the rolling assembly with the cutting tool, enabling simultaneous spinning and flash removal, eliminating the need for a separate flash removal process, shortening the production flow, and improving production efficiency. Simultaneously, it avoids dimensional deviations and surface defects caused by flash accumulation, thus improving product quality. The optimized structural design, with a fixed shaft enhancing the assembly stability of the spinning roller and cutting tool, ensures consistent spinning accuracy and flash removal effect, improving device reliability. The arc-shaped double-edged tool is compatible with both forward and reverse rotation of the hub, eliminating the need for tool adjustment, reducing downtime during reversals, and improving equipment utilization. The three rolling assemblies are evenly distributed at 90° circumferential angles, enabling multi-station collaborative operation, ensuring uniform force on the hub, reducing the risk of deformation caused by single-point stress concentration, offsetting radial unbalanced forces, reducing vibration, improving geometric accuracy, and increasing production capacity.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] like Figure 1-3As shown, a wheel hub spinning device includes a rolling assembly 10 for wheel hub spinning. The rolling assembly 10 includes a bearing 11 fixedly connected to a spinning machine feed mechanism 30, and spinning rollers 12 are rotatably connected to the bearing 11. To solve the problem of flash during the wheel hub spinning process, a cutting tool 13 is fixedly provided on the bearing 11 corresponding to the wheel hub blank for synchronously cutting and removing flash during the spinning operation.

[0019] During the production process, after the wheel hub blank enters the spinning process, it is fixed on the spinning die 20 and begins to rotate. The spinning machine feed mechanism 30 drives the rolling assembly 10 to approach the rotating wheel hub blank, and the spinning roller 12 abuts against the wheel hub blank to perform the spinning operation. As the spinning process proceeds, flash gradually forms on the surface of the workpiece, spreading circumferentially along the die. At this time, the cutting tool 13 feeds at the circumferential diffusion radius of the flash to remove the flash, and finally the spinning and flash removal are completed simultaneously. This embodiment integrates the cutting tool 13 on the rolling assembly 10, realizing the simultaneous spinning and flash removal, eliminating the separate flash removal process in the traditional process, shortening the production process, and improving production efficiency; at the same time, it avoids dimensional deviations and surface defects caused by flash accumulation, thus improving product quality.

[0020] Preferably, a fixed shaft 14 is provided on the bearing seat 11, the spinning roller 12 is rotatably connected to the fixed shaft 14, and the cutting tool 13 is fixedly connected to the fixed shaft 14. During operation, the spinning roller 12 abuts against the hub blank and rotates synchronously to roll the hub blank, while the cutting tool 13 is fixedly set to remove the flash from the hub blank. The rotational movement of the spinning roller 12 and the fixed cutting of the cutting tool 13 form a precise match, ensuring the consistency of spinning forming accuracy and flash removal effect, and improving the reliability of the device operation.

[0021] Preferably, the cutting tool 13 has an arc-shaped double-edged structure, with two cutting edges 131 respectively positioned at both ends of the arc-shaped tool's length, allowing the cutting tool 13 to meet the processing requirements of different rotation directions of the wheel hub blank. Regardless of whether the spinning die 20 drives the wheel hub to rotate clockwise or counterclockwise, one of the cutting edges 131 remains in an effective cutting position with the wheel hub flash, and the cutting direction matches the flash diffusion direction, eliminating the hassle of adjusting the tool due to changes in rotation direction and ensuring operational efficiency. The arc-shaped double-edged structure overcomes the limitations of traditional single-edged tools. Through the design of the bidirectional cutting edges 131, seamless adaptation during rotation direction switching is achieved, eliminating the time cost of stopping to adjust the tool during direction changes, while ensuring the continuity and stability of flash removal during processing in different rotation directions.

[0022] Preferably, multiple rolling assemblies 10 are arranged along the circumference of the wheel hub blank to achieve multi-station collaborative operation. Preferably, three rolling assemblies 10 are provided, and the three rolling assemblies 10 are arranged at 90° intervals along the circumference of the wheel hub blank, making the force distribution on the wheel hub blank more uniform. The multi-station layout of the three rolling assemblies 10 evenly distributed at 90° intervals in the circumferential direction makes the force on the wheel hub blank more balanced during the spinning process, significantly reducing the risk of blank deformation caused by single-point stress concentration in traditional single-roller operation; at the same time, the collaboration of multiple components can offset radial unbalanced forces, reduce workpiece vibration, and improve the geometric accuracy of the wheel hub; in addition, the parallel operation of the three stations significantly shortens the processing time and increases production capacity.

[0023] Preferably, the ratio of the radius of the spinning roller 12 to the height of the cutting edge 131 (i.e., the distance between the cutting edge 131 and the axis of the fixed shaft 14) is 1:1 to 1.5:1 to ensure the flash removal effect. Preferably, when the flash height is 20-25mm, the ratio of the radius of the spinning roller 12 to the height of the cutting edge 131 is 1.5:1; when the flash height is 15-20mm, the ratio is 1.2:1; and when the flash height is 10-15mm, the ratio is 1:1. This embodiment sets an appropriate ratio of the radius of the spinning roller 12 to the height of the cutting edge 131 for different flash heights, enabling the cutting tool 13 to accurately match the flash diffusion range, ensuring the flash removal effect and improving the flatness of the hub; at the same time, it avoids the problems of over-cutting or under-cutting, reducing material waste and the need for secondary processing.

[0024] Preferably, the three rolling components 10 are configured in ratios of 1.5:1, 1.2:1, and 1:1 along the rotation direction of the wheel hub blank. This gradient ratio configuration along the rotation direction allows the wheel hub blank to undergo progressive processing from coarse to fine during the rolling process. The preceding components focus on efficiently removing large-sized flash, while the subsequent components focus on fine finishing, further improving the processing accuracy of the rim edge. At the same time, the gradient matching reduces the workload of individual components, extends the service life of the tools and rollers, and reduces equipment maintenance costs. The above-disclosed embodiments are merely specific examples of this utility model, but this utility model is not limited thereto. For those skilled in the art, any modifications made without departing from the principle of this utility model should be considered as protected by this utility model.
