Description

Technical Field

[0001] This utility model relates to the field of wheel hub spinning technology, and in particular to a split-type spinning roller. Background Technology

[0002] In the aluminum alloy wheel casting and spinning process, the spinning roller of the spinning machine is a key forming component, and its performance and maintenance efficiency directly affect production efficiency. Currently, the integrated spinning rollers commonly used in the industry have many insurmountable technical defects, becoming a significant bottleneck restricting the improvement of production efficiency. First, when facing the processing needs of aluminum alloy wheels of different specifications and models, the integrated spinning roller requires complete replacement, which is not only cumbersome but also greatly extends equipment adjustment time, making it difficult to adapt to the flexible production requirements of modern production lines with multiple varieties and small batches. Second, during operation, the spinning roller is in direct contact with the wheel blank, bearing enormous pressure and friction, making its surface extremely prone to wear. For integrated spinning rollers, once local wear occurs, even if other parts are intact, the entire roller must be replaced, resulting in significant material waste and a substantial increase in production costs. Furthermore, the time-consuming process of replacing the entire spinning roller severely restricts production progress; the replacement process for integrated spinning rollers takes at least 3 hours to complete, reducing equipment utilization and overall production efficiency.

[0003] Therefore, developing a new type of rotary roller structure for practical production is an urgent problem to be solved. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the integrated rotary roller in the existing technology, such as poor flexibility, high maintenance cost, and long replacement time, and to provide a split rotary roller to achieve rapid changeover, reduce maintenance costs, and improve production efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A split-type spinning roller includes a detachably connected carrier core and a spinning ring. The carrier core has mounting holes that match the mounting position of the spinning machine. The carrier core also has multiple evenly distributed bolt holes. The spinning ring has corresponding through holes at the positions of the bolt holes of the carrier core, for connecting and fixing to the carrier core with bolts.

[0006] Preferably, the bearing core has a T-shaped structure, and the spinning ring has a T-shaped hole that mates with the T-shaped shaft hole of the bearing core.

[0007] Preferably, the fitting clearance between the T-hole and the T-structure is 0.02-0.05 mm.

[0008] Preferably, the outer edge of the T-shaped structure of the bearing core is provided with a frustum structure, and the spinning ring is provided with a conical structure at the position corresponding to the frustum structure of the bearing core, the taper of the conical structure being consistent with the taper of the frustum structure.

[0009] Preferably, the taper of the frustum structure is between 1:1 and 1:2.

[0010] Preferably, the bearing core and the spinning ring are provided with a number of circumferentially evenly distributed reamed holes. The beneficial effects of this utility model are as follows: The split-type rotary roller provided by this utility model solves the problem of poor flexibility of traditional integrated rotary rollers by decomposing the integrated structure into a detachable assembly structure of the bearing core and the spinning ring. This allows for faster replacement of the spinning ring only when processing different specifications of wheel hubs, significantly shortening equipment adjustment time and adapting to flexible production needs. At the same time, addressing the pain point of high maintenance costs, only the spinning ring needs to be replaced after wear, and the bearing core can be reused to reduce material waste. It effectively solves the problem of long replacement time, shortening the replacement process from 3 hours to 1.5 hours, ensuring equipment utilization and comprehensively improving production efficiency. In addition, through the T-shaped structure and T-slot fit, the self-aligning of the frustum and conical surface, and the reamed hole bolt connection, the problem of insufficient assembly accuracy that may exist in the split structure is solved, ensuring concentricity and connection stability, and guaranteeing processing quality.

[0016] 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.

[0017] like Figure 1-2As shown, a split-type spinning roller includes a detachably connected support core 10 and a spinning ring 20. The support core 10 mainly serves as a support and transition connection, while the spinning ring 20 directly contacts the aluminum alloy wheel hub blank during spinning operations, undertaking the main forming and rolling work. The support core 10 has mounting holes 11 that match the mounting position of the spinning machine, ensuring that the support core 10 can be securely mounted on the spinning machine. The support core 10 has multiple evenly distributed bolt holes 12, and the spinning ring 20 has corresponding through holes 21 at the positions of the bolt holes 12 of the support core 10, so as to connect to the support core 10 with bolts.

[0018] During assembly, the bearing core 10 is installed on the spinning machine through the mounting holes 11. The spinning ring 20 is aligned with the bearing core 10, ensuring that the through holes 21 on the spinning ring 20 correspond one-to-one with the bolt holes 12 on the bearing core 10. Bolts are then passed through the through holes 21 and bolt holes 12, and the bolts are tightened with a wrench to ensure that the bearing core 10 and the spinning ring 20 are tightly joined to form a complete spinning roller. The assembled spinning roller is then installed on the spinning machine through the mounting holes 11, and the wheel hub spinning operation can then be performed. When the spinning ring 20 of the spinning roller wears and affects the forming quality of the aluminum alloy wheel hub, or when the wheel type needs to be changed, the operator uses a wrench to loosen and remove the bolts connecting the bearing core 10 and the spinning ring 20. The worn spinning ring 20 is then removed, replaced with a new, compatible spinning ring 20, and finally, the new spinning ring 20 is connected and tightened to the bearing core 10 with bolts. The entire replacement process is simple to operate, requiring only the replacement of the spinning ring 20, eliminating the hassle of disassembling the bearing core 10 connected to the spinning machine, and greatly shortening the replacement time.

[0019] In practical use, actual production verification has shown that the split-type spinning roller of this embodiment ensures the operational stability of the spinning machine, and the forming quality of the aluminum alloy wheel hub is comparable to that using an integrated spinning roller, fully meeting production requirements. At the same time, replacement time and costs are significantly reduced, resulting in a substantial improvement in production efficiency.

[0020] The bearing core 10 is made of high-strength alloy steel with good mechanical properties, capable of withstanding the enormous pressure and torque during the spinning process. The spinning ring 20 is made of wear-resistant materials such as high-speed steel or alloy tool steel, capable of withstanding long-term friction and rolling with the aluminum alloy wheel hub blank. The shape of the spinning ring 20 is designed according to the forming requirements of the aluminum alloy wheel hub, and its outer surface curvature, dimensions, and other parameters are matched with the wheel hub design to ensure that the spun wheel hub meets quality standards. In a preferred embodiment, the bearing core 10 is configured with a T-shaped structure, and the spinning ring 20 has a T-shaped hole 22 that mates with the T-shaped shaft hole of the bearing core 10. Preferably, the size of the T-shaped hole 22 and the fitting clearance between the T-shaped structure are controlled within the range of 0.02-0.05 mm. During assembly, the bearing core 10 and the spinning ring 20 are engaged through the T-shaped structure and the shaft hole of the T-shaped hole 22, achieving precise radial positioning between them.

[0021] Preferably, the outer edge of the T-shaped structure of the bearing core 10 is provided with a frustum structure 13, and a conical structure 23 is provided on the spinning ring 20 at the position corresponding to the frustum structure 13 of the bearing core 10. The taper of the conical structure 23 is consistent with the taper of the frustum structure 13, ensuring that self-alignment can be achieved through the mutual contact of the conical surfaces during assembly, effectively improving the concentricity of the two. Preferably, the taper of the frustum structure 13 is between 1:1 and 1:2 to ensure a good fit with the conical structure 23 on the spinning ring 20.

[0022] Preferably, the bearing core 10 and the spinning ring 20 are provided with a plurality of circumferentially evenly distributed reamed holes 30 to ensure a transition fit with the shank of the reamed hole 30 bolt, thereby improving the assembly accuracy of the bearing core 10 and the spinning ring 20. During assembly, the reamed hole 30 bolt passes through the reamed holes 30 on the bearing core 10 and the spinning ring 20 and is screwed into the bottom thread of the reamed hole 30 of the bearing core 10, achieving a high-precision assembly connection. 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.
