Description

Technical Field

[0001] This utility model relates to the field of machining, specifically a ring rolling machine, and more specifically a rolling roller structure. Background Technology

[0002] After a period of use, the inner roller of a ring rolling machine will experience wear on its working section. Severe wear will create a large gap between the inner roller and the outer adjusting ring, causing material to penetrate the outer radial gap of the ring during rolling and rendering it unusable. Replacing the roller requires disassembling the entire outer adjusting ring to replace the inner roller. Since the inner roller is a single piece, severe wear renders it unusable and necessitates its complete scrapping. This increases the manufacturing cost of the rolling tool, increases the labor intensity for workers replacing the tool, and reduces production efficiency. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses a rolling wheel structure for a rolling mill with a ring, comprising a wheel seat, an expansion ring on the outer diameter of the wheel seat that fits into a wheel frame, and a pressure cap connected to the end of the wheel seat by bolts; the wheel frame is fitted radially outside the wheel seat and the expansion ring, and the ring is fitted on the left end of the radially outer side of the wheel frame, with a flat key between the ring and the wheel frame; the wheel frame and the ring are axially connected by screws; the right end of the radially outer side of the wheel frame has the same outer diameter as the ring; an outer adjusting ring is fitted radially outside the wheel frame and the ring, and the outer adjusting ring is axially fixed to the wheel frame by positioning bolts, with positioning bolts spaced at equal angles along the circumference.

[0004] For ease of disassembly, a radial clearance is provided between the wheel rim and the wheel frame.

[0005] A radial clearance is provided between the outer adjustment ring and the wheel frame and wheel ring.

[0006] The wheel ring mounting hole has countersunk holes at both ends, and the wheel ring and wheel frame are connected by countersunk cylindrical head screws.

[0007] The wheel frame keyway is equipped with a horizontal keyway to secure the flat key, while the wheel ring is equipped with a through keyway to enable quick replacement.

[0008] The advantages of this invention are: the keyway on the wheel ring facilitates processing and assembly; the wheel ring can be disassembled, reversed, and reassembled after wear and can still be used; the rolling wheel ring is made of mold steel, and the wheel frame is made of medium carbon steel, allowing for long-term cyclic use without replacement; replacing the wheel ring reduces the manufacturing cost of the rolling wheel compared to replacing the entire inner wheel. The wheel ring and wheel frame are connected by a double-fastening anti-rotation connection using countersunk head screws and a flat key, preventing the wheel ring from rotating and shearing the countersunk head screws during rolling, thus avoiding disruption to normal rolling operations. When changing products, only the wheel ring needs to be replaced, improving production efficiency and reducing the labor intensity of workers. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] As shown in the figure, this utility model includes a wheel seat 1, with an expansion ring 2 fitted around the outer diameter of the wheel seat 1. A pressure cap 3 is bolted to the end of the wheel seat 1. A wheel frame 4 is fitted on the radially outer side of the wheel seat 1 and the expansion ring 2. A wheel ring 5 is fitted on the radially outer side of the wheel frame 4, and a flat key 6 is provided between the wheel ring 5 and the wheel frame 4. The outer diameters of the wheel frame 4 and the wheel ring 5 are the same. An outer adjusting ring 7 is fitted on the radially outer side of the wheel frame 4 and the wheel ring 5. The outer adjusting ring 7 is axially fixed to the wheel frame 4 by positioning bolts 11, and positioning bolts 11 are provided at equal angular intervals along the circumference. For easy disassembly, a radial gap is provided between the wheel ring 5 and the wheel frame 4, and a radial gap is provided between the outer adjusting ring 7 and the wheel frame 4 and the wheel ring 5.

[0014] The wheel ring 5 has countersunk holes 51 at both ends of the mounting hole, and the wheel ring 5 is connected to the wheel frame 4 by countersunk cylindrical head screws 12.

[0015] If the wheel rim is worn and unusable, it can be disassembled, turned around, and reinstalled for reuse.

[0016] The wheel frame 4 does not come into contact with the ring 8 during the rolling process and is therefore undamaged, allowing for repeated use. The mandrel 9 and the outer end face of the outer adjusting ring 7 have a gap, allowing them to move relative to each other as the wall thickness of the ring 8 decreases and its outer diameter increases during the rolling process.

[0017] The beneficial effects of this utility model are as follows: The original integral inner wheel is designed as a modular unit. When the wheel ring is worn and needs replacement, it is not necessary to completely disassemble the inner wheel and outer adjusting ring; only the wheel ring 5 needs to be removed to complete the rolling wheel assembly. Simultaneously, a flat key 6 is provided between the wheel ring 5 and the wheel frame 4, the wheel frame 4 has a fixed horizontal keyway A, and the wheel ring has a through keyway B for easy assembly. This is to prevent sudden torque increases in the countersunk head screw 12 during the ring rolling machine's operation, which could cause shear deformation or breakage and affect normal production. When the wheel ring 5 and wheel frame 4 become stuck due to rolling or grinding and cannot be disassembled, the rolling wheel is first removed, the outer adjusting ring 7 is removed, and the wheel ring 5 is pushed out using a fully threaded bolt with the threaded hole C of the wheel frame positioning bolt 11. The countersunk head screw 12 mounting holes have countersunk holes 51 on both sides, improving wheel ring utilization and reducing manufacturing costs. This utility model's structure allows for quick assembly and disassembly, improving production efficiency while reducing the workload of the ring rolling operator and the manufacturing cost of the rolling wheel.
