The wheel rim expansion and forming mold of this invention is easy to install and disassemble, and replacing the rolling wheel and mandrel can save a significant amount of time.

[0004] However, it still has the following drawbacks in practical use:

[0005] In existing ring forgings, the metal ring will wobble during the continuous rolling process, lacking a limit on the rolling process. At the same time, when rolling the front and rear surfaces of the metal ring, it is necessary to change the surface, which is time-consuming and labor-intensive, reducing the efficiency of ring rolling. Utility Model Content

[0006] The purpose of this utility model is to provide a large-size ring forging rolling die to solve the problems mentioned in the background art, such as the metal ring shaking during the continuous rolling process, the lack of limiting the movement of the metal ring during the rolling process, and the need to change the surface when rolling the front and rear surfaces of the metal ring, which is time-consuming, labor-intensive, and reduces the efficiency of rolling.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a rolling die for large-size ring forgings, including a processing table: a support base is fixedly installed on the top of the processing table, and a limiting rolling component is provided on the front side of the support base;

[0009] The limiting and compacting assembly includes a first support frame, a first cylinder, a limiting frame, a first slide rod, a slider, and a first compacting roller.

The limiting frame is fixedly installed on the top of the first support frame. A first slide rod is fixedly installed inside the limiting frame. Sliders are symmetrically slidably arranged on the first slide rod. A connecting rod is movably hinged between each of the two sliders and the moving block. A first compacting roller is fixedly installed on the right side of each of the two sliders.

[0010] Furthermore, a second support frame is fixedly installed on the front side of the processing table, and a second slide rod is fixedly installed between the inner walls of the left and right sides of the inner cavity of the second support frame. A slide block is fixedly installed at the bottom of the first support frame, and the slide block is slidably disposed outside the second slide rod.

[0011] Furthermore, a second cylinder is fixedly installed on the top of the second support frame, and a second drive rod is fixedly connected to the output end of the second cylinder. The right end of the second drive rod is fixedly installed on the left side of the first support frame.

[0012] Furthermore, two third slide rods are fixedly installed between the upper and lower inner walls of the inner cavity of the processing table, a third cylinder is fixedly installed on the top of the processing table, and a lifting seat is fixedly connected to the bottom output end of the third cylinder. The lifting seat is slidably arranged outside the two third slide rods.

[0013] Furthermore, a rolling wheel is rotatably connected to the front side of the lifting seat, a water spray pipe is fixedly installed on the front side of the support seat, and a support roller is rotatably connected to the front side of the support seat.

[0016] This utility model has the following beneficial effects:

[0017] I. This utility model, by setting a limiting rolling assembly, allows the operator to activate the first cylinder before the ring forging is rolled on the support rollers. This, along with the first drive rod, connecting rod, and slider, drives two first rolling rollers to move closer together, thereby clamping and limiting the front and rear sides of the ring forging. When the ring forging rotates, the two first rolling rollers can roll and shape the front and rear sides of the ring forging, achieving the function of limiting and rolling the ring forging, improving the processing efficiency and quality of the ring forging, and demonstrating strong practicality.

[0018] II. Based on the above-mentioned beneficial effects, by setting up water spray pipes, the high-pressure water flow impacts the metal surface during the rolling of the ring forging, and combined with chemical reaction, effectively removes oxide scale and improves forging efficiency. By setting up a waste collection tank, the waste generated during rolling can be collected uniformly, and the water flow can be used to clean the inside of the waste collection tank to achieve a cleaning effect.

[0028] Please see Figure 1-4 As shown, this utility model is a large-size ring forging rolling die, including a processing table 1: a support base 2 is fixedly installed on the top of the processing table 1, and a limiting rolling component is provided on the front side of the support base 2;

[0029] The limiting and compacting assembly includes a first support frame 3, a first cylinder 4, a limiting frame 5, a first slide rod 6, a slider 7, and a first compacting roller 8. The first support frame 3 is located in front of the support base 2. The first cylinder 4 is fixedly installed on the top of the first support frame 3. The output end of the first cylinder 4 is fixedly connected to a first drive rod 9. A moving block 10 is fixedly installed on the end of the first drive rod 9 away from the first cylinder 4. The limiting frame 5 is fixedly installed on the top of the first support frame 3. The first slide rod 6 is fixedly installed inside the limiting frame 5.

A second slide rod 13 is fixedly installed between the inner walls of the left and right sides of the inner cavity of the second support frame 12. A slide seat 14 is fixedly installed at the bottom of the first support frame 3. The slide seat 14 is slidably disposed outside the second slide rod 13.

[0032] The second slide bar 13 is used to support and guide the movement of the slide block 14, and the second support frame 12 is used to support the second cylinder 15.

[0033] A second cylinder 15 is fixedly installed on the top of the second support frame 12. A second drive rod 16 is fixedly connected to the output end of the second cylinder 15. The right end of the second drive rod 16 is fixedly installed on the left side of the first support frame 3.

[0034] The second cylinder 15 serves as the driving source for the second drive rod 16;

[0035] Working principle: First, by setting up a limiting rolling assembly, before the ring forging is rolled on the support roller 22, the operator starts the first cylinder 4, which uses the first drive rod 9, connecting rod 11 and slider 7 to drive the two first rolling rollers 8 to move closer together, thereby clamping and limiting the front and rear sides of the ring forging. When the ring forging rotates, the two first rolling rollers 8 can roll and shape the front and rear sides of the ring forging. By starting the second cylinder 15, the second cylinder 15 drives the first support frame 3 to move laterally through the second drive rod 16, thereby causing the two first rolling rollers 8 to move closer to the surface of the forging, which is used to adjust the distance between the first rolling rollers 8 and the forging.

[0036] Please see Figure 1-4 As shown, in this embodiment, based on the above embodiment 1, two third slide rods 17 are fixedly installed between the upper and lower inner walls of the inner cavity of the processing table 1, a third cylinder 18 is fixedly installed on the top of the processing table 1, and a lifting seat 19 is fixedly connected to the bottom output end of the third cylinder 18. The lifting seat 19 is slidably arranged outside the two third slide rods 17.

[0037] The third cylinder 18 is activated to drive the lifting seat 19 to move up and down, and the third slide rod 17 is used to limit the lifting seat 19.

[0038] A rolling roller 20 is rotatably connected to the front side of the lifting seat 19, a water spray pipe 21 is fixedly installed on the front side of the support seat 2, and a support roller 22 is rotatably connected to the front side of the support seat 2.

[0039] The rolling roller 20 serves as the main roller to roll and shape the surface of the forging, and the water spray pipe 21 is used to spray water to remove oxide scale from the surface of the forging.

[0040] A fourth cylinder 23 is fixedly installed on the front side of the support base 2. A third drive rod 24 is fixedly connected to the output end of the fourth cylinder 23. A second crushing roller 25 is fixedly installed on the end of the third drive rod 24 away from the fourth cylinder 23.

[0041] The fourth cylinder 23 serves as the driving source for the third drive rod 24, and the second rolling roller 25 is used to roll and shape the outer side of the forging.

[0042] The processing table 1 has a waste collection trough 26 inside, which is located directly below the support roller 22;

[0043] Waste collection trough 26 is used to collect waste generated during rolling.

[0044] Working principle: The operator places the ring forging on the surface of the support roller 22. By activating the third cylinder 18, the lifting seat 19 moves up and down. The movement of the lifting seat 19 causes the front rolling roller 20 to fit against the surface of the ring forging. The support roller 22 rotates, thus cooperating with the rolling roller 20 to roll and form the ring. By activating the fourth cylinder 23, the third drive rod 24 drives the second rolling roller 25 to roll and form the outer side of the forging. During the forging process, a water spray pipe 21 is set up so that when the ring forging is rolled, the high-pressure water jet impacts the metal surface, combined with a chemical reaction, effectively removing oxide scale and improving forging efficiency. A waste collection tank 26 is set up to facilitate the unified collection of waste generated during rolling, and the water jet also cleans the inside of the waste collection tank 26.
