Description

Technical Field

[0001] This utility model relates to the field of wheel rim production technology, and in particular to a wheel rim rolling machine. Background Technology

[0002] A wheel rim, also called a wheel ring, steel rim, wheel, or tire rim, is a cylindrical metal component that supports the tire and is centrally mounted on the axle. Wheel rims come in many varieties depending on their diameter, width, forming method, and material. In the past, passenger car wheel rim bearings were mostly paired single-row tapered roller or ball bearings. With technological advancements, passenger cars now widely use passenger car wheel rim units. The application range and usage of wheel rim bearing units have been increasing, evolving to the third generation: The first generation consisted of double-row angular contact bearings; the second generation had a flange on the outer raceway for fixing the bearing, allowing for easy mounting of the bearing onto the axle and securing it with a nut, making car maintenance easier; the third generation wheel rim bearing units combine the bearing unit with an anti-lock braking system. The wheel rim unit is designed with an inner flange and an outer flange. The inner flange is bolted to the drive shaft, and the outer flange mounts the entire bearing together.

[0003] In the wheel rim manufacturing process, rolling is a key step in shaping the rim's ring-shaped base. The raw materials for wheel rim production are typically metal sheets of specific dimensions. After pre-processing such as cutting and stamping, these sheets are precisely fed into a rolling machine. The rolling machine uses the squeezing and rotating action of rolling rollers to gradually bend the flat metal sheets, ultimately forming a ring-shaped semi-finished product that meets the rim's dimensional requirements.

[0004] However, under the current wheel rim production technology system, after the rolling machine completes the rolling of the metal sheet, the process of removing the rolled wheel rim semi-finished product from the rolling machine still mostly relies on manual operation. Operators often need to put their hands or even their entire arms into the rolling machine and use the strength of their hands to peel and remove the wheel rim semi-finished product from the fixed structure of the equipment. If the operator makes a mistake, it can easily lead to a safety accident. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rolling machine for rim production, which solves the aforementioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A rim rolling machine includes a base, a support plate fixedly mounted on the top of the base, a rotating assembly arranged on the opposing surface of the support plate, a rolling roller arranged inside the support plate through the rotating assembly, the rolling roller being rotatably connected to the support plate, a support assembly and a lifting assembly arranged on the top of the base, a limit roller arranged on the top of the base through the lifting assembly, a moving assembly arranged on the rear side of the base, and a pusher arranged on the top of the base through the moving assembly.

[0007] Preferably, the rotating assembly includes a rotary motor disposed on the opposing surface of the support plate, a first gear is fixedly mounted on the output end of the rotary motor, a second gear is meshed on the surface of the first gear, and the second gear is fixedly connected to the rolling roller.

[0009] Preferably, the lifting assembly includes a second hydraulic push rod disposed on the top of the base, a lifting frame fixedly installed at the output end of the second hydraulic push rod, a limiting roller rotatably connected to the lifting frame, a second guide column fixedly installed at the bottom of the lifting frame, a second guide sleeve slidably connected to the surface of the second guide column, and the second guide sleeve fixedly connected to the base.

[0010] Preferably, the moving component includes a drive motor disposed on the rear side of the base, a screw fixedly mounted on the output end of the drive motor, a moving frame threadedly connected to the surface of the screw, the moving frame being fixedly connected to the push frame, a slide rod slidably connected inside the moving frame, and the slide rod being fixedly connected to the base.

[0011] Preferably, there are multiple sliding rods, and the multiple sliding rods are symmetrically distributed.

[0012] Preferably, the first guide post has a rectangular rod-shaped structure, and the first guide sleeve is adapted to the first guide post.

[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. 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.

[0017] Example: Refer to Figure 1-5A rim rolling machine includes a base 1, a support plate 2 fixedly mounted on the top of the base 1, a rotating assembly on the opposing surfaces of the support plate 2, and a rolling roller 6 mounted inside the support plate 2 via the rotating assembly. The rolling roller 6 is rotatably connected to the support plate 2. A support assembly is also provided on the top of the base 1, including a first hydraulic push rod 7 mounted on the top of the base 1. A support seat 8 is fixedly mounted on the output end of the first hydraulic push rod 7, and a first guide post 10 is fixedly mounted on the bottom of the support seat 8. A first guide sleeve 9 is slidably connected to the surface of the first guide post 10. The first guide post 10 has a rectangular rod-like structure, and the first guide sleeve 9 is adapted to the first guide post 10 and fixedly connected to the base 1. When the support seat 8 moves upward and contacts the rolling roller 6 via the first hydraulic push rod 7, it can support the front side of the rolling roller 6, facilitating more stable rotation of the rolling roller 6. When the support seat 8 separates from the rolling roller 6, the rim can be unloaded. A lifting assembly is provided on the top of the base 1, and a limiting mechanism is provided on the top of the base 1 via the lifting assembly. A positioning roller 15 is mounted on the rear side of the base 1, and a moving assembly is provided on the top of the base 1 via the moving assembly. The moving assembly includes a drive motor 16 located on the rear side of the base 1. A screw 17 is fixedly mounted on the output end of the drive motor 16, and a moving frame 18 is threaded onto the surface of the screw 17. The moving frame 18 is fixedly connected to the push frame 20, and multiple slide rods 19 are slidably connected inside the moving frame 18. The slide rods 19 are symmetrically distributed and fixedly connected to the base 1 via the moving assembly. The design facilitates the forward and backward movement of the pusher 20, enabling automatic unloading of the rim. After the rim is rolled, the support for the rolling roller 6 is removed by the support component. At the same time, the pusher 20 is moved forward by the moving component, which automatically pushes the rolled rim away from the rolling roller 6, facilitating automatic unloading of the rim without the need for manual unloading. This eliminates the need to put an arm inside the rolling machine, making rim production safer.

[0018] Specifically, the rotating assembly includes a rotating motor 3 disposed on the opposing surface of the support plate 2. A first gear 4 is fixedly installed at the output end of the rotating motor 3. A second gear 5 is meshed on the surface of the first gear 4. The second gear 5 is fixedly connected to the rolling roller 6. The rotating assembly facilitates the provision of driving force for the rotation of the rolling roller 6, thereby facilitating the subsequent rolling roller 6 to roll the rim.

[0019] Specifically, the lifting assembly includes a second hydraulic push rod 11 disposed on the top of the base 1, a lifting frame 12 fixedly installed at the output end of the second hydraulic push rod 11, a limiting roller 15 rotatably connected to the lifting frame 12, a second guide column 13 fixedly installed at the bottom of the lifting frame 12, a second guide sleeve 14 slidably connected to the surface of the second guide column 13, and the second guide sleeve 14 fixedly connected to the base 1. The lifting assembly facilitates the provision of driving force for the upper and lower movement of the limiting roller 15, thereby facilitating the extrusion of the rim material by the limiting roller 15, and thus facilitating the rolling of the rim material.

[0020] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0021] In operation: The rim material enters the rolling machine from the right side. The second hydraulic push rod 11 on the right moves the lifting frame 12 and the second guide column 13 upwards along the second guide sleeve 14, causing the limiting roller 15 to move upwards and compress the rim material, resulting in localized bending. Then, the second hydraulic push rod 11 on the right moves the lifting frame 12, the limiting roller 15, and the second guide column 13 downwards along the second guide sleeve 14 back to their original positions. Next, the second hydraulic push rod 11 on the left moves the lifting frame 12 and the second guide column 13 upwards along the second guide sleeve 14, causing the limiting roller 15 to move upwards and compress the rim material again. Finally, the rotating motor... 3 causes the first gear 4 to rotate, the second gear 5 to rotate, and the rolling roller 6 to rotate, thus rolling the rim material. After the rolling process is completed, the second hydraulic push rod 11 on the left causes the lifting frame 12, the limiting roller 15, and the second guide column 13 to move downward along the second guide sleeve 14 back to their original positions. At the same time, the first hydraulic push rod 7 causes the support seat 8 and the first guide column 10 to move downward along the first guide sleeve 9, so that the support seat 8 is separated from the rolling roller 6 by a certain distance. Meanwhile, the drive motor 16 causes the screw 17 to rotate, causing the moving frame 18 to move forward along the slide rod 19, and the push frame 20 to move forward, which can automatically push the rolled rim away from the rolling roller 6.
