Description

Technical Field

[0001] This utility model relates to a steel wheel rim straightening and press-fitting device, belonging to the field of wheel rims. Background Technology

[0002] Light truck steel wheels are currently manufactured by rolling the rims using a roll forming machine and spinning the spokes. The rims and spokes are pressed together using a pressing mold and equipment. However, the spinning, punching, and deburring processes on the spokes significantly affect the flatness of the spoke mounting surface, resulting in unevenness and inconsistency. To ensure product testing performance and mounting surface accuracy, an additional pressing and straightening process is required for the spoke mounting surface.

[0003] The existing equipment cannot perform other operations during the pressure holding process. During the entire pressure holding process, the rim and spokes are first placed on the mold and aligned before the press fitting is performed. After the press fitting is completed, the workpiece is removed and a new workpiece is placed. This results in a lot of wasted working time during material handling and unloading, leading to low efficiency in steel rim alignment and press fitting. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steel rim straightening and press-fitting device.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A steel wheel rim straightening and pressing device includes a worktable and two wheel rim positioning rings. Two lower mold support plates are fixedly mounted on the top of the worktable. A lower mold base is fixedly mounted on the top surface of the lower mold support plates. The wheel rim positioning rings pass through the lower mold core of the lower mold base and are set on the upper outer surface of the lower mold base. A movable frame is provided on the lower mold base. A lifting plate is provided on the movable frame. A lifting component connected to the lifting plate is provided on the movable frame. An upper mold base corresponding to the lower mold base is fixedly mounted at the bottom end of the lifting plate. A through-hole for a lifting rod to pass through is opened on the wheel rim positioning rings. Two lifting components are provided below the bottom end of the worktable, and the lifting components are connected to the lifting rod.

[0007] Furthermore, the lifting component is a hydraulic cylinder, the hydraulic output rod of the hydraulic cylinder is connected to the lifting plate, and vertical grooves are opened on the inner sides of the four support columns of the moving frame.

[0008] Furthermore, each of the four corners of the lifting plate is fixed with a slider extending into the vertical groove. Each end face of the slider facing the vertical groove is provided with a ball bearing, and three-quarters of the volume of the ball bearing is movably embedded in the slider.

[0009] Furthermore, transverse sliding grooves are provided on both sides of the outer wall of the workbench, and auxiliary sliders located inside the transverse sliding grooves are fixed on the four support columns of the movable frame.

[0010] Furthermore, each end face of the secondary slider facing the transverse slide groove is provided with a secondary ball bearing, three-quarters of the volume of which is movably embedded in the secondary slider. Hydraulic cylinders are provided on both sides of the outer wall of the worktable, and the hydraulic output rods of the hydraulic cylinders are connected to the moving frame.

[0011] Furthermore, the lifting component includes a lifting ring located at the top of the lower mold plate. Multiple lifting columns are fixedly provided at the top of the lifting ring. Each lifting column has an aligning plate fixedly provided at its top, facing the rim positioning ring. Each aligning plate has a lifting rod fixedly provided at its top.

[0012] Furthermore, a U-shaped frame is located at the bottom of the workbench, on which a hydraulic cylinder three is fixedly mounted. A connecting plate is fixedly mounted at the top of the hydraulic output rod of the hydraulic cylinder three, and two connecting rods penetrating the workbench are fixedly mounted at the top of the connecting plate. The top of the connecting rods is connected to the bottom of the lifting ring.

[0013] The beneficial effects of this utility model are:

[0014] Two wheel rims are placed inside the wheel rim positioning rings, and two wheel spokes are placed on the lower mold core of the lower mold base. Then, the lifting mechanism is activated. Under the action of the lifting mechanism, the lifting plate rises and falls, eventually causing the upper mold base at the bottom of the lifting plate to rise and fall. When the upper mold base moves downward, the wheel spokes are pressed down. The lower mold core of the lower mold base contacts and compacts the wheel spoke mounting surface with the upper mold core of the upper mold base, completing the interference fit with the wheel rim. After the lifting mechanism presses down for two to five seconds, the pressing depth and wheel spoke plane are aligned in place, completing the pressing fit. Then, the upper mold base is reset and raised. The moving frame can move left and right on the worktable, allowing it to move the upper mold base above another set of wheel rim positioning rings. Then, the alignment and pressing operations are completed. At this time, the non-working wheel rim spokes are removed and replaced, waiting for the next operation. This effectively improves work efficiency and ensures that other operations can be performed during the pressure holding process. It allows for the simultaneous loading and unloading of wheel rims on one lower mold base while the wheel rim on another lower mold base is being aligned and pressed, thus improving work efficiency.

[0015] When the corresponding alignment and pressing operations are completed, the lifting rod moves, eventually driving the lifting rod through the through hole into the rim positioning ring, lifting the rim, thus making it easier for workers to remove the workpiece. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1This utility model provides a technical solution: a steel wheel rim straightening and pressing device, including a workbench 1 and two wheel rim positioning rings 4. Two lower mold frame plates 2 are fixedly provided at the top of the workbench 1. A lower mold base 3 is fixedly provided on the top surface of the lower mold frame plate 2. The wheel rim positioning rings 4 pass through the lower mold core of the lower mold base 3 and are set on the upper outer surface of the lower mold base 3. A movable frame 5 is provided on the lower mold base 3. A lifting plate 6 is provided on the movable frame 5. A lifting component is provided on the movable frame 5 to connect the lifting plate 6. An upper mold base 7 corresponding to the lower mold base 3 is fixedly provided at the bottom end of the lifting plate 6. A through hole is opened on the wheel rim positioning rings 4 for the lifting rod 19 to pass through. Two lifting components are provided below the bottom end of the workbench 1. The lifting components are connected to the lifting rod 19.

[0024] See Figure 1 The lifting component is a hydraulic cylinder 8. The hydraulic output rod of the hydraulic cylinder 8 is connected to the lifting plate 6. The inner sides of the four support columns of the moving frame 5 are all provided with vertical sliding grooves 9. The hydraulic cylinder 8 drives the connected lifting plate 6 to rise and fall, and finally drives the upper mold seat 7 at the bottom of the lifting plate 6 to rise and fall. When the upper mold seat 7 moves down, the wheel spokes are pressed down. The lower mold core of the lower mold seat 3 contacts the upper mold core of the upper mold seat 7 to compact and align the wheel spoke mounting surface, and complete the interference fit with the wheel rim. After the lifting component presses down for two to five seconds, the pressing depth and wheel spoke plane are aligned in place, and the pressing is completed.

[0025] See Figure 1-2 The lifting plate 6 is fixed with sliders 10 extending into the vertical slide groove 9 at each of its four corner ends. Each end face of the slider 10 facing the vertical slide groove 9 is provided with a ball bearing 11. Three-quarters of the volume of the ball bearing 11 is movably embedded in the slider 10. When the lifting plate 6 is raised or lowered, the connected slider 10 slides in the vertical slide groove 9, and the ball bearing on the slider 10 rolls on the inner side of the vertical slide groove 9, which can reduce rolling friction and facilitate movement.

[0026] See Figure 1 and Figure 3 The outer walls of the worktable 1 are provided with transverse sliding grooves 12 on both sides. The four support columns of the movable frame 5 are each fixed with a secondary slider 13 located inside the transverse sliding groove 12. Each end face of the secondary slider 13 facing the transverse sliding groove 12 is provided with a secondary ball bearing 14. Three-quarters of the volume of the secondary ball bearing 14 is movably embedded in the secondary slider 13. The outer walls of the worktable 1 are provided with hydraulic cylinders 2 15 on both sides. The hydraulic output rod of the hydraulic cylinders 2 15 is connected to the movable frame 5. The hydraulic cylinders 2 15 drive the movable frame 5 to move left and right, so that the movable frame 5 drives the upper mold base 7 to move above the rim positioning ring 4 of another set. Then, the alignment and pressing operations are completed. The secondary ball bearing 14 slides in the transverse sliding groove 12. The secondary ball bearing 14 can provide support for the movable frame 5 and reduce friction, making it easy to move. When the secondary slider 13 slides to the leftmost and rightmost ends of the transverse sliding groove 12, the secondary slider 13 can no longer move. The upper mold base 7 and the lower mold base 3 are exactly corresponding.

[0027] See Figure 1 and Figure 4 The lifting components include a lifting ring 16 located at the top of the lower mold plate 2. Multiple lifting columns 17 are fixedly mounted on the top of the lifting ring 16. Each lifting column 17 has a facing plate 18 fixedly mounted on its top, facing the rim positioning ring 4. Each facing plate 18 has a lifting rod 19 fixedly mounted on its top. A U-shaped frame 20 is located at the bottom of the worktable 1. A hydraulic cylinder 21 is fixedly mounted on the U-shaped frame 20. A connecting plate 22 is fixedly mounted on the top of the hydraulic output rod of the hydraulic cylinder 21. Two connecting rods 23 penetrating the worktable 1 are fixedly mounted on the top of the connecting plate 22. The top of the connecting rods 23 connects to the bottom of the lifting ring 16. When completing the corresponding alignment and pressing operations, the hydraulic cylinder 21 is controlled to drive the connecting plate 22 and connecting rods 23 to rise. Since the connecting plate 22 is connected to the lifting ring 16, it causes the lifting ring 16, lifting columns 17, facing plates 18, and lifting rods 19 to move. Ultimately, the lifting rods 19 are driven to enter the rim positioning ring 4 through the through-hole, lifting the rim and facilitating the removal of the workpiece by the operator.

[0028] In practice, the two rims are placed inside the rim positioning ring 4, and the two spokes are placed on the lower mold core of the lower mold base 3. Then, the lifting mechanism is activated. Under the action of the lifting mechanism, the lifting plate 6 rises and falls, ultimately causing the upper mold base 7 at the bottom of the lifting plate 6 to rise and fall. When the upper mold base 7 moves downward, the spokes are pressed down. The lower mold core of the lower mold base 3 contacts and compacts the spoke mounting surface with the upper mold core of the upper mold base 7, completing the interference fit with the rim. After the lifting mechanism presses down for two to five seconds, the pressing depth and spoke plane are aligned in place, completing the pressing fit. Then, the upper mold base... 7. After resetting and rising, the moving frame 5 can move left and right on the worktable 1, so that the moving frame 5 drives the upper mold base 7 to move above the rim positioning ring 4 of another set. Then, the adjustment and pressing operations are completed. At this time, the non-working rim spokes are removed and replaced, waiting for the next operation, which effectively improves work efficiency. There are a total of four connecting rods 23. When the corresponding adjustment and pressing operations are completed, the lifting rod 19 moves and finally drives the lifting rod 19 to enter the rim positioning ring 4 through the through hole, lifting the rim, so that the workers can easily take out the workpiece.

[0029] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
