[0029] Automotive wheel stamping equipment is a processing equipment that uses forging machinery to apply pressure to metal blanks, causing them to undergo plastic deformation, thereby obtaining forgings with certain mechanical properties, shapes, and dimensions. Stamping processing is highly efficient and precise, and the processed parts are easy to standardize.

[0030] In related technologies, since the curvature and size of the arc plate are fixed, the arc plate can clamp and fix a matching wheel hub plate, but cannot clamp and fix wheel hub plates of different sizes.

[0031] To address some of the problems in the related technologies, this application provides a stamping device for wheel hub production. When it is necessary to stamp wheel hub plates of different sizes, the position of the positioning rod 24 is adjusted by the sliding component 25. Then, the wheel hub plate is placed on the adjusted positioning rod 24. The first threaded rod 22 is driven to rotate by the motor 21. The rotating first threaded rod 22 pushes the clamping block 23 to move outward of the wheel hub plate through the moving block 221. During the movement, the positioning rod 24 is pressed downward by the extrusion component 27, so that the wheel hub plate on the paddle 241 falls onto the lower mold 15. Then, the four sets of clamping blocks 23 clamp and fix the wheel hub plate on the lower mold 15.

[0032] This application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figures 1-3 This application provides a stamping device for wheel hub production, including a device body 1. The device body 1 includes: a lower die 15 disposed on the top of a workbench 11; a support frame 12 disposed on the top of the workbench 11 and above the lower die 15; a hydraulic rod 13 passing through the support frame 12; an upper die 14 disposed at the bottom of the hydraulic rod 13; and a fixing assembly 2 disposed on the workbench 11. The fixing assembly 2 includes: a motor 21 disposed inside the workbench 11; a first threaded rod 22 disposed at the output end of the motor 21; a moving block 221 sleeved on the outside of the first threaded rod 22 and passing through the workbench 11; a clamping block 23 disposed on the top of the moving block 221; a positioning rod 24 symmetrically disposed on the outside of the lower die 15; a paddle 241 disposed on the outside of the positioning rod 24; an extrusion assembly 27 disposed on the positioning rod 24 and the moving block 221; and a sliding assembly 25 disposed on the positioning rod 24 and the workbench 11.

[0034] In use, the wheel hub plate is placed on the lever 241 of the positioning rod 24. Then, the motor 21 is started, and the motor 21 drives the first threaded rod 22 to rotate. The rotating first threaded rod 22 pushes the clamping block 23 to move outward of the wheel hub plate through the moving block 221. During the movement, the positioning rod 24 is pressed downward by the pressing component 27, so that the wheel hub plate on the lever 241 falls onto the lower mold 15. Then, the four sets of clamping blocks 23 clamp and fix the wheel hub plate on the lower mold 15. After fixing, the hydraulic rod 13 is started, and the hydraulic rod 13 pushes the upper mold 14 to move downward to stamp and shape the wheel hub plate on the lower mold 15. After stamping and shaping, the motor 21 drives the clamping block 23 Reset, positioning rod 24 moves upward through extrusion assembly 27 and pushes paddle 241 to demold the shaped wheel hub on the lower mold 15. When it is necessary to stamp wheel hub plates of different sizes, the position of positioning rod 24 is adjusted according to the size of the wheel hub plate through sliding assembly 25. Then the wheel hub plate is placed on the adjusted positioning rod 24 and fixed by clamping block 23. Finally, the hydraulic rod 13 is used for stamping and shaping, so that the stamping device for wheel hub production can clamp and fix wheel hub plates of different sizes and facilitate the demolding of the shaped wheel hub. This increases the flexibility and practicality of the stamping device for wheel hub production and improves the working efficiency of the stamping device for wheel hub production.

[0035] Specifically, the four sets of motors 21 are synchronously controlled using encoders. An encoder is a common device for measuring the rotational position and speed of a motor. It monitors the motor's motion status in real time through feedback signals, thereby controlling the motor's speed and direction.

[0036] In some embodiments, the clamping block 23 is provided with a groove 231 that matches the wheel hub plate, which limits the wheel hub plate and prevents the wheel hub plate from tilting up and coming off the clamping block 23 when the clamping block 23 is holding the wheel hub plate.

[0037] In some embodiments, the sliding assembly 25 includes: a sliding plate 251 sleeved on the outside of the positioning rod 24, and a sliding groove 252 provided in the worktable 11 to cooperate with the sliding plate 251, so that the positioning rod 24 is slidably connected to the worktable 11, and the positioning rod 24 is pushed to move on the worktable 11 by the sliding plate 251.

[0038] In some embodiments, a second threaded rod 26 is provided on the top of the slide plate 251, and a threaded sleeve 261 is provided on the outer side of the second threaded rod 26. After the positioning rod 24 is adjusted to the correct position, the threaded sleeve 261 is rotated, and the rotating threaded sleeve 261 moves downward and presses against the worktable 11 to press and fix the positioning rod 24.

[0039] In some embodiments, a pressing plate 262 is provided at the bottom of the threaded sleeve 261 to increase the pressing area of ​​the threaded sleeve 261 pressing the worktable 11, thereby increasing the stability of pressing and fixing the positioning rod 24.

[0040] In some embodiments, a limiting plate 263 is provided at the top of the second threaded rod 26 to limit the threaded sleeve 261 and prevent the threaded sleeve 261 from detaching from the second threaded rod 26.

[0041] In some embodiments, the extrusion assembly 27 includes: a first extrusion block 271 disposed at the bottom of the positioning rod 24, and a second extrusion block 272 disposed on one side of the moving block 221 to cooperate with the first extrusion block 271; a spring 273 disposed on the outside of the positioning rod 24 and located at the top of the slide plate 251. When the moving block 221 pushes the clamping block 23 to move, the second extrusion block 272 will squeeze the first extrusion block 271, causing the first extrusion block 271 to drive the positioning rod 24 to move downward. At this time, the spring 273 is in a compressed state. When the moving block 221 is reset, the positioning rod 24 moves upward through the elasticity of the spring 273, thereby pushing the paddle 241 to lift the hub on the lower mold 15 for demolding.

[0042] In some embodiments, the lower mold 15 is provided with a receiving groove 28 for the matching paddle 241. When shaping the smallest model wheel hub plate, the receiving groove 28 is used to receive the downward-moving paddle 241 to avoid affecting the upper mold 14's stamping of the wheel hub plate.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.
