Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wheel rim body processing technology, specifically relating to a wheel rim body expansion and shaping device. Background Technology
[0002] As a key load-bearing component of automobile wheels, the shape accuracy of wheel rims directly affects the stability and safety of the vehicle. During production and maintenance, deformation often needs to be corrected through expansion and shaping. Currently, most mainstream wheel rim shaping equipment uses a fixed mold structure, which has significant limitations: First, it has poor adaptability; one set of equipment can only correspond to a single rim size, and changing the size requires replacing the entire mold, resulting in high costs and low efficiency. Second, the shaping effect is unsatisfactory; most equipment applies force only from the inside or outside, easily leading to uneven stress on the rim, resulting in localized overstretching or incomplete shaping.

[0007] As a preferred embodiment of the above technical solution, the upper movable block is fixedly connected to an upper threaded rod, and the upper end of the upper slider is provided with an upper movable hole for the upper end of the upper threaded rod to move through.

[0013] like Figure 1 As shown, the rim body expansion and shaping device includes a base 1, a column 2 on the base 1, a slide rail 3 on the column 2, an upper slider 4 and a lower slider 5 on the slide rail 3, and a bidirectional lead screw 6 on one side of the column 2. A forward lead screw nut and a reverse lead screw nut are installed on the bidirectional lead screw 6. The forward lead screw nut is fixedly connected to the upper slider 4, and the reverse lead screw nut is fixedly connected to the lower slider 5. The bidirectional lead screw 6 is driven to rotate by a first motor 7. An upper shaping wheel 8 is rotatably mounted on the upper slider 4, and a lower shaping wheel 9 is rotatably mounted on the lower slider 5. The upper shaping wheel 8 is driven to rotate by a second motor 10, and the lower shaping wheel 9 is driven to rotate by a third motor 11. The second motor 10 and the third motor 11 drive the upper shaping wheel 8 and the lower shaping wheel 9 to rotate respectively, while the first motor 7 drives the bidirectional lead screw 6 to rotate, causing the distance between the upper shaping wheel 8 and the lower shaping wheel 9 to gradually increase, thereby achieving the internal support expansion and shaping of the rim body.
[0014] Furthermore, an upper clamping wheel 12 is rotatably mounted on the upper slider 4, and the upper clamping wheel 12 is located above the upper shaping wheel 8. A lower clamping wheel 13 is rotatably mounted on the lower slider 5, and the lower clamping wheel 13 is located below the lower shaping wheel 9. The upper clamping wheel 12 and the lower clamping wheel 13 respectively form a clamping effect on the outside of the rim body, shaping the rim body from the outside.
[0015] Furthermore, the upper clamping wheel 12 is rotatably mounted on the upper movable block 14. A plurality of upper guide rods 15 are fixedly connected to the upper slider 4, each upper guide rod 15 having an upper sliding sleeve fitted onto it. The upper sliding sleeves are fixedly connected to the upper movable block 14. An upper spring 16 is fitted onto each upper guide rod 15, with the upper spring 16 clamping downwards and pressing against the upper movable block 14. The lower clamping wheel 13 is rotatably mounted on the lower movable block 17. A plurality of lower guide rods 18 are fixedly connected to the lower slider 5, each lower guide rod 18 having a lower sliding sleeve fitted onto it. The lower sliding sleeves are fixedly connected to the lower movable block 17. A lower spring 20 is fitted onto each lower guide rod 18, with the lower spring 20 clamping upwards and pressing against the lower movable block 17. The upper spring 16 causes the upper clamping wheel 12 to press against the upper shaping wheel 8, and the lower spring 20 causes the lower clamping wheel 13 to press against the lower shaping wheel 9.
[0016] Furthermore, the upper clamping wheel 12 is detachably connected to a first rotating shaft 21, which rotatably connects to the upper movable block 14; the upper shaping wheel 8 is detachably connected to a second rotating shaft 22, which rotatably connects to the upper slider 4; the lower shaping wheel 9 is detachably connected to a third rotating shaft 23, which rotatably connects to the lower slider 5; and the lower clamping wheel 13 is detachably connected to a fourth rotating shaft 24, which rotatably connects to the lower movable block 17. The detachable connections can be threaded, snap-fit, or other methods. The upper clamping wheel 12, upper shaping wheel 8, lower shaping wheel 9, and lower clamping wheel 13 are replaceable, and their shapes and sizes can be adapted to different specifications of wheel rims.
[0017] Furthermore, the upper movable block 14 is fixedly connected to an upper threaded rod 25, and the upper end of the upper slider 4 is provided with an upper movable hole through which the upper end of the upper threaded rod 25 moves. After the upper end of the upper threaded rod 25 moves through the upper movable hole, it is threadedly connected to an upper adjusting nut 27. The lower movable block 17 is fixedly connected to a lower threaded rod 28, and the lower end of the lower slider 5 is provided with a lower movable hole through which the lower end of the lower threaded rod 28 moves. After the lower end of the lower threaded rod 28 moves through the lower movable hole, it is threadedly connected to a lower adjusting nut. When it is necessary to feed the rim body, the upper adjusting nut 27 and the lower adjusting nut are respectively fitted onto the upper threaded rod 25 and the lower threaded rod 28. By rotating the upper adjusting nut 27 and the lower adjusting nut, the upper movable block 14 and the lower movable block 17 are moved against the spring force, thereby changing the distance between the upper clamping wheel 12 and the upper shaping wheel 8, and the distance between the lower clamping wheel 13 and the lower shaping wheel 9, which facilitates the feeding of the rim body. After feeding is complete, rotate the upper adjusting nut 27 and the lower adjusting nut in the opposite direction to remove them, allowing the upper threaded rod 25 and the lower threaded rod 28 to resume free movement. The upper adjusting nut 27 and the lower adjusting nut are preferably wing nuts for ease of operation.
