Description

Technical Field

[0001] This invention relates to the field of aluminum alloy forged wheel technology, specifically to a multi-station mold frame for aluminum alloy forging. Background Technology

[0002] Forged wheels are manufactured through a forging process. This method minimizes internal porosity and cracks, and often involves multiple forging stages to ensure the removal of material defects, increase internal stress, and improve toughness. This significantly enhances impact resistance and tear resistance at high speeds. The advantages of forged wheels include high strength, enhanced safety, high plasticity, lighter weight, better heat dissipation, and fuel efficiency. Forging is also currently the most advanced wheel manufacturing method. These wheels are approximately 1 to 2 times stronger than cast wheels and 4 to 5 times stronger than ordinary iron wheels, making them more robust and impact-resistant. Their toughness and fatigue strength are also significantly superior to cast wheels, making them less prone to breakage. The only disadvantages are their high price and long production cycle.

[0003] After production, existing wheel hub forging usually requires further finishing using CNC machine tools. Existing CNC machine tools typically use multi-axis machining, and clamping is usually done using triangular chucks. To ensure processing efficiency, multi-station mold sets are usually used for processing.

[0045] A motor is installed at the bottom of the multi-station mold base body 210. A rotating shaft is fixed at the bottom of the machining base 220, and the motor and the rotating shaft are connected by a coupling. The outer wall of the machining base 220 has a transmission groove that matches the outer fixed rack 320. The inner wall of the machining base 220 has a first limiting groove that matches the gear ring 330. The interior of the machining base 220 has a second limiting groove that matches the inner slide cylinder 350.

The horizontal cross-section of the tapered rod 355 is trapezoidal. A connecting rod 4 is fixed on the outer wall of the inner rotating cylinder 360 above the inner guide rod 340. 10. An internal rack 420 is fixed to the other side of the connecting rod 410. An internal gear 430 that meshes with the internal rack 420 is rotatably mounted inside the machining base 220. A side turntable 440 is fixed to the end of the internal gear 430. A side protrusion 450 is fixed to the other end of the side turntable 440. A sliding groove plate 460 is slidably mounted inside the machining base 220. The side protrusion 450 is slidably connected to one side of the outer wall of the sliding groove plate 460.

The cone rods 355 are made of rubber.

[0046] When the wheel hub body 230 is machined on one side, the motor can be started to drive the machining seat 220, which is fixedly connected to the rotating shaft, to rotate around the contact position with the multi-station mold frame body 210. Then, under the meshing action of the outer fixed rack 320, the gear ring 330 can rotate, which in turn drives the inner guide rod 340 fixed on its inner wall to slide on the outer wall of the inner slide cylinder 350. At this time, the inner guide rod 340 can slide inside the first slide groove 351, which allows the inner slide cylinder 350 to slide inside the machining seat 220. Under the connection of the connecting rod 410, the inner rack 420 can slide, which in turn drives the inner gear 430 meshing with it to rotate around the contact position with the inner wall of the machining seat 220. This drives the side turntable 440 fixed at its end to rotate, and the side protrusion 450 fixed at its end can perform circumferential motion. The side protrusion 450 can slide on one side of the slide plate 460, which can drive the slide plate 460 to slide on the inner wall of the processing seat 220. Then, it can push multiple sets of air jet blocks 480 to slide above the wheel hub body 230. At the same time, the air pump 490 can output high-pressure gas to clean the dust adhering to the surface of the wheel hub body 230, which facilitates the cleaning of the wheel hub. When the inner guide rod 340 slides from the first slide groove 351 to the inside of the second slide groove 352, it can push the cone rod 355 to slide inside the second slide groove 352, which can drive the inner rotating cylinder 360 to rotate, which can then drive the toothed cylinder 370 fixed at its top to rotate, which can drive the transmission gear 380 meshing with it to rotate. With the connection between the telescopic seat 390 and the telescopic spring 392, the telescopic rod 391 can drive the wheel hub body 230 to flip over, which can avoid the inconvenience of manual flipping.

[0047] Please refer to this carefully. Figure 4 and Figure 9 The unloading assembly 500 includes an unloading cylinder 510 fixed to the inner wall of the inner slide cylinder 350. Multiple unloading rotating rods 520 rotate at the top of the unloading cylinder 510, and an unloading slider 530 rotates at the other end of each rotating rod 520. An unloading flap 540 slides at the top of the unloading slider 530. A fixed partition 550 is fixed to the inner wall of the processing seat 220 below the hub body 230. The fixed partition 550 is rotatably connected to the multiple unloading flaps 540. An opening is provided below the unloading flaps 540 to connect with the unloading slider 530. The machine tool body 110 has a matching third guide groove, multiple sets of unloading flaps 540 arranged in a ring array, multiple sets of unloading rotating rods 520 arranged in a ring array, multiple sets of hub bodies 230 arranged in a ring array, and multiple sets of placement grooves matching the multiple sets of hub bodies 230 are opened at the top of the machining base 220. A protective door extending into the machine tool body 110 slides on one side, and a push-pull groove matching the protective door is opened inside the machining tool body 110. A control panel is installed on the outer wall of the machining tool body 110.

[0048] As can be seen from the above, when the jet block 480 is in the jet state, the inner slide cylinder 350 can slide on the inner wall of the processing seat 220, which in turn can drive the material discharge cylinder 510 fixed on its inner wall to slide, and then pull multiple sets of material discharge rotating rods 520 that are rotatably connected to the material discharge cylinder 510 to rotate around the contact position with the material discharge slider 530. At this time, the material discharge slider 530 can slide on the bottom end of the material discharge flap 540, which can pull the material discharge flap 540 to rotate around the contact position with the bottom end of the fixed partition 550. At this time, the scrap generated by the wheel hub processing can fall into the interior of the processing seat 220, which facilitates collection. At the same time, the gravitational potential energy of the scrap falling together can prevent the scrap from continuously accumulating and causing blockage.

[0049] In use, by starting the motor, the processing seat 220 can rotate to the top of the multi-station mold frame body 210, allowing the processing cutter head to process the next set of wheel hub bodies 230. During this process, the previous set of wheel hub bodies 230 can rotate with the cooperation of the position adjustment component 300. During this process, the telescopic seat 390 can rotate to drive the telescopic rod 391 to rotate, which in turn can drive the wheel hub body 230 to flip. When the inner guide rod 340 slides into the second slide groove 352 and the fourth slide groove 354, with the cooperation of the cleaning component 400 and the unloading component 500, the air jet block 480 can clean the debris adhering to the surface of the wheel hub body 230. At the same time, the unloading flip plate 540 can automatically flip to collect the debris.
