Detailed Implementation

[0027] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0028] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses an automobile wheel hub forging apparatus, such as... Figure 1 As shown, it includes a base 6, an ejection mechanism in the middle of the base 6, columns 5 symmetrically arranged at the upper end of the base 6, an adjustment mechanism inside the columns 5, and a spinning mechanism at the end of the adjustment mechanism; a longitudinal beam 4 is arranged at the upper end of the columns 5, and crossbeams 15 are arranged at the front and rear ends of the side of the longitudinal beam 4, a rolling mechanism is arranged on the front crossbeam 15, and a pressing mechanism is arranged on the rear crossbeam 15.

[0029] The spinning mechanism adjusts its position via an adjustment mechanism. The spinning mechanism includes a spinning wheel shaft 7, a spinning wheel 8, and a mounting frame 25. The spinning wheel 8 is mounted on the mounting frame 25, and the spinning wheel shaft 7 passes through the mounting frame 25 and the spinning wheel 8. The ejection mechanism includes a pushing cylinder 16, a push rod 10, and a lower mold 12. The output end of the pushing cylinder 16 is connected to the push rod 10, and the push rod 10 is connected to the lower mold 12. The pressing mechanism includes an upper pressure plate 13 and a high-pressure cylinder 17. The output end of the high-pressure cylinder 17 is connected to the lower pressure plate. The oscillating rolling mechanism includes an oscillating rolling shaft 14 and an oscillating rolling head 18, which are connected.

[0030] The core mold is initially processed by the ejection mechanism and the pressing mechanism until the core mold completely fills the lower mold 12. The upper pressure plate 13 is lifted and the rotating worktable 11 stops, thus completing the initial processing. The rotating worktable 11 is not connected to the ejector rod 10. The rotating worktable 12 is connected to the motor by the bushing through the synchronous belt to achieve rotation.

[0031] The mandrel is then processed by a rolling mechanism and a spinning mechanism. The spinning wheel 8 extrudes and positions the spokes and rim, while the rolling head 18 extrudes and positions the spokes and rim. Finally, the mandrel is processed into a shaped wheel hub. The wheel hub is processed by the combined use of the ejection mechanism, the pressing mechanism, the spinning mechanism, and the rolling mechanism. The wheel hub is formed without the need for multiple machines to work together, which ensures the processing efficiency of the wheel hub, reduces the manufacturing process and cost, and also reduces the difficulty of subsequent wheel hub machining.

[0032] like Figure 2 As shown, the adjustment mechanism includes a first servo feed mechanism 1, a first lead screw 2, a first slider 3, and a first housing 22. The output end of the first servo feed mechanism 1 is connected to the first lead screw 2. The first slider 3 is sleeved on the first lead screw 2, and one end of the first slider 3 is connected to the first housing 22. The first lead screw 2 passes through the first housing 22.

[0033] The adjustment mechanism also includes a second servo feed mechanism 19, a second lead screw 20, a second slider 21, and a second housing 23, which is connected to the first housing 22. The second servo feed mechanism 19 is mounted on one end of the second housing 23, and its output end is connected to the second lead screw 20. The second lead screw 20 is located inside the second housing 23, and the second slider 21 is sleeved on it. One end of the second slider 21 is connected to a third housing 26, and the end of the second lead screw 20 is located inside the third housing 26. One end of the third housing 26 is connected to a connecting rod 24, which is connected to a mounting bracket 25.

[0034] The first servo feed mechanism 1 and the second servo mechanism can be servo motors. The first servo feed mechanism 1 drives the first lead screw 2 to rotate, thereby causing the first slider 3 to move vertically. Since the first slider 3 is connected to the first housing 22, and the width of the first housing 22 is similar to the width of the column 5, the first slider 3 can be limited, so that the first slider 3 only moves vertically and does not rotate with the first lead screw 2. The first slider 3 drives the first housing 22 to move, thereby driving the second housing 23 to move, so that the spinning mechanism moves in the vertical direction. The second servo mechanism drives the second lead screw 20 to rotate, thereby causing the second slider 21 to move in the horizontal direction. The second housing 23 limits the movement of the second slider 21. The second slider 21 drives the third housing 26 to move, and the third housing 26 drives the connecting rod 24 to move, thereby driving the spinning mechanism to move in the horizontal direction. By adjusting the position of the spinning mechanism through the adjustment mechanism, the spinning mechanism can be arbitrarily adjusted according to the different structures of the wheel hubs to be processed, realizing the processing of various models of wheel hubs.

[0035] The ejection mechanism also includes a pusher cylinder seat 9, on which a pusher cylinder 16 is mounted. Vertical channels are provided on both the lower mold 12 and the rotary table 11, through which the ejector rod 10 passes and connects to the lower mold 12. The pusher cylinder 16 is fixed by the pusher cylinder seat 9, and the pusher cylinder 16 controls the ejector rod 10 to eject the formed part. The ejection mechanism is used to eject the formed part from the base plate and, in conjunction with the pressing mechanism, performs preliminary processing of the core mold.

[0036] The high-pressure cylinder 17 of the pressing mechanism is mounted on the crossbeam 15, and the high-pressure cylinder 17 drives the upper pressure plate 13 to rise and fall. The pressing mechanism is used for the machining and fixing of the wheel hub. The high-pressure cylinder 17 drives the upper pressure plate 13 to rise and fall, and the position of the upper pressure plate 13 is adjusted as needed, thereby machining the core mold.

[0037] The rolling mechanism also includes a drive cylinder 27, the output end of which is connected to the rolling shaft 14. The rolling shaft 14 drives the rolling head 18 to rise and fall. The rolling mechanism is used for the processing and fixing of the wheel hub. The drive cylinder 27 drives the rolling shaft 14 to move, which in turn causes the rolling shaft 14 to drive the rolling head 18 to move. The wheel hub is finally processed through the cooperation of the rolling mechanism and the spinning mechanism. The spinning wheel 8 of the spinning mechanism extrudes and positions the spokes and rim of the outer edge, while the rolling head 18 of the rolling mechanism extrudes and positions the spokes and rim of the inner edge, gradually extruding the thick wall of the mandrel into the shape of the rim and rim.

[0038] The column 5 is a hollow structure, and the adjustment mechanism is located inside the hollow structure of the column 5. The hollow structure of the column 5 provides space for the vertical and horizontal movement of the adjustment mechanism, avoiding motion interference, and at the same time, it cooperates with the first housing 22 to limit the movement of the first slider 3.

[0039] How to use the wheel hub forging device: Plan the shape and size of the wheel hub, make the corresponding lower mold 12, calculate the volume required for the forging part in advance, prepare an aluminum alloy core mold of the same volume, and place the core mold at about 300°C on the lower mold 12 for oscillating and spinning processing.

[0040] The core mold is fixed above the lower mold 12, and the core mold and the lower mold 12 rotate at the same speed. The rotating worktable 11 drives the lower mold 12 to rotate, thereby driving the rotation of the core mold, so that the outer periphery of the core mold can be evenly subjected to spinning pressure. Among them, the upper pressure plate 13 lowers to center the core mold and squeezes the core mold. The rotating worktable 11 is started to drive the core mold to rotate until the core mold completely fills the lower mold 12. Then the upper pressure plate 13 is raised and the rotating worktable 11 stops.

[0041] The oscillating roller 18 is set according to the program requirements and then oscillates and extrudes the mandrel at a designated position. Through the oscillating roller mechanism, the mandrel is oscillated and shaped, giving the formed part the characteristics of wheel spokes and axles. The spokes are connected by a thin-walled skin. After demolding, the skin is cut off to form the spokes, and the axle is machined to create a through hole. The movement paths of the oscillating roller 18 and the spinning roller 8 are set. Finally, the oscillating roller 18 and the spinning roller 8 extrude the spokes and rim of the mandrel. The spinning roller 8 extrudes and positions the outer edge of the spokes and rim, while the oscillating roller 18 extrudes and positions the inner edge of the spokes and rim. Through program control, the thick-walled mandrel is gradually extruded into the shape of the rim and rim. Through the processing of the wheel hub forging device, the mandrel has been processed into the preliminary shape of the wheel hub. The skin on the wheel hub is removed by machining, and after grinding and polishing, the finished wheel hub is obtained.

[0042] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
