Description
Technical Field
[0001] The utility model relates to the technical field of wheel hub spinning, in particular to an aluminum alloy wheel hub spinning forming device. Background Art
[0002] Spinning, also known as metal spinning technology, is a technology that makes the force point change from point to line to surface through rotation, and at the same time gives a certain pressure in a certain direction to make the metal material deform and flow along this direction to form a certain shape. Here, the metal material must have plastic deformation or flow properties. Spinning is not equivalent to plastic deformation. It is a complex process that combines plastic deformation and flow deformation. When processing aluminum alloy wheels, spinning technology is often used to improve the quality of the wheel and more importantly, improve the durability of the wheel.
[0003] When the spinning machine spins the wheel hub blank, the wheel hub is pressed by a specific tool, and the wheel hub can be quickly spun under heating conditions. However, the outer side of the aluminum alloy wheel hub processed by this method will have circles of grooves, which will affect the subsequent use of the wheel hub. These grooves need to be polished. Secondly, during the polishing process, tiny metal powders will be generated. Due to the changes in the airflow in the processing area, these metal powders will float up and fall on the surface of other workpieces. Finally, the cutting fluid used for dust reduction contains metal particles after use. These metal particles need to be screened out to ensure the reuse of the cutting fluid. Therefore, an aluminum alloy wheel hub spinning forming equipment is proposed to address the above problems. Summary of the invention

[0022] A spin forming device for an aluminum alloy wheel hub comprises a body 1, a rotating shaft 2 is rotatably connected to one side of the body 1, a fixing piece 3 is fixedly connected to one end of the rotating shaft 2 away from the body 1, a telescopic rod 4 is fixedly connected to one side of the body 1 away from the rotating shaft 2, a pressing plate 5 is fixedly connected to one end of the telescopic rod 4, a wheel hub 6 is arranged outside the fixing piece 3, a mechanical arm 7 is fixedly connected to the top of the body 1, a motor 8 is fixedly connected to the other end of the mechanical arm 7, a grinding wheel 9 is fixedly connected to the output end of the motor 8, a bracket 10 is fixedly connected to a place above the telescopic rod 4 on one side of the body 1, a fixing ring 11 is fixedly connected to one end of the bracket 10, a nozzle 12 is arranged inside the fixing ring 11, a connecting pipe 13 is fixedly connected to the top of the nozzle 12, and a drainage hole 14 penetrating the body 1 is arranged near the right side at the bottom end of the body 1.
[0023] A liquid storage box 15 is provided at the bottom end of the body 1, and a filter screen 16 is fixedly connected to the inside of the liquid storage box 15. A straight pipe 17 is fixedly connected to one side of the liquid storage box 15 near the bottom, and a valve 18 is fixedly connected to the end of the straight pipe 17 away from the liquid storage box 15; the shape of the body 1 is C-shaped and arranged symmetrically on the left and right; the fixing ring 11 is a cylindrical hollow tube and is installed in a vertical state; the inside of the liquid storage box 15 is low on the left and high on the right, and the liquid storage box 15 and the body 1 are bolted.
[0024] Working process: When the device is in use, it is supplied with external electricity and chip fluid. A rotating shaft 2 rotates on one side of the machine body 1, and the rotating shaft 2 drives the fixing part 3 to rotate. When the wheel hub 6 needs to be spun, the unprocessed wheel hub 6 is placed on the outside of the fixing part 3, and the telescopic rod 4 is extended to make the pressing plate 5 press against the other side of the wheel hub 6, so that the wheel hub 6 is tightly clamped between the fixing part 3 and the pressing plate 5. The rotating shaft 2 is started to make the wheel hub 6 rotate, and the mechanical arm 7 at the top of the machine body 1 will drive the motor 8 to move until the grinding wheel 9 moves to the outside of the wheel hub 6. The motor 8 is started, and at the same time, the external chip fluid is supplied to the nozzle 12 through the connecting pipe 13, and then sprayed out from the nozzle 12. After the grinding wheel 9 rotates, the groove on the outside of the wheel hub 6 will be polished under the precise control of the mechanical arm 7. The chip fluid sprayed to the wheel hub 6 can cool the wheel hub 6 and also remove the chip fluid caused by grinding. The metal powder generated by grinding is taken away without causing the metal powder to float in the air and finally fall on the surface of other workpieces or equipment. The bracket 10 and the fixing ring 11 fix the nozzle 12. The bolts of the fixing ring 11 can be adjusted to clamp nozzles 12 of different sizes. The cutting fluid sprayed by the nozzle 12 will eventually be discharged from the body 1 through the drainage hole 14 on the body 1 and flow into the liquid storage box 15. A filter screen 16 is provided inside the liquid storage box 15. Since the interior of the liquid storage box 15 is inclined, the cutting fluid entering the liquid storage box 15 will flow to the low-lying side through the filter screen 16 under the action of gravity and be stored therein. When the stored cutting fluid is large, the valve 18 can be opened, and the cutting fluid will be discharged from the liquid storage box 15 through the valve 18 from the straight pipe 17. The filtered cutting fluid can be reused to improve the utilization rate and reduce the cost.
