[0037] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0038] Example 1

[0039] like Figures 1-4 As shown in this embodiment, a wheel hub punching device is provided, including a bracket 1, on which a support platform 101 for supporting the wheel hub is fixed; a sliding platform 2 is slidably connected to the bracket 1, and the sliding platform 2 is located above the support platform 101; a plurality of stamping columns 3 are provided on the lower surface of the sliding platform 2; a plurality of discharge holes 4 are opened on the side wall of the support platform 101, and the plurality of discharge holes 4 correspond one-to-one with the plurality of stamping columns 3; wherein, a plurality of first sliders 6 are slidably connected to the side wall of the support platform 101 by springs 5, and an inclined shovel head 601 is provided at the end of each first slider 6 away from the spring 5, and the inclined shovel head 601 extends into the interior of the corresponding discharge hole 4.

[0040] A power column 9 is fixedly connected to the middle of the upper surface of the sliding table 2, and a connector 901 is provided at the upper end of the power column 9.

[0041] The bracket 1 includes a lower end plate 102 and an upper end plate 103. The lower end plate 102 and the upper end plate 103 are connected by multiple guide rods 104. The support platform 101 is fixedly connected to the guide rods 104, and the sliding platform 2 is slidably sleeved on the guide rods 104.

[0042] Preparation phase:

[0043] First, place the wheel hub to be punched on the support platform 101 and ensure that its position is accurate and stable.

[0044] Then, check each component is in normal working condition, especially the sliding platform 2, stamping column 3, discharge hole 4, first sliding block 6 and spring 5, etc.

[0045] Connect the external driving device (such as a pneumatic cylinder, hydraulic cylinder or electric push rod, etc.) to the connector 901 on the upper end of the power column 9, and ensure firm and reliable connection.

[0046] Start and stamping stage:

[0047] Start the external driving device, which begins to apply pressure to the sliding platform 2 downward through the power column 9.

[0048] With the descent of the sliding platform 2, the multiple stamping columns 3 on its lower surface also descend synchronously and contact the predetermined punching position on the hub one by one.

[0049] The stamping column 3 punches the hub under the pressure of the external driving device to form the required hole.

[0050] Waste discharge stage:

[0051] During the punching process, the generated waste (such as metal shavings or small metal pieces) will be discharged through the discharge hole 4 on the side wall of the support platform 101.

[0052] Under each discharge hole 4, there is a first sliding block 6 driven by a spring 5, and the inclined shovel head 601 part of the first sliding block 6 extends into the discharge hole 4.

[0053] When the waste falls into the discharge hole 4, the inclined shovel head 601 will use its inclined angle and the elastic force of the spring 5 to smoothly guide and discharge the waste outside the device, preventing the accumulation or blockage of waste in the discharge hole 4.

[0054] Reset and prepare for the next punching:

[0055] After the punching is completed, the external driving device stops working and pulls the sliding platform 2 back to the initial position through the power column 9.

[0056] At this time, the punching quality can be checked, and necessary adjustments can be made if necessary.

[0057] If there are more hubs to be punched, place the next hub on the support platform 101 and repeat the above process.

[0058] End work:

[0059] When all the hubs are punched, turn off the external driving device and disconnect the power column 9.

[0060] Clean the work area, including metal shavings and impurities on the support platform 101, sliding platform 2, stamping column 3, etc.

[0061] Perform necessary maintenance and upkeep on the equipment to ensure its long-term stable operation.

[0062] Example 2

[0063] like Figures 1-3 As shown, in order to discharge the waste generated by stamping, the lower diameter of the discharge hole 4 is larger than the upper diameter of the discharge hole 4.

[0064] A discharge hopper 8 is fixedly connected to the lower surface of the support platform 101, and the bottom of the discharge hopper 8 is inclined.

[0065] Example 3

[0066] like Figure 1 and Figure 4 As shown, in order to fix the wheel hub on the support platform 101, two clamping components 7 are symmetrically arranged on the support platform 101. Each clamping component 7 includes a second slider 701, which is disposed on the support platform 101. A lead screw 702 is rotatably connected to the support platform 101, and the second slider 701 is engaged with the lead screw 702. A clamping block 703 is provided on the side wall of the second slider 701 for clamping the wheel hub on the support platform 101.

[0067] A docking block 7011 is fixedly connected to the side wall of the second slider 701, and a docking groove 7031 is provided on the side wall of the clamping block 703. The docking block 7011 is movably inserted into the inside of the docking groove 7031.

[0068] A rubber pad 10 is fixedly laid on the end of the clamping block 703 away from the second slider 701.

[0069] Prepare the clamping components:

[0070] On the support platform 101, two clamping components 7 are symmetrically arranged, located on both sides of the hub to be punched.

[0071] Each clamping assembly 7 includes a second slider 701 that is capable of sliding along a track or guide groove on the support platform 101.

[0072] A lead screw 702 is rotatably connected to the support platform 101. This lead screw 702 is engaged with the second slider 701. Therefore, when the lead screw 702 rotates, the second slider 701 will move along the axis of the lead screw 702.

[0073] Install clamping blocks:

[0074] A mating block 7011 is fixedly connected to the side wall of the second slider 701.

[0075] The side wall of the clamping block 703 is provided with a butt joint groove 7031, which is matched with the butt joint block 7011 in shape and size.

[0076] The clamping block 703 is movably inserted into the butt joint groove 7031 of the butt joint block 7011, so that the clamping block 703 can move with the second sliding block 701 and can also be finely adjusted relative to the second sliding block 701.

[0077] Clamping the hub:

[0078] Place the hub to be punched on the support table 101 and ensure its position is correct and stable.

[0079] Then, manually or using a tool to rotate the lead screw 702, so that the second sliding block 701 of the two clamping assemblies 7 approaches the hub at the same time.

[0080] With the movement of the second sliding block 701, the clamping block 703 also gradually approaches the hub and finally tightly clamps the two sides of the hub.

[0081] It should be noted that the end of the clamping block 703 away from the second sliding block 701 is fixedly laid with a rubber pad 10, which can increase the friction between the clamping block 703 and the hub, preventing the hub from moving or sliding during punching.

[0082] Check the clamping effect:

[0083] After clamping is completed, it is necessary to check whether the clamping block 703 firmly clamps the hub.

[0084] The hub can be checked by gently shaking it to ensure that it does not move unexpectedly during punching.

[0085] Punching operation:

[0086] After confirming that the hub has been firmly clamped, the punching operation can be started.

[0087] According to the previously described hub punching work process, start the external driving device and control the sliding table 2 to descend for punching.

[0088] Loosen the clamping:

[0089] After punching is completed, the clamping assembly 7 needs to be loosened to release the hub.

[0090] This is usually achieved by reversing the rotation of the lead screw 702, so that the second sliding block 701 and the clamping block 703 gradually move away from the hub and return to the initial position.

[0091] Take out the hub:

[0092] When the clamp block 703 is completely loosened, the punched hub can be taken out from the support table 101.

[0093] Finally, it should be noted that the above examples are only to illustrate and not limit the technical solutions of the present application, although the present application has been described in detail with reference to the above examples, those skilled in the art should understand that the present application can still be modified or replaced, without departing from the spirit and scope of the present application. Any modification or partial replacement, which should be covered in the scope of the claims of the present application.
