Description

Technical Field

[0001] The utility model relates to the field of wheel hub processing equipment, in particular to a wheel hub rim rounding device. Background Art

[0002] At present, the spinning process is more and more widely used in the production of light alloy wheels such as aluminum and magnesium. The spinning process is a processing technology with little cutting. After the cast or forged wheel blank undergoes a strong spinning process, the hub and rim parts obtain a large degree of plastic deformation, and the mechanical properties and elongation are greatly improved.

[0003] After the initial forming of the wheel hub Figure 1 As shown, the wheel rim 31 of the hub 3 needs to be further shaped and folded outward. Figure 2 As shown, it includes a frame 1, a lower positioning mold 12 rotating on the frame 1, a moving platform 14 sliding on the frame 1 in the vertical direction, an upper positioning mold 11 rotating on the moving platform 14, a moving seat 13 sliding in the horizontal direction, and a molding wheel 15 rotating on the moving seat 13, and the molding wheel 15 is used to mold the hub rim 31 of the wheel 15.

[0004] When the above-mentioned wheel hub 3 rim 31 rounding device is in use, the upper positioning die 11 moves upward, and the operator places the wheel hub 3 between the upper positioning die 11 and the lower positioning die 12, drives the movable platform 14 downward to make the upper positioning die 11 press the wheel hub 3, and then drives the lower positioning die 12 to drive the wheel hub 3 to rotate, and then moves the movable seat 13 toward one side of the wheel hub 3, and the forming wheel 15 abuts against the wheel hub 3 rim 31 to extrude the wheel hub 31.

[0005] The above-mentioned related technical solutions have the following defects: when the upper positioning mold is lifted, the wheel hub is squeezed by the upper positioning mold, and there is a chance that the wheel hub will move up with the upper positioning mold. When the operator removes the wheel hub, he needs to flip his wrist upward, grab the lower part of the wheel hub and remove the wheel hub from the upper positioning mold. This posture is relatively uncomfortable. Utility Model Content

[0006] In order to enable the operator to remove the wheel hub in a more comfortable posture, the present application provides a wheel hub rim rounding device.

[0007] The present application provides a wheel hub rim rounding device that adopts the following technical solution:

[0008] The wheel hub rim rounding device comprises a frame, an upper positioning mold, a lower positioning mold, a movable seat, a movable platform, a forming wheel, a driving member 1, a driving member 2 and a driving member 3, wherein the lower positioning mold rotates on the frame, the driving member 1 drives the lower positioning mold to rotate, the movable platform slides on the frame in a vertical direction, the driving member 2 drives the movable platform to move, the upper positioning mold rotates on the movable platform, and the driving member 3 is used to drive the movable seat to slide in a horizontal direction, and the forming wheel rotates on the movable seat; it also includes an auxiliary disengagement component for assisting the wheel hub to disengage from the upper positioning mold, the auxiliary disengagement component comprises a driving member 4, a connecting frame and a toggle rod, the connecting frame is fixedly arranged below the movable platform, one end of the toggle rod rotates on the connecting frame, the driving member 4 drives the toggle rod to rotate, and the other end of the toggle rod is located above the wheel hub and is used to press down the wheel rim part of the wheel hub.

[0009] By adopting the above technical solution, when the upper positioning mold moves upward, the wheel hub moves along with the upper positioning mold, and the toggle lever is driven downward by the driving member 4. The end of the toggle lever can be pressed down on the rim of the wheel hub, so that the wheel hub is downwardly separated from the upper positioning mold, and the wheel hub can fall onto the lower positioning mold. The operator can remove the wheel hub from the lower positioning mold. When removing the wheel hub from the lower positioning mold, the wrist is turned down, and the wheel hub can be removed in a more comfortable posture.

[0010] Preferably, the driving member 4 includes a pull rope, a pulley, a counterweight and a receiving platform, the receiving platform is fixedly arranged on the frame, the pulley rotates on the frame, one end of the pull rope is fixed to the toggle rod, and the other end of the pull rope is fixed to the counterweight after passing through the pulley, both ends of the pull rope are located below the pulley, and the counterweight is located directly above the receiving platform;

[0011] When the upper positioning mold moves down to the processing state, there is a distance between the counterweight block and the receiving platform, the pull rope is in a straightened state, and the toggle rod is tilted upward and away from the wheel hub; when the upper positioning mold moves up to the blanking state, the counterweight block abuts against the receiving platform, the pull rope is in a relaxed state, and the toggle rod is tilted downward and is used to press down the rim part of the wheel hub assembled on the upper positioning mold.

[0012] By adopting the above technical solution, when the upper positioning mold moves down to the processing state, one end of the toggle rod fixed by the pull rope will move down with the moving platform. At this time, the other end of the pull rope fixed on the counterweight block will move up. At this time, the pull rope will gradually become straightened. When the counterweight block is separated from the receiving platform, the toggle rod will rise under the action of the gravity of the counterweight block, thereby moving away from the wheel hub, which can reduce the impact of the toggle rod on the wheel hub loading process; when the upper positioning mold moves up to the unloading state, one end of the toggle rod fixed with the pull rope will move up with the moving platform, and the other end of the pull rope fixed on the counterweight block will move down. The counterweight block will move down to abut against the receiving platform. At this time, the pull rope is in a relaxed state. Under the action of the toggle rod's own gravity, the toggle rod will rise and can press down the rim part of the wheel hub assembled on the upper positioning mold.

[0013] Preferably, an abutment block is provided on the side surface of the connecting frame close to the toggle rod, and when the upper positioning mold moves down to the processing state, the toggle rod abuts against the abutment block.

[0014] By adopting the above technical solution, the abutment block is used to limit the upward tilt angle of the toggle lever, reduce the rotation amplitude of the toggle lever, and can extend the service life to a certain extent.

[0015] Preferably, an arc-shaped surface is formed on one end of the toggle rod away from the connecting frame.

[0016] By adopting the above technical solution, the opening of the arc surface can make the end of the toggle rod away from the connecting frame closer to the upper positioning mold. At the same time, it can also increase the contact area between the toggle rod and the hub rim when pressing down the hub rim, thereby better helping the hub to separate from the upper positioning mold.

[0017] Preferably, the toggle rod is never in contact with the upper positioning die.

[0018] By adopting the above technical solution, the toggle rod and the upper positioning mold are always out of contact during the rotation of the toggle rod, which can protect the toggle rod and the upper positioning mold and extend their service life.

[0019] Preferably, one end of the toggle rod away from the connecting frame is covered with a rubber sleeve.

[0020] By adopting the above technical solution, the rubber sleeve has a certain degree of feasible deformation. The rubber sleeve directly abuts against the wheel hub rim instead of the toggle rod, which can avoid direct collision between the toggle rod and the wheel hub rim, reduce noise, and protect the wheel hub.

[0021] Preferably, the second driving member is a first cylinder, which is fixed on the frame. The piston rod of the first cylinder extends vertically downward and is fixed with a mounting ring. The mounting ring is located above the movable platform and is fixed to the movable platform by multiple bolts.

[0022] The technical effects of this utility model are mainly reflected in the following aspects:

[0023] 1. In the process of the upper positioning mold of the utility model moving upward, when the wheel hub moves along with the upper positioning mold, the toggle lever is driven downward by the driving member 4, and the end of the toggle lever can be pressed down on the rim of the wheel hub, so that the wheel hub is downwardly separated from the upper positioning mold and can fall onto the lower positioning mold. The operator can remove the wheel hub from the lower positioning mold. When removing the wheel hub from the lower positioning mold, the wrist is turned downward, and the wheel hub can be removed in a relatively comfortable posture;

[0024] 2. The abutment block of the utility model is used to limit the upward tilt angle of the toggle lever, reduce the rotation range of the toggle lever, and can extend the service life to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 3-6 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0033] The embodiment of the present application discloses a wheel hub rim rounding device.

[0034] Reference Figure 3-Figure 6 The wheel hub rim rounding device of this embodiment includes a frame 1, an upper positioning mold 11, a lower positioning mold 12, a movable seat 13, a movable platform 14, a forming wheel 15, a driving member 1, a driving member 2, and a driving member 3. The lower positioning mold 12 rotates on the frame 1 around the vertical axis. The driving member 1 is used to drive the lower positioning mold 12 to rotate. The movable platform 14 slides on the frame 1 in the vertical direction. The driving member 2 is used to drive the movable platform 14 to move. The upper positioning mold 11 rotates around the vertical axis below the movable platform 14. The upper positioning mold 11 and the lower positioning mold 12 are coaxially arranged. The driving member 3 is arranged on the frame 1 and is used to drive the movable seat 13 to slide in the horizontal direction. The forming wheel 15 rotates on the movable seat 13 around the vertical axis. The forming wheel 15 is used to abut against the rim 31 of the hub 3 to extrude and form the rim 31.

[0035] Reference Figure 3-Figure 6 The first driving member is a motor 16 , which is fixed on the frame 1 . The output shaft of the motor 16 extends vertically upward and is coaxially fixed on the lower positioning die 12 .

[0036] Reference Figure 3-Figure 6 The second driving component is the first cylinder 17, which is fixed on the frame 1. The piston rod of the first cylinder 17 extends vertically downward and is fixed with a mounting ring 171. The mounting ring 171 is located above the movable platform 14 and is fixed to the movable platform 14 by multiple bolts.

[0037] Reference Figure 3-Figure 6 The second driving member is a second cylinder 18, which is fixed on the frame 1. The piston rod of the second cylinder 18 extends toward one side of the axis of the lower positioning mold 12, and the movable seat 13 is fixed on the piston rod of the second cylinder 18.

[0038] Reference Figure 3-Figure 6 The wheel hub rim rounding device of this embodiment also includes an auxiliary disengagement component 2 for assisting the wheel hub 3 to disengage from the upper positioning mold 11. The auxiliary disengagement component 2 includes a driving member 21, a connecting frame 22 and a toggle rod 23. The connecting frame 22 is fixedly arranged below the movable platform 14. One end of the toggle rod 23 rotates on the connecting frame 22. The driving member 21 drives the toggle rod 23 to rotate. The other end of the toggle rod 23 is located above the wheel hub 3 and is used to press down the wheel rim 31 of the wheel hub 3.

[0039] Reference Figure 3-Figure 6During the upward movement of the upper positioning mold 11, the wheel hub 3 moves along with the upper positioning mold 11, and the driving member 21 drives the toggle rod 23 to rotate downward. The end of the toggle rod 23 can be pressed down on the rim 31 of the wheel hub 3, so that the wheel hub 3 is downwardly separated from the upper positioning mold 11, and the wheel hub 3 can fall onto the lower positioning mold 12. The operator can remove the wheel hub 3 from the lower positioning mold 12. When removing the wheel hub 3 from the lower positioning mold 12, the wrist can be turned down, and the wheel hub 3 can be removed in a more comfortable posture.

[0040] Reference Figure 3-Figure 6 The driving part 21 includes a pull rope 211, a pulley 212, a counterweight 213 and a receiving platform 214. The receiving platform 214 is fixed on the frame 1, and the pulley 212 rotates on the frame 1. One end of the pull rope 211 is fixed to the toggle rod 23, and the other end of the pull rope 211 is fixed to the counterweight 213 after passing through the pulley 212. Both ends of the pull rope 211 are located below the pulley 212, and the counterweight 213 is located directly above the receiving platform 214. The weight of the counterweight 213 is greater than the weight of the toggle rod 23.

[0041] Reference Figure 3-Figure 6 When the upper positioning die 11 moves downward to the processing state, there is a distance between the counterweight 213 and the receiving platform 214, the pull rope 211 is in a straightened state, and the toggle lever 23 tilts upward and away from the wheel hub 3. When the upper positioning die 11 moves upward to the blanking state, the counterweight 213 abuts against the receiving platform 214, the pull rope 211 is in a relaxed state, and the toggle lever 23 tilts downward and is used to press down the rim 31 of the wheel hub 3 assembled on the upper positioning die 11.

[0042] Reference Figure 3-Figure 6 When the upper positioning mold 11 moves down to the processing state, one end of the pull rope 211 fixing the toggle rod 23 will move down with the moving platform 14. At this time, the other end of the pull rope 211 fixed to the counterweight block 213 will move up. At this time, the pull rope 211 will gradually straighten. When the counterweight block 213 is separated from the receiving platform 214, the toggle rod 23 will rise under the action of the gravity of the counterweight block 213, thereby moving away from the wheel hub 3, which can reduce the impact of the toggle rod 23 on the wheel hub 3 during the loading process. When the upper positioning mold 11 moves up to the blanking state, one end of the pull rope 211 fixing the toggle rod 23 moves up with the movable platform 14, and the other end of the pull rope 211 fixed to the counterweight block 213 will move down, and the counterweight block 213 will move down to abut against the receiving platform 214. At this time, the pull rope 211 is in a relaxed state, and under the action of the gravity of the toggle rod 23 itself, the toggle rod 23 will tilt downward and be able to press down the rim 31 of the wheel hub 3 assembled on the upper positioning mold 11.

[0043] Reference Figure 3-Figure 6A contact block 221 is provided on the side of the connecting frame 22 near the toggle rod 23. When the upper positioning mold 11 moves down to the processing state, the toggle rod 23 abuts against the contact block 221. The contact block 221 is used to limit the upward tilt angle of the toggle rod 23, reduce the rotation range of the toggle rod 23, and to a certain extent extend the service life.

[0044] Reference Figure 3-Figure 6 The end of the toggle rod 23 away from the connecting frame 22 is provided with an arcuate surface 232. The arcuate surface 232 allows the end of the toggle rod 23 away from the connecting frame 22 to be closer to the upper positioning mold 11. It also increases the contact area between the toggle rod 23 and the rim 31 of the wheel hub 3 when the toggle rod 23 presses down on the rim 31 of the wheel hub 3, thereby better helping the wheel hub 3 to separate from the upper positioning mold 11.

[0045] Reference Figure 3-Figure 6 , the toggle rod 23 never contacts the upper positioning die 11. During the rotation of the toggle rod 23, the toggle rod 23 never contacts the upper positioning die 11, which can protect the toggle rod 23 and the upper positioning die 11 and extend the service life of the toggle rod 23 and the upper positioning die 11.

[0046] Reference Figure 3-Figure 6 The end of the toggle lever 23 away from the connecting frame 22 is covered with a rubber sleeve 231. The rubber sleeve 231 has a certain degree of flexibility. The rubber sleeve 231 directly abuts against the rim 31 of the hub 3 instead of the toggle lever 23, which can prevent the toggle lever 23 from directly colliding with the rim 31 of the hub 3, reduce noise, and protect the hub 3.

[0047] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
