Description

Technical Field

[0001] This invention relates to the field of magnesium alloy wheel hub production technology, and more specifically to a magnesium alloy wheel hub production apparatus that facilitates demolding. Background Technology

[0002] Through technological breakthroughs, the weight of a single magnesium alloy wheel can be reduced to 8.7 kg, which is 43% lighter than traditional cast wheels, thus achieving a lightweight effect. Furthermore, based on magnesium and the addition of other elements such as aluminum, zinc, and manganese, it can form corrosion-resistant properties, thereby improving the durability of automobiles. Therefore, the production equipment for magnesium alloy wheels can achieve the production effect by extruding magnesium alloy raw materials into wheel shapes through extrusion molding characteristics. The extrusion molding characteristics can improve the mass production efficiency of magnesium alloy wheels. Thus, the stable manufacturing of magnesium alloy wheels can be ensured through the cooperation of the production equipment. In summary, the inventors have found that the existing production equipment has the following main defects: After the magnesium alloy wheel hub is extruded and molded by the current production equipment, the size of the magnesium alloy wheel hub will be embedded in the force ring of the equipment. Then, due to the influence of the overall diameter of the magnesium alloy wheel hub, it will be difficult to remove it from the force ring for demolding. This means that the current production equipment does not meet the characteristics of easy demolding and reduces the convenience of removing the magnesium alloy wheel hub after production. Ultimately, it will reduce the strength and convenience of the production equipment. Summary of the Invention

The upper end of the base plate is connected to the lower end of the main unit box, and the control panel controls the lifting control body through the main unit box to lower the stamping head to the position of the positioning structure.

[0004] As a further improvement of the present invention, the positioning structure is provided with a locking block, which is welded to the side of the support plate and a support column is connected to the lower layer of one end of the support plate. An anti-slip pad is also provided at the lower end of the support column, and a force-bearing plate is mounted on the side of the support plate to position the force-bearing ring.

[0005] As a further improvement of the present invention, the force-bearing plate is also provided with a slider, which is welded to the left and right sides of the plate body.

[0006] As a further improvement of the present invention, the two sets of support plates of the positioning structure are installed in parallel on the edge of the main unit box by means of support columns and locking blocks, so that the force plate slides in parallel on the inner side of the support plate through the slider and the pull groove, forcing the force ring to carry the magnesium alloy wheel hub away from the lower position of the stamping head, and then the demolding is completed by the demolding device carried by the central plate of the lower layer of the plate body rotating to push out the magnesium alloy wheel hub inside the force ring.

[0007] As a further improvement of the present invention, the base plate is solid and parallel, the control panel of the main unit is touch-sensitive, the lifting control body includes a telescopic rod and a restraining rod to limit the position of the stamping head, and the positioning structure is on the same vertical center line as the stamping head.

[0008] As a further improvement of the present invention, the card block and the support plate form an "L" shape, the support column at one end of the support plate is set in a vertical position and the anti-slip pad at the bottom is made of rubber, the force plate and the force ring are perpendicular to each other and the edge of the force plate and the inner edge of the support plate interpenetrate and contact each other.

[0009] As a further improvement of the present invention, the slider is solid and is symmetrically arranged on the left and right sides of the plate. The groove of the plate is rectangular and hollow. The center block is solid and protruding and is mainly composed of a magnetic block. The limiting rod limits the left and right sides of the center plate. The demolding device is circular and covers the bottom layer of the force ring through the center plate.

[0010] As a further improvement of the present invention, the demolding device is provided with a fusion ring, which covers the edge of the vertical sleeve and the center of the vertical sleeve is penetrated by a screw. The lower end of the screw is connected to a control head and the upper end is provided with a contact plate.

[0011] As a further improvement of the present invention, the vertical sleeve is fused to the center of the central plate through a fusion ring and the screw is set in a vertical orientation. The control head at the lower end of the screw is circular and drives the contact plate to rotate and rise or fall in the force ring.

[0012] As a further improvement of the present invention, the contact plate is also provided with a flexible pad, and a locking bolt is fixed at the center of the lower end of the flexible pad and connected to the inside of the threaded groove and the center of the balance plate through the locking bolt. The balance plate and the flexible pad are parallel to each other.

[0013] As a further improvement of the present invention, the diameter of the flexible pad is the same as the diameter of the balance disc, the locking bolt is set in a vertical position and is detachably connected to the balance disc through a threaded groove, and the balance disc is connected to the upper end of the screw through the lower end of the threaded groove.

[0014] As a further improvement of the present invention, the plate is also provided with a connecting block, the center of which is fixedly connected to the assembly rod, and the lower end of the assembly rod is connected to a positioning block, which completes the connection with the forward and reverse controller.

[0015] As a further improvement of the present invention, the center of the connecting block is penetrated by the assembly rod, the assembly rod is perpendicular to the positioning block and is set in a symmetrical position at the edge of the plate, and the positioning block is interlocked and fixedly connected to the edge of the positive and negative controller.

[0016] As a further improvement of the present invention, the forward and reverse controller is also provided with an overlapping frame, which covers the edge of the loading box and a control block is provided at the center of the lower end of the loading box to control the small drive motor. One end of the small drive motor is provided with a first rotating wheel, and the first rotating wheel carries a belt to drive the second rotating wheel to rotate. The center of the second rotating wheel carries a protrusion that is embedded in the control head.

[0017] As a further improvement of the present invention, the overlapping frame is consistent with the shape of the loading box. The control block in the loading box is equipped with two control buttons to control the forward and reverse rotation of the small drive motor. The first rotating wheel drives the second rotating wheel to rotate through the belt. The protrusion of the second rotating wheel is a square protrusion and is inserted into the control head to drive its rotation.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, with its improved positioning structure, uses two sets of support plates, locking blocks, and support columns to determine the position of the force plate. Then, the force plate uses a force ring to determine the position of the magnesium alloy hub. After the center block at the front end of the force plate is embedded inside the main housing, the alignment accuracy between the force ring and the stamping head is improved. Then, the slider is used to move inside the support plate, exposing the upper part of the force ring in space. Subsequently, the magnesium alloy hub inside the force ring can be ejected by rotating the bottom demolding device, thus achieving the characteristic of easy demolding. This prevents the difficulty in demolding caused by the small operating space due to the upper part being covered by the stamping head and the small gap between the force ring and the magnesium alloy hub. Therefore, it can improve the convenience of magnesium alloy demolding in the production device.

[0019] 2. This invention improves the demolding device by fusing the vertical sleeve with a fusion ring in the center of the central plate, thus enhancing the connection between the two. The screw rotates inside the vertical sleeve, which drives the contact plate to adjust its position up and down. When the contact plate rises, it can push out the magnesium alloy wheel hub inside the force ring to complete the demolding. Conversely, when it falls, it covers the bottom layer of the force ring again, improving its stability in use. Furthermore, the contact plate can contact the surface of the magnesium alloy wheel hub through the flexible pad on the upper layer of the balance plate, preventing surface damage caused by surface scratches during pushing. This prevents damage to the surface of the magnesium alloy wheel hub during demolding.

[0020] 3. Based on the connecting block added to the side of the plate, the present invention allows the newly added assembly rod at the lower end to be assembled through, ensuring the position of the forward and reverse controller at the positioning block position. This allows the second rotating wheel of the forward and reverse controller to be embedded into the control head at the lower end of the screw through the square protrusion. Subsequently, the second rotating wheel can be driven to rotate by the first rotating wheel via a belt. The forward and reverse control of the first rotating wheel by the small drive motor can directly drive the second rotating wheel to rotate in both directions, thereby driving the screw to rotate. Therefore, the intervention of the small drive motor and the first and second rotating wheels can improve the convenience of screw control and avoid the need for manual squatting to manually rotate the control head, thus improving the control convenience of the demolding device.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings: Example 1: Figures 1 to 5 As shown: This invention provides a magnesium alloy wheel hub production apparatus that facilitates demolding. Its structure includes a base plate 1, a main unit box 2, a control panel 3, a lifting control body 4, a stamping head 5, and a positioning structure 6. The upper end of the base plate 1 is connected to the lower end of the main unit box 2, and the control panel 3 controls the lifting control body 4 through the main unit box 2 to lower the stamping head 5 to the position of the positioning structure 6.

[0030] The positioning structure 6 is provided with a locking block 61, which is welded to the side of the support plate 62. A support column 63 is connected to the lower end of one end of the support plate 62. An anti-slip pad 64 is also provided at the lower end of the support column 63. A force plate 65 is mounted on the side of the support plate 62 to position the force ring 66.

[0031] The force-bearing plate 65 is also provided with a slider 651, which is welded to the left and right sides of the plate body 652. The edge of the plate body 652 has a groove 653. The upper center of the plate body 652 is also provided with a center block 654 and a limiting rod 655 is also mounted in the center to position the center plate 656. The center of the center plate 656 is also connected to a demolding device 657.

[0032] Among them, the two sets of support plates 62 of the positioning structure 6 are installed in parallel on the edge of the main unit box 2 by the support column 63 and the locking block 61, so that the force plate 65 slides in parallel on the inner side of the support plate 62 through the slider 651 and the pull groove 653, forcing the force ring 66 to carry the magnesium alloy wheel hub away from the lower position of the stamping head 5. Then, the demolding device 657 carried by the center plate 656 of the lower layer of the plate body 652 rotates to push out the magnesium alloy wheel hub inside the force ring 66 to complete the demolding.

[0033] The base plate 1 is solid and parallel, the control panel 3 of the main unit 2 is touch-sensitive, the lifting control body 4 includes a telescopic rod and a restraining rod to limit the position of the stamping head 5, and the positioning structure 6 is on the same vertical center line as the stamping head 5.

[0034] The card block 61 and the support plate 62 form an "L" shape. The support column 63 at one end of the support plate 62 is set in a vertical position, and the anti-slip pad 64 at the bottom is made of rubber. The force plate 65 and the force ring 66 are perpendicular to each other, and the edge of the force plate 65 interpenetrates and contacts the inner edge of the support plate 62.

[0035] The slider 651 is solid and symmetrically arranged on the left and right sides of the plate 652. The groove 653 of the plate 652 is rectangular and hollow. The center block 654 is solid and protruding and is mainly composed of a magnetic block. The limiting rod 655 limits the left and right sides of the center plate 656. The demolding device 657 is circular and covers the bottom layer of the force ring 66 through the center plate 656.

[0036] The demolding device 657 is provided with a fusion ring 6571, which covers the edge of the vertical sleeve 6572 and the center of the vertical sleeve 6572 is penetrated by a screw 6573. The lower end of the screw 6573 is connected to a control head 6574 and the upper end is provided with a contact plate 6575.

[0037] The vertical sleeve 6572 is fused to the center of the center plate 656 via the fusion ring 6571, and the screw 6573 is set in a vertical orientation. The control head 6574 at the lower end of the screw 6573 is circular in shape, which drives the contact plate 6575 to rotate and rise or fall in the force ring 66.

[0038] The contact plate 6575 is also provided with a flexible pad 5751. A locking bolt 5752 is fixed at the center of the lower end of the flexible pad 5751 and is connected to the inside of the threaded groove 5753 through the locking bolt 5752 and is connected to the center of the balance plate 5754. The balance plate 5754 and the flexible pad 5751 are parallel to each other.

[0039] The diameter of the flexible pad 5751 is the same as that of the balance disc 5754. The locking bolt 5752 is set in a vertical position and is detachably connected to the balance disc 5754 through the threaded groove 5753. The balance disc 5754 is connected to the upper end of the screw 6573 through the lower end of the threaded groove 5753.

[0040] The specific functions and operation procedures of this embodiment are as follows: In this invention, the magnesium alloy wheel hub production device can determine the position of the main unit 2 through the base plate 1. Then, the main unit 2 electrically controls the lifting control body 4 through the control panel 3, causing the stamping head 5 to slide vertically up and down. Therefore, when the stamping head 5 moves downward, it can extrude and form the magnesium alloy wheel hub of the positioning structure 6 to complete the production. Then, the two sets of support plates 62 of the positioning structure 6 are engaged with the side of the main unit 2 through the locking block 61, so that the lower layer of the other end of the support plate 62 can ensure the balance of the inner force plate 65 and the force ring 66 through the support column 63 and the anti-slip pad 64. After the force ring 66 on the force plate 65 installs the magnesium alloy wheel hub, the force plate 65 can receive the push slider 651 in the support plate 62 through the pull groove 653 of the plate body 652. Lateral sliding forces the force-bearing ring 66, carrying the magnesium alloy hub, to move below the stamping head 5. Simultaneously, the front center block 654 is inserted into the main housing 2 for positioning, ensuring that the center of the force-bearing ring 66 overlaps with the center of the stamping head 5 and is on the same vertical center line. After the magnesium alloy hub in the force-bearing ring 66 is extruded by the stamping head 5, the stamping head 5 is reset and disengaged from the force-bearing ring 66 via the lifting control body 4. This allows the plate 652 to be manually moved again via the pull groove 653, causing the slider 651 to slide inside the support plate 62, moving the force-bearing ring 66 outwards and leaving its upper part in a hollowed-out state. Then, the limiting rod 655 of the plate 652 determines the position of the center plate 656, which in turn determines the position of the demolding device 657. The demolding device 657 is positioned below the force ring 66. The demolding device 657 then vertically ejects the magnesium alloy wheel hub from the force ring 66 via a rotating ejection mechanism. This facilitates demolding and improves demolding efficiency after the magnesium alloy wheel hub is produced. The fusion ring 6571 of the demolding device 657 can be welded to fix the vertical sleeve 6572 to the center of the center plate 656. The screw 6573 rotates via the bottom control head 6574, causing the screw 6573 to push the contact plate 6575 upwards through the vertical constraint of the vertical sleeve 6572. Once the contact plate 6575 contacts the bottom layer of the magnesium alloy wheel hub, the screw 6573, controlled by the bolt 6573, can push the magnesium alloy wheel hub out of the force ring 66. This design facilitates demolding, thus improving the efficiency and convenience of the production equipment. The balance disc 5754 of the contact disc 6575 is threaded to the top of the screw 6573 via the lower part of the central threaded groove 5753. Simultaneously, the flexible pad 5751 at the upper level is threaded to the upper half of the threaded groove 5753 via the locking bolt 5752 at the lower center. This allows the flexible pad 5751 to cover the surface of the balance disc 5754. Therefore, by replacing the metal balance disc 5754 with the flexible pad 5751 in contact with the bottom of the magnesium alloy wheel hub, the surface of the magnesium alloy wheel hub can be protected, preventing damage caused by friction between the metal surfaces and improving safety during demolding.

[0041] Example 2: Figures 6 to 7 As shown: This invention provides a magnesium alloy wheel hub production apparatus that facilitates demolding. Its structure includes a connecting block 6521 on the plate 652, the center of the connecting block 6521 being fixedly connected to the assembly rod 6522, and a positioning block 6523 connected to the lower end of the assembly rod 6522, which is used to connect with the forward and reverse controller 6524.

[0042] The center of the connecting block 6521 is penetrated by the assembly rod 6522. The assembly rod 6522 and the positioning block 6523 are perpendicular to each other and are set in a symmetrical position at the edge of the plate 652. The positioning block 6523 is inserted and fixedly connected to the edge of the forward and reverse controller 6524.

[0043] The forward and reverse controller 6524 is also provided with an overlapping frame 5241, which covers the edge of the loading box 5242. The lower center of the loading box 5242 is also provided with a control block 5243 to control the small drive motor 5244. One end of the small drive motor 5244 is provided with a first rotating wheel 5245, and the first rotating wheel 5245 carries a belt 5246 to drive the second rotating wheel 5247 to rotate. The center of the second rotating wheel 5247 carries a protrusion 5248 that is embedded in the control head 6574.

[0044] The overlapping frame 5241 and the loading box 5242 have the same shape. The control block 5243 in the loading box 5242 is equipped with two control buttons to control the forward and reverse rotation of the small drive motor 5244. The first rotating wheel 5245 drives the second rotating wheel 5247 to rotate through the belt 5246. The protrusion 5248 of the second rotating wheel 5247 is a square protrusion and is inserted into the control head 6574 to drive its rotation.

[0045] The specific functions and operation procedures of this embodiment are as follows: In this invention, the newly added connecting block 6521 on the side of the plate 652 allows the assembly rod 6522 at the lower end to pass through, thus assembling the two through a through-engagement method. Then, the positioning block 6523 at the lower end of the assembly rod 6522 connects to the surface edge of the forward / reverse controller 6524, allowing the forward / reverse controller 6524 to be installed on the lower layer of the plate 652 via the assembly rod 6522. Then, the overlapping frame 5241 of the forward / reverse controller 6524 covers the edge of the loading box 5242, allowing the loading box 5242, combined with the assembly rod 6522 of the positioning block 6523, to overlap on the lower layer of the plate 652. Finally, the control block 5243 of the loading box 5242 can... The small drive motor 5244 is electrically controlled, so that when the small drive motor 5244 drives the first rotating wheel 5245 to rotate, the first rotating wheel 5245 drives the second rotating wheel 5247 to rotate via the belt 5246. For this purpose, the protrusion 5248 carried by the second rotating wheel 5247 is embedded in the control head 6574 of the screw 6573. Thus, by controlling the forward and reverse rotation of the small drive motor 5244 through the control block 5243, the control convenience and strength of the demolding device 657 can be improved, avoiding the need for manual rotation by bending over. This enhances the control convenience of the demolding device 657 and improves the ease of use of the production equipment.

[0046] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solutions described in this invention, or by designing similar technical solutions by those skilled in the art under the inspiration of the technical solutions described in this invention, falls within the protection scope of this invention.
