Description

Technical Field

[0001] This utility model relates to the field of top material technology for spinning machines, specifically a top material mechanism for a vertical hub spinning machine. Background Technology

[0002] Spinning, as a special forming method, involves fixing a flat or hollow blank onto the mold of a spinning machine. While the blank rotates with the spindle of the spinning machine, pressure is applied to the blank using a spinning wheel or a pusher to cause localized plastic deformation. The ejector of the spinning machine is an important step in the spinning process, which mainly involves accurately positioning and fixing the blank onto the spindle of the spinning machine for subsequent spinning processing.

[0003] Authorization announcement number CN208787406U discloses a top-feeding mechanism for a vertical wheel hub spinning machine. This device mainly enables effective unloading of wheel hub blanks as needed during the spinning process, and can perform autonomous assisted unloading after spinning. It is easy to operate, reduces the use of external force equipment during unloading, and is conducive to improving the production efficiency and automation level of wheel hub spinning machine products. However, the following defects still exist in actual use of the device:

[0004] The aforementioned patent mainly enables automatic assisted unloading after spinning, which is easy to operate. However, this unloading method simply ejects the blank through the part of the tip that directly contacts the blank. In practice, it is difficult to ensure the dimensional accuracy and form and position tolerance of the spinning process. Furthermore, the ejection pressure should not be too high or too low. In practice, ejecting the blank through the tip will concentrate the pressure at one point, which can easily damage the blank and increase the wear on the blank during ejection, thus increasing the limitations of the spinning machine's ejection operation. Utility Model Content

[0005] The purpose of this utility model is to provide a top material mechanism for a vertical hub spinning machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a top material mechanism for a vertical hub spinning machine, comprising a main shaft, a tapered groove connected to the bottom of the main shaft, a piston cylinder provided at the top of the main shaft, the output end of the piston cylinder extending into the interior of the main shaft and provided with a push rod, a connecting frame provided on the outer side of the push rod, an electric push rod provided on the inner side of the connecting frame, a drive motor provided at the bottom of the push rod, a top material plate provided at the output end of the drive motor, and a top material assembly provided on the inner side of the top material plate.

[0007] Preferably, the top material assembly includes sleeve rods and top material blocks, with four sets of sleeve rods and four sets of top material blocks. The four sets of sleeve rods are installed on the top of the inner side of the top material plate, and the outer side of the sleeve rods is provided with a sliding fit top material block. The output end of the electric push rod is connected to an annular slide groove, and four sets of sliders are slidably arranged on the inner side of the main shaft. The bottom of the sliders is connected to a mounting ring, and the outer side of the mounting ring is hinged with four sets of hinge rods, and the hinge rods are hinged to the top material blocks.

[0008] Preferably, the top plate has through slots at the four corners inside, and the four sets of top blocks pass through the through slots and extend to the outside of the top plate. The four sets of top blocks slide within the through slots, which makes it easier to use the through slots to make the adjustment and movement of the top blocks more stable.

[0009] Preferably, the bottom of the conical groove has an opening, the top plate extends and retracts at the bottom of the conical groove, and a protrusion is provided at the middle position of the bottom of the top plate. The opening allows the top plate to extend and retract within the opening to perform the material-lifting operation.

[0010] Preferably, a telescopic rod is provided on one side of the top of the main shaft body, and the telescopic rod is connected to the annular slide groove to improve the stability of the vertical movement of the annular slide groove.

[0011] Preferably, the main shaft and the tapered groove are integrally connected and interconnected. The push rod extends and retracts vertically inside the main shaft and the tapered groove. The extension and retraction of the push rod drives the top plate to extend and retract vertically to push the wheel hub blank out autonomously.

[0012] Preferably, the drive motor is provided with a protective shell on its outer side and sound-absorbing cotton on its inner side. The bottom of the push rod is connected to the protective shell. The protective shell facilitates the connection between the push rod and the protective shell for lifting and adjustment, so that the drive motor can drive the top plate to rotate.

[0013] The material-lifting mechanism for a vertical hub spinning machine proposed in this utility model has at least the following beneficial effects:

[0014] 1. By setting a top material assembly in the conical groove for easy structural adjustment, the four sets of top material blocks used for top material can be adjusted according to the size of the spinning hub, so that the four sets of top material blocks can be engaged with the outer surface of the hub and make contact. This allows the pushing of the four sets of top material structures to evenly distribute the pressure generated by the billet being ejected, reducing the damage to the billet surface caused by the spinning machine's top material structure, while also reducing the wear of the top tip, thus ensuring the long-term use of the top material structure.

[0015] 2. By setting a drive motor on the ejector end face of the push rod and connecting the drive motor to the ejector plate, four sets of ejector blocks are connected by the hinge rod and the mounting ring to allow the ejector plate to rotate during ejection. The stability of the rotating ejection structure is improved by the guidance of the slider and the annular groove, further dispersing the pressure generated by the ejection of the billet and improving the ejection efficiency of the billet.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The present invention provides an embodiment of a material ejector mechanism for a vertical wheel hub spinning machine, comprising a main shaft 1, a tapered groove 2 connected to the bottom of the main shaft 1, a piston cylinder 3 provided at the top of the main shaft 1, the output end of the piston cylinder 3 extending into the interior of the main shaft 1 and provided with a push rod 7, the main shaft 1 and the tapered groove 2 being integrally connected and interconnected, the push rod 7 extending and retracting vertically within the main shaft 1 and the tapered groove 2, and using the extension and retraction of the push rod 7 to drive the material ejector plate 4 to extend and retract vertically to eject the wheel hub blank autonomously;

[0023] The push rod 7 has a connecting frame 5 on its outer side and an electric push rod 6 on its inner side. The electric push rod 6 is model HTA2500. The bottom of the push rod 7 has a drive motor 8, model DM542-YNN. The output end of the drive motor 8 has a top plate 4, and the inner side of the top plate 4 has a top assembly.

[0024] The top material assembly includes a sleeve rod 9 and a top material block 10. There are four sets of sleeve rods 9 and four sets of top material blocks 10. The four sets of sleeve rods 9 are installed on the top of the inner side of the top material plate 4, and the outer side of the sleeve rod 9 is provided with a sliding fit top material block 10. The output end of the electric push rod 6 is connected to an annular slide groove 11, and four sets of sliders 12 are slidably arranged on the inner side of the main shaft body 1. A telescopic rod is provided on one side of the top of the inner side of the main shaft body 1, and the telescopic rod is connected to the annular slide groove 11 to improve the stability of the vertical movement of the annular slide groove 11. The bottom of the slider 12 is connected to a mounting ring 13, and four sets of hinge rods 14 are hinged on the outer side of the mounting ring 13, and the hinge rods 14 are hinged to the top material block 10.

[0025] The drive motor 8 is provided with a protective shell on the outside and sound-absorbing cotton on the inside of the protective shell. The bottom of the push rod 7 is connected to the protective shell. The protective shell facilitates the connection between the push rod 7 and the protective shell for lifting and adjustment, so that the drive motor 8 can drive the top plate 4 to rotate.

[0026] Example 1, such as Figure 1-4 As shown, through slots 41 are provided at the four corners inside the top plate 4. Four sets of top blocks 10 pass through the through slots 41 and extend to the outside of the top plate 4. The four sets of top blocks 10 slide within the through slots 41. The four sets of through slots 41 on the bottom surface of the top plate 4 cause the top blocks 10 to be distributed and arranged within the through slots 41, and their size can be adjusted simultaneously to adapt to different sizes of wheel hubs and to perform a more uniform ejection pressure.

[0027] Example 2, as Figure 1-4 As shown, the bottom of the conical groove 2 has an opening, and the top plate 4 moves and extends at the bottom of the conical groove 2. A protrusion is provided at the middle position of the bottom of the top plate 4. Through the opening structure of the bottom surface of the conical groove 2, the top plate 4 and the conical groove 2 are sealed to ensure that the main shaft 1 and the conical groove 2 work normally before the material is ejected. With the active ejection of the top plate 4, it can extend downward from the inside of the conical groove 2, thereby autonomously assisting in the unloading of the spun hub.

[0028] Working principle: The vertical hub spinning machine uses a top-feeding mechanism;

[0029] When the wheel hub spinning machine is used for the top material operation, before processing the wheel hub blank, the electric push rod 6 can be activated to drive the annular slide groove 11 and the mounting ring 13 to descend vertically. This causes the mounting ring 13 to drive the four sets of hinge rods 14 to move with the top material block 10, and the top material block 10 extends outward under the descent of the mounting ring 13. This allows the top material block 10 to move horizontally inside the sleeve rod 9 and the through groove 41, and finally allows the top material block 10 to be structurally adjusted according to the size of the blank, so that the top material block 10 can accurately fit the size of the wheel hub blank, laying the foundation for subsequent top material operation.

[0030] During the actual ejection operation, the piston cylinder 3 drives the push rod 7 and the drive motor 8 to eject the ejector plate 4 vertically, and the drive motor 8 drives the ejector plate 4 to rotate as a whole. This causes the ejector plate 4 to drive the ejector block 10, the hinge rod 14 and the mounting ring 13 to rotate respectively. The mounting ring 13 rotates under the guidance of the slider 12 and the annular groove 11. Then, with the downward pressure of the ejector plate 4, the four sets of ejector blocks 10 are driven to fit against the surface of the blank. At the same time, under the action of centrifugal rotation, the processed blank is quickly ejected and the ejection pressure is evenly distributed to avoid damage to the surface of the blank.
