Description
Technical Field
[0001] This utility model relates to the field of rolling forming machine technology, specifically a servo-driven automatic rolling forming machine for wheel hubs and rims. Background Technology
[0002] Wheel hubs and rims are cylindrical metal components that support the tire from the inside and are mounted on the axle. They are also called wheel rims, steel rims, wheels, or tire rims. Wheel hubs come in many varieties depending on their diameter, width, forming method, and material. Flat workpieces can be processed into wheel hubs and rims using a rolling forming machine.
[0003] When flat workpieces are processed by an automatic rolling forming machine, the existing technology generally involves workers feeding the material into the automatic rolling forming machine for processing. When the flat workpiece is processed into a circle, deformation is required. Since the flat workpiece is made of metal, it is prone to breakage or ejection, which may lead to safety accidents. Therefore, a servo-driven automatic rolling forming machine for wheel hubs and rims is proposed. Utility Model Content

A movable plate 404 is threadedly connected to the outer side of the threaded rod 402.
[0026] Specifically, sliding rods 405 are fixed on the front and rear sides of the opposite side of the upper and lower connecting plates 401. The sliding rods 405 are slidably connected inside the movable plate 404. A mounting bracket 406 is fixed on the lower surface of the movable plate 404. A protective frame 407 is fixed on the lower surface of the mounting bracket 406 by bolts.
[0027] Specifically, the lower surface of the protective frame 407 is in contact with the upper surface of the base 1, and a feed inlet is provided through the right side of the protective frame 407. Several second ball bearings are rotatably connected to the top and bottom walls of the feed inlet cavity. The moving plate 404 moves linearly up and down on the outside of the sliding rods 405 on both the front and rear sides.
[0028] It should be noted that after the rolling is completed, the first motor 403 starts, driving the threaded rod 402 to rotate. Then, under the limit of the sliding rods 405 on both the front and rear sides, the moving plate 404 moves upward, driving the protective frame 407 to move upward. The design of the protective mechanism 4 can effectively protect the safety of operators and equipment and prevent accidents during the rolling process.
[0029] Please see Figures 4 to 5 In this embodiment, the rolling assembly 5 includes a support plate 501 fixed to the upper surface of the base 1. A second motor 502 is fixed to the back wall of the support plate 501. A rolling cylinder 503 is rotatably connected to the front of the support plate 501 through a bearing. The outer side of the output shaft of the second motor 502 rotates through the support plate 501 and is fixedly connected to the back of the rolling cylinder 503.

[0030] Specifically, the fixing component includes a connecting frame 504 fixed to the upper side of the back of the rolled cylinder 503, a first electric push rod 505 fixed to the upper surface of the connecting frame 504, the outer side of the output shaft of the first electric push rod 505 sliding through the connecting frame 504 and extending into the interior, a lower pressure block 506 fixed to the outer side of the output shaft of the first electric push rod 505, and a limiting component including a support frame 507 fixed to the upper surface of the base 1.
[0031] Specifically, a second electric push rod 508 is fixed on the upper surface of the support frame 507. The outer side of the output shaft of the second electric push rod 508 slides through the support frame 507 and extends into it. A limit block 509 is fixed on the outer side of the output shaft of the second electric push rod 508. Several first balls 510 are rotatably connected to the lower surface of the limit block 509. The several first balls 510 are evenly distributed on the lower surface of the limit block 509. The support frame 507 is located on the right side of the support plate 501. When the second motor 502 is turned off, the first electric push rod 505 and the second electric push rod 508 are started, driving the lower pressing block 506 and the limit block 509 to move upward. Then, the circular workpiece on the outside of the rolled cylinder 503 is pulled out from the front of the rolled cylinder 503.
[0032] It should be noted that the flat workpiece can be fed into the upper surface of the rolling cylinder 503 through the feed port. Then, the equipment is turned on through the control panel 3. The first electric push rod 505 drives the pressing block 506 to move downward and presses one end of the flat workpiece to fix it on the upper surface of the rolling cylinder 503. Then, the second motor 502 starts, and the output shaft drives the rolling cylinder 503 to rotate. Then, the second electric push rod 508 starts, driving the limit block 509 to move downward. Several first ball bearings 510 press down on one side of the upper surface of the flat workpiece to limit it. Then, the rolling cylinder 503 can roll the flat workpiece into a circle.
[0033] It should be noted that the operation of each component is centrally controlled through the control panel 3, realizing the automation of the rolling process, reducing manual intervention and improving production efficiency. In addition, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing publicly available power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
[0034] The working principle of the above embodiments is as follows:
[0035] In use, the flat workpiece can be fed into the upper surface of the rolling cylinder 503 through the feed port. Then, the device is turned on via the control panel 3. The first electric push rod 505 drives the pressing block 506 downwards, pressing and fixing one end of the flat workpiece onto the upper surface of the rolling cylinder 503. Next, the second motor 502 starts, and its output shaft drives the rolling cylinder 503 to rotate. Then, the second electric push rod 508 starts, driving the limiting block 509 downwards. Several first ball bearings 510 press down on one side of the upper surface of the flat workpiece to limit its movement. The flat workpiece can be rolled into a circle by the rolling cylinder 503. After the circle is rolled, the first motor 403 is started, driving the threaded rod 402 to rotate. Then, under the limit of the sliding rods 405 on the front and rear sides, the moving plate 404 moves upward, driving the protective frame 407 to move upward. Then, the second motor 502 is turned off, and the first electric push rod 505 and the second electric push rod 508 are started, driving the lower pressure block 506 and the limit block 509 to move upward. Then, the circular workpiece on the outside of the rolling cylinder 503 is pulled out from the front of the rolling cylinder 503.
