[0053] The present invention will now be described in detail with reference to the accompanying drawings.

[0054] like Figures 1 to 9 As shown, this utility model discloses a nose stud rod bending device, including a machine base 1, a material transfer device 2 disposed on the machine base 1, and a feeding device 3, a twisting device 4, a pressing device 5, and a unloading device 6 used in conjunction with the material transfer device 2. The feeding device 3, the twisting device 4, the pressing device 5, and the unloading device 6 are arranged in a circular array around the material transfer device 2 and on the central axis of the material transfer device 2. The material transfer device 2 rotates relative to the machine base 1 and is used to transfer the workpiece to be processed input by the feeding device 3 to each device for processing. The twisting device 4 is used to twist the workpiece to be processed placed on the material transfer device 2. The pressing device 5 is used to press the workpiece after twisting. The unloading device 6 is used to pick up the workpiece after pressing and unloading.

[0055] During operation, the workpiece to be processed is conveyed to the transfer device 2 via the feeding device 3. Since the transfer device 2 rotates relative to the machine base 1, it facilitates the transfer of the workpiece to the bending device 4, pressing device 5, and unloading device 6 for corresponding processing. The bending device 4 can bend the workpiece placed on the transfer device 2, the pressing device 5 can further press-bend the bent nose stud, and finally, the unloading device 6 picks up the pressed nose stud for automated unloading, achieving fully automated production of nose studs without manual operation and with a high degree of intelligent control. The nose stud is typically made of stainless steel (such as 316L stainless steel) or titanium alloy (such as F136 titanium alloy), materials favored for their durability and hypoallergenicity. The length of the nose stud is typically between 7mm and 20mm, with the specific size depending on the type of nose ring and the wearer's preference. This invention features a compact and rationally designed structure, improving the bending and forming efficiency of nose studs through efficient collaboration between various devices, meeting the needs of mass automated production.

[0056] The feeding device 3 in this embodiment includes a first stand 31, a feeding seat 32 movably disposed on the first stand 31, a feeding cylinder 33 drivenly connected to the feeding seat 32, a material placement groove 34 disposed at one end of the feeding seat 32, a push rod 35 disposed at the other end of the feeding seat 32, and a push cylinder 36 drivenly connected to the push rod 35. The feeding seat 32 is provided with a discharge port 37 at one end near the material placement groove 34, and the material placement groove 34 is connected to the discharge port 37 and the push rod 35 respectively. Specifically, through an external auxiliary feeding mechanism, such as a vibratory feeder, the workpiece to be processed can be placed into the feeding seat 32 through the feeding trough 34. The feeding cylinder 33 drives the feeding seat 32 to move and approach the transfer device 2. Since the feeding trough 34 is connected to the discharge port 37 and the push rod 35 respectively, the push cylinder 36 drives the push rod 35 into the feeding seat 32 and pushes the workpiece to be processed from the discharge port 37 to the transfer device 2, so that the transfer device 2 can rotate and transfer the workpiece to be processed.

[0057] The bending device 4 in this embodiment includes a frame 41, a lifting seat 42 movably mounted on the frame 41, a first lifting cylinder 43 drivenly connected to the lifting seat 42, a bending rod 44 rotatably mounted on the lifting seat 42, and a drive motor 45 drivenly connected to the bending rod 44. The end of the bending rod 44 away from the drive motor 45 is provided with a first bending arm 46 and a second bending arm 47, which are spaced apart. The frame 41 is provided with a first buffer post 48, which stops and abuts against the lifting seat 42. Specifically, the first lifting cylinder 43 drives the lifting seat 42 to move downward until the first bending arm 46 and the second bending arm 47 clamp the workpiece to be processed. Then, the drive motor 45 drives the bending rod 44 to rotate slightly, so that the first bending arm 46 and the second bending arm 47 together bend the workpiece. Finally, the first lifting cylinder 43 drives the lifting seat 42 to move upward, so that the first bending arm 46 and the second bending arm 47 move away from the workpiece. Since the first buffer post 48 is set on the stand 41, when the lifting seat 42 abuts against the first buffer post 48, it can play a good limiting role in the movement range of the lifting seat 42, and can also absorb the impact force to provide a buffering effect, thereby protecting the normal operation of the working parts.

[0058] The bending device 5 of this embodiment includes a base frame 51, a bending assembly 52 inclinedly disposed on the base frame 51, and a positioning assembly 53 used in conjunction with the bending assembly 52. ​​The base frame 51 is provided with an adjusting member 54, which is used to adjust the tilt distance of the bending assembly 52 relative to the base frame 51. The base frame 51 is inclinedly provided with an adjusting groove 55, and the bending assembly 52 is provided with a connecting hole 56 communicating with the adjusting groove 55. Specifically, the adjusting member 54 is a micrometer. Because the micrometer can adjust the tilt distance of the bending assembly 52 relative to the base frame 51, the tilt position adjustment of the bending assembly 52 is more precise, so that the bending assembly 52 can bend and form a workpiece that meets the standard bending angle. An external screw is used to pass through the adjusting groove 55 and connect and fix it to the connecting hole 56, thereby fixing and adjusting the position of the bending assembly 52 with the tilt position adjusted. The positioning assembly 53 supports the position of the workpiece, which facilitates the bending assembly 52 to bend and form the workpiece from top to bottom, resulting in high bending efficiency.

[0059] The bending assembly 52 of this embodiment includes an assembly frame 521, an adjustment assembly 522 movably disposed on the assembly frame 521, a second lifting cylinder 523 drivenly connected to the adjustment assembly 522, and a bending rod 524 disposed on the adjustment assembly 522. The adjustment assembly 522 includes a base plate 5221, a slide rail 5222 disposed on the base plate 5221, an adjustment block 5223 slidably connected to the slide rail 5222, and an adjustment screw 5224 disposed on the base plate 5221. The adjustment screw 5224 is threadedly connected to the adjustment block 5223, and the adjustment block 5223 is connected to the bending rod 524. The assembly frame 521 is provided with a second buffer post 525, which stops and abuts against the base plate 5221. Specifically, before the bending operation, the adjusting screw 5224 is threadedly connected to the adjusting block 5223, and the adjusting block 5223 is slidably connected to the slide rail 5222. Thus, the position of the bending rod 524 can be finely adjusted by the adjusting block 5223 according to the actual working conditions, so that the bending rod 524 is accurately pressed onto the workpiece, and the adjustment effect is good. The second lifting cylinder 523 drives the adjusting component 522 to move up and down. Since the second buffer column 525 is set on the assembly frame 521, when the base plate 5221 abuts against the second buffer column 525, it can play a good limiting role in the movement range of the base plate 5221, and can also absorb the impact force to provide a buffering effect, thereby protecting the normal operation of the working parts.

[0060] The positioning component 53 in this embodiment includes a second stand 531, a positioning seat 532 movably disposed on the second stand 531, a first drive cylinder 533 drivenly connected to the positioning seat 532, and a positioning plate 534 disposed on the positioning seat 532. The first drive cylinder 533 drives the positioning plate 534 to move closer to or away from the bending rod 524 via the positioning seat 532. Specifically, the first drive cylinder 533 drives the positioning seat 532 to move and move closer to the material transfer device 2, thereby using the positioning plate 534 to support the workpiece, so that the bending rod 524 can perform stable bending and forming work on the workpiece.

[0061] The unloading device 6 in this embodiment includes a base frame 61, a translation seat 62 movably disposed on the base frame 61, a second drive cylinder 63 drivenly connected to the translation seat 62, a movable seat 64 movably disposed on the translation seat 62, a third lifting cylinder 65 drivenly connected to the movable seat 64, a gripper cylinder 66 disposed on the movable seat 64, and a gripper member 67 drivenly connected to the gripper cylinder 66. Specifically, the second drive cylinder 63 drives the translation seat 62 to move back and forth, the third lifting cylinder 65 drives the movable seat 64 to move up and down, and the gripper cylinder 66 drives the gripper member 67 to open or close, thereby accurately gripping the workpiece from the transfer device 2 and smoothly transferring it out.

[0062] The material transfer device 2 of this embodiment includes a turntable 21, a cam divider 22 driven and connected to the turntable 21, a servo motor 23 driven and connected to the cam divider 22, and a clamp 24 disposed on the turntable 21. The output end of the servo motor 23 is driven and connected to a drive wheel 25. The input end of the cam divider 22 is provided with a driven wheel 26. A transmission belt 27 is connected between the drive wheel 25 and the driven wheel 26. The machine base 1 is provided with an infrared transmitter 11. The driven wheel 26 is provided with an infrared receiver 28 used in conjunction with the infrared transmitter 11. Several clamps 24 are provided, and the several clamps 24 are connected end to end and arranged around the circumference of the turntable 21. Specifically, preferably, four clamps 24 are provided, which are connected end to end and arranged around the circumference of the turntable 21. The servo motor 23 drives the drive wheel 25 to rotate, and the rotating drive wheel 25 drives the driven wheel 26 to rotate through the transmission belt 27. Since the driven wheel 26 is connected to the input end of the cam divider 22, the output end of the cam divider 22 drives the turntable 21 to rotate. Since the infrared receiver 28 is set on the driven wheel 26, when the driven wheel 26 rotates to a certain position, the infrared light signal emitted by the infrared transmitter 11 is received by the infrared receiver 28. The infrared receiver 28 then sends a detection signal to the control system, which issues a working command to the servo motor 23, causing the servo motor 23 to stop operating. By controlling the turntable 21 to rotate intermittently, it is ensured that the feeding device 3, bending device 4, pressing device 5, and unloading device 6 can each work efficiently on the workpieces placed in the four clamps 24, thereby improving work efficiency and work quality.

[0063] The clamp 24 in this embodiment includes a base 241, a fixed block 242 disposed on the base 241, a fixed clamping arm 243 disposed on the fixed block 242, a guide rail 244 disposed on the base 241, a slider 245 slidably connected to the guide rail 244, a movable block 246 disposed on the slider 245, a movable clamping arm 247 disposed on the movable block 246, a linkage rod 248 disposed on the movable block 246, and a through hole 249 disposed on the fixed block 242. The machine base 1 is provided with a fixed seat 12 and a trigger cylinder 13 disposed on the fixed seat 12. The output end of the trigger cylinder 13 is driven and connected to a trigger rod 14. The movable block 246 passes through the through hole 249 and protrudes out of the fixed block 242 through the linkage rod 248, so that the trigger rod 14 abuts against the linkage rod 248 to control the movable clamping arm 247 to move closer to or away from the fixed clamping arm 243. Specifically, the trigger cylinder 13 drives the trigger rod 14 to move forward, causing the trigger rod 14 to abut against the linkage rod 248. The linkage rod 248 drives the movable block 246 to move horizontally. The movable block 246 slides along the guide rail 244 via the slider 245, thereby controlling the movable clamping arm 247 to move closer to or away from the fixed clamping arm 243, realizing convenient clamping or releasing of workpieces. The structure is ingeniously designed and is very suitable for picking up and placing small workpieces.

[0064] In this embodiment, a stop plate 2410 is provided at the end of the base 241 away from the fixed block 242. The movable block 246 is provided with a return spring 2411 that abuts against the stop plate 2410. A guide plate 2412 is provided on the top of the fixed block 242, and a guide groove 2413 that is slidably connected to the guide plate 2412 is provided on the top of the movable block 246. Specifically, the movable block 246 slides along the guide rail 244 via the slider 245, and the movable block 246 abuts against the stop plate 2410 via the return spring 2411, so as to facilitate the quick reset of the movable clamping arm 247. Moreover, the guide plate 2412 and the guide groove 2413 are slidably connected, providing good guidance and improving the stability of the movable block 246's movement.
