Description

Technical Field

[0001] This utility model relates to the field of retaining ring processing technology, specifically a stamping device for retaining ring processing equipment. Background Technology

[0002] A retaining ring (also known as a snap ring) is a thin-walled, elastic ring-shaped part installed in a shaft groove or hole groove, primarily used for axial positioning. Its core function is to restrict the axial movement of other parts (such as bearings and gears) on the shaft or hole, preventing them from falling off or shifting. Retaining rings are simple in structure, small in size, easy to install and disassemble (requires special snap ring pliers), and inexpensive. They are extremely common standard fastening components in mechanical assembly, widely used in bearing fixing, gear limiting, and other scenarios. Although small, they play an indispensable role in ensuring the axial stability and reliability of components, achieving functions such as anti-loosening and separation.

[0003] Retaining rings are typically formed by stamping steel strips using a stamping press. The uncoiling device of the stamping press feeds the steel strip to the lower end of the stamping device for stamping. To facilitate the collection of the stamped retaining rings, some existing stamping press models are equipped with a lever. When the upper die is reset, the lever is driven by a linkage mechanism to strike the retaining ring, knocking it out of the stamping position. The knocked-out retaining rings are then collected. However, the posture of the retaining rings after stamping is not fixed, so the striking position will vary, which may lead to significant differences in the landing point of the retaining rings, making collection inconvenient. Therefore, we propose a stamping device for retaining ring processing equipment. Utility Model Content

The retaining ring is automatically collected through the magnetic attraction of the square electromagnet. At the same time, the falling position of the retaining ring can be controlled, making collection more convenient. Attached Figure Description

The stamping mechanism 3 includes a rotating seat 31, a connecting shaft 32, a connecting seat 33, and a stamping seat 34. The rotating seats 31 are rotatably connected to the upper ends of the inner walls of the left and right sides of the frame 1 through rotating shafts. A connecting shaft 32 is fixedly connected between the ends of the two rotating seats 31 away from the rotating shaft. A connecting seat 33 is rotatably connected to the middle of the connecting shaft 32. A stamping seat 34 is rotatably connected to the lower end of the connecting seat 33. The upper die 7 is fixed. The lower surface of the stamping base 34 is connected to the front side of the stamping base 34, and a connecting pin is fixedly connected to the lower end of the front side of the stamping base 34. The upper end of the connecting rod 46 is rotatably connected to the outside of the connecting pin. The stamping mechanism 3 also includes a slide rail 35 and a slide groove 36. The slide rail 35 is fixedly connected to the left and right sides of the stamping base 34 respectively. The middle of the inner wall of the left and right sides of the frame 1 is fixedly connected to the slide groove 36. The stamping base 34 and the two slide rails 35 are slidably connected between the two slide grooves 36. The stamping mechanism 3 also includes a drive assembly 37, which includes a large... The machine consists of gear 371, pinion 372, and motor 373. Gear 371 is fixedly mounted on the right end of the right-side rotating shaft. Pinion 372 is rotatably connected to the lower right side of frame 1 via a gear shaft. Gear 371 and pinion 372 are meshed together. A second support frame is fixedly connected to the right side of frame 1, and motor 373 is fixedly connected to the upper end of the second support frame. The gear shaft is fixedly connected to the output shaft of motor 373. The input end of motor 373 is electrically connected to the output end of controller 2. The output shaft of motor 373 drives pinion 372 to rotate. (Motor 373 can be a servo geared motor, which can be precisely controlled by controller 2 to control the number of rotations of motor 373). The small gear 372 drives the large gear 371 to rotate half a turn. The whole assembly consisting of rotating seat 31 and connecting shaft 32 rotates half a turn. Connecting seat 33 descends, driving the whole assembly consisting of stamping seat 34 and slide rail 35 to slide between two slide grooves 36. The upper mold 7 moves down to stamp the steel strip at the upper end of the lower mold 8 to obtain the retaining ring. Then the small gear 372 drives the large gear 371 to continue to rotate half a turn, and the stamping seat 34 resets. Material handling mechanism 4: It includes a bracket 41, a second slide groove 42, a second slide rail 43, a slider 44, a square electromagnet 45, and a connecting rod 46. The bracket 41 is fixedly connected to the left side of the upper surface of the frame 1. The upper end of the bracket 41 is fixedly connected to symmetrically distributed slide grooves 42. The left and right ends of the slider 44 are fixedly connected to the second slide rails 43. The slider 44 and the two slide rails 43 are slidably connected between the two slide grooves 42. The right side of the slider 44 is fixedly connected to the square electromagnet 45, which is located at the left end of the lower mold 8. The middle of the slider 44 rotates... A connecting rod 46 is dynamically connected, with its upper end cooperating with the stamping mechanism 3. A slider 44 is located above the collection port of the material frame 9. A mounting plate 5 is fixedly connected to the left side of the frame 1, and a fiber optic amplifier 6 is fixedly connected to the lower end of the mounting plate 5. The fiber optic amplifier 6 is located above the slider 44 and is bidirectionally electrically connected to the controller 2. When the stamping seat 34 resets, the upper end of the connecting rod 46 is pulled upwards by the stamping seat 34, and the lower end of the connecting rod 46 pulls the slide rail 43 and the slider 44 together to slide to the right between the two slide grooves 42. A square electromagnet 45... The intensity of the light signal detected by the probe of the fiber optic amplifier 6 changes as the fiber optic amplifier 6 detects the position. The fiber optic amplifier 6 then feeds back the position information of the square electromagnet 45 to the controller 2. The controller 2 energizes the square electromagnet 45, making it magnetic. Subsequently, the magnetic square electromagnet 45 moves to the position of the lower mold 8, and the stamped retaining ring is magnetically attracted to the right side of the square electromagnet 45. (The dwell time of the steel strip after stamping is 2-5 seconds after the stamping seat 34 is reset, ensuring that the square electromagnet 45 can be magnetically attracted.) (Retaining ring). When the stamping seat 34 moves down to stamp, the stamping seat 34 synchronously drives the upper end of the connecting rod 46 to move down, thereby resetting the square electromagnet 45. The square electromagnet 45 passes through the fiber optic amplifier 6. When the square electromagnet 45 moves to the left side of the fiber optic amplifier 6, the optical signal value detected by the fiber optic amplifier 6 returns to the value when the square electromagnet 45 is not below the fiber optic amplifier 6, indicating that the square electromagnet 45 has been reset. The square electromagnet 45 loses power and loses its magnetism, and the retaining ring falls down. Due to gravity, the retaining ring falls into the collection port of the material frame 9 and then falls into the interior of the material frame 9.

[0017] It also includes a controller 2, which is located on the upper left side of the frame 1. The controller 2 is bidirectionally electrically connected to the control system of the retaining ring processing equipment, and the input end of the square electromagnet 45 is electrically connected to the output end of the controller 2.

[0018] The working principle of the stamping device of the retaining ring processing equipment provided by this utility model is as follows: This stamping device is set at the rear end of the uncoiling device of the retaining ring processing equipment. The controller 2 is bidirectionally electrically connected to the control system of the retaining ring processing equipment to facilitate the coordination of the operation of each device. The steel strip after uncoiling by the uncoiling device is fed in from the feeding table 10. The pressure plate 11 limits the steel strip to prevent the steel strip from tilting. During stamping, the output shaft of the motor 373 drives the pinion 372 to rotate (the motor 373 can be a servo geared motor, which can be precisely controlled by the controller 2 to control the number of rotations of the motor 373). 2. The large gear 371 rotates half a turn, and the entire assembly consisting of the rotating seat 31 and the connecting shaft 32 rotates half a turn. The connecting seat 33 descends, causing the entire assembly consisting of the stamping seat 34 and the slide rail 35 to slide down between the two slide grooves 36. The upper mold 7 moves down to stamp the steel strip at the upper end of the lower mold 8 to obtain the retaining ring. Then, the small gear 372 drives the large gear 371 to continue rotating half a turn, and the stamping seat 34 resets. When the stamping seat 34 resets, the upper end of the connecting rod 46 is pulled upward by the stamping seat 34, and the lower end of the connecting rod 46 pulls the entire assembly consisting of the slide rail 43 and the slider 44 between the two slide grooves 42. Sliding to the right, the square electromagnet 45 passes the detection position of the fiber optic amplifier 6. The intensity of the light signal detected by the probe of the fiber optic amplifier 6 changes, and the fiber optic amplifier 6 feeds back the position information of the square electromagnet 45 to the controller 2. The controller 2 controls the square electromagnet 45 to be energized. After being energized, the square electromagnet 45 becomes magnetic. Subsequently, the magnetic square electromagnet 45 moves to the position of the lower mold 8. The stamped retaining ring is magnetically attracted to the right side of the square electromagnet 45. (The dwell time of the steel strip after stamping is 2-5 seconds after the stamping seat 34 is reset, ensuring that the square electromagnet 45 can...) (Magnetic adsorption onto the retaining ring). When the stamping seat 34 moves down to stamp, the stamping seat 34 synchronously drives the upper end of the connecting rod 46 to move down, thereby resetting the square electromagnet 45. The square electromagnet 45 passes through the fiber optic amplifier 6. When the square electromagnet 45 moves to the left side of the fiber optic amplifier 6, the optical signal value detected by the fiber optic amplifier 6 returns to the value when the square electromagnet 45 is not below the fiber optic amplifier 6, indicating that the square electromagnet 45 has been reset. The square electromagnet 45 loses power and loses its magnetism, and the retaining ring falls down. Due to gravity, the retaining ring falls into the collection port of the material frame 9 and then falls into the interior of the material frame 9.

[0019] It is worth noting that the controller 2 disclosed in the above embodiments can be a GCAN-PLC-301 general-purpose PLC controller, the fiber amplifier 6 can be an HPF-D028 reflective fiber amplifier, the motor 373 can be an RV063 servo geared motor, and the square electromagnet 45 can be a YR series rectangular electromagnet. The controller 2 controls the operation of the fiber amplifier 6, the square electromagnet 45 and the motor 373 using methods commonly used in the prior art.
