Abstract
Description
Technical Field
[0001] This utility model relates to the field of adjustment device technology, and in particular to an automatic adjustment device for precision stamping dies. Background Technology
[0002] An automatic adjustment device for precision stamping dies is a device used in precision stamping processes to automatically adjust the position and clearance parameters of the die. Its main structure includes a sensor, a controller, and an adjustment actuator. The sensor is responsible for detecting the state parameters of the die, such as the clearance size and position deviation. The controller receives the signals from the sensor and analyzes and processes them according to preset parameters and algorithms. The adjustment actuator performs actual adjustment actions on the die according to the controller's instructions, using a motor to drive a lead screw to fine-tune the die position.
[0003] The main shortcomings are that the movement of the base plate during stamping affects the adjustment accuracy. Due to the instability of the base plate, the automatic adjustment device is difficult to work accurately based on the initial settings. Furthermore, there is no buffer protection adjustment device. The impact force generated during stamping can easily damage the adjustment device itself, reduce its service life, increase maintenance costs, and also affect the quality stability of the stamped products. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides an automatic adjustment device for precision stamping dies, which aims to improve the problem of existing technology lacking a buffer protection adjustment device, thus causing damage to the adjustment device itself.

Springs are fixedly connected to the opposite surfaces of the two sets of square plates. Square frames are fixedly connected to both sides of the outer wall of the square plates. A connecting block three is rotatably connected to one end of the square frame, and a rotating column is rotatably connected to the middle of the connecting block three.
[0007] As a preferred embodiment of this utility model, the sliding component includes a wheel, which is rotatably connected to a connecting plate one, and a connecting block two is rotatably connected to the right side of the wheel.
[0008] As a preferred embodiment of this utility model, the outer wall of the connecting block two is fixedly connected to a slide rail, and the outer wall of the slide rail is slidably connected to a slider.
[0009] As a preferred embodiment of this utility model, the adjustment component includes a second gear, which is fixedly connected to the output end of the motor, and a second rack is fixedly connected to the outer wall of the pressing plate, which meshes with the second gear.
[0010] As a preferred embodiment of this utility model, the rack is meshed with the gear, and a locking rod is fixedly connected to the outer wall of the base.
[0011] As a preferred embodiment of this utility model, a circular hole is provided in the middle of the rotating disk, and the circular hole engages with the locking rod.

[0014] 2. In this utility model, when the pressing plate is displaced and encounters an impact, the spring absorbs energy and buffers the sudden movement between the square plates. When the impact direction changes, the connecting block three and the rotating column rotate, and the spring changes the force transmission path and angle, dispersing the force from multiple dimensions to prevent the adjustment component from being damaged by excessive force at a single point.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0023] Reference Figures 1 to 5 This utility model provides an embodiment of an automatic adjustment device for precision stamping dies, comprising a base 1, a slot 12 in the middle of the base 1, a connecting rod 4 rotatably connected inside the base 1, a rotating disk 3 fixedly connected to one end of the connecting rod 4, a gear 5 fixedly connected to one end of the connecting rod 4, a connecting plate 7 inside the slot 12, a rack 6 fixedly connected to the right side of the outer wall of the connecting plate 7, and a sliding component rotatably connected to the outer wall of the connecting plate 7. In this structure, the rotation of the rotating disk 3 drives the gear 5 to rotate via the connecting rod 4, which in turn cooperates with the rack 6 to move the connecting plate 7, thereby driving the sliding component to move. Its function is that the position of the sliding component can be adjusted by manually rotating the rotating disk 3, which facilitates subsequent adjustment operations of the die, lays the foundation for precise control of the die state, and improves the flexibility and convenience of adjustment.
[0024] A sliding component is installed inside the slot 12. A pressing plate 18 is provided at the top of the base 1. A motor 15 is installed inside the base 1. An adjustment component is fixedly connected to the output end of the motor 15. A buffer mechanism 2 is fixedly connected to the outer wall of the base 1. The buffer mechanism 2 is used to enhance the overall stability of the mold and prevent the adjustment device from shifting or deforming due to lateral vibration during the stamping process. The slot 12 provides space for the sliding component. The sliding component is connected in a specific way to facilitate manual adjustment of the base plate. The pressing plate 18 is used to directly act on the mold. The motor 15 works with the adjustment component to achieve automatic and precise control. The buffer mechanism 2 can absorb the energy of lateral vibration and prevent the adjustment device from shifting or deforming due to vibration, thus ensuring the stable operation of the mold.
[0025] The sliding assembly includes a wheel 8, which is rotatably connected to a connecting plate 7. A connecting block 9 is rotatably connected to the right side of the wheel 8. A slide rail 10 is fixedly connected to the outer wall of the connecting block 9, and a slider 11 is slidably connected to the outer wall of the slide rail 10. The adjusting assembly includes a gear 14, which is fixedly connected to the output end of the motor 15. In the sliding assembly, the wheel 8 is connected to the connecting plate 7 and the connecting block 9, and can extend flexibly during manual operation, making the adjustment of the base plate effortless and convenient. In the adjusting assembly, the motor 15 drives the gear 14 to rotate, which in turn interacts with the related components of the pressing plate 18 to precisely control the displacement of the pressing plate 18 and achieve automated and precise adjustment of the mold.
[0026] A rack 13 is fixedly connected to the outer wall of the pressing plate 18. The rack 13 meshes with the gear 14. The rack 6 meshes with the gear 5. A locking rod 17 is fixedly connected to the outer wall of the base 1. A round hole 16 is opened in the middle of the rotating disk 3. The round hole 16 engages with the locking rod 17. The rack 13 meshes with the gear 14, converting the power of the motor 15 into the precise displacement of the pressing plate 18, realizing automatic mold adjustment. The rack 6 meshes with the gear 5, causing the rotating disk 3 to rotate and drive the related components to move to adjust the sliding assembly. The locking rod 17 engages with the round hole 16 to lock the position of the rotating disk 3, ensuring stability after manual adjustment.
[0027] The buffer mechanism 2 includes two sets of square plates 201, which are fixedly connected to the outer wall of the base 1. Springs 202 are fixedly connected to the opposite surfaces of the two sets of square plates 201. Square frames 203 are fixedly connected to both sides of the outer wall of the square plates 201. A connecting block 3 204 is rotatably connected to one end of the square frame 203, and a rotating column 205 is rotatably connected to the middle of the connecting block 3 204. The two sets of square plates 201 provide a fixed base for the springs 202. The springs 202 can absorb the impact force during the stamping process. The buffer pressing plate 18 moves abruptly. The rotatable connection between the square frame 203, the connecting block 3 204, and the rotating column 205 can change the force transmission path when the impact direction changes, disperse the impact force in multiple dimensions, protect the adjustment device, and maintain its stable operation.
[0028] Working principle: Rotating the rotating disk 3 drives the connecting rod 4 to rotate, causing gear 5 to rotate. Since gear 5 meshes with rack 6, and rack 6 is located on connecting plate 7, it causes connecting plate 7 to move, thereby pushing out wheel 8, which is rotatably connected to its outer wall. Wheel 8 drives slide rail 10 and slider 11 to move through connecting block 9, realizing the extension of the sliding component, which facilitates easier adjustment and movement of the base plate. After adjustment, the locking rod 17 engages with the central hole 16 of the rotating disk 3 to achieve disk fixation and self-locking, thereby locking the manual adjustment position and enabling automatic adjustment. When the motor 15 starts, the gear 14 at its output end rotates accordingly. Since the gear 14 meshes with the rack 13 on the outer wall of the pressing plate 18, the pressing plate 18 will move up and down according to the rotation of the gear 14 under the drive of the motor 15, precisely adjusting the state of the mold. This design combines manual and automatic adjustment functions. Manual adjustment provides convenience for initial preparation or special situations, while automatic adjustment meets the high-precision control requirements in normal production. The two work together to ensure that the precision stamping mold can operate efficiently and stably, adapt to different stamping process requirements and ensure product quality.
[0029] Furthermore, when the pressing plate 18 is displaced by the adjustment component, if an impact occurs, the spring 202 deforms and absorbs energy between the two sets of square plates 201, buffering the sudden movement of the pressing plate 18. If the impact direction changes, the connecting block 204 and the rotating column 205 at one end of the square frame 203 can rotate, changing the force transmission path and angle. Together with the spring 202, the impact force is dispersed from multiple dimensions, preventing the adjustment component from being damaged due to excessive force at a single point, ensuring stable operation of the device during the stamping process, and extending its service life.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
