[0021] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1 - 4 shown, the present invention provides a hexagonal bolt stamping and forming device, including: an underframe 1, a processing table 2 is fixedly connected to the top of the underframe 1, a motor 3 is fixedly connected to the bottom of the processing table 2, and the output end of the motor 3 penetrates through the processing table 2 and extends to the upper side; a stamping assembly 4, the stamping assembly 4 is fixedly connected to the output end of the motor 3, the stamping assembly 4 includes a rotating shaft 401, a first turntable 402 is fixedly connected to the upper end surface of the rotating shaft 401, a plurality of forming dies 403 are uniformly fixedly connected to the top of the first turntable 402, a plurality of fixed rods 404 are fixedly connected to the center of the top of the first turntable 402, a second turntable 405 is fixedly connected between the upper end surfaces of the plurality of fixed rods 404, a plurality of groups of through holes 406 are uniformly opened on the top of the second turntable 405, a sliding rod 407 is slidably connected to the inner surface of each of the plurality of through holes 406, a spring 408 is sleeved on the outer surface of each of the plurality of sliding rods 407, a moving plate 409 is fixedly connected between the lower end surfaces of each group of sliding rods 407, a stamping head 410 is fixedly connected to the bottom of the moving plate 409, the number of the forming dies 403 is equal to that of the stamping heads 410, and the plurality of forming dies 403 and the plurality of stamping heads 410 are in a vertically opposite state respectively, the moving plate 409 is located below the second turntable 405, the plurality of forming dies 403 and the plurality of stamping heads 410 correspond to different stamping models respectively, a force-bearing plate 411 is fixedly connected between the upper end surfaces of each group of sliding rods 407, and the spring 408 is fixedly connected between the top of the second turntable 405 and the bottom of the force-bearing plate 411, legs 6 are fixedly connected to the corners of the top of the processing table 2, a top plate 7 is fixedly connected between the upper end surfaces of the plurality of legs 6, a hydraulic rod 8 is fixedly connected to the top of the top plate 7, the output end of the hydraulic rod 8 penetrates through the top plate 7 and extends to the lower side, and a pressing plate 9 is fixedly connected to the output end of the hydraulic rod 8.

[0023] The effect achieved by the entire Embodiment 1 is that when performing stamping forming processing on hexagon bolts, through the combined use of multiple forming dies 403 and multiple stamping heads 410, it is possible to respectively adapt to a variety of different models of hexagon bolts for quick die change to complete stamping processing. After determining the stamping model, starting the motor 3 can drive the rotation of the rotating shaft 401, and the rotating shaft 401 can drive the first turntable 402, the fixed rod 404, and the second turntable 405 to rotate accordingly. Through the synchronous rotation of the first turntable 402 and the second turntable 405, the forming die 403 and the stamping head 410 required for processing are adjusted to the front side position of the processing table 2. After completing the position adjustment, the raw workpiece is placed into the forming die 403. Starting the hydraulic rod 8 to extend can drive the pressing plate 9 to move downward. After the pressing plate 9 moves downward, it can exert pressure on the force-bearing plate 411, and the force-bearing plate 411 can push the sliding rod 407 to move downward. The sliding rod 407 drives the stamping head 410 to move downward through the connection of the moving plate 409.

When the moving plate 409 is forced to move downward, it will compress the spring 408. After the hydraulic rod 8 completes the stamping processing and moves upward to reset, the resilience of the spring 408 can drive the moving plate 409 to move upward and reset. Through the setting that the multiple forming dies 403 and the stamping heads 410 can be quickly rotated and replaced in position by the drive of the motor 3, the forming die 403 and the stamping head 410 switched to the front side can cooperate with the operation of the hydraulic rod 8 to complete the stamping forming processing of hexagon bolts. The operation of replacing the die is very convenient and fast, meeting the requirement of quickly processing different models of hexagon bolts and effectively improving the processing efficiency.

[0024] Embodiment 2, as Figures 1 - 4 shown, guiding rods 10 are symmetrically and fixedly connected between the processing table 2 and the top plate 7, and the guiding rods 10 slidably penetrate through the pressing plate 9.

[0025] The effect achieved by the entire Embodiment 2 is that when driving the pressing plate 9 to move downward for stamping forming processing through the operation of the hydraulic rod 8, the pressing plate 9 will move along the guiding rod 10. The use of the guiding rod 10 plays a role in guiding and limiting the moving path of the pressing plate 9, ensuring that the pressing plate 9 exerts uniform force on the force-bearing plate 411 to complete stamping, and improving the stability of the equipment operation.

[0026] Working principle: When performing stamping forming processing on hexagon bolts, after determining the stamping model, starting the motor 3 can drive the rotation of the rotating shaft 401. The rotating shaft 401 can drive the first turntable 402, the fixed rod 404, and the second turntable 405 to rotate accordingly. Through the synchronous rotation of the first turntable 402 and the second turntable 405, the forming die 403 and the stamping head 410 required for processing are adjusted to the front side position of the processing table 2. After completing the position adjustment, the raw workpiece is placed into the forming die 403. Starting the hydraulic rod 8 to extend can drive the pressing plate 9 to move downward to press the force-bearing plate 411. The force-bearing plate 411 can push the stamping head 410 to move downward. The stamping head 410 moves downward into the forming die 403 to apply pressure to complete the stamping forming processing of the workpiece. Through the setting that multiple forming dies 403 and stamping heads 410 can quickly rotate and exchange positions driven by the motor 3, the forming die 403 and the stamping head 410 switched to the front side can cooperate with the operation of the hydraulic rod 8 to complete the stamping forming processing of hexagon bolts. The replacement operation of the mold is very convenient and fast, meeting the need for quickly processing hexagon bolts of different models, effectively improving the processing efficiency. When driving the pressing plate 9 to move downward for stamping forming processing through the operation of the hydraulic rod 8, the use of the guiding rod 10 plays a role in guiding and limiting the movement path of the pressing plate 9, ensuring that the pressing plate 9 applies uniform force to the force-bearing plate 411 to complete stamping, and improving the stability of the equipment operation.

[0027] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
