[0025] Example 2: Please refer to Figure 3-Figure 7As shown, the difference between this embodiment and the above embodiment is that the reciprocating translation drive assembly includes a support plate 21, on which two parallel driving shafts 24 are rotatably mounted, a driving unit capable of driving the two driving shafts 24 to rotate synchronously is mounted on one side of the support plate 21, and a translation transmission unit connected between the driving shafts 24 and the moving seat 23 is arranged on the other side of the support plate 21; the translation transmission unit includes a fixed seat 27, a fixed gear 28 and a gear rack 29, and the fixed gear 28 is fixedly mounted on the support plate through the fixed seat 27 21, and the fixed gear 28 is coaxially arranged with the corresponding driving shaft 24, the gear frame 29 is fixedly installed on one end of the driving shaft 24, one end of the gear frame 29 is rotatably installed with a transmission gear 210 meshing and transmittingly connected with the fixed gear 28, the other end of the gear frame 29 is rotatably installed with a rotating shaft 212, one end of the rotating shaft 212 is fixedly installed with a driven gear 211 meshing and transmittingly connected with the transmission gear 210, the other end of the rotating shaft 212 is fixedly installed with a connecting rod 213, one end of the connecting rod 213 is rotatably connected with one side of the moving seat 23; The driving unit includes a motor 22 and two synchronous wheels 25. The motor 22 is fixedly mounted on the outer wall of the support plate 21. The output end of the motor 22 is transmission-connected to one of the driving shafts 24. The two synchronous wheels 25 are respectively fixedly mounted on the ends of the two driving shafts 24, and the two synchronous wheels 25 are transmission-connected via a synchronous belt 26. The lifting drive assembly includes a side plate 31 and a lifting shaft 35. The side plate 31 is fixedly mounted on one side of the support plate 21. A guide groove 33 is provided on the inner side of the side plate 31. The lifting shaft 35 is slidably inserted on the bottom wall of the moving seat 23. A push support plate 32 is fixedly mounted on the top of the lifting shaft 35. A lifting guide block 34 is fixedly mounted on the bottom end of the lifting shaft 35. An elastic pin that is slidably engaged in the guide groove 33 is installed on one side of the lifting guide block 34. The guide groove 33 includes a feed guide groove 331, an upward guide inclined groove 333, a reset guide groove 332 and a downward guide inclined groove 334 that are sequentially connected and arranged, and the feed guide groove 331 and the reset guide groove 332 are both arranged horizontally. During the stamping process, the push support plate 32 is located at the edge of the top surface of the lower stamping die. When a stamping process is completed and it is necessary to push the demoulding and feed the material, the motor 22 drives the drive shaft 24 connected thereto to rotate.

5. A stamping forming device according to claim 2, characterized in that: The lifting drive assembly includes a side plate and a lifting shaft, wherein the side plate is fixedly mounted on one side of the support plate, and a guide groove is provided on the inner side surface of the side plate; The lifting shaft is slidably inserted on the bottom wall of the movable seat, the top end of the lifting shaft is fixedly installed with the push support plate, the bottom end of the lifting shaft is fixedly installed with a lifting guide block, and one side of the lifting guide block is installed with an elastic pin that is slidably engaged in the guide groove.

6. A stamping forming device according to claim 5, characterized in that: The guide groove comprises a feeding guide groove, an upward guide inclined groove, a reset guide groove and a downward guide inclined groove which are connected in sequence, and the feeding guide groove and the reset guide groove are both arranged horizontally.

7. A stamping forming device according to claim 6, characterized in that: The elastic pin comprises a telescopic sleeve, the telescopic sleeve is fixedly mounted on one side of the lifting guide block, a slider is slidably mounted inside the telescopic sleeve, a pressure spring is abutted against the inner end of the slider, a guide shaft is fixedly mounted on the outer end of the slider, and the outer end of the guide shaft is slidably engaged in the guide groove; The depth of the upward guiding inclined groove is greater than the depth of the resetting guiding groove.

8. A stamping forming device according to claim 1, characterized in that: A lifting guide rail is fixedly installed on the inner side wall of the movable seat, and one side of the clamping plate is slidably clamped on the lifting guide rail.

9. A stamping forming device according to claim 1, characterized in that: The clamping drive assembly includes a transmission rack, an intermediate gear and a driven rack. The transmission rack is fixedly installed on the inner edge of the top surface of the push support plate, the driven rack is fixedly installed on the inner edge of the bottom surface of the clamping plate, the intermediate gear is rotatably installed on the inner wall of the moving seat, and the intermediate gear is meshingly connected between the transmission rack and the driven rack.

10. A forming process of a honeycomb sheet, using the stamping forming device according to any one of claims 1 to 9, characterized in that: The specific steps are as follows: First, insert both sides of one end of the long strip honeycomb panel raw material between the corresponding push support plate and the clamping plate, and at the same time, the end of the honeycomb panel raw material is located on the top surface of the lower stamping die, and then the upper stamping die is driven downward by the stamping head to stamp the honeycomb panel raw material on the top surface of the lower stamping die, and then the stamping head drives the upper stamping die upward to reset; At this time, the reciprocating translation driving assembly drives the moving seat to move back and forth along the edge of the top surface of the lower stamping die through a stroke. When the moving seat moves to the left, the lifting driving assembly drives the pushing support plate to move upward to push and demould the honeycomb sheet panel raw material from the lower stamping die, and at the same time, the clamping driving assembly drives the clamping plate downward so that the clamping plate clamps and fixes the demolded honeycomb sheet panel raw material to the top surface of the pushing support plate. Then, as the moving seat continues to move to the left, the moving seat drives the honeycomb sheet panel raw material to continue to move to the left through the clamping and fixing of the pushing support plate and the clamping plate, so that the stamping processing position of the honeycomb sheet panel raw material is staggered with the movement of the lower stamping die, and the unprocessed position moves to the top surface of the lower stamping die. When the moving seat moves to the right, the moving seat drives the pushing support plate and the clamping plate to move to the right and reset, and at this time, the lifting driving assembly drives the pushing support plate to reset downward, and the clamping driving assembly drives the clamping plate to reset upward, so as to loosen the clamping of the honeycomb sheet panel raw material; The upper stamping die is driven downward by the stamping head again to stamp the honeycomb sheet panel raw material on the top surface of the lower stamping die, and this process is repeated until the stamping process of the entire honeycomb sheet panel raw material is completed. Finally, the stamped honeycomb sheet panel and the honeycomb sheet are hot-pressed to form a honeycomb sheet.
