The drive end of the stamping drive cylinder 12 is equipped with a stamping movable plate 13 located below the upper fixed plate 112. The lower surface of the stamping movable plate 13 is equipped with a stamping upper die 14. The upper surface of the lower fixed plate 111 is equipped with a stamping lower die 15 that cooperates with the stamping upper die 14.

[0023] Among them, such as Figures 1 to 4 As shown, the automatic feeding assembly 2 includes a feeding machine base installed on the punch press base 11. The feeding machine base is rotatably equipped with an upper feeding roller 21 and a lower feeding roller 22 located directly below the upper feeding roller 21. The feeding machine base is equipped with a servo drive motor 23.

[0024] Furthermore, such as Figures 2 to 3 As shown, the feeding machine includes a fixed base plate 24 screwed and fastened to the punch press base 11. A movable lifting frame 25 is installed on the upper side of the fixed base plate 24. A servo drive motor 23 is installed on the movable lifting frame 25. Two worm gear lifters 26 arranged at left and right intervals are installed on the upper surface of the fixed base plate 24. The drive end of each worm gear lifter 26 is connected to the movable lifting frame 25.

[0025] Furthermore, such as Figures 2 to 4 As shown, the movable lifting frame 25 is provided with a left vertical plate 251 and a right vertical plate 252 that are arranged opposite each other and spaced apart. The left and right ends of the lower feeding roller 22 are respectively rotatably mounted on the left vertical plate 251 and the right vertical plate 252 on the corresponding sides via bearings, and the servo drive motor 23 is connected to the lower feeding roller 22 for drive.

[0026] In addition, such as Figures 2 to 4As shown, a left movable plate 271 is slidably mounted on the upper end of the left vertical plate 251, and a right movable plate 272 is slidably mounted on the upper end of the right vertical plate 252. The left movable plate 271 and the right movable plate 272 are arranged opposite each other. The left and right ends of the upper feeding roller 21 are rotatably mounted on the left movable plate 271 and the right movable plate 272 on the corresponding sides via bearings. A number of left drive cylinders 281 arranged at intervals and moving vertically are installed on the upper end of the left vertical plate 251. The drive end of each left drive cylinder 281 is connected to the left movable plate 271. A number of right drive cylinders 282 arranged at intervals and moving vertically are installed on the upper end of the right vertical plate 252. The drive end of each right drive cylinder 282 is connected to the right movable plate 272.

[0027] Furthermore, the punch press base 11 is equipped with an upper die sensor (not shown in the figure), and the lower die 15 is equipped with a product sensor (not shown in the figure). The intelligent punch press feeding system also includes a controller (not shown in the figure), and the punching drive cylinder 12, servo drive motor 23, upper die sensor, and product sensor are electrically connected to the controller. It should be noted that the upper die sensor can be a reflective photoelectric sensor, the product sensor can be a reflective photoelectric sensor, and the controller is a PLC controller. The aforementioned sensor and controller types do not constitute a limitation on this embodiment; that is, the upper die sensor and product sensor in this embodiment can also be other types of sensors, and the controller in this embodiment can also be other types of controllers.

[0028] It should be noted that the movable lifting frame 25 in this embodiment is installed above the fixed base plate 24 via two worm gear lifters 26. The worm gear lifters 26 in this embodiment can be manual worm gear lifters 26. In use, the operator can adjust the height of the movable lifting frame 25 through the worm gear lifters 26, thereby ensuring that the upper feeding roller 21 and the lower feeding roller 22 can accurately transport the continuous sheet metal to the stamping position.

[0029] The intelligent punch press feeding system of this embodiment will be described in detail below with reference to the specific working process. The working process includes the following steps: Step a: After the upper stamping die 14 and the lower stamping die 15 are closed and the product stamping is completed, the stamping drive cylinder 12 drives the stamping movable plate 13 and the upper stamping die 14 to move upward, so that the upper stamping die 14 moves upward and resets to the initial position. At this time, the upper stamping die 14 moves away from the sensing position of the upper die sensor and the upper die sensor feeds back the signal to the controller. Step b: After the product on the stamping die 15 is removed by manual unloading or automatic unloading by a robotic arm, the product moves away from the sensing position of the product sensor and the product sensor feeds back the signal to the controller. Step c: The controller, in conjunction with the signals fed back by the upper mold sensor and the product sensor, determines that the upper stamping mold 14 and the lower stamping mold 15 are in the open mold state and that the stamped product has been taken away. Then, the controller controls the left drive cylinder 281 and the right drive cylinder 282 to move. The left drive cylinder 281 and the right drive cylinder 282 drive the left movable plate 271 and the right movable plate 272 to move down synchronously, thereby causing the upper feed roller 21 to press down against the continuous sheet material located between the upper feed roller 21 and the lower feed roller 22. Step d: After the upper feeding roller 21 moves down to the position, the controller controls the servo drive motor 23 to move. The servo drive motor 23 drives the lower feeding roller 22 to rotate. At this time, the upper feeding roller 21 and the lower feeding roller 22 cooperate to transport the continuous plate to the upper stamping die 14 and the lower stamping die 15. The servo drive motor 23 can control the continuous plate to be transported at a fixed length. Step e: After the sheet metal is conveyed between the upper stamping die 14 and the lower stamping die 15, the controller controls the servo drive motor 23 to stop moving, and at the same time controls the left drive cylinder 281 and the right drive cylinder 282 to move, so that the upper feeding roller 21 moves up to the initial position. Step f: The controller controls the stamping drive cylinder 12 to move. The stamping drive cylinder 12 drives the stamping movable plate 13 and the stamping upper die 14 to move downward. The stamping upper die 14 and the stamping lower die 15 close and complete the mold closing action. During this process, the stamping upper die 14 and the stamping lower die 15 cooperate to complete the product stamping. Step g: Complete the subsequent product stamping and forming in sequence according to steps a-f above.

[0030] In summary, the intelligent punching machine feeding system of this embodiment has the advantages of novel structural design and high degree of intelligence through the above structural design. It can also realize efficient linkage between punching action and feeding action, which can effectively improve the punching operation efficiency.

[0031] Example 2, as Figures 2 to 3 As shown, the difference between this embodiment 2 and embodiment 1 is that the power output shaft of the servo drive motor 23 is connected to a drive shaft 291, and the drive shaft 291 is rotatably mounted on the left vertical plate 251 through a bearing.

[0032] Among them, the drive shaft 291 is fitted with a drive gear 292 to prevent rotation, and the left end of the lower feed roller 22 is fitted with a driven gear 293 to prevent rotation. The drive gear 292 and the driven gear 293 mesh with each other.

[0033] During the rotation of the lower feed roller 22 driven by the servo drive motor 23, the servo drive motor 23 drives the drive gear 292 to rotate through the drive shaft 291, and the drive shaft 291 drives the lower feed roller 22 to rotate through the gear transmission pair composed of the drive gear 292 and the driven gear 293.

[0034] Example 3, as Figure 2 As shown, the difference between this embodiment 3 and embodiment 1 is that: the left vertical plate 251 and the right vertical plate 252 are respectively provided with vertically extending guide portions 253, and the left movable plate 271 and the right movable plate 272 are respectively provided with vertically extending guide grooves 273. The guide portion 253 of the left vertical plate 251 is inserted into the guide groove 273 of the left movable plate 271, and the guide portion 253 of the right vertical plate 252 is inserted into the guide groove 273 of the right movable plate 272.

[0035] By cooperating with the guide section 253 and the guide groove 273, this embodiment 3 can ensure that the left movable plate 271 and the right movable plate 272 move stably and accurately up and down relative to the corresponding left vertical plate 251 and right vertical plate 252.

[0036] Example 4, as Figures 2 to 4 As shown, the difference between this embodiment 4 and embodiment 1 is that: the fixed base plate 24 is screwed with a number of guide posts 2101 that extend vertically upwards respectively, and the movable lifting frame 25 is screwed with guide sleeves 2102 corresponding to each guide post 2101, and the upper end of each guide post 2101 passes through the center hole of the corresponding guide sleeve 2102.

[0037] During the adjustment of the movable lifting frame 25 by the worm gear jack 26, the guide pair structure composed of the guide column 2101 and the guide sleeve 2102 ensures that the movable lifting frame 25 moves stably and accurately up and down relative to the fixed base plate 24 in this embodiment 4.

[0038] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
