[0016] (3)Beneficial effects Compared with the prior art, the beneficial effects of the present invention are as follows: When it is necessary to adjust the punching position of the workpiece to be punched in the present invention, start the second motor to make the transmission rod and the first bevel gears fixedly arranged on its two segments rotate. The second bevel gears meshing with the two gears can drive the positive and negative lead screws fixedly arranged on their respective sides to rotate synchronously. Thus, the two pairs of second lead screw sleeves acting on the two lead screws can drive the guiding frames fixedly arranged at their inner ends to perform vertical displacement in cooperation with the second guide grooves, thereby indirectly driving the press and the punch assembled at the upper and lower ends of the guide frame in the middle of the guiding frame to perform corresponding displacement adjustments. Then the operator starts the third motor to make the second transmission lead screw rotate. At this time, the third lead screw sleeve acting on the lead screw can drive the above-mentioned assembled guiding frame to perform lateral displacement in cooperation with the third guide groove. The above two adjustment components cooperate with each other to effectively adjust the position of the press and the punch above the workpiece to be punched. After the adjustment is completed, start the press to make the punch punch the workpiece. The punched material will fall into the collection rack along the corresponding punch holes. The weighing module below the collection rack can actually monitor the weight of the punched material. When the preset threshold is reached, a signal will be sent to the controller, and the controller controls the operation of the sound and light alarm to prompt the operator, and the operator can process the material.

[0017] In the present invention, the operator pre-places the workpiece to be punched above the middle of the main body, and then starts the driving component to make the first transmission lead screws connected to both ends rotate. The first lead screw sleeves acting on the two lead screws can drive the clamping main boards fixedly arranged on their respective sides to perform relative displacement in cooperation with the guiding of the first guide rods. During this process, the two first motors at the middle sections of the outer ends of the clamping main boards can be started synchronously to make the rotating rods and gears connected to them rotate. At this time, the upper and lower staggered rack frames respectively arranged on the two gears can drive the clamping sub-boards fixedly arranged on their respective sides to perform relative displacement in cooperation with the guiding of the guide blocks and the first guide grooves. Through the mutual cooperation of the above two clamping components, the four sides of the workpiece to be punched can be stably clamped. Description of the drawings

Then start the driving part 511 to make the first transmission lead screws 512 connected to its two ends rotate. The first lead screw sliders 513 acting on the two lead screws can drive the clamping main boards 52 fixedly installed on them to perform relative displacement in cooperation with the guiding of the first guide rod 514. During this process, the two first motors 531 at the middle sections of the outer ends of the clamping main boards 52 can be started synchronously to make the rotating rods 532 and the gears 533 connected to them rotate.

The second guide grooves 637 and the guide mounting frame 64 are movably and guidingly connected. Guide mounting frames 64 are fixedly arranged on the inner sides of the two pairs of second screw rod sliders 636.

A third screw rod slider 654 is screwed on the periphery of one side of the second transmission screw rod 652, and an assembly guide frame 655 is fixedly arranged on the inner side of the third screw rod slider 654. An activity guiding connection is formed between the assembly guide frame 655 and the third guide grooves 651 arranged on both sides of the middle of the guide mounting frame 64. A press 66 is installed in the middle and above the assembly guide frame 655. A punch 67 is installed at the extending end of the press 66. The collection mechanism 8 includes a moving frame 81, and the moving frame 81 is arranged inside the notch 7. A pulling frame 82 is fixedly arranged on one side of the moving frame 81. Weighing modules 83 are arranged on both sides of the bottom end inside the moving frame 81. A collection frame 84 is placed above the multiple weighing modules 83. When it is necessary to adjust the punching position of the workpiece to be punched, the operator can first start the second motor 631 to make the transmission rod 632 and the first bevel gears 633 fixedly arranged on its two sections rotate. The second bevel gears 634 meshing with the two gears can drive the reverse threaded rods 635 fixedly arranged on them to rotate synchronously. Thus, the two pairs of second screw rod sliders 636 acting on the two screw rods can drive the guide mounting frames 64 fixedly arranged on the inner ends of each pair to cooperate with the second guide grooves 637 to perform a displacement in the A direction, thereby indirectly driving the press 66 and the punch 67 at the upper and lower ends of the assembly guide frame 655 in the middle of the guide mounting frame 64 to perform corresponding displacement adjustments. Then, the operator starts the third motor 653 to make the second transmission screw rod 652 rotate. At this time, the third screw rod slider 654 acting on the screw rod can drive the above-mentioned assembly guide frame 655 to cooperate with the third guide grooves 651 to perform a displacement in the B direction. The two adjusting components cooperate with each other to effectively adjust the positions of the press 66 and the punch 67 above the workpiece to be punched. After the adjustment is completed, start the press 66 to use the punch 67 to punch the workpiece. The punched material will fall into the collection frame 84 along the corresponding punch hole 3.The weighing module 83 below the collection rack 84 can actually monitor the weight of the punched materials. When the preset threshold is reached, it will send a signal to the controller, and the controller controls the operation of the sound and light alarm to prompt the personnel, and the personnel can process the materials.

[0024] Working principle: The staff pre-place the workpiece to be punched (processed sheet) in the middle above the main body 1, and then start the driving component 511 to rotate the first transmission screw rod 512 connected to both ends thereof (two motors are provided in the driving component 511 to achieve independent control of the two first transmission screw rods 512). The first screw sleeve 513 acting on the two screw rods can drive the clamping main board 52 fixed thereto to perform relative displacement in cooperation with the guiding of the first guide rod 514. During this process, two first motors 531 in the middle of the outer ends of the clamping main board 52 can be started synchronously to rotate the rotating rods 532 and gears 533 connected thereto respectively. At this time, the upper and lower staggered rack frames 534 provided on the two gears 533 can drive the clamping sub-boards 535 fixed thereto to perform relative displacement in cooperation with the guiding of the guide blocks 536 and the first guide grooves 537. Through the mutual cooperation of the above two clamping components, the four sides of the workpiece to be punched can be stably clamped and a small amount of up and down movement can be achieved (the moving direction is Figure 2(referenced as such), where the clamping stroke can be achieved by setting corresponding pressure trigger switches on the surface of the components in contact with the processed sheet metal. The above trigger is prior art and will not be elaborated here. At the same time, the corresponding clamping stroke is obtained by calculating the rotation amounts of the motors in the driving component 511 and the first motor 531, and then the dimensional parameters of the currently clamped processed sheet metal are calculated. Subsequently, when it is necessary to adjust the punching position of the sheet metal to be processed, on the one hand, the second motor 631 can be started to make the transmission rod 632 and the first bevel gears 633 fixedly arranged on its two peripheries rotate. The second bevel gears 634 meshing with the two gears can drive the left - right lead screws 635 fixedly arranged on them to rotate synchronously. Thus, the two pairs of second lead screw sleeves 636 acting on the two lead screws can drive the guiding frames 64 fixedly arranged at their inner ends to perform vertical displacement in cooperation with the second guide grooves 637, thereby indirectly driving the press 66 and the punch 67 at the upper and lower ends of the guiding frame 655 assembled in the middle of the guiding frame 64 to perform corresponding displacement adjustment. Then, the operator starts the third motor 653 to make the second transmission lead screw 652 rotate. At this time, the third lead screw sleeve 654 acting on the lead screw can drive the above - mentioned assembled guiding frame 655 to perform lateral displacement in cooperation with the third guide groove 651. The above two adjustment components cooperate with each other to effectively adjust the positions of the press 66 and the punch 67 above the workpiece to be punched. On the other hand, the two motors in the driving component 511 can be adjusted to move the processed sheet metal up and down in a short range. After the adjustment is completed, the press 66 is started to make the punch 67 punch the workpiece. For the specific stamping method of multiple holes, please refer to the control method and will not be elaborated here. The punched materials will fall into the collection rack 84 along the corresponding punching holes 3. The weighing module 83 below the collection rack 84 can actually monitor the weight of the punched materials. When the preset threshold is reached, a signal will be sent to the controller, and the controller controls the operation of the sound and light alarm to prompt the operator, and the operator can process the materials. Embodiment

[0025] A control method for a multi - hole punching device, the method comprising: As Figure 2 shown, the distribution of the punching holes 3 is closely arranged horizontally and sparsely arranged vertically. During the actual processing and production process, the horizontally closely arranged punching holes 3 can meet the horizontal arrangement accuracy of the holes on the sheet metal, that is, the sheet metal does not need to be horizontally shifted left and right to adjust the stamping position. The longitudinal centerlines corresponding to the preset processing holes are all preset and coincide with the longitudinal centerlines of the multiple punching holes on the main body 1; Similarly, theoretically, the longitudinal spacing of the punching holes 3 can be reduced, so as to meet the longitudinal arrangement accuracy of the hole positions on the plate, and further enable the plate not to move up and down to adjust the stamping position. However, in the actual production process, the punching holes 3 that are closely arranged both horizontally and vertically make the top plate of the main body 1 unable to provide sufficient stamping stiffness, that is, there is a risk of abnormal deformation due to insufficient rigidity in the top plate of the main body 1 during the stamping process. Therefore, the distribution of the punching holes 3 is designed to be closely arranged horizontally and sparsely arranged longitudinally, and the clamping main board 52 is driven by the driving component 511 to drive the processed plate to move up and down for the alignment operation of the longitudinal hole positions.

[0026] Step S1: In response to the start command triggered by the operator, fix the processed plate through the clamping mechanism 5, and calculate the corresponding size parameters of the processed plate based on the clamping stroke of the driving component in the clamping mechanism 5. Specifically, it is calculated through the rotation amounts of the two motors in the first motor 531 and the driving component 511 from the initial position to the clamping position. Step S2: Query the position parameters of multiple processing hole positions in the equipment operation library based on the size parameters. Step S3: Classify multiple processing hole positions horizontally based on the array parameters of multiple punching holes 3 on the main body 1 and the position parameters of multiple processing hole positions, so as to obtain multiple horizontal hole groups. Among them, the array parameters include the horizontal spacing and the longitudinal spacing of multiple punching holes 3. Secondly, the specific operation of horizontally classifying multiple processing hole positions is as follows: Step S31: Calculate the horizontal spacing values between multiple processing hole positions based on the position parameters of multiple processing hole positions, and classify the multiple processing hole positions with the horizontal spacing value being an integer multiple of the horizontal spacing in the matrix parameters into one horizontal hole group.

[0027] Step S4: Construct the shortest processing path corresponding to each horizontal hole group through the Dijkstra algorithm, and mark the endpoints corresponding to each shortest processing path. Step S5: Traverse all the series paths corresponding to multiple endpoints, and generate the processing sequence corresponding to multiple shortest processing paths based on the shortest series path. Among them, the series path is the theoretical connection path between the two ends of two shortest processing paths. In the actual processing process, before jumping between two shortest processing paths, the processed plate will be moved first to align the next shortest processing path with multiple punching holes 3 on the main body 1. The specific implementation method is shown in the generation method of the displacement parameters. Step S6: Generate the displacement parameters of the punch 67 and the processed plate based on multiple shortest processing paths and the processing sequence of each shortest processing path. During the processing, when switching to the next shortest processing path, in order to reduce the moving stroke of the punch 67, usually the starting point of the next shortest processing path on the processed sheet is moved towards the punch 67. However, in the actual operation process, since the punch 67 needs to move frequently, the durability of its supporting moving components is relatively high. On the one hand, for the clamping mechanism 5: the displacement amount is small and not frequent, and it only drives the processed sheet to move when switching to the next shortest processing path during the processing, which leads to low durability of the moving components in the clamping mechanism 5. On the other hand, the processed sheet itself is heavy, and the large-area contact with the upper surface of the main body 1 results in a relatively high torque requirement during movement, so the displacement accuracy is low. To ensure the accuracy, it is necessary to minimize the displacement amount as much as possible. When these two requirements conflict, it is necessary to determine the specific displacement direction of the processed sheet according to the weighted algorithm. For example, when the punch 67 completes the first shortest processing path and needs to switch to the starting point of the second shortest processing path, but at this time the starting point of the second shortest processing path does not align with the multiple punching holes 3 on the top of the main body 1, it is necessary to move the processed sheet so that the starting point of the second shortest processing path aligns with the punching holes. At this time, the processed sheet can be moved up or down. Specifically, whether to move up or down depends on the one hand, the moving amounts of the sheet moving up and down, and on the other hand, the displacement amount of the punch 67 after the movement (for example, when one of the punching holes 3 closest to the starting point of the second shortest processing path is away from the punch 67 compared to the starting point, at this time, it is necessary to comprehensively evaluate the moving direction of the sheet through the weighted algorithm).

[0028] Among them, the method for generating the displacement parameters of the processed sheet is as follows: Step S61: Based on the starting point coordinates of the next shortest processing path, find two adjacent center points in the center point coordinate system of the multiple punching holes 3 on the main body 1, and mark the adjacent center point closer to the current punch 67 position as the first target point, and the other as the second target point; Step S62: Calculate the first distance value between the starting point coordinates and the first target point and the second distance value between the starting point coordinates and the second target point, and respectively calculate the priority values of the first target point and the second target point through the weighted algorithm based on the first distance value and the second distance value, and screen out the third target point from the two adjacent center points based on the size of the priority values; Step S63: Generate the displacement parameters of the processed sheet based on the distance value between the starting point coordinates and the third target point.
