It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] Bezels are commonly used in the assembly structures of devices such as televisions and computers. They are formed by bending long strips of raw material. Before bending, assembly holes are typically machined into the raw material using CNC machine tools to provide the structural basis for subsequent assembly processes. For some more complex devices, multiple assembly holes of different sizes are required. Therefore, multiple different stamping dies are usually used to punch out these holes, resulting in a large number of dies and a long stamping time. Furthermore, when stamping the raw material, if a large number of holes are punched at once, significant stress can be generated, leading to deformation of the raw material.

[0022] To address this, embodiments of the present invention provide a sheet metal stamping method, apparatus, electronic device, and medium. By dividing the sheet metal into multiple processing zones and the punching module into multiple punching zones, multiple processing zones can be punched simultaneously through multiple punching zones. Each punching zone has a different punch head assembly, and each punching zone can punch through holes of different sizes. Thus, a single punching module can form through holes of various sizes, eliminating the need for multiple punching modules. Simultaneously, a first stamping machine pre-punches the sheet metal, reducing stress during stamping and creating dividing holes. This allows the sheet metal to be divided into two pieces, and the punching of both pieces can be completed in a single stamping cycle, thereby improving punching efficiency.

[0023] The sheet metal stamping method, apparatus, electronic equipment, and medium of the present invention will now be described in detail with reference to the accompanying drawings.

[0024] On the one hand, embodiments of the present invention propose a sheet metal stamping method, such as... Figure 1 As shown, the method includes, but is not limited to, steps S100 to S600: Step S100: Obtain the design file of the board 400. The design file contains the dimensional information and processing information of the board 400. The board 400 is provided with a partition notch. It should be noted that, since through holes of different sizes need to be formed on the sheet metal 400, the dimensional and processing information of the sheet metal 400 needs to be determined in advance. The dimensional information refers to the length, width, and thickness of the sheet metal 400, and the processing information refers to the specific locations where through holes need to be formed on the sheet metal 400, as well as which size of through hole corresponds to different locations. Based on the actual product requirements, a sheet metal 400 of the corresponding size needs to be selected. Then, the processing information of the sheet metal 400 is determined, a design file is generated, and input into the controller, enabling the controller to control the entire stamping process according to the design file. Simultaneously, in this application, the sheet metal 400 is pre-set with a dividing notch, which serves as an indicator. Subsequently, the sheet metal 400 can be divided into two plates 420, left and right, according to this dividing notch. The structure and stamping process of each plate 420 are completely identical. In this way, two plates 420 can be formed simultaneously in one stamping cycle. Each plate 420 can flow into subsequent processes for bending and other operations to form a frame. This method can further improve the stamping efficiency of the sheet metal 400.

[0025] Step S200: The sheet metal 400 is transferred to the processing track 500 by the conveying device 100. The processing track 500 passes through the first punching machine 200 and the second punching machine 300 in sequence. The second punching machine 300 is equipped with a punching module and a punching module. The punching module includes multiple punches with telescopic and adjustable diameter. An isolation member 510 is provided at the exit of the processing track 500. Specifically, such as Figure 2 As shown, the processing track 500 serves to limit the movement of the sheet metal 400. During the stamping process, the conveying device 100 moves the sheet metal 400 along the processing track 500 by a preset step each time. Each time the sheet metal 400 moves, the first stamping machine 200 and the second stamping machine 300 stamp the sheet metal 400 once, achieving continuous stamping of different positions on the sheet metal 400. The first stamping machine 200 is used to pre-stamp the sheet metal 400 to form a separating hole 430. The separating hole 430 and the separating notch are on the same straight line. Subsequently, any two adjacent separating holes 430 need to be connected to form a separating groove 410, thereby dividing the sheet metal 400 into two plates 420. The punching module is mainly used to simultaneously punch the required through holes on the two plates 420. The cutting module is used to cut off the connecting section between any two adjacent separating holes 430, connecting the adjacent separating holes 430. When the sheet 400 moves to the exit of the processing track 500, the separator 510 can divide the sheet 400 into two pieces 420 along the dividing groove 410.

[0026] Step S300: According to the design documents, the sheet metal 400 is divided into multiple processing areas, the punching module is divided into multiple punching areas, and the punch group corresponding to each punching area is determined. The processing area and the punching area correspond one-to-one. Each punch group includes multiple punches with corresponding extension length and diameter. Specifically, after obtaining the design documents, areas with identical through-hole distribution are divided into processing zones based on the distribution of through-holes. This divides the sheet metal 400 into multiple identical processing zones. During processing, the preset step size of the sheet metal 400 movement is equal to the length of the processing zone. Simultaneously, to punch holes in each processing zone at the same time, the punching module is divided into multiple punching areas, each corresponding to one processing zone. Thus, when the last punching area in the processing direction punches the first processing zone, the second-to-last punching area punches the second processing zone, and the first punching area punches the Nth processing zone, where N equals the number of punching areas. In this way, as each processing zone advances along the processing track 500, it sequentially passes through the first punching area, the second punching area, ..., the Nth punching area, being punched once by each area. After N punching operations, all the required through-holes are formed. During the punching process, a corresponding set of punches is selected for punching. Each punching zone has a different set of punches, thus punching through holes of different sizes at different locations on the 400mm sheet metal. Each set of punches includes multiple punches. Since the extension length and diameter of the punches are adjustable, the arrangement of the punches in the set, as well as the extension length and diameter of each punch, can be determined according to the required size and layout of the through holes.

[0027] Step S400: When the sheet metal 400 moves along the processing direction on the processing track 500, the first punching machine 200 pre-punches each processing area of ​​the sheet metal 400 along the extension direction of the separation notch, forming a number of spaced separation holes 430 in each processing area. Since the sheet metal 400 moves in steps equal to the length of one processing zone, the first punch 200 pre-punches the sheet metal 400 once each time it moves along the processing direction, forming several spaced-apart partition holes 430 within the corresponding processing zone. The center of each partition hole 430 is aligned with the partition notch, facilitating the subsequent connection of multiple partition holes 430 to form a partition groove 410, thereby dividing the sheet metal 400 into two equal parts 420.

[0028] Step S500: Each punch group of the punching module punches the corresponding processing area to form through holes of the corresponding size; Specifically, after passing through the first stamping machine 200, the sheet metal 400 continues to move along the processing track 500 and enters the second stamping machine 300. After passing through the second stamping machine 300, the punching module begins to punch the sheet metal 400. Multiple punching zones will operate simultaneously, with each punching zone punching different processing zones to form through holes of corresponding sizes in each processing zone.

[0029] Step S600: The connecting section between several partition holes 430 in each processing area is punched sequentially by the punching module, so that several partition holes 430 are interconnected to form a partition groove 410. After the processing area of ​​the sheet 400 passes through all the punching areas, it reaches the punching module. The punching module will punch the connecting section between several partition holes 430 in the processing area, so that several partition holes 430 are interconnected to form a partition groove 410.

[0030] Step S700: When the sheet 400 reaches the exit of the processing track, the sheet 400 is divided into two equal-sized plates 420 by the separator 510 along the dividing groove 410.

[0031] When the sheet metal 400 reaches the exit of the processing track, the separator 510 inserts into the dividing slot 410, thereby dividing the sheet metal 400 into two plates 420 of equal size. In this way, the punching of two plates 420 can be completed simultaneously in one punching cycle, thereby improving punching efficiency.

[0032] According to the sheet metal stamping method of the present invention, the sheet metal 400 is divided into multiple processing areas, and the punching module is divided into multiple punching areas. Multiple punching areas simultaneously punch multiple processing areas, and each punching area has a different punch head group. Each punching area can punch through holes of different sizes, thus forming multiple through holes of different sizes using a single punching module, eliminating the need for multiple punching modules. Simultaneously, the sheet metal 400 is pre-punched using a first punching machine 200, which reduces stress during stamping and forms dividing holes 430. This allows the sheet metal 400 to be divided into two equal parts 420, and the punching of both parts 420 can be completed simultaneously in one stamping cycle, thereby improving punching efficiency.

[0033] Furthermore, in some embodiments of this application, the surface of the processing track 500 of the second stamping machine 300 is provided with multiple adjustable limiting holes. Correspondingly, each punch is formed by multiple telescopic sleeves. The diameter of the punch can be adjusted by controlling the extension and retraction state of each telescopic sleeve, and each punch corresponds to one limiting hole. In this example, step S300 above: determining the punch group corresponding to each punching area includes the following five sub-steps: Step S310: Based on the processing information, classify all through holes in the processing area to obtain several through hole groups, and sort the processing order of the through hole groups; each through hole group corresponds to a punching area, and each through hole group includes multiple through holes; Step S320: According to the through hole arrangement and processing sequence of the through hole group, set the punch group for each punching area in sequence; Step S330: Extend the punches belonging to the punch group in the punching area downwards out of the bottom surface of the punching module, while the punches not belonging to the punch group are in a retracted state and located inside the punching module. Step S340: Adjust the diameter of the punch in each punching zone according to the size of the through hole in each through hole group; Step S350: Based on the size of the through holes in each through hole group, determine the opening of each limiting hole of the machining track 500 so that the punch matches the corresponding limiting hole.

[0034] It should be noted that since through holes come in various types and sizes, the processing sequence for each type of through hole needs to be determined to optimize the stamping process and minimize stress on the processing area during stamping. Therefore, in this example, all through holes in the processing area are classified into multiple through hole groups, each group containing multiple through holes, and each group corresponds to a punching area. Then, based on the arrangement of the through holes within each group and the processing sequence of the through hole groups, the punch group for each punching area is determined. For example, the first punching area is responsible for punching the through holes in the first group, the second punching area is responsible for punching the through holes in the second group, and so on. Therefore, the size and arrangement of the punches in the first punching area's punch group must correspond to the size and arrangement of the through holes in the first group, and the punch groups in other punching areas are also adapted to their corresponding through hole groups. To ensure the punch assembly in the punching area can punch out the required through holes, the diameter of the punches within the punch assembly is adjustable. Each punch is formed by multiple telescopic sleeves connected together. The diameter of the punch can be adjusted by controlling the extension and retraction of each telescopic sleeve. Simultaneously, the opening of each limiting hole needs to be adjusted to match the size of the limiting hole with the corresponding punch. Furthermore, the extension state of each punch in the punch assembly needs to be controlled according to the arrangement of the through holes. Punches in positions requiring through holes should remain extended, while punches in positions not requiring through holes should remain retracted. Thus, when the stamping die descends, punches in the extended state will punch the sheet metal 400, while punches in the retracted state will not punch, thereby forming the required through hole assembly.

[0035] Furthermore, in some embodiments of this application, step S310 above—classifying all through holes in the processing area according to processing information to obtain several through hole groups, and sorting the processing order of the through hole groups—includes the following three sub-steps: Step S311: Divide multiple through holes of the same size into the same through hole group to obtain multiple through hole groups of different sizes; Step S312: Obtain the through hole group corresponding to the through hole located at the center of all through holes, and take it as the central through hole group; Step S313: Arrange the processing sequence of the central through hole group first, and sort the processing sequence of the remaining through hole groups according to the size or spacing of the through holes in the through hole group.

[0036] Specifically, in this example, through holes are classified according to their size. Through holes of the same size are grouped into the same group, thus obtaining multiple groups of through holes with different sizes. Each punch within a stamping group maintains the same size. Then, the group of through holes located at the center of all through holes is designated as the central through hole group and is stamped first. Stamping the central through hole group first helps optimize stress distribution, making the stress distribution in that processing area more uniform and reducing the risk of deformation during subsequent punching. Then, the remaining through hole groups are sorted according to their size or spacing. The sorting method can be achieved through the following two steps: For each remaining through-hole group, the processing sequence of the through-hole group is arranged in descending order of through-hole size; or, the processing sequence of the through-hole group is arranged in descending order of through-hole spacing. Each group of through holes after arrangement is divided into a first through hole group and a second through hole group, and the processing order of the second through hole group is arranged after that of the first through hole group; wherein, the multiple through holes of the first through hole group and the multiple through holes of the second through hole group are staggered, and the first through hole group and the second through hole group correspond to different punching areas.

[0037] Specifically, when arranging the processing sequence of the through-hole group according to size from largest to smallest, larger holes can be punched first, followed by smaller holes. Similarly, when arranging the processing sequence according to the spacing between through holes from largest to smallest, sparser holes can be punched first, followed by denser holes, thereby further optimizing stress distribution and reducing the risk of deformation during punching. Furthermore, dividing each through-hole group into a first through-hole group and a second through-hole group, with the through holes in the first and second through-hole groups staggered, reduces the number of holes punched in a single pass and increases the spacing between adjacent through holes during a single punch, further reducing stress.

[0038] Furthermore, such as Figure 2As shown, in some embodiments of this application, the first stamping machine 200 has a pre-punching module 600; the above-mentioned step S400: the first stamping machine 200 sequentially pre-punches each processing area of ​​the sheet metal 400 along the extension direction of the separating notch, forming a plurality of spaced separating holes 430 in each processing area, including the following three sub-steps: Step S410: Determine the location of the dividing gap according to the design documents; Step S420: Adjust the pre-punching position of the pre-punching module 600 according to the position of the dividing notch; Step S430: The pre-punching module 600 pre-punches each processing area of ​​the sheet 400 in turn, forming several spaced-apart partition holes 430 in each processing area, so that the center of the partition hole 430 and the partition notch are on the same straight line.

[0039] Specifically, since the center of the dividing hole needs to be aligned with the dividing notch, the position of the dividing notch needs to be determined first, and then the pre-punching position of the pre-punching module 600 is adjusted so that when the pre-punching module 600 pre-punches the plate 400, the center of the dividing hole 430 formed is aligned with the dividing notch, which facilitates the subsequent stroke of the dividing groove 410 to divide the plate 400 into two plates 420.

[0040] Furthermore, such as Figure 2 As shown, in some embodiments of this application, the conveying device 100 includes a turntable 110, a drive mechanism 120 and a stepping transmission mechanism 130. The turntable 110 is provided with a receiving groove 111 for winding the sheet 400. The stepping transmission mechanism 130 is provided with a clamping member 140 and a rotating rod 150. The clamping member 140 is connected to the rotating rod 150 in a transmission connection. The rotating rod 150 is provided with a sensing element. The sensing element is electrically connected to the drive mechanism 120. The first stamping machine 200 is provided with a lower pressing bar 610 on the side near the stepping transmission mechanism 130. Step S200 above: The plate 400 is transferred to the processing track 500 by the conveying device 100, which includes the following four sub-steps: Step S210: Drive the turntable 110 to rotate via the drive mechanism 120; Step S220: The plate 400 is fed by the stepping transmission mechanism 130 according to the preset step, and the plate 400 is pressed by the clamping member 140; Step S230: When the pressure bar 610 presses down the rotating rod 150, the rotating rod 150 drives the clamping member 140 to rise, releasing the plate 400; Step S240: A sensing signal is sent to the drive mechanism 120 through the sensing element, so that the drive mechanism 120 drives the turntable 110 to rotate at a preset angle. At the same time, when the rotating rod 150 is reset, it drives the clamping member 140 to reset and clamp the plate 400.

[0041] Specifically, the drive mechanism 120 first drives the turntable 110 to rotate, causing the sheet metal 400 in the receiving groove 111 to move towards the stepping transmission mechanism 130. The stepping transmission mechanism 130 controls the transmission tension of the sheet metal 400 and the transmission step of the sheet metal 400, so that the sheet metal 400 moves along the processing track 500 according to the preset step. The stepping transmission mechanism 130 is provided with a clamping member 140 for pressing the sheet metal 400, so that the sheet metal 400 maintains the required tension for forward movement. It should be noted that when the first stamping machine 200 and the second stamping machine 300 stamp the sheet metal 400, the lower pressure bar 610 will press down the rotating rod 150, causing the clamping member 140 to rise and release the sheet metal 400. This avoids generating additional resistance during the stamping process, which could cause the material to be pulled during the stamping process, resulting in mold damage or material deformation, and thus leading to a decrease in stamping accuracy or material deformation. This ensures that the stamping mold can freely complete the stamping action.

[0042] like Figure 3 As shown, in some embodiments of this application, a cutting device 310 is further provided above the exit of the processing track 500, and a ranging element is provided at the exit of the processing track 500; the sheet metal stamping method further includes the following three steps: Based on the processing information, determine the first length of each 420 sheet; The second length of the plate 400 at the exit of the processed track 500 is obtained by using a ranging element; When the first length is equal to the second length, the cutting device 310 cuts the plate 400 downwards, so that the plate 400 is divided into two equal parts 420.

[0043] It should be noted that in practical applications, the production of different products requires frames of different sizes, which in turn requires plates 420 of different lengths. Therefore, when the stamping length of the sheet 400 reaches the required length of the plate 420, the sheet 400 can be cut by the cutting device 310 to form the plate 420 of the required length. The remaining part of the sheet 400 is then used for stamping to form subsequent plates 420. It should be noted that the cutting device 310 can be set on a separate upgrading device, or the cutter of the cutting device 310 can be set to be retractable and set on the punching module, rising and falling together with the punching module. Under normal conditions, the cutter remains in a retracted state, and only extends when the sheet 400 needs to be cut.

[0044] According to the sheet metal stamping method of the present invention, the sheet metal 400 is divided into multiple processing areas, and the punching module is divided into multiple punching areas. Multiple punching areas simultaneously punch multiple processing areas, and each punching area has a different punch head group. Each punching area can punch through holes of different sizes, thus forming multiple through holes of different sizes using a single punching module, eliminating the need for multiple punching modules. Simultaneously, the sheet metal 400 is pre-punched using a first punching machine 200, which reduces stress during stamping and forms dividing holes 430. This allows the sheet metal 400 to be divided into two equal parts 420, and the punching of both parts 420 can be completed simultaneously in one stamping cycle, thereby improving punching efficiency.
