Description

Technical Field

[0001] The present application relates to the technical field of plate processing, and in particular to a plate processing system. Background Art

[0002] In order to have a better appearance effect, many existing products will be folded. For example, in the sub-screen of the smart blackboard, the four sides of the sub-screen panel will be folded, and curved and extended curved edges may also be required to be made between the two adjacent folded edges to further enhance the appearance effect. However, in the prior art, the plates are mainly formed by integral stamping molds, and all sides of the plates are stamped out simultaneously.

[0050] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0051] An embodiment of the present application provides a plate processing system to solve the problem of low efficiency in the folding processing of existing plates, which will be described below in conjunction with the accompanying drawings.

[0052] In the embodiments of the present application, Figure 1 As shown, Figure 1 It is a top view of a panel processing system 100, which includes a conveyor line 10, a notch processing device 20, a first folding device 30 and a second folding device 40, wherein the conveyor line 10 is used to convey the panel 50 to be processed. Specifically, the structure type of the conveyor line 10 is not limited, for example, it can be a belt conveyor line, a roller conveyor line, a chain conveyor line, a mesh belt conveyor line, etc., or the conveyor line 10 can be a combination of the various conveyor line types listed above. Therefore, the specific conveyor line structure can be designed with reference to the existing technology, as long as it can stably convey the panel 50 to be processed in a preset direction.

[0053] like Figure 2 As shown, Figure 2The schematic diagram of the plate structure with the notch 51 and the cut 52 processed is shown in the figure. In the present embodiment, before the plate 50 to be processed is placed on the conveyor line 10, its size is sufficient to process multiple formed plates 55 (i.e., plates that have completed the folding process). For example, taking the plate 50 as a steel plate, the plate 50 is generally rolled before processing, which is convenient for storage and transportation. When processing is required, the plate 50 will be straightened and then placed on the conveyor line 10, and the conveyor line 10 will then transport the plate 50 to various processing devices. In the present embodiment of the application, the width of the plate 50 before processing is slightly larger than the width of the formed plate 55, and the length is larger than the sum of the lengths of multiple formed plates 55, so that multiple formed plates 55 can be processed by cutting.

[0054] In this embodiment, the notch processing device 20 is used to process the notch 51 on both sides of the width direction of the plate 50. Specifically, after the plate 50 is placed on the conveyor line 10, the conveyor line 10 will first convey the plate 50 to the notch processing device 20, and the notch processing device 20 is used to process the notch 51 on both sides of the width direction of the plate 50. Figure 2 As shown, two notches 51 are spaced opposite to each other along the width direction of the plate 50, and each notch 51 is located at the boundary between two formed plates 55 to be separated. In practical application, the conveyor line 10 can be controlled to start and stop according to the length of the formed plate 55. For example, when the length of the plate 50 exceeding the notch processing device 20 is exactly the length of one formed plate 55, it means that the notch processing device 20 is exactly between the two formed plates 55 to be separated. At this time, the conveyor line 10 can be controlled to stop, and then the notch processing device 20 can be controlled to process the notch 51 on the plate 50.

[0055] It should be noted that the notch processing device 20 can have various structural types, for example, the notch processing device 20 can be a laser cutting device, a water cutting device, a wire cutting device, a stamping die, etc., as long as it can process the notch 51 on the plate 50. In addition, in order to process the notch 51 on both sides of the width direction of the plate 50, the notch processing device 20 can be provided with two processing components, such as one notch processing device 20 is equipped with two laser heads or two punches, etc., or the notch processing device 20 can be provided with two sets, and the two sets of notch processing devices 20 are respectively arranged on both sides of the width direction of the conveyor line 10.

[0056] Please refer to Figure 1The first folding device 30 and the second folding device 40 are both located on the downstream side of the notch processing device 20 along the conveying direction of the conveyor line 10. After the notch processing device 20 processes the notch 51, the conveyor line 10 continues to convey the plate 50 to the first folding device 30 or the second folding device 40. The order of the first folding device 30 and the second folding device 40 can be flexibly set according to actual conditions. For example, if the plate 50 is deformed after the first folding device 30 is processed, the plate 50 will not be able to pass through the second folding device 40. , the second folding device 40 can be arranged on the upstream side of the first folding device 30; similarly, if the deformation of the plate 50 after the plate 50 is processed by the second folding device 40 will cause the plate 50 to be unable to pass through the first folding device 30, the first folding device 30 can be arranged on the upstream side of the second folding device 40; of course, if the plate 50 is processed by one of the first folding device 30 and the second folding device 54 without affecting its passing through the other, the order of the first folding device 30 and the second folding device 40 can be set arbitrarily.

[0057] The first folding device 30 is used to process the cutout 52 and the first folding edge 53 on the plate 50. Figure 2 As shown, the two ends of the cut-off opening 52 are respectively connected to the two notches 51, so that the plate 50 can be cut to divide the plate 50 into a plurality of formed plates 55, and the first folding edge 53 is located on the side of the plate 50 close to the cut-off opening 52. There are many ways for the first folding edge device 30 to process the cut-off opening 52, such as the first folding edge device 30 can process the cut-off opening 52 by laser cutting, water jet cutting, wire cutting, stamping die stamping, etc., and different processing methods will result in different widths of the cut-off opening 52, so it is necessary to leave enough plate margin between the two formed plates 55 to be divided according to the actual processing method.

[0058] In addition, you can refer to Fig.13 or Fig.14 There are also many ways for the first folding device 30 to process the first folding edge 53. For example, the first folding device 30 can fold the side of the plate 50 through a stamping die, a folding roller, a flipping robot arm, etc., and then process the first folding edge 53. It should be noted here that, if Figure 2As shown, after the first folding device 30 processes the cutout 52, the plate 50 is divided into two parts, one part is located at the upstream side of the cutout 52, and the other part is located at the downstream side of the cutout 52. The first folding device 30 of the present application is used to process the first folding edge 53 on the side of the plate 50 close to the cutout 52. Therefore, the first folding device 30 processes the first folding edge 53 on the plate 50 located at the upstream side of the cutout 52 and the plate 50 located at the downstream side of the cutout 52. In other words, the two opposite first folding edges 53 on a formed plate 55 are processed in two adjacent processes.

[0059] like Fig.15 As shown, the second folding device 40 is used to process the second folding edge 54 on both sides in the width direction of the plate 50. Similarly, there may be multiple ways for the second folding device 40 to process the second folding edge 54. For example, the second folding device 40 may fold the two side edges in the width direction of the plate 50 through a stamping die, a folding roller, a flipping robot arm, etc.

[0060] Please combine Figure 2 , Fig.10 , Fig.13 and Fig.14 Because the notch 51 is processed on the plate 50 in advance, and the notch 51 weakens or disconnects the connection between the first fold 53 and the second fold 54, when the first fold 53 and the second fold 54 are processed separately, the notch 51 makes it possible for the processing of the first fold 53 and the processing of the second fold 54 to not cause much interference or even no interference, so that the folds on each plate 50 can be processed separately. Fig.15 As shown, by machining the notch 51 in advance, when the top corner of the forming plate 55 needs to be machined with a rounded edge or a chamfered edge, the rounded edge or the chamfered edge can be machined more conveniently.

[0061] In summary, when the plate processing system 100 provided in the present application needs to be flipped, the plate 50 to be processed can be placed on the conveying line 10 , which can convey the plate 50 to the notch processing device 20 ; the notch processing device 20 can process the notch 51 on both sides in the width direction of the plate 50 . Then the conveying line 10 transports the plate 50 to the first folding device 30 and the second folding device 40 respectively. The first folding device 30 can process the cutting opening 52 between the two notches 51 of the plate 50, and the first folding edge 53 is processed on the side of the plate 50 close to the cutting opening 52, and the second folding device 40 can process the second folding edge 54 on both sides of the width direction of the plate 50, thereby completing the folding edge processing of the plate 50. Therefore, the plate processing system 100 provided in the present application continuously conveys the plate 50 to the notch processing device 20, the first folding device 30 and the second folding device 40 through the conveyor line 10, and can automatically perform folding processing on each plate 50. Compared with the processing method of placing and removing multiple plates 50 one by one on the stamping die, the plate processing system 100 provided in the present application greatly improves the folding processing efficiency of the plate 50.

[0062] Optionally, in one embodiment, as Figure 3 As shown, the notch processing device 20 includes a first punch 21 and a first die 22 , the first die 22 is provided with a first groove 23 , and the first punch 21 is used to punch a part of the plate body of the plate 50 into the first groove 23 to punch the notch 51 on the plate 50 . That is, the notch processing device 20 processes the notch 51 on the plate 50 by mold stamping. It can be understood that this arrangement makes the structure of the notch processing device 20 simple and easy to obtain and easy to control, thereby avoiding the plate processing system 100 being too complicated.

[0063] The shapes of the first punch 21 and the first groove 23 need to be designed according to the shape of the notch 51. For example, in this embodiment, Fig.13 As shown, at least one vertex on the plate 50 needs to be processed into a rounded edge, so before the edge is folded, as shown in FIG. Figure 8 As shown, the notch 51 on the plate 50 at least includes a first inner wall surface 511, a bent inner wall surface 514 and a second inner wall surface 512 connected in sequence; wherein the first inner wall surface 511 extends along the width direction of the plate 50, as shown in FIG. Fig.13 As shown, when the plate 50 completes the processing of the second folded edge 54, the first inner wall surface 511 forms a part of the side wall of the second folded edge 54. The second inner wall surface 512 extends along the length direction of the plate 50, as shown in FIG. Fig.13As shown, when the plate 50 completes the processing of the first folded edge 53, the second inner wall surface 512 forms a part of the side wall of the first folded edge 53. The bent inner wall surface 514 is connected between the first inner wall surface 511 and the second inner wall surface 512, and the bent inner wall surface 514 is bent and extended, as shown in FIG. Fig.13 As shown, when the plate 50 completes the processing of the first folded edge 53 , the second inner wall surface 512 is located on the curved extension section 532 (ie, the rounded folded edge) of the first folded edge 53 , and the second inner wall surface 512 forms a partial top wall of the first folded edge 53 .

[0064] In this regard, in this embodiment, if Figure 4 As shown, the first punch 21 includes a first side wall 211, a bent side wall 213 and a second side wall 212 connected in sequence; wherein the first side wall 211 extends along the width direction of the conveyor line 10, please refer to Figure 8 After the first punch 21 punches out the notch 51 on the plate 50, the notch 51 forms a first inner wall surface 511 corresponding to the first side wall 211, that is, the first side wall 211 enables the first punch 21 to punch out a part of the side wall of the second folded edge 54 on the plate 50. The second side wall 212 extends along the length direction of the conveyor line 10, please combine Figure 8 After the first punch 21 punches out the notch 51 on the plate 50, the notch 51 forms a second inner wall surface 512 corresponding to the second side wall 212, that is, the second side wall 212 enables the first punch 21 to punch out a partial side wall of the first folded edge 53 on the plate 50. The bent side wall 213 is bent and extended toward the inside of the first punch 21. Figure 8 After the first punch 21 punches out the notch 51 on the plate 50, the notch 51 forms a bent inner wall surface 514 corresponding to the bent side wall 213, that is, the bent side wall 213 enables the first punch 21 to punch out a portion of the top wall of the first folded edge 53 on the plate 50. It can be understood that after the first punch 21 punches out the notch 51 in this embodiment, on the one hand, the connection between the first folded edge 53 and the second folded edge 54 can be weakened, and on the other hand, the folding height of the rounded folded edge can be reduced, so that when the first folded edge 53 and the second folded edge 54 are processed separately, the processing of the first folded edge 53 and the processing of the second folded edge 54 will not cause significant interference, and it is also convenient to process the rounded folded edge.

[0065] Correspondingly, such as Figure 6As shown, in order to cooperate with the first punch 21, the first groove 23 includes a first inner wall 231, a bent inner wall 233 and a second inner wall 232 connected in sequence, the first inner wall 231 is correspondingly parallel to the first side wall 211, the bent inner wall 233 is correspondingly parallel to the bent side wall 213, and the second inner wall 232 is correspondingly parallel to the second side wall 212. In the process of the first punch 21 extending into and out of the first groove 23, the first side wall 211 slides parallel to the first inner wall 231, the second side wall 212 slides parallel to the first inner wall 231, and the bent side wall 213 slides parallel to the bent inner wall 233.

[0066] Further, such as Figure 4 As shown, the bent side wall 213 includes an arc segment 2131 and an inclined segment 2132; one end of the arc segment 2131 is connected to the second side wall 212, and the other end is connected to the inclined segment 2132, and the other end of the inclined segment 2132 is connected to the first side wall 211; the arc segment 2131 has an arc center side 2133 and an arc outer side 2134 opposite to each other, and the inclined segment 2132 is biased toward the arc center side 2133. Figure 8 As shown, when the notch 51 is punched out on the plate 50 by the first punch 21 in this embodiment, the bent inner side wall of the notch 51 also includes an arc-shaped inner wall section 5141 and an inclined inner wall section 5142 which are connected to each other. Because the inclined section 2132 on the first punch 21 is biased toward the arc center side of the arc-shaped inner wall section 5141, the inclined inner wall section 5142 of the notch 51 will also be correspondingly biased toward the arc center side 2133 of its arc-shaped inner wall section 5141. In this way, the width of the connecting plate body between the first folded edge 53 and the second folded edge 54 can be reduced, thereby further weakening the connection between the first folded edge 53 and the second folded edge 54, so that the second folded edge 54 after processing will not cause greater interference to the processing of the first folded edge 53, thereby better processing the curved extension section 532 of the first folded edge 53, that is, better processing the rounded folded edge of the plate 50.

[0067] It should be noted that the curvature radius of the arc segment 2131 can be set to be the same as the curvature radius of the folding mark of the rounded folded edge, and then after the first punch 21 punches out the notch 51, the arc inner wall segment 5141 on the notch 51 extends parallel to the folding mark 56 of the rounded folded edge; the inclination angle of the inclined section 2132 is not limited, and can be flexibly set according to specific circumstances in actual application, as long as the inclined section 2132 is inclined as a whole toward the arc center side 2133 of the arc segment 2131 when extending from the arc segment 2131 to the first side wall 211, and it is ensured that after folding, the curved extension section 532 of the first folded edge 53 has a certain height.

[0068] Further, such as Figure 5As shown, the inclined section 2132 includes a first inclined section 2135, a connecting section 2136 and a second inclined section 2137 connected in sequence. One end of the first inclined section 2135 is connected to the second side wall 212, and the other end is connected to one end of the connecting section 2136; the other end of the second inclined section 2137 is connected to the first side wall 211, and the other end is connected to the other end of the connecting section 2136; the connecting section 2136 extends along the width direction of the conveyor line 10, and the connecting section 2136 is used to enable the first punch 21 to punch out a transition step surface 513 on the plate 50, as shown in FIG. Fig. 9 As shown, after the first punch 21 punches out the notch 51 on the plate 50, the inclined inner wall section 5142 of the notch 51 includes a first inclined inner wall section 5143, a connecting inner wall section 5144, and a second inclined inner wall section 5145 connected in sequence, wherein the connecting inner wall section 5144 forms a transition step surface 513, and the transition step surface 513 has a transition end 5131 closer to the other notch 51, that is, the transition end 5131 is connected to the first inclined inner wall section 5143, and in the extension direction of the second folding edge 54, the transition end 5131 is flush with the folding position of the second folding edge 54, that is, when the folding mark 56 of the second folding edge 54 is extended, the folding mark 56 of the second folding edge 54 will pass through the transition end 5131 of the transition step surface 513. Therefore, Fig.10 As shown, when the second folding device 40 processes the second folding edge 54, because the transition end 5131 of the transition step surface 513 is flush with the folding position of the second folding edge 54, the second inclined inner wall section 5145 of the notch 51 will also follow the second folding edge 54 to fold upward, and because the transition step surface 513 is provided, the second folding edge 54 will not cause the first inclined inner wall section 5143 and the arc-shaped inner wall section 5141 to fold or deform when folding, thereby avoiding the first folding edge 53 and the second folding edge 54 from interfering with each other when folding, so as to better process the first folding edge 53 and the second folding edge 54 respectively, especially to better process the curved extension section 532 (i.e., the rounded folding edge) of the first folding edge 53.

[0069] Similarly, if Figure 6 As shown, in order to cooperate with the first punch 21, the bent inner wall 233 of the first groove 23 includes an arc segment 2331 and an inclined segment 2332 connected in sequence, the arc segment 2331 is parallel to the arc segment 2131, and the inclined segment 2332 is parallel to the inclined segment 2132. Figure 7 As shown, the inclined surface section 2332 also includes a first inclined surface section 2333, a connecting section 2334 and a second inclined surface section 2335 connected in sequence, the first inclined surface section 2333 corresponds to and is parallel to the first inclined section 2135, the connecting section 2334 corresponds to and is parallel to the connecting section 2136, and the second inclined surface section 2335 corresponds to and is parallel to the second inclined section 2137.

[0070] Optionally, in one embodiment, as Fig.14 As shown, at least one vertex of the plate 50 needs to be processed into a right-angle fold. Therefore, before folding, as shown in FIG. Figure 8 As shown, the notch 51 on the plate 50 needs to include at least a third inner wall surface 515, a fourth inner wall surface 516 and a connecting inner wall surface 517 connected in sequence; wherein the third inner wall surface 515 extends along the width direction of the plate 50, as shown in FIG. Fig.14 As shown in FIG. 1 , when the plate 50 completes the processing of the second folded edge 54, the third inner wall surface 515 forms the side wall of the second folded edge 54. The fourth inner wall surface 516 extends along the length direction of the plate 50, and the fourth inner wall surface 516 forms the side wall of the first folded edge 53. The connecting inner wall surface 517 is connected between the second inner wall surface 512 and the fourth inner wall surface 516, as shown in FIG. Figure 2 As shown, when the first folding device 30 processes the cutting opening 52 on the plate 50, the connecting inner wall surface 517 is cut away together.

[0071] In this regard, Figure 4 As shown, the first punch 21 further includes a third side wall 214, a fourth side wall 215 and a connecting side wall 216 connected in sequence; the third side wall 214 extends along the width direction of the conveyor line 10, as shown in FIG. Figure 8 As shown, after the first punch 21 punches out the notch 51 on the plate 50, the notch 51 forms a third inner wall surface 515 corresponding to the third side wall 214, that is, the third side wall 214 enables the first punch 21 to punch out another side wall of the second folded edge 54 on the plate 50; the fourth side wall 215 extends along the length direction of the conveyor line 10, as shown in FIG. Figure 8 As shown, after the first punch 21 punches out the notch 51 on the plate 50, the notch 51 forms a fourth inner wall surface 516 corresponding to the fourth side wall 215, that is, the fourth side wall 215 enables the first punch 21 to punch out another side wall of the first folded edge 53 on the plate 50; one end of the connecting side wall 216 is connected to the fourth side wall 215, and the other end is connected to the second side wall 212, as shown in FIG. Figure 8 As shown, after the first punch 21 punches out the notch 51 on the plate 50, the notch 51 forms an inner wall surface 517 connected to the corresponding connecting side wall 216, thereby connecting the second inner wall surface 512 and the fourth inner wall surface 516. Therefore, after the first punch 21 in this embodiment punches out the notch 51, a third inner wall surface 515 and a fourth inner wall surface 516 whose extending directions are perpendicular to each other can be formed, and then after the first folding edge 53 and the second folding edge 54 are folded, the top angle of the plate 50 can be processed into a right-angle folding edge.

[0072] Correspondingly, such as Figure 6As shown, in order to cooperate with the first punch 21, the first groove 23 further includes a third inner wall 234, a fourth inner wall 235 and a connecting inner wall 236 which are connected in sequence, the third inner wall 234 is correspondingly parallel to the third side wall 214, the fourth inner wall 235 is correspondingly parallel to the fourth side wall 215, and the connecting inner wall 236 is correspondingly parallel to the connecting side wall 216. In the process of the first punch 21 extending into and out of the first groove 23, the third side wall 214 slides parallel to the third inner wall 234, the fourth side wall 215 slides parallel to the fourth inner wall 235, and the bent side wall 213 slides parallel to the bent inner wall 233.

[0073] Optionally, in one embodiment, as Figure 4 As shown, the first punch 21 also includes a first positioning side wall 217 and a second positioning side wall 218; the first positioning side wall 217 is connected to the first side wall 211, and the first positioning side wall 217 extends along the length direction of the conveyor line 10; the second positioning side wall 218 is connected to the third side wall 214, and the second positioning side wall 218 extends along the length direction of the conveyor line 10. It can be understood that by providing the first positioning side wall 217 and the second positioning side wall 218 on the first punch 21, the first punch 21 and the first die 22 can be accurately aligned during assembly, thereby improving assembly efficiency, and during use, it is also possible to determine whether the first punch 21 is deflected relative to the first die 22 by observing the positions of the first positioning side wall 217 and the second positioning side wall 218, so as to facilitate timely correction.

[0074] Optionally, in one embodiment, as Figure 3 or Figure 6 As shown, the first groove 23 also passes through the side wall and the bottom wall of the first die 22, which can simplify the structure of the first die 22 and reduce the weight of the first groove 23, making the notch processing device 20 simpler and lighter.

[0075] Optionally, in one embodiment, please combine 11 and Fig.12 The first folding device 30 includes a second punch 31 and a second die 32. The second die 32 is provided with a second groove 321. The second punch 31 is used to punch a part of the plate 50 into the second groove 321 to punch out a cutout 52 on the plate 50. In other words, the first folding device 30 processing device processes the notch 51 on the plate 50 by die stamping. It can be understood that such a setting makes the structure of the first folding device 30 simple and easy to obtain, convenient to control, and has low requirements on the use environment, thereby avoiding the plate processing system 100 from being too complicated.

[0076] Optionally, in one embodiment, please combine 11 and Fig.12The first folding device 30 also includes a folding punch 33 and a folding die 34. The folding die 34 is provided with a folding groove 35. The folding punch 33 is used to press part of the plate body of the plate 50 into the folding groove 35 to process the first folding edge 53 on the plate body. In other words, the notch processing device 20 also processes the first folding edge 53 on the plate 50 by die stamping. It can be understood that such a setting makes the structure of the first folding edge 53 simple and easy to obtain, and because the cut-off 52 and the first folding edge 53 are both stamped out by die stamping, the first folding device 30 can be further made more convenient to control, and the requirements for the use environment are not high, thereby avoiding the plate processing system 100 from being too complicated.

[0077] Furthermore, since there are two top corners on the plate 50 that need to be processed into rounded edges, in this embodiment, Fig.11 As shown, the hemming punch 33 includes a third punch 36, and the third punch 36 includes a fifth side wall 361, an arcuate side wall 362 and a sixth side wall 363 connected in sequence; the fifth side wall 361 extends along the length direction of the conveyor line 10; the sixth side wall 363 extends along the width direction of the conveyor line 10, and the sixth side wall 363 is used to enable the third punch 36 to punch out a portion of the first hem 53 on the plate 50, so that the first hem 53 has a straight extension section 531; the arcuate side wall 362 is bent and extended between the fifth side wall 361 and the sixth side wall 363, and the arcuate side wall 362 is used to enable the third punch 36 to punch out a portion of the first hem 53, so that the first hem 53 has a curved extension section 532; correspondingly, as shown Fig.12 As shown, in order to cooperate with the third punch 36, the folding die 34 includes a third die 37, and the third die 37 is provided with a third groove 371. The third groove 371 includes a fifth inner wall 372, an arcuate inner wall 373 and a sixth inner wall 374 connected in sequence. The fifth inner wall 372 is parallel to the fifth side wall 361, the arcuate inner wall 373 is parallel to the arcuate side wall 362, and the sixth inner wall 374 is parallel to the sixth side wall 363.

[0078] In this embodiment, because the fifth side wall 361 extends along the length direction of the conveyor line 10, when the third punch 36 moves up and down, the fifth side wall 361 moves up and down parallel to the second folded edge 54, and thus does not interfere with the second folded edge 54. Because the sixth inner wall 374 is correspondingly parallel to the sixth side wall 363, when the third punch 36 presses the plate 50 downward, the side edge of the plate 50 near the cut-off opening 52 will be bent and deformed under the clamping of the sixth side wall 363 and the sixth inner wall 374, and then folded into a straight extension section 531 of the first folded edge 53 (please refer to Fig.13Because the arc-shaped inner wall 373 is parallel to the arc-shaped side wall 362, when the third punch 36 presses the plate 50 downward, the side edge of the plate 50 near the cut-off opening 52 will bend and deform under the clamping of the arc-shaped side wall 362 and the arc-shaped inner wall 373, and then fold into a curved extension section 532 of the first folded edge 53 (see Fig.13 ). Therefore, after the plate 50 is processed, a rounded edge can be formed at the top corner to improve the appearance.

[0079] Furthermore, since there are two vertex angles on the plate 50 that need to be processed into right-angled edges, in this embodiment, Fig.11 As shown, the hemming punch 33 also includes a fourth punch 38, and the fourth punch 38 includes a seventh side wall 381 and an eighth side wall 382 connected to each other; the seventh side wall 381 extends along the length direction of the conveyor line 10; the eighth side wall 382 extends along the width direction of the conveyor line 10, and the eighth side wall 382 is used to enable the fourth punch 38 to punch out another first hem 53 on the plate 50. Correspondingly, as Fig.12 As shown, the folding die 34 also includes a fourth die 39, which is provided with a fourth groove 391. The fourth groove 391 includes a seventh inner wall 392 and an eighth inner wall 393 which are connected to each other. The seventh inner wall 392 is parallel to the seventh side wall 381, and the eighth inner wall 393 is parallel to the eighth side wall 382.

[0080] In this embodiment, because the seventh side wall 381 extends along the length direction of the conveyor line 10, when the fourth punch 38 moves up and down, the seventh side wall 381 moves up and down parallel to the second folded edge 54, and thus does not interfere with the second folded edge 54. Because the eighth inner wall 393 is correspondingly parallel to the sixth side wall 363, when the fourth punch 38 presses the plate 50 downward, the side edge of the plate 50 near the cut-off opening 52 will bend and deform under the clamping of the eighth side wall 382 and the eighth inner wall 393, and then fold into the first folded edge 53 extending in a straight line (please refer to Fig.14 ), the first folded edge 53 extends perpendicularly to the second folded edge 54. Therefore, after the plate 50 is processed, a right-angle folded edge can be formed at its top corner.

[0081] Optionally, in one embodiment, as Fig.11As shown, the first folding device 30 also includes a lifting base 310, and the second punch 31, the third punch 36 and the fourth punch 38 are all connected to the lifting base 310, so that the second punch 31, the third punch 36 and the fourth punch 38 can be controlled to move up and down synchronously. In order to ensure that the processing of the first folding edge 53 is carried out after the processing of the cutting opening 52 is completed, in this embodiment, the second punch 31 protrudes from the third punch 36 and the fourth punch 38 to the side where the conveyor line 10 is located, so that the second punch 31 will contact the plate 50 before the third punch 36 and the fourth punch 38, and then after the second punch 31 punches out the cutting opening 52, the third punch 36 and the fourth punch 38 start to process the first folding edge 53, so as to avoid the situation that the two first folding edges 53 are pulled when the two first folding edges 53 are punched before the plate 50 is cut, thereby affecting the folding quality.

[0082] Optional, such as Fig.12 As shown, in one embodiment, the second die 32, the third die 37 and the fourth die 39 are integrally formed, which can simplify the structure of the first folding device 30.

[0083] Optionally, in one embodiment, as Fig.15 and Fig.16 As shown, the second folding device 40 includes a first folding roller 41 and a second folding roller 42, which are arranged at intervals along the width direction of the conveyor line 10, and the end surface of the first folding roller 41 and the end surface of the second folding roller 42 are spaced to form a folding gap 43, and the folding gap 43 is used for a part of the side edge of the plate 50 to be inserted, so as to fold out a second folding edge 54 on the plate 50. Specifically, in this embodiment, the first folding roller 41 is located above the conveyor line 10, and the second folding roller 42 is located on one side of the conveyor line 10. When the conveyor line 10 conveys the plate 50 to the first folding roller 41 and the second folding roller 42, the side edge of the plate 50 will be inserted into the folding gap 43 between the first folding roller 41 and the second folding roller 42, and then the side edge of the plate 50 is folded under the clamping of the first folding roller 41 and the second folding roller 42, so as to form a second folding edge 54. It can be understood that by making the second folding device 40 include a first folding roller 41 and a second folding roller 42, not only the structure is simple and the cost is low, but also the second folding 54 can be processed better.

[0084] It should be noted that the first folding roller 41 and the second folding roller 42 can move along the length direction of the conveyor line 10, so as to process a second folding edge 54 of a preset length; or optionally, in one embodiment, a plurality of first folding rollers 41 and a plurality of second folding rollers 42 are respectively provided, and the plurality of first folding rollers 41 and the plurality of second folding rollers 42 are arranged at intervals along the length direction of the conveyor line 10, so that when the plate 50 moves, the plurality of first folding rollers 41 and the plurality of second folding rollers 42 can roll the second folding edge 54 multiple times, thereby enhancing the structural stability of the second folding edge 54 after folding, and preventing the second folding edge 54 from deviating from the preset folding angle due to restoring elastic deformation.

[0085] Optionally, in one embodiment, as Figure 1 As shown, the second folding device 40 is arranged between the notch processing device 20 and the first folding device 30, so that when the plate 50 is transported from the notch processing device 20 to the first folding device 30, the second folding edge 54 can be processed by the way, thereby improving the processing efficiency of the plate 50.
