[0030] The lower die 4 is provided with a first edge separation groove 41 and a second edge separation groove 42, and the two first edge separation grooves 41 and the two second edge separation grooves 42 form a separation groove group 46, as shown in Figure 4 , the two first edge separation grooves 41 and the two second edge separation grooves 42 enclosed by the dashed box are a separation groove group 46, the two first edge separation grooves 41 in the same separation groove group 46 are oppositely arranged, the two second edge separation grooves 42 in the same separation groove group 46 are oppositely arranged, the first edge separation groove 41 comprises an oblique groove 411, and the oblique groove 411 extends to the direction of the oblique groove 411 of the other first edge separation groove 41 in the same group;
[0031] As shown in Figure 5As shown, the lower die 4 is provided with a first edge separation block 51 and a second edge separation block 52, the first edge separation block 51 is complementary in shape to the first edge separation groove 41, correspondingly, the first edge separation block 51 includes a bevel pressing strip 511 corresponding to the bevel groove 411, and the first edge separation block 51 is directed towards the first edge separation groove 41, the second edge separation block 52 is complementary in shape to the second edge separation groove 42, and the second edge separation block 52 is directed towards the second edge separation groove 42, so as to form two corresponding first edge separation seams 31 and two corresponding second edge separation seams 32 on the metal plate 3 by a set of separation groove groups 46 and corresponding first edge separation blocks 51 and second edge separation blocks 52 in the lower die 4 as shown in Figure 3 Two corner codes are formed on the metal plate 3 as shown.
[0032] In the corner code stamping die, two first edge separation grooves 41 and two second edge separation grooves 42 in the same set of separation groove groups 46 in the lower die 4 can be matched with corresponding first edge separation blocks 51 and second edge separation blocks 52 in the lower die 4, so as to form two corresponding first edge separation seams 31 and two corresponding second edge separation seams 32 on the metal plate 3, the middle position enclosed by the two first edge separation seams 31 and the two second edge separation seams 32 is the embryo of two corner codes, in particular, the bevel groove 411 of the first edge separation groove 41 is matched with the bevel pressing strip 511 of the first edge separation block 51, so as to cut the middle position enclosed by the two first edge separation seams 31 and the two second edge separation seams 32 obliquely, so as to form two independent corner codes.

Figure 6 As shown, the two first edge separation grooves 41 enclosed by the dashed box form the first group 47, and the two second edge separation grooves 42 enclosed by the dashed box form the second group 48 in another set of separation groove groups 46.
[0034] The corner stamping die also includes a feeding module, which is used to push the metal plate 3 to be stamped multiple times to the rear side of the lower die 4 at a rated frequency and a rated stroke. The feeding module is preferably a robot. After the upper die 5 presses down on the lower die 4 and then lifts it up, the robot uses the robot to pick up the metal plate 3 and move the metal plate 3 to the rear side of the lower die 4. After moving the rated stroke, the metal plate 3 is then put down to the lower die 4. In this way, after the corresponding seam is stamped at the corresponding position of the metal plate 3, the feeding module transports the metal plate 3 to the rear side so that the corresponding seam can be stamped on the metal plate 3 by the subsequent corresponding structure of the upper die 5 and the lower die 4.

By setting the first group 47 and the second group 48 one after the other to achieve stamping in a sequential manner, the purpose is to avoid excessive pressure on the upper die 5 and the lower die 4 due to too much gap in one stamping, thereby avoiding machine damage.
[0035] Preferred, such as Figure 6 As shown, the first edge dividing groove 41 further includes a first side groove 412 and a second side groove 413. The first side groove 412 and the second side groove 413 are intersecting and connected. The oblique side groove 411 is disposed at the intersection of the first side groove 412 and the second side groove 413. Correspondingly, the first edge dividing block 51 further includes a first pressing strip 512 and a second pressing strip 513. The first pressing strip 512 is complementary to the first side groove 412 in shape, and the first pressing strip 512 faces the first side groove 412. The second pressing strip 513 is complementary to the second side groove 413 in shape, and the second pressing strip 513 faces the second side groove 413. In this way, an intersecting and connected first slit 312 and second slit 313 can be formed on the metal plate 3. The first slit 312, the second slit 313 and the oblique slit 311 form the first edge dividing groove 31.
[0036] The second edge dividing groove 42 includes a third edge groove 421 and a fourth edge groove 422, which are intersecting and connected. Correspondingly, as Figure 5As shown, the third edge dividing block includes a third pressure strip 521 and a fourth pressure strip 522.

The fourth pressure strip 522 is complementary in shape to the fourth side groove 422, and the fourth pressure strip 522 faces the fourth side groove 422. In this way, intersecting and interconnected third slits 321 and fourth slits 322 can be formed on the metal plate 3, and the third slits 321 and fourth slits 322 form the second edge dividing slit 32.
[0037] Optional, such as Figure 7 As shown, the lower mold 4 is also provided with a connecting groove 43. The two ends of the connecting groove 43 are respectively located on the same connecting line 7 connecting the ends of the inclined grooves 411 corresponding to the two first edge separating grooves 41 in the same group of separating grooves 46. The connecting line 7 is parallel to the central axis 9 of the lower mold 4 along its length. The connecting groove 43 is located behind the first edge separating groove 41. Figure 5 As shown, the upper mold 5 is also provided with a connecting pressure strip 53. The shape of the connecting pressure strip 53 is complementary to the shape of the connecting groove 43, and the connecting pressure strip 53 faces the connecting groove 43.
[0038] In this embodiment, the two ends of the connecting groove 43 are the left end and the right end of the connecting groove 43, respectively. The left end of the connecting groove 43 is connected to the end of the oblique groove 411 corresponding to the first edge dividing groove 41 on the left side in the same group of dividing grooves 46 by the same line 7. The right end of the connecting groove 43 is connected to the end of the oblique groove 411 corresponding to the first edge dividing groove 41 on the right side in the same group of dividing grooves 46 by the same line 7. In this way, by feeding the metal plate 3 through the feeding module, a connecting seam 33 can be formed between the two oblique openings 311 of the metal plate 3, thereby connecting the two oblique openings 311 and separating the two corner brackets.
[0039] Specifically, such as Figure 8 As shown, the lower die 4 further includes a bending support inclined block 44, which is inclined away from the upper die 5 to form an inclined surface. The bending support inclined block 44 is located behind the connecting groove 43; Figure 5 As shown, the upper mold 5 also includes a bending pressure block 54, the shape of which is complementary to the shape of the bending support inclined block 44, and the bending pressure block 54 faces the bending support inclined block 44.

The first connecting plate 1 is located on the horizontal plane, and the second connecting plate 2 is formed on the inclined surface.
[0040] It is worth noting that, such as Figure 2As shown, the lower die 4 further comprises an angle code separation groove 45 which is located in the same straight line 8 as the first edge separation groove 41 and / or the second edge separation groove 42, the straight line 8 being parallel to the central axis 9 of the length direction of the lower die 4; the angle code separation groove 45 is located at the rear side of the bending support inclined block 44; as shown, Figure 5 As shown, the upper die 5 further comprises a split pressing block 55 which is complementary in shape to the angle code separation groove 45 and faces the angle code separation groove 45.
[0041] In the present embodiment, there are at least two types of angle code separation grooves 45, the first type of angle code separation groove 45 being located away from the central axis 9 of the lower die 4, and the second type of angle code separation groove 45 being located at the central axis 9 of the lower die 4. Since the metal plate 3 will form two independent angle codes after passing through the first edge separation groove 41, the second edge separation groove 42 and the connecting groove 43, in order to ensure that the angle codes will not be separated from the metal plate 3 during the conveying process by the feeding module, the angle codes will be allowed to retain some connection parts with the metal plate 3, and at the last side of the lower die 4, the angle codes will be completely separated from the metal plate 3 by the angle code separation groove 45 and the split pressing block 55, and the angle codes can also be seen from the last side of the lower die 4. Figure 3 As shown from the last side of the lower die 4, the metal plate forms four independent angle codes by the two groups of separation groove groups 46. Specifically, the angle code separation groove 45 is located in the same straight line 8 as the first edge groove 412 of the first edge separation groove 41, or the angle code separation groove 45 is located in the same straight line 8 as the third edge groove 421 of the second edge separation groove 42, so that it is not necessary to use an alignment mechanism additionally in the subsequent process, and the position to be punched can be accurately identified, so that the angle codes are completely separated from the metal plate 3.
