The punch 4 is positioned right above the cavity groove 24, and the punch 4 can be inserted into the cavity groove 24.

As shown in figure 3, when the male die 4 is inserted into the cavity groove 24, the outer wall of the male die 4 and the inner wall of the female die 3 (namely the inner wall of the cavity groove 24) just clamp the edge flanging of the partition board 1.

As shown in fig. 3, the male die 4 is sleeved with a mounting plate 19 and a discharging plate 17, the mounting plate 19 is positioned between the upper die plate 16 and the discharging plate 17, and the mounting plate 19 is detachably connected with the upper die plate 16 through screws. The mounting plate 19 is fixed to the outer wall of the male mould 4 and the stripper plate 17 can move up and down against the outer wall of the male mould 4.

As shown in FIG. 2, the mounting plate 19 has a circular hole 20, a spring 18 is disposed in the hole 20, one end of the spring 18 is connected to the lower surface of the upper plate 16, and the other end of the spring 18 is connected to the upper surface of the stripper plate 17. The upper template 16 is connected with the lower template 21 through a guide pair 25, the guide pair 25 is perpendicular to the upper template 16 and the lower template 21, and the central axis of the guide pair 25 is parallel to the central axis of the spring 18.

As shown in fig. 2, a top rod 22 penetrates through the lower template 21, and the central axis of the top rod 22 is also parallel to the central axis of the guide pair 25. A first material supporting plate 5 and a second material supporting plate 6 are arranged in the concave die 3 and are perpendicular to the ejector rod 22, and the ejector rod 22 is directly and fixedly connected with the second material supporting plate 6. The second material supporting plate 6 supports the first material supporting plate 5, and the second material supporting plate and the first material supporting plate are detachably connected through screws.

As shown in fig. 2, the first retainer plate 5 has a circular positioning hole 7 and a circular second positioning hole 8, and the second retainer plate 6 has a circular third positioning hole 9. The upper surface of the first material supporting plate 5 is provided with a first positioning block 11, a first positioning column 10 is coaxially fixed on the first positioning block 11, and the first positioning column 10 is inserted into the second positioning hole 8 in a matching manner. A second positioning block 13 is placed in the positioning hole 7, the top surface of the second positioning block 13 needs to extend out of the upper surface of the first material supporting plate 5, a second positioning column 12 is coaxially fixed on the second positioning block 13, and the second positioning column 12 is inserted into the third positioning hole 9 in a matching manner.

The first positioning column 10 can be separated from the second positioning hole 8 and the second positioning column 12 can be separated from the third positioning hole 9 by a lifting method of a hand or an electromagnet. Before flanging the edge of the formed partition plate 1, one round hole 2 on the material plate is flanged and sleeved on the first positioning block 11, and the other round hole 2 is flanged and sleeved between the second positioning block 13 and the positioning hole 7.

As shown in fig. 3, the punch 4 includes a first circular cavity 14 formed to escape from the first positioning block 11 and turned up around the first positioning block 11, and a second circular cavity 15 formed to escape from the second positioning block 13.

The diameters of the first positioning block 11 and the second positioning block 13 are both larger than the maximum diameter of the circular holes 2 on the partition boards 1 of all specifications, and the first circular cavity 14 and the second circular cavity 15 on the male die 4 only need to be designed according to the sizes of the first positioning block 11 and the second positioning block 13. When the size of the circular hole 2 of the produced separator 1 is reduced, only the first positioning block 11 and the second positioning block 13 with corresponding sizes are needed to be used.

The implementation principle of the embodiment is as follows: when the female die 3 and the male die 4 move towards each other, the female die 3 and the stripper plate 17 clamp the edge of the material plate (the partition plate 1 which is not flanged) firstly, then the female die 3 continues to push the stripper plate 17, the spring 18 is compressed, the male die 4 is slowly inserted into the female die 3 at the moment, the edge of the material plate clamped by the female die 3 and the stripper plate 17 is pushed into the female die 3 by the male die 4, and finally the flange is formed. After the flanging of the partition plate 1 is finished, the female die 3 is separated from the discharging plate 17, the partition plate 1 tightly sleeved on the male die 4 is separated from the female die 3, immediately the spring 18 pushes the discharging plate 17 to return to the original position, and the discharging plate 17 pushes the partition plate 1 clamped on the male die 4 away from the male die 4, so that the discharging is finished.

According to the size of the round hole 2 on the partition board 1, the first positioning block 11 and the second positioning block 13 with the same size are selected to position the partition board 1, then the female die 3 and the male die 4 move oppositely, and the male die 4 is inserted into the female die 3, so that the material plate can be flanged to form the partition board 1. When the partition boards 1 of different specifications need to be formed, the first positioning block 11 and the second positioning block 13 which correspond to the circular holes 2 on the partition board 1 in size are used instead, and the purpose of flanging the partition boards 1 of all specifications by using one set of flanging die is achieved.

The function of the ram 22: if the distance between the upper surface of the first retainer plate 5 and the top surface of the female die 3 is far greater than the flanging height, the spring 18 is excessively compressed during the flanging forming, so that the service life of the spring 18 is reduced; even in the case where the spring 18 has been compressed to the minimum and the punch 4 has not yet been inserted into the bottom of the cavity 3, the formation of the burring cannot be completed. In order to solve the problem, the ejector rod 22 is firstly used for ejecting the second retainer plate 6, so that the depth of the upper surface of the first retainer plate 5 from the top surface of the female die 3 is equal to the height of the flanging, then the female die 3 is used for pressing the discharging plate 17 so that the male die 4 is inserted into the female die 3, and the compression range of the spring 18 is designed to be larger than the height of the flanging.

As shown in fig. 2, the transition of the top surface of the concave die 3 to the inner wall of the concave die 3 has a round corner 23, and the design has the advantages that: at the beginning, the top surface of the female die 3 and the stripper plate 17 clamp the edge of the flitch firstly, and the edge of the flitch is gradually pressed into the female die 3 by the male die 4 along with the insertion of the male die 4 into the female die 3; when the edges of the flitch are dragged on the surface of the female die 3, if the transition part between the top surface of the female die 3 and the inner wall of the groove is a sharp corner, the flitch can be scratched, so that the formed flanging has scars or is thinned, and the fillet 23 can solve the problem.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
