[0034] In a specific embodiment of the present utility model, the upper pressing plate 6 is fixedly connected to the bottom of the cover plate 7, and the iron core can be pressed by the arrangement of the upper pressing plate 6.

[0035] Specifically, the support mechanism is arranged on the top of the lower backing plate 1. The support mechanism is used to connect the iron core. The support mechanism includes a lower fixing plate 2, a positioning ring 12, a positioning block A 14 and a positioning block B 15. The positioning ring 12 is detachably connected to the top of the lower backing plate 1 by screws. The lower fixing plate 2 is movably sleeved on the positioning ring 12, and the lower fixing plate 2 is detachably connected to the top of the lower backing plate 1 by screws. A plurality of positioning blocks A 14 are provided, and a plurality of positioning blocks A 14 are all movably inserted on the circumferential surface of the positioning ring 12, and a plurality of positioning blocks A 14 are evenly distributed.

[0036] In a specific embodiment of the present utility model, the lower fixing plate 2 is arranged to place the iron core, thereby supporting the iron core. The positioning ring 12 is arranged for positioning the iron core to prevent the iron core from shifting during curing. The positioning blocks A 14 and the positioning blocks B 15 are arranged to limit the rotation of the iron core, so as to realize the positioning of the iron core during curing.

[0037] Specifically, the elastic pressing mechanism is arranged on the support mechanism. The elastic pressing mechanism includes a cover plate 7, nuts 8, springs 9, and threaded rods 11. There are four threaded rods 11, and the four threaded rods 11 are all threadedly connected to the top of the positioning ring 12 and are evenly distributed. The cover plate 7 is movably sleeved on the four threaded rods 11. There are four nuts 8, and each nut 8 is threadedly connected to each threaded rod 11. There are four springs 9, and each spring 9 is movably sleeved on each threaded rod 11, and each spring 9 is located between each nut 8 and the cover plate 7.

[0038] In a specific embodiment of the present invention, the threaded rod 11 is provided for movably sleeving the cover plate 7. Since the cover plate 7 is movably sleeved on the threaded rod 11, the cover plate 7 can slide on the threaded rod 11. The nut 8 is provided to limit the spring 9, so that the spring 9 is restricted between the cover plate 7 and the nut 8. By rotating the nut 8, the nut 8 moves on the threaded rod 11. By moving the nut 8, the spring 9 can be compressed, so that the spring 9 is pressed tightly. By pressing the spring 9 tightly, the upper pressure plate 6 can press the cured iron core. When the entire device is placed in an oven for heating, using the pressure of the spring 9 of the tooling itself, during the heating process, pressurization is carried out while heating to achieve the purpose of iron core curing. Through this self-bonding curing tooling, the production efficiency and bonding strength of the three-in-one self-bonding electrical steel are greatly improved, and the dimensional tolerance and geometric tolerance of the iron core can also be greatly improved.

[0039] Specifically, the bracket component is arranged on the top of the lower fixing plate 2. The bracket component includes washers 3 and mounting collar rings 5. There are multiple washers 3, and the multiple washers 3 are all fixedly connected to the top of the lower fixing plate 2 and are evenly distributed.

Since the locking screw 4 is threadedly connected to the mounting collar ring 5 and the locking screw 4 can abut against the pressure measuring block 13 while rotating on the mounting collar ring 5, the pressure measuring block 13 can press the iron core.

[0043] Specifically, two lifting rings 10 are threadedly connected to the top of the cover plate 7, and the two lifting rings 10 are symmetrically arranged.

[0044] In a specific embodiment of the present utility model, the two lifting rings 10 are provided for lifting the entire device.

[0045] The working principle or working process of the self-bonding electrical steel three-in-one self-bonding curing tooling provided by the present utility model is as follows: The nut 8 is provided to limit the spring 9, so that the spring 9 is restricted between the cover plate 7 and the nut 8.
