DETAILED DESCRIPTION

[0017] The present invention will be further described below by way of examples and in conjunction with the accompanying drawings:

[0018] like Figure 1-3 As shown, a multi-coil array electromagnetic forming device based on modular coil units is mainly composed of a workbench 1, at least one coil mounting plate 2, and at least one coil unit. A fixture or placement table for the part to be formed is placed on the workbench, and the coil mounting plate 2 is arranged on the front, back, left, right, or top surface of the workbench 1. When the coil mounting plate needs to be directly mounted on the top surface, the coil mounting plate is configured as an L-shaped plate. At least one coil unit is mounted on the coil mounting plate 2 via the same movable assembly, and the coil unit is mounted on the movable assembly via a pluggable structure. At the same time, the movable assembly not only adjusts the distance between adjacent coil units, but also adjusts the moving distance of all coil units.

[0019] The specific installation surface of the coil mounting plate is specifically set according to the required forming parts. When coil mounting plates with coils are set on two adjacent sides, the parts can be flanging, and when coil mounting plates with coils are set on two opposite sides, two parts can be welded.

[0020] The coil unit includes a coil insulating plate 3 for fixing the coil and a first connecting shaft 4 arranged on the moving component. A second connecting shaft 5 for inserting the first connecting shaft 4 is provided at one end of the coil insulating plate 3 facing the coil mounting plate 2, and a quick-insert structure is provided between the first connecting shaft 4 and the second connecting shaft 5. A coil facing the part is provided on the coil insulating plate.

[0021] The coil 8 can be configured as a single-turn or multi-turn disc coil parallel to the coil insulating plate 3, or as a single-turn or multi-turn spiral coil extending spirally in a direction perpendicular to the coil insulating plate 3, and the multi-turn spiral coil can be configured inside and outside according to the diameter size, such as Figure 3 To facilitate the fixation of the coil, a fixing column for fixing the coil is provided on the coil insulating plate, and the coil and the coil insulating plate are integrally injection molded.

[0022] The quick-connect structure includes an arc-shaped protrusion 4a on the outer wall near the end of the first connecting shaft 4, an arc-shaped groove 5a on the inner wall near the end of the second connecting shaft 5, and a connecting groove on the inner wall of the end of the second connecting shaft 5 for connecting the arc-shaped groove 5a with the end face of the second connecting shaft 5. The connecting groove matches the arc-shaped protrusion 4a. When the first connecting shaft 4 is inserted into the second connecting shaft 5, the arc-shaped protrusion 4a enters the arc-shaped groove 5a along the connecting groove. After rotating the first connecting shaft 4 or the second connecting shaft 5, the arc-shaped protrusion 4a cannot leave the connecting groove, thus achieving a quick connection between the first connecting shaft 4 and the second connecting shaft 5.

[0023] In order to achieve conductivity of the coil and ensure that there is no leakage of electricity, the first connecting shaft 4 and the second connecting shaft 5 are both set as insulating parts. At the same time, a conductive rod 6 is set in the first connecting shaft 4, and the end of the conductive rod 6 away from the coil mounting plate 2 is provided with a conductive end 6a after exceeding the first connecting shaft 4, that is, the end of the conductive rod facing the second connecting shaft is set as the conductive end, and a circle of several conductive springs 7 for close contact with the conductive end 6a is embedded in the second connecting shaft 5. All conductive springs 7 are connected to the conductive wire located in the second connecting shaft 5, and the other end of the conductive wire is connected to the coil 8 through the coil connecting wire located on the coil insulating plate 3.

[0024] Preferably, the conductive end is configured as a tapered segment with a groove between the tapered segment and the main body of the conductive rod. The maximum outer diameter of the tapered segment is larger than the inner diameter formed between all the conductive springs, ensuring contact between the conductive segment and the conductive springs. The conductive rod is made of silver-plated copper, and the wire springs utilize a multi-petal copper alloy clamping structure. High-current, low-impedance connection is achieved through elastic deformation of the conductive end and the conductive springs.

[0025] In order to increase the types of formed parts, a universal adjustment member 9 for adjusting the angle of the coil insulation plate 3 is provided between the second connecting shaft 5 and the coil insulation plate 3, and a set screw 10 for fixing the adjustment angle is provided on the universal adjustment member 9.

[0026] The moving assembly includes a fixed guide rail 11 arranged on the coil mounting plate 2, and a moving guide rail 15 perpendicular to the fixed guide rail 11 is arranged on the fixed guide rail 11 through a first moving block 14. In order to ensure that the position of the moving guide rail can be fixed after moving into place, a first fixed structure for fixing the position of the moving guide rail 15 is provided between the first moving block and the fixed guide rail 11 14. A second moving block 16 is provided in the moving guide rail 15, and the coil unit is movably arranged in the moving guide rail 15 through the second moving block 16, and a second fixed structure for fixing the position of the coil unit is provided between the second moving block 16 and the moving guide rail 15. Through the arrangement of the fixed guide rail and the moving guide rail, the coil unit can be moved in two directions on the corresponding coil mounting plate. Preferably, the moving guide rail adopts a C-type guide rail and the second moving block adopts a T-type block.

[0027] The first and second fixing structures have the same structure, both including an elastic pin 17. Correspondingly, the movable guide rail 15 or the fixed guide rail 11 has a fixing hole, and the first movable block 14 and the second movable block 16 have a fixing hole. When the elastic pin 17 passes through the fixing hole and then inserts into the fixing hole, the corresponding movable block can be fixed. Of course, the fixing structure can also adopt other structures, such as a strip groove provided on the guide rail, and locking is achieved by passing a bolt through the strip groove and the movable block.
