The concave die is formed by encircling four magnetic material blocks and four non-magnetic material blocks, and the magnetic material blocks and the non-magnetic material blocks are arranged at intervals. The female die is surrounded by two magnetic conduction material pieces and four non-magnetic material pieces, and the magnetic conduction material pieces and the non-magnetic material pieces are arranged at intervals. The concave die is an annular body made of magnetic conductive materials. The upper punch is fixed on the movable cross beam through a pressing block. And a heating mechanism for heating the female die is also arranged on the rack and is connected with a temperature control system. The multi-polar orientation and radiation orientation multifunctional magnetic field press has the advantages that: has the functions of a multi-polar orientation magnetic field and a radiation orientation magnetic field press, and is a multifunctional magnetic field press. The press can be used for manufacturing anisotropic multi-pole magnetic rings and anisotropic radiation magnetic rings, so that the comprehensive production capacity of equipment is improved, and the cost is saved. The structure that the lower cross beam is fixed with the lower punch is that the lower cross beam and the lower punch are spliced together through splicing equipment, the lower cross beam is cuboid, the lower punch is cuboid, the splicing equipment comprises a splicing part and a splicing section, the bottom of the splicing part 2 is adhered to the top wall of the lower cross beam through an adhesive, and the splicing part comprises a plate-shaped main body 22 and a pair of splicing plates 23. Here, the coupling port 222 is provided on the top wall of the plate-like body 22; specifically, the plate-like body 22 may have a rectangular parallelepiped shape or a square shape, and the coupling opening 222 may have a rectangular parallelepiped shape or a square shape and penetrate through the plate-like body 22. The pair of plugboards 23 may be rectangular or square and arranged opposite to each other, one side wall of each plugboard 23 is connected with the inner surface of the corresponding coupling port 222, and the other side wall of each plugboard 23 is a suspended side; the pair of insertion plates 23 are bent outward of the plate-like body 22 with a predetermined gap between their facing free sides.

In practical applications, the plate-shaped body 22 and the plug portion 2 can be integrally formed by pressing to increase the damage resistance. Here, the pair of plugging plates 23 have a preset thickness, so that the pair of plugging plates 23 can be bent in a certain radian with respect to the plate-shaped main body 22 to change the preset interval between the opposite suspended sides of the pair of plugging plates 23; the larger the thickness of the pair of plugboards 23 is, the greater the combining action between the pair of plugboards 23 after plugging is, however, the smaller the interval amplitude which can be changed between the opposite hanging sides of the pair of plugboards 23 is; conversely, the smaller the thickness of the pair of plugboards 23, the smaller the combined effect between the plugboards 23 after plugging, but the larger the spacing amplitude that can be changed between the opposite suspended sides of the pair of plugboards 23.
