In this embodiment, the tray 1 has a plate-like structure with a flat supporting surface, so that the lower template 2 can be placed on the tray 1; the pallet 1 can also attract magnets, and the pallet 1 is preferably made of carbon structural steel (Q235), so that the pallet can attract magnets and can bear pressure due to high hardness. Any material that can absorb the magnet and has high hardness may be used as the material for manufacturing the tray 1, and is not limited herein. In addition, one side of the edge of the tray 1 extends upwards to form a bending end 11, and the bending end 11 is mainly convenient for operators to push and pull the tray 1.
In the present embodiment, the lower die plate 2 and the upper die plate 3 are each formed by arranging a plurality of molding strips 6 of at least one specification, in other words, when arranging the lower die plate 2 and the upper die plate 3, depending on the actual use, a plurality of molding strips 6 of one specification may be used, or a plurality of molding strips 6 of a plurality of specifications may be used. The specifications of the bead 6 in the present application are different, but the height of the bead 6 is the same. Therefore, when the pressing strips 6 are arranged as the lower template 2 or the upper template 3, a stress surface with uniform height can be formed, so that the functions of force transmission and avoidance are achieved.
Preferably, the molding compound (SMC) of the present application is used to form the molding compound (6), which includes several rectangular structures with the same height and multiple rectangular solids with different lengths and widths (it should be noted that the material and shape of the molding compound (6) are not limited to one material or shape provided by the present application).
Preferably, considering that the lower die plate 2 formed by the pressing strips 6 has a risk of moving in the turnover process, the pressing strips 6 can be embedded with magnets, so that the pressing strips 6 have certain magnetism and can be adsorbed on the tray 1, the lower die plate 2 is detachably adsorbed on the tray 1 through the limit between the self magnetic force and the tray 1, namely, the pressing strips 6 can be fixedly adsorbed on the tray 1 through the magnets and can be moved or removed from the tray 1. Preferably, as shown in fig. 3 and 4, a molding structure of one specification of the present application is provided, in which four magnet bottom holes 61 are provided on the lower surface of each molding 6, and a magnet (not shown) is embedded in each magnet bottom hole 61. Therefore, the lower template 2 formed by combining a plurality of pressing strips 6 can be adsorbed on the tray 1 through four magnets at the bottom of the pressing strips 6.
Because the lower template 2 and the upper template 3 in the application are formed by arranging a plurality of pressing strips 6 with different specifications, preferably, the application can arrange the lower template 2 which meets the assembly of most of the busbar 4 only by using the pressing strips 6 with few specifications, therefore, when the lower template is arranged at the beginning, the pressing strips 6 with proper sizes are required to be selected for arrangement according to the size factors, avoiding positions and other size factors of the busbar 4, and in the embodiment, preferably, as shown in fig. 5, graduation marks 62 are printed on the upper surface of the pressing strips 6 along the length direction. When the pressing strips 6 form the lower template 2 or the upper template 3, the positions and the intervals of the pressing strips 6 are marked on the drawing, the pressing strips 6 with proper sizes can be quickly selected through the scale marks 62 of the pressing strips 6, a plurality of pressing strips 6 can be quickly positioned at a certain position on the tray 1 to be assembled into the lower template 2, the relative positions of the pressing strips can be referred to, the arrangement of operators is facilitated, and the operation is simple and quick. In addition, the space 21 is reserved on the lower die plate 2 composed of the pressing strips 6, preferably, as the upper surface and the lower surface of the assembled busbar 4 are provided with at least one protrusion 41, the positions and the number of the space 21 are matched with those of the protrusions 41 on the busbar component 4, in the embodiment, as long as the size of the space 21 can accommodate the protrusions 41, the busbar 4 can be attached on the upper surface of the lower die plate 2 in parallel, the inner wall of the space 21 does not need to be completely attached to the outer wall of the protrusion 41, and therefore, the requirement on the size precision is low, and the operation of operators is more convenient.
In this embodiment, as shown in fig. 6, two parts of the busbar 4 to be assembled are required to be stacked according to the drawing requirement, and because the relative positions of the two parts of the busbar 4 to be bonded have the precision requirement, the two parts of the busbar 4 need to be positioned by using the positioning plate 5, and as shown in fig. 6, positioning holes are formed in the combined protrusions 41 of the busbar 4, as shown in fig. 7, pin holes are formed in the positioning plate 5, detachable positioning pins 51 are arranged in the pin holes, the positioning pins 51 are riveted into the corresponding pin holes according to the positions of the positioning holes of the protrusions 41 on the busbar, and then the positioning pins 51 are inserted into the positioning holes of the protrusions 41 from the upper surface of the busbar 4, so that the positioning between the two parts of the busbar 4 is realized, and the two parts of the busbar 4 are prevented from being relatively displaced during pressing.
Preferably, the positioning plate 5 is made of stainless steel and is therefore not easily deformed during positioning, so as to ensure that the two busbar 4 do not move relative to each other (the material of the positioning plate 5 is not limited). In addition, the positioning plate 5 can be in a U shape, an I shape or an F shape according to the positions of the positioning holes of the protrusions 41 on different busbar 4.

The upper template 3 is not attached to the upper surface of the busbar 4 in the largest area as far as possible as the lower template 2, and only the pressing strips 6 are uniformly arranged on the upper surface of the busbar 4, so that the upper surface of the busbar 4 is uniformly stressed when the busbar 4 is pressed, the using amount of the pressing strips 6 is saved, and the production cost and the operation cost are reduced.
Further, as shown in fig. 1, in this embodiment, a buffer layer 7 is further provided between the tray 1 and the lower die plate 2, and preferably, the buffer layer 7 is made of a flexible material such as silicone rubber, and the thickness of the buffer layer 7 is 1-2mm and is laid flat on the tray 1.
