For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0033] This embodiment records a modular structure for the positive shaping of the side outer panels that is compatible with the trial production of multiple vehicle models, and its upper mold base can be repeatedly recycled, which can greatly reduce the production cost.

[0034] The positive modular structure of this embodiment adopts the left and right combination method to simultaneously develop and manufacture the side outer panels on the left and right sides of the new model, which can reduce the width of a single-piece mold by 25%.

[0035] The internal area of ​​the positive shaping modular structure is divided into a modeling area and a shaping area. When designing and developing a new vehicle model, the universal structure of the vehicle side outer panel is set in the modeling area, and the shaping structure of the side outer panel related profile selected by the previous CAE formability analysis is set in the shaping area. In this embodiment, the universal structure can be composed of a plurality of modular structures. Through different combinations of a plurality of modular structures, different universal structures of different vehicle models can be formed, which can increase the applicability of the positive shaping modular structure. The shaping structure is composed of a positive shaping structure and a non-shaping structure. The positive shaping structure is generally: the profile structure of the door sill, the taillight end, the rear fender brow area and the fuel filler port. The non-shaping structure is the support, connection and other structures of the positive shaping structure, which is mainly composed of the profile support positioning structure and the hollow structure, which can greatly reduce the weight of the entire side outer panel.

[0036] like Figure 1 As shown, the positive modular structure is mainly composed of an upper die 1 and a lower die punch 2. Both the upper die 1 and the lower die punch 2 are left-right symmetrical structures and match the side outer panels on the left and right sides of the new model. The side outer panels on the left and right sides of the new model are simultaneously produced by stamping the lower die punch 2 with the upper die 1.

[0037] like Figures 2 to 4 As shown, the upper die 1 is composed of an upper die universal frame 3, an upper die pressing plate 4, and a shaping knife block 5.

[0038] The upper mold universal frame 3 is a supporting base for the upper mold 1, and its inner cavity area includes a modeling area and a shaping area. One end of the inner cavity of the upper mold universal frame 3 has an opening facing the lower mold punch 2, and a plurality of guide mounting columns connected to the lower mold punch 2 are provided on the end face of the upper mold universal frame 3 at the opening end. Preferably, the plurality of guide mounting columns are symmetrically arranged on the end face of the upper mold universal frame 3 along the axis of the upper mold universal frame 3 to ensure a stable connection between the upper mold 1 and the lower mold punch 2, thereby ensuring the accuracy of the side outer panel produced by stamping.

[0039] In addition, a plurality of mounting surfaces and contact surfaces are respectively provided on the end surface and the inner side of the upper die universal frame 3, for cooperating with the mounting of the upper die pressing plate 4 in the upper die universal frame 3. The mounting surfaces and contact surfaces of this embodiment are manufactured by full-plane processing, which can meet the flexible adjustment and installation of the shaping blade block 5 in different shaping areas of different models, so as to take into account the positive shaping of the side outer panels of multiple models.

[0040] The upper die pressing plate 4 is placed in the molding area in the upper die universal frame 3 and is fixed to the upper die universal frame 3 by screw locking. The structural shape of the upper die pressing plate 4 is the universal structural shape of the vehicle model. The upper die pressing plate 4 has a through hole that matches the shaping area and passes through from top to bottom. The shaping blade block 5 is set in the through hole in the shaping area and is used to cooperate with the lower die punch 2 during the stamping process to stamp the process material of the side outer panel according to the shaping area to obtain the shaped surface structure.

[0041] The multiple shaping blade blocks 5 of this embodiment can be flexibly adjusted in position in the shaping area and installed on the upper mold universal frame 3. For example, if the shaping structure is a long surface, a long hole matching the long surface is provided in the upper mold pressing plate 4; the shaping blade block 5 is composed of a shaping block 6 and a shaping blade block base 7. One or more shaping blocks 6 are installed on the shaping blade block base 7 according to the shape of the shaping structure. The bottom of the shaping block 6 is connected to the shaping blade block base 7, and the shaping blade block base 7 is locked to the upper mold universal frame 3 by screws; or the shaping structure is a small surface, and a separate shaping blade block 5 is made according to the appearance of the shaping structure, and the shaping blade block 5 is directly fixed to the shaping area of ​​the upper mold universal frame 3 by screws.

[0042] In order to ensure the positioning and installation of the upper die pressing plate 4 on the upper die universal frame 3, the upper die pressing plate 4 of this embodiment is fixed on the upper die universal frame 3 by guiding and pressing plate positioning. Preferably, multiple guide sliding surfaces 11 and pressing plate surfaces 12 are provided on each outer side of the upper die pressing plate 4. There is a predetermined interval between the upper die pressing plate 4 and the upper die universal frame 3, and multiple guide blocks 9 are symmetrically embedded in the interval on the left and right sides of the upper die pressing plate 4. One side of the guide block 9 is connected to the guide sliding surface 11, and the other side is connected to the contact surface on the inner side of the upper die universal frame 3. When installing the upper die pressing plate 4, the guide block 9 can be guided and moved relative to the upper die universal frame 3 to adjust the position of the upper die pressing plate 4. The upper die pressing plate 8 is installed on the installation surface of the upper die universal frame 3 by screws, and the inner side end of the upper die pressing plate 8 extends to the upper die pressing plate 4 and is pressed on the pressing plate surface 12, which is used to limit the upper die pressing plate 4 to prevent it from detaching from the upper die universal frame 3 during the stamping process. Preferably, the pressure plate surface 12 is arranged at the bottom end of the groove arranged on the outside of the upper mold pressing plate 4, and the inner side of the upper mold pressing plate 8 is not only pressed on the pressure plate surface 12, but also embedded in the groove. The positioning connection between the upper mold pressing plate 4 and the upper mold universal frame 3 can be enhanced through the groove and the upper mold pressing plate 8, which can ensure the stability and accuracy of the surface shaping during stamping.

[0043] Conical balancing weights 10 are symmetrically arranged on the front and rear outer sides of the upper die pressing plate 4, and the plurality of conical balancing weights 10 are symmetrical on both sides of the axis of the upper die pressing plate 4. The top center of the conical balancing weight 10 has a conical hole which is coaxial with the conical balancing weight 10 and gradually increases in diameter toward the opening direction. Figure 5 As shown, a conical block 13 matching the conical balancing block 10 is provided on the lower die punch 2, and the upper center of the conical block 13 has a conical structure coaxial with the conical block 13 and gradually shrinking toward the upper die 1. When the upper die 1 is punched toward the lower die punch 2, the conical balancing block 10 is coaxially sleeved on the conical block 13 through the conical hole, and gradually sleeved on the conical structure of the conical block 13 through the conical hole of the conical balancing block 10, guiding the upper die 1 to adjust the punching direction and continue to press down steadily, which can ensure the accuracy of the side outer panel after punching.

[0044] The process of producing the side outer panel using the positive modular structure of this embodiment is:

[0045] First, according to the CAE formability analysis, the shaping blade 5 is installed in the shaping area of ​​the upper die universal frame 3, and then the upper die pressing plate 4 is guided, positioned and locked in the upper die universal frame 3. The material is placed on the lower die punch 2, and according to the set stamping parameters, the upper die 1 punches the material to the lower die punch 1, and the shaping blade 5 punches the material in the positive shaping area to make the side outer panel. During the stamping process, the guide installation column on the upper die universal frame 3 gradually embeds into the guide groove set on the lower die punch 2, and the conical balancing block 10 gradually fits on the conical block 13, guiding the upper die 1 to accurately press the lower die punch 2, ensuring that the positive shaping modular structure is stable, reliable, and accurate in producing the side outer panel.
