[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0025] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0026] In some embodiments of the present invention, Figure 1-Figure 3 As shown, a multi-wedge interactive flanging die is provided, comprising a plurality of arc-shaped lower die bases 100. Each of the lower die bases 100 is provided with a die cavity 200 and an angled wedge mechanism 300. The angled wedge mechanism 300 is installed inside the die cavity 200. The lower die base 100 is provided with at least one connecting bevel 400. The inclination angles of the connecting bevels 400 of the lower die base 100 are different from each other. The lower die bases 100 are connected in sequence through the connection of the connecting bevels 400, thereby forming a larger arc-shaped die base.

[0027] Specifically, in some embodiments, the lower portion of the lower die base 100 protrudes outward to form a bump 110 , two sides of the bump 110 approach each other outward from the lower die base 100 , and the side surface of the bump 110 is the connecting slope 400 .

[0028] It should be noted that the angle between two adjacent lower mold bases 100 is in the range of 0°-30°. Therefore, the gap between two adjacent lower mold bases 100 is in a certain range. The wheel cover placed on the lower mold base 100 separated by a certain angle can still get sufficient support even though part of the wheel cover is not in contact with the lower mold base 100. In some other embodiments, when the angle between the two lower mold bases 100 is greater than 30°, some fillers (such as rubber blocks, etc.) can be placed in the gap between the two adjacent lower mold bases 100 to strengthen the support for the wheel cover.

[0029] The utility model connects different lower mold bases 100 to each other to construct mold bases of different sizes. The circumference of the mold base is related to the number of the lower mold bases 100 participating in the combination. The more the lower mold bases 100 participating in the combination are, the longer the circumference of the mold base is. By using the mold base, the wheel cover can be subjected to segmented fine flanging processing, that is, the wheel cover is divided into multi-end arc parts, each arc section is sequentially placed in the mold base, and the wheel cover section is subjected to flanging processing or flanging repair of different lengths by stamping, thereby avoiding the problem of poor flanging processing effect.

[0030] In other embodiments of the present invention, the connecting slope 400 is disposed on the lower side of the lower die base 100, the connecting slope 400 is a plane, and the connecting slope 400 is provided with a magnetic attraction mechanism 500, and the magnetic attraction mechanism 500 enables the two lower die bases 100 to attract each other. Through the magnetic attraction mechanism 500, each lower die base 100 can be quickly connected.

[0031] In other embodiments of the utility model, an alignment structure (not shown) is provided on the connecting inclined surface 400. In some preferred embodiments, the alignment structure is a positioning column and a positioning hole. By inserting the positioning column into the positioning hole, the two lower mold bases 100 can be quickly aligned. With the attraction of the magnetic suction mechanism 500, the connection between the lower mold bases 100 can be made more convenient, and the connection efficiency between the lower mold bases 100 can be improved.

[0032] In other embodiments of the present invention, Figure 1-Figure 2 As shown, the magnetic attraction mechanism 500 is an electromagnet 510. Specifically, when the lower mold base 100 needs to be connected, the electromagnet 510 is energized to generate magnetism. After the lower mold bases 100 are brought close to each other, the electromagnets 510 attract each other and the lower mold bases 100 are automatically connected together.

[0033] In other embodiments of the present invention, Figure 1-Figure 3 As shown, the connecting bevels 400 are all L-shaped. Specifically, the connecting bevels 400 are set to be L-shaped, and when the lower mold bases 100 are connected to each other, the bottom and the top of the lower mold base 100 can be effectively fixed, so that the connection between the lower mold bases 100 is more stable.

[0034] In other embodiments of the present invention, Figure 1-Figure 2 As shown, the wedge mechanism 300 includes a slider 310. The slider 310 is provided with a horizontal guide surface 311, a first oblique guide surface 312, a vertical guide surface 313 and a driving connection inclined surface 400. The first oblique guide surface 312 is arranged at the top of the vertical guide surface 313, and the first oblique guide surface 312 and the vertical guide surface 313 are respectively arranged at the front end of the horizontal guide surface 311. Specifically, when the ram (not shown) of the punching machine moves downward and contacts the slider 310. The slider 310 is squeezed by the ram and slides to one side. The first oblique guide surface 312 can provide a buffer for the ram to prevent the slider 310 from being damaged by the huge impact force of the ram. The first oblique guide surface 312 and the vertical guide surface 313 cooperate with each other, and can guide the ram during the descent of the ram, so that the ram can descend vertically smoothly and fall into the mold cavity 200.

[0035] In other embodiments of the present invention, Figure 1-Figure 2 As shown, an extension block 120 is provided at the upper end of the lower die base 100. The extension block 120 is opposite to the vertical guide surface 313, and a second oblique guide surface 121 is provided on the extension block 120.

[0039] In other embodiments of the present invention, Figure 1-Figure 3 As shown, guide grooves 330 are provided on both sides of the slider 310. A guide block 150 is provided at the upper end of the lower die base 100. The guide block 150 is slidably installed in the guide groove 330. Specifically, the guide block 150 and the guide groove 330 are provided to further increase the stability of the slider 310 when sliding, and also make the slider 310 slide more smoothly.
