Description

Technical Field

[0001] This article belongs to the technical field of stamping dies for camera covers Background Art

[0002] The camera is an essential and important component in electric vehicles. It provides monitoring of the internal and external environments for traffic accident analysis and ensures the safety of vehicle driving. The power source of the camera is the distribution box. The distribution box consists of an upper and a lower cover outside and a PCBA control board inside. The PCBA control board is fixed on the lower cover, as Figure 1 and Figure 2 shown. After the upper and lower covers are combined, they are installed on the vehicle

[0003] For the production of the upper and lower covers' dies, since there are many product bends and bolts need to be riveted, each requires seven processes to be completed, that is, 7 sets of engineering dies are needed for each

[0004] The large number of product processing processes results in a large number of dies

[0005] The processes for the upper cover are: 1. Making convex hulls, 2. Blanking and punching, 3. Folding Z-shaped bends, 4. Flanging and bending, 5. Folding V-shaped bends, 6. Punching, 7. Riveting. Seven sets of dies need to be made for the upper cover

[0006] The processes for the lower cover are: 1. Blanking, 2. First-stage bending, 3. Second-stage bending, 4. Third-stage bending, 5. Fourth-stage bending, 6. Punching, 7. Riveting. Seven sets of dies need to be made for the lower cover

[0007] For the production of the upper and lower covers' dies, a total of 14 sets of dies are needed, and the production cost is relatively high. The product has a 1:1 ratio, so more machine tools are occupied during production, and the labor cost is also correspondingly high Utility Model Content

[0008] To solve the above problems, this paper proposes a stamping die for the upper and lower covers of a camera used in an electric vehicle. The stamping die includes an upper cover die and a lower cover die. The stamping process of the upper cover die successively includes embossing, blanking and punching, Z-shaped bending, flanging and bending, V-shaped bending, punching, and riveting. The stamping process of the lower cover die successively includes blanking, first-stage bending, second-stage bending, third-stage bending, fourth-stage bending, punching, and riveting. The upper cover die and the lower cover die are combined and connected in a parallel manner. The blanking and punching, Z-shaped bending, flanging and bending, V-shaped bending, blanking, first-stage bending, second-stage bending, third-stage bending, fourth-stage bending, punching, and riveting in the upper cover die and the lower cover die are respectively combined into an integrated die. The embossing of the upper cover is the first die. The blanking and punching of the upper cover and the blanking of the lower cover are an integrated second sub-die. The Z-shaped bending of the upper cover and the first-stage bending of the lower cover are an integrated third sub-die. The flanging and bending of the upper cover and the second-stage bending of the lower cover are an integrated fourth sub-die. The V-shaped bending of the upper cover is an independent fifth sub-die. The third-stage bending and the fourth-stage bending of the lower cover are an integrated sixth sub-die. The punching of the upper cover and the punching of the lower cover are an integrated seventh sub-die. The riveting of the upper cover and the riveting of the lower cover are an integrated eighth sub-die. In this way, only 8 dies are required to complete the production of the product for the upper and lower cover dies, significantly reducing the costs of die development, labor allocation, machine tools, etc.

[0009] The upper cover die and the lower cover die are linkage dies that move horizontally and transversely. Both the upper and lower sides of the upper cover die and the lower cover die are connected to a stamping machine, and both ends of the upper cover die and the lower cover die are connected to a loading and unloading machine.

[0010] The process of embossing the upper cover plate uses an independent first set of dies. The processes of blanking and punching the upper cover plate and blanking the lower cover plate are combined into an integrated die with one die cavity for two parts. The second set of dies for blanking and punching the upper cover plate and blanking the lower cover plate are arranged adjacent to the rear side of the first set of dies. The processes of folding the Z-shaped bend of the upper cover plate and a section of bending of the lower cover plate are combined into an integrated die with one die cavity for two parts. The third set of dies for folding the Z-shaped bend of the upper cover plate and a section of bending of the lower cover plate are arranged adjacent to the rear side of the second set of dies. The processes of flanging and bending the upper cover plate and the second section of bending of the lower cover plate are combined into an integrated die with one die cavity for two parts. The fourth set of dies for flanging and bending the upper cover plate and the second section of bending of the lower cover plate are arranged adjacent to the rear side of the third set of dies. The process of folding the V-shaped bend in the stamping process of the upper cover plate uses an independent fifth set of dies. The fifth set of dies for folding the V-shaped bend of the upper cover plate is arranged behind the fourth set of dies. The fifth set of dies and the sixth set of dies are flush with each other. The processes of the third section of bending and the fourth section of bending of the lower cover plate use an integrated die for multi-section stamping. The sixth set of dies for the third section of bending and the fourth section of bending of the lower cover plate are arranged adjacent to the rear side of the fourth set of dies. The sixth set of dies and the fifth set of dies are flush with each other. The processes of punching the upper cover plate and punching the lower cover plate are combined into an integrated die with one die cavity for two parts. The seventh set of dies for punching the upper cover plate and punching the lower cover plate are arranged adjacent to the rear side of the sixth set of dies. The processes of riveting the upper cover plate and riveting the lower cover plate are combined into an integrated die with one die cavity for two parts. The eighth set of dies for riveting the upper cover plate and riveting the lower cover plate are arranged adjacent to the rear side of the seventh set of dies. The upper and lower cover plate dies are optimized and combined. The 2nd, 3rd, and 4th processes of the upper cover plate are combined with the 1st, 2nd, and 3rd processes of the lower cover plate. The die changes from one die cavity for one part to one die cavity for two parts, and two products are punched out simultaneously. The number of dies is optimized from 6 sets to 3 sets.

[0011] Similarly, the 6th and 7th processes of the upper cover plate are combined with the 6th and 7th processes of the lower cover plate. The die changes from one die cavity for one part to one die cavity for two parts, and two products are punched out simultaneously. The number of dies is optimized from 4 sets to 2 sets.

[0012] Beneficial effects:

[0013] The upper and lower cover plate dies are optimized and combined. The 2nd, 3rd, and 4th processes of the upper cover plate are combined with the 1st, 2nd, and 3rd processes of the lower cover plate. The die changes from one die cavity for one part to one die cavity for two parts, and two products are punched out simultaneously. The number of dies is optimized from 6 sets to 3 sets.

[0014] Similarly, the 6th and 7th processes of the upper cover plate are combined with the 6th and 7th processes of the lower cover plate. The die changes from one die cavity for one part to one die cavity for two parts, and two products are punched out simultaneously. The number of dies is optimized from 4 sets to 2 sets.

[0015] Those that cannot be optimized and combined use separate dies.

[0016] In this way, a total of 8 sets of molds are required for the upper and lower cover plates, which can significantly reduce the costs of mold development, labor allocation, machine tools, etc. for product production. Description of the Drawings
