[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a stamping and welding assembly for the right front corner of an automobile. According to the shape and structure of the workpiece, the workpiece is divided into three parts, which are stamped separately, and then positioned using planes and holes, and then welded together.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a right front corner die-stamped welding assembly for automobiles, including a main body, a secondary body that fits with the outer side of the top end of the main body and the inner side of the bottom end of the main body, and a Z-shaped connector connecting the main body and the secondary body; the top two ends of the main body are provided with horizontal folded edges, which are respectively positioning plane one and positioning plane two, positioning plane one is provided with positioning hole one, positioning plane two is provided with positioning hole two, the secondary body has an L-shaped cross section, the bottom of the secondary body is provided with positioning plane three, the middle of positioning plane three is an arc-shaped notch, positioning plane three is provided with positioning hole three and positioning hole four at both ends of the arc-shaped notch, the lower surface of the Z-shaped upper fold of the connector fits with the upper surface of positioning plane two, and is provided with positioning hole five that mates with positioning hole two, the upper surface of the Z-shaped lower fold of the connector fits with the lower surface of positioning plane three, and is provided with positioning hole six that mates with positioning hole four.

[0005] Preferably, the diameter of the fifth positioning hole is equal to that of the second positioning hole.

[0006] Preferably, the positioning hole six is ​​an elongated hole with a width equal to the diameter of the positioning hole four.

[0007] Preferably, the upper folded edge of the connector is also provided with a positioning hole.

[0008] The beneficial effects of this utility model are: a stamped and welded assembly for the right front corner of an automobile, comprising a main body, a secondary body whose top outer side is fitted with the bottom inner side of the main body, and a Z-shaped connector connecting the main body and the secondary body. Each stamped component is positioned by interlocking locating surfaces and locating holes, and then welded together to form a stamped and welded structure, thereby reducing the difficulty of stamping and ensuring product quality and precision.

Detailed Implementation

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the present invention.

[0016] like Figures 1-4 As shown, this embodiment of a right front corner die-stamped welding assembly for automobiles includes a main body 1, a secondary body 2 whose top outer side is fitted to the bottom inner side of the main body 1, and a Z-shaped connector 3 connecting the main body 1 and the secondary body 2; the top two ends of the main body 1 are provided with horizontal folded edges, namely a positioning plane 11 and a positioning plane 12, respectively; the positioning plane 11 is provided with a positioning hole 13, and the positioning plane 12 is provided with a positioning hole 14; the secondary body 2 has an L-shaped cross-section, and the bottom of the secondary body 2... The connector 3 is provided with a positioning plane 3 21, which has an arc-shaped notch in the middle. Positioning holes 3 22 and 4 23 are provided at both ends of the arc-shaped notch. The lower surface of the Z-shaped upper fold of the connector 3 is attached to the upper surface of the positioning plane 2 12 and has a positioning hole 5 31 that mates with the positioning hole 2 14. The upper surface of the Z-shaped lower fold of the connector 3 is attached to the lower surface of the positioning plane 3 21 and has a positioning hole 6 32 that mates with the positioning hole 4 23. Additionally, the upper fold of the connector 3 also has a positioning hole 7 33 to prevent the connector 3 from tilting.

[0017] According to the shape and structure of the product, combined with the deformation properties of the metal during stamping, the right front corner mold of the car in this embodiment divides the product into three parts for stamping, and sets positioning surfaces and positioning holes in each part. Then, the three parts are positioned and assembled together with positioning surfaces and positioning holes, and spot welded to fix them, and finally welded into shape.
