AI Technical Summary
During the pressing process of sheet metal parts, traditional solar ribs are difficult to effectively prevent the wrinkle of sheet metal parts.
By setting up vertical ribs and a rib on the sheet metal plate body and making them penetrate, the stretching ribs can simultaneously contact materials and absorb materials at the intersection points when closed, avoiding wrinkles caused by the difference in height between the stretching ribs and the plane.
It effectively prevents wrinkles from occurring during the edge pressing process, and increases the stability of the connection between vertical ribs and one rib.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sheet metal parts, in particular to a sheet metal part sun rib. Background Art
[0002] At present, the two ends of the headlamps of the inner and outer panels of the engine hood in the body sheet metal parts, or some special shapes after splicing of the framed outer door panels are usually arc-shaped. Therefore, when using square materials for drawing forming, since the two blanks at the corners are far from the parting line, it is necessary to ensure no wrinkling when the upper die and the blank holding surface are closed. However, optimizing the closing coloring of the blank holding surface requires controlling the shape of the draw bead, the blank holding force, the shape of the blank holding surface, etc. Among them, for such parts with a relatively simple blank holding surface shape of special-shaped parts, the optimization direction of the draw bead is the top priority of quality control. For such parts, we usually use sun ribs to control the closing wrinkling, but the traditional sun ribs have forming defects, and wrinkling still occurs during draw closing. Summary of the Invention
[0003] The purpose of the utility model is to provide a sheet metal part sun rib that prevents wrinkling when the blank holding ring of the sheet metal part. The utility model passes through the vertical rib and a rib to be penetrated, and when closing, the draw bead can touch the material at the same time, and suck the material at the intersection point, avoiding wrinkling caused by the height difference formed by the draw bead and the plane.
[0004] To achieve the above purpose, the technical solution adopted by the utility model to solve its technical problems is: a sheet metal part sun rib, including a rib arranged on the sheet metal part plate body, a vertical rib is arranged on the sheet metal part body, and the vertical rib is connected with the rib.
[0005] A through hole is arranged on the sheet metal part body, the rib is arranged on the periphery of the through hole, and the vertical rib is arranged at the corner of the sheet metal part body.
[0006] The vertical rib and the rib are perpendicular to each other.
[0007] A fillet is arranged at the connection of the vertical rib and the rib.
[0008] The vertical ribs are equally spaced.
[0009] The distance between adjacent vertical ribs is less than 120 mm, and the distance between adjacent vertical ribs is greater than 80 mm.
[0010] The height of the vertical rib is greater than 4 mm and less than 5 mm.
[0011] The radius of the fillet at the connection of the vertical rib and the rib is greater than 15 mm and less than 20 mm.
[0012] The beneficial effect of the utility model is:
[0013] When the sheet metal part plate body is drawn and closed, since the first rib and the vertical rib penetrate each other, the draw bead can touch the material simultaneously during closing and suck the material at the intersection, avoiding wrinkling caused by the height difference between the draw bead and the plane; a fillet is provided at the connection between the vertical rib and the first rib to prevent stress concentration, thereby increasing the stability of the connection between the vertical rib and the first rib.

[0017] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0018] The following describes in detail the specific implementation of the present utility model in conjunction with specific embodiments.
[0019] As Figure 1-2 shown, the sun rib of the sheet metal part includes a first rib 3 provided on the sheet metal part plate body 1, and a vertical rib 4 is provided on the sheet metal part body 1. The vertical rib 4 penetrates the first rib 3. Specifically, the vertical rib 4 and the first rib 3 on the sheet metal part body 1 are provided on the same side, and a groove at the same position as the rib is provided on the other side of the sheet metal part plate body 1.
[0020] When the sheet metal part plate body 1 is drawn and closed, since the first rib 3 and the vertical rib 4 penetrate each other, the draw bead can touch the material simultaneously during closing and suck the material at the intersection, avoiding wrinkling caused by the height difference between the draw bead and the plane.
[0021] Specifically, referring to Figure 1 , a through hole 2 is provided on the sheet metal part 1 body, the first rib 3 is provided on the periphery of the through hole 2, and the vertical rib 4 is provided at the corner of the sheet metal part body 1. The strength of the through hole 2 is strengthened by the first rib 3, and the strength of the corner of the sheet metal part body 1 is strengthened by the vertical rib 4.
[0022] The vertical rib 4 is perpendicular to the first rib 3 to facilitate the stable connection between the vertical rib 4 and the first rib 3 after stretching.
[0023] A fillet is provided at the connection of the vertical rib 4 and the first rib 3 to prevent stress concentration, thereby increasing the stability of the connection between the vertical rib 4 and the first rib 3.
[0024] The vertical ribs 4 are evenly distributed, so as to ensure that the vertical ribs 4 are not prone to wrinkling during stretching. In this embodiment, three vertical ribs 4 are provided.
[0025] The distance between adjacent vertical ribs 4 is less than 120 mm and greater than 80 mm, so as to ensure that the vertical ribs 4 can stably perform the strengthening work. In this embodiment, the distance between adjacent vertical ribs 4 is 90 mm.
[0026] The height of the vertical rib 4 is greater than 4 mm and less than 5 mm, so as to ensure that the vertical rib 4 can stably strengthen the sheet metal part body 1. In this embodiment, the height of the vertical rib 4 is 4.5 mm.
[0027] The radius of the fillet at the connection of the vertical rib 4 and the first rib 3 is greater than 15 mm and less than 20 mm, so as to ensure the connection strength between the vertical rib 4 and the first rib 3. In this embodiment, the radius of the fillet is 18 mm.
[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
