[0002] Sheet metal parts are products processed through sheet metal technology and are widely used in fields such as electronic appliances, communication, automotive industry, medical devices, aerospace, etc. A semi - enclosed sheet metal part is a sheet metal part that is partially open and partially closed in terms of structure and shape, and is usually used for product components that require a certain strength but are not completely enclosed. The design and manufacture of such sheet metal parts have a certain degree of complexity, especially when they are used in industries such as aviation and automotive that require high precision and high strength.
[0003] Although the existing sheet metal parts have many benefits, there are still the following problems. They lack a strengthening structure for the bent edges or flanged edges, resulting in the stacked sheet metal parts squeezing each other after production, which can cause deformation at the bent parts, affecting the overall dimensions of the sheet metal parts and their quality.

[0010] By adopting the above technical solution, the limiting plate enters the inner wall of the receiving groove and is deformed by an external sheet metal device, so that after the limiting plate is deformed, it fills the inner wall of the receiving groove.
[0011] Specifically, fitting blocks are arranged on the outer walls on both sides of the limiting plate, and the fitting blocks are located inside the fitting grooves.
[0012] By adopting the above technical solution, after the limiting plate is deformed, the fitting blocks protrude, so that the fitting blocks enter the inside of the fitting grooves to fix the bent edges and maintain the connection strength between the bent edges and the sheet metal part body.
[0013] Specifically, a combination groove is formed on one side of the outer wall at the lower end of the reinforcing rib, and the inner wall of the combination groove is designed in a convex shape.
[0014] By adopting the above technical solution, the combination groove can receive the limiting posts, so as to cooperate with the reinforcing rib to limit the position of the outwardly turned bent edge and maintain the relative position stability between the outwardly turned bent edge and the sheet metal part body.
[0015] Specifically, a plug is arranged on the outer wall at the upper end of the limiting post, and the plug is located inside the combination groove, and the outer wall at the upper end of the plug is designed in a circular arc shape.
[0016] By adopting the above technical solution, after the limiting post enters the inside of the combination groove, it is continuously pushed and moved by an external sheet metal device and the outwardly turned bent edge, so that the limiting post fills the combination groove, thereby protruding the plug, and the plug is stuck into the inner wall of the combination groove to ensure the connection strength between the outwardly turned bent edge and the sheet metal part body.

[0027] In order to save manpower and improve efficiency, as an embodiment of the present utility model, as Figure 1 , Figure 2 , Figure 3 , Figure 4 shown, a sheet metal part with a semi-closed structure described in the present utility model includes a sheet metal part body 1, a receiving groove 5, a fitting groove 6 and a combination groove 9.

Limiting plates 7 are installed on both outer walls of the sheet metal part body 1. Reinforcing ribs 2 are installed on both outer walls of the sheet metal part body 1 in an equidistant and parallel distribution. Limiting posts 10 are installed on the upper outer wall of the outer bent edge 3 in an equidistant and parallel distribution.
[0028] During use, the fitting block 8 is inserted into the fitting groove 6 to fix the bent edge 4, keeping the bent edge 4 fixed outside the sheet metal part body 1. The limiting post 10 is inserted into the combination groove 9 to keep the bending position between the outer bent edge 3 and the sheet metal part body 1 stable.
[0029] In order to improve the visual inspection of the bending angle of the bent edge 4, exemplarily, as Figure 4 shown, a receiving groove 5 is provided inside the bent edge 4. Fitting grooves 6 are provided on both inner walls of the receiving groove 5. The receiving groove 5 adopts a through design.
[0030] During use, the storage groove 5 stores the limiting plate 7, and by observing the filling condition of the limiting plate 7 against the inner wall of the storage groove 5, the fitting tightness between the bent edge 4 and the sheet metal part body 1 can be visually known, and whether the bending position of the bent edge 4 meets the standard can be known.
[0031] To improve the connection strength of the bent edge 4, for example, as Figure 4 shown, the size of the limiting plate 7 is smaller than that of the storage groove 5, and the limiting plate 7 is located inside the storage groove 5.
[0032] During use, the limiting plate 7 enters the inner wall of the storage groove 5 and is extruded and deformed by an external sheet metal device, so that after the limiting plate 7 is deformed, it fills the inner wall of the storage groove 5.
[0033] To improve the connection strength of the bent edge 4, for example, as Figure 4 shown, fitting blocks 8 are provided on both outer walls of the limiting plate 7, and the fitting blocks 8 are located inside the fitting grooves 6.
[0034] During use, after the limiting plate 7 is deformed, the fitting blocks 8 protrude, so that the fitting blocks 8 enter the inside of the fitting grooves 6 to fix the bent edge 4 and maintain the connection strength between the bent edge 4 and the sheet metal part body 1.
[0035] To maintain the position of the outwardly turned bent edge 3, for example, as Figure 2 shown, a combination groove 9 is formed on one side of the outer wall at the lower end of the reinforcing rib 2, and the inner wall of the combination groove 9 is designed in a convex shape.
[0036] During use, the combination groove 9 can store the limiting post 10, so as to cooperate with the reinforcing rib 2 to limit the position of the outwardly turned bent edge 3 and maintain the relative position stability between the outwardly turned bent edge 3 and the sheet metal part body 1.
[0037] To strengthen the connection strength of the outwardly turned bent edge 3, for example, as Figure 2 shown, a plug 11 is provided on the outer wall at the upper end of the limiting post 10, and the plug 11 is located inside the combination groove 9, and the outer wall at the upper end of the plug 11 is designed in a circular arc shape.

[0039] When the present utility model is in use, when the bent edge 4 is bent and processed by an external sheet metal device, the limiting plate 7 enters the inside of the receiving groove 5, and the limiting plate 7 is deformed by the extrusion of the sheet metal device, thereby extruding the inner wall of the receiving groove 5. By observing the shape of the limiting plate 7 inside the receiving groove 5, the staff can know the tightness of the fit between the bent edge 4 and the sheet metal part body 1;
[0040] After the limiting plate 7 is extruded and deformed, the protruding fitting block 8 will protrude, and the fitting block 8 can enter the inside of the fitting groove 6 to improve the connection strength between the bent edge 4 and the sheet metal part body 1.
[0041] When the outward bent edge 3 is bent and processed by an external sheet metal device, the outward bent edge 3 drives the limiting column 10 to enter the inside of the combined groove 9. The upper end of the limiting column 10 is deformed by the extrusion of the inner wall of the combined groove 9, so as to fill the combined groove 9;
[0042] And after the limiting column 10 is extruded, the plug 11 protrudes, so that the plug 11 exists on the inner wall of the combined groove 9, so that the reinforcing rib 2 is connected to the outward bent edge 3, and the bending shape between the outward bent edge 3 and the sheet metal part body 1 can be controlled.
