Description

Technical Field

[0001] This utility model relates to the field of sheet metal parts, specifically a high-strength sheet metal part. Background Technology

[0002] Sheet metal parts are made from thin metal sheets through sheet metal processing. If the sheet metal part is large, the strength of the sheet metal part made from thin metal sheets is insufficient, and the sheet metal part will bend significantly when subjected to pressure. If the strength is increased by increasing the thickness of the sheet metal part, the production cost will increase and the weight of the sheet metal part will also increase accordingly. Utility Model Content

[0003] The purpose of this utility model is to provide a high-strength sheet metal part to overcome the above-mentioned defects in the prior art.

[0004] According to the present invention, a high-strength sheet metal part includes a double-layer structure formed by two sheet metal bodies. The edges of the two sheet metal bodies are folded inward along their length direction to form a connecting edge. A reinforcing layer is provided between the two sheet metal bodies. The reinforcing layer consists of a wave-shaped support plate and a number of equally spaced reinforcing ribs. The number of reinforcing ribs are divided into upper and lower layers. The upper layer of reinforcing ribs penetrates the crest of the support plate, and the lower layer of reinforcing ribs penetrates the trough of the support plate.

[0005] Through the above technical solution, the reinforcing layer is set between the two sheet metal bodies. The wave-shaped support plate improves the compressive strength of the sheet metal parts. The crests and troughs of the support plate improve the bending strength of the sheet metal parts in the direction parallel to the crests and troughs. The reinforcing ribs improve the bending strength of the sheet metal parts in the direction parallel to the crests and troughs, thus increasing the overall strength of the sheet metal parts.

[0006] Furthermore, the support plate and the crests or troughs of the reinforcing ribs form a grid, each grid being rectangular, and the support plate and the upper or lower reinforcing ribs of half a cycle form an isosceles triangle.

[0007] Through the above technical solution, the multiple triangles formed between the support plate and the reinforcing ribs increase the compressive strength of the sheet metal parts by utilizing the stability of the triangles.

[0008] Furthermore, the support plate and the reinforcing rib are integrally formed from metal.

[0009] The above technical solution ensures the connection strength between the support plate and the reinforcing rib.

[0010] Furthermore, the starting and ending ends of the wavy support plate abut against the connecting edges on both sides, respectively.

[0011] The above technical solution facilitates the quick installation of the support plate between two sheet metal bodies by having both ends of the support plate abut against the connecting edge, and reduces the welding process, thus accelerating production efficiency.

[0012] Furthermore, the connecting edges of the two sheet metal bodies are detachably connected by a connecting block.

[0013] The above technical solution facilitates the disassembly and assembly of the reinforcing layer through the detachable connection between the two sheet metal bodies, and also allows for quick replacement of the sheet metal body or reinforcing layer when it is damaged.

[0014] Furthermore, grooves are provided on both the inner and outer sides of the connecting edge near one end of the connecting block. The connecting block is composed of a horizontal part in the middle and vertical parts on both sides forming an "H" shape. Each vertical part of the connecting block is fixed with an inwardly protruding strip, which can be inserted into the groove on the connecting edge.

[0015] Using the above technical solution, the long strip on the connecting block can be inserted into the groove, allowing for quick connection between two sheet metal bodies.

[0016] Furthermore, a screw rod is fixed inside the connecting block and passes through the connecting block. Clamping plates are provided at both ends of the connecting block. Through holes are opened in the clamping plates. The two ends of the screw rod pass through the through holes in the clamping plates at both ends of the connecting block. Nuts are threaded into both ends of the screw rod. The nuts and the connecting block can clamp the clamping plates.

[0017] With the above technical solution, the two nuts clamp the clamping plate to both ends of the connecting block, which can prevent the sheet metal body from slipping out of the connecting block and ensure the connection strength between the two sheet metal bodies.

[0018] The beneficial effects of this utility model are: the reinforcing layer is set between two sheet metal bodies, the wavy support plate improves the compressive strength of the sheet metal parts, the crests and troughs of the support plate improve the bending strength of the sheet metal parts in the direction parallel to the crests and troughs, and the reinforcing ribs improve the bending strength of the sheet metal parts in the direction parallel to the crests and troughs, thus increasing the overall strength of the sheet metal parts.

[0029] One embodiment of this utility model:

[0030] Reference Figures 1-6This utility model provides a high-strength sheet metal part, including a double-layer structure composed of two sheet metal bodies 10 made of sheet metal. The edges of the two sheet metal bodies 10 are folded inward along their length direction to form connecting edges 11. A reinforcing layer is provided between the two sheet metal bodies 10. The reinforcing layer consists of a wave-shaped support plate 20 and several equidistant reinforcing ribs 21. The reinforcing ribs 21 are divided into upper and lower layers. The upper reinforcing ribs 21 penetrate the crests of the support plate 20, and the lower reinforcing ribs 21 penetrate the troughs of the support plate 20. The crests and troughs of the support plate 20 are flat on the side closest to the adjacent sheet metal body 10 to facilitate contact between them. The crests or troughs of the support plate 20 and the reinforcing ribs 21 form a grid, and each grid is rectangular. Half a cycle of the support plate 20 and the upper or lower reinforcing ribs 21 form an isosceles triangle. The support plate 20 and the reinforcing ribs 21 are integrally formed from metal. The starting and ending ends of the wave-shaped support plate 20 abut against the connecting edges 11 on both sides, respectively.

[0031] Reference Figure 2 , Figure 5 The two sheet metal bodies 10 are detachably connected by a connecting block 30 through the connecting edge 11. The inner and outer sides of the connecting edge 11 near the connecting block 30 are provided with grooves. The connecting block 30 is formed by the horizontal part in the middle and the vertical parts on both sides in an "H" shape. The vertical part of the connecting block 30 is fixed with an inwardly protruding strip. The strip on the connecting block 30 can be inserted into the groove on the connecting edge 11. A screw 33 is fixed inside the connecting block 30 and passes through the connecting block 30. Both ends of the connecting block 30 are provided with clamping plates 31. The clamping plates 31 are provided with through holes. The two ends of the screw 33 pass through the through holes in the clamping plates 31 at both ends of the connecting block 30. Both ends of the screw 33 are threaded with nuts 32. The nuts 32 and the connecting block 30 can clamp the clamping plates 31.

[0032] When assembling sheet metal parts, align the two sheet metal bodies 10 and place the reinforcing layer between the two sheet metal bodies 10. The left and right ends of the support plate 20 abut against the connecting edges 11 on the left and right sides respectively. Then, insert the protruding strip on the connecting block 30 into the groove of the connecting edge 11 to connect the upper and lower connecting edges 11. Finally, put the clamping plates 31 on both ends of the screw 33 respectively and tighten the nuts 32 to fix the clamping plates 31 on the front and rear ends of the connecting block 30, thereby realizing the assembly of sheet metal parts.
