[0038] In the related art, the sheet metal splicing and welding process is to mutually adhere the edges of two plate structure sheet metal parts and then weld by using a welding device, at this time, due to uneven heat input and cooling in the welding process, the two spliced sheet metal parts are prone to deformation; in addition, if the edges of the two sheet metal parts are uneven or the edges are not completely adhered, a situation of too large welding gap occurs, thereby affecting the overall appearance and stability of the sheet metal splicing and welding product.

[0039] In order to solve the above technical problems, the utility model provides a sheet metal splicing and welding structure.

[0040] Please refer to Figures 1-4 In an embodiment of the utility model, the sheet metal splicing and welding structure comprises:

[0041] The first sheet metal part 100 is provided with a first bending part 110 at the edge thereof;

[0042] The second sheet metal part 200 is provided with a second bending part 210 at the edge thereof, and the second bending part 210 is mutually adhered with the first bending part 110 to form an adhered part 300;

[0043] The first connecting piece 400 is covered on the adhered part 300, and the opposite sides of the first connecting piece 400 are respectively welded with the first sheet metal part 100 and the second sheet metal part 200;

[0044] The second connecting piece 500 is horizontally arranged on the first sheet metal part 100 and the second sheet metal part 200, and the horizontal sides of the second connecting piece 500 are respectively welded with the first sheet metal part 100 and the second sheet metal part 200.

[0045] The technical scheme of the utility model is to set the first bending part 110 and the second bending part 210 at the welding edges of the first sheet metal part 100 and the second sheet metal part 200 respectively, mutually adhere the first bending part 110 with the second bending part 210 to form the adhered part 300, then cover the first connecting piece 400 on the adhered part 300, and weld the opposite sides of the first connecting piece 400 with the first sheet metal part 100 and the second sheet metal part 200 respectively, meanwhile, horizontally arrange the second connecting piece 500 on the first sheet metal part 100 and the second sheet metal part 200, and weld the horizontal sides of the second connecting piece 500 with the first sheet metal part 100 and the second sheet metal part 200 respectively, in this way, under the double action of the first connecting piece 400 and the second connecting piece 500, the first sheet metal part 100 and the second sheet metal part 200 can be effectively connected.

[0046] Differing from the two metal sheets in the background art being welded by the edges being mutually attached, in the metal sheet splicing and welding structure of the present application, the first bending part 110 and the second bending part 210 are used to be attached and contacted, which can make the first metal sheet 100 and the second metal sheet 200 be better attached and connected, and the connection part can also be ensured to be flat, so there is no need to worry about the case that the welding edge is not flat or the welding edge is not completely attached, which leads to the welding gap being too large; at the same time, since the first metal sheet 100 and the second metal sheet 200 are indirectly connected by the first connecting part 400 and the second connecting part 500, and the welding part is located in the middle area of the first metal sheet 100 and the second metal sheet 200, it can be understood that the middle area of the metal sheet has higher hardness than the edge, so it is difficult to deform; therefore, there is no need to worry about the deformation of the metal sheet caused by uneven heat input and cooling during welding; thus, the purpose of effectively improving the overall appearance and stability of the metal sheet splicing and welding product is achieved.

[0047] Specifically, the first metal sheet 100 and the first bending part 110 are arranged at a right angle; and / or, the second metal sheet 200 and the second bending part 210 are arranged at a right angle. By setting the bending angle of the first bending part 110 and the second bending part 210, the flatness of the splicing and welding product is limited. In the present embodiment, the first bending part 110 and the second bending part 210 are both arranged at a right angle, so that the first metal sheet 100 and the second metal sheet 200 after splicing and welding are on the same plane to form an overall flat plate structure.

[0048] Further, the first connecting part 400 adopts a U-shaped structure, the U-shaped middle part of the first connecting part 400 is used to cover the attachment part 300, and the two U-shaped open ends of the first connecting part 400 are welded with the first metal sheet 100 and the second metal sheet 200 respectively. By such arrangement, even if the free end edges of the first bending part 110 and the second bending part 210 are not flat, the U-shaped middle part of the first connecting part 400 can cover and shield them to avoid exposure, thereby further improving the overall appearance of the splicing and welding product.

[0049] Further, the height of the U-shaped middle part of the first connecting part 400 is greater than the height of the attachment part 300. By such arrangement, it is ensured that the U-shaped middle part of the first connecting part 400 can effectively accommodate the attachment part 300, so as to avoid the attachment part 300 being supported by the first connecting part 400 due to the height being too high, thereby causing the two U-shaped open ends of the first connecting part 400 to be unable to be effectively welded with the first metal sheet 100 and the second metal sheet 200.

[0050] Further, the second connecting piece 500 adopts a U-shaped structure; in this way, the first connecting piece 400 and the second connecting piece 500 are both arranged as U-shaped structures, so that the first connecting piece 400 and the second connecting piece 500 can be produced by the same production process, which is beneficial to save the production process.

[0051] Further, the height of the U-shaped middle part of the second connecting piece 500 is equal to the height of the U-shaped middle part of the first connecting piece 400; in this way, the connection between the first connecting piece 400 and the second connecting piece 500 of the spliced product will not be uneven.

[0052] Further, the length direction of the second connecting piece 500 is arranged at a right angle with the length direction of the first connecting piece 400; in this way, the spliced product is connected by the first connecting piece 400 and the second connecting piece 500 intersecting longitudinally and transversely, which effectively improves the bending strength and the connection strength between the first sheet metal piece 100 and the second sheet metal piece 200.

[0053] Specifically, the first connecting piece 400 is provided with a first clearance groove 310 on the side facing the second connecting piece 500, and the second connecting piece 500 is provided with a second clearance groove 510 on the side facing the first connecting piece 400, and the first clearance groove 310 and the second clearance groove 510 are concave-convex matched; in this way, the first clearance groove 310 and the second clearance groove 510 are concave-convex matched to prevent the connection between the first connecting piece 400 and the second connecting piece 500 from interfering, so that the second connecting piece 500 cannot be effectively connected to the first sheet metal piece 100 and the second sheet metal piece 200 at the same time.

[0054] Specifically, the first connecting piece 400 is arranged in a multi-section structure along the length direction, and the second connecting piece 500 is arranged between two adjacent first connecting pieces 400; in this way, the first connecting piece 400 is arranged in a multi-section structure to prevent the connection between the first connecting piece 400 and the second connecting piece 500 from interfering, so that the first connecting piece 400 and the second connecting piece 500 cannot be effectively connected to the first sheet metal piece 100 and the second sheet metal piece 200 at the same time.

[0055] As a preferred scheme of the above embodiment, the edge of the first sheet metal piece 100 is provided with a third bending part 120, and the third bending part 120 is arranged adjacent to the first bending part 110; the edge of the second sheet metal piece 200 is provided with a fourth bending part 220, and the fourth bending part 220 is arranged adjacent to the second bending part 210; the side edge of the third bending part 120 and the side edge of the fourth bending part 220 are mutually attached and welded. In this way, since the third bending part 120 and the fourth bending part 220 respectively belong to a part of the first sheet metal piece 100 and the second sheet metal piece 200, by welding the third bending part 120 and the fourth bending part 220, a direct connection between the first sheet metal piece 100 and the second sheet metal piece 200 is formed, thereby further improving the connection strength between the first sheet metal piece 100 and the second sheet metal piece 200. It can be understood that, since the third bending part 120 and the fourth bending part 220 are located at the inner side edge position of the tailor-welded product, the overall appearance of the tailor-welded product does not require the inner side edge position, because the inner side edge position of the tailor-welded product cannot be seen from the outside. In this way, the third bending part 120 and the fourth bending part 220 can be directly welded without affecting the overall appearance of the tailor-welded product.

[0056] Specifically, the welding mode between the first connecting piece 400 and the first sheet metal piece 100 and the second sheet metal piece 200 (i.e., the A region of the attached Figure 3 drawing), and / or the welding mode between the second connecting piece 500 and the first sheet metal piece 100 and the second sheet metal piece 200 (i.e., the B region of the attached Figure 2 drawing), and / or the welding mode between the third bending part 120 and the fourth bending part 220 (i.e., the C region of the attached Figure 1 drawing) adopts any one of electric arc welding, argon arc welding or laser welding. In this way, electric arc welding is a method of using an electric arc as a heat source for welding; argon arc welding uses argon as a protective gas to prevent oxidation in the welding area, and is suitable for high-quality welding requirements; laser welding uses a high-energy-density laser beam as a heat source for efficient and precise welding, and is suitable for welding of micro parts and parts with poor accessibility. In actual operation, the operator can select a suitable welding mode to weld the first connecting piece 400 / second connecting piece 500 and the first sheet metal piece 100 and the second sheet metal piece 200, and / or to weld the third bending part 120 and the fourth bending part 220 according to the actual situation on site, and the present application does not make specific limitations.

[0057] It should be noted that other contents of the sheet metal tailor-welding structure disclosed in the present application are prior art, and will not be described here.

[0058] The above is only optional embodiment of the present application, and does not limit the patent scope of the present application, and any direct / indirect application of the present application in other related technical fields is included in the patent protection scope of the present application.
