Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1-12, the invention provides a structure for buckling, welding and limiting a sheet metal part.
Specifically, sheet metal component lock welding limit structure sets up on the sheet metal component, and the sheet metal component includes
Sheet metal part 1; sheet metal component two 2, sheet metal component lock welding limit structure includes a plurality of protruding platforms that form at sheet metal component two 2's lateral wall, and sheet metal component two 2 can peg graft fixedly each other with sheet metal component one 1 and constitute the product piece, is formed with cavity 3 in the product piece, and when sheet metal component two 2 peg graft each other with sheet metal component one 1, all protruding platforms all hold up sheet metal component one 1 in order to make cavity 3's height keep setting for the distance.
According to the invention, the positions of the sheet metal part II 2 and the sheet metal part I1 can be limited through the arrangement of the protruding platforms, and specifically, when the sheet metal part II 2 and the sheet metal part I1 are mutually inserted, all the protruding platforms support the sheet metal part I1 so as to keep the height of the cavity 3 at a set distance.
The setting of the set distance in the invention can be set according to actual requirements.
Because the sheet metal part 1 and the sheet metal part 2 need to be bent before being spliced, so that a product part after subsequent splicing is in a required shape, but when the sheet metal part 1 and the sheet metal part 2 are bent to a certain radian, the situation that materials are piled up (namely, wrinkling phenomenon) is easy to occur, the protruding table is further limited, a plurality of cambered surfaces 4 are arranged at the edge of the product part, and the protruding table is arranged in the area where the cambered surfaces 4 are located. The provision of the raised table avoids wrinkling, i.e. spreading out the accumulated material by the raised table to reduce stamping defects.
Because sheet metal component two 2 can peg graft with sheet metal component one 1 each other, but only peg graft and can only make sheet metal component two 2 and sheet metal component one 1's position preliminary fixed, in order to make the product see can normal use, so, sheet metal component two 2 can peg graft each other with sheet metal component one 1 and fix through the welding mode in sheet metal component two 2 and sheet metal component one 1's overlap joint department, protruding platform can form the interval welding point when sheet metal component two 2 and sheet metal component one 1 welding.
The position of the sheet metal part II 2 and the sheet metal part I1 can be fast fixed in a welding mode, but before welding, the sheet metal part II 2 is tightly attached to the sheet metal part I1, so that stress is easy to generate during welding, the product is easy to generate welding deformation, the formation of interval welding points is equivalent to breaking welding seams, the welding stress is released, and meanwhile, the material forming quality can be improved.
And the length of interval welding point is greater than protruding platform length, so the setting can ensure to release welding stress with higher efficiency under the condition that does not influence protruding platform, if the length of interval welding point is less than protruding platform length, then represents that the welding seam breaks the less welding stress release volume of department and does not necessarily satisfy the requirement, still makes protruding platform deformation easily in the welding process simultaneously.
Both ends of the cavity 3 are open, and the surface of the product piece is provided with an opening 5, and the opening 5 can guide an external support to enter the cavity 3.
The reason is that although the high position of cavity 3 has been restricted through protruding platform after sheet metal component two 2 and sheet metal component 1 pegged graft, but follow-up still need welded fastening, and if produce and rock in the welded fastening process just make between sheet metal component two 2 and the sheet metal component one 1 do not have protruding platform department and rock even relative slip easily, make the height of cavity 3 one side (specifically do not have protruding platform department) reduce at last, and set up opening 5, it can cooperate cavity 3 open-type both ends, the external support is put into of guide, external support can select the part with cavity 3 equiheight, make whole product piece receive the support of three point (namely the external support of cavity 3 open-type both ends and opening 5 department brings the holding power).
Because sheet metal part two 2 and sheet metal part one 1 need be applied in different regions, so the thickness of sheet metal part two 2 and sheet metal part one of selecting also is different, and the sheet metal part two 2 of different thickness is great with sheet metal part two 1 when overlap joint, and the phenomenon that it easily appears sliding away from protruding platform edge when contacting protruding platform, so to above-mentioned problem, for protruding platform provides following embodiment to face different circumstances (i.e. protruding platform embodiment that different cambered surface 4 set up is different, specifically should set up according to the demand).
Example one
When the sheet metal part two 2 and the sheet metal part one 1 which are required to face are thicker, if the welded seam is on the same line, the pressure at the welded seam is larger, then the welding seam position in the welding process can be changed or the product deformation is caused by larger stress after the welding is completed due to the fact that the pressure is matched with the welding stress of the whole product, and the following embodiment is provided:
