The sectional type sheet metal part reinforced processing technology has the advantages that the branch side plates which enclose the side frames are in an overlapped state, so that the thickness of the side frames is enhanced; the overlapped branch side plates are embedded into the bulges through the through holes, the pressing bulges are pressed through the pressing equipment and are attached into the outward-expanded groove, and the two-two connection and fixation of the sectional side plates are realized on the premise of no need of bolts; the breach is used for placing the side frame, and the side frame is then overlapped in the short hem outside of turning over, and wherein, the short hem of turning over and breach provide the support for the side frame, breach and side frame welded fastening, the side frame still with long hem, the short hem welded fastening of turning over simultaneously, improved the joint strength of side frame and bottom plate, to sum up, this application can improve the joint strength of sectional type sheet metal component for the box that the sheet metal component constitutes is difficult for warping.

As a further improvement of the invention, a dislocation preventing structure is arranged between the overlapped branch side plates. Be used for preventing at the protruding in-process of pressfitting, take place to slide between two liang of branch curb plates, influence the shaping quality of sheet metal component then.

Preferably, the anti-dislocation structure is a first wave groove structure and a second wave groove structure which are integrally formed on the inner side walls of the overlapped branch side plates, and the first wave groove structure is meshed with the second wave groove structure.

Preferably, the first wave groove structure part is in X-axis trend, and the other part is in Y-axis trend, and the second wave groove structure and the first wave groove structure are matched and meshed with each other. The X axis and the Y axis of the plane are limited, so that the situation that sliding is not easy to occur between every two branch side plates is guaranteed.

Preferably, the bottom plate is provided with a reinforcing rib, the reinforcing rib is positioned between the two long turned edges and is parallel to the short turned edges, and the reinforcing rib is equal to the short turned edges in length. The side frames are further supported, and the connection strength of the sheet metal part is further enhanced.

Preferably, the side frame and the short flanging edge are fixed through bolts. Besides the welding fixation, in order to further enhance the connection strength of the side frame and the bottom plate, the side frame and the bottom plate can be fixed by matching with bolts.
