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.
