Detailed description of the invention
Fig. 1 to Fig. 5 has gone out a kind of welded type aluminium alloy box embodiment of the present invention, this aluminium alloy box comprises forward flange plate 1, top board 2, left plate 3, right plate 4, base plate 5 and backboard 6, forward flange plate 1 is provided with overlap joint concave station 7, top board 2, left plate 3, one end that right plate 4 and base plate 5 are connected with forward flange plate 1 is equipped with and the clinch 8 overlapping concave station 7 and coordinate, top board 2, left plate 3, one end that right plate 4 and base plate 5 are connected with backboard 6 is equipped with and overlaps boss 9, backboard 6 is installed with on overlap joint boss 9, each plate adjoiner is provided with the welding pool 10 of opening towards casing outside, each plate is welded to connect.Welded type aluminium alloy box of the present invention, adopt welding procedure, casing inner structure can complete in advance (calculating welding deformation amount), does not need postwelding to process, significantly reduces costs while greatly can shortening the process-cycle; Both ensured after welding that casing had certain intensity, also ensured good sealing requirements simultaneously.
In the present embodiment, left plate 3 and right plate 4 are divided into top board 2 and base plate 5 both sides, and offset with top board 2, base plate 5 both sides, and structure is simple, be convenient to clamping, thus improves welding quality.
The thickness of slab of forward flange plate 1, top board 2, left plate 3, right plate 4, base plate 5 and backboard 6 is 20mm ~ 25mm, and in the present embodiment, the thickness of slab of forward flange plate 1, top board 2, left plate 3, right plate 4, base plate 5 and backboard 6 is 23mm.
