Embodiment Construction
[0047] Aiming at the deficiencies in the prior art, the present invention proposes a liquid-filled forming device and method for aluminum alloy differential thickness tailor welded blanks, which solves the problems that the conventional forming of aluminum alloy differential thickness tailor welded blanks is easy to break and the weld seam moves greatly. The invention relates to a liquid-filled forming device and method for an aluminum alloy tailor-welded blank of differential thickness, which relates to a tailor-welded blank of differential thickness, which refers to a tailor-welded blank of non-equal thickness. The schematic diagram of its main parameters is as follows figure 2 As shown, the thickness of the thin plate of the tailor-welded blank is t b , the thickness of the thick plate is t h , the diameter of the tailor-welded blank is D, and the chord height of the thick plate is D h , the chord height of the thin plate is D b , the thickness difference between the thi...

The invention relates to an aluminum alloy difference thickness welding plate liquid filling forming method. Firstly, a difference thickness welding plate is processed, a left concave mold sleeve anda right concave mold sleeve are combined to be placed into a concave mold seat, the concave mold seat is fixed on a lower working platform of a hydraulic machine, an independent hydraulic system source and the concave mold seat are connected, then a right radial pressure chamber heel block and a left radial pressure chamber heel block are mounted on the concave mold seat, and the independent hydraulic system source is connected with the left and right radial pressure chamber heel blocks. The difference thickness welding plate is placed on the left and right radial pressure chamber heel blocks,and an edge pressing ring is placed on the left and right radial pressure chamber heel blocks and is connected with a hydraulic cylinder of the hydraulic machine. Finally a convex mold is connected to a main cylinder of the hydraulic machine, the main cylinder controls the convex mold to move downwards, an edge pressing cylinder controls the edge pressing ring to move downwards, a liquid medium is filled into a high pressure liquid filling chamber through the independent hydraulic system source, the liquid chamber pressure is established and changed, and difference thickness welding plate parts are drawn and formed.
Description
technical field [0001] The invention relates to the technical field of special forming technology for light alloy tailor welded blanks, in particular to a liquid-filled forming method for aluminum alloy tailor welded blanks with differential thickness. Background technique [0002] With the further development of science and technology and the continuous progress of society, lightweight structure plays an increasingly important role in improving resource utilization, reducing energy consumption and improving the performance of parts, and has become one of the development trends of today's manufacturing industry. , and there are mainly two ways to achieve lightweight structure: material and structure: the material way refers to replacing heavy materials such as steel with lightweight materials such as aluminum alloys, magnesium alloys, and titanium alloys, while aluminum alloys have low density and strong corrosion resistance. , high specific strength and specific stiffness, ...
