Embodiment Construction
[0041] A method for forming a hollow member, the technical solution of which is to include the following steps:
[0042] Step 1: Die preparation, first design the lower die 2, the upper die 5, the left punch 4 and the right punch 7 according to the needs of the shape of the components. The lower die 2 is connected to the lower table 1 of the press, the upper die 5 is connected to the upper slider 6 of the press, and a check valve 17 is installed between the left punch 4 and the high pressure source 16;
[0043] Step 2: Set up anti-deformation mechanism A (9), anti-deformation mechanism B (11), anti-deformation mechanism C (13), and anti-deformation mechanism D (15) on the mold. One end of the anti-deformation mechanism faces the mold cavity, and one end extends. Out of the mold cavity, and connected with the ejector mechanism 8, 10, 12, 14 of the press. The main point is the width of the anti-deformation mechanism a 1 about 0.1 a ~0.3 a ,high b 1 about 0.1b ~0.3 b ,...
