Example Embodiment
[0125] The components of the thrust rod in the first embodiment are:
[0126] Element
[0127] The total length of casing 1 L 1 =810mm, the inner radius r of casing 1 1A =30mm; the maximum outer radius r of the bellows section of A ball head 2A 2A1 =30mm, the maximum outer radius of the bellows section of the V-shaped ball head 3 is 30mm; the radius of the arc section (2A6, 2B6) of the neck of the A ball head is The long radius of the elliptical segments (2A5, 2B5) is Oa=135mm, and the short radius is Ob=90mm.
[0128] The casing preparation process is hot extrusion molding, and the process is as follows:
[0129] In step 101, the aluminum alloy is prepared according to a certain ratio, and the aluminum alloy blank is heated to 460°C in a box-type resistance furnace for 60 minutes;
[0130] In step 102, the temperature of the extrusion die is heated to 500°C and kept for 30 minutes, and the billet is hot-extruded into Bar blanks;
[0131] In step 103, the bar stock is processed int...
