Embodiment 1

[0013] Due to the small deformation of magnesium alloy at room temperature, the deformation of AZ80 at room temperature is greater than 11%, even at 100 degrees Celsius, it is only 20%, which makes it easy to crack when extruding magnesium alloy at room temperature, making it difficult to use general The method measures the deformation of magnesium alloy at room temperature. This embodiment can accurately measure the small deformation of magnesium alloy, which has practical significance.

[0014] Such as figure 1 Shown: Install the upper fastening device on the hydraulic press, use the hydraulic press to lift the upper template connected with the upper fastening device, so that the punch and die are separated, take a cylindrical blank made of AZ80 magnesium alloy, and measure the outer surface of the blank path ,the inside diameter of ,high , Put the blank into the die, put the steel ball in the center hole of the blank, push the upper template through the hydraulic pres...

Embodiment 2

[0016] This embodiment is used to measure the allowable deformation degree of magnesium alloy inner hole cold shaping, such as figure 1 As shown, install the upper fastening device on the hydraulic press, use the hydraulic press to lift the upper template connected with the upper fastening device, so that the punch and the die are separated, take the cylindrical blank made of magnesium alloy, put the blank into the concave Die, put the steel ball in the center hole of the billet, push the upper template through the hydraulic press to squeeze the steel ball downward through the punch, the pressure applied is transmitted to the billet through the steel ball, causing the metal of the billet to flow along the wall of the billet, and the steel ball Penetrate the billet and complete the pressurization; the hydraulic machine lifts the upper platen to drive the punch to move upwards until the distance between the punch and the die is greater than the height of the billet after extrusio...
