Second, the working principle:
Will be fused cast Cu company long aluminum rods in the loading frame first, by rolling stick front into a long stick from of a root into the rod to the reheating furnace heating. In the process of the heating bar will flip, mobile. Each bar heating duration of no less than 2 hours later, in transmission rod mechanism driven by long rods are gradually into heat within the shear scale, and the fixed knife in the bar, under the influence of shear cylinder, promote activity c2: under the knife cut the bar, and then by the top rod oil cylinder to set a fixed knife bar outside.
