It is mainly composed of expansion device, close device, gear and rack opening and closing device, skew device, workbench and electronic control system;

2. Working principle:

(1) Put the bent single piece of aluminum tube into the skew mold of the skew machine;

(2) Press the start button, the expansion cylinder will expand the single piece, the close cylinder will close the aluminum tube, the rack and pinion opening and closing cylinder will send the rack into the gear;

(3) The skew oil cylinder simultaneously twists the R arcs at both ends of the single piece to the opposite direction by 30° through the rack and pinion. When the twist is in place, the expansion oil cylinder is loosened and returned, and the skewed aluminum tube is taken out;

(4) Press the start button again, the whole action is reset, and the skew work is completed.

3. Equipment structure requirements (different from other manufacturers):

(1) Increase the skew head close-up device and the gear rack opening and closing device to make the process structure more reasonable.

(2) Increase the skew head circumferential positioning device to ensure the same skew angle.
