Various air conditioners Ventilation pipe construction And installation

The thickness of galvanized steel plate shall be selected in the processing workshop according to the list of materials used for the fabricated air duct, the galvanized steel plate shall be loaded into the leveling and reinforcing machine from the loading frame, and the machine shall be started to cut off the end of the steel plate. When loading, check whether the steel plate is inclined, try to cut a steel plate, and measure whether the cut line of the sheared steel plate is vertical to the edge line, and whether the diagonal line is consistent.

Input the cutting length and quantity in the material list into the computer, start the machine, and the computer will automatically cut and press the reinforcement. The sheet cutting must be rechecked to avoid mistakes.

ACL3100 plasma cutting machine is used for special shaped plates, and on-site electric shears are used for cutting sporadic materials. When using fixed dynamic shears, two hands should hold the steel plate, and the distance between the hands and the knife edge should not be less than 5cm. The force should be uniform and appropriate.
