We call DH-DW16B Type Electric Pattern Bender as the universal equipment, inasmuch the newly developed machine has almost realized all the functions that the original manual operation benders have (except pretzel-pattern twist machine), and we can electrically realize the process by numerical time control, while the DH-DW16A Type Electric Pattern Bender make helix , and three kinds of basic patterns C, S, P. It is well known that the basic makeup elements of iron craftwork products include four basic patterns C, S, P, E, and five geometrical figures (round〇), (angle∧), (curve∩～), (helix ), (pretzel pattern∝), while the universal pattern bender can make four kinds of basic patterns (C, S, P, E), and four kinds of geometrical figures (round, arc, angle and helix), The machine's emergence can make the iron craftwork process have revolutionary progress. The machine is made with DH-DW16A Type Electric Pattern Bender as the main body, and is driven by the basic shaft of the bender, but it is additionally equipped with the following four mechanisms: arc bending device, angle bending device and small round bending spring device, thus we call the improved machine as DH-DW16B Universal Type Electric Pattern Bender. By the three added devices the DH-DW16B Bender has not only all the functions of DH-DW16A Bender but also the following functions: arc and round bending, strengthening, angle bending, small quantity of small round bending.
