Zusammenfassung: | The utility model relates to an A. C. electric transmission system for a completely direct drawbench, which belongs to an electric control device of a drawbench for steel wires of metal products. The utility model aims to provide the electric control device of a drawbench for steel wires which regulates the speed of a motor and achieves the goal of causing the speed of the two rotating drums to be matched without though tension or position detection but through detecting the strength change of the motor driving the two rotating drums so as to confirm the change of the tension of the steel wires. The utility model is characterized in that the utility model is provided with an integral circuit composed of a proportioner circuit A, a multiplier circuit B, and an inverted phrase amplitude limiting device circuit C. The utility model increases the running time of the drawbench, improves work efficiency, saves electricity, enhances the bending, twisting, and tensile strength of the steel wire products, and reduces production cost. |
