| Abstract: | To introduce the reformation of the frequency conversion control system of LZ5-6/550 straight wire drawing machine . With intelligent automatic control system of speed adjusting by converter and the control principles,the calculation algorithm and systematic diagram in drawing process are established. Proved in practice, this system can efficiently adjust the waves of anti pulling force and then to keep volume per second of steel wire coming from die box in equal during drawing process. After reformed,the machine can meet the requirements of production. |
