| Cold heading machine is a kind of stamping machine in mechanical manufacturing. When raw materials are not changed, the materials are shaped into the required shape. The obvious advantages of variable frequency speed regulation soft start, stepless speed regulation and energy saving are becoming more and more obvious, which has become a trend. technological requirements It can be applied to the fluctuation of +20% of mining power grid Low frequency large torque, capable of low-frequency operation Wide speed regulation range, stepless speed regulation High impulse current and strong overload capacity Strong overvoltage suppression and strong overvoltage capability Complete safety protection functions Program advantages The low-frequency torque is large and the speed regulation range is wide, which meets the requirements of stepless speed regulation and range width of the system It has 110% long-term overload capacity and can withstand the impact of large current in the system Strong current suppression ability, which can meet the stable operation of the system Strong voltage suppression, without adding braking unit and braking resistance Wide range of voltage input to meet the site requirements of large changes in grid voltage The protection function is complete to protect the safety of the system System scheme T600 series frequency converter is selected for the system. The frequency converter sets the frequency by receiving external analog signals, and performs rapid inching and operation through terminals. Excellent performance control ensures the normal operation of the system. Its working principle is that the frequency converter controls the output gear of the motor to transmit power, performs linear motion through the connecting rod mechanism, and uses abrasive tools to deform the embryo of the material. | |||||||
