Wire drawing machine and wire release machine - Back tension wire release retrofit -INOVANCE-Advancing Industrial Technology,For A Better World

The current situation

In industrial manufacturing scenarios, especially in cable processing, textile machinery, printing and packaging, accurate tension control is the core requirement for product quality and production efficiency in continuous production lines such as metal wire drawing. Traditional cable disconnection devices rely on brake disks or magnetic powder damping systems to achieve tension adjustment. There are significant drawbacks.

The disconnection of existing equipment is generally achieved through brake discs or magnetic powder damping. Brake discs make significant

When tightening is required, it can be achieved only through manual rotation. There is no torque control.

Regular replacement of wearable parts and general maintenance result in high labor costs.

The mechanical thermal energy generated during the dragging process is wasted energy.

The solution

Use the PID algorithm provided by the MD520 drive to accurately control tension and drive the MV31 permanent magnet synchronous motor + gearbox. The motor is used to generate power in reverse direction under torque control. The energy generated by the AC drive during braking is fed back to the grid through the AFE. In this way, more than 95% of the regenerative energy can be recycled to save energy when the AFE effective braking notification is met

Benefits

Energy saving

When the cable is pulled, the motor generates power and the AC drive feeds back to the grid through the energy feedback unit. In this way, there is no waste of resources and the process is environmentally friendly.

Long-term cost reduction

No supplies are required after the retrofit, which saves material and labor costs.

Optimized noise reduction, improving the working environment

Resolved the problem of loud noise during brake disc running.

Flexible control of forward and reverse jog, improving operating efficiency

Forward and reverse jog for easy operation.
