The NC feeder is the most commonly used three punch feeders with
the highest feeding accuracy, the best stability, the highest
degree of automation and the easiest operation.
The structure is exquisite, the failure rate is extremely low, and
the service life is long. It gradually replaces the mainstream
market position of the roller feeder, and has become the preferred feeder model for the stamping owners to use with the punch press.
Unlike other feeder models, which have only a single main unit, the
NC feeder has two parts: the main unit and the electric control box. The
main unit is mounted on the side of the punching machine with the
mounting plate.
The servo motor feeds the feed roller through the synchronous
pulley, and two sets of pressure springs are used to press the
material at the lower end of the front side, and two sets of
cylinders are used for clamping and loosening the feed roller to
eliminate accumulated error.
NC feeding electrical control box, also known as control box,
control cabinet, is a stand-alone type, there are two types of old
vertical models and new oblique models. The oblique models are
widely used because they are more in line with customer's operation
requirements.
The NC feeding electrical control box is divided into upper and
lower parts. The upper part is the operating area. It consists of a
seven-inch touch screen, operation buttons, control board,
Mitsubishi PLC, signal processing board and isolation module.
The lower part of the electrical component area consists of an AC
contactor, an intermediate relay, a transformer, and a Mitsubishi
driver. It is also equipped with a manual control box that can be
moved for real-time control during feeding and work.
The NC feeding electrical control box is equipped with three sets
of wires, which are respectively a servo motor plug wire connected
to the host machine; a signal wire connected to the punch cam; and
a signal wire connected to the external power source.
Ruihui NC feeder is very simple to operate. After simple feeding, material and
material thickness adjustment, simply input the feeding length,
frequency and speed on the touch screen for continuous production.
