Combined Drawing Machine

On the job 24-hours a day

The Miyazaki combined drawing machine line was developed to provide higher productivity, improved quality, and greater bar yields while contributing to a quieter and more worker-friendly factory environment.
More importantly, Miyazaki gives you years of trouble-free operation, the key to name Miyazaki is becoming associated with the best performing combined drawing lines available today.

Miyazaki Special Wide Selection

The main part of the combined drawing line is the drawing unit which is driven in a liner motion through a rotational drive action.
Miyazaki makes four different types available. Single cam, double cam, or flange cam drive unit is also available for smaller wire diameters. Miyazaki gives you a wide variety of process configurations to match your exact needs.

PRE-STRAIGHTENING UNITS

The pre-straightening unit performs initial wire straight-ening for the wire fed up to the drawing die.
Final bar straighteness is assured because residual coil stress is released before drawing.

Hydraulic push pointer

The push pointer mechanism uses hydraulic power to insert the wire end into the drawing die (for wires over 15mm in diameter).

Carriage type

Swaging machines

By installing a swaging machine in the production line, energy savings in the implemented.

Bar delivery tables

After bars are drawn, straightened, sheared, and polished, they are deposited in the bar delivery table.
Miyazaki delivery tables use various devices that prevent the bars from being scarred or scuffed.

2 way type V trough delivery type

Ejection type delivery table

1 way type L-shaped delivery type

Chamfering units

By using transfer technology during transport, impact on the product has been completely eliminated.
Change in bar diameter, length, cutting depth adjustments are entirely handled through graphical interface; up to 100 different configurations can be registered.
According to your needs, chamfering units can come equipped with a shearing device.
Depending on the delivery setup, they can also be operated off-line as independent devices.
