Miyazaki Machinery System / COMBINED DRAWING LINE

Example of wide selection

Machines systems designed with your needs first in mind.

Miyazaki offers a wides assortement of machines for the combined drawing line-many more than we can shou you here. Our long experience as a full-line wire machine maker has resulted in a wealth of in-house technology which has been implemented in our advances electro-mechanical systems. Contact Miyazaki and find out how we can put together a combined drawing line that can lower costs, increase quality, and boost productivity.

COIL PAYOFF STANDS

Single or double swift coil payoff stands can be equipped with self-drive mechanisms as well as swing down, raise and position shift functions that can speed up your line and increase efficiency.

COIL OPENERS

Coil openers speed up and simply wire loading by automatically pulling out the end of large diameter wire coils.

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.

Upright-type pre-straightener	Pre-straightener for smaller wires
Shot blast descaler integrated in-line	Straightening roller position control system The straightening roller position control system automatically returns each roller to its home base position through motor drive. Position data is kept in memory and digitally displayed.

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.

Drawing units

The natural rotational action of the drawing cam is converted into a linear motion to drive the draw carriage.
Wire is gripped by the jaws in the carriage and pulled through the drawing unit is also available for smaller diameter wires.

Straightening units

Bars exiting the draw dies are straightened through vertical and horizontal rollers.

Dual spinner units

The spinner straightening unit uses five rotating nozzles that pull the bar straight.
The middle nozzle can be externally adjusted while the machine is running.

Polishing & straightening units

Polishing and straightening units uses two disk pairs equiped with from five to seven nozzles that simultaneously straighten and polish the bar.

DISK & NOZZLE TYPE

2-roll straightener

The 2-roll type uses over-and-under rollers to straighten and polish the bar.
Roller pressure is automatically adjusted.

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.

Elevating system cradle

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.
