NEW QUICK CHANGE TOOL PACKAGE
01/09/2017
The concept of performing tool change in the shortest possible time
represents an undisputed necessity for modern industrial manufacturing of cold
forged parts, even made in smaller lots, making the forming process more competitive against
traditional machining methods.
In developing the tool change
system, SACMA made it without compromising the rigidity and the reliability of the machines.
The CR quick tool change system, standard
for machines series 3, 4, 5 and 6, for both progressive and combined headers, allows an easy removal of the
die block, hydraulically clamped, and the same for the punch block
bolster with the wedges and the complete transfer unit.
A new QTC Package is available to improve the production efficiency as an
option to equip the machine with one or more set of die box, punch bolster
plate with the wedges and transfer unit. Two trolleys are supplied together
with the punch bolters and the die boxes:
1) Punch bolsters on service trolley
The trolley is made in two
pieces. It is possible to handle the upper one with the lifter and move to the
tool room easily .
There are nr 2 positions : top ,
for the punch bolster with the new tools , ready to be placed in the machine
using the flag crane ; bottom , for the punch bolster coming from the machine.
After moving the top bolster in the machine, the disassembly of punches is done by sliding out them from the
punch holder to the plate at the same
level.
The wedges are together the punch bolster,
making possible the complete set up of tools outside the machine, including the
adjustment of the wedges.
The change of the trimming wedge
to the forming one and vice-versa is also done outside the machine, when
necessary. The punch bolster is fixed to the main slide by mean of quick
releasing bolts ,using a pneumatic screwdriver.
2) Die boxes on service trolley
The concept of the trolley is the
same of the punch bolster one.
Two pieces for easy handling and
two positions : top, for the die box to be mounted in the machine and bottom for the die box dismounted from
the machine.
The fixing of the die box in the
machine is done automatically by hydraulic cylinders, integrated with the main frame.
When the machine is equipped
with the TSAP (Transfer Support
Assisting Package) the complete set up of that device can be done outside the
machine.
3) Extra
transfer
In the size 4 and 5 machines the
extra transfer is placed in the suitable sliding shelf over the operator platform. A supporting jig is supplied to
fix the extra transerf for the change and the centering operation of the
fingers. That jig should be placed by the user in the working table over the platform
or in other comfortable position at floor .
In the size 3 machines the extra
transfer should be placed directly in the supporting jig over the working
table. The jig for centering the fingers, both inside or outside the machine, is also
supplied.
The transfer can easily be
dismounted from the machine by activating
two hydraulic cylinders .In the size 3 machines there are two quick
releasing pins.
Did you know? The SACMA Combined
headers maintain all the mechanical and performance qualities of the
Progressive headers, from which they derive. The heading station is exactly the
same than the progressive header. It is therefore possible to make the quick changeover
as on the progressive headers and make different parts than bolts and screws as
special net shape parts. This demonstrates the unique real modular system
making our well-earned reputation of versatility, quality, precision,
reliability and longevity providing the best value for your investment.
