This unit has vacuum and high-pressure forming with steel-rule cutting in the forming tool
plus an additional in-line cutting press and in-line stacking.
The fundamental difference between HPDC and low-pressure casting is that in HPDC, the steel forming tool
can be used repeatedly (generally producing 80,000 parts or more before replacement) whereas the low pressure method usually sacrifices all or part of the tool (made of compressed sand mixed with binding agents) with each part produced.
They're using four lasers in the forming tool
to make certain that the flanges are right.
The change of a sheet metal part's shape after the forming process is driven by the release of internal elastic residual stresses after forming tool
As mentioned, a well-designed forming tool
can be invaluable in producing a repeatable, reliable form.
Other topics include enhanced formability of aluminum blanks by local heat treatment, melted polymer as a pressure medium in sheet metal forming, automating the design of cold roll forming tool
sets, and preventing partial draw-in during high speed deep drawing.
The punching and forming strokes are based on horizontal movement, made by a servo motor, which is converted into vertical ram movement and transmitted to a punching or forming tool
. The turret layout is customer-specific; up to 10 index stations can be added.
A sheet metal part is produced by the movement of a forming tool
in combination with a simplified die.
In the process, the universal spherical forming tool
is moved along the NC controlled toolpath as follows (Fig.
Changeovers including changeparts for the tray forming tool
take only 15 minutes.
Further the upper forming tool
with the angle of 47,5[degrees] was drawn.
