In
stamping automatic production line, no matter which section has trouble, the
entire line will stop. The trimming section is especially easy to have various
troubles. For example, scraps may accumulate around the tooling and cannot get
into the scrap hole, or scraps stuck in tooling or guide chute, etc. The
improper design of tooling may also cause wear and tear on press by scraps
contacting press directly. In eta/DYNAFORM, through the simulation of scrap
cutting and scrap shedding process, the above mentioned troubles can be
effectively avoided and trimming tooling can be modified. This is an indispensable
step in the tooling design stage.
Scrap
Shedding Removal is an add on module which is utilized to simulate scrap
shedding process. The whole process is completed on an integrated interface. The
user does not have to provide any extra data except the practical process
parameters such as motion curve, trim height, angle, practical mathematical
modeling and material parameters, etc., which simplify the operations.
The
typical Scrap Shedding Removal interface is illustrated in Figure 11.2.1, which includes the operation
tool bar, tool definition interface, simulation setup interface and taskbar. The
setup interface consists of four basic pages: Scrap, Velocities, Tools, and
Control.
