What are the bending forming process details of sheet metal bending
Recently, I introduced a lot of knowledge about sheet metal bending
processing. Today, I will continue to talk to you about what problems need to be
paid attention to in the sheet metal bending processing and forming process. The
following five aspects are summarized.
Do the semicircle. Make a semicircle on both sides of the bending line first,
which can prevent the sheet metal from protruding due to extrusion on both sides
of the bending Angle after bending. Convex size and sheet metal thickness, the
thicker the material, the more convex, therefore, the diameter of the semicircle
are better than 1.5 times the thickness of the material.
Do R Angle. If you do not make R Angle, after many times of stamping, the
original right Angle will gradually disappear to form R Angle, but at this time,
one side or both sides of R Angle will have a little side length. Therefore,
make R Angle before bending, and the Angle inside should be greater than or
equal to half of the material thickness. If there is no clear requirement a
right Angle, should be processed into an R Angle; In the process of drawing, R
Angle should be marked to avoid damage to the mold when the line is stopped.
Make a narrow or open side hole. In order to avoid rough edges, it is
necessary to make a narrow hole or edge hole at the turning point between the
plane and the bending surface, and the width of the narrow hole should be
greater than or equal to 1.5 times the thickness of the meat.
A discount. The discount edge is divided into unilateral and bilateral,
compared with unilateral discount, the bilateral discount is more accurate, and
the height of the discount edge is greater than 3mm; The parts on the side wall
are required to be more than 10mm from the bottom surface; There are side wall
opening can not be too close to the bottom surface, to keep above 3mm, otherwise
the hole will be deformed by pressure.
It should be deformed after bending. There are two cases of deformation.
First, in view of the deformation formed by the force after bending, without
affecting other parts, can be added in the bending Angle of 45 degrees of
reinforcing additives, increase the strength; Two, because the plate shape is
long and narrow type is not easy to keep straight, bending deformation, which
can be folded an L or folded two inverted "U" type edge, but sometimes will be
interrupted by some factors, can not connect from head to tail, then you can
play the right amount of convex ribs to increase its strength.
