Clinching tools and Clinching machine (sheet metal): the clinching technique.
The Clinching technique is an innova琀椀ve process for the mechanical cold junc琀椀on of sheet metal. It
is based on the plas琀椀c deforma琀椀on of the sheet metal you need to join, that is possible through the
interac琀椀on between a punch and a die without the supplement of added material. The punch and the
die, by punctual pressing of the sheet metals with a preconceived force that permits the penetra琀椀on of
the punch into the sheet metals, create a bu琀琀on that form the “point” of the junc琀椀on and shape of which
depends on the tool kit geometry.
PRINCIPAL OF FUNCTION (TYPES OF THE POINT)

•
•
The sheet metals pressed between the punch and the die get deform
forcing the material to extend laterally up 琀椀ll they create a bu琀琀on. The
“point” can be of the trapezoidal type or of the round type which are
realised, respec琀椀vely, with a trapezoidal punch and die or round punch
and die.
Round point allows an herme琀椀c join to be formed, with a resistance to
uniform strain in every direc琀椀on and with an excellent appearance.
The trapezoidal point allows the union of the sheet metals even with a
low duc琀椀lity, moreover, can be applied to the union of more than two
layers of the metal plates.
