Functional description
Single-stroke clinching, opening die
The clinching method used by this RIVCLINCH®
machine is based on a single-stroke
method, patented or patents pending world-wide by Bollhoff Attexor S.A.
1. In the first part of the process, the punch will deform the overlapping sheet
material plastically inside a die cavity. The wall of the die, typically split in two,
three or four parts, remains closed.
2. When the lower material sheet reaches the anvil, i.e. the bottom of the die cavity,
the material will flow laterally and take a mushroom shape. In this phase the die
parts will be pushed outwards, sliding on a base. After the punch has been pulled
back and the die disengaged, the die walls will close again, pulled together by a
spring.
The result is a high-quality joint in terms of shape, strength and reproductibility.
A later section will explain how the cycle described above may be optimized.
