Knuckle joint presses

Knuckle joint presses are machines with a rigid structure that ensure the generation of high pressure forces on the slide. In these presses, the drive of the slide is not directly from the connecting rod, but through the knee system (knee joint). The energy stored by the machine mechanism is higher than that of standard eccentric presses. As a result, knuckle joint presses are characterized by very high pressures near the lower reverse position of the slide, high accuracy, low dead weight and compact design and small external dimensions. Lower strokes and working motion speeds increase die life, while machine performance is guaranteed by the very fast approach and return phases of the slider. Due to their features, these presses are mainly used for operations such as punching, marking, swelling, kneading, straightening, extruding, etc.
