Product Description : The knuckle joint presses are particularly suitable for coining and trimming operations. Compared to an eccentric mechanism, the ram motion has an early slow down in the down-stroke and a late acceleration in the up-stroke, thus increasing the forming and coining phase of the cycle. The energy stored in the mechanism is higher than the standard eccentric presses one and is concentrated in the coining phase of the cycle. The structure of this machine - very compact and particularly rigid - is oversize by design so that it can consistently withstand the extremely strong coining stresses. Results on the product: • All the products are first-rate in order to meet without difficulty the tolerances set by the operator. • Possibility of performing difficult coining operations; easy forming of very hard materials. • The blanked edges are sharp and precise. • Precision in making complex borders. Production advantages: • The long working time is recovered during the very quick approach and return phases. The productivity of this kind of presses is very high as regards as the conventional presses, since the material yield critical speeds are reached with a higher number of cycles. • The lower speed of impact and operation will result, on a same performance basis, in a much longer tooling life. Only the user can decide whether it is better to aim at a higher production or at a longer tooling-life or even reach a compromise between the first two choices, which, compared to conventional presses, will in any way improve the production rate (in case of variable speed of the press). • Reduction of noise and vibrations resulting in a better workplace
