The Salvagnini S4 punching and shearing machine boasts a series of technological firsts, which have underlined the originality of this highly competitive solution ever since its conception.
These "firsts" include the multi-press punching head, the build in shear, integration in FMS systems, part nesting, brush worktables, unmanned operation, safety features and ergonomic use.
Traditional punching machines have a single press and mechanism that automatically takes one of the punches and its respective die from the tool magazine and moves them into the work position under the press. The S4 instead has as many presses as there are available so that each tool works independently of the others exactly where it is. This principle of a multi-press head with hydraulic distribution of the punching force at the point of use was patented by Salvagnini and makes the S4 unbeatable when it comes to cycle times and tool wear.
Multifunctionality
The combined shear adjacent to the multi-press head, incorporated in a single structure with a single manipulator, makes an extremely compact, high-performance multifunctional system that makes a turning point in a sheet metal handling logistics within the factory. Another advantage on this front lies in the option of operating the machine in line with Salvagnini P4 Panel Benders, with other machining centers or in more complex systems.
The chain comprising the Salvagnini Six numerical controller and the automation software solutions, which have been developed in- house and tailored to these ground -breaking innovations, has always assured operational flexibility as well as high throughout of consistently high-precision parts.
One example is automatic nesting, which applies patterns to several blanks in an unmanned system. Another is the integration of anthropomorphic robots, which work without requiring teaching and can selectively unload small parts.
MULTI-PRESS-NO IN-CYCLE STOPS FOR PUNCH CHANGES
Multi-press head
Salvagnni has 5 different multi-press head configurations, which differ in terms of the number of stations, as indicated in the table below, so as to meet the different production needs of each customer.
Tool changing, where needed, is very quick, taking just a few minutes. It involves manually removing the toolholder cartridges-which run on dovetail slides-replacing the dies and then back in.
