The Dalcos VEGA feeder with two alternating reciprocating clamps is one of Dalcos' renowned innovations, which works very simply with a brushless motor connected to a precision ball recirculating screw with right and left thread. A similar drive system was known back in the 1400s, since it appears in the writing of Leonardo da Vinci!
Dalcos was the first to come up with the idea of applying this mechanism to the two clamps of the coil feeder: the system is in fact covered by international patent.
The two pneumatically operated clamps A and B, connected to the screw, always move in opposite directions. When clamp A is closed, the material advances as far as the stop, where B also closes, followed by A opening. The motor reverses rotation and now it is clamp B that makes the coil advance.
Using two moving clamps has many advantages, such as:
Dalcos VEGA feeders are also supplied separately from the punching lines, since they can work with third party presses and stamping lines.
The version with pneumatic clamps works 0.3 up to 2mm gauge materials, in width ranging from 20 up to 300, 500, 800 and 1000mm.
DALCOS VEGA FEEDER WITH HYDRAULIC CLAMPS
Operation is identical to the pneumatic version, but with hydraulic clamps Dalcos VEGA feeder has even more gripping force making it suitable for materials with gauge up to 3mm. It is available in the same width as the version with pneumatic clamps.
