NC servo feeder also known as servo feeder, it is PLC, servo motor, servo driver and other automation equipment to achieve accurate feeding.What is the NC servo feeder?NC feeder usually according to the different relaxation action, is divided into pneumatic NC feeder and mechanical NC feeder these two categories, the two types of feeder feeding principle is exactly the same, NC servo feeder mechanical relaxation with pneumatic relaxation what is the difference?

Feeding machine often to relax the different ways to divide, often divided into: pneumatic relaxation and mechanical relaxation of these two.Different products and different molds require different ways to relax in order to achieve high efficiency.This requires the selection of different models to achieve the effect, mechanical NC feeder relax fast, relax the short distance is particularly suitable for short step distance of high-speed feeding, and pneumatic NC feeder is not limited by the travel, can meet the long time to relax the demand, especially suitable for large molds and non-high-speed stamping.The biggest difference between mechanical relaxation and pneumatic relaxation of NC servo feeder is the difference in relaxation mode. The following is the difference between them:

Mechanical  NC servo feeder:

Adopt the mechanical type to hit the pole to relax, relaxes quickly, does not crush the material, the adjustment is convenient, relaxes is not subjected to the outside disturbance, when needs to relax when carrying on the test mold or the material enters the mold again, only needs to adjust relaxes the screw to touch the perlin to cause the material to relax, the operation is simple and convenient.

Mechanical NC feeder is through the press slide block with relaxed rod device, when press the slider downward, consists rod down the relaxation of the feeder fuselage perlin implementation roller relaxation movement and its use because of its need to punch by adding auxiliary equipment on the slider, so the limitation on the collocation of punch a little, but the advantage is that relaxation fast, very suitable for a short step from high-speed processing production situation.

Pneumatic NC servo feeder：

The cylinder is used to pull the upper roller of the feeder to realize the relaxation. In this process, the CAM of the punch machine needs to send the rest signal to the solenoid valve, and the cylinder action is controlled by the solenoid valve, so that the NC feeder can achieve the relaxation state.Therefore, the pneumatic release device is slow to relax, easy to be affected by the external air source power supply and electronic accessories, and the pneumatic feeder can not be used for high-speed feeding, and in the operation adjustment is also relatively complex.When testing the mold or changing the material to enter the mold again, because this process needs to loosen the material for many times, every time the pneumatic NC feeder relaxes, it needs to control and relax in the electric control box, the adjustment is not as simple as the mechanical type.

Pneumatic feeder is by connecting the relaxation of the punching CAM NC group, provided by the relaxation of the punching CAM to the feeder solenoid valve relaxation signals, finally through the solenoid valve control cylinder push or pull to relax on the cylinder dynamic action, relax the loosening action is relatively slow, but the advantage is that no need to add additional accessories, wide application scope.

Pneumatic feeder is by connecting the relaxation of the’m CAM NC group, provided by the relaxation of the’m CAM to the feeder solenoid valve relaxation signals,Finally through the solenoid valve control cylinder push or pull to relax on the cylinder dynamic action, relax the loosening action is relatively missile.But the advantage is that no need to add additional accessories, wide application scope.
