Pneumatic relaxation of the stamping servo feeder uses the cylinder to pull the upper roller of the feeder to achieve relaxation. The relaxation process also needs to cooperate with the punch. When the punch cam sends a signal to the solenoid valve, the nc servo stamping feeder controls the movement of the cylinder through the solenoid valve. , to reach the relaxed state of the nc stamping feeder.
Compared with mechanical unwinding, the speed of pneumatic unwinding device is slow, and it is easily affected by external air source power supply and electronic accessories. Therefore, the pneumatic unwinding NC servo stamping feeder is not suitable for high-speed feeders, and it is also relatively in some operation adjustments. It’s more complicated.
When trying the mold or changing the material and re-entering the mold, because this process needs to loosen the material many times, the pneumatic NC stamping feeder needs to control the relaxation on the electric control box every time, and the adjustment is not as simple as the mechanical one.
Advantages of High-speed Roller Feeder
1. The structure of the roller feeder is the same as that of the one-way device, which can ensure precise control of the lower wheel, high durability, long use time will not affect the lower wheel accuracy, and stable use. Moreover, there will be no phenomenon that the brake is lost due to the residual oil splashed during stamping, resulting in the reverse rotation of the lower wheel and inaccurate feed distance.
2. The roller feeder will not generate high heat during operation. Superhard alloy and rollers are used on the rollers, which are not easy to wear.
3. The roller feeder operates as a circular motion of the rollers, rather than a linear motion like the 4 guide pillars, so there will be no seizure phenomenon.
4. If the roller feeder is equipped with a reverse device, the speed can reach 30 m/min, generally 20 m/min, which improves the efficiency by 50%.
5. The roller friction force of the roller feeder is small, the required transmission torque is relatively reduced, the transmission mechanism is less likely to be damaged, and the service life is long.
