In the feeding machine, the automatic feeder for power press
has different relaxation methods due to the actual needs of different customers. There are two common types, one is mechanical relaxation and the other is the pneumatic relaxation. What is the difference between the two ways of automatic feeder for power press
? Let's take a closer look at mechanical relaxation and pneumatic relaxation.
I. The pneumatic relaxation for automatic feeder for power press
Pneumatic relaxation of the automatic feeder for power press uses the cylinder to pull the roller on the feeder to relax. The relaxation process also needs to cooperate with the punch. When the punch cam sends a signal to the solenoid valve, the NC servo automatic feeder for power press controls the cylinder action through the solenoid valve, to achieve the NC automatic feeder for power press relaxed state. Compared with mechanical relaxation, the pneumatic relaxation device is slow and susceptible to external air source power supply and electronic accessories, so the pneumatically relaxed NC servo automatic feeder for power press is not suitable for high-speed feeders, and some operational adjustments are also more complicated. When the mold is being tested or the material is replaced, because the process requires multiple relaxations, the pneumatic NC automatic feeder for power press needs to be controlled on the electric control box for relaxation every time. The adjustment is not as simple as mechanical.
II. The mechanical relaxation for automatic feeder for power press
The mechanical relaxation for automatic feeder for power press is using mechanical rods to relax. The mechanical relaxation device should be installed on the punching slider to relax the rod. The mechanical relaxation method has the speed of relaxation, no crushing, damage to the material, and the adjustment is easy to adjust without electrical control. When trying to retest the mold or replace the material, simply adjust the loose screw to touch the Palin to relax the material, and the operation is simple and convenient.
The Difference between Pneumatic Relaxation and Mechanical Relaxation of Automatic Feeder for Power Press
So what is the difference between the pneumatic relaxation and mechanical relaxation of automatic feeder for power press? How to choose when pairing with a punch? First of all, we must combine the actual situation, according to the production needs and the characteristics of the press. Pneumatic relaxation does not require the installation of other accessories on the punching machine, so there will be no installation problems during the installation process. All presses can be used together, or they can be added to a shearer or other equipment for feeding. However, because the pneumatic relaxation is slow, it is not suitable for high-speed feeding operations with short steps. When installing the mechanical NC automatic feeder for power press, mechanical rods need to be installed on the slider for relaxation, so it is not suitable for gantry punching and shearing machine equipment, but the mechanical relaxation device has a fast response, which is very suitable for for short step and high speed feeding operations. Besides, the mechanical relaxation stability and ease of operation are better than the pneumatic NC automatic feeder for power press.
