Roller feeders are well-known in the stamping industry for their cost-effectiveness, reliability, and speed. They are widely used and loved by many clients. Let’s talk about the two main ways roller feeders are used.
How Roller Feeders Are Installed
Method One: Die Feed Port Installation
This way is perfect for medium and thick materials. The roller feeder is set up at the die feed port of the press. When the right moment comes, the press moves the metal sheet from the waiting coil into the press by one stamping pitch. Then it waits, ready for stamping.
Method Two: Die Exit Port Installation
This method is used for thin materials. Here, the roller feeder is positioned at the die exit port of the press. When the right moment arrives, the press moves the metal plate from the waiting coil forward by one stamping pitch. Then it stops, waiting for stamping.
Both of these methods work well for thin, medium, and thick materials, as long as the metal strip being stamped is stiff enough. If the metal strip isn’t stiff, or if it’s very thin, it can cause the roller feeder to buckle. This can create overlap and disrupt the production process when the material meets resistance during feeding.
Improving the Process with the Thin Plate Roller Feeder
To solve the problem of stamping thin plate materials, we use a specific roller feeder that uses a method called bilateral feeding. This means having one roller feeder at the entrance and another at the exit of the press die. These two feeders are connected by a tie rod, powered by a disk and a rod installed on the press output shaft.
When the press output shaft rotates the disk of the roller feeder, it creates a force that moves the primary feeding mechanism. This then moves the secondary feeding mechanism through the tie rod. The movements of the main and secondary feeding mechanisms are synchronized, which keeps the metal strip level and prevents overlap and buckling of the material.
In summary, understanding how to properly use and install roller feeders can greatly increase the efficiency of stamping operations. With the innovation of bilateral feeding, we can efficiently manage even materials with low rigidity.
