may be a bit expensive equipment, they are also very versatile equipment for a wide range of material thicknesses and widths. Servo feeders can be programmed separately for different stamping dies, so the changeover reduces many settings times.
The servo feed speed is also relatively fast. Of course, the speed is related to the feeding length: the longer the feeding length, the longer the feeding time, which will affect the speed of the stamping process. Even so, the servo feeder does the job well in most of the press feeding.
With a servo feeder, you can set many parameters in one stamping cycle. For example, if you are performing in-mold tapping and the strip can only move within 90 degrees of the press cycle, you can program on the servo feed. It will affect the speed of operation to a certain extent, because you have to complete the feeding in a short time, but again if you can use the other 220 degrees of the stamping cycle, you have more time to feed and can run Faster.
Another outstanding feature is the ability to fine-tune small numerical feeding length while producing tiny, precise pieces. The fourth advantage is that it can be feed in a Z shape, the strip can be moved not only from left to right but also from front to back. The
zigzag type servo feeder
saves up to 13% of raw materials.
The most significant benefit of servo feeder is its ability to sense material feeding resistance. If your stamping die is running, a scrap ejected, or if you have a tap in the mold, a tap breaks, or a punch breaks and gets stuck in the strip and dies. The servo feeder will detect that, stop running and pull back to the previous step.
