Compact and Versatile
A unique concept in high speed, zig-zag roll feeding, the DXY/EV allows parts to be fed in a staggered pattern for optimum material yield. Material is fed in a simultaneous X-Y movement allowing incoming material to travel at high speeds through the rolls on the X-axis. At the same time, the Y-axis movement is controlled by a rotating linear ball screw which maximizes speed and provides high torque and low inertia.

Like the standard single-axis DX/EV Roll Feed, the Zig-Zag feed is compact and can be easily mounted to any side of a press. The roll feed is driven by an AC servo motor while the Y axis movement of the feed is powered by a combination AC motor and linear ball screw. The DXY/EV can be programmed to feed material in a single or dual axis format. It can also be used to push or pull material through the die.

All of the benefits of the DX/EV
Feeds in a single or dual axis format
Delivers material in a simultaneous X/Y movement which allows for high speed operation
Reduces costly scrap by optimizing material yields
Reduces inventory and downtime by standardizing and consolidating material widths
Minimizes set-up time by automatically calculating X and Y axes
Allows a family of parts to run on one press based on a given width
Powerful, yet compact. Requires very little floor space
Mounts to any side of a press
Strip location can be determined by two independently adjustable guide rolls on feed entrance
Permanently sealed, lubricated bearings reduce maintenance problems caused by dust and dirt contamination
Pre-programmed acceleration and deceleration curves eliminate operator input
Dynamic Feeds' proprietary software can be easily modified for special applications
System Set Up Is Easy
The DXY/EV is pre-programmed for easy set up. Enter only four parameters:

1. number of columns per strip (2-out, 3-out, etc.), or material width
2. part diameter
3. web width
4. strokes-per-minute

The controller will automatically calculate the optimum movement in each axis and set up the feed to deliver the material in a simultaneous X-Y movement at high speeds.
   
Production Performance
The graph below represents a standard equilateral punch pattern. Irregular patterns or special feeding sequences can be programmed to achieve varying feed lengths, skips and repetitions.

   
Automatic Punch Calculations
The Dynamic Feeds' standard "Pattern Generator" software is available to automatically calculate your optimum material yield and set up all parameters for the DXY/EV. Application specifications based on a family of diameters at a given thickness can be calculated to:

• show you your projected cost savings
• recommend a family of material widths
• recommend running a given family of part diameters for a given material width
• recommend your best pattern for optimum material yield
