Machine Specification for Stock # 8345

DIECO MULTI-AXIS CNC TUBE BENDING SYSTEM


General Specifications
Unbundler:
The unbundler will be capable of tubes up 72 inches long, and
will accept up to 800 tubes in the 7/8 inch diameter size. Our
unbundler normally incorporates metallic belts for lifting the
tubes and metal chains. To avoid damage with your prepainted
product, we would use nylon straps and plastic chains,to avoid
any damage to the coatings
Seamfinder Station:
The seamfinder station will incorporate a Roland magnetic anomaly
detector, as we commonly use in our seat frame systems. We will
modify the system to accommodate your prefinished tube.
Transfer:
Removes straight tube from the seamfinder and places it in the
bending station.
Bending Station:
Consists of 3 independently controlled compression style bending
heads. With the style of bend head proposed, which is our standard
design, the follow die is held against the tube, while the bend arm
"wipes" the tube around the form die. There is no sliding motion
between the tooling and the tube, which will serve to protect the
coating on the tube. This method will also avoid the heavy clamp marks
which are currently evident on your products.
Each of the three bend heads will be under separate servo control for
bend angle,allowing simple modifications to correct for spring back.
In operation,the tube will be placed in the bend station,where it will
be clamped in the center bend head. The outer two bend heads will then
move into position and clamp the part, and form the outermost two bends.
These bend heads will then release, allowing the center bend head to
form the central bend, completing the part.

GENERAL SPECIFICATIONS (cont'd):
This method ensures that the bend-to-bend distance is held very accurately,
while still maintain a rapid cycle time. The distance between each bend
head is manually adjustable (although we can automate this adjustment),
and the central bend head is adjustable in rotation, to allow the orientation
of the central bend to be "fine tuned". It is not intended that the last
adjustment be used other than for initial setup purposes.
Transfer Unit:
Removes the finished part from the bender, reorients it, and places it in
the tooling module.
Tooling Module:
In which the part is flattened,pierced and end trimmed. This station consists
of two hydraulic presses to flatten the ends of the part, pierces the pivot
hole, and trim the end. These presses incorporate dies which will engage the
tube prior to flattening,ensuring that the flattened area is centralized in both
directions. These two units are mounted on slides, offering easy adjustments
to accommodate different widths and lengths of parts.
The pierced holes for the feet will produced by 3 standard piercing units;
2 of which are mounted on the same base as the end form presses. Thus, as the
end form presses are adjusted to accommodate different widths of parts, the
two holes near the outboard bends are also adjusted. The third piercing unit
is mounted on a slide conforming to the shape of the part, with a screw adjustment mechanism to raise and lower press according to size of the part. These piercing units and flattening presses contain compact die sets, which can be rapidly changed to accommodate the 3/4 inch and 7/8 inch diameter tubing included in your program.

Equipped With
Hydraulics & Controls System: Consisting of a hydraulic system, valves, switches
for all motions, computer based control system and a touch screen man-machine
interface. The control system incorporates diagnostic messages for all errors,
and a setup screen to allow the bend angles to be quickly adjusted. The screen
will also include complete setup instructions for each part.

We estimate the changeover time between frame sizes for a given tube size to be
10 minutes, with one operator. Changing the tube diameter involves changing the bend dies, as well as the inserts in all the presses. We estimate this will take 20 to 30 min.
