The AFE-xDHx line of equipment is designed with the old four-slide technology in mind but without the time consuming intricate setups, costly tooling, and the need for an expert operator. The DH in the model number stands for “Double Head” which means the machine has two individual bending heads. Each bending head positions along a straight wire and bends it according to pre-programmed data.
The user manually sets a straight pre-cut wire to the bender or a wire feeder module (option) automatically feeds the wire through a straightener and cuts the wire to user pre-defined lengths. A hopper mechanism can place straight & cut wire pieces direct to the two benders. An automatic gripper (3D option) can rotate and hold the straight wire during a bend operation. After the part is complete, it can eject to a part holder or an optional robotic “Pick & Place” arm.
The AFE-xDHx machine has four (4) independent coordinate systems.
1) The Feeder / Hopper coordinate
2) The Left Bender and Slide coordinate
3) The Right Bender and Slide coordinate
4) The Rotation Clamp coordinate (on the 3-dimensional models)
Since all coordinate systems operate independently, they can all work simultaneously, synchronized by the Rotation Clamp coordinate. Even with the complicated DH configuration, the AIM SmartEditor® software generates the algorithms needed by the machine controller automatically. The AIM DH machine has built-in algorithms that build the complex motion algorithms!
The AIM user simply enters lengths and angles that comprise the desired part and SmartEditor® does all the rest. However, even the most advanced users can control the exact steps of the equipment, for instance where an intricate part operation requires absolute coordinate programming.
The basic AccuForm E-Series Double Head line configuration includes two benders mounted on two slides and a stationary center clamp. On the basic configuration, the user manually sets a straight (pre-cut) wire for the bend operation adjusting the wire cutter location which could be guided from the benders.
Each Bending head can be programmed to provide 6 moves and directions:
1) Left and right, positioning parallel to the wire, locating the position of a bend
2) Clockwise and counter–clockwise to bend the wire
3) Up or down (recessing for clearance between bends)
4) Bending head 2nd stage up or down allowing selection of two different sets of bending tools
5) Bending head wire clamp rotation (extend or retract), helping guide the wire while bending. When distances are critical, the bending head can be programmed to hold the wire and move it, allowing for smaller bend to bend distance.
6) Bending head wire guide up or down, programmable for flexibility and even smaller bend to bend distances
Center Wire Clamp
The center wire clamp on the AFE xDHx line is stationary and the wire can be moved programmatically using the benders, providing more flexibility and smaller bend-to-bend distance.
1) Center Clamp wire clamping and rotation (3D version)
2) Part eject, in or out, for part ejection
The three dimensional option (AFE-3DHx machines) adds another axis to the system, allowing wire clamp rotation throughout the part program.
Wire Feeding Device:
Used for the feeding and positioning of the wire.
Bending Heads, Hopper and Cutting unit: Each bending head is an independent system controlled by a bend axis and a linear position axis capable of reaching speeds of up to 5m/s and acceleration rates of over 4 g’s. Each side, left and right, belong to independent coordinate systems for production flexibility and speed. They can be synchronized or programmed completely independent.
On the Turret version, the bending heads and tool clusters are supplied with both hard and roller pins.
Linear slide Max. Slide Distance: 1780 mm (70”) Slide speed: 5 m/sec.
Resolution: 0.01 mm (0.0004”) Drive: AC brushless linear servomotor
Bending unit Max. Bending angle: +/- 230º Bending speed: 1600º/sec.
Resolution: 0.01º Drive: AC brushless servomotor
For size 1 we use a pneumatic actuated cutting system. For sizes 2 and 3 we use hydraulic cutting system, providing reliability and longevity for high tensile and heavy cutting requirements. The location of the cutting unit is manually adjustable in order to provide flexibility on the production setup. It cuts the wire to a pre-programmed length and then feeds it to a hopper.
*(Optional: 3D) Rotating Clamp: Constructed of heavy-duty tool steel, rotates the wire when fed into the unit at 700Ëš/s. The rotating clamp holds and rotates the wire around the center of the bender, thus enabling the generation of three-dimensional parts. Maximum part length with a 130° bend is 70” measured from the bend point to the side of the rotating clamp.
Max. Clamp Rotation: 230° Precision: +/- 0.025°
Drive: AC brushless servo motor Transmission: Precision planetary gearbox & belt.
