AFE-xDHx Machine DescriptionThe 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.Bending HeadsEach 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 ClampThe 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.
Optional Accessories: For a complete automated production line, the following options are available:
1) Automatic wire feeder with Dual Opposing Rotary straightener module (RSx) which includes:a) Automatic speed wire payoff unit for up to 2,000 Kgr (4,400 Lbs)b) Wire pre-straightenerc) Rotary wire straightenerd) Wire Feedere) Wire length measuring devicef) Pneumatic or Hydraulic wire cutterg) Straight wire transfer mechanism
2) Automatic wire magazine feed with Hopper module (RMx) which includes:a) Wire magazine for 50 wire length pieces, 3m long (pre-cut) at 6mm wire diameter (will fit more pieces at smaller wire diameters)b) Wire transfer mechanism
3) Option: DBCX, -Allows for cutoff of the wire piece at the right of the center clamp. This is ideal for making high quantities of symmetrical parts. On 6mm machines this includes hydraulic unit for cutoff of the wire. Minimum cut length on each end is 2 times the wire diameter. Requires option RSX.
4) BT3DXXX- Bending Tools – full set for left and right bending heads, includes bending pins, center clamp tools, center bending tools, and four feeder rollers.
MT3DXXX- For machines equipped with wire magazine with hopper option (RMx), includes one set of Bending Tools and transfer grippers and magazine inserts.
ST3DXXX- For machines equipped with Rotary Straightener Option (RSx), includes one set of bending Tools and one set of transfer grippers and arbor straightening dies.
