Standard (single stage) Bending Head
The feeder module is feeding the wire, through a straightener, to the Bender module. The bender mechanism bends the wire, according to pre-programmed data and “shears” it with an integral hydraulic cutter. The turret option (-T) adds one servo axis to the Bender module, for automatic and programmable bending tool-change along with a second bending pin. This provides the flexibility to programmatically change the tool that the wire is getting bend on, making available 4-8 different bend radii. Two Bending pins are available with the turret option; usually one is a roller for generated radii and the other is a hard pin for “tight” bends.
Turret Bender (Indexing Tool changer)
Optionally, additional modules can be added to the configuration of the machine depending on the specific production requirements, for example in-line Chamfering Module (AL1) or in-line die module (AD1). Plenty of modules are available and our engineering team is creating more every month in order to satisfy every request from our customers. Please refer to the Modules & Accessories pages for more options.
In order to get familiarized with our concept of wire bending and to better understand the principals that we use, we will describe a simple right angle, 90-degree wire bend operation with the following steps:
The feeder module feeds the first length of our wire sample
The bender is positioning to be ready to operate at –30 degrees position.
The Turret is positioning to the pre-selected tool position
The bending Pin engages
The bender locates at the required position in order to provide a 90-degree bend to the wire.
The feeder feeds the second length of our sample part.
The cutter “cuts” the wire.
The above steps are really simple and also familiar to anyone that has worked with wire bending. In conventional programming, a CNC user would have to enter in a computer, all of the above steps individually. Now let’s try to speed up the above production: We need the first four steps to be done at the same time and we do not want to worry where we have to position the bender (besides the fact that we need a 90 degree bend). Although this would seem complicated, our SmartEditor™ software generates the algorithms needed by the motion controller automatically. We have built an algorithm that builds motion algorithms! All of the above steps can be represented with just three numbers and a bend radius (tool selection). The user programs what he or she needs to do and not what needs to be done!
The user simply enters lengths and angles that comprise the desired part and SmartEditor™ does all the rest. User intervention is allowed if an intricate operation is required as well as absolute coordinate programming, for the more advanced users, where one can enter the exact steps of the equipment.
Besides the simplicity of the programming, exceptional is the machines’ construction. Since high speeds can be accomplished, the main frame is constructed out of solid steel plates for improved stability, minimizing vibrations and increasing speed and accuracy of the equipment. The weight of the AFM-V1 is approximately 1500 Kg. (3,300 Lbs.). Using the latest technology servomotors, the feeder and the bender can rapidly accelerate to maximum speeds, and depending on installed options, provide the fastest production rates in the market.
AFE-2Dx Machine Details
For Wire Detail Specs please see:Wire diameter Range, Wire Tensile Strength Capacity
(1.3) Two Plane Wire Straightener:
Every machine is equipped with a two-plane wire straightener.
On size #1 machines each plane consists of 9 “V” groove roller bearings; 5 are stationary and 4 are adjustable.
On size #2 machines each plane consists of 11 “V” groove roller bearings; 6 are stationary and 5 are adjustable.
Two different diameters of rollers allow straightening a wider range of wire with just one set of straighteners.
Please consult table for applicable tensile strength / diameter properties.
