Torrington Forming Machinery developed a standard modular system to swage wires of all lengths. This system includes a feeder and an extractor, both semi-automatic, because the whole part needs to be swaged. If this is not the case, the extractor isn’t needed. For long parts, roll feeders are used. For shorter parts, a gripper feeder is used in front and a collet extractor at the back. In the video below, a roll feeder has been used in front and a collet extractor at the back. This combination allows to swage short parts and medium-long parts. In this case, this was necessary because a short blank was swaged multiple times which greatly increased its length after each step. By combining standard modules like in this example, Torrington Forming Machinery can accommodate all your needs in wire swaging. If the production volume is great, magazines can be added for fully-automatic production.
1047 dual rotary SWAger
Torrington Forming Machinery designed and produced this machine for very heavy applications. Like a standard 1047 rotary swager, it can form bars up to 1 3/8 inches diameter and tubes up to 3 1/2 inches diameter. What makes it so special is that it can form materials with very low ductility like tungsten. The difference with the standard swager is that it applies very low torque on the part. To do so, the head and the spindle are both spinning in opposite directions, allowing the spindle to spin at a lower speed. This method reduces torque on the part but not the number of strokes required to form low ductility materials. This machine was also equipped with semi-automatic feeder and unloader that could accommodate parts
more than 2 feet long.
Suture needle forming and sharpening machine
A very interesting project was the manufacturing of a machine to produce suture needles. Three needles were loaded form a cassette magazine on a three spindles module. A conveyor circuit was moving the modules from station to station. The body of the needle was formed square with two consecutive SS swagers and the tip of the needle was formed in a triangular shape with a third SS swager. Then, the needles were sharpened by three diamond belt stations. The three faces of the tip of the needle were sharpened by a moving plateau raising the belt to the needles and following a specific pattern for each face. Finally, the needles were unloaded from the spindles module to a curving station.
Multi-forming and machining station machine
This next video shows a production line for tubes with double-D reductions on both ends. This machine was taking the blank tube from a slope magazine with a two grippers pick and place manipulator to bring it in a push-pull forming station. At the same time, a partially formed part was moved from the push-pull station to a waiting station. While passing the part to the waiting station, it was rotated to form the other end in the next forming station. The part was brought using the same type of pick and place manipulator through three push-pull forming stations, one milling station and two drilling station before exiting the machine.
Solid shaft forming machining machine
Another example of automotive industry project was the machine to produce a spline-serration solid shaft. The blank shaft was taken from a slope magazine by a two grippers pick and place manipulator to be loaded in a three cylinders push-pull forming station. In that station, the shaft received at first a spline forming on one end and a serration forming at the other end. The same pick and place was taking a formed shaft to a waiting station. From this waiting position, a transfer station picked the formed shaft and loaded it in a machining center through a gate door. Once loaded, the machining center was automatically started. After the machining program was executed, the shaft exited on a conveyor.
