Swaged fitting begins at the end closest to the hose and reduces the ferrule as it moves toward the fitting, halting around 3/4 of the way up the ferrule to create a bell region that makes a pocket for the extra hose to flow into.
To lower the OD of the ferrule and compress the hose into the stem serrations, swaging involves a machine pushing a fitting and ferrule through a fixed split die bed.
A hydraulic swaging tool must force the fittings into the wire when using a hydraulic swaging fitting.
A hydraulic fitting requires the wire to be placed into its barrel before the fitting is pushed (swaged) to the wire.
What is Swaging?
Swaging was first used in England in the 19th century. It is the procedure for swage shaping. The curved tool known as a swage is used to bend or shape an item into the desired shape.
Swaging has a range of uses in the metalworking industry, often known as metallurgy. Swaging, a term, is the process of pressing or pounding metal into the desired shape.
Swaging is the process of giving anything a ridge, groove, or mold-like form. Rods, hoses, and tubes’ diameters may change due to the procedure.
Pipefitting, hose fitting, and ornate metalwork are a few examples of swaging. The casters on a chair or other furniture legs serve as an illustration. Look at the lovely silver coffee table with curved legs that gives it an antique appearance in the conference room at your place of business. Those legs were made by the swaging method.
When used as a verb, Swaging flattens any rivet by pulsing a swage. Continuous rolling motions are used to accomplish this.
Swaging is another technique for fusing metal parts. Aircraft control wires are a prime illustration of this. To meet various size requirements, the ends are molded together. Swaging is an alternative to soldering a wire into position, such as in a circuit board.
To fit into position, the straightened wire needs to be bent. Swaging is the term for this reshaping. In actuality, fittings are typically attached to cables, pipelines, or other components of a similar kind via swaging. The process of swaging generally is used when soldering pieces together.
In all accepted definitions, swaging can be divided into the internal, external, combination, or dual variants. Internal swaging can increase the flow area through tubing or hoses and give hose material traction.
The size of the relevant items is increased by this swaging method, which also significantly reduces the likelihood of bacteria building up near the hose or tube’s end. Offering robust mechanical adhesiveness and bond also aids in reducing turbulence.
As the name suggests, the opposite of internal swaging is external swaging. Combination swaging is similar to external swaging for welding the ends together. Additionally, it has a better cost-effectiveness rating than external swaging. Combination swaging entails reducing the size of objects to suit the need.
Dual swaging includes compressing both aspects by the same amount while using both internal and external swaging.
You may find swaging in products all around you. Car design, keyed musical instrument maintenance, circuit boards, hose fittings, pipe fittings, lock bolts, sawing blade teeth, ammunition, and ornamental metal objects are a few examples of typical applications.
What is a swaging machine?
For those in the know, our clients have asked about hose assembly equipment using terms like swager, press, crimper, squeezer, and swagging machine over the years.
What are swaging tools used for? In plain English, they apply enough pressure to attach the flexible hose to metal fittings.
The machines exert stress on the ferrule’s outer diameter in eight contact regions in a 360-degree circle. The ferrule’s inner ridges bite into the hose as pressure is applied, causing the OD to shrink and locking the connection.
Swaging machines come in a variety of sizes and types, with some being wholly automated for high-volume hose assembly manufacturing. Simple, portable, hand-operated devices are frequently used for service level/piecework requirements.
Conclusion
In that pressure is applied externally with a tool for a swage fitting and is maintained by a sleeve once the device is taken off for a crimp fitting, they are identical.
