Swaging machine is an industrial metal forming process that can be used to reduce diameters and produce taper, point, or add a flat bottom to round workpieces. It can also be used to impart internal shapes in hollow workpieces with the use of shaped mandrels. This cold working process can be utilized on a wide variety of materials and offers several advantages over other forming methods. It is very cost-effective and provides excellent dimensional control of the workpiece.
The Swaging machine uses two or four split dies that separate and close up to 2,000 times a minute. The dies are mounted on a spindle that rides over rollers. As the spindle rotates, the hammers hit the die halves using cold-force action and a crimp is formed around the workpiece. Unlike a stamp or shear, there is no cutting involved during the swaging process.
A swaging tool must be correctly sized for the size of workpiece to avoid damage and breakage. This is important to ensure the swage will hold up under constant load and will not fail prematurely. It is highly recommended to invest in a quality swaging tool instead of a cheaper one. A good swage will last a long time with proper care. It will require less strength to operate than other swaging tools and will not wear out as quickly.
Depending on the type of work, different types of swaging machines are available. For example, rotary swaging machines are typically used for reducing the diameter of a round workpiece or adding a point to its end. This swaging technique can be used on a wide range of materials and is particularly useful for making pointed ends on bullets or other projectiles.
Another swaging method, hydroforming, is similar to rotary swaging but has additional capabilities. It can be used to assemble components such as cable fittings or to reduce the distance between shoulders on convoluted tubing. It is also used for manufacturing various types of round, square, and rectangular workpieces with a reduced cross-section.
Other swaging machines are used to form workpieces with shallow tapers such as furniture legs, multiple sporting goods, and some products in the aerospace industry. These types of swaging machines can be used on both ferrous and nonferrous materials, and can create a swage that is up to 24 inches in length. This is a great option for situations where the workpiece’s required taper is larger than what can be produced with a standard rotary swager. This type of swaging machine is also known as a long die swager and can be used to manufacture workpieces with very little waste material.
