Tube Swaging Machines
Tube swaging machines are used to permanently join pipes together by putting the pipes under high pressure or by pressing them into a die. Unlike traditional metalworking, which relies upon heat, tube swaging machines use cold metalworking processes to form metal. Since swaging is a forming and not a machining process, it results in no wasted metal scrap in the shaping of pipes.
During tube swaging, the tubes are fitted together by increasing or reducing the size of the tube’s diameter at the end of the pipe. This shaping is achieved through a repeated hammering motion. The ends of tubes can also be flattened, slotted, notched, flared, flanged, or punched. Using the swaging process, tubes and pipes can be joined together quite easily.
In order to fit the tubes together one tube is forced into a die which compresses the end of the tube. Now that this tube has a smaller diameter it can fit into the end of another tube. The two tubes are connected, and a compressive force is applied to the joint to permanently seal them together. This process can be used to create a cohesive system of tubes and pipes or to attach a variety of different pipe fittings.
Rotary swagers, long die swagers, and pipe flaring machines are some of the different designs of tube swaging machines. Swaging machines are used on tubes made from a variety of metal materials, including steel, aluminum, brass, copper, titanium, and stainless steel. The tubes made by swaging machines are used in the aerospace, automotive, construction, marine, medical, and military industries.
