![]() ![]() Saw teeth formed in this way are sometimes referred to as being 'set'. A much earlier version of the same operation used a hardened, shaped swage die and a hand held hammer. A clamp attaches a mandrel and die to the tooth and the eccentric die is rotated, swaging the tip. In sawmills, a swage is used to flare large bandsaw or circle saw teeth, which increases the width of the cut, called the kerf. In furniture, legs made from metal tubing (particularly in commercial furniture) are often swaged to improve strength where they come in contact with the ground, or casters. Flared pieces of pipe are sometimes known as 'swage nipples', 'pipe swages', or 'reducing nipples'. Pipe flaring machines are another example. The most common use of swaging is to attach fittings to pipes or cables (also called wire ropes) the parts loosely fit together, and a mechanical or hydraulic tool compresses and deforms the fitting, creating a permanent joint. Heat swaging is a similar process to heat staking, but it involves rolling or reforming a wall (typically a perimeter) of a plastic part to retain another part or component. The swaging is an alternative or supplement to soldering. Typical pin diameter range from 0.017 to 0.093 inches (0.43mm to 2.36mm) or larger. Some pins have a hollow end that is pressed over by the arbor's tool to form a mushroom-shaped retaining head. In printed circuit board assembly individual connector pins are sometimes pressed/swaged into place using an arbor press. Swages are used for shaping the metal in various ways, to enhance its beauty or its fit for a desired purpose. A butt swaging machine can allow a workpiece to be inserted without the dies closing on it, for example a three-foot workpiece can be inserted 12 inches and then the dies closed, drawn through until 12 inches remain and the dies are then released, the finished workpiece would then, for example, be four feet long but still of its initial diameter for a foot at each end. A butt swaging machine works by having sets of wedges that close the dies onto the workpiece by inserting them between the annular rollers and the dies, normally by the use of a foot pedal. There are two basic types of rotary swaging machine, the standard (also known as a tagging machine), and the butt swaging Bluestacks old version download. On a four-die machine, the number of rollers cause all dies to close at a time if the number of rollers do not cause all pairs of dies to close at the same time then the machine is called a rotary forging machine, even though it is still a swaging process.Ī variation of the rotary swager is the creeping spindle swaging machine where both the spindle and cage revolve in opposite directions, this prevents the production of fins between the dies where the material being swaged grows up the gap between the dies. The rollers are larger than the cage so as the spindle spins the dies are pushed out to ride on the cage by centrifugal force, as the dies cross over the rollers they push the dies together because of their larger size. The spindle is mounted inside a cage containing rollers (looks like a roller bearing). This action is achieved by mounting the dies into the machine's spindle which is rotated by a motor. Grease is often used to lubricate this swaging process, which is also called roller swaging.Ī swaging machine works by using two or four split dies which separate and close up to 2000 times a minute. The flaring is done with a pair of rolls that travel around the hole and are fed down into the part, deforming the metal in a controlled, predicted way. ![]() Swaging a bearing into a housing means either flaring its groove's lips onto the chamfer of the housing, or flaring the housing's material over the edge of the bearing. It can also impart internal shapes in hollow workpieces through the use of a mandrel (the shape must have a constant cross-section). Rotary swaging is usually a cold working process, used to reduce the diameter, produce a taper, or add a point to a round workpiece. Swaging is normally the method of choice for precious metals since there is no loss of material in the process. Tubes may be tagged (reduced in diameter to enable the tube to be initially fed through the die to then be pulled from the other side) using a rotary swager, which allows them to be drawn on a draw bench. This process is usually called 'rotary swaging' or 'radial forging'. The second category involves two or more dies used to hammer a round workpiece into a smaller diameter.This may also be referred to as 'tube swaging'. The first category of swaging involves extrusion of the workpiece, forcing it through a confining die to reduce its diameter, similar to the process of drawing wire.As a general manufacturing process swaging may be broken up into two categories: ![]()
