Sheet and flat metal stock are formed into rounded pieces using metal rollers. Hoops, cylinders, cones, or mixtures of all these forms are possible for the final configurations. They come in several sizes, ranging from tiny bench-mounted manual crank devices to enormous motorized ones. A set of three steel rollers with their long rolling axes parallel and rolling centers creating a triangle make up a metal roller design (see diagrams/illustrations). The amount of radius shaping on each pass is frequently adjustable by the operator by adjusting the distance between the rollers that engage the workpiece.
The rollers’ parallelism can be altered to create cone-shaped patterns. The manual units use lighter, smaller workpieces to carry out the same processes as the motorized machines. When the operator controls how they work, serious harm is reduced. Unless otherwise specified, the term roller will include both hand and motorized metal rollers for this procedure.
There are numerous possible risks linked with using a roller, as there are with all shop tools. Powered rollers are classified as Class 5 tools, while manual rollers are classified as Class 2. The use and operation of rollers are related to a variety of specific risks.
To grip the workpiece, in-running nip points are a fundamental component of the metal roller design. Employees must be conscious of the risks, keep a safe distance, and remain focused on the task because the nip tip is not protected. The infeed is entirely controlled by the operator’s actions on manual machines. It can be stopped promptly at the first sign of trouble. The nip opening is small. It is usually less than 14″ on these machines. The casing with motorized rollers is different.
