Choosing the Right Coil Straightener
The coil straightener is basically the core of any wire processing line: it compensates for any undesired deformation of both the strip copper wire and the coil. The perfect coil straightener for the specific application defines the parameters that define the product. This article highlights three critical parameters to consider while purchasing a coil-straightener. These three are the size of the coil-shaped piece, the distance between the centers of the strips and the thickness of the copper wire. The considerations then are how much the equipment will cost, the ease of its use and the level of output.
The first parameter to consider is the size of the coil-shaped piece. The larger the coil, the more expensive the equipment becomes, but it also has greater precision. The smaller the diameter, the smaller the precision, which means the less expensive it gets, though it also has a high level of precision. In most cases, the coil-straightener with a larger diameter also has a higher efficiency than the one with a smaller diameter.
The second parameter to consider is the center distance straightening rolls. The center distance refers to the distance between the centers of the copper strips. The larger the coil, the higher the center distance. The larger the roll, the higher the efficiency; therefore the larger the coil straightener.
The third parameter to consider is the maximum power or the maximum speed that can be achieved through the coil straightener. There are two types of variable speed copper coil straighteners: constant voltage and variable voltage. The constant voltage model includes a motor that is capable of running at a constant speed, which is ideal for applications where the winding of the wire is very fine. However, if the wire is very large or if the wire is very thin, then the variable voltage straightening coil is necessary.
The fourth parameter to consider is the overall length of the coil straightener. If the wire is very long, then the variable speed coil straightener will have a shorter overall coil length. On the other hand, if the wire is very short, then the small and compact constant voltage coil set will be better suited.
The fifth and last parameter to consider is the coil straightener’s quality rating. The highest rating that can be awarded to a coil straightener is a.021. There are different levels of quality, and each level corresponds to a different level of quality of finish and construction.
