Straight to the point: The importance of straighteners in stamping operations

The straightener, when set properly, removes the coil set, or curvature of the rolled material. If the machine is used or set incorrectly, the coil set can remain in the material, even after being struck in presses with capacities to hundreds of tons. This can cause a variety of problems: out-of-tolerance parts, difficult feed operations that can disrupt and slow performance, and, to some extent, additional wear and tear on feed line components and tooling.

Coil feed line considerations when stamping HSS: Making adjustments for stronger steel

With its higher tensile and yield strengths, HSS is stronger at any given gauge than conventional "mild" steels. Initially, lighter-gauge HSS was used to replace heavier-gauge mild steel to reduce weight in many automotive parts, and this continues to be the most widely used application for HSS. However, as a new trend to run thicker and thicker gauges of HSS continues, stamping fabricators are evaluating their press feeding and coil handling equipment, as well as press tonnage capacities and die designs to ensure that these harder parts can be formed effectively. The dynamics of HSS have a bearing on feeding, straightening, and coil handling equipment.

Stamped components are made by forming, drawing, trimming, blanking, or piercing metal—in sheet or coil form—between two halves (upper and lower) of a press tool, called a die. The upper member (or members) are attached to slide (or slides) of the press, and the lower member is clamped or bolted to the bed or bolster. The die is designed to create the shape and size of a component. The two halves of the die are brought together in the press.
