A survey of presses for hydroforming tubes, extrusions: Presses, accessories offer options for hydroformersHydroforming is one of the most important fields in production manufacturing. In recent years many single presses, groups of presses, and entire production plants for internal high-pressure (IHP) hydroforming of tubes and extrusions have been installed, especially in the Americas and in Europe. The driving force behind this development has been the efficient production of automotive parts.

Optimizing a single probe, gap-tolerant, double sheet detector system: A guided tour of its working principles, capabilities, limitationsDetecting the presence of two sheets in a press feeding operation uses scientific principles, but the process is not an exact science. A typical press-feeding situation involves an air gap between the detector and the first sheet in the stack or an air gap between the top two sheets, and these air gaps reduce the detector's effectiveness. Understanding the capabilities of the detector and the limitations imposed by imperfect conditions can help stampers set up an effective double-sheet detector system.

Evolution of the beast: Mechanical presses adapt to meet current stamping challengesThis article outlines how mechanical presses are changing to meet a new marketplace. Stampers are adding extra stations to create a more complete part and stamping harder alloys. Servo-driven mechanical presses will make traditional flywheel presses obsolete because they use less energy and can be adjusted midstroke. Technological advances include real-time press monitoring, automatic die changes, and computerized troubleshooting.

Stamping 101: Anatomy of a Mechanical PressStamped 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. Both force (load) and accuracy are required to achieve the repeatability and tolerance demands.

Retrofitting a prog-die press for transfer operations: Wringing more profit from an old pressConverting a current press to a transfer press requires altering the press, transfer dies, and the transfer system. Some presses are suitable for conversion, some are not. With a proper transfer retrofit, an old press can become a fully programmable state-of-the-art transfer press.

Metal former today, compression molder tomorrow: If you have a hydraulic press, you have a great foundation for exploring a whole new world of composites formingThe difference between a hydraulic press used to form metal stampings and a compression molding press used to form parts out of composite materials isn't that great. Could a metal former make the jump into composites forming? With a lesson in materials handling and some customers, a metal former might be able to make the jump.

The pressure is on: Prolonging die life with the help of sensor filmThe traditional method of measuring pressure distribution in stamping operations—the die spotting blue technique—reveals the pressure points without actual pressure readings, making it difficult to balance in relation to other die components. A thin, flexible, Mylar-based sensor film that instantly captures and permanently records pressure distribution and magnitude between any two mating or contacting surfaces has emerged as an alternative to traditional pressure testing.
