Controlling slug pulling

Controlling slug pulling with hole lapping

January 15, 2008 | By Wilson J Cubides

Diemakers have several options for slug-pulling problems, such as knockout pins, vacuums, punch or die dulling, oil viscosity, wire EDM hole slots, punch/die clearance changes, edge shearing, mechanical grippers, air jets, and cuped-shaped punches. Another method to help stop slug pulling is bell- mouthing the die, which essentially involves cutting a funnel shape around the hole.

Optimizing a single probe, gap-tolerant, double sheet detector system

December 11, 2007 | By Fred Goronzy

Detecting 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.

Tooling for forming high-strength material

December 11, 2007 | By Brett Krause

The demands are increasing for forming with higher-strength work materials, particularly for automotive applications because of their lighter weights. It can be a challenge to find a tool steel material that does not chip, crack, or wear when used on high-strength steels. This article compares various tool steel materials and how they stand up to the challenge.

Choosing between feeding your new stamping line coil or blanks?

December 11, 2007 | By Bruce Bean

Stampers today need to process more grades and types of material than ever before, yet are under relentless pressure to reduce costs. They increasingly rely on systems integrators and equipment suppliers to design and install versatile stamping lines with quick-change capabilities. A notable case was that of a truck frame and chassis components manufacturer. It worked with vendors to develop a line that processes material up to 0.280 in. thick and 72 in. wide, in a range of yield strengths, in three forms – coil, blanks, or sheet.
