Retrofitting a prog-die press for transfer operations

May 13, 2008

By:

Converting 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.

Progressive die strips

Reading progressive die strips — Part I

May 1, 2008

By:

Looking at the results of a process—in this case, the strip produced in the die—certainly can lead to good data indicating the root cause of a problem. Distorted, elongated pilot holes, mismatched cuts are common defects. Distorted pilot holes can be the result of a poor carrier design. An improperly set up feed release can cause misfeeds, pilot hole elongation, and bent, broken, or galled pilots, as well as poor part location and gauging.

Sensor driven errorproofing

Where sensors make sense

April 15, 2008

By:

Sensor-driven errorproofing can help metal stamping shops prevent the production of bad parts. In addition, it can save tens of thousands of dollars in lost production due to crashed dies and downtime. How? Sensors detect the presence of metal—as material being fed into the press, being positioned, or ejected from the press as a stamped part or slug.

Coil automation

Rolling to market - Part II

April 15, 2008

By:

A variety of methods help push a roll forming operation's efficiency. Various coil handling methods offer different levels of efficiency and automation, each suiting certain applications. The key is to analyze an operation, calculate the time spent handling coil, and then determine the best level of coil handling automation to fit.

Sensors clear the way for high-speed stamping

April 15, 2008

By:

When you stamp 100 million automotive parts annually, as does Tennessee Stampings LLC, Portland, Tenn., you might accept die collisions as just part of the "traffic statistics." Not so. Before the dies ever hit the high-speed presses, they are properly sensored to prevent downtime, accelerate production.

Lubrication and galling in stamping of galvanized AHSS

April 15, 2008

By:

Forming of galvanized AHSS involves higher contact pressures at the tool-workpiece interface compared to forming mild steel. Under these severe interface conditions, improper selection of lubricants, tool materials and tool coatings may result in high scrap rates and galling in stamping production.. Based on SDT results, polymer-based lubricant with EP additives and water-soluble DFL were found to be most effective, Synthetic lubricants showed also reasonably small frictional responses with a PVD coated die in forming GA coated strips.

Successful Extruding: Part II

April 15, 2008

By:

Die design and building is a critical part of a successful extrusion process. ironing—vertically squeezing the metal between the punch and the die to increase the surface area—helps refine the extruding process, as does preforming.

Successful Extruding: Part I

March 15, 2008

By:

Extrusion is the process in which a continuous radial stretch flange is created by expanding a hole. Of all of the factors controlling the success of an extruding operation, material type and its mechanical properties are the most influential. Materials exhibiting good stretch capability and stretch distribution characteristics are best suited for extruding.
