This study illustrated that, when the thickness and stress-strain curve of the sheet material are known, it is possible to predict with acceptable accuracy the bend allowance, springback angle, and punch stroke to obtain the desired final product dimensions.
Spray systems often are regarded as simple on-off valve and regulation systems. In reality, though, spray nozzles are precision components designed to yield very specific performance under specific process conditions. Just because nozzles are spraying doesn't mean that they are spraying precisely, and precision spray performance makes a difference in throughput, quality, and bottom-line profits
When BMW Dingolfing (Germany) decided to modernize one of its transfer presses, the desired benefits included increased line availability, increased production through the use of an electronic transfer system, and reduced maintenance. However, one of its highest priorities was to minimize or eliminate the risk of production loss caused by interruptions to the power supply.
In recent studies, dry-film lubricants have been shown to give better lubrication conditions compared to oil-based liquid lubricants. This factor, as well as savings in the amount of lubricant used, has helped increase the use of dry-film lubricants in the automotive industry for forming of aluminum and high-strength steel stamped parts.
