Whether you're using a high-speed stamping press to make simple parts at breakneck speeds or doing something really tricky, like deep drawing a material that puts up a lot of resistance, the information in this technology area is sure to help. The articles, case studies, and press releases cover stamping presses, lubricants, and materials.

Press monitoring systems improve overall equipment effectiveness (OEE) and help identify downtime culprits. Press controls track when the machine is running and when it is not. It counts machine cycles, and can detect both empty strokes and cycles when die protection or tonnage faults exist.

Wiegel Tool Works stamps large, complicated automotive circuitry in high volumes for perfection-demanding applications. The manufacturer needed a fast press with a large bed and adjustable-stroke capabilities. It had a specially designed mechanical press custom-built for its unique needs.
What makes a hydraulic press equipped for hot stamping? Access for auxiliaries and process equipment, a rapid deceleration rate, correct tonnage, and off-center load handling are all considerations.

Quick die change, introduced decades ago, has become a staple of lean manufacturing in most stamping shops. QDC equipment itself is being upgraded and their lines expanded to meet evolving requirements for speed and safety, including force evaluation systems on magnetic die clamping, auto-positioning, auto-clamping, thinner magnetic clamping plates, trackless carts, and automated storage and retrieval systems.

Servo technology has been has been used as the drive system of servo-mechanical presses since 2000. Today stampers need to look at a servo press as part of a manufacturing system rather than just a standalone machine to maximize their cost-saving benefits.

Established and growing Jagemann Stamping Co. recently expanded its facility in the charming Great Lakes coastal town of Manitowoc, Wis., to facilitate its continuous growth. The multicapable manufacturer of deep-drawn, progressive stamped, and fineblanked components drew on its ability to diversify to grow and prosper, reaching $80 million in annual sales and expanding by 50,000 sq. ft. and 130 employees last year.

The tried-and-true approaches that worked well to stamp first-generation steels are not as effective for stamping advanced high-strength steels (AHSS). Tests were conducted to determine optimal punch-to-die clearances, shear angles, and punch angles. Test results indicated that 12 to 15 percent punch-to-die clearances and -15- to +15-degree shear angles provided the longest punch and die life, and a 7-degree conical shear angle created the smallest burr growth.

Excessive press downtime between jobs is stamping’s perennial albatross around the neck. To expose the culprits in your shop, try scrutinizing every step in a coil handling system, from the coil itself to the material pilot guides in the tool.

To realize the importance of a good die preventive maintenance program, all a stamper has to do is recall the last time a press line shut down because of a major die problem. The downtime and reaction of the frustrated customer likely are hard to forget. The associated costs, however, aren’t typically documented. That shouldn’t be the case, because those costs can be very important in trying to convince management that a robust tooling maintenance program is worth every cent invested in it.
Most stampers don’t think twice about running a hydraulic press like it has been run for the last 20 years. By doing so, they are losing out on dramatic cost savings associated with a possible energy-saving retrofit that’s centered around a smart variable-speed pump drive.

: Do you have the right below-the-hook lifting equipment for your material handling needs? Not many metal formers ask themselves that question, but they probably should, especially if they are concerned about eliminating possible coil damage and keeping employees safe.

To stamp out the hidden costs of stamping lubrication, first keep everything consistent. Second, apply it right. Third, don’t forget disposal. And fourth, get lubricant to the press efficiently.
