Stamping Articles

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.

10 common quick die change problems

November 7, 2006

By:

Die changeover is one of the few times when a press isn't making money. Why do some die changeovers take hours? It might be the press, operator, die, material, lift truck, crane, or the tools.

R&D Update: Multipoint-control die cushion systems for stamping complex parts - Part II

November 7, 2006

By:

In deep drawing of complex, asymmetrical parts such as stainless steel kitchen sinks, blank holder force (BHF) needs to be controlled locally to regulate the flow of the sheet metal. An MPC blank holder system allows this control by placing individually programmable cushion pins around the blank perimeter, with an appropriate BHF selected at each pin location.

Multipoint-control die cushion systems for stamping complex parts - Part II

October 10, 2006

By:

Editor's Note: This article is Part II of a three-part series that discusses multipoint-control (MPC) die cushion systems applied to the forming of stainless steel double sinks. Part I, which appeared in the September issue, discussed novel press and design concepts using MPC systems. Part III,...

Ask the Stamping Expert: Overcoming deformity by design

October 10, 2006

By:

Achieving typical goals in stamping, such as zero development and fewer labor requirements, is made easier when the progressive die strip is kept level through the entire progression. Keeping the strip level can eliminate wave problems caused by incorrect pilot/lifter use occurring in punch forming.

Drawing on new experiences

October 10, 2006

By:

In the past metal forming in the appliance industry meant giant presses with expensive tooling. Lead-times were forever, and change didn't come easy. Whirlpool Corp. in Fort Smith, Ark., is taking a new approach to metal forming, and flexible technologies are the key.

Die Basics 101: Part X

October 10, 2006

By:

Cutting is the most severe metalworking process that takes place in a die and shouldn't be taken lightly. Cutting Basics Cutting metal requires great force. For example, it takes approximately 78,000 lbs. of pressure to cut a 10-in.-diameter blank from 0.100-in.-thick mild steel. Consequently,...

Transfer technology

October 10, 2006

Venest Industries, an automotive parts supplier based in St. Catharines, Ontario, Canada, needed an automated transfer system that could be parked away from the machine bed during progressive operations and die changes, so that new dies could be delivered to the press via an overhead crane.

Die Science: Setting up progressive dies - Part I

October 3, 2006

By:

Editor's Note: "Setting Up Progressive Dies" is a two-part article. Part I discusses press and die cleanness, die alignment, clamping procedures, and preliminary shut height calibration. Part II discusses the process for getting metal into the die, setting the pitch, feed release, and other factors...

Holding the line on metal costs

September 12, 2006

By:

Stampers and roll formers can look at edge trim, heads, tails, skeletons, and coil damage for ways they can reduce scrap to hold the line on metal costs.

Draw forming, Part IV

September 12, 2006

By:

The relationships among part geometry, tool geometry, and control of the processing inputs are significantly different between the net shape and non-net shape processes.

Doing its level best

September 12, 2006

A precision roller leveler, installed between the coil payoff reel and the press equipment, allows an operator to stretch the edges when necessary to compensate for loose centers or stretch the center to compensate for loose edges before the blanking operation.

Draw forming, Part III

August 8, 2006

By:

The connections between product conditions and product input variables for draw forming must be made through the intermediary transformation characteristics: plastic strains and displacements. So all product requirements must be redefined as the changes (or transformations) required of those two characteristics.

Die Science: Unique forming short cuts

August 8, 2006

By:

Die designers often are faced with how to make a part feature that is unique and possibly difficut to form. Short cuts are discussed for twisting a part, creating a return flange, and making a 90-degree bend.
