Upgrade transfer systems’ controls, drives, and bearings without complete replacement with a refurbishment. An appliance-maker had new rail connections, new wireless electrical connection methods for part tracking, electronic torque monitoring, and new kinetics drives installed as part of its press modernization program at 75 percent of the cost of new transfers.

Like so many automotive suppliers, the GT Technologies stamping team encountered tooling challenges when it shifted its work material from cold-rolled steel to a tougher steel for certain components. Its tooling started wearing out in a third of the time, creating downtime havoc and production disruption. Switching to a different tool coating helped the manufacturer resolve its tool and die wear problems.

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.

Stamping manufacturer A.J. Rose, Avon, Ohio, supplies precision-formed, deep drawn, metal products and assemblies such as transmission pistons, torque converter components, impellers, engine timing rings, ABS, water pump components, accessory drive pulleys, AC compressor clutch components, and numerous other powertrain components. The stamper needed the transfer system for a new transfer press to be robust and rigid to minimize tooling bar deflection and vibration. In addition, the system had to be compatible with existing tooling and to integrate well with a servo press’s variable speeds and modes

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.

The evolution of precision blanking began with the shear, moved to the press, and now to the laser. Each type of blanking technology, from cut-to-length lines or blanking on a traditional mechanical press to blanking with servo press technology and laser blanking, comes with its own best applications, advantages, and disadvantages.
