Beckwood to Build 3500-Ton Bulge Forming Press for Wabash National

Wednesday, June 5, 2019
Beckwood Press Company, a St. Louis-based manufacturer of hydraulic and servo-electric presses and automation systems, has announced a contract by Wabash National Corporation to engineer and build a custom 3500-ton hydraulic bulge forming press. Scheduled for delivery in October 2019, this machine will form stainless steel and aluminum tank heads with diameters up to 156-in. for Wabash National’s tank and silo business.

The 3500 ton, 285-in. x 216-in. press will weigh approximately 650,000 lb. and be installed in a 6-ft. deep pit. The 160-in.-by-160-in. bolsters will contain machined t-slots for use with the Quick Die Change system, and a fully adjustable 8-point square gib-guidance system will ensure bed-to-ram parallelism throughout the stroke.

To accommodate Wabash National’s existing tooling, the press will be able to bulge form using either air (pneumatic) or water (hydro). Beckwood will design a specialized closed loop pneumatic control system for the bulge forming operation, allowing Wabash National to form parts to specific dome heights while utilizing up to 750psi of air pressure. For fast die changeover: an automated quick-die-change system with chain-driven die clamps and a bed trolley, capable of transporting dies up to 30,000 lb. across a 30-ft track via a push-button controls station. For added safety: polycarbonate guarding around the working area, hydraulically actuated die safety blocks for securing the ram during die changeover, and a collision detection system on each end of the trolley.
