Draw forming, especially in the aerospace and medical industries, requires unparalleled accuracy and precision. That’s why, for nearly 50 years, manufacturers have relied on Beckwood’s customizable multi-action deep draw presses and Triform sheet hydroforming presses. Bed size, tonnage, stroke, speed, and more can be tailored to your specific draw-forming application.
During the most common draw forming applications, a punch is mounted on the press bed, and the blank material sits on the draw ring supported by the bed cushion. When the upper tool contacts the blank, the cushion retracts downward, forming the material over the stationary punch. Beckwood’s dynamic cushion control allows for tonnage adjustments throughout the entire draw process, giving the operator complete control over material flow to eliminate wrinkling and tearing.
Triple-action presses are another great option to manufacture large sheet metal parts. A typical triple-action deep draw press consists of a punch or forming tool on the main draw ram, a clamp ram in the middle, and a knockout cylinder and/or bed cushion on the bottom. The clamp ram, which offers individual tonnage control on each cylinder, is engaged throughout the forming process to control material flow and reduce wrinkling and tearing. With this configuration, the lower ram can serve either as a knockout for part ejection or as a cushion, depending on tooling requirements.
