Advanced Sheet Hydroforming

Beckwood Press Company (St. Louis, MO), a manufacturer of advanced hydraulic press solutions and the Triform line of specialty forming presses, offers advanced sheet hydroforming with their Triform 20-10-10BD, 25-10-12BD and 32-10-12BD Deep Draw models that provide:

• Improved Cycle Time. Updates to the pressure containment system significantly improves cycle times while maintaining the same ‘Infinite Life’ structural standards to which every Beckwood / Triform press is manufactured. This ‘block design’ containment strategy has been used for years on smaller 12 in and 16 in Triform Deep Draw presses and Fluid Cell presses.
• Integrated Tool Change: Every BD Deep Draw press comes equipped with a standard, efficient and ergonomic tool change system that greatly reduces changeover times. A cartridge-style chamber is conveyed through the rear opening of the press, presenting the blank holder and punch to the operator. An optional T-table allows the operator to stage a secondary cartridge (including the blank holder and punch) for even faster tool changes. The system also allows the press to quickly convert from a Deep Draw configuration to a Fluid Cell configuration, for shallow forming without the need for a movable punch tool.
• Reduced Footprints: BD presses are configurable, giving the customer options for either a horizontal layout (with the hydraulic power unit positioned to the side of the forming chamber), or a vertical one, which features a crown-mounted HPU. For shops where floor space is a concern, the vertical configuration is significantly smaller than previous models with the equivalent forming area.

BD presses also provide precision pressure and position control with built-in recipe handling capability. The ‘In-Sight’ feature allows the operator to pause and open the chamber, at any point in the cycle, for a visual inspection of the forming process, is also included as standard. These presses are also compatible with existing hydroforming tooling. With many manufacturers now operating outdated hydroforming presses, the seamless accommodation of existing tooling is critical. The repeatable process of BD presses allows shops to reduce set-up times, scrap rates and in-process adjustments.

For example, their 20-10-10BD is a 10,000 psi deep draw sheet hydroforming press that features a 20 in diameter maximum blank size, 10 in draw depth capacity and an integrated tool change system for fast change-over. It can form large parts within a relatively small footprint without altering the facility’s foundation. Featuring sub 30-second cycle times and an efficient quick tool change system, this compact deep draw hydroforming press is the perfect solution for shops looking to increase productivity and maximize efficiency.
