AI Technical Summary
Technical Problem
Existing forming stations for metal circuit boards, particularly aluminum, face challenges in quickly heating the boards while maintaining a constructively simple structure, which often results in longer cycle times and increased complexity.
Method used
A forming station with a heating device featuring a hydraulically adjustable 1st heating plate and a 2nd heating plate connected to a hydraulic clamping device, allowing for synchronous adjustment of the heating and forming devices to achieve quick and even heating of the metal circuit board.
Benefits of technology
The forming station enables rapid heating of metal circuit boards with a high contact pressure, achieving a heating rate of at least 100°C/s, which reduces cycle time and maintains a simple structural design.

Abstract
A forming station (1) for hot forming a blank (P) made of metal, comprising a heating device (10), which has a first hotplate (11), which is hydraulically adjustable, and a second hotplate (12), which is connected to a counterbearing (31), wherein the first hotplate (11) and the second hotplate (12) are adjustable relative to one another between an open position, in which they are mutually spaced apart such that the blank (P) can be inserted into or removed from an intermediate space (18) formed between the hotplates (11, 12), and a closed position, in which the blank (P) is clamped between the hotplates (11, 12), and comprising a forming device (20), which has a first die part (21) and a second die part (22), which for the purpose of forming the blank (P) are adjustable relative to one another between an open position and a closed position, wherein the heating device (10) and the forming device (20) are provided with a common adjusting device (30), which synchronously adjusts the first hotplate (11) of the heating device (10) and the first die part (21) of the forming device (20), in that the heating device (10) and the forming device (20) have a common slide (32), which bears the first hotplate (11) and the first die part (21) and is adjustable by means of the adjusting device (30), and in that the second hotplate (12) is mounted on a hydraulic clamping device (25), which has a multiplicity of hydraulic piston-cylinder units (26), with which the second hotplate (12) can be directly or indirectly clamped against the first hotplate (11).
