Elevated temperature forming die apparatus
Abstract
An elevated temperature forming die apparatus comprising a lower die part having a first upper surface positioned to engage a lower surface of a first region of such a workpiece, an upper die part supported for reciprocal motion relative to the lower die part, the upper die part having a lower surface that engages an upper surface of a second region of a sheet material workpiece, heaters in thermal communication with the die parts, and a third die part having an upper surface that engages a lower surface of the second region of a sheet material workpiece whose first portion is positioned between the upper and lower die parts, the third die part being supported for reciprocal motion relative to the upper die part such that closure of the upper die part along the first stroke portion against the third die part will clamp the first portion of the workpiece between the upper and third die parts, and the third die part being supported for reciprocal motion relative to the lower die part such that, once the first portion of a workpiece has been clamped between the upper and third die parts a draw region of the workpiece extending adjacentmore »
