Reshaping method for producing an internal high-pressure reshaping part inserts the internal high-pressure reshaping part into an internal high-pressure reshaping tool while impinging it with internal high pressure after sealing

摘要

An internal high-pressure reshaping part (10) is inserted into an internal high-pressure reshaping tool (12) and impinged with internal high pressure after sealing an assigned end area (15). Fitted on the internal high-pressure reshaping part on an outer peripheral side, a sleeve (18) has relative movement compared to the internal high-pressure reshaping tool and a contour area (20) is released by this, into which the internal high-pressure reshaping part is reshaped area by area via internal hight pressure. An independent claim is also included for a device for producing an internal high-pressure reshaping part.
