| 摘要 |
<p>The invention concerns a device and a method for continuous pressing of a plastically deformable blank (15) into a three-dimensional section with a predetermined cross-sectional area, comprising a substantially cylindrical, fixed die (10), an opening (11) formed in the die, through which the plastic blank (15) is intended to be pressed, and at least one rotary die (12) arranged adjacent to the opening (11), the rotary die having one or more recesses in its peripheral surface for forming the blank, during the rotation of the die, into at three-dimensional section with transverse sectional parts. According to the invention, the rotary die (12) has a varying pitch radius as measured from the axis (C), which allows pressing of sections with varying cross section.</p> |
