  • a centering pin 4 is in the middle on the end face 2 arranged. It is used for guidance and centering of the blank 6 or the workpiece on the mold 1.
  • the end face 2 has a tooth-like Contour 5 or roughening that the centering pin 4th surrounds and lies within the spur toothing 3. This Contour 5 serves to prevent the blank 6 from rotating or of the workpiece so that it rotates with the molding tool 1 can be connected.
  • the pressure rolling device 100 has also a rotatable mold 101 with a End face 102 on which a tooth structure 103 and a centering pin 104 are attached. On his The centering pin 104 has longitudinal grooves 105 or similar roughening. A blank is over the centering pin 104 on the end face 102 of the Molded 101 pushed. The edge of the central Opening of the blank or workpiece 106 is complementary to the longitudinal grooves 105 of the centering pin 104 designed so that the two parts as anti-rotation interlock.
  • the tooth structure 103 of the Molding tool 101 can therefore be radial from the circumference extend to the centering pin 104.
  • the illustrated Tooth structure 103 is only in the radial direction trained in sections.
  • the axis of rotation 107A of the Press roller 107 extends at an angle ⁇ to that Rotation axis 101A of the mold 101.
  • the angle ⁇ and the peripheral surfaces of the pressure roller 107 are selected that the pressure rollers 107 before the start of the forming up can be moved to the centering pin 104 and that the pressure rollers 107 exert an axial force on the Apply workpiece 106 located on the end face 102 can.
  • the angle ⁇ is at least 10 °, preferably 45 °.
  • the molding tool rotates during the pressure rolling operation 101 and the pressure rollers 107 about their respective axes of rotation 101A and 107A.
  • the pressure rolling takes place from the inside to the outside, i.e. that the pressure rollers 107, which at Stand at the centering pin 104, be moved outwards.
  • the pinch rollers 107 are not moved exactly radially outwards, but under an angle ⁇ so that the direction of advance of the spinning rollers 107 is inclined towards the end face 102.
  • the pressure rollers 107 With increasing radial distance to the axis of rotation 101A of the Forming tool, the pressure rollers 107 are thus closer to the face 102 brought up. This ensures that the pressure rollers 107 the material of the workpiece 106 press completely into the tooth structure 103.
