Embodiment 1
[0016] Such as Figure 4 A blanking example of pre-rolling a V-shaped ring groove on a bearing steel pipe with a diameter of 31mm, a thickness of 6mm, and a length of 3000mm is shown. The diameter is 200mm, the helix angle β=1.47°, the basic pitch is 16.16mm, and the The length of the rib forming area is 180°, the length of the spiral rib finishing area is 180°, the maximum width of the rib is 2.525mm, and the maximum height is 3.03mm. Bearing steel pipe 1 with a thickness of 31 mm, a thickness of 6 mm, and a length of 3000 mm is pushed into the skew rolling mill as figure 2 As shown, two cross-rolling rolls 1 and 2 with the same pass shape, their axes intersect at an angle of 2.94° in the vertical plane projection of the two rolls, and intersect with the rolling center line at an angle of 1.47°, α=1.47°, two The rotation of the rolls is the same, and the bearing steel pipe 1 rotates in the opposite direction under the action of the rolls, and moves axially along the center ...
Embodiment 2
[0018] Such as Figure 5 An example of pre-rolling a V-shaped ring groove on a round bar of No. 45 steel with a diameter of 41mm and a length of 2000mm is shown. The diameter is 240mm, the helix angle is β=2.3°, and the basic pitch is 30.3mm , the length of the spiral rib forming area is 210°, the length of the spiral rib finishing area is 150°, the maximum width of the rib is 3.03mm, and a pair of rolls with a maximum height of 4.04mm are installed on the skew rolling mill and heated to 1100°C The diameter is 41mm, the length is the 45# steel round bar stock 1 of 2000mm, pushes in the skew rolling mill as figure 2 As shown, two skew rolling rolls 12 and 23 with the same pass shape, their axes intersect at an angle of 4.6° in the vertical plane projection of the two rolls, and intersect with the rolling center line at an angle of 2.3°, α=2.3°, two The rotation of the rolls is the same, and the round bar 1 rotates in the opposite direction under the action of the rolls, and m...
