Description
Technical Field

[0002] The guide is a device installed before and after the roll pass to help the rolled piece enter and exit the roll pass accurately and stably in a predetermined direction and state during the rolling process. In the profile mill, the guide is installed on the mill frame and is located before and after the roll. The guide in front of the roll is used to accurately guide the rolled piece into the roll pass, ensuring that the rolled piece is stably deformed in the roll pass and obtains the required geometric shape and size. The guide behind the roll is used to accurately and stably guide the rolled piece out of the roll pass.
[0003] In a small and medium-sized steel rolling continuous production line, the billet needs to go through many continuous rolling passes before it can be rolled into steel. Before the rolled piece is rolled out from the previous rolling pass and enters the next pass, it needs to be twisted to a set angle, so a twist exit guide device is installed at the exit of the rolling mill. The existing twist exit guide usually achieves the effect of twisting the rolled piece through two twist rollers, but as the use time increases, the surface of the twist roller will gradually wear, so that the distance between the two twist rollers increases, and the existing twist exit guide is not convenient for adjusting the distance between the two twist rollers, which will cause the rolled piece to be twisted out of place, and then the rolled piece cannot be twisted to the set angle, so that the use effect of the twist exit guide is affected.

[0047] When adjusting the distance between the two torsion rollers 6, the operator turns the dial head 8 to drive the bidirectional worm 71 to rotate, thereby driving the two eccentric worm gears 72 to rotate in opposite directions, and then driving the two torsion rollers 6 to move in opposite directions synchronously. Adjusting the distance between the two torsion rollers 6 helps to improve the convenience of adjusting the distance between the two torsion rollers 6, thereby helping to ensure the torsional effect of the two torsion rollers 6 on the rolled piece, and further helping to ensure the effectiveness of the torsion exit guide.
[0048] When the distance between the two torsion rollers 6 is adjusted, the operator presses the toggle block 93, and the positioning block 91 is engaged with the bidirectional worm 71 through the connecting rod 92, so that the positioning block 91 is used to block the rotation of the bidirectional worm 71, which helps to improve the stability of the eccentric worm gear 72 and the torsion roller 6 after the position adjustment, further ensures the torsion effect of the two torsion rollers 6 on the rolled piece, and further ensures the use effect of the torsion outlet guide.

After the rotation of the torsion head 4 is completed, the slotted nut 13 is tightened, and the cotter pin 14 is passed through the slotted nut 13 and the adjusting worm 52 to limit the relative displacement between the slotted nut 13 and the adjusting worm 52, thereby positioning the adjusting worm 52, which helps to improve the stability of the torsion head 4 after the angle is adjusted, thereby helping to ensure the accuracy of the torsion angle of the rolled piece, and further ensuring the use effect of the torsion outlet guide.
