Description

Movable twist guide apparatus {transfer type twist guide apparatus}

The present invention relates to a guide device for twisting the material of a wire roughing mill, and in particular, a guide roll moves in the direction of the next rolling mill while biting the material to move the twist angle of the material accurately to the next rolling mill guide. A twist guide device.

Conventionally, a material twist (rotation) guide is fixedly installed on a bed of a rolling mill, and an angled roller is fixedly installed in a guide case so that when the material passes through the roller, the material angle is rotated and then proceeds and is inserted into the guide of the next rolling mill. It was a form to become.

In this method, a twist guide fixed to the bed by bolts may be dislodged or inverted by bolt loosening or change the direction of movement of the material.

In addition, even when the twist roller rotation is impossible due to the fixing or breakage of the bearing of the twist roller, it is not found immediately or when used for five days, material defects or product defects occur.

Fixed twist guide is difficult to check and check the guide roll because the quality of the material progress or the quality is determined by the rotational state and the rotation angle of the guide roll.

Such a phenomenon has a problem of deterioration of production and deterioration of quality due to material input and defect.

Accordingly, the present invention was devised to solve the above-mentioned problems, and the object is to accurately move the guide roller for twisting the material together with the roller case while moving the same as the moving speed in the moving direction of the material to accurately insert the material. have.
