Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a round bar straightening machine in which oil used for the purpose of cooling the rolls and preventing seizure between the material being straightened and the rolls remains attached to the straightening material. This relates to an oil draining device that prevents oil from being sent to the extraction table.

BACKGROUND ART Conventionally, in a round bar straightening machine, the oil used for the above purpose is sent to an extraction table with the straightening material attached to it, and the straightening material is rotated by passing between the straightening rolls of the straightening machine. Oil splashes on and around the extraction table on the exit side of the round bar straightening machine, leaving it covered in oil. In order to prevent this, some machines are equipped with an air wiper on the exit side of the round bar straightening machine to blow off the oil adhering to the advancing straightening material with air.

Problems to be Solved by the Invention The above-mentioned conventional device uses an air wiper to remove oil attached to the straightening material, and the air is blown backwards in the opposite direction to the direction of movement of the straightening material.
The oil tends to blow off to one side, which not only tends to cause oil pools, but also scatters around due to the rotation of the straightening material and the force of the air, making it difficult to clean as the area around the extraction table becomes stained with oil. There were problems such as the fact that it was not possible to completely remove the oil adhering to the surface.

The present invention was created in view of the above circumstances.

Means for Solving the Problems The present invention solves the above problems, and includes:
The contents will be explained below using FIGS. 1 to 3 corresponding to the embodiment.
