Description

ROLLER ASSEMBLY FOR ROLLING MACHINE FORMING HETEROMORPHIC PROFILE WIRE}

The present invention relates to a roller assembly for a release wire rolling mill, and more particularly, in a release wire rolling mill for rolling a release wire in a cross-sectional profile engraved on a surface of a main body of one roller. A roller assembly for a release wire rod rolling mill having means on the roller housing side that can horizontally match the cross-sectional shape engraved on the roller body surface.

On the surface of the roller body of a rolled wire forming machine for rolling a release wire rod having a constant cross-sectional shape by forming two sets of rollers, grooves having a cross-sectional shape corresponding to the cross-sectional shape of the release wire rod to be molded are partially disposed on the two rollers. It is formed separately.

In order to roll the release wire rod using such a roller assembly, it is necessary to horizontally match the cross-sectional shapes formed on the two roller surfaces. This is because the release wire rod having the desired cross-sectional shape can be rolled.

To this end, conventionally, a thread is formed for each of the shaft portions of the roller, and two lock nuts having opposite directions of movement are filled therein, and then the lock nut side is brought into contact with the inner surface of the roller housing, and the roller By loosening or tightening the lock nut on the left and right axes, the rollers were horizontally moved to match the cross-sectional shapes formed on the surfaces of the two roller bodies.

However, since the horizontal adjusting means of the conventional roller assembly has to thread a part of the rotating shaft of the roller, and the lock nut must be loosened or tightened in a narrow space between the roller body and the inner surface of the roller housing, it is not easy to adjust the horizontal position of the roller. There was a problem.

The present invention has been made to solve the above-mentioned problems of the prior art, the roller assembly of the rolling machine for the release wire rod that can achieve the horizontal position adjustment of the roller by feeding the axis of the roller by a simple operation on the outer surface of the roller housing The purpose is to provide.
