Apparatus for automatic length indication for steel wire}

The present invention relates to an apparatus for automatically displaying the unit length for the wire drawn continuously from the drawing machine, and more particularly, by installing a gear-shaped movable mold and a fixed mold on the wire movement path in front of the winder. The present invention relates to a wire automatic display device for automatically displaying the mark without stopping the drawing equipment by providing the zigzag curved display portion to the wire being transported by driving the movable mold at every unit length.

In general, the process of manufacturing galvanized stranded wire is performed after pretreatment such as surface scale removal on the material wire rod, and then drawn through a multi-stage drawing die to reach a predetermined wire diameter using a drawing machine. It consists of the process of obtaining a galvanized stranded wire by using a galvanized wire obtained by galvanizing the surface of a wire by using a strand.

On the other hand, the wire wire wound in the coil form in the winding bobbin through the drawing process is unwound from the bobbin to be wound on a separate plated wire supply bobbin for performing the plating process as a subsequent process, at this time, the bobbin plate for supplying the plated wire The length of the wire drawn on the wire is usually wound by a predetermined length (hereinafter referred to as "unit length").

Accordingly, in the drawing step, the unit length is displayed for the wire wire wound on the winding bobbin, so that the length of the wire is checked through the unit length indicating part during the transition to the subsequent plating process, and the required length is wound on the bobbin for supplying the plated wire. I can do it.

In the process of displaying the unit length of the wire drawn in the wire drawing step of the conventional wire, the length of the wire on the counter display unit indicating the current length of the wire drawn through the wire die is checked and the value is determined. At the time when the length of the wire drawing device is stopped, the process of repeatedly forming the zigzag curved display part by using a separate tool for marking display on the wire and restarting the device is performed.

Therefore, in the conventional display method for the drawing wire, the operator checks the current length of the wire displayed on the counter from time to time, stops the drawing equipment according to the checked length, and displays the marking by manual operation, and then restarts the facility. Due to this, the number of fresh machines that can be covered by a worker is limited, and the worker must always monitor the counter, and the labor intensity increases as a result of manual indication. In addition to lowering the productivity, there is a problem that the productivity of the wire product is lowered due to the intermittent operation of the device.

Therefore, the present invention has been developed as a technical problem to be solved the above-mentioned problems, which are pointed out in the conventional display method of displaying the unit length manually with respect to the drawn wire drawn when the wire of the conventional galvanized stranded wire is drawn.
