Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire drawing method for a wire drawing machine for manufacturing an electric wire cable core wire or the like.

[0002]

2. Description of the Related Art A device for manufacturing a cable core wire or the like generally draws a terminal from a rough wire drawn in a coil and guides it through a guide roller to a multi-stage wire drawing machine, A die is installed at the entrance of the die, and the wire drawing that is reduced in diameter by this die is forcibly attracted by the capstan of the wire drawing machine body, and the wire drawing is carried out in stages little by little. After that, when the wire is drawn to a predetermined diameter, the wire is wound around a winder.

Before starting the above-mentioned ordinary wire drawing operation, a device generally called a mouth-knitting machine is provided along with the above-mentioned production line for the case where an initial setting is carried out in advance. At the time of initial setting, pull out the end of the rough line, pass it through the guide roller, and then guide it to the mouthpiece machine. Like the wire drawing machine, the mouthing machine is provided with an arm for attaching a die at the entrance, and the body is equipped with a capstan. The terminal of the core wire is rolled by such a mouthing machine so that it can be passed through a predetermined wire drawing die, and the wire is drawn by the wire drawing die of the mouthing machine as much as it is attached to the capstan of the wire drawing machine.

[0004]

By the way, when a cable core wire or the like is drawn by the above-mentioned wire drawing machine, the rough wire for supply is a wire rod of 9.5 mm or more having a large wire diameter of copper or copper alloy. A wire rod is used which has been subjected to work hardening by peeling or drawing the surface of the wire rod or a wire rod of less than 9.5 mm. Since the wire rod is wound in a coil shape, it has a winding curl, and the wire diameter is large and it is difficult to correct the curling curl manually because it has undergone work hardening. It is very laborious to pass the tip of the wire rod between the groove of the guide roller provided and the bracket supporting the guide roller.

Further, after the wire rod is passed through for wire drawing work, the tip of the wire rod must be pulled up to the mouthing machine so that the wire rod can be passed through the wire drawing dies or capstans of a plurality of wire drawing machines and hooked. It is difficult for one person to perform the pulling work due to the resistance of the guide roller portion due to the winding of the wire rod and the weight of the wire rod, and a large number of workers are required, resulting in poor workability.

[0006] The present invention provides a wire drawing method for a wire drawing machine, in which the rough drawing wire for supply can be easily wired, keeping in mind the current state of the wire drawing method for a conventional wire drawing machine. To do is a technical issue.

[0007]

In order to solve the above problems, the present invention preliminarily cuts a predetermined path length from a supply position of a rough wire for supply to a winding machine through a plurality of stages of wire drawing machines, This rough drawing wire is drawn with a mouthing machine to a diameter that can be drawn in each predetermined section by the wire drawing machine of each stage, and it is passed through the necessary drawing die, and one end of the pre-processed setup drawing wire is supplied. After connecting it to the end of the wire drawing wire, wire the setup wire to each wire drawing machine and insert the openable guide roller provided at the entrance of the wire drawing machine into the roller groove to open the wire. The method of drawing the wire on the wire drawing machine is as follows.
