本発明は伸線機により線材を伸線してブライトワイヤー

い。As the iron wire for plating the surface, a so-called bright wire, which has a particularly smooth and glossy surface, is used. In order to manufacture bright wire by drawing a wire with a wire drawing machine, it is necessary to completely remove scale from the surface of the raw material wire. If even a small amount of scale remains on the wire surface before wire drawing, scratches will remain on the wire after wire drawing, making it impossible to obtain a high-quality bright wire.

材を脱スケールする方法を開示している。Furthermore, the present inventor has already disclosed in Utility Model Application Publication No. 55-148811 that in the wire drawing pre-treatment step, the wire rod surface is buffed by bending the wire rod and using a buffing wheel made of a wire brush and a buffing wheel made of a nylon brush. A method for completely descaling wire is disclosed.
上記従来のブライトワイヤーの製造法によれば、線材の
前処理工程で酸洗するため、線材表面にピンホールが発
生し、そのピンホールは伸線工程で消滅せず、最終工程
まで残り、製品のブライトワイヤーの品質が低下する。According to the above-mentioned conventional bright wire manufacturing method, pinholes are generated on the wire surface because the wire is pickled in the pre-treatment process, and the pinholes do not disappear during the wire drawing process and remain until the final process, resulting in the production of products. Brightwire quality is reduced.
更に線材の前処理工程で酸洗して伸線した線材は、保管
中に錆が発生するため、伸線後3〜7日以上保管するこ
とができず、伸線後直ちにメツキ工程等に送る必要があ
る。Furthermore, wire rods that have been pickled and drawn in the pre-treatment process cannot be stored for more than 3 to 7 days after being drawn, as rust will occur during storage, and the wire rods should be sent to the plating process immediately after drawing. There is a need.
又従来のブライトワイヤーの製造法では、伸線速度が遅
く、生産性が低いという欠点もある。Furthermore, the conventional bright wire manufacturing method has the disadvantage that the wire drawing speed is slow and productivity is low.
従って、本発明はピンホールがなく、保存中に錆が発生

目的は伸線速度を速くすることができるブライトワイヤ
ーの製造法を提供することを目的とする。Therefore, an object of the present invention is to provide a method for manufacturing bright wire that does not have pinholes, does not rust during storage, and can be stored for a long period of time. Another object of the present invention is to provide a bright wire manufacturing method that can increase the wire drawing speed.

するに至った。In order to achieve the above object, the present inventor has conducted intensive research and found that the occurrence of pinholes can be prevented by mechanically descaling the wire rod without pickling in the pre-treatment process of the wire rod before wire drawing. In addition, it was discovered that the drawn bright wire does not rust even when stored for a long period of time.
The wire drawing process using the die in the previous stage is lubricated with a vegetable solid lubricant, and by passing the wire through water before entering the die in the final stage, a bright wire with an extremely smooth surface can be obtained.
They have also discovered that the wire drawing speed can be increased, and have completed the present invention.

According to the known method disclosed in the above issue, when the wire is run while being bent in various directions by bending rollers arranged facing each direction, most of the brittle primary scale on the surface of the wire is peeled off and falls off. Next, when the wire is slid and run through a buffing wheel made of a rotating wire brush and a buffing wheel made of a nylon brush containing an abrasive, the secondary scale firmly attached to the surface of the wire is completely removed.

It is divided into two chambers, and an antechamber 00) is provided further forward of the antechamber (4). Preliminary wire drawing die 01 is installed at the rear end of the pre-drawing chamber 00).
), and a known solid powder lubricant α for wire drawing is placed in the pre-chamber (10). After passing the wire through the solid powder lubricant in the pre-drawing chamber 00), the wire is pre-drawn using a pre-drawing die 0υ, and then the wire is drawn through the first-stage die (6) and the final-stage die (7).
The wire is drawn to an appropriate wire diameter that can be drawn to the desired wire diameter using one die. In the case of FIG. 2, the preferable area reduction rate of the final stage die (7) is the same as in the case of FIG. In Figure 2, the wire is passed through three dies in succession,
The pre-drawing chamber α and the pre-chamber (4) are separated by 5 minutes, and a wire winding drum is placed between them, and the wire (2) passed through the preliminary wire drawing die aυ is wound around the wire winding drum. After releasing the tension, the wire (2) may be introduced into the front chamber (4).

つ必要がある。In the above explanation of the case where the wire rod (2) is pre-drawn before being introduced into the front chamber (4), the process of passing the wire rod (2) through a known solid powder lubricant 0 and the step of passing the wire rod (2) through a pre-drawing die αυ are explained. We have explained the case where the wire is passed through the preliminary wire drawing process only once. Then, the wire is passed through the preliminary wire drawing process any number of times, consisting of the process of passing it through the above-mentioned known solid powder lubricant and the process of passing it through a preliminary wire drawing die, and then passed through the first stage die (6) and the final stage die (7). ) can be used to pre-draw the wire to a thickness that allows the wire to be drawn to the desired wire diameter. In this case, while the wire is passed through the preliminary wire drawing process multiple times, it is necessary to pass the wire through a wire winding drum as appropriate to maintain the tension of the wire at an appropriate level during the process.

る。According to the bright wire manufacturing method of the present invention, the mechanically descaled and dried wire rod whose surface is thinly coated with a water-soluble lubricant is predrawn as necessary, and then placed in a die box (1). In the front chamber (4) of the die, it passes through a powdered lubricant (8) made of saponified vegetable oil, etc., and the powdered lubricant (8) is attached to the surface of the powdered lubricant (8). The wire passes through the wire while being lubricated with the lubricant, and undergoes the first stage wire drawing action.
