を、その対象としている。Detailed Description of the Invention (Field of Application and Object of the Invention) The present invention relates to a wire rod coated with a metal such as a required alloy, such as an electrode wire for electrical discharge machining. The metal coating device is equipped with a nozzle filled with molten coating metal, and openings in the upper and lower walls are located on a vertical line, and the metal coating device has a nozzle filled with molten coating metal. The object is a wire that is coated with metal while passing through the opening from below to above.

Unlike the method described above, the wire must pass through the coolant chamber with the coating metal still in liquid form and without touching the packing or any surfaces; It is difficult to maintain this cooling liquid above the metal-filled nozzle.

は噴霧された水を回収しなければならなくなる。 A solution to this problem has already been proposed, such as the method disclosed in US Pat. No. 3,782,326, by spraying a coolant onto the wire in the form of a mist. However, in this cooling method, compared to the case of immersing the body in a liquid tank, even if the size of the area to be cooled is the same, the surface area that is actually cooled is smaller, so the effectiveness is lower. Furthermore, spraying such a liquid may disturb the surface condition of the coated surface that has just been applied and has not yet been cured. In addition, when the coating material is an alloy, there is a considerable range of curing temperatures depending on the composition of the alloy, so this fear becomes even more certain. And finally, this method requires that the sprayed water be recovered.

れる。 In U.S. Pat. No. 3,727,895, the wire passing through the coating metal tank is passed through a cooling device having a cooling chamber with a funnel-shaped bottom.
A method has been proposed in which cooling is performed by sending a cooling liquid tangentially to the wire so that the cooling liquid swirls from top to bottom within the chamber. There is a chamber below it that feeds pressurized gas, and the cooling liquid is discharged from the funnel-shaped bottom of the cooling chamber. In this method, the wire passes through a zone of high velocity gas before entering the cooling chamber, creating turbulence that is noisy and disturbs the surface of the coating.

When cooling the wire rod 2 passing through the chamber 12 from the bottom to the top, the cooling liquid is reliably maintained within the chamber 12 without leaking to the outside from the opening 13 at the bottom, and when the wire rod 2 passes through the chamber 12, Air bubbles sucked into the chamber 12 from the lower opening 13 are deflected from the running path of the wire rod 2 by a deflector 24, allowing the cooling liquid to uniformly and directly touch the wire rod 2. The coating layer of No. 2 is cooled evenly, and in addition it is avoided that the coating layer is disturbed during curing. Furthermore, the coolant in the chamber 12 heated by the metal-covered wire is heat exchanged by the cooling fluid circuit 21 surrounding the chamber 12, and the temperature of the coolant in the chamber 12 is always maintained at an appropriate temperature. .

ることができる。 To make the cooling device described here function, first, a cooling liquid (water) is injected into the chamber 12. At that time, the opening 13 is closed, the valve 18 is opened, and the tip of the conduit 17 is placed in a container storing cooling liquid, so that the height of the cooling liquid is within the chamber 12 and the vertical guide portion 24a of the baffle plate 24 is raised. The vacuum pump 20 is moved until it reaches a level slightly below the upper end. Next, opening 13 is opened and valve 18 is closed. The vacuum pump is kept running so that bubbles continue to be sucked through the opening 13 and the coolant level remains constant. As a result, the inside of the chamber 12 is constantly surrounded by an air layer 12b above the coolant liquid layer 12a.
It will be in a state where it has. In the example, the diameter of the wire 2 is 0.6 mm, while the diameter of the opening 13 is 8 mm.
mm. The rotational speed of the vacuum pump is adjusted so as to minimize the number of bubbles generated and to prevent the still liquid coating metal adhering to the wire rod 2 from being disturbed. The air bubbles sucked in through the opening 13 are obstructed by the inclined guide part 24b of the baffle plate 24, rise obliquely along the inclination, and pass between the vertical guide part 24a and the inner surface of the chamber 12. It reaches the air layer 12b. Therefore, after the wire passes the opening 25 of the inclined guide portion 24b, the wire advances upward in the liquid layer 12a of the coolant without coming into contact with air bubbles, unlike the case where the air bubbles rise along the wire. , it will be cooled evenly and evenly. In addition, the deflection of air bubbles and the absence of rapid flows of the cooling liquid in the chamber 12 avoid disturbing the coating layer during curing.
冷却を行つている間は、チエンバー１２の冷却
液の温度を逃がすように、中空カバー２１内を水

式で求められる。 Assuming that the coolant in chamber 12 is water, and assuming that the heat exchange between the wire and the coolant takes place under optimal conditions, a copper wire with a diameter of 0.6 mm is made of Pb-Sn (alloy of lead and tin). When the coated wire is cooled from 250°C to 50°C, the amount of heat P emitted from the wire is determined by the following formula.
Ｐ（ワツト）＝3.95V（m/mn）

れる。 P (watts) = 3.95V (m/mn) It is assumed that heat exchange is performed under optimal conditions between the water in the chamber 12 and the water in the hollow cover 21, and between the inlet and outlet of the hollow cover 21. , the temperature is 21
℃ to 30℃, the amount of water D that should pass through the hollow cover 21 is determined as follows.
Ｄ（/mn）＝1.2×10-3V（m/mn）
Ｖ＝線材の速度
従つて、最大生産速度である300m/mnでは、
必要な水量は0.56/mnとなる。チエンバー１２
の内部の水の高さは約70cmなので、これは水量と
しては1.5弱となる。 D (/mn) = 1.2 × 10 -3 V (m/mn) V = wire speed Therefore, at the maximum production speed of 300 m/mn,
The required amount of water is 0.56/mn. Chamber 12
The height of the water inside is approximately 70 cm, so this is a little less than 1.5 cm in water volume.

とする線材の金属被覆装置における冷却装置。1 A nozzle filled with molten metal and having openings on the vertical line in the upper and lower walls of the nozzle is provided, and a running wire passes through the openings of the nozzle from below to above. A cooling device for the coated wire in a wire metal device in which the wire is coated with molten metal, which includes an entrance/exit through which the metal-coated wire passes from below to upward while the metal-covered wire is running. a chamber whose upper part is connected to a suction device piping, whose lower part is connected to a cooling liquid supply piping, and whose inside forms a liquid layer of the cooling liquid supplied from the cooling liquid supply piping and an air layer above the liquid layer; Along with deploying
This chamber consists of a vertical guide part and an inclined guide part extending diagonally downward from the lower end of the vertical guide part so as to block the path of the metal-covered wire, and an opening for passing the metal-covered wire is provided in the inclined guide part. A cooling device for a wire metal coating device, characterized in that the chamber is surrounded by a cooling fluid circuit having a deflector and a cooling fluid supply section and a discharge section. .
