水蒸気による加碗であるため、昇温による作業のスピー
ドアップが困難である。In the conventional continuous vulcanization method for unvulcanized rubber and plastic-coated insulated wires, the unvulcanized rubber and plastic insulation coating is extruded onto the conductor and comes out of the extruder, regardless of whether it is rigid or horizontal. The electric wire is introduced into a vulcanizing cylinder connected to an extruder, heated to 150 to 200 oo by high-pressure steam, vulcanized and crosslinked (hereinafter simply referred to as vulcanization), and sent directly to winding through a cooling cylinder. . However, since this method uses water vapor, it is difficult to speed up the work by raising the temperature.

すなわち、下表のように加硫温度の上昇と共に蒸気圧が
急増し、２１１℃では２０ｋ９／泳にもなるので各シー
ル部の気密が保持し驚くなるという欠点がある。That is, as shown in the table below, as the vulcanization temperature rises, the vapor pressure rapidly increases and reaches 20 k9/sw at 211° C., so there is a disadvantage that the airtightness of each seal portion is maintained, which is surprising.

It also has the disadvantage of making things worse.

できる。In order to avoid such disadvantages, various methods that do not use water vapor have been proposed, but these methods have drawbacks such as large-scale equipment or complicated processes that cannot be sped up, so none are yet fully satisfactory. This is the current situation. The present invention was conceived in view of this point, and according to the method of the present invention, the above object can be achieved with relatively simple equipment.

の連続加硫方法である。That is, the present invention coats unvulcanized rubber and plastic-coated insulated wires discharged from an extruder with metal using a metal coating machine installed in the extruder, and then heats and vulcanizes the coating by directly applying a flame to it. This is a continuous vulcanization method for electric wires characterized by removing the metal coating after cooling.

以下これを本発明の実施態様を例示する図面について詳
述する。This will be explained in detail below with reference to the drawings illustrating embodiments of the present invention.

第１図において、心線１は送り出し装置２から押出機３

被覆される。In FIG. 1, the core wire 1 is transferred from the feeding device 2 to the extruder 3
The core wire is then extruded and coated with rubber or plastic insulation.

押出機３には連続金属被覆機４が蓮設されており、押出
機３から出た禾加硫絶縁電線５は、連続金属被覆機４を
通過する間にたとえば鉛層６で被覆される。The extruder 3 is equipped with a continuous metal coating machine 4, and the vulcanized insulated wire 5 coming out of the extruder 3 is coated with, for example, a lead layer 6 while passing through the continuous metal coating machine 4.

鉛層の厚さは電線の外径に応じて調整されるが、たとえ
ば次のようになる。The thickness of the lead layer is adjusted according to the outer diameter of the wire, and for example, as follows.

装置１１に巻取られる。Leaded wire thickness column 76 Approximately 3.7 98 4.0 52.4 2.8 This leaded unvulcanized insulated wire is fed into the heating device 7 using the flame of a gas burner, where the lead is removed. After being directly heated and vulcanized by a flame, the lead layer 6 is stripped off by a peeling machine 10 via a cooling device 8 and a capstan 9, and wound up by a winding device 11.

この方法によれば｛１１カロ硫時に水蒸気を使用しない

分を吸収することがなく、良好な絶縁体が得られる。According to this method, the insulator does not absorb water, and a good insulator is obtained, since water vapor is not used during heating of the 11-carosulfur sulfur, and the insulator is heated with a gas flame through the lead sheath.

〜２７０ｑｏで加硫され、冷却装置８へ送られる。{2} The heating device has a simple structure because there is no need to worry about sealing a heat medium such as water vapor. [3-effect heat source can use propane gas as the heat source, making it easy to control the temperature. {4-The temperature of steam vulcanization is limited to about 220℃ at most, but in this method, temperatures of 250 to 270℃ are possible due to the lead coating, so the heating rate can be doubled or tripled. Excellent effects can be obtained, such as being able to increase the flow rate and shorten the length of the flow tube. FIG. 2 shows an embodiment of the present invention, in which the unvulcanized insulated wire is coated with a lead layer 6 by a continuous lead coating machine 4 in the same way as in FIG. Wrap a single or double layer of metal tape with no wrap (the second tape should be wrapped to cover the seam of the -th tape).
After being wrapped, it was directly exposed to the flame in the heating equipment 7 for 250 yen.
It is vulcanized at ~270 qo and sent to the cooling device 8.

3, the tape is rewound, the lead layer is removed by a peeler 10 via a capstan 9, and the tape is wound onto a winding device 11. Before the wire enters the heating device, the metal tape is sent out from the tape winding machine 12 and wrapped around the wire. I need to put it on.

。In this way, the thermal expansion of the insulator is suppressed by the plating pressure of the metal tape, making it possible to perform vulcanization at a higher temperature, thereby further increasing the effects of the present invention.
