제1도는 본 고안의 종단면도임.1 is a longitudinal cross-sectional view of the present invention.

본 고안은 타이어의 성형을 위하여 사용되는 고무시트를 절단하기 위한 칼의 가열장치에 관한 것이다.The present invention relates to a heating device of a knife for cutting a rubber sheet used for molding a tire.

고무시트를 절단함에 있어서는 칼날의 예리함을 필요로함과 동시에 절단칼을 섭씨200동이상으로 가열하여 사용하는 것이 바람직하다.In cutting the rubber sheet, it is desirable to sharpen the blade and to use the cutting knife heated to 200 degrees Celsius or more.

그리하여 종래에는 전열장치에 의하여 가열되는 가열로에 칼집을 형성시키되 칼집의 입구부를 대략 깔대기모양으로 칼의 단면보다 조금 넓게 형성시켜 되도록 칼을 쉽게 끼워 넣을수 있게 하였다.Thus, in the related art, a sheath is formed in a heating furnace heated by a heat transfer device, but the inlet portion of the sheath is approximately funnel-shaped so as to be slightly wider than the cross section of the knife so that the knife can be easily inserted.

그러나, 고무시트를 절단하는 가열된 칼의 열은 대기 및 고무시트에 방열되어 곧 식어버리므로 식은 칼은 가열로의 칼집에 넣고 다시 가열하여 사용하게 된다.However, since the heat of the heated knife for cutting the rubber sheet is radiated to the atmosphere and the rubber sheet to cool down soon, the cooled knife is put into the sheath of the heating furnace and heated again.

이와같이 칼을 반복, 가열하여 사용함에 있어서, 숙련공일수록 신속하고 빈번이 절단용 칼을 인입인출하게 되는데 좁은 칼집에 칼을 넣기가 비교적 수월치 아니하여 예리하여야 할 칼의 선단부가 쉽게 무터지고 전기가열로의 칼집입구부는 파손되게 마련이다.In this way, in the repeated and heating use of the knife, the more skilled artisan draws in and out the cutting knife more quickly and more frequently. It is not easy to put the knife into a narrow sheath, so the tip of the knife to be sharpened is easily broken and the electric heating furnace Sheath entrance is broken.

이와같은 칼날가열장치에 있어서 중요한 것은 절단용칼의 신속정확을 인입 인출을 용이하게 하는데 있다.The important thing in such a blade heating apparatus is to make it easy to draw in and take out the quick accuracy of the cutting knife.

그렇다고 평면으로된 가열장치위에 칼을 던지듯 올려놓는다면 제자리에 있지 못하고 떨어져 내려버티므로 이를 다시 우워서 올려놓는다면 이는 오히려 종래의 가열장치만도 못하게 된다.However, if you throw a knife on a flat heating device, it will not fall into place and will fall off, so if you put it back on it, it will not be possible even with a conventional heating device.

그리하여 가열장치에 자석을 설치하는 방법을 시도하려해도 가열된 영구자석을 그 자성을 쉽게 잃게 되므로 영구자석을 그 자성을 쉽게 잃게 되므로 영구자석을 사용할수도 없고 그렇다고 전자석을 사용하자니 고열에 의해 전자석의 코일이 견딜수도 없게 된다.Thus, even if you try to install a magnet in the heating device, the heated permanent magnet will easily lose its magnetism, so the permanent magnet will easily lose its magnetism, so you will not be able to use permanent magnets. The coil can't withstand it.

이에 본 고안은 영구자석을 사용하더라도 그 자력이 상실되게 아니할수 있는 가열장치를 제공하고자 하는 것이다.The present invention is to provide a heating device that can not be lost even if the permanent magnet is used.

즉, 본 고안은 영구자석의 주위에 전열선을 배하되 전열선이 전자석의 코일과 같이 영구자석의 극방향에 일치하도록 감는다.In other words, the present invention distributes the heating wire around the permanent magnet, but the heating wire is wound so as to coincide with the pole direction of the permanent magnet like a coil of the electromagnet.

그러므로서 전열선으로부터 나오는 자력이 영구자석의 손실자력을 보충할수 있게 하여 장시간 사용할수 있도록 안출된 것으로 이를 첨부된 도면에 의하여 설명하면 다음과 같다.Therefore, the magnetic force coming out of the heating wire was made to be used for a long time to make up for the lost magnetic force of the permanent magnet as described by the accompanying drawings as follows.

영구자석(1)의 외주에 절연층인 1차케이스(2)를 개재시켜 전열선(3)을 권취하되 전열선(3)의 자력선 방향과 영구자석(1)의 자력선방향이 일치되도록 한다.The heating wire (3) is wound around the outer circumference of the permanent magnet (1) by the primary case (2), so that the direction of the magnetic force line of the heating wire (3) and the direction of the magnetic force line of the permanent magnet (1).

이와같은 전열선(3)은 그 권취수가 많으면 많을 수록 자력이 세어질 것이니 제1도에 도시된 바와같이 절연층인 2차 케이스(4)를 개재시켜 2차절연선(5)을 감으며 필요에 따라서는 3차, 4차 전열선(도면에 도시하지 않음)을 감을수도 있다. 2차나 3차 4차 전열선의 자력선방향이 영구자석(1)과 동일해야 함은 물론이다.As the number of turns of the heating wire 3 increases, the magnetic force will be increased. As shown in FIG. 1, the secondary insulation wire 5 is wound through the secondary case 4, which is an insulation layer, as necessary. May wind the third and fourth heating elements (not shown). Of course, the direction of the magnetic lines of the second or third quaternary heating wire should be the same as the permanent magnet (1).

이와같은 본 고안의 저부와 측면부에는 적당한 단열재로로서 외부케이스(6)을 형성시킴이 바람직하며, 영구자석(1)의 중심부에 커다락 입구부를 가진 칼집(7)을 형성시키므로서 열손실을 감소시킬수도 있다.It is preferable to form the outer case 6 in the bottom and side portion of the present invention as a suitable heat insulating material, reducing the heat loss by forming a sheath (7) having a large inlet in the center of the permanent magnet (1) You can also.

그러나 이와같은 가열장치에 있어 다른 열손실을 막는일보다는 작업의 신속성에 더욱 중요한 일이므로 칼집(7)을 형성시키는 것이 바람직한 일만은 아니다.However, in such a heating device, it is not preferable to form the sheath 7 because it is more important for the speed of operation than to prevent other heat loss.

이와같은 본 고안은 가열된 영구자석(1)상면에 칼을 신속히 올려놓더라도 자력으로 인해 저면으로 떨어질 염려가 없으며, 따라서 작업의 신속성을 항상시킬수 있으며 종래와 같은 칼끝의 무디어짐이나 칼집 입구부의 파손을 방지할수 있고, 고열에 의해 손실되는 영구자석(1)의 자력은 전열선(3)에서 발생하는 전자력에 의하여 보중되어 장기간 사용이 가능하게 된다.The present invention, even if the knife is quickly placed on the heated permanent magnet (1), there is no fear of falling to the bottom due to the magnetic force, and thus can always make the speed of work and the blunt of the tip of the knife or damage to the sheath inlet It is possible to prevent, the magnetic force of the permanent magnet (1) that is lost by high heat is interpolated by the electromagnetic force generated in the heating wire (3) can be used for a long time.
