Description

씨브의 화염열처리장치{Flame heat treatment device of sheave}Flame heat treatment device of sheave

본 고안은 씨브(Sheave)의 화염열처리 장치에 관한것으로서 보다 구체적으로는 씨브의 크기에 따라 화염을 분사하는 화염분사장치 및 냉각수 분사장치를 전후 및 승,하강 작동할 수 있게 함으로서 다양한 크기의 씨브를 화염열처리 할수 있게 한 것이다.The present invention relates to a flame heat treatment device of a sheave, and more specifically, to a sieve of various sizes by allowing the flame spraying device and the cooling water spraying device to spray the flame according to the size of the sheave to be able to operate back and forth and down and down. Flame heat treatment.

일반적으로 씨브(Sheave)는 로프풀리를 지칭하는 것으로 콘테이너운반용 크래인 및 타워크래인등에 사용되는 대형의 로프풀리는 고주파 및 저주파 열처리를 통하여 로프풀리의 로프감김부를 열처리하는것이 일반적인 열처리 방법이다.In general, sheave refers to a rope pulley, and a large rope pulley used for a container transport crane and a tower crane is a heat treatment method of a rope winding part of a rope pulley through high frequency and low frequency heat treatment.

그러나 상기와 같이 고주파 및 저주파에 의한 열처리는 급작스런 가열로 인하여 로프풀리의 사용시에 로프권치부의 표면에 박리현상이 발생하게 된다.However, as described above, the heat treatment by the high frequency and the low frequency causes the peeling phenomenon on the surface of the rope winding part due to the sudden heating.

즉 순간적인 가열로 인하여 가열되는 열처리부와 열처리가 되지 않은 소재부에 경계가 발생하게 됨으로서 열처리된 로프풀리가 사용중에 열처리부의 표피층에 박리현상이 발생하게 되는것이다.That is, due to instantaneous heating, boundary between the heated heat treated portion and the unheated material portion is generated so that the peeled phenomenon occurs on the skin layer of the heat treated portion while the heat treated rope pulley is in use.

그리고 상기와 같은 결점을 방지하고 환형의 제품을 화염열처리를 수행하기 위하여 승,하강 작동하며 회전하는 테이블상에 열처리 소재를 장착하여 소재를 회전시키며 가열하고 가열된 소재를 하강시켜 오일등에 잠기게 함으로서 환형의 소재를 화염열처리하는 화염열처리장치가 제안되어 사용되고 있다.In order to prevent the above drawbacks and to perform flame heat treatment of the annular product, the heat treatment material is mounted on the rotating table to move up and down, and the material is rotated and heated and the heated material is lowered to be submerged in oil. A flame heat treatment apparatus for flame heat treating annular materials has been proposed and used.

그러나 상기와 같이되는 화염열처리 장치는 화염방사노즐의 위치조정이 어려워 다양한 크기의 소재를 가공하지 못할뿐만 아니라 가열된 소재를 냉각시에는 소재를 장착한 테이블을 하강시킴으로서 소재의 하단부터 냉각오일등에 잠기게 됨으로 소재의 열처리부 경도가 떨어지게 되는결점이 있었다.However, the flame heat treatment device as described above is difficult to adjust the position of the flame spinning nozzle, so that it is not possible to process materials of various sizes, and when the heated material is cooled, the table equipped with the material is lowered so as to be immersed in the cooling oil from the bottom of the material. As a result, there was a defect that the hardness of the heat treatment portion of the material falls.

본 고안은 상기와 같은 종래의 결점을 개선코자 안출한 것으로서 고주파 및 저주파 열처리방밥에 의하여 발생하는 씨브열처리부의 박리현상을 방지하고 균일한 열처리부를 가질수 있게하여 기계적성질이 우수한 씨브를 얻을수 있도록 하는 씨브화염열처리장치를 제안한 것에 그 목적이 있다.The present invention devised to improve the above-mentioned drawbacks as described above to prevent the peeling phenomenon of the sieve heat treatment caused by the high frequency and low frequency heat treatment and to have a uniform heat treatment to obtain a sieve flame having excellent mechanical properties The purpose of this is to propose a heat treatment apparatus.
