Description

허브 리덕션의 수중 고주파 열처리 자동화 장치 {INDUCTION HEAT TREATMENT APPARTUS IN THE WATER FOR HUB REDUCTION}Hub reduction's underwater induction heat treatment automation device {INDUCTION HEAT TREATMENT APPARTUS IN THE WATER FOR HUB REDUCTION}

본 발명은 허브 리덕션의 수중 고주파 열처리 자동화 장치에 관한 것으로, 더욱 상세하게는 차량 감속장치 부품인 허브 리덕션이 고주파 열처리되는 공정을 자동화한 장치에 관한 것이다. The present invention relates to an apparatus for automating in-water induction heat treatment of hub reduction, and more particularly, to an apparatus for automating a process in which hub reduction, which is a component of a vehicle speed reducer, is subjected to induction heat treatment.

세계적으로 탄소 배출규제 및 연비 규제가 강화됨에 따라 자동차 완성업체는 연비를 높이기 위하여 부품을 경량화 및 소형화하고, 경량화 및 소형화 된 부품이 종전 부품의 기능을 담당하기 위하여 부품의 품질고급화, 정밀화, 안정화를 요구하고 있다.As carbon emission regulations and fuel economy regulations are tightened around the world, automobile manufacturers are making parts lighter and smaller in order to increase fuel efficiency. are demanding

이에 따라 부품의 표면강도, 내마모성, 내피로성, 내구성, 표면 경도 등을 향상시키기 위해 부품들은 고주파 열처리 과정을 거치게 된다. Accordingly, in order to improve the surface strength, abrasion resistance, fatigue resistance, durability, and surface hardness of the parts, the parts are subjected to induction heat treatment.

이러한 부품 중 하나로서, 허브 리덕션이란, 주로 차량의 휠 허브에 들어가는 허브 리덕션 장치(감속장치)의 부품이며, 이러한 허브 리덕션의 내면에 형성된 스플라인과 외면에 형성된 스플라인에는 고주파 열처리가 되어 허브 리덕션의 품질을 향상시키게 된다.As one of these parts, hub reduction is a part of a hub reduction device (reduction device) that is mainly entered into a wheel hub of a vehicle, and the splines formed on the inner surface and the outer surface of the hub reduction are subjected to high frequency heat treatment to improve the quality of the hub reduction. will improve

그러나, 종래에는 작업자가 수작업으로 대기중에서 피가공물인 허브 리덕션의 내면을 고주파열처리한 뒤, 외면을 고주파 열처리하는 별도의 공정을 수행하는 바, 작업자가 두차례에 걸쳐서 수작업으로 피가공물을 고주파 열처리 장치에 투입, 취출하는 등 작업의 효율성 및 경제성이 떨어진다는 문제점이 있었다.However, in the prior art, an operator manually induction heats the inner surface of the hub reduction, which is a workpiece in the air, and then performs a separate process of induction heat treatment on the outer surface. There was a problem in that the efficiency and economic feasibility of the operation such as putting in and taking out were lowered.

특히, 허브 리덕션은, 일부구간만이 고주파 열처리되어져야하는 제품이므로 동일제품을 동일조건으로 고주파 열처리하더라도 작업자의 숙련도에 따라 피가공물의 품질이 달라져 품질편차가 발생한다는 문제점이 있었다.In particular, since hub reduction is a product that has to be subjected to induction heat treatment only in some sections, even if the same product is subjected to induction heat treatment under the same conditions, the quality of the workpiece varies depending on the skill of the operator, resulting in quality deviation.

또한, 대기 중에서 고주파열처리를 하여 소재자체에 다공성이 크고, 균일 냉각이 어려워 고주파 열처리 부의 균열 발생률이 매우 높다는 문제점이 있었다. In addition, there were problems in that the high porosity of the material itself was high by induction heat treatment in the atmosphere, and it was difficult to uniformly cool, so the crack generation rate in the induction heat treatment part was very high.
