Description
본 발명은 고주파 열처리 장치에 관한 것으로서, 보다 상세하게는 고주파 열처리 장치의 작업대에 작업할 단조품 하부를 구속하는 구속수단을 형성하여 고주파 열처리 작업시 단조품의 하부가 상부보다 벌어지는 것을 방지해주는 고주파 열처리 장치에 관한 것이다.The present invention relates to a high frequency heat treatment apparatus, and more particularly, to a high frequency heat treatment apparatus for forming a restraining means for restraining the lower part of a forged product to be worked on a workbench of the high frequency heat treatment apparatus to prevent the lower part of the forged product from being wider than the upper part during the high frequency heat treatment operation. It is about.
일반적으로 열처리란, 금속 또는 합금에 요구되는 성질, 즉 강도, 경도, 내마모성, 내충격성, 작업성, 자성 등의 제반 성능을 부여하기 위한 목적으로 가열과 냉각의 조작을 여러 가지로 조합시키는 기술이다. 따라서 높은 안정성을 요하는 자동차의 주요 부품들은 열처리 과정을 거치고 있다.In general, heat treatment is a technique combining various operations of heating and cooling for the purpose of imparting various properties such as strength, hardness, abrasion resistance, impact resistance, workability, and magnetic properties required for a metal or alloy. . Therefore, the major parts of the automobile that require high stability are undergoing a heat treatment process.
도 1은 종래의 고주파 열처리 장치를 도시한 단면도이다.1 is a cross-sectional view showing a conventional high frequency heat treatment apparatus.
도 1을 참조하면, 중심에 소정크기의 구멍이 형성된 작업대(20')와, 상기 작업대(20')의 구멍으로 소정높이 돌출된 고주파 열처리 수단(30')으로 이루어진다. 상기 작업대(20')의 중심에 형성된 홀에서 돌출된 고주파 열처리 수단(30')을 중심으로 그 위에 작업할 단조품(10')을 캡형태로 뒤짚어 놓고 고주파 열처리 작업을 시작한다. 고주파 열처리 수단(30')은 작업할 단조품의 내부의 공간에서부터 작업을 시작한다.Referring to FIG. 1, a work table 20 ′ having a predetermined size hole is formed at a center thereof, and high frequency heat treatment means 30 ′ protruding a predetermined height into a hole of the work table 20 ′. The high frequency heat treatment means 30 'protrudes from the hole formed at the center of the work table 20' and the forged product 10 'to be worked thereon is inverted in the form of a cap and the high frequency heat treatment operation is started. The high frequency heat treatment means 30 'starts working from the space inside the forging to be worked on.
그러나, 이와 같은 종래의 구조의 경우 제품의 형상 및 단조시 잔류응력에 의해 단조품의 하부(R2)가 상부(R1)에 비해 더 벌어지는 테이퍼가 발생하게 된다. 이렇게 발생한 테이퍼로 인해 최종 조립품에서 조인트의 유격이 심해지기 때문에 상기 단조품이 장착된 자동차 구동시 소음이 발생하게 되는 문제점 등이 있다.However, in the case of such a conventional structure, a taper in which the lower portion R2 of the forged product is wider than the upper portion R1 is generated due to the shape of the product and the residual stress during forging. Due to the taper generated in this way, there is a problem in that noise is generated when driving the vehicle mounted with the forged product because the clearance of the joint is increased in the final assembly.
본 발명은 상술한 종래의 문제점을 극복하기 위한 것으로서, 고주파 열처리 장치의 작업대에 작업할 단조품 하부를 구속하는 구속수단을 형성하여 고주파 열처리 작업시 단조품의 하부가 상부보다 벌어지는 것을 방지해주는 고주파 열처리 장치를 제공하는데 있다.The present invention is to overcome the above-mentioned conventional problems, to form a restraining means for restraining the lower part of the forging to work on the workbench of the high-frequency heat treatment apparatus to prevent the lower part of the forging from opening than the upper during the high-frequency heat treatment operation To provide.
이러한 목적을 달성하기 위한 본 발명은 평평한 면이고 중앙에 소정크기의 홀이 형성되어 그 중앙에 작업할 단조품을 올려놓도록 하는 작업대와; 상기 작업대에 형성된 홀을 통해 삽입되어 작업할 단조품의 내부를 고주파 열처리하는 고주파 열처리 수단과; 상기 작업대의 윗면 중앙에 형성된 홀의 둘레에서 소정거리 떨어져 위치하는 동시에, 소정높이를 가져 작업할 단조품의 외측 하부를 감싸 고정시키는 구속수단으로 이루어지는 것을 특징으로 한다.The present invention for achieving this object is a flat surface and a predetermined size of the hole is formed in the center worktable for placing the forging to work in the center; High frequency heat treatment means for high frequency heat treatment of the inside of the forged product to be inserted and worked through the hole formed in the work table; Located at a predetermined distance away from the periphery of the hole formed in the center of the upper surface of the workbench, characterized in that it consists of restraining means for wrapping and fixing the outer lower portion of the forging to work with a predetermined height.
이하, 본 발명에 따른 바람직한 일실시예를 첨부도면을 참조하여 상세히 설명한다. 도 2는 본 발명의 일실시예에 따른 고주파 열처리 장치를 도시한 단면도이다.Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings. 2 is a cross-sectional view showing a high frequency heat treatment apparatus according to an embodiment of the present invention.
본 발명에 따른 고주파 열처리 장치는 도 2에 도시한 바와 같이, 평평한 면이고 중앙에 소정크기의 홀이 형성되어 그 중앙에 작업할 등속조인트용 TJ 또는 DOJ 외륜 단조품(10)을 올려놓도록 하는 작업대(20)와; 상기 작업대(20)에 형성된 홀을 통해 삽입되어 작업할 단조품(10)의 내부를 고주파 열처리하는 고주파 열처리 코일(30)과; 상기 작업대(20)의 윗면 중앙에 형성된 홀의 둘레에서 소정거리 떨어져 위치하여 형성되는 동시에, 소정높이를 가져 작업할 단조품의 외측 하부를 감싸 고정시키는 구속틀(23)로 이루어진다.High frequency heat treatment apparatus according to the present invention, as shown in Figure 2, a flat surface and a hole of a predetermined size is formed in the center worktable for placing the TJ or DOJ outer ring forging 10 for the constant velocity joint to work in the center 20; A high frequency heat treatment coil 30 for high frequency heat treatment of the inside of the forged product 10 to be inserted and worked through the hole formed in the work table 20; Consisting frame 23 is formed at a predetermined distance away from the periphery of the hole formed in the center of the upper surface of the work table 20, and wrapped around the outer lower portion of the forging to be worked with a predetermined height.
상기 작업대(20)는 중앙의 홀의 크기가 고주파 열처리 코일(30)이 삽입될 정도의 크기인 동시에, 작업할 단조품(10)의 하부의 직경보다 작게 형성되어 단조품(10)이 안정하게 놓일수 있도록 한다.The worktable 20 is formed such that the size of the hole in the center is large enough to insert the high frequency heat treatment coil 30 and smaller than the diameter of the lower part of the forged product 10 to be worked so that the forged product 10 can be stably placed. do.
상기 고주파 열처리 코일(30)은 열처리용 코일이 형성된 소정 길이의 봉이 상기 작업대(20)를 관통하여 작업할 단조품(10)의 내부의 공간에 위치되어 단조품(10)을 열처리 한다.The high frequency heat treatment coil 30 is a rod of a predetermined length in which a heat treatment coil is formed is located in the space of the forging product 10 to work through the work table 20 to heat-treat the forging product 10.
상기 구속틀(23)은 상기 작업대(20)의 홀의 외측에 일체로 돌출되어 형성된다.The restraint frame 23 is integrally formed to protrude to the outside of the hole of the work table 20.
상기한 구성에 의한, 본 발명의 일실시예에 따른 고주파 열처리 장치의 작용은 다음과 같다.By the above configuration, the operation of the high frequency heat treatment apparatus according to an embodiment of the present invention is as follows.
상기한 도 2를 참조하면, 상기 고주파 열처리 코일(30)이 상기 작업대(20)의 중앙 홀에 삽입되고 작업할 단조품(10)을 상기 열처리 코일(30)을 중심으로 작업대(20)의 상부에 올려 놓는다. 이때 작업할 단조품(10)은 외측 하부가 상기 작업대(20)에 형성된 구속틀(23)의 내주면과 밀착 고정되고 열처리 코일(30)에 의해 열처리 과정을 거치게 된다. Referring to FIG. 2, the high frequency heat treatment coil 30 is inserted into the central hole of the work table 20, and the forged product 10 to be worked on the top of the work table 20 about the heat treatment coil 30. Put it up. At this time, the forging 10 to be worked is fixed to the inner circumferential surface of the restraint frame 23 formed on the workbench 20 and the outer lower portion is subjected to a heat treatment process by the heat treatment coil 30.
따라서, 열처리 과정에서 단조품(10)은 내부로부터 열을 받아 팽창하게 되지만 외측 하부가 구속틀(23)에 의해 구속되기 때문에 하부가 팽창이 최소화되어 단조품(10)의 상부와 하부의 내경의 차이가 거의 없어지게 된다.Therefore, in the heat treatment process, the forged product 10 receives heat from the inside and expands, but since the lower part of the outer part is constrained by the restraint frame 23, the lower part thereof is minimized and the difference between the inner diameter of the upper part and the lower part of the forged product 10 is increased. Almost disappeared.
한편, 본 발명은 상기의 일실시예에 한정되지 않고, 상기의 단조품(10)과 유사한 구조를 가지는 것의 경우 상기 구속틀(23)의 내부 직경을 변경함으로써 적용 가능할 것이다.On the other hand, the present invention is not limited to the above embodiment, in the case of having a structure similar to the forging 10 of the above will be applicable by changing the inner diameter of the restraint frame 23.
본 발명은 상술한 종래의 문제점을 극복하기 위한 것으로서, 고주파 열처리 장치의 작업대에 작업할 단조품 하부를 구속하는 구속수단을 형성하여 고주파 열처리 작업시 단조품의 하부가 상부보다 벌어지는 것을 방지함으로써 단조품의 품질을 안정시키는 효과가 있고 최종 조립품에서 조인트의 유격이 없어져 상기 단조품이 장착된 차량 구동시 발생하는 차량 이음을 없애주는 효과가 있다.The present invention is to overcome the above-mentioned conventional problems, by forming a restraining means for restraining the lower part of the forging to be worked on the workbench of the high frequency heat treatment apparatus to prevent the lower part of the forging from the upper part during the high frequency heat treatment work to improve the quality of the forged product There is an effect of stabilizing and eliminating the play of the joint in the final assembly has the effect of eliminating the vehicle joints generated when driving the forged vehicle is mounted.
