본 발명은 SFL 절단면취장치에 관한 것으로서, 보다 상세하게는 안전벨트의 구속력을 일정 레벨로 유지시키는 부품인 SFL을 절단 및 면취하기 위한 장치이다.FIELD OF THE INVENTION The present invention relates to an apparatus for cutting and chamfering an SFL, which is a component for maintaining a restraining force of a seat belt at a constant level.

SFL이란 Stopper Force Limiter의 줄임말로서, 그 형태는 도 1 및 도 1a에 도시되어 있으며, 체중, 체형감지 안전벨트에 들어가는 제품이다. 이런 SFL의 특성상 높은 경도가 요구되어 열처리를 통하여 경도를 증가시켜 사용하고 있으며, 보통 800~900℃의 가열후 일정시간(약 50분) 유지하고 이후 오일에서 소입(quenching)처 리를 하고 응력을 없애기 위한 템퍼링처리를 한다.SFL is abbreviation of Stopper Force Limiter, which is shown in FIG. 1 and FIG. 1A, and is a product that enters the weight and body type sensing seat belt. Due to the nature of such SFL, it is required to have high hardness and it is used by increasing the hardness through heat treatment. It is usually maintained at a temperature of 800 ~ 900 ℃ for a certain period of time (about 50 minutes) and then subjected to quenching treatment in oil, Perform a tempering process to remove.

하지만, 일반적인 소재의 경우 이러한 열처리 공정을 거치게되는 동안 급냉시 체적 변화에 따른 내부 응력이나 열에 의한 열응력 등이 잔류하게 되고 그 응력으로 인해 변형을 일으키게 되어 부품의 정밀도를 떨어뜨리게 된다.However, in the case of general materials, the internal stress or thermal stress due to the volume change at the time of quenching remains while being subjected to the heat treatment process, and the stress is caused by the stress, and the precision of the part is lowered.

이러한 응력에 의한 변형은 소재의 형상에도 영향을 주며 SFL의 경우 절단전 부품은 파이프 형태에 안쪽에 나사가 나있는 너트의 형상과 유사하다. 이와 같은 파이프 형태이므로 잔류응력에 의한 변형이 중심으로 부터 전방향 균일하게 동시적으로 발생하게 되어 열처리에 의한 형상정밀도의 저하가 감소하게 된다.Such stress-induced deformation affects the shape of the workpiece, and in the case of SFL, the part before cutting is similar to the shape of a nut that is threaded on the inside of the pipe. Because of such a pipe shape, deformation due to residual stress occurs uniformly in all directions from the center simultaneously, and the reduction in shape accuracy due to heat treatment is reduced.

하지만, 절단공정을 용이하게 하기위해서 소재를 먼저 절단하고 이후에 열처리를 할 경우에는 소재의 형상이 완전한 원형이 아니므로, 결국 잔류응력에 의한 변형이 위치에 따라 다르게 발생하게 되어 형상정밀도가 현저하게 감소하게 된다.However, in order to facilitate the cutting process, when the material is cut first and then heat treatment is performed, the shape of the material is not completely circular, so that deformation due to the residual stress occurs differently depending on the position, .

더욱이 SFL 부품의 경우에는 도 2에 도시된 바와같이, 나사형태로 체결되며 조정거리 내에서 원활하게 움직여야 한다. 그러나 상술한 바와 같이 절단후에 열처리를 할 경우 절단면의 나사부분에서 형상정밀도가 현저하게 감소하여 체결자체가 불가능하거나 체결하여도 움직임이 원활하지 않게되어 SFL 부품으로서의 기능을 발휘하지 못하게 된다.Furthermore, in the case of the SFL component, as shown in Fig. 2, it is fastened in the form of a screw and must move smoothly within the adjustment distance. However, as described above, when the heat treatment is performed after cutting, the shape accuracy is significantly reduced at the thread portion of the cut surface, so that the fastening itself can not be performed or the movement is not smooth even when fastened.

또한, 수공작업을 할 경우 연마석의 소모량이 많아 생산비용이 상승하며, 연마석 교환시간 등으로 인해 생산성이 저하되며, 연마석의 절단시 나사부의 눈막힘으로 제품의 품질이 저하되며, 절단시에 발생하는 분진으로 대기환경을 오염시키게 된다.In addition, when handwork is performed, the cost of production of the abrasive is increased due to high consumption of the abrasive stone, the productivity is decreased due to the replacement time of the abrasive stone, and the quality of the product is decreased due to the clogging of the abrasive during cutting. The dust pollutes the atmospheric environment.

따라서, 본 발명은 SFL 부품 제조를 위해서는 열처리후의 높은 경도를 가진 제품을 자동으로 절단할 수 있는 절단장치를 제공하는데 그 목적이 있다. Accordingly, it is an object of the present invention to provide a cutting apparatus capable of automatically cutting a product having a high hardness after heat treatment for manufacturing SFL parts.

또한, 연마석 대신 후술할 CBN 커팅휠, CBN 휠을 사용하여 공구의 수명을 늘여서 제품의 생산성을 높이고 생산비용은 낮추는 데 또 다른 목적이 있으며, 수작업이 아닌 기계가공을 함으로서 제품의 품질을 향상시키는 데 또 다른 목적이 있다.In addition, CBN cutting wheel and CBN wheel, which will be described below, are used instead of the grinding stone to increase the tool life, thereby improving the productivity of the product and lowering the production cost. Another object is to improve the quality of the product by machining There is another purpose.

본 발명은 SFL 절단장치에 관한 것으로서, 보다 상세하게는 체중, 체형감지 안전벨트의 핵심부품인 SFL의 자동 절단면취장치이다. 상술한 바와 같이, SFL은 그 형상의 변화를 적게하기 위해 열처리를 한 후 절단을 하므로, 비교적 높은 경도의 재료를 절단할 수 있는 장치가 필요하다.FIELD OF THE INVENTION The present invention relates to an SFL cutting apparatus, and more particularly, to an automatic cut surface removing apparatus of SFL which is a core component of a weight and body type detecting seat belt. As described above, the SFL is cut after the heat treatment to reduce the change in the shape thereof, and therefore, a device capable of cutting a material having a relatively high hardness is required.

상기 컷팅휠(11) 및 면취휠(31,41)은 보통 HRC 50 이상이 되는 공구강 등의 스틸재에 주로 사용하는 CBN컷팅휠 및 CBN휠을 사용하는 것이 바람직하며, 상기 CBN컷팅휠 및 CBN휠의 특성상 기계의 진동을 적게하는 것이 요구된다.The cutting wheel 11 and the chamfered wheels 31 and 41 preferably use a CBN cutting wheel and a CBN wheel which are mainly used for a steel material such as a tool steel having an HRC of 50 or more. The CBN cutting wheel and the CBN wheel It is required to reduce the vibration of the machine.

먼저, 열처리된 파이프형의 소재가 소재공급관(70)을 따라 투입되면 상기 소재는 마운트플레이트(29)에 안착된다. 이후 에어실린더1(12)의 작동에 의해 푸쉬로드(13)가 전진하게 되는데, 이 때는 소재를 컷팅휠(11) 앞까지는 고속 이동하며, 상기 컷팅휠(11)에 도달하기 약 5~10mm 전에 쇼크업쇼바(17)에 의하여 이송속도를 감쇄시켜 절단속도를 조절하게 된다.First, when the heat-treated pipe-like material is inserted along the material supply pipe 70, the material is seated on the mount plate 29. The push rod 13 is moved forward by the operation of the air cylinder 1 12 and at this time the material is moved to the front of the cutting wheel 11 at a high speed and is moved about 5 to 10 mm before reaching the cutting wheel 11 And the cutting speed is adjusted by attenuating the feed speed by the shock-up bar 17.

상기 푸쉬로드(13)는 도 4와 도 4a 및 도 4b에 도시된 바와 같이 내부에 컷팅홈(21)이 축방향으로 길게 형성되어져 있어 소재의 컷팅이 끝날 때까지 컷팅휠(11)에 대한 간섭을 받지 않는다.
즉, 푸쉬로드(13)의 움직임에 대해 컷팅휠(11)은 간섭을 받지 않는다.As shown in FIGS. 4 and 4A and 4B, the push rod 13 has a cut groove 21 formed therein to be long in the axial direction, so that interference with the cutting wheel 11 .
That is, the cutting wheel 11 is not subject to interference with the movement of the push rod 13.

또한, 상기 컷팅휠(11)은 SFL 제품의 특성상 양쪽 컷팅휠의 높이는 다르게 구성되어 있다.In addition, the cutting wheel 11 has different heights of both cutting wheels due to the nature of the SFL product.

또한, 사용자의 필요에 따라 푸쉬로드(13)의 감속을 단계별로 할 수 있는데, 경도가 비교적 높은 제품은 쇼크업쇼바(17)에 의한 푸쉬로드(13)의 감속을 크게하 여 천천히 컷팅되도록 하며, 이와는 반대로 경도가 비교적 낮은 제품은 쇼크업쇼바(17)에 의한 푸쉬로드(13)의 감속을 적게하여 비교적 빠르게 컷팅되도록 한다.In addition, the deceleration of the push rod 13 can be made step by step according to the user's needs. In the case of a product having a relatively high hardness, the deceleration of the push rod 13 by the shock up bar 17 is increased to be slowly cut And on the contrary, a product having a relatively low hardness reduces the deceleration of the push rod 13 by the shock absorber 17, so that it is cut relatively quickly.

이후, 컷팅후의 제품은 컷팅제품적재부(60)에 적재되게 하고, 컷팅후의 스크랩은 스크랩박스(90)로 배출된다. 상기 컷팅제품적재부(60)는 에어실린더2(24)의 동작과 제어부(도시하지 않음)의 제어로서 최소 1개에서 최대 10개까지 선택하여 적재될 수 있다. Thereafter, the product after the cutting is allowed to be stacked on the cut product mounting portion 60, and the scrap after cutting is discharged to the scrap box 90. [ The cutting product loading section 60 can be loaded with a minimum of one to a maximum of ten as the operation of the air cylinder 2 (24) and the control of a control section (not shown).

The outer diameter face fitting portion 30 includes a spindle 20 rotated by a motor 18, an outer diameter chamfered wheel 31 rotated by the spindle 20, A wheel fixing bolt 27 for fixing the outer diameter chamfering wheel 31, and a V block 23 on which a workpiece is seated.

상기 컷팅제품적재부(60)에 셋팅된 수만큼 제품이 적재되면 에어실린더2(24)가 V블록(23)을 따라 제품을 밀어주며, 외경면취휠(31)에 의해 제품이 외경면취가 된다.When the number of products set in the cut product loading unit 60 is set, the air cylinder 2 (24) pushes the product along the V block 23, and the outer diameter chamfer wheel 31 causes the product to be chamfered .

도 7은 본 발명에 의한 내경면취부(40)의 구성도로서, 상기한 외경면취부(30)의 구성과 유사하게, 모터(18)에 의해 회전되는 스핀들(20)과, 상기 스핀들(20)에 의해 회전되는 내경면취휠(41)과, 상기 내경면취휠(41)을 고정하는 휠고정볼트(27)와, 소재가 안착되는 V블록(23)으로 구성되어 있다. 7 is a configuration diagram of the inner diameter face attaching portion 40 according to the present invention.

에어실린더2(24)가 V블록(23)을 따라 제품을 밀어주며, 상기 외경면취부(30)에 의해 외경면취된 제품이 내경면취휠(41)에 의해 내경 면취가 된다.The air cylinder 2 24 pushes the product along the V block 23 and the inner diameter chamfered wheel 41 makes the inner diameter chamfered product by the outer diameter chamfered portion 30.

이후, 외경, 내경 면취가 끝난 제품은 제품박스(80)에 적재되게 된다.Thereafter, the product having the outer diameter and the inner diameter chamfered is loaded on the product box 80.
