Description
제1도는 본 고안 실시작동 예시도로서 지석반의 측면도.1 is a side view of the grindstone as an exemplary operation of the present invention.
제2도는 제1도의 중앙단면 확대도.2 is an enlarged cross-sectional view of the center of FIG.
본 고안은 회전 지석반의 개량에 관한 것이다. 종래의 회전지석반은 박팍형으로 구성된 절단용 회전지석판과 비교적 후판형으로 구성된 옵셋트용 회전 지석반으로 구분된다. 한편 가공물을 절단할 시는 절단용 회전지석반으로 하고, 또 가공물을 마삭할시는 옵셋트용 회전지석반으로 각각 구분하여 사용하는 것이 통에 이었다.The present invention relates to an improvement of a rotating grindstone. Conventional rotary grindstone is divided into a rotary grindstone for cutting consisting of a thin pack and a rotary grindstone for offset consisting of a relatively thick plate. On the other hand, when cutting a work piece, it was used as the cutting wheel for cutting, and when grinding a work piece, it used to divide it into the rotary wheel for offset.
여기서 종래의 절단용 회전지석반의 유효부 즉 절단용 회전지석반을 소정의 구동축에 취착시취서 사용할시는 절단작업량에대응해서 그의 회전 지석반은 점차 마모하게 되어 사용 불능하게 되는 것이므로, 실제지석반의 사용가능한 면적은 사용불능케 될시의 면적과 비해서 적으므로서 이와 같이 사용불능하여 폐기되는 손실량은 크다.Here, when the effective portion of the conventional cutting wheel for cutting, that is, the cutting wheel for cutting is used on a predetermined drive shaft, the rotating grinding wheel becomes gradually worn out and becomes unusable according to the amount of cutting work. Since the usable area is smaller than the area when it becomes unavailable, the amount of waste that is discarded due to such use is large.
따라서 지석반의 성형원재가 부족되는 현실에서 이와같은 소모율의 개선 타개가 필요하게 된다.Therefore, it is necessary to overcome the improvement of the consumption rate in the reality that the molding material of the grindstone plate is insufficient.
본 고안은 이같은 요구에 대한 해결을 목적으로 연구개발된 것으로 본 고안의 요지를 설명하면 먼저 옵셋트용 회전지석반의 주연부에, 지석반의 두께보다 얇은 절단용 지석부를 연장시켜서 단일체로 형성케한 회전 지석반을 개발케 한 것이다.The present invention has been researched and developed for the purpose of solving such a requirement. When explaining the gist of the present invention, the rotating grindstone formed by forming a unitary body by extending the cutting grindstone thinner than the thickness of the grindstone slab firstly. To develop a class.
따라서 이와 같은 회전 지석반의 외주연부는 절단용 지석반의 용도로 되고 그외의 부분은 옵셋트용 지석부로 구성케함으로서, 그 회전 지석반은 최초 절단용 지석반으로 사용한 후 즉, 외주부가 마모한 후의 나머지부분을 옵셋트용 연마지석반으로 계속 사용이 가능한 것이므로, 결과적으로 두가지 용도로 사용이 가능하여 사용상 편리하고 지석반의 성형원재의 절감을 기할수 있는 특징을 갖춘 것이다.Therefore, the outer periphery of the rotating grindstone is used for cutting grindstone and the other part is composed of offset grindstone, and the rotary grindstone is used as the first cutting grindstone, that is, after the outer periphery wears. Since the part can continue to be used as an offset abrasive grindstone, it can be used for two purposes as a result, and it is convenient to use and can save the molding material of the grindstone.
본 고안을 첨부도면에 따라 실시예와 같이 이를 상세히 설명하면 다음과 같다.Referring to the present invention in detail as in the embodiment according to the accompanying drawings as follows.
(1)은 본 실시예에서 설명하는 회절 지석반으로서 지석반(1)은 지립에 접착제(페놀수지)의 적당량과 착색제등을 혼연시킨 지석반 성형원료(2)와 보강재로서 그중간 층에는 그라스화이봐크로스(3)를 내장하여 성형케한 것이다.(1) is a diffraction grindstone described in the present embodiment, and the grindstone (1) is a grindstone shaped raw material (2) in which an appropriate amount of an adhesive (phenolic resin) and a colorant are mixed with abrasive grains and a reinforcing material in the middle layer thereof. It is made by forming a fiber cross (3).
이같이 성형된 회전지석반(1)은 도면에 명시된 바와 같이 회전식서의 반경(a)으로 하는 종래의 공지인 옵셋트형 회전 지석부(1')에다 지석부(1")를 구성케 한 것이다.The shaped grinding wheel 1 thus formed constitutes a grindstone 1 " in a conventionally known offset rotary grindstone 1 ' .
이 옵셋트용 회전 지석부(1')의 주연부에는 옵셋트용 회전지석부(1') 두께의 2분지의 1의 한도이고 그폭(b)은 절단용 지석부(1")와 동일체로서 구성되어 있다.The periphery of the rotary grindstone portion 1 'for offset is the limit of one half of the thickness of the rotary grindstone portion 1' for offset, and the width b is formed as the same as the cutting grindstone portion 1 ". It is.
도면중 미설명부호(4)는 회전축에 결부케 하는 구멍이다. 본 고안에서는 회전지석반(1)은 상술한 바와 같이 옵셋트 회전지석부(1')의 주연부를 박판형으로 하여 절단 목적으로 하는 절단 지석부(1")를 연장구성케 한 것이므로 실사용시는 회전지석반(1)로서 절단목적에 사용하는 것이고 그후에 다시 절단용 지석부(1")가 마손되었을 시 그 잔여부분(1')으로서 옵셋트용회전 지석반으로 사용을 함으로서 본 회전지석반(1)은 조금도 손실됨이 없이 계속하여 유효 적절하게 사용할 수 있는 것이다. 또한 본 지석반의 중심부는 두껍게 형성되어 있으므로 지석의 강도를 유지케 하여서 절단, 연마의 작업도중에 심축이나 지체에 대하여 의곡성을 없이할 수 있는 것이다.In the figure, reference numeral 4 denotes a hole that is connected to the rotating shaft. In the present invention, the rotary grindstone 1 is formed in the shape of the periphery of the offset rotary grindstone 1 'as described above to extend the cutting grindstone 1 " for cutting purposes. It is used for cutting purposes as a grindstone (1), and when the grinding grindstone (1 ") is crushed again, the remaining grindstone (1 ') is used as a rotary grindstone for offset as the remaining part (1'). ) Can be used effectively and continuously without any loss. In addition, since the center of the grindstone plate is formed thick, the strength of the grindstone can be maintained, so that it is possible to remove the curvature of the mandrel and the lag during cutting and polishing.
상술함과 같이 종래의 회전지석반을 어느 한도로 외형이 마모 되었을시는 이를 폐기하였고 다시 2차로 사용치 않으므로서 지석반의 소모와 이에 따르는 원재의 낭비가 있었다.As described above, when the appearance of the conventional rotary grinding wheel was worn to any limit, it was discarded and the second grinding wheel was not used again, resulting in the consumption of the grinding wheel and the waste of raw materials.
본 고안에 의한 절단용 회전 지석반을 중심부를 후형으로 하여서 중간부의 강도를 높이고 따라서 외주의 절단용 지석부(1")를 더욱 후형으로 할수 있으므로 피가공물을 절단할 시에 마찰 저항을 적게 하면서 예민한 절단 작용을 할수 있도록 하고 또한 마모되는 절미량이 적게되며, 따라서 가공작업을 효율화할 수 있는 것이다.The rotary grinding wheel for cutting according to the present invention can be made thicker at the center, thereby increasing the strength of the intermediate part, and thus the cutting grinding wheel part 1 "can be made thicker at the outer periphery, thereby reducing the frictional resistance when cutting the workpiece. The cutting action can be performed and the amount of cuts to be worn is reduced, thus making the machining work more efficient.
