3 : 연마사 a : 연마구3: grinding yarn a: grinding wheel

본 고안은 주로 경연삭에 이용 될 수 있는 탄성 연마구에 관한 것으로, 육면체의 스폰지블럭 표면에 접착제를 이용하여 연마사를 균일하게 도포 접착 시킴으로써 굴신력과 복원력이 우수하여 연마면을 균일하게 연마시킬 수가 있으며, 돌출 또는 요입 상태의 굴곡진 연마면을 효과적으로 연마 할 수 있어서, 작업능률 향상은 물론 연마면을 고루 연마 시킬 수 있도록 하는데 그 목적이 있는 것이다.The present invention mainly relates to an elastic polishing tool that can be used for light grinding, by uniformly applying and bonding the abrasive yarn to the surface of the sponge block of the cube by using an adhesive to excellent polishing and restoring power to uniformly polish the polishing surface It is possible to effectively grind the curved polishing surface of the protruding or concave state, and the purpose is to improve the work efficiency as well as to polish the polishing surface evenly.

종래에는 통상 샌드페이퍼라하여 직포나 종이 표면에 연마사가 부착된 것을 사용하여 왔던 바, 이들은 연마포 또는 연마페이퍼 자체가 얇은 직포나 종이여서 사용중에 쉽게 절곡 또는 절단되는 폐단이 있게 되고 연마시에 접착면에 미치는 압력의 분배가 균일하지 못하여 연마면이 블규칙한 결점이 있게 되며, 특히 가구 등의 목재를 연마 할 때는 이러한 현상이 더욱 심하게 되고 조각된 연마면이나 굴곡 요철을 가진 연마면일때는 고루 연마되지 않는 문제점이 있게 되는 것이다.Conventionally, sand paper has been used as the abrasive is attached to the surface of the woven fabric or paper, these are a thin cloth or paper of the polishing cloth or paper itself has a closed end that is easily bent or cut during use, and the adhesive surface during polishing The pressure distribution is not uniform, so that the polished surface has irregular defects, especially when grinding wood such as furniture, this phenomenon becomes more severe, even when the polished surface with carved or curved irregularities There will not be a problem.

또한 직포나 페이펴로된 연마지는 연마시에 생기는 분전이 연마사사이에 끼여 있게 되면, 이를 제거하기가 곤란하여 연마 효율이 떨어지게 되고, 얼마 사용하지 못하고 버려야 하는 폐단이 있게 되는 것이다.In addition, when the abrasive produced during polishing is sandwiched between abrasive yarns, it is difficult to remove the abrasive, resulting in poor polishing efficiency, and there is a waste that must be thrown away.

그리고 스폰지블럭의 일면에 연마면이 형성된 연마구가 일본 실용신안 공보 소35-2586호로 알려지고 있으나, 이는 단순히 손으로 잡기가 편리한 육면체의 연마구를 얻기 위한 목적으로 통상적인 직포로된 연마지를 스폰지블럭 표면에 부착한 정도에 불과한 것이여서 이는 스폰지블럭으로 인해 손으로 잡고 작업하기가 편리한 효과는 얻을 수 있으나, 본 고안과 같이 연마면과 접촉시에 요구되는 우수한 탄력과 굴신력 및 복원력을 기대 할 수가 없으며, 특히 직포에 부착된 연마사는 스폰지블럭의 굴신력이나 복원력을 그대로 전달받지 못하게 됨으로, 통상적인 연마포와 같아서 요철부를 고루 연마시킬 수가 없고 연마면이 딱딱하여 피삭물의 스크랩이 부착 시킴으로서 연마사 자체가 스폰지블럭의 표면에선 일체화되어 피복층을 이루게 됨으로 스폰지블럭의 탄성을 그대로 유지할 수가 있어서, 굴신력과 탄력 및 복원력이 유지되고 하중분배가 균일하며, 물세척 등의 방법 으로 스크랩을 제거 할 수 있게 한 것으로, 이하 첨부 도면에 의거 설명하면 다음과 같다.Although a polishing tool having a polishing surface formed on one surface of the sponge block is known as Japanese Utility Model Publication No. 35-2586, this is simply a polishing cloth made of a conventional woven cloth for the purpose of obtaining a polishing tool of a hexahedron which is easy to hold by hand. Since it is only attached to the surface of the block, it can be obtained by the sponge block, which is convenient to hold and work with. However, as in the present invention, it can be expected to have excellent elasticity, flexibility, and resilience required in contact with the abrasive surface. In particular, since the abrasive yarn attached to the woven fabric does not receive the stretching force or the restoring force of the sponge block as it is, it is the same as a conventional abrasive cloth and cannot polish the uneven parts evenly. The sponge itself is integrated on the surface of the sponge block to form a coating layer. In not maintain the elasticity of Luck as it is, the gulsin strength and elasticity and restoring force maintained, and the load distribution is uniform, that enables to remove the scrap, for example by washing with water, it will be described based on the accompanying drawings as follows.

육면체의 스폰지블럭(1)의 표면에 접착제를 도포하여 접착층(2)를 형성시키고 접착층(2)에는 연마사(3)을 접착시켜 연마구(a)를 구성한다.An adhesive is applied to the surface of the sponge block 1 of the hexahedron to form the adhesive layer 2, and the abrasive yarn 3 is adhered to the adhesive layer 2 to constitute the polishing tool a.

이와같이된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention as described above is as follows.

스폰지블럭(1)의 표면에는 기포에 의해 크고 작은 굴곡이 무수히 형성되 있으므로, 굴곡이 형성된 표면에 접착층(2)의 형성되있고 표면 굴곡부로 침투된 접착층(2)위에 연마사가 접착되 있어서, 사용중에 심한 마찰이나 충격 또는 굴신작용이 반복 되더라도 연마사(3)이 이탈되는 폐단이 없으며, 스폰지블럭(1)면에 직접연마사(2)가 부착된 상태여서 피삭물을 가공할 때 연마사 자체가 스폰지의 소프트한 소재 특징에 의해 가공방향에 따라 자유롭게 유동되면서 연마하기 때문에 연마사(3)의 입도는 일정하더라도 피삭물이 깍기는 홈은 누르는 압력의 차이에 따라 깊이에 차이가 나므로 동일한 입도에서도 스폰지의 굴신도와 압입력에 따라 피삭물의 표면 조도가 달라 질 수 있어 피삭물의 조건에 적절히 대응할 수 있는 것이며, 연마제의 유동에 의해 스크랩이 연마제 사이에 꽉 끼이지 않게 용이하게 털어낼 수 있는 효과가 있는 것이다.On the surface of the sponge block 1, numerous large and small bends are formed by bubbles, and thus, an abrasive layer is formed on the surface where the bend is formed and an abrasive layer is adhered to the adhesive layer 2 that has penetrated into the surface bent portion. Even if the friction, impact, or stretching action is repeated, there is no closed end from which the abrasive yarn 3 is detached, and the abrasive yarn itself is sponge when the workpiece is processed because the abrasive yarn 2 is attached to the sponge block 1 surface. Due to the soft material characteristics of the abrasive, it is free to flow along the direction of processing, so even though the grain size of the abrasive yarns 3 is constant, the grooves for cutting the workpieces differ in depth depending on the pressure of pressing the workpiece. The surface roughness of the workpiece may vary depending on the elongation and pressure input, so that it can respond appropriately to the conditions of the workpiece. There is an effect that can be easily shaken off without being pinched between the abrasives.

또한, 스폰지블럭(1)의 탄력성 때문에 하중분배가 균일하여 연마면이 고르게 연마되며 연마시에 생기는 분진은 스폰지블럭(1)의 탄력성 때문에 연마사(3)사이에 흡착되는 것을 막을 수 있으며, 분진이 연마사(3)사이에 끼어 있더라도 가볍게 털면 분진이 쉽게 제거되며, 털어서 제거되지 않는 분진은 스폰지(1)에 물을 적셔서 빨아주면 깨끗하게 제거됨으로 오랫동안 사용할 수가 있는 것이다.In addition, due to the elasticity of the sponge block 1, the load distribution is uniform, so that the polishing surface is evenly polished, and dust generated during polishing can be prevented from being adsorbed between the abrasive yarns 3 due to the elasticity of the sponge block 1, Even if it is sandwiched between the abrasive yarns (3), dust is easily removed by dusting, and dust that can not be removed by wiping it with a sponge (1) soaked with water to be removed is clean and can be used for a long time.

특히 본 고안은 스폰지블럭(1)의 탄력과 굴신력에 의하여 연마면이 굴곡이 지거나 곡면상태 이더라도 접촉면이 균일하여 고루 연마시킬 수가 있고 스폰지블럭(1)은 손으로 잡고 작업하기가 편리한 잇점을 얻게 되는 것이다.In particular, the present invention, even if the polishing surface is curved or curved due to the elasticity and flexural force of the sponge block (1) can be uniformly polished evenly contact surface and the sponge block (1) has the advantage that it is convenient to hold and work by hand Will be.
