이하 본 발명의 체적 변동이 가능한 체결부재에 대한 각 구성요소를 첨부한 도면을 참조하여 하나씩 살펴보면 다음과 같다.Hereinafter, the components of the fastening member capable of changing the volume of the present invention will be described with reference to the accompanying drawings, one by one.

우선 본 발명인 체적 변동이 가능한 체결부재는 금형부재(100)를 통해 체결부재(200)가 주물(鑄物, casting)되는 것을 기본으로 한다.First, the fastening member capable of changing the volume of the present invention is based on the casting member 200 being cast through the mold member 100.

도 2 및 도 3에 도시된 바와 같이 금형부재(100)는 성형홈(110)이 형성되어 이하 기술하게 될 체결부재(200)의 외형을 형성할 수 있게 한다.As shown in FIGS. 2 and 3, the mold member 100 may form a molding groove 110 to form an outer shape of the fastening member 200 to be described below.

한편, 체결부재(200)는 금형부재(100)의 성형홈(110)에 용해된 스틸을 충진시켜 너트 형상의 체결부재(200)가 성형되도록 한다.On the other hand, the fastening member 200 is filled with the molten steel in the molding groove 110 of the mold member 100 so that the nut-shaped fastening member 200 is molded.

이때, 금형부재(100)의 성형홈(110) 내주면 상단에는 오목부(111)가 형성되도록 하여 체결부재(200) 성형 시 상기 체결부재(200) 외주면 상단에 돌출부(221)가 형성되도록 한다.At this time, the recess 111 is formed at the upper end of the molding groove 110 of the mold member 100 so that the protrusion 221 is formed at the upper end of the outer peripheral surface of the fastening member 200 when the fastening member 200 is formed.

또한, 금형부재(100)의 성형홈(110) 중앙에는 외주면에 나사산이 형성된 돌출바(112)가 상방으로 구비되어 체결부재(200) 성형 시 상기 체결부재(200) 중앙에 체결홀(201)이 형성되며 상기 체결홀(201) 내주면에는 나사산이 성형되게 하여 체결부품과의 결합 작업이 이루어질 수 있게 하는 것이 바람직하다.In addition, the center of the molding groove 110 of the mold member 100 is provided with a protrusion bar 112 formed with a screw thread on the outer peripheral surface upwards when forming the fastening member 200, the fastening hole 201 in the center of the fastening member 200. It is preferable to form a screw thread on the inner circumferential surface of the fastening hole 201 to allow a coupling operation with the fastening component.

한편, 금형부재(100)의 성형홈(110) 상단 내경이 중단 내경 보다 넓게 형성되어 체결부재(200) 성형 시 상기 체결부재(200)의 상단이 플랜지 형상으로 성형되도록 하는 것이 바람직하다.On the other hand, it is preferable that the inner diameter of the upper end of the molding groove 110 of the mold member 100 is wider than the stop inner diameter so that the upper end of the fastening member 200 is shaped into a flange when the fastening member 200 is formed.

이때, 체결부재(200)는 내주면에 나사산이 형성된 몸체부(210)와, 상기 몸체부(210) 상단에 형성되는 플랜지부(220)로 이루어지되, 상기 몸체부(210)의 내주면에는 체결홀(201)이 형성되며, 상기 플랜지부(220)의 내주면에도 상기 몸체부(210)의 체결홀(201)이 연장 형성되도록 하여 체결 작업 시 상기 체결부재(200) 끝까지 체결이 이루어질 수 있게 한다.At this time, the fastening member 200 is composed of a body portion 210 formed with a screw thread on the inner circumferential surface, and a flange portion 220 formed on the top of the body portion 210, the fastening hole on the inner circumferential surface of the body portion 210 A 201 is formed, and the fastening hole 201 of the body portion 210 is extended to the inner circumferential surface of the flange portion 220 so that the fastening can be performed to the end of the fastening member 200 during the fastening operation.

여기서, 체결부재(200)의 플랜지부(220) 상면에는 삽입홈(222)을 형성시키고 상기 삽입홈(222)에는 자성체(223)를 삽입시킨다. Here, the insertion groove 222 is formed in the upper surface of the flange portion 220 of the fastening member 200 and the magnetic body 223 is inserted into the insertion groove 222.

이때, 체결부재(200)의 삽입홈(222)에 자성체(223)를 삽입시키는 것은 상기 체결부재(200)를 통한 체결 작업 시 상기 체결부재(200)가 체결시키고자 하는 결합부품에 일시적으로 접착시킬 수 있게 하여 체결 작업을 용이하게 진행할 수 있게 하기 위한 것이다.At this time, inserting the magnetic material 223 into the insertion groove 222 of the fastening member 200 temporarily adhering to the coupling part to be fastened by the fastening member 200 during the fastening operation through the fastening member 200. It is intended to facilitate the fastening operation by making it possible.

또한, 체결부재(200)의 돌출부(221)는 플랜지부(220)의 외주면에 형성되어 상기 플랜지부(220)에 삽입홈(222) 성형 시 체적 변동이 가능하게 함으로써, 프레스 작업으로 상기 삽입홈(222)이 형성됨으로 인해 상기 플랜지부(220)의 형상이 변형되는 것을 방지하게 된다.In addition, the protrusion 221 of the fastening member 200 is formed on the outer circumferential surface of the flange portion 220 to enable a volume change when forming the insertion groove 222 in the flange portion 220, the insertion groove by the press operation The formation of the 222 prevents the shape of the flange portion 220 from being deformed.

이처럼, 본 발명은 체결부재(200)의 체적 변동이 가능하게 하여 삽입홈(222) 성형 시 플랜지부(220)의 형상 변형을 방지하는 동시에 상기 삽입홈(222)과 체결부재(200)의 외경 사이의 간격을 연장시킴으로 인해 강성을 강화시킬 수 있게 한다.As such, the present invention enables the volume change of the fastening member 200 to prevent the deformation of the flange portion 220 when the insertion groove 222 is formed, and at the same time the outer diameter of the insertion groove 222 and the fastening member 200. By extending the interval between them it is possible to enhance the rigidity.

또한, 삽입홈(222)과 돌출부(221)는 체결부재(200)의 중심으로부터 일직선상에 성형되며, 상기 삽입홈(222)과 돌출부(221)는 2개 이상 일정한 간격을 가지고 성형되도록 하여 강성을 향상시킬 수 있게 하는 것이 바람직하다.In addition, the insertion groove 222 and the protrusion 221 is formed in a straight line from the center of the fastening member 200, the insertion groove 222 and the protrusion 221 is formed to be formed at a predetermined interval of two or more rigidity. It is desirable to be able to improve the
