본 고안은 위치결정용 돌기를 가진 금속판재의 엠보싱(Embossing)장치에 관한 것으로, 특히 돌기 부분의 강도가 우수하면서도 돌기부분의 높이를 정밀하게 조정할 수 있도록 한 것이다.The present invention relates to an embossing device of a metal plate having a positioning projection, and particularly to the strength of the projection part and to precisely adjust the height of the projection part.

금속판재에 위치결정용 돌기를 형성하기 위한 종래의 엠보싱장치, 예를들어 제3도에 도시한 바와 같은 장치는 다이(1)에 돌기와 같은 크기의 구멍(10)을 뚫고 프레스램이 하강하면 스트리퍼(4)가 금속판재(7)에 접속됨과 동시에 펀치(6)가 하강하여 돌기부가 형성되도록 되어 있으나 이러한 종래이 장치로는 금속판재의 특성상 돌기부를 소재 두께의 절반 이상의 높이(h)로 형성할 수 없는 결점이 있고 또 돌기부에 외력이 가해지는 경우 제4도와 같이 크랙(11)이 발생하여 그 부품전체가 손상되는 결점이 있었다.A conventional embossing device for forming positioning projections in a metal plate, for example, a device as shown in FIG. 3, drills a hole 10 of the same size as the projection in the die 1 and strippers when the pressram descends. (4) is connected to the metal plate (7) and at the same time the punch (6) is lowered to form a projection, but this conventional device can form the projection to a height (h) of more than half the thickness of the material due to the characteristics of the metal plate material If there is a flaw that is not present and an external force is applied to the protrusion, crack 11 occurs as shown in FIG.

본 고안은 종래의 이와 같은 결점을 해결하기 위한 것으로 이를 첨부된 도면에 의해 더욱 상세히 설명하면 다음과 같다.The present invention is to solve such a deficiency of the prior art described in more detail by the accompanying drawings as follows.

다이(1)에 돌출턱(2a)을 가진 받침판(2)과 한쌍의 다이버튼(3)를 고정하여 다이버튼(3)이 다이(1)의 표면으로 부터 약간 돌출되도록 하고 스트리퍼(4)에는 스트리퍼(4)의 표면보다 약간 돌출된 다이버튼(5)를 고정함과 함께 그 중심부에 펀치(6)를 설치하여서 된 것으로, 도면중 미설명 부호 7은 금속판재, 8은 금속판재의 상방요입부, 9는 하방요입부이다.The base plate 2 having the protruding jaw 2a and the pair of die buttons 3 are fixed to the die 1 so that the die buttons 3 slightly protrude from the surface of the die 1 and the stripper 4 The die button 5 which protrudes slightly from the surface of the stripper 4 is fixed, and the punch 6 is installed in the center thereof. In the drawing, reference numeral 7 denotes a metal plate, and 8 denotes an upward direction of the metal plate. 9 is a downward recess.

이와 같이 구성된 본 고안은 첨부 도면 제1도와 같이 다이(1)위에 금속판재(6)를 올려놓고 프레스램(도시는 생략함)을 하강시키면 먼저 스트리퍼(4)에 고정된 다이버튼(5)과 다이(1)에 고정된 다이버튼(3)에 의해 금속판재(7)의 상방과 하방에 각각 요입부(8) (9)가 형성되고, 이러한 상태에서 펀치(6)를 하강시키면 체적 일정조건과 압출의 원리가 적용되어 상, 하 요입부(8) (9) 체적만큼의 재료가 받침판(2)에 형성된 돌출턱(2a)의 외측으로 밀려나가면서 돌기부가 형성되는 것이다.The present invention configured as described above has the die button 5 fixed to the stripper 4 when the metal plate 6 is placed on the die 1 and the pressram (not shown) is lowered as shown in FIG. The recesses 8 and 9 are formed above and below the metal plate 7, respectively, by the die button 3 fixed to the die 1, and the punch 6 is lowered in this state to make the volume constant. By applying the principle of over-extrusion, the protrusions are formed while the material corresponding to the volume of the upper and lower recesses 8 and 9 is pushed out of the protruding jaw 2a formed on the support plate 2.

이때 돌기부의 높이(H)는 펀치(6)의 하강 압력을 조정하는 수단에 의해 제한된 범위내에서 임의의 높이로 형성할 수 있게 되며 돌기부가 압출의 원리에 의해 형성된 것이기 때문에 단순 펀칭에 의해 형성된 종래의 것에 비해 월등높은 강도를 가지게 되고 따라서 반복 사용시에도 돌기부에 크랙이 발생하지 않게 되는 효과가 있다.At this time, the height (H) of the projections can be formed at any height within a limited range by means of adjusting the lowering pressure of the punch (6) and the conventional projection formed by simple punching because the projections are formed by the principle of extrusion. Compared to that of having a much higher strength, and therefore, there is an effect that the crack does not occur in the projections even when repeated use.
