금형형상면 수정을 위한 프레스 성형장치의 하부금형 고정구조{Lower mold fixing structure of press forming device for modifying mold shape surface}Lower mold fixing structure of press forming device for modifying mold shape surface}

본 발명은 상부금형과 하부금형을 이용하여 금속판재를 절단 및 절곡하여 원하는 형태로 가공하는 프레스 성형장치에 관한 것이며, 좀 더 구체적으로는 하부 금형을 베이스에 고정시킬 때 정확한 위치에 고정되게 하면서 성형작업시 측방향으로 가해지는 압력을 효과적으로 견딜 수 있도록 하부금형을 고정하는 구조에 관한 것이다.The present invention relates to a press molding apparatus for cutting and bending a metal sheet using an upper mold and a lower mold to process a desired shape, and more specifically, forming while fixing the lower mold to the base to be fixed at the correct position. It relates to a structure for fixing the lower mold so as to effectively withstand the pressure applied in the lateral direction during work.

주지된 바와 같이 프레스 성형장치는 주로 금속판에 압축력을 가하여 소성 변형시켜 여러 모양을 만들어내는 것으로, 시계·카메라의 정밀부품에서부터 자동차의 차체에 이르기까지 광범하게 이용되며, 특별히 가열하지 않고 가공할 수 있고, 짧은 시간에 정확한 치수·모양으로 가공할 수 있으며, 교환성이 있고 대량생산에 적합한 장치이다.As is well known, press forming equipment is mainly used to apply plastic force to a metal plate to form plastic deformations, and is widely used from precision parts of watches and cameras to automobile bodies, and can be processed without special heating. , It can be processed in a precise dimension and shape in a short time, and is a device that is interchangeable and suitable for mass production.

프레스 가공의 종류에는 커터(cutter)로 소정의 모양으로 절단하는 절단가공, 다이(die)와 펀치(punch)로 필요한 모양을 따내는 따내기가공, 재료를 필요한 모양으로 구부리는 굽힘가공, 원통·각통 등과 같은 바닥이 있고 이음매가 없는 용기를 만드는 드로잉 가공 등이 있다.Types of press processing include cutting processing to cut into a predetermined shape with a cutter, picking processing to obtain the required shape by die and punch, bending processing to bend the material into the required shape, cylinder· There is a drawing process to make a container with a bottom and a seamless container such as a square tube.

이러한 통상의 프레스 성형장치는 베이스 위의 하부다이에 하부금형을 설치하고 그 상부 이격된 위치에 설치되는 상부다이 저면에 상부금형을 설치한 다음, 하부다이 위에 소재를 얹고 상부다이를 하강시켜 상부금형과 하부금형이 맏물리면서 소재를 성형하거나 절단하는 것이다.In such a conventional press forming apparatus, a lower mold is installed on a lower die on a base, an upper mold is installed on a bottom surface of an upper die installed at a position spaced apart from the upper die, and then a material is placed on the lower die and the upper die is lowered. It is to mold or cut the material while the lower mold is mating.

이러한 구성에서 하부다이에 하부금형을 설치하는 구조는 작업시의 정밀성은 물론, 성형작업시 수직방향의 하중과 측방향으로 밀리는 하중이 하부금형에 그대로 전달되므로 하부금형을 고정시키는 것은 매우 중요한 구성임과 동시에 중요한 작업공정인데, 종래 하부다이에 하부금형이 설치되는 구성을 도 5a 및 도 5b를 통하여 살펴보면, 하부다이(1)의 상면과 하부금형(2)의 저면 일치하는 위치에 각각 키홈(3)(3')을 형성한 다음, 하부다이(1)의 키홈(3)에 별로도 준비된 키이(4)를 삽입하고 그 위에 하부금형(2)을 안착시키면서 키이(4)가 하부금형(2) 저면의 키홈(3')에 일치도록 안착시키는 것이다.In this configuration, the structure in which the lower mold is installed on the lower die is a very important component to fix the lower mold since the vertical load and the load pushed in the lateral direction are transmitted to the lower mold as well as the precision during work. At the same time, it is an important work process. Looking at the configuration in which the lower mold is installed on the conventional lower die through FIGS. 5A and 5B, the key grooves 3 are located at positions coinciding with the upper surface of the lower die 1 and the lower surface of the lower mold 2, respectively. )(3') is formed, the key 4 is inserted into the key groove 3 of the lower die 1, and the key 4 is mounted on the lower mold 2 while the lower mold 2 is seated thereon. ) It is to be seated so as to coincide with the key groove 3'of the bottom surface.

이러한 종래 고정구조에 의하면 하부다이(1)와 하부금형(2)에 각각 키홈(3)(3')을 가공하여야 함에 따른 가공의 어려움과 시간의 소요 및 번거로움이 있고, 별도의 부품인 하부다이(1)와 하부금형(2)에 각각 키홈(3)(3')을 정확한 위치에 만드는 것이 쉽지 않으며, 하부금형(2)을 하부다이(1)에 안착시키는 과정에서도 정확하게 키이(4)와 키홈(3)(3')을 안착시켜야 하기 위해 조심이 필요한 등 가공과 조립이 매우 번거로운 문제가 있었던 것이다.According to such a conventional fixing structure, there is difficulty in processing, time and trouble, and a hassle due to the need to process the key grooves 3 and 3'in the lower die 1 and the lower mold 2, respectively. It is not easy to make the key grooves 3 and 3'in the correct positions on the die 1 and the lower mold 2, respectively, and the key 4 is accurately adjusted even in the process of seating the lower mold 2 on the lower die 1. There was a very troublesome problem in processing and assembly, such as needing care in order to set the keyway 3 and 3'.

특허공개공보 10-2012-0017141(2012년02월28일)Patent Publication No. 10-2012-0017141 (February 28, 2012)

상기 문제점을 감안하여 안출된 본 발명은 하부금형을 하부다이에 고정하는 구성에 있어서, 가공과 조립이 매우 간단하고 편리한 고정구조를 제공하고, 가공과 조립에 따르는 시간과 비용을 절약하면서 안정적인 작업이 가능하도록 함을 목적으로 하는 것이다.The present invention devised in view of the above problems provides a very simple and convenient fixing structure in processing and assembly in a configuration for fixing the lower mold to the lower die, and provides stable operation while saving time and money associated with processing and assembly. The goal is to make it possible.

상기 목적을 달성하기 위한 본 발명은 먼저 하부금형이 안착되는 하부다이를 가공할 때 하부금형의 안착위치를 조금 벗어난 위치에 2개소에 두 개의 받침블럭을 일체로 형성하고, 각 받침블럭에는 정밀하게 직각으로 가공된 직각밀착면을 형성하며, 하부금형 측부에 상기 직각밀착면에 밀착되는 밀착돌출부를 구성하는 것을 특징으로 한다.In order to achieve the above object, the present invention first forms two support blocks integrally at two locations in a position slightly out of the seating position of the lower mold when processing the lower die on which the lower mold is seated, and each support block is precisely formed. It forms a right-angled contact surface processed at a right angle, and it is characterized in that the lower mold side comprises a close contact protrusion that is in close contact with the right-angle contact surface.

따라서 이와 같이 하부다이와 하부금형을 가공한 다음, 조립시에는 하부금형의 양측 밀착돌출부가 하부다이의 직각밀착면에 밀착되도록 밀어 넣으면 정확히 하부금형의 위치가 안착되도록 한 것이 특징이다.Therefore, after processing the lower die and the lower mold as described above, when assembling, push the contact protrusions on both sides of the lower die in close contact with the orthogonal contact surface of the lower die, so that the position of the lower mold is accurately settled.

상기와 같은 본 발명에 의하면 고정을 위한 받침블럭과 직각밀착면 및 밀착돌출부 등의 가공부위가 하부금형의 외부와 하부다이의 측면에 노출되는 것이므로 가공작업이 편리하고 신속하게 이루어질 수 있으며, 하부금형을 하부다이에 조립하는 작업시 하부금형을 하부다이 상면의 측방향에서 밀어넣으면서 밀착시켜주기만 하면 정확한 위치로 설정되므로 매우 편리하고 신속하게 되며, 하부금형을 하부다이로부터 분리할 때도 고정볼트를 제거하고 측방향으로 밀어주기만 하면 분리가 완성 되는 등 작업의 생산성과 효율성을 극대화할 수 있는 발명인 것이다.According to the present invention as described above, since the processing blocks such as the support block for fixing and the right-angle contact surface and the contact protrusions are exposed on the outside of the lower mold and the side surfaces of the lower die, the machining operation can be conveniently and quickly performed, and the lower mold When assembling to the lower die, it is very convenient and quick since it is set to the correct position by pushing the lower mold in the lateral direction of the upper surface of the lower die, and it is very convenient and quick. When removing the lower mold from the lower die, remove the fixing bolt and It is an invention that can maximize the productivity and efficiency of work such as completion of separation by simply pushing in the lateral direction.

이하 본 발명을 구현하기 위한 바람직한 구성 실시 예를 첨부된 도면에 의거 상세히 살펴보면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 대상으로 하는 프레스 성형장치는 베이스(10) 위의 하부다이(20)에 하부금형(21)을 설치하고 그 상부 이격된 위치에 설치되는 상부다이(30) 저면에 상부금형(31)을 설치한 다음, 하부다이(20) 위에 소재를 얹고 상부다이(30)를 하강시켜 소재를 성형하거나 절단하는 것이다.The press molding apparatus targeted for the present invention is to install the lower mold 21 on the lower die 20 on the base 10 and the upper die 30 on the bottom of the upper die 30 which is installed in the upper spaced apart position. After installing, the material is placed on the lower die 20 and the upper die 30 is lowered to form or cut the material.

본 발명은 먼저 프레스 성형장치의 하부금형(21)을 안착시키기 위한 하부다이(20)를 가공할 때 하부금형(21)의 안착위치를 감안하여 하부금형(21)의 외형을 조금 벗어난 위치에 2개소에 두 개의 받침블럭(22)을 하부다이(20)에 일체로 형성하는데, 각 받침블럭(22)에는 정밀하게 직각으로 가공된 직각밀착면(23)을 형성하였다.In the present invention, when processing the lower die 20 for seating the lower mold 21 of the press forming apparatus first, considering the seating position of the lower mold 21, a position slightly out of the outer shape of the lower mold 21 2 Two supporting blocks 22 are integrally formed on the lower die 20 at the location, and right-angled contact surfaces 23 are formed at each right angle at the right angles of the supporting blocks 22.

하부금형(21)에는 측부에 상기 받침블럭(22)의 직각밀착면(23)에 밀착되면서 하부금형(21)의 설치위치가 정확히 완성되도록 밀착돌출부(24)를 구성하는데 일측 받침블럭(22)에 밀착되는 밀착돌출부(24)는 정확히 직각을 이루도록 2개를 구성하고 다른 한쪽의 받침블럭(22)에 밀착되는 밀착돌출부(24)는 1개를 구성하였다.The lower mold 21 is configured to be in close contact with the orthogonal contact surface 23 of the supporting block 22 on the side, so that the mounting protrusion 24 is formed so that the installation position of the lower mold 21 is accurately completed. The close contact protrusions 24 that are in close contact with each other are configured to form a right angle, and the close contact protrusions 24 that are in close contact with the other support block 22 are one.

이와 같이 하부다이(20)와 하부금형(21)을 가공한 다음, 조립시에는 하부다이의 위에 하부금형(21)을 얹고 하부금형(21)의 양측 밀착돌출부(24)가 하부다이의 직각밀착면(23)에 밀착되도록 밀어 넣으면서, 일측 받침블럭(22)의 직각밀착면(23)에는 직각을 이루는 두 개의 밀착돌출부(24)가 모두 완전히 밀착되게 하고 일측 받침블럭(22)의 직각밀착면(23)에는 하나의 밀착돌출부(24)만 완전히 밀착되도록 하면, 정확히 하부금형(21)의 위치가 안착이 되고 이후 볼트 등의 고정수단을 통하여 완전히 고정하는 작업을 하면 된다.After processing the lower die 20 and the lower mold 21 in this way, upon assembly, the lower die 21 is placed on the lower die and the contact protrusions 24 on both sides of the lower die 21 are at right angles to the lower die. Pushing so as to be in close contact with the surface 23, the right contact surface 23 of the one side support block 22, the two contact protrusions 24 forming a right angle are all in close contact, and the right contact surface of the one side support block 22 If only one contact protrusion 24 is completely in contact with (23), the position of the lower mold 21 is settled exactly, and then it is necessary to completely fix it through a fixing means such as a bolt.

금형의 수정이나 교체 등의 작업을 하기 위해 하부금형(21)을 분리할 때도 볼트 등의 고정수단을 제거한 후 옆으로 밀어주기만 하면 하부금형(21)이 하부다이(20)로부터 분리되므로 작업이 편리하고 다시 조립할 때도 상기와 같이 편리하게 조립할 수 있게 된다.Even when removing the lower mold 21 for the purpose of modifying or replacing the mold, simply remove the fixing means such as bolts and push it to the side, so that the lower mold 21 is separated from the lower die 20, so the work is convenient. And when assembling again, it is possible to assemble conveniently as described above.

상기에서 받침블럭(22)의 위치와 직각밀착면(23)의 방향 그리고 밀착돌출부(24)의 위치는 프레스 작업시 성형 물품의 구조를 감안하고 하부금형이 측방향으로 하중을 받는 상태를 감안하여 측방향 하중을 받는 방향을 받쳐주는 위치와 방향으로 구성하면 성형시의 정밀도 향상과 하부금형의 수명 연장에도 큰 도움이 된다.In the above, the position of the support block 22, the direction of the right-angled contact surface 23 and the position of the contact protrusions 24 are taken into account in the structure of the molded article during the press operation and in consideration of the state in which the lower mold is loaded in the lateral direction. It is very helpful to improve the precision during molding and to extend the life of the lower mold by constructing it in a position and direction that supports the direction under the lateral load.
