Description

유압을 이용한 입체성형물의 제조방법 및 장치{the manufacturing process and equipment of a forming goods}Method and apparatus for manufacturing a three-dimensional molded object using hydraulic pressure

본 발명은 유압을 이용한 입체성형물의 제조방법 및 장치에 관한 것으로, 보다 상세하게는 프레스 등을 이용하여 1차성형물을 제조 성형한 후, 상기 1차성형물의 외주면에 각종 입체돌부를 형성함에 있어서 매우 신속간편하면서도 불량없이 정확하게 성형할 수 있게 함으로서, 생산성과 상품성을 극대화시킬 수 있게 하기 위한 것이다.The present invention relates to a method and apparatus for producing a three-dimensional molded article using hydraulic pressure, and more particularly, after manufacturing and molding a primary molded product by using a press or the like, forming various three-dimensional protrusions on the outer circumferential surface of the primary molded product. By making it easy to mold quickly and without defects, it is intended to maximize productivity and productability.

주지된 바와 같이 각종 금속판재를 프레스성형하여 입체용기 등을 제조성형하는 방법은 주지된 사실이다.As is well known, a method of manufacturing and molding a three-dimensional container by press molding various metal sheet materials is well known.

일예를 들어 금속판재로 된 사각체의 용기 또는 기계및 전자부품등을 프레스로 성형할 때는 소정의 프레스금형을 프레스에 장착한뒤 용기 또는 기계나 전자부품 등의 특성에 따라 1회 또는 다수회의 프레스공정을 거쳐 제작하게 되며, 이 경우 용기의 깊이가 어느정도 깊더라도 프레스작업전에 신축률을 감안하여 금속판재의 두께를 선택하면 성형에 전혀 문제가 없다.For example, when forming a rectangular plate made of a metal plate, or a machine or an electronic part by press, a predetermined press mold is mounted on the press, and then presses are made one or more times depending on the characteristics of the container or machine or electronic part. It is produced through the process, in this case, even if the depth of the container to some extent, if the thickness of the metal sheet is selected in consideration of the expansion rate before the press work there is no problem in molding at all.

그러나, 상기와 같은 용기나 기계 및 전자부품의 외주면에 일종의 방열돌부처럼 돌출부나 요부를 깊게 형성하는 경우는 프레스로 완제품을 성형한다는 것이 불가능하다.However, in the case of forming a protruding portion or a recessed portion deeply on the outer circumferential surface of the container, machine or electronic component as described above, it is impossible to mold the finished product by pressing.

따라서 이 경우에는 용기의 바닥변과 벽면을 따로 분리하여 각각 성형한뒤 벽면을 사각으로 절곡하고, 이어서 바닥면을 절곡된 벽면의 끝단에 일치시킨다음 용접을 행하는 방법 외에는 다른 대안이 없게 된다.Therefore, in this case, there is no alternative other than the method of separating the bottom side and the wall of the container separately, forming each of them, bending the wall to a square, and then matching the bottom to the ends of the bent wall and then performing welding.

그러나 위와 같이 외부면에 입체돌출부나 요부를 깊게 형성할 경우에는 프레스작업공정은 물론 절곡공정, 용접공정등으로 인하여 공정이 과다하게 되고, 불량발생률이 매우 높게 되며, 이에 따라 제조원가가 크게 상승하게 됨은 물론 생산성이 크게 떨어져서 원가상승이 야기되면서도 상품가치는 그만큼 더 떨어지게 되는 폐단이 따르게 된다.However, when the three-dimensional protrusions or recesses are deeply formed on the outer surface as described above, the process becomes excessive due to the press working process, the bending process, the welding process, and the like, and the incidence of defects is very high, thereby greatly increasing the manufacturing cost. Of course, productivity will drop so much that cost rises, but product value falls further.

특히 근자에 와서는 각종 전자제품이나 기계제품등에 방열의 효과를 높이기 위한 각종 부품들이 개발되고 있으며, 이러한 부품들 중의 일부는 압출이나 사출에서 해결할 수 없는 구성을 갖춘 부품들이 많다.In particular, in recent years, various parts have been developed to enhance the effect of heat dissipation on various electronic products and mechanical products, and some of these parts have components that cannot be solved by extrusion or injection.

따라서 이를 해결할 수 있는 방법의 개발이 매우 시급한 실정이다.Therefore, it is very urgent to develop a method to solve this problem.

본 발명은 상기한 종래의 제반 문제점을 감안하여 발명된 것으로, 특히, 사각이나 원형, 또는 삼각등을 비롯한 다각의 용기 형태를 갖추면서, 외주벽면에 방열돌부를 비롯한 각종 입체문양이나 형상등의 입체돌출부가 형성된 성형물을 제조함에 있어서, 1차적으로는 프레스를 이용하여 1차 성형물을 제조하고, 이어서 유압을 이용하여 완성품인 2차 성형물을 제조함으로서 제조에 따른 공정을 크게 절감하고 제조시 불량이 발생될 염려가 극히 적으며, 생산성향상과 상품성을 높일 수 있는 방법및 장치를 제공하려는데 발명의 목적이 있다.The present invention has been invented in view of the above-described conventional problems, and in particular, having a shape of a polygonal container including a square, a circle, or a triangular shape, a three-dimensional shape such as various three-dimensional patterns or shapes including heat dissipation protrusions on the outer circumferential wall thereof. In manufacturing a molded article with protrusions, a primary molded product is first manufactured by using a press, and then a secondary molded product, which is a finished product, is manufactured by using hydraulic pressure, thereby greatly reducing the manufacturing process and generating defects in manufacturing. An object of the present invention is to provide a method and apparatus that can be extremely low, and to improve productivity and increase the marketability.

본 발명은 사각, 원형, 삼각, 등등을 비롯한 다각의 입체용기 또는 부품의 외주면에 유압을 이용하여 다수의 방열돌기나 입체돌부를 일체로 성형하는 방법을 제공하기 위한 것이며, 프레스를 이용하여 1차 성형물을 제조한뒤, 상기 1차성형물에 다시 유압을 이용하여 소정의 입체문양이나 돌기, 돌부 등과 같은 입체돌부를 형성함으로서 프레스작업만으로는 생산이 불가능하거나 지나치게 공정이 많고 복잡할 수 밖에 없는 경우에 매우 효과적으로 실시할 수 있는 방법이다.The present invention is to provide a method for integrally forming a plurality of heat dissipation protrusions or three-dimensional protrusions by using hydraulic pressure on the outer peripheral surface of the polygonal three-dimensional container or parts, including square, circle, triangular, etc. After the molding is manufactured, it is possible to produce a three-dimensional protrusion such as three-dimensional patterns, protrusions, and protrusions by using hydraulic pressure on the primary molding again. It can be done effectively.

특히 본 발명에서는 프레스 등에 의해 제조성형된 1차성형물의 내부에 소정량의 유량이 소정의 압력으로 직접공급되게 함으로써 1차 성형물의 내부에 매우 고른 압력으로 유압이 작용하게 할 수 있으며, 이는 곧 기구적인 부분에서 해결하기 어려운 성형물의 균일한 두께 유지가 가능해지고, 더불어 매우 세밀한 무늬나 제법 긴 돌출부 등도 안정적으로 형성할 수 있게 된다.In particular, in the present invention, by supplying a predetermined amount of flow rate directly to a predetermined pressure inside the primary molded product manufactured by a press or the like, the hydraulic pressure can be operated at a very even pressure inside the primary molded product, which is a mechanism It is possible to maintain a uniform thickness of the molding which is difficult to solve in the general part, and also to form a very fine pattern or a protruding long process stably.

이하 본 발명의 입체성형물의 제조방법 및 장치에 대하여 순서대로 설명하면 다음과 같다.Hereinafter, the manufacturing method and apparatus of the three-dimensional molded article of the present invention will be described in order.

먼저 프레스를 이용하여 입체적이면서 외주면이 민자인 1차성형물(1)을 제조한다. (여기서 입체적이라는 표현은 대부분의 용기처럼 내부에 공간부가 형성되고, 각종 유체나 분말 등을 안정적으로 담을 수 있는 구성으로 된 것을 말하며, 그 형상은 규칙적인 것이든 불규칙적인 것이든 관계없다)First, by using a press to produce a three-dimensional primary molding (1) of the outer peripheral surface is private. (Three-dimensional expression here refers to a structure in which a space portion is formed inside, like most containers, and can stably contain various fluids or powders. The shape may be regular or irregular)

이어서 상기 1차성형물(1)을 유압금형에 장착한뒤 유압을 이용하여 1차 성형물의 외주면에 방열돌부 또는 각종 문양 등의 입체돌부(2)를 형성한다.Subsequently, the primary molded product 1 is mounted on a hydraulic mold, and then three-dimensional protrusions 2 such as heat dissipation protrusions or various patterns are formed on the outer circumferential surface of the primary molded product using hydraulic pressure.

상기와 같은 입체돌부(2)를 형성하기 위한 유압금형(10)은 평면상에서 성형부의 중심으로 전후 이송하는 복수개의 슬라이드식 분할금형(3)과, 수직방향으로 승강하면서 상기 분할금형(3)이 중앙부로 모아졌을 때 상부를 밀폐시켜줌과 동시에 소정의 유압을 공급하도록 된 승강식 캡금형(4)으로 구성된다.Hydraulic mold 10 for forming the three-dimensional protrusion (2) is a plurality of slide-type split mold (3) for conveying back and forth to the center of the molding portion on a plane, and the divided mold (3) while lifting in the vertical direction It is composed of a liftable cap mold 4 which is configured to seal the upper part and collect a predetermined hydraulic pressure when gathered to the center part.

상기한 슬라이드식 분할금형(3)은 유압 또는 공압을 이용한 실린더나 모터등을 이용한 기계적인 이송수단을 이용하여 이송시킬 수 있고, 이송시에는분할금형(3)의 이송위치에 맞춰 바닥에 복수개의 레일을 설치하여 분할 금형(3)이 상기 레일을 타고 이송할 수 있게 구성하는 것이 바람직하다.The slide-type divided mold (3) can be transferred using a mechanical conveying means such as a cylinder or a motor using hydraulic or pneumatic, and at the time of conveying a plurality of slides on the bottom in accordance with the transfer position of the divided mold (3) It is preferable to install the rail so that the split die 3 can be transported on the rail.

또, 상기 분할금형(3) 각각의 내측면에는 성형물의 외주면에 형성시키고자 하는 입체돌부(2)의 모양을 감안하여 입체요부(31)를 갖추어야 하고, 분할금형(3)의 수는 제조하고자 하는 성형물의 특성과 입체돌부(31)의 형상 모양에 따라 결정되어야 한다.In addition, the inner surface of each of the divided mold (3) should be provided with a three-dimensional recess (31) in consideration of the shape of the three-dimensional protrusion (2) to be formed on the outer peripheral surface of the molding, the number of the divided mold (3) To be determined according to the shape of the molding and the shape of the three-dimensional protrusions (31).

또, 상기한 분할금형(3)은 각각이 동시에 성형부에 모아졌을 때 분할금형(3) 각각이 서로 맞닿아 밀폐되게 하여야 하고, 이러한 구성은 분할금형(3)이 인접하는 타 분할금형(3)과 서로 밀착되는 부분에 밀폐용 패킹을 비롯한 누유방지수단을 장착하면 된다.In addition, the above-mentioned dividing mold (3) should be such that each of the dividing mold (3) is in contact with each other and sealed when each of them is collected at the same time in the molding portion, this configuration is the other dividing mold (3) adjacent to the dividing mold ) And leakage prevention means, including sealing packing, to be in close contact with each other.

이때, 상기한 누유방지수단은 성형물의 형상 모양 등의 특성에 따라 설치위치가 달라질수 있어 본 발명의 도면에서는 구체적인 도시를 생략한다.At this time, the leakage preventing means described above may be changed depending on the characteristics of the shape, shape, etc. of the molding, so that the specific illustration is omitted in the drawings of the present invention.

또, 실제 작업에 있어서 분할금형(3)을 성형부로 이송시킬 때는 이보다 먼저 프레스로 성형된 1차 성형물(1)을 성형부에 안착시킨 상태에서 이송시켜야 하고, 분할금형(3)이 성형부로 이송되어 모아진 후에는 승강식 캡금형(4)이 하강하여 모아진 분할금형(3) 상부에 접속되게 하는데, 이때 분할금형(3)과 승강식 캡금형(4)의 연접부에는 미세한 틈도 발생되어서는 안된다.In the actual work, when the divided mold 3 is transferred to the molding part, the first molded product 1 formed by pressing must be transferred to the molding part, and the divided mold 3 is transferred to the molding part. After being collected, the liftable cap mold 4 is lowered and connected to the upper part of the divided mold 3, and at this time, the gap between the split mold 3 and the liftable cap mold 4 is also generated. Can not be done.

다시 말하면, 상기 승강식 캡금형(4)의 저면 가장자리, 특히 분할금형(3)과 맞닿는 부분에 누유방지용 패킹(도시하지 않음)이 장착되어야 한다는 것이다.In other words, a leakage preventing packing (not shown) should be mounted at the bottom edge of the liftable cap mold 4, in particular, at a portion contacting the split mold 3.

또, 상기 승강식 캡금형(4)에는 유압모터(도시하지 않음)에 의해 소정량의유량이 소정의 압력으로 공급될 수 있도록 유압공급호스(5)가 장착되고, 성형후에는 공급된 유량이 모두 배출될 수 있도록 유압배출호스(6)도 함께 장착된다.In addition, the lifting cap die 4 is equipped with a hydraulic supply hose 5 so that a predetermined amount of flow can be supplied at a predetermined pressure by a hydraulic motor (not shown). The hydraulic discharge hose 6 is also mounted so that both can be discharged.

따라서 유압공급호스(5)를 통해 유압금형(10)내부로 소정의 유량이 소정의 압력으로 공급되면 유압금형(10) 내에서는 사방으로 균일한 압력으로 1차 성형물(1)의 벽면을 분할금형(3)으로 밀어내게 되고, 이러한 압력에 의해 분할금형(3)에 형성된 입체요부(31)의 형상대로 1차 성형물(1)의 외주벽면이 밀려 들어가게 되는 것이며, 이어서 유압배출호스(6)를 통하여 성형물 내부에 투입된 유량을 제거한뒤 승강식 캡금형(4)을 상승시키고 뒤이어 분할금형(3)을 후방으로 이송시키면 외주면에 입체돌출부(2)가 형성된 2차성형물(1')이 완성되는 것이다.Therefore, when a predetermined flow rate is supplied into the hydraulic mold 10 through the hydraulic supply hose 5 at a predetermined pressure, the hydraulic mold 10 divides the wall surface of the primary molding 1 into a uniform pressure in all directions. The outer peripheral wall surface of the primary molded product 1 is pushed into (3) in the shape of the three-dimensional recesses 31 formed in the split mold 3 by this pressure, and then the hydraulic discharge hose 6 is pushed. After removing the flow rate injected into the molding through the lifting cap die (4) is raised and then transfer the divided mold (3) to the rear, the secondary molding (1 ') having a three-dimensional protrusion (2) formed on the outer peripheral surface is completed. .

한편, 알루미늄이나 동합금 등을 비롯한 각종 철금속이나 비철금속판재를 이용하여 상기와 같이 유압금형에 의해 외주면에 제법 길게 방열돌부와 같은 입체 돌부(2)를 가진 2차성형물(1')을 성형할 때는 상기 입체돌부(2)의 돌출길이나 크기 수량등에 따라 적어도 성형과정에서 발생하는 신축률을 감안하여 원재료의 두께도 사전에 적절한 두께로 설정하여야 하며, 이러한 선택은 동업계의 자라면 누구나 예측 가능하기에 더이상의 설명은 생략한다.On the other hand, when forming a secondary molding (1 ') having three-dimensional protrusions (2) such as heat dissipation protrusions on the outer circumferential surface by a hydraulic mold as described above using various ferrous metals or nonferrous metal plate materials, such as aluminum, copper alloy, etc. The thickness of the raw material should also be set to an appropriate thickness in advance, at least in consideration of the elasticity rate generated during the molding process according to the protruding length or the size and quantity of the three-dimensional protrusions 2, and such a selection can be predicted by anyone in the industry. The further explanation is omitted.

이하 실시예를 통하여 보다 상세하게 설명한다.It will be described in more detail through the following examples.

<실시예><Example>

제 1 공정; 1차 성형물 성형공정First process; Primary molding process

프레스를 통하여 상부가 개방된 사각 용기체를 성형하여 1차 성형물(1)을 완성한다.The primary molded product 1 is completed by molding a rectangular container body having an open upper portion through a press.

제 2공정: 2차 성형물 성형공정2nd process: 2nd molding process

제1공정을 통하여 제조된 1차 성형물을 유압금형(10)의 성형부에 안착시키고, 내측면에 다수의 입체요부(31)를 형성하여서 된 다수개의 분할금형(3)을 가동시켜 1차 성형물(1)을 지지시킨뒤, 승강식 캡금형(4)을 하강시켜 성형부로 모아진 분할금형(3)의 상단부에 접속되면서 동시에 1차성형물(1)의 상부 개방부에 밀착되어 밀봉되게 한 다음 유압공급호스(5)로 1차 성형물(1) 내부에 일정한 압력으로 유량을 공급시킨다.The primary molded product manufactured by the first process is seated on the molding part of the hydraulic mold 10, and a plurality of divided molds 3 formed by forming a plurality of three-dimensional recesses 31 on the inner side are operated to form the primary molded product. After supporting (1), the elevating cap mold (4) is lowered to be connected to the upper end of the divided mold (3) collected by the molding part, and at the same time to be in close contact with the upper opening of the primary molding (1) to be sealed. The supply hose 5 supplies a flow rate at a constant pressure inside the primary molding 1.

상기와 같이 일정압력의 유량이 1차 성형물(1) 내부에 공급되면 유압에 의해 1차 성형물의 외주면이 분할금형(3)에 형성된 입체요부(31)로 밀려들어가게 되며, 완전하게 입체요부(31)로 1차 성형물의 외주면이 밀려들어간 다음에는 유압배출호스(6)를 통하여 1차성형물(1) 내부에 차 있던 유량을 배출한 다음 승강식 캡금형(4)을 상승시키고, 이어서 분할 금형(3)을 본래의 위치로 복귀시켜 2차성형물(1')을 얻는다.When the flow rate of the constant pressure is supplied into the primary molding 1 as described above, the outer peripheral surface of the primary molding is pushed into the solid recess 31 formed in the divided mold 3 by hydraulic pressure, and the solid recess 31 is completely. After the outer circumferential surface of the primary molded product is pushed into), the flow rate filled inside the primary molded product 1 is discharged through the hydraulic discharge hose 6, and then the lifting cap die 4 is raised, and then the divided mold ( 3) is returned to its original position to obtain the secondary molding 1 '.

이와 같은 방법을 통하여 얻은 2차 성형물(1')은 분할금형(3)의 내측 벽면에 형성된 입체요부(31)의 형상에 따라 외주면에 일정한 간격으로 다수의 입체돌부(2)가 형성되었으며, 2차 성형물(1')의 외관은 압력불균형으로 인한 주름이나 변형없이 매우 깔끔하고 미려단정하게 형성 되었다.According to the shape of the three-dimensional recessed portion 31 formed on the inner wall surface of the divided mold 3, the secondary molded product 1 'obtained through the above method was formed with a plurality of three-dimensional protrusions 2 at regular intervals on the outer peripheral surface. The exterior of the primary molded article 1 'was formed very neatly and neatly without wrinkles or deformation due to pressure imbalance.

한편, 상기 실시예의 경우는 상부가 개방된 사각 입방체 용기의 측면부분에 세로방향으로 다수의 입체돌부(2)를 일정한 간격으로 다수 돌출형성시킨 구성이며, 이때 입체돌부(2)의 최대 돌출길이는 분할금형(3)에 형성된 입체요부(31)의 깊이와더불어 1차 성형물(1)의 두께및 재질등에 따라 달라질수 있다.On the other hand, in the case of the embodiment is a configuration in which a plurality of three-dimensional protrusions (2) protruding at regular intervals in the longitudinal direction on the side portion of the rectangular cube container with an open top, wherein the maximum protrusion length of the three-dimensional protrusions (2) is In addition to the depth of the three-dimensional recesses 31 formed in the divided mold (3) may vary depending on the thickness and the material of the primary molding (1).

또, 상기한 유압금형(10)은 분할금형(3)과 승강식 캡금형(4)으로 구성되고, 상기 분할금형(3)은 금형 내측면에 소정의 형상으로 각종 입체무늬 등이 음각 형성된 입체요부(31)가 형성되며, 또, 성형물의 형상과 모양에 따라 분할금형(3)의 형상과 갯수가 정해지게 되고, 승강식 캡금형(4)의 경우도 상기 다수의 분할금형(3)이 조립되었을 때 상부에 안정적으로 안착될 수 있도록 구성하여야 한다.In addition, the hydraulic mold 10 is composed of a divided mold (3) and a lifting cap mold (4), the divided mold (3) is a solid shape in which various three-dimensional patterns and the like are engraved in a predetermined shape on the inner surface of the mold The recess 31 is formed, and the shape and number of the divided molds 3 are determined according to the shape and the shape of the molding. In the case of the liftable cap mold 4, the plurality of divided molds 3 When assembled, it should be constructed so that it can be stably seated on the top.

따라서 분할금형(3)에 형성되는 각종 모양의 입체요부(31)나 분할금형(3)의 형상, 승강식 캡금형(4)의 형상등은 성형하고자 하는 성형물에 따라 변화가 있게 마련이므로 이러한 변화는 당연히 본 발명의 권리범위에 당연히 속한다 할 것이다.Therefore, the shape of the three-dimensional recesses 31, the divided mold 3, and the shape of the liftable cap mold 4 having various shapes formed on the divided mold 3 may vary depending on the molding to be molded. Naturally it will belong to the scope of the present invention.

또한, 본 발명을 실시함에 있어서, 유압뿐만 아니라 수압도 이용할 수 있으며, 이와 같이 수압을 이용하는 것 역시 본 발명의 권리범위에 당연히 속한다 하겠다.In addition, in the practice of the present invention, not only hydraulic pressure but also hydraulic pressure may be used, and thus, the use of hydraulic pressure is naturally within the scope of the present invention.
