Description

신선기{drawing machine}Drawing machine

본 발명은 신선기에 관한 것으로, 보다 상세하게는 성형공을 형성하는 한 쌍의 그루브(groove) 롤러의 상면에 형성되는 그루브의 형상을 단순하게 함으로써 직경이 큰 선재의 인발을 용이하게 할 수 있으므로 작업성이 향상되고 상품의 가치를 높일수 있어 상품성을 증대시킬 수 있는 신선기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drafting machine, and more particularly, to a drafting machine capable of facilitating drawing of a wire rod having a large diameter by simplifying the shape of a groove formed on the upper surface of a pair of groove rollers forming a forming hole Which can enhance the merchantability by improving the quality and the value of the merchandise.

일반적으로 봉재나 관재의 인발은 통상적인 인발기로 행하며, 선재는 권동이 붙은 신선기를 사용하여 이루어진다.In general, the drawing of the rods or pipes is carried out by a conventional drawing machine, and the drawing is carried out by using a drawing machine with a winding.

상기 신선기는 완성된 선재의 직경, 윤활방식, 구조양식에 따라 다음과 같이 분류되는데 먼저, 선재의 직경에 따라 분류해 보면, 3mm 이상의 굵은 선용, 0.5 내지 3mm의 중선용, 0.1 내지 0.5mm의 세선용, 0.1mm 이하의 극세선용 신선기 등으로 분류되는데 본 발명에 적용되는 10mm 이상의 선재를 형성시키는데 적용된다.According to the diameter of the wire rod, the wire rod is classified into three types: thick wire of 3 mm or more, wire of 0.5 to 3 mm, wire of 0.1 to 0.5 mm And an ultra fine wire drawing machine of 0.1 mm or less, and is applied to forming a wire material of 10 mm or more, which is applied to the present invention.

또한, 윤활방식에 따라, 고체윤활제에 의한 건식, 액상의 윤활제가 사용되나 캡스탄(capstan)에 윤활이 되지 않는 반습식, 다이 및 캡스탄에 액상의 윤활제가 사용되는 습식 신선기 등으로 분류된다.In addition, according to the lubrication method, a dry or liquid lubricant is used as a solid lubricant, but the capstan is classified into a semi-wet lubricant not lubricated, a die and a wet type drawer in which capstan lubricant is used as a liquid lubricant.

그리고 마지막으로, 구조양식에 따라, 단식과 연속식 신선기로 분류되고, 단식과 연속식 신선기는 더 세부적으로 분류가 가능하며, 단식 신선기의 주요부는 소재를 성형하는 그루브롤러, 다이받이, 및 권동 등으로 이루어져 있고, 연속식 신선기는 수 개의 다이를 직렬로 배치하여 연속적으로 신선작업을 할 수 있도록 한 것으로, 단식 신선기와 마찬가지로 그루브(grove) 롤러, 수 개의 다이받이, 중간 권동이라고도 하는 캡스탄, 및 권동으로 그 주요부를 이루고 있다.Finally, according to the structural style, it is categorized into fast and continuous type drawing machine, and single and continuous type drawing machine can be classified in more detail. The main part of the single drawing type drawing machine is a groove roller, die receiver, And a continuous type drawing machine is a machine in which a plurality of dies are arranged in series to continuously perform a drawing operation. Like the single drawing machine, a groove roller, a plurality of die bases, a capstan, It is the main part of Gwangdong.

또한, 성형된 선재가 캡스탄 상에서 미끄러지는 슬립형과 미끄러지지 않는 넌슬립식 신선기로도 분류될 수 있다.Also, the formed wire rod can be classified into slip-type slip-on non-slip non-slip type sliders on capstan.

이와 같이 분류되는 상술한 신선기는 소재가 그루브 롤러 사이를 통과되면서 소재의 직경이 줄어들고 권동에 의해 잡아당겨져 권동에 감겨져 보관되는 형식으로 작업이 마무리된다.The above-described drawing machine to be classified in this manner is finished in such a manner that the diameter of the material is reduced while the material passes between the grooved rollers, is pulled by the winding, is wound around the winding, and is stored.

이렇게 성형된 소정 직경을 가진 선재는 어느 정도 이상의 진원도가 확보되어야 선재로써의 사용이 가능하며 이때 진원도란 원형부분의 기하학적 원에서의 변형의 크기를 말하며 KS에서는 원형부분을 2개의 동심의 기하학적 원으로 둘러쌌을 때, 양원의 간격이 최소가 될 경우의 양원의 반경의 차로 나타낸다고 정해져 있다.The formed wire having a predetermined diameter should have a certain degree of circularity to be used as a wire rod. The roundness is the size of the deformation in the geometric circle of the circular portion. In KS, the circular portion is divided into two concentric geometric circles And is defined as a difference between the radii of the two circles when the interval between the two circles becomes minimum when the two circles are enclosed.

상기와 같은 통상의 신선기를 보면 그 외형을 이루는 하우징 내부에 한 쌍씩 짝지워진 그루브 롤러가 구비되고, 성형될 소재가 상기 그루브 롤러가 이루는 성형공을 통과하면서 소정 크기의 직경을 가진 선재로 성형되게 된다.The conventional drawing machine as described above is provided with a pair of grooved rollers paired with each other in a housing forming the outer shape and the material to be formed is formed into a wire rod having a predetermined diameter while passing through a molding hole formed by the groove roller .

보통, 선재의 길이별 직경 편차를 줄이기 위해 복수의 그루브 롤러가 배치되고, 마지막 그루브 롤러의 뒤에 설치된 권동에 의해 소재가 인출되며, 상기 그루브 롤러 간의 위치 조정은 조정 레버에 의해 수동으로 이루어진다.Normally, a plurality of groove rollers are disposed to reduce the diameter deviation of the wire rod, and the material is drawn out by a winding provided behind the last groove roller, and the position adjustment between the groove rollers is manually performed by the adjustment lever.

그러나 상기와 같은 종래기술에 따른 신선기에 있어서 세선용일 경우에는 상기 그루브 롤러의 상부에 형성된 그루브는 별문제가 없이 용이하게 성형 인발이 되나 직경이 8mm 이상이 되는 선재의 인발인 경우에는 그 성형 인발이 용이하지 못하여 사람이 직접 성형을 하는 경우가 많아 작업성이 저하되는 문제점을 내포하고 있었다.However, in the case of the above-mentioned prior art drawer for fine wire, the groove formed on the upper portion of the groove roller can be easily drawn out without any problem, but when the wire rod having a diameter of 8 mm or more is drawn, It is difficult to make the molding directly, so that the workability is lowered.

따라서 본 발명은 상기와 같은 종래 기술에 따른 문제점을 해결하고자 창안한 것으로, 본 발명의 목적은 성형공을 형성하는 한 쌍의 그루브 롤러의 상면에 형성되는 그루브의 형상을 단순하게 함으로써 직경이 큰 선재의 인발을 용이하게 할 수 있으므로 작업성이 향상되고 상품의 가치를 높일수 있어 상품성을 증대시킬 수 있는 신선기를 제공하는 데 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a grooved roller having a large diameter by forming a groove on a top surface of a pair of grooved rollers, So that the workability can be improved and the value of the product can be increased, thereby providing a new machine that can increase the merchantability.

이러한 상기 목적은 본 발명에 의해 달성되며, 본 발명의 일면에 따라, 서로 맞물려 소재를 성형하는 성형공이 다수개 형성되고, 외주부에 각각 암, 수의 단차진 형상을 이루어 서로의 위치를 구속하는 한 쌍의 그루브 롤러가 다수개 배열된 소재 성형부와, 상기 소재 성형부를 작동시키는 모터로 이루어지는 신선기에 있어서, 상기 한 쌍의 그루브 롤러의 상면에 형성되는 그루브의 직경은 시작과 끝이 서로 다르게 형성되되 그 성형공의 크기는 시작과 끝이 원형이며, 상기 한 쌍의 그루브 롤러가 서로 맞물려 형성되는 성형물은 길다란 원뿔대인 것을 특징으로 한다.According to an aspect of the present invention, there is provided a method of manufacturing a metal mold, comprising: forming a plurality of molding holes for forming a workpiece by engaging each other and forming a stepped shape in an outer periphery of each of the molds, Wherein a diameter of a groove formed on an upper surface of the pair of groove rollers is different from a diameter of a groove formed on the upper surface of the pair of groove rollers, The mold is characterized in that the start and end are circular in shape and the molded article in which the pair of groove rollers are meshed with each other is a long truncated cone.
