Abstract

A packing according th the present invention has a cross section as round shape and the entire round shape. First a aluminium pipe is manufactured in the round shape and given dimension, and which is fixed by the chuck(2) of the lathe. The half circle of the aluminium pipe is processed by means of a outside diameter shaping bite(4) and a inside diameter shaping bite(4A) respectively. The advantages of the packing have that the aluminium pipe is shaped by the bites so that product size is uniform, and that shaping and cutting is taken place at the same time so that the working hours is shortened and working process is reduced and mass production is able to possible.

본 발명은 팩킹 단면의 모양이 원이고, 전체형상 또한 원형인 팩킹의 제조방법에 관한 것이다.The present invention relates to a method for producing a packing in which the shape of the packing cross section is a circle and the overall shape is also circular.

팩킹의 기능은 밀폐성 확보에 있고, 그 기능으로 인하여 산업전반에 다양한 형태로 사용되어지고 있는 실정이다.The function of the packing is to ensure the sealing, and due to its function is being used in various forms throughout the industry.

본 발명은 특히, 고온, 고압 상태인 폴리머, 모노머의 원사중합공정에 사용되는 단면의 모양이 원이고, 전체형상 또한 원형인 팩킹(이하, 팩킹)에 관한 것이다.In particular, the present invention relates to a packing in which the cross-sectional shape used in the yarn polymerization process of polymers and monomers at high temperature and high pressure is a circle, and the overall shape is also circular.

종래 팩킹의 제작방법과 그 폐단을 살펴보면 아래와 같다.Looking at the manufacturing method and the closing of the conventional packing as follows.

먼저 종래의 팩킹 제작공정을 살펴보면, 다음과 같다.Looking at the conventional packing manufacturing process as follows.

첫째, 선재를 원형으로 벤딩한다.First, the wire rod is bent in a circle.

둘째, 일정한 굵기의 알루미늄으로 된 선재를 만들고자 하는 팩킹의 외형길이만큼 짜른다.Second, we squeeze the outer length of packing to make wire rod of aluminum of constant thickness.

셋째, 짤려진 선재의 양끝단을 용접한다.Third, weld both ends of the cut wire.

넷째, 용접부위의 슬래그(찌꺼기)를 제거한다.Fourth, remove slag from the welded area.

다섯째, 선재의 굵기와 용접부위의 굵기를 연삭작업을 통하여 균일하게 만든다.Fifth, make the thickness of wire rod and the thickness of welded part uniform through grinding work.

그런데, 위와 같은 종래 방법으로 만들어진 팩킹의 문제점은 다음과 같다.However, the problems of the packing made by the conventional method as described above are as follows.

첫째, 일정한 규격으로 선재를 절단하지만 용접작업으로 완성품의 규격이 일정하지 못하다.First, the wire is cut to a certain size, but the size of the finished product is not constant by welding.

둘째, 작업공정이 많고, 까다로워 생산성 및 작업능률이 저하된다.Second, there are many work processes, which are difficult to reduce productivity and work efficiency.

셋째, 부품으로 작업공정에 사용될 때 용접부위가 떨어져 작업의 능률저하 및 불량품의 양산을 초래할 우려가 있다.Third, when used in the work process as a component, there is a fear that the welded parts fall, resulting in a decrease in efficiency of work and mass production of defective products.

넷째, 용접부위와 선재의 굵기를 같게 하기 위하여 연삭작업을 하지만, 작업자체가 수작업이고, 작업물인 선재가 원형이므로 균일한 작업이 이루어지지 않아 팩킹의 굵기가 상이해진다.Fourth, but the grinding work in order to make the same thickness of the welding site and the wire, but the worker body is a manual work, since the wire is a circular work, the uniform work is not made, the thickness of the packing is different.

위에서 살펴본 바와 같이 종래의 방법은 제작상의 어려움 뿐만아니라 제품의 균일성도 문제점으로 제기되었던 바, 이에 본 발명인은 위에서 본 바와 같은 제작상의 어려움을 제거하고, 제품 또한 균일하며 대량생산이 쉽게 될 수 있는 방법을 발명하게 된 것이다.As described above, the conventional method has been raised as a problem of uniformity of the product as well as the difficulty of manufacturing, and thus the present inventors eliminate the difficulty of manufacturing as described above, and the product can also be uniform and mass produced easily. It is to be invented.

본 발명의 제작방법을 이하에 첨부된 도면과 함께 살펴보기로 한다.The manufacturing method of the present invention will be described with reference to the accompanying drawings.

우선 적당한 크기로 만들어진 원형의 알루미늄파이프(1)를 일반적인 선반의 척(2)으로 고정시키고, 선반 양측의 공구대(3,3a)에 외측가공바이트(4)를 공구대(3)에 그리고 내측가공바이트(4a)는 공구대(3a)에 삽입고정한 후, 척(2)에 고정되어 회전하는 알루미늄파이프(1)를 내측과 외측에서 동시에 원형으로 가공 및 절단을 한다.First, a circular aluminum pipe 1 made of a suitable size is fixed with a chuck 2 of a general lathe, and the outer machining bite 4 is attached to the tool rest 3 on the tool posts 3 and 3a on both sides of the lathe. After the machining bite 4a is inserted into the tool post 3a and fixed, the aluminum pipe 1 is fixed to the chuck 2 and rotates at the same time inside and outside in a circular shape.

즉, 단면이 원형이고, 전체형상 또한 원형인 팩킹을 제작할 때, 반원씩 가공하는 2개의 바이트를 사용하면, 각 바이트가 반원을 가공하여, 하나의 완성된, 단면이 원으로 된 팩킹이 되는 것이다.In other words, when manufacturing a packing having a circular cross section and a circular shape as a whole, if two bytes are processed by semicircles, each byte processes a semicircle, so that one completed cross section is a circular packing. .

이때, 각 바이트는 알루미늄파이프를 반원만큼 깍아 주면서 절단작업도 함께 이루어지는 것이다.At this time, each bite is made by cutting the aluminum pipe by a half circle.

본 발명이 비록 알루미늄파이프를 두 개의 바이트로 반원씩 깍아주는 간단한 방법이라고 하더라도 이런 방법을 통하여 팩킹을 가공하는 것은 종래에 없었던 것이고, 그로 인한 효과는 종래의 용접에 의한 방법보다 훨씬 진보한 가공방법이 되는 것이다.Although the present invention is a simple method of cutting the aluminum pipe in half by two bytes, it has never been possible to process the packing by this method, and the effect is that the processing method is much more advanced than the conventional welding method. Will be.

본 발명 방법에 따른 팩킹 제조방법의 효과는 아래와 같다.The effect of the packing manufacturing method according to the present invention is as follows.

첫째, 원형의 알루미늄파이프를 바이트로 가공하므로 제품 규격이 일정하다.First, the product specifications are constant because circular aluminum pipes are processed into bites.

둘째, 절삭작업과 절단작업이 동시에 이루어지므로 작업시간이 단축된다.Second, the cutting work and the cutting work is done at the same time, thereby reducing the work time.

셋째, 종래의 제작방법에 비하여 작업공정이 확연히 줄어든다.Third, the work process is significantly reduced compared to the conventional manufacturing method.

넷째, 기계적 작업이 이루어지므로 같은 규격의 제품을 대량생산할 수 있다.Fourth, since the mechanical work is made it is possible to mass-produce products of the same standard.

다섯째, 용접부위 없이 일체형으로 제작되므로 불량발생이 없어진다.Fifth, since it is manufactured integrally without welding parts, the occurrence of defects is eliminated.

위와 같은 본 발명의 효과로, 본 발명공정에 따른 팩킹 제조방법은 팩킹제작 단가를 줄일 수 있고, 일정규격의 제품을 생산할 수 있게 되어 팩킹의 원래 목적인 밀폐성 확보를 완벽히 달성할 수 있게 된 것이다.With the effect of the present invention as described above, the packing manufacturing method according to the process of the present invention can reduce the manufacturing cost of the packing, it is possible to produce a product of a certain standard it is possible to achieve a complete seal to ensure the original purpose of the packing.
