Description

트랙슈 부싱의 제조방법{Cold precision forging of bushing insert}Manufacturing method of track shoe bushing {Cold precision forging of bushing insert}

본 발명은 궤도차량의 트랙슈에 사용되는 트랙슈 부싱의 제조방법에 관한 것 으로, 특히 소재를 단조가공하여 부싱을 제조하는 트랙슈 부싱의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a track shoe bushing for use in a track shoe of a tracked vehicle, and more particularly, to a method for manufacturing a track shoe bushing by forging a material to produce a bushing.

도1에는 궤도차량의 트랙슈와 트랙조립체에 인서트되는 부싱이 도시되는데, 트랙슈(1)는 상하모서리에 트랙조립체(2)를 가지며 트랙조립체(2)에는 부싱(3)이인서트된다. 트랙슈를 조립하여 궤도를 형성할 때는 도시되지 않은 핀이 부싱(3)에 삽입되어 너트로 고정된다.Fig. 1 shows a track shoe of a tracked vehicle and a bushing inserted into a track assembly. The track shoe 1 has a track assembly 2 at its upper and lower edges, and a bushing 3 is inserted into the track assembly 2. When assembling the track shoe to form a track, a pin (not shown) is inserted into the bushing 3 and fixed with a nut.

상기와 같은 부싱(3)은 내부에 8각형 관통홈(4)을 가지는 원통체로 종래에는 인발가공에 의하여 제조되고 적당한 길이로 절단하여 사용하였다. 그러나 이러한 부싱(3)은 수입되어 가격이 비싸고 강도가 우수하지 못하다.Bushing (3) as described above is a cylindrical body having an octagonal through groove (4) therein conventionally manufactured by drawing and used to cut to a suitable length. However, these bushings 3 are imported and are expensive and not strong.

본 발명의 목적은 종래의 트랙슈 부싱을 국산화하고 보다 우수한 강도를 가지도록 단조가공에 의해 제조하는 트랙슈 부싱의 제조방법을 제공하고자 하는 것이다.It is an object of the present invention to provide a method for manufacturing a track shoe bushing, which is manufactured by forging to localize a conventional track shoe bushing and have more excellent strength.

본 발명의 트랙슈 부싱의 제조방법은 소재를 상온에서 냉간단조에 의해 내부 에 8각형 블라인드 홈을 가지는 부싱 반제품을 가공하고 부싱의 반제품을 일정길이를 가지게 절단하여 8각형 관통홈을 가지는 원통형 부싱으로 완제품을 만들어 이루어진다.The manufacturing method of the track shoe bushing of the present invention is a cylindrical bushing having an octagonal through groove by processing a bushing semi-finished product having an octagonal blind groove inside by cold forging the material at room temperature and cutting the semi-finished product of the bushing to a certain length. The finished product is made.

도 1은 궤도차량의 트랙규와 트랙조립체에 인서트되는 부싱을 도시하는 도면.BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a view of a track guide and a bushing inserted into a track assembly of a tracked vehicle.

도 2는 본 발명의 제조방법에 의해 단조가공된 부싱 반제품을 도시하는 단면도.2 is a cross-sectional view showing a bushing semifinished product forged by the manufacturing method of the present invention.

도 3은 본 발명의 제조방법에 의해 제조된 최종 부싱을 도시하는 도면.3 shows a final bushing manufactured by the manufacturing method of the present invention.

본 발명을 첨부된 도면을 참조하여 상세히 설명한다.The present invention will be described in detail with reference to the accompanying drawings.

도2에는 본 발명의 제조방법에 의해 단조가공된 부싱 반제품이 도시되는데,소재를 상온에서 냉간단조에 의해 내부에 8각형 블라인드 홈(11)을 가지는 부싱 반 제품(10)을 가공한다.Fig. 2 shows a bushing semifinished product forged by the manufacturing method of the present invention. The bushing semifinished product 10 having an octagonal blind groove 11 therein is processed by cold forging the material at room temperature.

단조가공은 스틸(SCM2,SCr2,SCM4)을 2차 단조하여 이루어 질 수 있다.Forging can be done by secondary forging steel (SCM2, SCr2, SCM4).

도2에 도시된 부싱의 반제품을 일정길이를 가지게 절단하여 도3에 도시된 바와 같은 8각형 관통홈(12)을 가지는 원통형 부싱(13)으로 완제품을 만든다.The semifinished product of the bushing shown in FIG. 2 is cut to a certain length to make a finished product with a cylindrical bushing 13 having an octagonal through groove 12 as shown in FIG.

본 발명의 단조가공은 압축에 의한 금속의 유동이 다이내에서만 행하여지 며, 단조품은 조직이 미세하고 강도가 크다. 또한 1 회의 가압이나 타격으로 제품을 완성하기 어려우면 다단계로 가공하여 단조품을 제조할 수 있다.In the forging process of the present invention, the flow of metal by compression is performed only in the die, and the forging has fine structure and high strength. In addition, if it is difficult to complete the product in a single press or hitting can be forged by manufacturing in multiple stages.

상기와 같은 본 발명의 트랙슈 부싱의 제조방법에 의하면, 부싱이 단조가공에 의하여 제조되므로 강도가 우수하고 분당 60개 이상의 대량생산이 가능하여 원가절감의 효과를 제공한다.According to the manufacturing method of the track shoe bushing of the present invention as described above, since the bushing is manufactured by forging, the strength is excellent and mass production of 60 or more per minute is possible, thereby providing cost reduction effect.
