Abstract

A fitting anchor member (1) of a tie cable (3) has a sleeve (4) compressively fitted onto a cable (3) at its end. The fitting anchor member is chucked to a carriage (8) on a lathe bed (7), and a cutter (11) is secured to a chuck (10) prepared on the main shaft of the lathe. The fitting anchor member on the carriage is fed at a regular speed towards the rotating die so as to form screw threads on the outer surface of the sleeve.

제3도는 타이케이블의 휘팅앵커부에 나사가공한 것을 보인 정면도.3 is a front view showing the threading of the fitting anchor portion of the tie cable.

제4도 및 제5도는 휘팅앵커부의 외주에 나사가공하는 방법을 설명하는 개략 단면도이다.4 and 5 are schematic cross-sectional views illustrating a method of screwing the outer periphery of the fitting anchor portion.

본 발명은 원통형 슬리브(Sleeve)내경에 케이블(Stranded Wire Cable) 단부를 삽입시킨후 슬리브를 압착하여 그 단면적 및 내경을 수축시켜, 삽입된 케이블과 슬리브를 일체로 되게 하여 타이케이블을 고정 가능하게 하는 타이케이블 휘팅앵커(Fitting anchor)부에 나사를 가공하는 방법에 관한 것이다.The present invention is to insert the end of the cable (Stranded Wire Cable) in the inner diameter of the cylindrical sleeve (sleeve) and then compress the sleeve to shrink the cross-sectional area and the inner diameter, so that the inserted cable and the sleeve to be integrated to secure the tie cable The present invention relates to a method of machining a screw in a tie cable fitting anchor.

타이케이블이란 스트랜드 와이어 케이블(Stranede Wire Cable) 단부에 원통형 슬리브(Sleeve)를 압착하여 휘팅앵커부(Fitting anchor)를 형성한 다음 그 외주에 나사산을 가공하여 너트로 체결되어 질 수 있게 한 것으로 토목이나 건축공사의 긴장용이나 버팀용줄로 사용되어지고 있다. 타이케이블에 있어 케이블과 슬리브와의 압착력이 뛰어나야만 큰 장력에 견딜 수 있으며, 휘팅앵커부 외주에 형성되는 나사산이 정밀하고 일정해야만 타이케이블이 체결될 시 굳은 결착력을 얻을수 가 있다.Tie cable is formed by fitting a cylindrical sleeve to the end of a stranded wire cable to form a fitting anchor, and then threading the outer periphery so that it can be tightened with a nut. It is used for tension and brace for building construction. Tie cable must be able to withstand the large tension only when the cable and the sleeve have excellent compressive force, and only when the thread formed on the outer part of the fitting anchor is accurate and consistent, firm binding force can be obtained when the tie cable is fastened.

일반적으로 환봉 외주면에 나사산을 형성하는 방법으로는 수공구로 환봉 외주를 회전시켜 나사산을 형성시키거나, 선반 등의 공작기구 주축에 가공물을 고정시키고, 가공물을 회전시키면서 좌우로 이동되게 고정되어 있는 절삭공구 즉, 바이트등으로 환봉외주를 절삭하여 나사산을 가공하는 방법이 있으나, 타이케이블과 같이 부피가 크고 중량물인 경우 선반에 고정한후 회전시킬 수 없어 수공구를 사용하여 휘팅앵커부에 나사산을 가공하여 왔다. 그로 말미암아 타이케이블을 대량생산할 수 없었음은 물론 그 제작단가도 상당히 소요되었다.In general, a thread is formed on the outer circumferential surface of the round bar to form a thread by rotating the outer circumference of the round bar with a hand tool, or to fix the workpiece to a machine tool spindle such as a lathe, and to rotate the workpiece. That is, there is a method of processing the thread by cutting the round bar outer circumference with a bite, etc., but if the bulky and heavy items such as tie cables can not be rotated after fixing to the shelf has been used to process the thread in the fitting anchor using hand tools. This prevented them from mass-producing tie cables, as well as the cost of manufacturing them.

본 발명은 타이케이블 휘팅앵커부에 나사산을 가공함에 있어 휘팅앵커부 일단을 왕복대에 고정시키고 선반의 주축에 고정된 절삭공구를 회전시켜 휘팅앵커부 외주에 나사산을 가공하는 방법으로 단시간내에 대량생산이 가능하게 할뿐만 아니라 균일 제품의 생산으로 불량률을 제지한 타이케이블 휘팅앵커부의 나사 가공 방법에 관한 것으로 이를 첨부한 도면에 의거 상세히 설명하면 다음과 같다.The present invention is a mass production in a short time by the method of processing the thread on the outer periphery of the fitting anchor by fixing one end of the fitting anchor to the carriage and rotating the cutting tool fixed to the main shaft of the lathe in machining the thread in the tie cable fitting anchor portion This is not only possible, but also relates to a thread processing method of the tie cable fitting anchor part which restrained the defective rate by the production of a uniform product.

본 발명인 타이케이블 휘팅앵커부(1)에 나사산(2)를 가공하는 방법을 설명하기에 앞서 케이블(3) 단부에 슬리브(4)를 압착시켜 휘팅앵커부(1)를 가공하는 방법을 설명하면 다음과 같다.Before describing a method of processing the thread 2 to the tie cable fitting anchor portion 1 of the present invention, a method of processing the fitting anchor portion 1 by compressing the sleeve 4 at the end of the cable 3 will be described. As follows.

제1도에 도시한 것과 같이 입구가 출구보다 큰 내경을 갖는 다이스(5) 입구에 일단이 테이퍼진면(6)을 갖는 원통형 슬리브(4)내경에 케이블(3)을 삽입시킨후 슬리브(4)를 화살표 방향 즉, 다이스(5) 내경으로 압축시켜 슬리브(4)의 내경 및 단면적이 수축되어 그 내경에 삽치된 케이블(3)을 압착하여 타이케이블의 휘팅앵커부(1)를 형성시킨다.As shown in FIG. 1, a cable 3 is inserted into an inner diameter of a cylindrical sleeve 4 having a tapered surface 6 at one end of a die 5 having an inner diameter larger than an outlet as shown in FIG. Is compressed in the direction of the arrow, that is, the inner diameter and cross-sectional area of the sleeve 4, and the cable 3 inserted into the inner diameter is compressed to form the fitting anchor portion 1 of the tie cable.

그후 제4도에 도시된 것과 같이 케이블(3) 단부에 슬리브(4)가 압착된 휘팅앵커부(1) 일단을 선반(7)의 왕복대(8)에 척(9)으로 고정시키며, 선반(7)의 주축에서 회전운동을 하는 회전구(10)에 절삭공구(11)를 설치한후, 왕복대(8)를 일정속도로 주축 방향으로 이송시킬때 주축에 고정되어 회전운동을 하는 절삭공구(11)로 휘팅앵커부(1) 외주에 나사산(2)이 가공되도록 하는 것이다.Then, as shown in FIG. 4, one end of the fitting anchor portion 1, in which the sleeve 4 is crimped to the end of the cable 3, is fixed to the carriage 8 of the shelf 7 with the chuck 9, and the shelf After the cutting tool 11 is installed in the rotary tool 10 which rotates on the main shaft of (7), the cutting is fixed to the main shaft and rotates when the carriage 8 is transferred in the direction of the main shaft at a constant speed. The tool 11 allows the thread 2 to be processed on the outer periphery of the fitting anchor 1.

즉, 휘팅앵커부(1)의 일단을 선반(7)의 왕복대(8)에 척(9)이나 유압을 이용한 척(도시없음)등으로 미동이 없게 견고히 고정시키고, 선반(7)의 주축에 회전운동을 하는 회전구(10) 내측에 나사산(2)을 절삭하는 절삭공구(11)를 삽치시켜 선반(7)이 주축이 회전할때 같이 회전운동을 하게 되며, 휘팅앵커부(1)를 고정하고 있는 왕복대(8)를 절삭공구(11)가 삽치되어 회전하고 있는 주축방향으로 이송시키면서 휘팅앵커부(1)외주에 나사산(2)이 가공되도록 하는 것이다.That is, one end of the fitting anchor portion 1 is firmly fixed to the shuttle 8 of the shelf 7 without a fine movement by using a chuck 9 or a chuck (not shown) using hydraulic pressure, and the main shaft of the shelf 7. Inserting the cutting tool 11 for cutting the thread (2) inside the rotary hole 10 to rotate the rotary movement to the shelf (7) to rotate as the main shaft rotates, the fitting anchor portion (1) The screw 2 is machined on the outer periphery of the fitting anchor 1 while the cutting tool 11 is inserted into and transported in the direction of the main axis in which the cutting tool 11 is fixed.

이와같이 절삭공구를 회전시켜 휘팅앵커부 외주에 나사산을 가공하는 방법은 수가공에 의해 가공되는 나사산보다 품질이 우수한 나사산을 얻을 수 있으며, 단 한번의 작업으로 단시간내에 휘팅앵커부에 나사산을 형성시킬 수 있어 대량생산을 가능하게 하여 경제적으로 타이케이브를 제작할 수 있게 한 것이다.As such, the method of machining a thread on the outer periphery of the fitting anchor by rotating the cutting tool can obtain a higher quality thread than the thread processed by the hand, and the thread can be formed on the fitting anchor in a short time in a single operation. It enables mass production so that it can be economically produced.
