본 발명은 케이블 단부에 슬리브를 끼우되 이동 자재한 인발다이스로서 슬리브를 단면 수축시킴과 동시에 신장시켜 고정시키는 타이케이블의 단부 가공장치에 관한 것으로, 특히 유압을 이용한 피스톤 작동에 의해 슬리브를 압착연신시키도록 하는 것이다.The present invention relates to an end processing apparatus for a tie cable which is inserted into a sleeve at a cable end but extends and fixes the sleeve as a drawing die which is a moving material. Particularly, the sleeve is pressed and stretched by a piston operation using hydraulic pressure. To do that.

종래 타이케이블의 단부 가공장치에 있어서는 상,하 금형 사이에 삽착시킨 슬리브내에 케이블 일단을 끼운 다음 금형을 햄머등으로 타격하여 슬리브를 케이블에 압착시켜 왔었다. 그러나 이와 같은 단조 방법에 의한 가공은 작업이 어렵고, 작업시간이 길뿐 아니라, 일정한 단면수축 및 신장율이 일정치 않아 제품의 일률성이 없고 생산성이 낮아 대량생산을 할 수 없는 문제점이 지적되고 있다.In the conventional end cable processing apparatus of a tie cable, one end of a cable is inserted into a sleeve inserted between upper and lower molds, and then the mold is pressed with a hammer to press the sleeve to the cable. However, it is pointed out that the processing by the forging method is difficult, not only long working time, but also constant cross-sectional shrinkage and elongation rate is not uniform, there is no uniformity of the product and low productivity can not be mass-produced.

본 발명은 제작이 쉽고 생산성을 향상시킬 수 있도록 하기 위하여 기대 상방에 설치한 유압실린더 일측의 피스톤에 의해 이동 자재토록 하는 이동구을 설치하고, 이 이동구의 작동봉에 이동 작동구를 설치한 다음, 이 동작동구 일측에 인발다이스를 고착시켜서 된 것으로 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to install the movable tool to move by the piston of the hydraulic cylinder one side installed above the expectation in order to be easy to manufacture and improve the productivity, and then install the movable operating tool on the operating rod of the movable tool, When the drawing dies are fixed to one side of the operating tool, the detailed description will be given as follows.

즉, 기대(1)상방의 고정판(2)과 고정판(2')사이에 유압실린더(3)을 고착하고, 유압실린더(3)일측에 연설시킨 피스톤(4') 작동로드(4)를 안내레일(5)상방의 이동구(6)에 나착케한 다음, 기대(1)상방일측의 고정판(7)과 고정판(2)사이에 안내봉(8)을 설치하여 작동구(9)를 습득자재토록 하되, 작동구(9)일단과 상기 이동구(6)를 습동자재토록 하되, 작동구(9)일단과 상기 이동구(6)를 작동봉(10)으로 연결 고착하고, 작동구(9)일측에 인발다이스(11)를 고착시키며 고정판(2)일측에 중심 고정원판(12)을 고착시켜서 된 것이다. 상기에 있어서, 이동구(6)하방에는 안내레일(5)을 따라 이동구(6)가 이동자재토록 바퀴(6')를 부설토록 하고 있으며, 인발다이스(11) 일측의 테이퍼(11')면에 슬리브(13)가 용이하게 끼워지고 후술하는 바와 같이 용이하게 통과될 수 있도록 슬리브(13)일측을 테이퍼지게 하고, 중심고정원판(12)에 단턱(12')을 형성시켜 후술하는 바와 같이 슬리브(13)의 타측이 단턱(12')에 걸려지게 한다.That is, the hydraulic cylinder 3 is fixed between the fixed plate 2 and the fixed plate 2 'above the base 1, and the piston 4' operating rod 4 guided to the hydraulic cylinder 3 side is guided. After attaching to the movable hole 6 above the rail 5, a guide rod 8 is provided between the fixed plate 7 and the fixed plate 2 on the upper side of the base 1 to acquire the operating tool 9. While freely, one end of the operating tool (9) and the movable tool (6) to the sliding material, the one end of the operating tool (9) and the movable tool (6) is fixed to the operating rod 10, and the operating tool ( 9) The draw die 11 is fixed on one side, and the fixed plate 2 is fixed by fixing the center fixing plate 12 on one side. In the above, below the movable port 6, the movable tool 6 is provided with the wheel 6 'along the guide rail 5, and the taper 11' of one side of the drawing die 11 is provided. The sleeve 13 is easily fitted to the surface and tapered on one side of the sleeve 13 so that the sleeve 13 can be easily passed as described below, and a stepped 12 'is formed on the central fixing plate 12, as will be described later. The other side of the sleeve 13 is caught by the step 12 '.

Another draw die (11A) having a one-sided cross-section of the wedge to install the draw die in a double, so as to more firmly press the sleeve (13) to the cable (C).

또한, 후술하는 바와 같이, 슬리브(13)를 인발다이스(11)로서 압착한 후 슬리브(13)가 신장되어진 후에 고정구(9)를 제4도중 좌측으로 이동시킨 다음, 중심고정원판(12)의 단턱(12')에 이탈구(15)를 삽입시켜 슬리브가 끼워진 케이블을 인발다이스(11)로부터 이탈시키게 되어 있다.Further, as will be described later, after the sleeve 13 is pressed as the drawing die 11 and the sleeve 13 is extended, the fastener 9 is moved to the left side in FIG. 4, and then the center fixing plate 12 The release port 15 is inserted into the step 12 'so that the cable fitted with the sleeve is separated from the drawing die 11.

도면중 3',3＂는 유압 유출입구, 7'는 고정판(7)의 뚫어진 구멍, 9'는 작동구(9)의 구멍, 12＂ 및 14'는 고정볼트, 16는 고정 및 연결볼트, 17은 방수마개이다.3 ', 3' is the hydraulic outlet, 7 'is the drilled hole of the fixing plate (7), 9' is the hole of the operating hole (9), 12 'and 14' is the fixing bolt, 16 is fixed and connecting bolt, 17 is a waterproof plug.

이와 같이 구성된 본고안의 작용효과는 다음과 같다. 유압 유출입구(3')측으로 유압을 공급시키면 실린더(3)내의 피스톤(4')이 제4도시의 좌측으로 이동하게 되어 작동로드(4)도 따라 이동하고, 작동로드(4)의 이동에 따라 이동구(6)가 이동하여 이동구(6)에 연결고착된 작동봉(10)이 작동구(9)를 좌측을 밀게 된다. 이때, 작동구(9)의 이동거리를 슬리브(13)가 인발다이스(11) 테이퍼(11')면과 중심고정원판(12)사이에 끼워질 수 있도록 유압공급 조작을 조정하여 정하게 된다.The operational effects of the proposed paper thus constructed are as follows. When the hydraulic pressure is supplied to the hydraulic outlet 3 'side, the piston 4' in the cylinder 3 moves to the left side of the fourth illustration, so that the operating rod 4 also moves along the movement of the operating rod 4. Accordingly, the movable tool 6 moves and the operating rod 10 fixed to the movable tool 6 pushes the operating tool 9 to the left. At this time, the movement distance of the operating port 9 is determined by adjusting the hydraulic pressure supply operation so that the sleeve 13 can be fitted between the drawing die 11 taper 11 'surface and the center fixing plate 12.

이와 같이 작동구(9)가 도면중 좌측으로 이동한 상태에서 케이블(C)를 고정판(7)의 구멍(7')-작동구(9)의 구멍(9')-인발다이스(11)의 구멍(11＂)를 통과 시키면서 케이블(C)의 단부에 슬리브(13)를 끼우되, 슬리브(13)일측의 테이퍼부를 인발다이스(11)의 테이퍼(11')면에 위치시키고, 타측은 중심고정원판(12)의 단턱(12')에 걸리도록 한 다음, (제5도 참조) 실린더(3)의 유압 유출입구(3＂)를 통해 유압을 공급시켜 피스톤(4')을 제4도시에서 우측으로 이동시킨다. 그러면 피스톤 작동로드(4)는 이동구(6)를 우측으로 밀어 이동구(6)가 레일(5)를 따라 이동하게 되고, 이에 따라 이동구(6)에 연결고착된 작동봉(10)타측의 작동구(9)가 이동하게 되므로, 작동구(9)일측에 고착된 인발다이스(11)가 중심고정원판(12)측으로 이동하면서 슬리브(13)를 단면수축시켜 슬리브(13)의 내주면이 케이블(C)단부에 압착하게 됨과 동시에, 슬리브(13)일단이 신장되어 지게 된다. 즉, 슬리브(13)가 인발다이스(11)의 이동에 의해 단면 수축되면서 이의 내경이 케이블(C)외주면에 압착고정되고, 슬리브(13)일단이 신장되어 케이블(C)일단과 슬리브(13)일단의 내경사이에 공간부가 형성되어진다(제6도 및 제10도 참조).In this manner, the cable C is moved to the hole 7 'of the fixing plate 7-the hole 9' of the operating hole 9-the drawing die 11 in the state in which the operating tool 9 is moved to the left side in the drawing. Insert the sleeve 13 at the end of the cable C while passing through the hole 11 ', and position the taper portion on one side of the sleeve 13 on the taper 11' surface of the drawing die 11, the other side being the center. The piston 4 'is shown in a fourth position by being caught by the step 12' of the fixed disk 12, and then supplied with hydraulic pressure through the hydraulic outlet 3 'of the cylinder 3 (see FIG. 5). To the right. Then, the piston actuating rod 4 pushes the movable tool 6 to the right, and the movable tool 6 moves along the rail 5, and thus, the operating rod 10 connected to the movable tool 6 is fixed to the other side. Since the operating port 9 of the movement is moved, the drawing die 11 fixed to one side of the operating port 9 is moved to the center fixing plate 12 side shrinkage of the sleeve 13 to the end surface inner sleeve 13 of the sleeve 13 The cable C is pressed at the end, and at the same time, one end of the sleeve 13 is extended. That is, while the sleeve 13 is contracted in cross-section by the movement of the drawing die 11, its inner diameter is compressed and fixed to the outer peripheral surface of the cable C, and one end of the sleeve 13 is elongated to extend the cable C one end and the sleeve 13. A space portion is formed between one end of the inner diameter (see FIGS. 6 and 10).

이와 같이 슬리브(13)가 케이블(C)외주면에 압착되어 이의 단부에 공간부가 형성되어진 상태에서, 유압 유출입구(3')측으로 유압을 공급시켜 작동구(9)를 제4도중 좌측으로 약간 이동시키면, 작동구(9) 및 인발다이스(11)에 끼워진 슬리브(13)가 압착 고정된 케이블(C)도 이동하게 되고, 이때, 중심공정원판(12)의 단턱(12')에 이탈구(15)를 삽입시킨 다음, 유압 유출입구(3＂)측으로 유압을 공급시켜 작동구(9)를 제4도중 우측으로 이동시킨다. 그러면, 작동구(9)와 인발다이스(11)가 이탈구(15)측으로 이동되면서 이탈구(15)에 의해 케이블(C) 및 슬리브(13)가 밀려 케이블 단부가 인발다이스(11)로부터 이탈되어지게 된다.(제7도 참조) 따라서 케이블(C)단부에 슬리브(13)를 압착 고정시키는 과정이 완성되어지게 되는 것이다. 이후 제10도시와 같이 케이블(C)단부의 공간부에 마개(17)를 별도의 공구로써 끼워 넣어 슬리브(13)과 케이블(C)사이의 수밑을 유지토록 하고, 슬리브(13)외주면에 나사선을 형성시켜(도시 생략) 휘팅앵커부 즉, 타이케이블 단부의 가공을 완성시키게 된다. 한편, 제8도시와 같이 인발다이스(11)일측을 ＂

In this case, the cable C, to which the sleeve 13 fitted to the operating hole 9 and the drawing die 11 is pressed and fixed, is also moved. After inserting 15), hydraulic pressure is supplied to the hydraulic outlet port (3 ＂) to move the operating port 9 to the right in FIG. Then, the actuating tool 9 and the drawing die 11 are moved toward the release opening 15, and the cable C and the sleeve 13 are pushed by the release opening 15 so that the cable end is separated from the drawing die 11. (See FIG. 7) Therefore, the process of crimping and fixing the sleeve 13 to the end of the cable C is completed. Thereafter, as shown in FIG. 10, the stopper 17 is inserted into the space part of the end of the cable C as a separate tool to maintain the base between the sleeve 13 and the cable C, and a screw line is provided on the outer peripheral surface of the sleeve 13. (Not shown) to complete the machining of the fitting anchor portion, that is, the end of the tie cable. Meanwhile, as shown in the eighth city, one side of the drawing dies 11 is removed.

By combining another drawing die 11A having a one-sided cross-section to extend the length of the drawing die, it is possible to bring more cross-sectional shrinkage to the sleeve 13 passing through the drawing die 11 and 11A. The clamping of the sleeve 13 to the cable C can be made more secure.

이상과 같이 본 발명은 유압을 이용하여 인발다이스를 이동 자재토록하면서 케이블단부에 슬리브를 압착 고정시키도록 하므로서, 슬리브의 단면 수축 및 신장율을 인정케하여 제품의 일률성을 가져올 수 있고 작업시간의 단축, 대량생산의 향상을 가져오는 특성이 있다.As described above, the present invention allows the sleeve to be press-fitted to the cable end while the drawing die is moved by using hydraulic pressure, thereby acknowledging the shrinkage and elongation rate of the sleeve to bring uniformity of the product and to reduce the working time. There is a characteristic that improves mass production.
