본 발명은 건설현장 등에서 너트형 연결금구를 이용하여 철근을 연결할 수 있도록 철근의 단부에 나사를 성형하는 이동식 자동 철근 전조기에 관한 것으로서, 보다 구체적으로는 철근 단부에 나사를 형성하는 작업이 간편하게 신속하게 이루어지도록 한 이동식 자동 철근 전조기를 제공코자 한 것이다.The present invention relates to a mobile automatic rebar rolling machine for forming a screw on the end of the reinforcing bar so as to connect the reinforcement using a nut-type connection bracket in the construction site, more specifically, the operation of quickly forming the screw on the end of the reinforcing bar It is to provide a mobile automatic rebar rolling machine to make it possible.

건설현장 등에서는 건축물의 기둥, 슬래브 등의 내구성을 위해서 콘크리트를 타설하기 전에 거푸집 내측에 철근 구조물을 설치한 상태에서 콘크리트를 타설하게 된다.At the construction site, the concrete is placed in the state where the reinforcing structure is installed inside the formwork before placing the concrete for durability of the pillars, slabs, etc. of the building.

상기 철근 구조물의 경우 다수개의 철근을 수직 및 수평 방향으로 연결하여 사용하게 되는데, 일반적인 연결방법으로는 이웃하는 2개의 철근을 서로 포개지도록 한 상태에서 가는 철사를 이용하여 상호 결속 고정하였다.In the case of the reinforcing structure is used to connect a plurality of reinforcing bars in the vertical and horizontal directions, as a general connection method is fixed to each other by using a thin wire in a state in which two neighboring reinforcing bars overlap each other.

이런 방법의 경우 단층 구조물 등에는 큰 염려가 없으나, 고층 건물에 이런 철근 연결방법을 적용할 경우 가는 철사의 부식이 발생할 때 이웃하는 2개의 철근이 분리되는 구성으로 특히 지진 등에 매우 취약한 문제점이 있었다.In the case of such a method, there is no great concern for the single-layer structure, but when the reinforcing bar connection method is applied to a high-rise building, two neighboring reinforcing bars are separated when the corrosion of the thin wire occurs.

근자에는 상기한 문제점을 해결코자 2개의 철근 끝단을 서로 맞댄 상태에서 외부에 연결금구를 체결하는 연결방법이 많이 사용되고 있다.In order to solve the above problems, a connection method of fastening the connection bracket to the outside in a state where two rebar ends are facing each other is widely used.

상기한 연결방법은 철근 외부에 씌워지는 상하 양분되는 연결부재에 나사를 형성하고, 이 나사에 너트를 체결하여 2개의 철근이 결속 고정되도록 한 것이나, 이는 연결금구에 의해 연결부위가 과도하게 굵어지는 문제점이 있고, 연결금구의 부품이 많아 생산비용이 많이 소요되는 등의 문제점이 있었다.In the above connection method, a screw is formed on the upper and lower bisecting connecting members which are covered on the outside of the reinforcing bar, and the nut is fastened to the two screws so that the two reinforcing bars are fixed and fixed. There is a problem, such as a large number of parts of the connection bracket takes a lot of production costs.

이런 문제점을 해결하기 위한 수단으로 철근에 나사를 형성하고, 이 나사에 너트형 연결금구를 결합하는 연결방법이 제안되고 있으나, 철근의 표면에 요철이 형성되어 있는 등의 이유로 나사 성형에 많은 어려움이 있었고, 또한 과도한 비용이 소요되므로 현재까지 실용화 되지 못하고 있는 실정이다.As a means to solve this problem, a connection method for forming a screw in the reinforcing bar and joining a nut-type connecting bracket to the screw has been proposed, but it is difficult to form a screw due to irregularities formed on the surface of the bar. In addition, since excessive costs are required, it is not practical to date.

이에 본 발명자는 철근의 양 단부에 형성되는 나사를 저렴한 비용으로 신속하게 형성할 수 있게 함으로 해서 내구성 향상 및 금구의 굵기를 최소화 한 너트형 연결금구를 사용할 수 있게 함에 발명의 기술적 과제를 두고 본 발명을 완성한 것이다.The present inventors have the technical problem of the present invention to enable the use of nut-type connecting brackets that can improve the durability and minimize the thickness of the bracket by being able to quickly form a screw formed on both ends of the reinforcement at low cost Will be completed.

상기 기술적 과제를 해결할 수단으로 본 발명에서는 철근을 클램핑한 상태에서 모터로 정역 구동되고 실린더에 의해 전후 이동하는 선삭툴 및 전조툴에 의해 철근의 단부를 선삭 및 전조하여 나사를 성형되게 한 이동식 자동 철근 전조기에 의해 이루어질 수 있게 한 것이다.In the present invention as a means to solve the above technical problem is a mobile automatic reinforcing bar that is driven forward and backward with a motor in the clamped state of the rebar, turning and rolling the end of the rebar by a turning tool and a rolling tool that is moved back and forth by the cylinder to form a screw It is made possible by a rolling machine.

본 발명에 의하면 선삭툴 및 전조툴에 의해서 철근 단부의 선삭 및 나사 전조가 연속적으로 이루어지므로 나사 가공을 신속하게 행할 수 있고, 나사 가공에 따른 비용을 획기적으로 절감할 수 있는 것이다.According to the present invention, since turning and screw rolling of the reinforcing bar ends are successively performed by the turning tool and the rolling tool, the screw machining can be performed quickly, and the cost associated with the screw machining can be drastically reduced.

상기 정지수단(150)은 도 11 내지 도 12에 도시된 바와 같이 선삭툴(50)의 외측커버(56)에 설치되는 것으로서, 그 구성은 외측커버(56)의 중심 측방에 나사 결합된 볼트(151)에 전방으로 손잡이(153)가 돌출 형성된 정지판(152)을 회동 자재되게 결합하고, 정지판(152)의 후단과 외측커버(56)의 가장자리 측에 결합된 스프링 고정핀(154) 사이에 스프링(155)을 설치하여, 평상시에는 정지판(153)이 상사점 위치로 회동되어 있다가 철근(200)을 투입할 때 손잡이(153)를 잡고 하사점 위치로 회동시키면 외측커버(56)의 중심에 형성된 구멍을 차단하여 철근(200)의 내입을 정지시키는 역할을 하게 되는 것이며, 정지판(152)의 상·하측에는 정지판(152)이 상/하사점에서 정지할 수 있도록 외측커버(56)에 2개의 스토퍼 핀(156)을 결합한 구성이다.The stop means 150 is installed in the outer cover 56 of the turning tool 50 as shown in Figures 11 to 12, the configuration is a bolt screwed to the center side of the outer cover 56 ( 151 is pivotally coupled to the stop plate 152 with the handle 153 protruding forward, between the rear end of the stop plate 152 and the spring fixing pin 154 coupled to the edge side of the outer cover 56. Spring 155 is installed on the stop plate 153 is normally rotated to the top dead center position, and when the reinforcement 200 is put in the handle 153 to rotate the bottom dead center position when the outer cover 56 Block the hole formed in the center of the reinforcement 200 is to serve to stop the inside, the upper and lower sides of the stop plate 152, the outer cover to stop at the top / bottom dead center stop plate 152 Two stopper pins 156 are coupled to 56.

이상과 같이 구성되는 본 발명의 이동식 자동 철근 전조기(1)를 이용하여 건설현장에서 철근(200)의 단부에 나사를 전조 성형코자 할 시에는 기체(3) 하부에 설치되어 있는 캐스터(2)를 이용하여 작업장으로 이동시킨 상태에서 통상의 방법으로 제어기(130)에 전원을 연결한다.Caster (2) is provided in the lower part of the base (3) when forming a screw to the end of the reinforcement 200 in the construction site by using the mobile automatic reinforcing rod (1) of the present invention configured as described above Connect the power to the controller 130 in a conventional manner in the state moved to the workplace using.

이런 상태에서 클램핑부(90)의 양측 클램프(92) 사이로 철근(200)을 공급한 후 제어기(130)에서 전원을 인가하면 클램핑부(90)의 가압용 실린더(94)가 구동되어 양측 클램프(92)로 철근(200)을 클램핑하게 된다. In this state, when the reinforcement 200 is supplied between the two clamps 92 of the clamping unit 90, and then the power is applied from the controller 130, the pressurizing cylinder 94 of the clamping unit 90 is driven to both clamps ( 92) to clamp the rebar 200.

이때 본 발명을 도 11 내지 도 12와 같이 구성할 경우 철근(200)의 공급정도를 정확하게 하여 작업 효율성을 높일 수 있다. 즉, 철근(200)을 공급할 때 작업자는 선삭툴(50)을 구성하는 외측커버(56)에 설치된 정지수단(150)의 손잡이(153)를 파지한 상태에서 정지판(152)을 하사점 위치로 회동시킨 상태이므로 철근(200) 단부가 정지수단(150)에 밀착되면 클램핑부(90)로 철근(200)을 클램핑하면 된다. In this case, when the present invention is configured as shown in FIGS. 11 to 12, the supply accuracy of the rebar 200 can be accurately increased to increase the work efficiency. That is, when supplying the reinforcing bar 200, the operator lowers the stop plate 152 at the bottom dead center position while holding the handle 153 of the stop means 150 installed on the outer cover 56 constituting the turning tool 50. Since the rebar 200 is in close contact with the stop means 150, the rebar 200 may be clamped by the clamping unit 90.

철근(200)의 클램핑이 완료된 상태에서 정지판(152)에 형성된 손잡이(153)에서 파지 상태를 해제하면 정지판(152)의 후단과 외측커버(56) 사이에 설치되어 있 는 스프링(155)의 장력에 의해 상향 회동되어 작동대기 상태를 유지하게 된다.The spring 155 is provided between the rear end of the stop plate 152 and the outer cover 56 when the grip state is released from the handle 153 formed on the stop plate 152 in the state where the clamping of the rebar 200 is completed. It is rotated upward by the tension of to maintain the operating standby state.

상기와 같이 정지수단(150)이 철거되면 툴이송용 실린더(30)가 구동되면서 툴 안치판(20) 및 모터설치판(10)을 밀어서 전진시키는데, 이때 모터(12)는 정회전 구동되면서 전조툴(40) 및 선삭툴(50)을 정회전 구동하게 된다.When the stop means 150 is dismantled as described above, the tool transfer cylinder 30 is driven while the tool mounting plate 20 and the motor mounting plate 10 are pushed forward. In this case, the motor 12 is driven by forward rotation. The tool 40 and the turning tool 50 are driven to rotate forward.

상기와 같이 툴 안치판(20) 등의 툴이송용 실린더(30)에 의해 이송되면 먼저 선삭툴(50)의 중심으로 철근(200)의 선단이 내입된다.When it is conveyed by the tool conveying cylinder 30, such as the tool mounting plate 20 as mentioned above, the front-end | tip of the reinforcement 200 is inserted in the center of the turning tool 50 first.

이때 선삭툴(50)은 4개의 툴(55)이 벌어진 상태이고, 슬라이드판(64)에 결합되어 있는 2개의 접지롤러(66)가 스톱핑수단(72)에 의해 정지된 상태인 레일용 슬라이드부재(70)에 설치된 링형 레일(71)의 전후측에 위치한 상태이므로 슬라이드판(64)은 선삭툴 본체(52)상의 가이드 구멍(63)을 따라서 내측커버(51) 쪽으로 이동하게 된다.At this time, the turning tool 50 is a slide for rails in which four tools 55 are opened and two ground rollers 66 coupled to the slide plate 64 are stopped by the stopping means 72. Since the state is located at the front and rear of the ring-shaped rail 71 provided in the member 70, the slide plate 64 is moved toward the inner cover 51 along the guide hole 63 on the turning tool body 52.

상기와 같이 슬라이드판(64)이 이동하면 슬라이드판(64)의 하측으로 형성되어 있는 이송돌기(64a)가 툴이송부재(59)의 접지부(59b)와 하사점 위치에서 상사점 위치인 이송돌기(64a) 상측으로 이동되면서 스프링(62)에 탄성 지지되도록 작동구멍(58)에 내입되어 있는 툴이송부재(59)가 툴(55)을 이동시키게 된다.When the slide plate 64 is moved as described above, the transfer projection 64a formed at the lower side of the slide plate 64 is transferred at the top dead center position from the bottom dead center position with the ground portion 59b of the tool transfer member 59. The tool transfer member 59 embedded in the operation hole 58 moves the tool 55 to be elastically supported by the spring 62 while being moved upward of the projection 64a.

즉, 4개의 툴(55) 중 하나에 형성되어 있는 요홈(57)에 끼워진 툴이송부재(59)가 움직이면 이등변 삼각형의 경사면(55b)에 이웃하는 툴(55)의 개선된 접지면(55c)이 맞닿은 구조이므로 4개의 툴(55)이 동시에 선삭 위치로 내향 이동하여 철근(200)의 표면에 형성된 요철면을 선삭 가공하게 된다.That is, the improved ground plane 55c of the tool 55 neighboring the inclined plane 55b of the isosceles triangle when the tool conveying member 59 fitted in the recess 57 formed in one of the four tools 55 moves. Because of the abutting structure, the four tools 55 simultaneously move inward to the turning position to turn the uneven surface formed on the surface of the rebar 200.

상기 선삭 가공은 슬라이드판(64)의 하측에 형성된 이송돌기(64a)의 상사점 직선구간에서 이루어지는 것으로서, 하우징용 슬라이드부재(21)가 스톱핑수단(72)에 의해 정지 상태에 있는 레일용 슬라이드부재(70)와 접하는 순간 툴이송부재(59)는 슬라이드판(64)의 이송돌기(64a) 상사점 말미에서 하사점 위치로 이동하게 되고, 툴이송부재(59)가 스프링(62)의 탄성력에 의해 복원되면서 4개의 툴(55)을 외향 이동시켜 선삭 대기상태가 된다.The turning is performed in the top dead center straight section of the transfer projection 64a formed on the lower side of the slide plate 64, and the slide for rails in which the housing slide member 21 is stopped by the stopper means 72 is stopped. At the moment of contact with the member 70, the tool transfer member 59 is moved to the bottom dead center position at the end of the top dead center of the feed projection 64a of the slide plate 64, and the tool transfer member 59 is the elastic force of the spring 62. While restoring, the four tools 55 are moved outward to be in a waiting state for turning.

상기와 같이 선삭 가공이 진행되는 동안 본 발명에 의하면 툴(55)을 보호하기 위한 수단으로 절삭유가 공급되는데, 절삭유의 공급은 고정링(54)에 형성되어 있는 공급공(54a)과 내측커버(51)에 형성된 환형홈(51b) 및 이에 연결된 유로(51c)를 통해서 지속적으로 공급이 이루어지게 된다.According to the present invention during the turning process as described above, the cutting oil is supplied as a means for protecting the tool 55, the supply of the cutting oil is supplied to the supply hole 54a and the inner cover formed in the fixing ring 54 Supply is continuously made through the annular groove 51b formed in the 51 and the flow path 51c connected thereto.

철근(200)의 선삭 가공이 마무리된 상태에서도 선삭된 부분에 나사가 전조되도록 툴이송용 실린더(30)는 계속 전진하게 된다.Even when the turning of the rebar 200 is finished, the tool transport cylinder 30 continues to be advanced so that the screw is rolled to the turned portion.

즉, 상기와 같이 선삭 가공이 완료된 상태에서 4개의 툴(55)이 외향 이동되고, 툴이송용 실린더(30)가 계속 전진하게 되면, 산삭된 철근(200)은 툴하우징(22)의 후방에 설치되어 있는 회전하는 전조툴(40)을 구성하는 3개의 나사성형롤러(42) 사이로 공급되면서 나사가 형성되며, 일정구간 나사가 성형된 상태일 때 모터설치판(10) 아래쪽에 설치되어 있는 노브(100)는 클램핑부(90)와 근접한 위치의 엔드 스위치(103)에 접점 된다. 이때 커버(23)에 형성되어 있는 공급공(23a) 및 전조툴 고정판(17)에 형성된 유로(17a)를 통해서 절삭유가 지속적으로 공급되어 전조툴(40)을 냉각하게 된다.That is, when the four tools 55 are moved outwards while the turning process is completed as described above, and the tool transfer cylinder 30 continues to move forward, the crushed rebar 200 is located at the rear of the tool housing 22. The screw is formed while being supplied between the three screw-forming rollers 42 constituting the rotating rolling tool 40 installed, and the knob is installed below the motor mounting plate 10 when the screw is formed for a certain period. 100 is in contact with the end switch 103 in the position close to the clamping portion (90). At this time, the cutting oil is continuously supplied through the supply hole 23a formed in the cover 23 and the flow path 17a formed in the rolling tool fixing plate 17 to cool the rolling tool 40.

상기와 같이 노브(100)가 엔드 스위치(103)에 접점되면 툴이송용 실린더(30) 및 모터(12)는 정방향 구동이 멈추고 역방향 구동이 이루어진다.As described above, when the knob 100 is in contact with the end switch 103, the tool transfer cylinder 30 and the motor 12 stop forward driving and reverse driving.

툴이송용 실린더(30) 및 모터(12)가 역방향으로 구동되면 나사가 단부에 형성된 철근(200)은 클램핑수단(80)에 의해 고정된 상태에서 모터(12) 및 전조툴(40)과, 선삭툴(50)이 설치되어 있는 툴하우징(22) 등은 시작위치 스타트스위치(101) 쪽으로 후퇴하게 된다.When the tool conveying cylinder 30 and the motor 12 are driven in the reverse direction, the rebar 200 having the screw threaded at the end is fixed to the motor 12 and the rolling tool 40 in a state of being fixed by the clamping means 80, The tool housing 22 and the like in which the turning tool 50 is installed are retracted toward the start position start switch 101.

상기와 같이 후퇴하게 되면 환형 레일(71)이 결합되어 있는 레일용 슬라이드부재(70)는 슬라이드판(64)을 작동시키지 않고 다른 부재들과 함께 1차 후퇴가 이루어지게 된다.When retracted as described above, the rail slide member 70 to which the annular rail 71 is coupled has a first retraction with other members without operating the slide plate 64.

이런 상태에서 모터설치판(10) 아래쪽에 설치되어 있는 노브(100)는 일시정지 스위치(102)를 접점시키게 되는데, 일시정지 스위치(102)가 접점되면 툴이송용 실린더(30) 및 모터(12)의 구동이 모두 정지되며, 아울러 클램핑부(90)의 양측 클램프 가압용 실린더(94)가 후퇴하면서 철근(200)을 언클램핑하게 되므로 이때 작업자는 나사가 전조된 철근(200)을 인출하고 가공할 철근(200)을 상기에서와 같은 방법으로 다시 내입하면 된다. In this state, the knob 100 installed below the motor mounting plate 10 is brought into contact with the pause switch 102. When the pause switch 102 is contacted, the tool transfer cylinder 30 and the motor 12 are contacted. ) Are all stopped, and both clamping cylinders 94 of the clamping unit 90 are retracted to re-clamp the rebar 200 while the worker pulls out the rebar 200 that has been screwed and processed. The reinforcing bar 200 may be reinserted in the same manner as described above.
