상기 나사전조다이(5)는 상기 보조다이(3)와의 사이에 소정 폭의 소재회전통로(6)가 형성될 수 있도록 이격 설치되며 회전축(M')과 연결 설치되는 나사전조다 이(5)는 각기 기계요소인 키와 볼트로 고정되며, 일반적인 기술이므로 도면과 설명은 생략한다.The screw rolling die 5 is a screw rolling die 5 which is installed to be spaced apart from the auxiliary die 3 so as to form a material rotation passage 6 having a predetermined width and connected to the rotating shaft M '. Are fixed with keys and bolts, which are mechanical elements, respectively, and thus, the drawings and descriptions thereof will be omitted.

한편 나사전조다이(5)의 일측으로는 안내장공(8')과 고정 볼트(8")를 통해 경사각도가 조절되는 지지테이블(8)상에서 역시 안내장공(8')과 고정 볼트(8")를 통해 이격 폭의 조절이 가능하도록 유동 가능하게 설치되는 한 조의 전, 후 수용판(7A)(7B)과 상기 전, 후 수용판(7A)(7B)을 상호 연결 지지할 수 있도록 전측 수용판(7A)을 관통하는 상태로 양단이 후측 수용판(7B)과 지지테이블(8)에 고정된 브라켓(9)에 연결 지지되도록 하는 지지봉(7C)을 포함하는 소재수용부(7)가 구성되며,Meanwhile, on one side of the thread rolling die 5, the guide hole 8 ′ and the fixing bolt 8 ″ are also supported on the support table 8 where the inclination angle is adjusted through the guide hole 8 ′ and the fixing bolt 8 ″. The front and rear receiving plate 7A (7B) and the front and rear receiving plate (7A) (7B) and the front and rear receiving plate (7A) (7B) that is installed so as to be able to adjust the separation width through the The material accommodating part 7 which comprises the support rod 7C which supports both the back side receiving plate 7B and the bracket 9 fixed to the support table 8 in the state which penetrates the plate 7A is comprised. ,

상기 소재수용부(7)의 일측단에는 상기 수용된 환봉(S1)을 일렬로 나사전조다이(5)로 공급하기 위한 가이드부(10)가 일체로 연결 설치된다.One side end of the material receiving portion 7 is integrally connected to the guide portion 10 for supplying the accommodated round bar (S1) to the thread rolling die (5) in a row.

상기 소재수용부(7)의 맞은 편에는 나사전조다이(5)에서 빠져나온 가공 완료되어 일측단에 나사산(S')이 형성된 환봉(S1)을 임시로 적치 수용하기 하기 위한 완제품 적치대(11)가 본체(1)의 전면에 고정 설치된다.On the opposite side of the material receiving portion (7) the finished product loading stand (11) for temporarily accommodating the round rod (S1) formed by the threaded thread (S ') at one end is completed by the process of exiting the thread rolling die (5) ) Is fixedly installed on the front surface of the main body 1.

한편, 상기 가이드부(10) 선단의 하방에는 회전되는 캠(13)에 의해 간헐적으로 왕복 출몰되는 푸셔(12')를 구비하는 소재투입기(12)를 설치하여 가이드부(10)에 일렬로 배열된 환봉(S1)을 하나씩 간헐적으로 소재회전통로(6)로 투입시키도록 한다.On the other hand, below the tip of the guide portion 10 is provided with a material feeder 12 having a pusher 12 'intermittently reciprocated by the rotating cam 13 is arranged in a row in the guide portion 10 Round bar (S1) to be intermittently put into the material rotation passage (6) one by one.

이와 같이 구성되는 본 발명의 나사산전조장치는 먼저 환봉(S1)의 길이에 맞춰 소재 수용부(7)의 전, 후 수용판(7A)(7B)을 고정 볼트(8")의 조작을 통해 안내장공(8')상에서 적정히 이동시켜 이격 폭을 조절하게 되며 소재 수용부(7)내에 수용된 환봉(S1)이 자동적으로 푸셔(12')상에 이동 재치될 수 있도록 안내장공(8')과 고정 볼트(8")를 통해 지지테이블(8)의 경사각을 적절히 조정시킨다.The thread rolling device of the present invention configured as described above first guides the front and rear receiving plates 7A and 7B of the material receiving part 7 to the length of the round bar S1 through the operation of the fixing bolt 8 ". The guide rod 8 'and the guide rod 8' are automatically moved to the pusher 12 'so that the round bar S1 accommodated in the material accommodating portion 7 can be automatically placed on the pusher 12'. The inclination angle of the support table 8 is appropriately adjusted through the fixing bolt 8 ".

상기 소재 수용부(7)내에 수용된 환봉은 도 2에서와 같이 가이드부(10)에 일렬로 배열되는 상태로 푸셔(12')까지 이어지고 있는 상태이다.The round bar accommodated in the material accommodating part 7 is in a state leading to the pusher 12 'in a state arranged in line with the guide part 10 as shown in FIG.

상기 구동 모터(M)의 구동에 의해 회전축(M')이 회전됨으로써 상기 회전축(M')에 연결된 나사전조다이(5)가 회전하게 되며, 동시에 콘트롤부(C)의 명령에 의해 소재 투입기(12)가 구동되어 푸셔(12')를 일정한 간격으로 간헐적으로 상승시킴으로써 푸셔(12')상에 얹혀져 있는 환봉을 1개씩 소재회전통로(6)로 삽입되도록 한다.As the rotating shaft M 'is rotated by the driving motor M, the screw rolling die 5 connected to the rotating shaft M' is rotated, and at the same time, the material feeder 12) is driven to raise the pusher 12 'intermittently at regular intervals so that one round bar on the pusher 12' is inserted into the material rotation passage 6 one by one.

상기 소재회전통로(6)로 일단이 삽입된 환봉은 나사전조다이(5)가 회전되므로 마찰력과 회전력에 의해 빨려들어 가면서 맞물려 돌아 양 다이(3)(5)의 압압력에 의해 환봉(S1)의 일단부에 나사산(S')이 형성되게 되는 것이다.One end of the round rod inserted into the material rotation passage 6 is rotated while being sucked by the friction force and the rotational force so that the thread rolling die 5 is rotated and the round bar S1 is pressed by the pressing force of both dies 3 and 5. One end of the thread (S ') is to be formed.

그리고 상기한 환봉의 투입은 간헐적으로 연속되는 푸셔(12')의 동작에 의해 나사전조과정이 연속으로 이루어지게 된다.And the input of the round bar is made by the screw rolling process by the operation of the intermittent continuous pusher 12 '.

상기 나사전조다이(5)를 통과하여 나사산(S')의 가공이 완료된 환봉은 자연낙하되어 완제품 적치대(11)로 수납되는 것이며 가공 완료된 환봉(S1)이 도 4에 나타나 있다.The round bar, through which the thread S 'is processed, passes through the thread rolling die 5, is naturally dropped to be stored in the finished product loading table 11, and the round bar S1 is shown in FIG.

한편 환봉의 양단에 나사산을 형성하고자 하는 경우에는 나사산을 가공하지 않은 쪽이 나사전조다이(5)로 향하도록 위치를 바꿔 수납시킨 상태에서 전술한 과정과 동일하게 나사전조과정을 거치면 된다.On the other hand, if you want to form a screw thread on both ends of the round bar, the thread rolling process is carried out in the same manner as described above in the state in which the non-threaded side is changed to accommodate the screw rolling die (5).

이상의 설명에 따르면, 본 발명은 구조가 매우 간단하여 고장 발생률이 적으며 제조공정의 단축 및 제조원가의 절감을 기할 수 있고 장치의 크기를 소형화하여 점유면적의 축소와 설치장소의 선정에 편의성을 기할 수 있는 효과가 있는 유용한 발명이다.According to the above description, the present invention is very simple in structure, so that the occurrence rate of the failure is small, the manufacturing process can be shortened and the manufacturing cost can be reduced, and the size of the device can be reduced in size to reduce the occupied area and select the installation place. It is a useful invention that has an effect.
