이상과 같은 기본공식의 세팅(Setting)된 상태에서, 모선재를 선재규격에 맞게 신선하려고 할시에는, 중앙처리장치(10)에 세팅된 공식에 적합하도록 사상부(2) 다이(4)의 경과 신선부(1) 다이(3)의 경 및 다이(DIES)의 스킵수(4-1,4-2,4-3) 그리고 슬립율(SLIP), 선속 즉 D.C모우터(5,5')의 속도등 데이타(DATA)를 키보오드(11)로 입력하면 입력된 데이타 (DATA)값은 중앙처리장치(10)에서 세팅된 기본공식에 의하여 연산된다.In the state where the basic formula is set as described above, when the mother wire is to be drawn to the wire rod standard, the progress of the die 4 of the finishing unit 2 to conform to the formula set in the central processing unit 10 is satisfied. Wire section 1 Die diameter 3 and number of skips DIES 4-1, 4-2, 4-3 and slip ratio SLIP, flux or DC motor 5,5 ' When data DATA, such as speed, is input to the keyboard 11, the input data DATA is calculated by the basic formula set in the CPU 10.

연산되어 얻은 계산값을 주파수로 변화시켜 이것이 신선기(1) 다이(DIES)와 사상기(2) 다이(DIES)를 구동시키는 D.C모우터 (5,5')의 회전속도를 지령하게 되므로서 D.C모우터(5,5')가 구동하게 된다.By converting the calculated value to frequency, it commands the rotational speed of the DC motor (5,5 ') driving the die (1) die and the casualty (2) die (DC). The motors 5 and 5 'are driven.

이때 구동하는 신선기(1)와 사상기(2)의 D.C모우터(5,5')의 회전속도(RPM)을 펄스제네레이터(6,6')에서 검출하여, 검출된 회전속도(RPM) 값과 중앙처리장치(10)에서 계산된 값을 비교기 (8,8')에 비교한다.At this time, the rotation speed (RPM) of the DC motors (5, 5 ') of the drawing machine (1) and the finishing machine (2) to be driven is detected by the pulse generator (6, 6') and the detected rotation speed (RPM) value And the value calculated by the central processing unit 10 are compared to the comparators (8,8 ').

상기에서 비교된 값에 오차가 검출되면 검출된 오차값을 F/V변환기(9,9')로 보내어진다.If an error is detected in the value compared above, the detected error value is sent to the F / V converters 9 and 9 '.

이때 F/V변환기(9,9')는 주파수를 전압으로 변화시켜 디지탈드라이브시스템(7,7')에 인가하므로 상기 디지탈드라이브시스템(7,7')은 비교기 (8,8')에서 검출한 오차값을 D.C모우터(5,5')에 드라이브하므로 D.C모우터(5,5')는 정상속도, 즉 중앙처리장치(10)에서 계산된 회전속도(RPM)으로 회전하게 된다.At this time, the F / V converters 9 and 9 'change the frequency into voltages and apply them to the digital drive systems 7 and 7', so that the digital drive systems 7 and 7 'are detected by the comparators 8 and 8'. Since the error value is driven in the DC motors 5 and 5 ', the DC motors 5 and 5' are rotated at the normal speed, that is, the rotation speed (RPM) calculated by the central processing unit 10.

따라서 모선재가 최종다이(DIES)를 통과하면 얻고져하는 규격의 신선된 사이즈를 얻는 것이다.Therefore, when the mother wire passes through the final die (DIES), the fresh size of the obtained standard is obtained.

이상의 설명에서와 같이 규격의 신선된 제품을 얻기 위하여 전체다이 (DIES)를 교체하므로서 발생하는 가동율저하와 생산량감소등의 문제점을 개선하여, 전체다이(DIES)의 교체를 일부다아(DIES)교체로서 규격의 신선된 선재를 얻을 수 있으므로 다이교체에 소비되던 시간을 단축하였으며 시간단축으로 인한 가동율 역시 향상됨을 특징으로 한 발명이다.As described above, it is possible to improve the problems such as lowering of operation rate and reduced production by replacing all dies in order to obtain fresh products of the standard, and to replace all dies as part of DIES replacement. It is an invention that it is possible to obtain a fresh wire of the standard, thereby reducing the time spent on die replacement and improving the operation rate due to time reduction.
