Title: Controller for cutting top end of wire rod
Inventor: TANABE TADASHI
IPC: B23D36/00
Filed: 1989-12-20
Abstract: PURPOSE:To secure accuracy of cut length and to prevent the danger of erroneous roll by providing a wire rod position sensor for calculating the top end position of the wire rod, a shift timing calculator for supplying a shift signal to a guiding device, and a shear speed correction device for correcting a shear speed. CONSTITUTION:There are provided a wire rod position sensor 7 and a shift timing calculator 8. The wire rod position sensor 7 calculates the position of the top end of the wire rod 1 and the shift timing calculator 8 supplies a shift signal to a guiding device 4 when the calculated position of the top end of the wire rod 1 is located before the cutting point of a shear 3 by a length obtained by subtracting a required cut length from traveling length within a predetermined shift motion delay time. Predetermined calculations are repeated according to the top end position of the wire rod 1 and the rotational angle of a shear cutting edge so as to correct the speed of the shear by a shear speed correction device 11 so as to place the cutting edge of the shear 3 at a bottom dead center when the guiding device 4 is shifted to the cutting position of the shear 3. The accuracy of the cut length is thereby improved, and also the generation of erroneous roll due to erroneous cutting is prevented.
