The present invention relates to a strip edge portion separating device of a coil-like thin plate, more particularly, to simplify the operation of hitting the trumpet portion generated in the edge portion of the thin plate coil to prevent damage to the edge portion as well as to protect workers from industrial accidents. The present invention relates to an edge separator of a coiled thin plate.

In general, the cold rolled hot rolled coil is subjected to the annealing process in a number of annealing furnaces, and in particular, the oriented electrical steel sheet has its own unique characteristics only through the hydrogen annealing furnace.

The grain-oriented electrical steel sheet is subjected to secondary annealing in a continuous annealing line, coated with magnesium oxide on the surface, and vertically charged into the tunnel-type annealing furnace, followed by annealing at high temperature for a long time to be annealed into a thin plate having a directionality.

When the annealing is completed as described above, the coil-shaped thin plate is removed while the magnesium oxide coated on the surface of the thin plate is removed, and then passed through the tunnel-type annealing furnace to perform annealing.

 As shown in FIG. 1, while the coil-like thin plate is vertical tunnel-type annealing, the coil 1 is vertically seated on the base plate 3 to be subjected to high temperature annealing for a long time. At this time, the coil plate is closely adhered to the base plate 3. The edge portion 2 of the coil-like thin plate was subjected to an edge shape defect due to a poor strip winding and a magnesium oxide coating defect portion to be pressed against the coil 1 load on the surface of the base plate 3 for a long time at a high temperature, thereby causing the coil edge portion to trumpet. It is formed in a shape so that the coil edges of the thin plates stick together.

Then, as shown in FIG. 2, the worker separated the strip edge overlap while hitting the edge portion 2 of the thin plate wound on the coil 1 with a hammer 4.

However, such a conventional work is very dangerous because the worker approaches and directly hits the coil-shaped thin plate, and the magnesium oxide that has been coated on the surface of the thin plate is scattered and flows into the worker's hopper to generate an industrial accident. There was a problem.

In order to solve the above problems, the present invention continuously removes the overlapped portion of the trumpet-shaped coil in the form of a coil by vertical annealing and the portion where the strip edge adheres due to a poor magnesium oxide coating, and forcibly coils the edge portion.

As shown in Figs. 3 to 5, when the driving cylinder 6 is operated downward, the strip edge separating device of the coil-like thin plate attached thereto adjusts the height of the coil 1 while moving downward.

In addition, the upper and lower rack bar (7) installed in the drive cylinder (6) is engaged with the pinion gear (8) and narrowed inward to match the width of the strip (5).

At this time, before the two strip edge separating devices advance toward the width of the strip 8, the upper and lower hunting rolls 28 and 29 are aligned by the position sense detector attached to the roll housing 27 so that the motor ( 9) is driven.

Work is started by strip sensing sense sensing at the working position of the strip edge separator of the coiled sheet.

As shown in Fig. 4 and 5, first, the motor 9 of the power unit is driven to rotate, at which time the spur gear wheel 11 received the rotational power is rotated, so that the wheel connecting member 12 is operated up and down While converting the forward and backward reciprocating energy through the operating link 13 transfers power to the hunting device and knife 18.

The sliding rack 14 of the knife 18 and the upper and lower pinions 16 and 17 reciprocate back and forth, and swing the lower edge bite of the coil edge from the inside to the outside with the knife 18. At this time, the overlapping portion of the trumpet wound in the coil form and the strip edge portion due to the magnesium oxide coating defect are primarily separated.

In addition, according to the operation of the operation link 13, the forward and backward operation of the operation rod 22 is made, and the spring 21 in the center of the operation rod 22 is always constant to the upper and lower tension hunting rolls 28 and 29. The tension is maintained on the strip 5.

In addition, after adjusting the length of the male screw portion 24 to adjust the hunting amount of the upper and lower hunting rolls 28 and 29, it can be fixed and fastened with a fixing nut 25.

Up and down hunting rolls 28 and 29 operate while the roll housing 27 rotates left and right by receiving power of the reciprocating action of the operation rod 22 directly.

As shown in FIG. 6, the upper and lower hunting rolls 28 and 29 rotate left and right to stress the strip 42.

In addition, the upper and lower hunting rolls 28.29 are symmetrically inserted into the strip 5 edges with respect to the fixed shaft 30 holding the central axis of the roll housing 27 in a symmetrical manner so that the edges of the strip 5 are raised and lowered. While hunting, as illustrated in FIG. 5, the coil bite lower surface 41, which is a portion where the trumpet-shaped overlapping portion and the strip edge adhered due to a magnesium oxide coating defect, is subjected to strong stress and separated secondarily.

After the above operation, the position of the strip edge separating device of the coil-like thin plate is lowered by the calculation of the coil rotation speed of the cylinder 6 of the strip edge separating device of the coil-shaped thin plate according to the decrease of the coil diameter due to coil unwinding. It can be compensated automatically by the diameter reduction of the outer coil.
