The present invention relates to an ultra-thin coil strip tip progression apparatus, which is manufactured by rolling the end of the coil strip in the form of a corrugated plate in the longitudinal direction in a manufacturing process for rolling a minimum thickness of a cold rolled product, thereby making it possible to achieve a good mailing work. The present invention relates to a foil coil strip tip running device.

1 schematically shows a conventional method of operation, in which the leading end 3 of the ultra-thin (0.1t-0.05t) coil 6 strip passes through the lower and upper bridal rolls 2 and the upper press roll ( 1) and then proceeds to the pinch roll (5), the front end portion (3) as shown in the example of the overlapping phenomenon occurs on the table, so the mailing operation is not made, so each section is pulled by using the tool to advance to the exit side .

However, there are many problems with this method of operation.                         

That is, firstly, the mail order work takes too much time and the work load of the worker is increased, which lowers work efficiency and productivity.

Second, there is a problem that causes safety disasters due to the proximity of facilities and the implementation of a lot of manual work.

The present invention has been made in order to solve the conventional problems as described above, and proceeds by processing the end of the coil strip in the form of a corrugated plate in the longitudinal direction, install a concave-convex table to minimize the contact portion with the back surface of the strip, and It is an object of the present invention to provide a device capable of bending the uppermost end of a strip to allow a good mailing operation of the coil strip to be made and to provide a leading end device of the ultra-thin coil strip capable of preventing a safety hazard.

Hereinafter, with reference to the embodiments illustrated in the accompanying drawings, the present invention for achieving the above object will be described in detail.

Fig. 2 is a perspective view of the ultra-thin coil strip tip running apparatus according to the present invention as a whole, and Figs. 3 and 4a, 4b and 4c are detailed views of the main parts of the apparatus.

Referring to the configuration of the present invention with reference to the drawings, the uneven table 16 has a plurality of protrusions are formed on the upper surface in order to minimize the contact with the back of the iron plate is fixed to the lower support block (9a, 9b) have.

The main body rotation shaft 27 is rotated by 90 degrees by the hydraulic motor 13, and the moving device body is engaged with the swing arm 14 and the key, but the upper bending punch 10 is not interlocked. A stopper 15 is provided for limited rotation of the swing arm 14.

Rotation of the upper forming roll 20 is made by a drive motor 12, it is composed of a universal joint 25 and the spline 26 for smooth operation with the main body rotated 90 degrees, the upper forming roll 20 The support is assembled and supported by a bearing block 19 embedded under the swing arm 14.

The screw 18 is configured to move up and down by the rotation of the adjustment nut 17 which is a fine adjustment device so that the corrugated plate depth can be adjusted according to the thickness.

The lower forming roll 21 is idle rotated, and the material is polyethylene to prevent scratching of the iron plate and is fixed to the lower support blocks 9a and 9b.

The lower bending punch 11 is fixed to the lower support blocks 9a and 9b, and a triangular groove is dug in the transverse direction at the center.

The raising and lowering of the upper bending punch 10 is operated by both air cylinders 22, and the punch portion is configured to rise and fall into the lower bending punch 11 grooves in a convex triangle.

In operation, the coil strip tip 3 passes between the upper bridle roll 2 and the upper press roll 1 and proceeds onto the uneven table 16, wherein the upper forming roll 20 is lowered and thus the upper portion. The forming roll 20 and the lower forming roll 21 are rotated together.

Accordingly, the coil strip distal end portion 3 passing between the upper and lower forming rolls 20 and 21 is formed with corrugated irregularities in the longitudinal direction as shown in FIG. 5, so that strength is imparted in the traveling direction. When the coil strip tip 3 passes through the uneven table 16 and passes about 50 mm over the lower banding punch 11, the roll drive stops, and then the upper banding punch 10 is lowered to lower the leading end of the strip. By letting the upper portion of the coil strip front end (3) again, even if it passes through the portion having a fault plate failure easily.

If the coil tip 3 is properly progressed in the state where the corrugated irregularities are formed, then the pinch roll 5 is lowered to advance to the desired position, whereby a good mailing work condition is achieved.

The rise of the main body can be heard while rotating 90 degrees by rotating the counterclockwise direction with the hydraulic motor 13 at an appropriate time.

As described above, in the present invention, when the thin coil strip is mailed, the coil strip tip part is processed into a corrugated plate shape, and the uppermost part is pushed upward to proceed smoothly, thereby shortening the mailing work time. It improves efficiency and minimizes manual work, thereby reducing the work load of workers and inducing the problems of safety accidents.
