A holder support connected to a lower end of the hydraulic cylinder and the cylinder auxiliary rod, and having a drive motor installed thereon;

An upper pressurized rubber roll holder fitted to the holder support and having an air cushion cylinder embedded therein and having a base formed at a lower portion thereof and moving along the screw direction of the shaft;

A lower pressurized rubber roll holder fixed by the upper pressurized rubber roll holder and a fixing pin, the hammer being fitted on the fixing pin, and having a rotary cam and a pressurized rubber roll installed therein;

A spring mounted between the hammer and the base and whose length is adjusted by a tension adjusting bolt;

It is connected to receive the driving force of the drive motor 74 by the time belt 72, and includes a shaft 56, the left and right screws are formed to move the upper pressure rubber roll holder 52a in the screw direction It is achieved by providing a coil edge flat pressing device characterized in that the configuration.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

3 is a perspective view of the coil edge flat pressing device according to the present invention, Figure 4 is an exploded perspective view of the coil edge flat pressing device according to the present invention.

According to the figure, the hydraulic cylinder 80 and the cylinder auxiliary rod 78 is fixed to the cylinder support portion 82 and the lower portion of the hydraulic cylinder 80 and the cylinder auxiliary rod 78 is fixed to the holder support 76. Connected.

A drive motor 74 is installed as a driving source on an upper side of the holder support 76, and the drive motor 74 and the shaft pulley 70 are connected by a time belt 72.

The shaft 56 is connected to the shaft pulley 70, and the shaft 56 is formed by being divided into a left screw and a right screw.

The upper pressurized rubber roll holder 52a is inserted to move along the respective screw direction formed on the shaft 56 and is installed to be movable to the holder support 76 on one side.

An air cushion cylinder 58 is mounted in the upper pressurized rubber roll holder 52a, and a lower pressurized rubber roll holder 52b is fixed by a fixing pin 69 in the lower portion.

A base 66 is formed between an upper portion and a lower portion of the upper pressurized rubber roll holder 52a, and the hammer 60 is inserted between the portions connected by the fixing pins 69 so as to be movable.

The hammer 60 and the base 66 are connected by the tension adjusting bolt 62 from the top of the base 66 to the top of the hammer 60 so that the spring 62a is installed therebetween.

The rotation cam 68 is installed in the lower pressurized rubber roll holder 52b in connection with a cam wheel 68a installed outside the lower pressurized rubber roll holder 52b and is symmetrical with the fixing pin 69. The pressurized rubber roll 50 is installed inside.

The pressurized rubber roll 50 is connected to a pressurized rubber roll rotating wheel 50a installed outside the lower pressurized rubber roll holder 52b, and the pressurized rubber roll rotating wheel 50a is connected by a belt 72a. do.

The operating relationship of the present invention made of such a configuration is as follows.

As shown in FIG. 5, when the coil insertion of the payoff reel 10 is completed, the device according to the invention is lowered by the hydraulic cylinder 80.

At this time, the strip 1 having the coil edge ear damage defect 100, such as edge stamping, bending, and cutting of the outer coil portion, generated during the transfer of the raw material coil, proceeds and rotates the pressurized rubber roll 50 lowered thereto. Let's go.

At the same time, the rotational force of the pressurized rubber roll 50 is transmitted to the pressurized rubber roll wheel 50a as shown in FIG. 4 and the transmitted power is transmitted to the cam wheel 68a by the belt 72a again.

In addition, when the rotary cam 68 is continuously rotated by the rotation of the cam wheel 68a, the hammer 60 repeatedly raises and lowers continuously and through this process, the coil edge ear damage defect 100 is primarily. Will be hit.

At this time, the operator can adjust the strength and weakness of the strength by adjusting the tension adjusting bolt 62 of the spring 62a according to the striking strength of the hammer 60.

Subsequently, when the coil edge ear damage defect 100 passes through the pressure rubber roll 50, the pressure rubber roll 50 secondaryly pressurizes the coil edge ear damage defect 100 to damage the surface of the strip 1. This is avoided.

As described in detail above, according to the present invention, when the pay-off reel rotates, the coil edge ear damage defect occurs during the first and second flat operations. By preventing the surface damage of the cotta roll, it is possible to eliminate the end of the early roll change due to the roll damage. As a result, it provides the highest quality products to the consumer, resulting in increased work efficiency and increased productivity.
