Abstract

PURPOSE:To prevent curving or flaw from generating at an end of a slit coil in a swinging type outlet side cutting device for slit coils by forming the device so as to swing freely with respect to the upper end base of an outlet side shear arranged at the outlet side of a deflection roll, and connecting the deflection roll to a cylinder by means of a link. CONSTITUTION:A lower base 4 of an outlet side shear 2 provided at the outlet side of a deflection roll 1 is mounted on a stationary base 3 swingably by means of a pin 5. A bracket 8 is provided at the top of the shear 2 and connected by a rod 11 of a cylinder 6 provided at the top of the deflection roll 1 and a pin 12, and the deflection roll 1 and the shear 2 are connected by a link 7. With such a construction, the shear 2 is swung in a flow direction by means of the cylinder when an upper blade 10 is raised to escape the shear 2 in the flow direction by an amount (a) in the Figure, thereby preventing a slit coil end from striking against a side of the upper blade 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outlet side shear provided on the outlet side of a deflector roll in a slitter line to cut the slit coil.

[0002]

2. Description of the Related Art Conventionally, when a slit coil is cut by a delivery-side shear, the upper and lower blades are engaged with each other.
In this case, the lower blade was fixed and the upper blade moved up and down and cut, but since the slit coil is flowing continuously, the slit coil flows even after the slitting coil is cut and the upper blade moves up. The slit coil end cut while the upper blade was rising and escaping abutted against the side surface of the upper blade, and the end of the slit coil end was bent or scratched, or the blade was damaged, causing a problem.

[0003]

The problem to be solved by the present invention is to prevent the tip of the slit coil, which flows while the upper knife is rising after cutting with shears, from hitting the side surface of the upper knife. This is to prevent bending and scratches at the ends of the slit coil.

[0004]

According to the present invention, when the slit coil is cut by a shear, the tip of the slit coil does not hit the side surface of the upper cutting tool immediately after cutting.
At the same time as cutting, the upper and lower shear blades are configured to escape in the flow direction of the slit coil, so that the end of the slit coil does not hit the side surface of the upper blade during rising.

[0005]

The lower portion of the shear is swingably connected to the fixed base by the pin, and the upper surface of the shear is connected to the rod of the cylinder provided on the upper surface of the deflector on the shear machine side to operate the cylinder. The shear is swung in the flow direction of the slit coil to prevent the end of the slit coil from contacting the side surface of the upper cutter.

[0006]

EXAMPLE A fixed base 3 of a shear 2 is provided on the exit side of the deflector roll 1, and the base 3 and the lower base 4 of the main body of the shear 2 are connected by a pin 5.

On the other hand, a bracket 8 is provided on the upper surface of the main body of the shear 2 and a cylinder 6 provided on the upper surface of the deflector roll 1.
The rod 11 and the pin 12 are connected, and the link 7 connects the deflector roll 1 and the shear 2.

When the present invention has the above-mentioned structure and is cut, the conventional one shown in FIG.
While 0 rises, it hits the side surface and the tip bends as shown in FIG. 2B. However, when the cylinder 6 is actuated to swing the shear in the flow direction, a in FIG.

[Formula 1] However, if the upper blade rises within the time during which the slit coil flows, the end of the slit coil will not hit the side surface of the upper blade.

[0009]

As described above, the present invention can achieve the original purpose at a low cost, particularly in the line of high-grade materials such as surface-treated steel plate and color steel plate, only by providing the pin connecting portion, the cylinder and the link. It is a good invention.
