The present invention relates to a device for preventing deformation and drop guide of a plate in a cutter. More specifically, when cutting a sheet of metal having a thickness of 0.6 mm or less to a standard, the plate is supplied between the upper and lower braces when the plate is supplied. To prevent deformation, and when cut is made, the cut board is lowered on the rear brace while the cut board is guided so that the cut board can fall on the loading table, and the board is cut without deformation and the discharge is efficiently performed. It is to reduce the loss.

In general, a cutter (aka: shearing machine) is used to cut a thin metal sheet of coil thickness of 0.6 mm or less to a certain length or to cut a sheet cut to the first size to a smaller size. .

The cutting machine converts the rotary motion into a linear motion so that the moving blade is installed on the lifting platform of the rod, and the fixed blade is installed on the pedestal, the cutting point of the plate placed on the pedestal is placed on the fixed blade, and the platform is moved by the platform. The blade comes into contact with the stationary blade of the pedestal and descends, cutting the sheet.

In such a cutting machine, when the cutting length is fixed and cut repeatedly, a back gauge for setting the cutting length is installed at the rear point of the pedestal, and the back gauge is moved back and forth to stop the supply when the plate material touches the back gauge. Will be performed.

Since the back gauge has a thickness of 0.6 mm or less and a cut length of 30 cm or more is supplied to the plate, deflection occurs. Thus, the back gauge is moved together with the plate to stop the cut at a set point, or the utility model As in registration No. 289865 (Registration Date: 2002. 09. 06.), a fixing rod is provided on the back gauge, a cylinder is installed on the fixing rod, and a deflection preventing plate is connected to the end of the cylinder. The cutting work is performed while the plate is protruded and placed on the deflection prevention plate to support the deflection plate, and the cut plate falls when the deflection prevention plate protruding from the scaffold of the back gauge is retracted and discharged along the inclined plate. Means have been known to prevent sagging, but if the means is also more than 1 mm and less than 30 cm in length, steel sheet is possible, but 0.6 mm Of a thin plate material, if the length is more than 30cm and not possible to eliminate the occurrence of deflection of the plate material, and this is deformed and curved cutting the plate material is hit on the floor in the process of falling deformation while the plate material is cut.

Because of this, when the thickness of the plate is less than 0.6mm and the length is cut to more than 30cm, the two or more workers hold the plate so that the plate does not sag before and after the cutter, and the cutting is performed by placing the plate at the cutting point. As a result, defects are exposed to safety accidents during cutting operations, and precise cutting operations are difficult and efficient operations cannot be achieved.

Accordingly, the present invention eliminates the conventional drawbacks and is provided with an upper brace on the upper portion of the rear, the lower brace on the lower side is supplied with a thin plate of 0.6mm or less, the back brace on the upper brace, the support shaft of the lower brace It is an object of the present invention to provide a means for preventing deformation of the plate material in the cutter and efficiently guiding the discharge when the cutting operation is provided by the drop guide means.
