    In a cutting table for sheet metal and the like, the portion of the work that overhangs the table where it is cut is supported on a traveling adjustable support (9) having rollers on its upper surface. As the upper blade is brought down to cut the work progressively from the side near the pivot of the blade to the opposite side, a traveling carriage on which the traveling support is mounted is caused to move along the length of the cut so that it provides support to the work at the location where the blade is doing the cutting. The support is pivoted on an axis perpendicular to the cut so that it can adjust itself to the inclination of the upper cutting blade, the pivot being fixed on a vertically slidable member guided in the carriage. Hydraulically driven pistons enable the support to be raised or lowered with respect to the carriage. Wide cuts can thus be made without the strip that is cut off being twisted, coiled up, or otherwise deformed.

    The invention relates to the processing of metals by pressure, namely cutting, and can be used for cutting metal sheets and similar material.
    The purpose of the invention is to improve the quality of the blanks obtained by cutting the sheet by improving their geometric shape.

    A device for cutting metal sheets and the like material comprises a bed 1 with a table 2 for displacing the metal sheet being processed. On the table 2, the lower knife 3 is fixedly mounted. The movable knife 4 is fixed on the cutter beam 5 of the device with the ability to interact with the lower knife 3 at a determined cutting angle. Under the knife beam 5 with the ability to move along the lower knife 3 along the guide 6,

    on the frame 1, having installed the upper knife 4, during the cutting process, cuts the edge of the metal sheet located on the right (FIG. 1) and presses the protruding part down to the support 9. The support 9 is thereby progressively pressed down, while a certain predetermined counter pressure is created in the power cylinders . This counterpressure provides the necessary support and clamping of the metal sheet in the deformation zone. Simultaneously with the pen

The axis of the hinge 11 is located in the plane of symmetry of the support 9 perpendicular to the plane of the cut. Guide 10 is installed with the possibility of vertical movement in the carriage 7, the raising and lowering of the support 9 is carried out with the help of two axles 12 and 13, installed on both sides of the guide 10, which move in the corresponding power cylinders mounted in the carriage 7, Both power the cylinders are connected to the same working medium circulation system under pressure, so that the support 9 makes its own rotation around the axis of the hinge 11 regardless of the clamping force effected by force chi Lindra. Rollers 14 are mounted on the upper surface of the support 9, the axes of the rollers 14 are arranged perpendicular to the plane of the cut and parallel to the axis of the ball joint 11, as a result of which the rollers can move under the sheet being cut when moving the carriage 7. Rollers 14 do not serve
    only to protect the cut strip of the metal sheet from deformation, in particular against twisting, but they also cause intense alignment and smoothing of the metal sheet.
    The device works as follows.
    The metal sheet to be cut is placed on the table 2 of the device, ensuring that the desired cutting line coincides with the cutting edge of the lower knife 3, while the carriage 7 is in its extreme position. Its support 9 is raised up so that it is adjacent to the underside of the metal sheet,
    During the cutting process, the upper knife 4 cuts the edge of the metal sheet located to the right (Fig. 1) and presses the protruding part down to the support 9. The support 9 is thereby gradually pressed down, while a certain predetermined counter-pressure is created in the power cylinders. This counterpressure provides the necessary support and clamping of the metal sheet in the deformation zone. Simultaneously with re 5

In synchronization with this, the carriage 7 moves from right to left, as a result of which the support 9 always remains in the deformation zone of the metal sheet. Due to the hinge on the guide 10, the support 9 takes the position corresponding to the cutting angle. The cut strip of the metal sheet is removed by an ejector (not shown) interacting with the support or by tilting the support.
