CS257389B1 - Device for increasing the pressure of the black slide, especially for horizontal cutting machines - Google Patents

Abstract

The device solves the arrangement of elements in such a way that magnets are placed in the side panel lining, which is firmly attached to the cutting support and moves on the stand. The purpose of the solution is to increase the pressing force of the cutting support without increasing its weight.

Description

BACKGROUND OF THE INVENTION The present invention relates to a device for increasing the pressure of a gray slide, especially for horizontal edge machines. The currently known cutting machines are designed so that the gray slide moves on the stands mostly by means of a cucumber mechanism. The cut on the table moves against the slim slide. In front of the knife, which cuts the veneer sheet out of the cutout, there is a push bar which pushes the surface of the cutout with the weight of the blanket and allows a smooth cut and a quality surface of the cut veneer sheet. With increasing demands on the power of the slicing machines, the weight of the cutting carriage was reduced to reduce inertia forces that act on the noise mechanism at dead centers and sudden braking. The machines described have difficulty in cutting hardwoods and sticks.

The thickness of the veneer sheet varies and the quality of the veneer surface is insufficient. These drawbacks have also been eliminated on some machines by means of hydraulic cylinders whose piston rods are hinged on the cutting support and the cylinders are anchored to the stand. The cylinders arranged in this way press the gray slide onto the stands. During the two-shift operation of the machine, the machine takes about 50,000 strokes per day. Since there are two strokes of the piston rod per stroke of the machine, the lifetime of such devices is considerable and requires heavy maintenance.

The above-mentioned drawbacks are largely eliminated by the cutting support pressure boosting device of the invention, which is based on the fact that magnets are mounted in the sidewall lining firmly attached to the blank support and movable on the rack. An advantage of the device provided with a magnet is that the magnets increase the pressing force of the cutting slide without increasing its weight, thus without increasing the effects of inertia forces. The magnets are permanently non-energy-intensive and require virtually no operation or maintenance. An exemplary arrangement of a device for increasing the pressure of a gray slide is shown in the accompanying drawing, wherein FIG. Is a cross-sectional view of the stand and sidewall.

The stand 1 is the basic supporting structure of the cutting machine. In the upper part there are sliders 2. The side support 7 includes sidewalls 3 which are connected to it by the couplers 8. At the bottom of the sidewalls 3 the screws 5 are fixedly fastened to serve to reduce friction between the blank support 7 and the sliders 2 of the rack. Magnets 6 are fixed in the lining 4. When the veneer sheet is sliced, the side support 7 with sidewalls 3 is lined 4 by the sliders 2 of the fixed stands 1. Because both the sliding rails 2 and the stands 1 are of magnetic material, the magnets 6 attract the gray support 7 to the stand 1 thereby increasing the weight force induced by the mass of the cutting carriage 7 on the stand 1.

This strength boosts the ridge of the cut veneer sheet as well as the smoothness of its surface, even when cutting hardwood and arhodes.

The device is designed to improve the work of veneer cutting machines. It will therefore be used primarily in the timber industry and timber manufacturers.
