CS251858B1 - Under-table saw cover combined with trimming remover - Google Patents

Abstract

The underbench saw cover with chip remover is designed for cutting large-area wood-based materials. It consists of lifting rods on which the cover itself is rotatably mounted. When releasing the cut material, the cover is lifted and tilted at the top dead center using a hydraulic or pneumatic cylinder. After the cover is subsequently lowered to the lower working position, the same cylinder re-aligns the cover, the side of which collects the chips from the saw table.

Description

The invention relates to a cover of an under-table circular saw for cutting large-area materials, ensuring the material is pressed at the time of sawing the machine and the mechanical removal of cuttings from the work table after the cutting is finished.

The prior art undercut saw covers prevent access to the tool itself at the time of its operation, but cut off residues of material, which are sometimes several meters long, are removed manually or separate chip removers are developed.

This in turn increases the cost of producing a cross-cut circular saw and in turn creates complex mechanisms that extend the production cycle and increase machine complexity.

The aforementioned drawbacks are overcome by the undercut saw cover with the combined chip remover according to the invention, characterized in that a sliding cover is mounted above the fixed saw table under which the saw carriage runs and which is rotatably mounted in bearings on the lifting bars. The hydraulic or pneumatic cylinder deflects the cover at the top and aligns it at the bottom dead center of the lifting rods, at the same time cutting off the entire length of the cut to the tilting part of the table.

An example of an embodiment of the undercut saw cover for cutting large-area materials is shown in the drawing, in which Figures 1 and 2 schematically show a front view and a side view of the undercut saw. FIG. 3 shows the position of the cover 4 at the top dead center of the lifting bars 6. FIG. 4 shows the deflection of the cover 4 at the top dead center of the bars 6. FIG. 5 shows the surface of the cover 4 at the bottom dead center of the lifting bars 6; the cover 4 is aligned by the roller 9.

1 and 2, a circular saw 3 is displaceably mounted on the fixed table 1. The saw cover 4 is rotatably mounted in bearings 5 on the lifting bars 6 slidingly mounted in the guides 7. The lifting bars 6 by means of hydraulic or pneumatic cylinders 8 can be lifted into the upper dead center. In this position, the hydraulic or pneumatic cylinder 9 can deflect the cover 4. When locating the lifting bars 6 at the bottom dead center, the cover 4 is aligned by the action of the rollers 9 and the cuttings 11 are moved to the tilting platform 2. The cuttings are indicated by position 12.

After feeding the material to be cut 10, the cover 4 by means of the rollers 8 and the lifting rods 6 pulls down and presses the cutting material 10 to the fixed table of the saw 1. After cutting off the cover 4 by means of the rollers 8 is lifted to the upper position. 8 lower cover 4. The roller 9 straightens the cover 4, which by its side edge summarizes the cuttings 11 on the tilting platform 2. The roller 9 is electrically operated and the blocking of the correct function of the cover is performed in the electrical switchboard.
