Description

. The present invention relates to the installation of saws in a frame sawmill and is aimed at improving clamp plates, clamping the installation of the saw set and presenting simple rectangular tiles in existing installations. Instead of the previous rectangular pieces of wood, having the thickness required by the sawblade, it is proposed to introduce a previously known metal bead of steel with the appropriate thickness required, looking at the board's assortment, since the wooden parts used at most of the factories are partially affected and changes in their sizes are thrown out of disrepair, but partially fall into the sawdust conveyors when they are rearranged and taken away. Replacing wooden parts with more advanced metal ones is aimed at significantly speeding up the rearrangement of the saw set and destroying the waste of material and labor time.

FIG. 1 of a schematic drawing shows a general view for installing saws in a sawmill frame; FIG. 2 is a section through it in line AB in FIG. one; FIG. 3-section

along the line EF in FIG. one; FIG. 4 and 5 is a section along the line of the LED in FIG. 1 two types: metal parts with a circular and rectangular hole.

For the installation of saws in the frame of the sawmill, box-shaped metal parts A, corresponding to the required dimensions, are introduced (Figs. 4 and 5). equipped with two ears, B in which the hole is made in part circular 1, rectangular part 2. Different types of ears B (Fig. 4 and 5) are given parting A so that, firstly, parting A can freely be on the bar 5 in a hanging position and, secondly, so that when the unit is installed, it can be installed in a horizontal position to secure the saws. In view of the fact that the separations are made of thin steel, their weight is insignificant, and therefore no effort is required when installing the separations A between the saws 12. The bar 3 is located in the recesses 4 on the plates 5 (Fig. 2) of clamps 5-9- U is fixed, after insertion, with the aid of spring-loaded latches L (Figs. 1 and 2).

Plates 5 clamps, clamping the installation of a saw set, have in its lower part. Grooves slits 6,

in which the stroke stop screws 7 fastened to bar 6 placed also in slot 6, whereby the fastener is made so that when turning screws 7 bar 8 could advance along the length of the slot 6 of the plate, 5 (Fig. 2) , in order to move the bar 8 of the entire group of saws 12 to set, report these saws as required, in accordance with the installation; the value of the supply of wood, overhang.

This improvement in clamps makes it possible to mechanically set the inclination of the saw blades IS, without resorting to measuring instruments, since the slit size is applied near the notch 6, and the moving bar 8 can be precisely set to the corresponding saw slope 112.

The whole work of relocation is set up as follows: first of all, they are changed and fastened, the newly inserted machined saws are inserted into the square holes 4 of the upper part of the clamping plates 5 and locked with spring clips 11 square bar, on which Forward, the required set of parts A for this set is recruited, then parts A are moved from the vertical to the horizontal position, rotating on the bar 3 circumferentially, and at the moment of pressing the lower part of the parting to the bar S, which serves The tilt saw blades 12, the partitions Af come in exactly horizontal position, are inserted into the rectangular part S of the ear B and remain hanging in that position. When all the parts A are thus placed between the saws 12, the clamp screws 9 are all clamped between the extreme bars f.5,10 of the clamp and the saws are tensioned, after which the set is completed.

The subject matter of the invention.

A device for installing saws in the frame of a sawing machine with the use of box-shaped metal parts, characterized in that the parts A (Figs 4 and 5) are equipped with ears B, the holes in which are made partly circular, partly rectangular 2, in order to suspend the partitions loosely or keep them in a horizontal position on bar 5 (figs. 1 and 2) fixed with latches L in recesses 4 on clamps 5 of clamps 5-9-10, which plates 5 from the other end are provided with 6 slits for dl placing bar 8 moving action it stop screws 7, the purpose of the entire group Moving the update them saws 12 hocked to impart these desired saws in accordance with the set of feeds wood overhang.
