Abstract

The invention relates to a technique for ripping wood with circular saws and can be used in multi-blade circular saws with floating saws. The purpose of the invention is to increase the stability of the saws by creating normalized gaps between the saws and the guides. The method of installation of floating circular saws and guides includes alternately putting them on the saw shaft and parallel to it, respectively, and the overall reduction of the saws between the outermost and the outermost guides. Before shrinking, dimensional shims are installed between the saws and the guides, the thickness of which corresponds to the size of the standard clearance. After compression from the regulatory clearance. After crimping with a normalized force, all guides are rigidly fixed, the air-water mixture is fed through them and the gaskets are removed. The device includes a saw shaft 2 with saws 1, a beam parallel to it for mounting guides. The extreme guide is fixed, and a measuring pad 5 is installed between each saw 1 and the guide, the thickness of which is equal to twice the one-sided gap between the saw and the guide. To fix the position of the guides, an electromagnet 7 is installed, which is connected with all the guides of the magnetic circuit. 2 sec. f-ly, 2 ill.

The invention relates to a technique for ripping wood with circular saws and can be used in multi-saw circular saws with flailing saws.

The purpose of the invention is to povazhenie saw resistance due to the creation of normalized gaps between the saws and guides,

Fig, 1 shows a diagram of the device, side view; in fig. 2 shows a section in FIG. 1,

The saws 1, mounted on the saw shaft 2, and guided 3, mounted on the beam 4 with dimensional shims 5, are pre-crimped with a predetermined force, for example, using a screw spring device 6. The fixing of the guides 3 is carried out with the help of an electromagnet 7, connected with all the guides of the magnetic conductor.

Installation method of floating saws

includes the following sequence

First, alternate set of saws 1, guide 3 cases with fixed (relative to the cases) inter saw blades (determining the thickness of the sawn materials to be inserted) and dimensional strips 5 (the thickness of which is equal to the normalized gap between the saw blade and the saw, i.e., about 0.1 5 mm

Then, the intergame pads, measuring pads 5 (defining the size of the gaps) and saws are crimped; rigid fixation with respect to the beam 4 in the installed position of all the bodies of the guides 3 with fixed inter-saw spacers; the supply of coolant to facilitate the removal of the measuring spacers (defining the size of the gaps); and the removal of dimensional pads .5 (for example, when rotating the saws).

In the proposed method, an alternate set of three parts is produced, the interlayer gaskets being stationary relative to the guides of the guides 3, attached to them, while all the bodies are directed directly — they are not compressed and only fixed on the beam L in certain positions that depend on (other things being equal x) on the thickness of the saw 1 and the thickness of the measuring pads 5, which determine the size of the gap between the saw and the intergamer.

The gap should not be adjusted, since it is determined by the thickness of the gauge (about 0.15 mm), which simply needs to be removed from the system.

After installing the floating saws, they rest on rigidly mounted (fixed relative to fixed bodies) inter saw blades.

The use of the proposed method of installing saws ensures the creation of a standard size of gaps between the saws and guides, regardless of the maximum deviations of the saw thickness and increase of the saws stability, accuracy of sawing and the possibility of reducing the saw thickness.
