Abstract

Invention applies in the field of construction and is being used for floor laying and finishing. The machine has two circular (1,2) saws and a driving shaft. One cross-section timber cutting saw is attached to the driving shaft (1) and the other saw (2) has hard-metal plates on its cogs. The flooring panel consists of cross-section floorboards (10) glued to a base layer. The floorboards (10) are polygon shaped with straight sides. The floor panel is covered by eight-angular (12) and square (13) floorboards. Round thin timber is cut by a double-saw machine into round cuts as thick as the floorboard that are being formed by pressing into the eight-angular (12) and square (13) floorboards. Floorboards (10) are being glued to the base (9) by an irregular side that is formed by cutting with a cross-section saw (1). Gluing to the rough surface an adhesion makes it stronger and improves floorboard quality. The other side of floorboards, the on e cut by the saw with hard-metal plates on its cogs is right away made even, good quality even without intensive polishing, and therefore production of the floorboards is simplified.

Description

The invention relates to floor laying and finishing.

A known circular saw wood sawing unit having two parallel-mounted saw blades with a circularly mounted circular saw blade arranged in a single plane, a saw guide and a feed shaft. The guide rails are mounted on a base and positioned between the saws so that each pair of saws mounted on different shafts is • located in one pair of guide rails. Feed rolls and guides are spaced to pass a person (see Former USSR Certificate # 1395486, B27B5 / 34, I.B. No.18, 1988).

Also known is a wood cutting unit having a base, a shaft with axially movable circular saws, guides having a body with inserts movable parallel to the axis of the shaft. It also has a device for pumping lubricant-coolant into the gap between the saw and the insert and a screw to press the insert into the base. Inserts in the guide housing Equipped with additional degrees of freedom for the vertical axis of symmetry and horizontal axis of symmetry for the saw blades. A rigid element is inserted between the clamping screw and its adjacent insert (see Former USSR Auth. No. 1074717, B27B 5/34, I.B. No. 7, 1984).

Also known is a parquet panel * glued to a free cross-section of parquet boards of the selected species of wood. - The spaces between the parquet boards are filled with circular wood inserts inserted into the holes made in the base and between the parquet boards (see Former USSR Certificate No.1642957 ONLY EO4F 15/04, I.B. No.14, 1991) ..

The disadvantage of the known cutting unit is the poor quality of the parquet board, because after cutting, both sides of the parquet board are the same and its top finishing surface needs a lot of ironing and sanding, which is a complicated, energy-intensive job.

*

The disadvantage of the known cross-section of parquet boards is its poor quality, because the parquet boards are made of natural round wood cuts and the spaces are irregularly filled in circular intervals.

The object of the present invention is to simplify and facilitate the preparation of parquet boards and to improve the quality of the parquet.

The stated objective · is achieved by:

1. The following changes have been made to the known twin-blade sawing machines with two circular saws and a drive shaft: one transverse saw is attached to the drive shaft and the other with hard metal plates on the teeth:

2. In a known parquet panel of cross-sectional parquet boards consisting of parquet cross-sectional parquet boards glued to the base layer, the following modifications have been made: the parquet board is made of polygonal lorms with straight polygonal sides, the panel consists of octagonal and square parquet.

BRIEF DESCRIPTION OF THE DRAWINGS The invention is explained in the drawings, wherein * FIG. Figure 1 is a front view of the shoulder strap; 2 - Machine from above, fig. 3 - Parquet panel from above, fig. 4 parquet panel on the side.

The two-blade circular saw has two circular saws 1,2 and a drive shaft (not shown). One transverse saw blade 1 according to GOST 9806 is pushed and fixed on the drive shaft; code 07540450; 400x2.2. The second spindle, mounted on the spindle 2, has hard metal plates on the tooth cutting surface for direct and direct cutting. This saw 2 conforms to GOST 9769-69; code 0754150; 400x2,8. Saws 1 and 2 are mounted '5 on the same shaft parallel to each other. The machine 'has a movable table 3 with a device for securing sawn timber 4 in the form of a chuck 5. The gripper 5 is fixed to a movable plate 6 mounted on a. movable table 3 with the possibility of moving in a fixed step.

perpendicular to the '1.2 planes of the saw. The movable table 3 is arranged in the guide 7 parallel to the planes 1,2 of the saw. ' The moving plate 6 is placed in a path perpendicular to the planes 1,2 of the saw. Parquet panel has glued to the base layer, parquet boards 10.

Parquet boards 10 are made of cross-section wood panels with regular polygons with straight sides 11 shape. The panel is made of parquet boards having the shape of octagon 12 and square 13. The sides 11 of the octagon 12 and the squares 13 are of equal length and are clamped together in the panel.

The present invention is accomplished as follows:

The used wood 4 is fastened by means of clamps 5 to the movable lathe plate 6. By sliding the table 3 in the direction of saws 1.2, the parquet board is cut. 10. The cross-cut saw 1 cuts the parquet board 10 unevenly and roughly on one side. On the other side, a saw with hard metal panels on the teeth parquet board

10 cuts exactly. The table 3 with the wood 4 is then pulled back from the saws 1,2, and the plate 6 with the wood 4 makes one fixed step in the direction of the saws 1,2, perpendicular to their plane. Yes wood. 4 is moved to the cutting position for the next cut. Table

3 pushing again towards saw 1,2, the cut is repeated.

In this way, repeating the displacements of the panel 6 and the table 3, the wood 4 is cut into parquet board cross-sectional slabs for parquet boards 10. With a press body having a working body corresponding to octagonal 12 and square 13, octagonal 12 <and square 13 , parquet boards 10.

When making a parquet panel, the parquet boards 10 are unevenly cut with a cross-cut saw 1, glued to the base layer 9. The spaces between the octagonal parquet boards 12 are filled with square parquet boards.

13. The top layer of parquet consisting of '10' side of the parquet boards, sawn with sawdust 2 panels, is punctured and sanded after gluing.

Compared to the prototype, the proposed solution simplifies and facilitates the preparation of parquet boards and improves the quality of the 15 parquet boards. The cross-cutting saw cuts the parquet boards roughly and without any additional preparation, which simply and strongly adheres to the substrate. The uneven surface adheres to a stronger, better quality. With a solid-wood saw 20, the surface is smooth and requires little sanding once the 'parquet' panel has been prepared. This simplifies parquet preparation and improves its quality. Compared to the prototype, parquet preparation is facilitated by the return of its panel and filling in the spaces.

formed from v- pre-prepared parquet boards. This reduces labor and improves the use of wood by utilizing non-circular round wood presses, leaving little waste. * I.r completely thin wood is used for square parquet boards.
