The method includes simultaneousmaking of the required number of woodworking cutting operations bypreset lengths along the whole length of the timber, and at thesame time the layer is also cut horizontally. The device for theimplementation of the method includes a pair of rests to whichhorizontal (3) and vertical (5) disc saws are fitted driven bymotors (4).

Description

Technical field

The invention relates to a method for longitudinal processing of timber, which is independent of the diameter and length of the material, and a device for carrying out this method.

BACKGROUND OF THE INVENTION

A device for longitudinally cutting logs with two circular saws or a circular saw is known. The saws are arranged one above the other in a common plane of cut. This allows the cutting of logs of large diameter, but only in one plane.

A device for longitudinally slicing logs by cutting into several planes with a circular saw system is also known. However, it is not possible to set the thickness of the cut part and to obtain, for example, adjustable-sized prisms.

There is also a device for cutting wood with circular saws in horizontal and vertical planes, which allows cutting in both planes. However, this device does not meet the requirement of maximum versatility and can be processed with a limited width - up to 20 cm.

SUMMARY OF THE INVENTION

The aforementioned disadvantages are avoided and these problems are solved by a method of longitudinal woodworking and a device for carrying out the method according to the invention. The method is based on the principle that the required number of cuts with a given depth along the entire length of the timber is made longitudinally on the timber from above at one time and at the same time the cut layer is cut horizontally. After cutting a set thickness in one plane, the thickness is set to another layer and the procedure is repeated.

The apparatus for carrying out the method of the invention includes a steel structure in which a support carrier is moved in a vertical direction. The four supports are mounted on the carrier as follows: the axes of the vertical disk saws are mounted on two supports on the right side of the carrier, and the axial supports of the horizontal disk saws are located on the left side. The horizontal disk saws are riveted to special dies, fixed to the shafts of the drive motors.

The procedure according to the invention allows to increase the cutting accuracy with perfect workpiece processing, modifications and high productivity.

The horizontal saw blade fixing method is very rational and allows for quick assembly and disassembly.

FIG. 2 is a side sectional view showing the attachment of horizontal circular saw blades to the special die and to the drive motor shaft.

Examples of implementation

The device according to the invention includes a circular saw, which consists of four supports located in a steel structure. As shown in FIG. 1, horizontal disc saws 3 are attached to the first pair of supports, which are connected to the drive motors 1 through shafts 8 through special matrices 2. The second pair of supports have more vertical disk saws 5 attached and are connected to the drive ones. motors 4. The saw blades 5 are adjusted to the required section width by restraining rings 6. The horizontal saw blades 3 move to each other in such a way that they do not meet when cutting the timber 7.

Figure 2 shows the attachment of horizontal disc saws 3 to the special die 2 by means of a bolt 9. In turn, the die 2 is connected to the drive motor 1 through a shaft 8.

The operation of the device and the implementation of the method according to the invention are shown in FIG. 1 depicting the treated timber and the cutting operation.

The first cutting of the treated wood 7 is made by horizontal circular saws 3 simultaneously. In this way, the top layer is cut along its entire length. The mass thus treated is cut as required by horizontal 3 and vertical 5 circular saws. In cases where large-sized timber is cut and horizontal disc saws 3 cannot cut the whole layer at once, the saws 3 and 5 are used simultaneously on both sides of the timber 7, which allows the supports to move in the transverse direction. After cutting one layer from the table, the support carrier moves down to the required size and the whole procedure is repeated.

Attaching the horizontal circular saws 3 to the special die 2 through the bolt 9 allows the movement of the circular saws across the entire width of the workpiece 7, and the small circular saw blades 3 can cut large thickness wood.

In the case where vertical disc saws 5 of different diameter are used, the supports of the horizontal disc saws 3 are adjusted to the vertical saws 5 in a vertical direction so that a plane of cuts is obtained in both the vertical and horizontal positions. Horizontal circular saw blades 3 are selected so that they cut on the inside of the timber 7. This extends their service life. For these reasons, one die 2 is made with a right-hand thread and the other with a left-hand thread to prevent them from loosening. The horizontal disc blade 3 is inserted into the die 2 through a central hole in the disc and connected to it through rivets 9 along the circumference of the die.

Application of the invention

The method of longitudinal woodworking by cutting in two planes and the device for its implementation are mainly applicable in the woodworking industry, civil engineering and other areas for technically equivalent woodworking operations.
