Description

[Detailed Description of the Invention] The present invention relates to a ruler with a variable sawing angle for band saw table work.

Generally, table work with a bandsaw machine involves cutting pillar materials, i.e., square timbers or rectangular timbers, so that the two adjacent sides of the wood are at right angles, and the two adjacent sides (bottom and sides) are at right angles. A band saw machine is equipped with a table surface and a basic ruler.

However, the long presses and tile beams are made long and cut so that one end edge in the longitudinal direction has a different thickness than the other end edge, and one side surface is tapered.

As shown in Figure 4, these long presses and tile beams are formed by cutting a rectangular or square timber at a right angle into two halves at the required angle of inclination, but in table work it is not possible to cut the rectangular or square timber at this angle of inclination. Because it is difficult to make long presses, tile beams, and triangular materials, a tool that is angled according to the angle is placed on the table of the bandsaw machine to make the angle cuts along the basic ruler, as shown in Figure 5. The wood is aligned with the ingredients and sawed using a bandsaw to produce long pressed tile beams, triangular timbers, etc.

Therefore, in this process, the wood to be sawn is fed onto the table along the support tool, so the bottom of the wood is only partially supported, making it impossible to make accurate diagonal cuts. Visual work required skill.

In view of this, the present invention aims to easily perform accurate angle cutting (grinding angle) while reliably supporting the entire bottom and one side of the bottom of the material to be cut.

The present invention will be described below based on embodiments shown in the drawings.

In the figure, reference numeral 1 denotes the main body of a conventional band saw machine, and the main body 1 is provided with a basic ruler 3 that is adjustable with respect to the band saw 2.

The present invention is to provide a basic ruler that approaches or separates from the band saw along this table, and a ruler A with a variable sawing angle that can be detachably attached to the table.

The above-mentioned adjustable grinding angle ruler A has an L-shaped auxiliary ruler 6 pivotably attached to the base 4 via a shaft 5, the vertical piece and the bottom piece being connected at 90 degrees. At the same time, an angle adjustment device 7 is provided between the auxiliary ruler 6 and the base 4.

The base 4 is provided with a plurality of magnets 8 on the side opposite to the auxiliary ruler on the bottom surface so as to be attracted to the table or the surface of the basic ruler, and the attraction force of the magnets 8 is used to hold the base 4. The main body of the ruler with variable grinding angle is set at a predetermined position on the table.

At this time, adjust the distance to the side surface of the band saw by sliding the basic ruler and set it at a predetermined position.

Further, adjustment in the forward direction of the band saw is performed using a set bolt 9 provided on the base.

That is, the amount of protrusion is varied by rotating the set bolt 9, and adjustment is performed by bringing the end face of the set bolt into contact with a part of the basic ruler.

The angle adjustment device 7 for tilting the auxiliary ruler is an auxiliary ruler;
It consists of a bracket 7a protruding from the back side of the vertical piece, a screw rod 7C screwed onto the bracket 7b protruding from the base side, and a locking lug 7d screwed onto this screw rod. is pivotally attached to the bracket) 7a, and by rotating the handle H provided on a part of the threaded rod, the threaded rod is moved forward and backward, and after tilting the auxiliary ruler to a desired angle,
It is fixed with a lock nut.

When using the variable grinding angle ruler of the present invention constructed as described above, the material to be sawed can be held at the desired angle of inclination using the L-shaped auxiliary ruler, making it easier to grind the material. It has the advantage that processing can be performed accurately and the inclination angle can be easily adjusted as desired.
