種類ある。2. Description of the Related Art Conventional horizontal band saws are roughly divided into two.
There are types.

あり、価格も安い。[0003] One is a horizontal band saw that cuts a cutting material by swinging a band saw in a frame up and down around a hinge shaft as a rotation fulcrum. When the base was integral and the frame was at the lower limit position, the height of the band where the cutting edge travel line of the band was parallel to the upper surface of the base was always constant. In addition, this method is very common as a horizontal band sawing machine, and is inexpensive.

This is because when the frame is at the lower limit position, the angle between the cutting edge travel line of the belt and the upper surface of the base can be set to a desired angle, and the height of the belt where the travel line of the belt and the upper surface of the base are parallel is free. Can be set to However, because of its structural complexity, it is expensive as a horizontal band saw.

く取れる為、切込みが大きくなる）。Conventional horizontal band saws can be roughly classified into two types. A horizontal band saw in which a band saw in a frame moves up and down to cut a cutting material is a frame saw. When is at the lower limit position, the angle between the cutting line of the band and the upper surface of the base can be set to a desired angle. Therefore, the cutting line and the base of the band are optimal for various materials (flat bars, square pipes, etc.). The angle of the upper surface can be set, so that the actual cutting length can be shortened, breakage of the band saw blade due to clogging can be prevented, and the cutting time can be shortened. .

フレームを支持する支柱の剛性を強くする必要があり、
大掛かりな横形帯のこ盤となってしまい、価格も非常に
高くなってしまう。In addition, since the lower running line of the belt and the upper surface of the base can be made parallel to each other, a groove can be formed in the cutting material parallel to the upper surface of the base. However, due to its structural complexity,
It is necessary to increase the rigidity of the column supporting the frame,
The result is a large horizontal band saw, and the price is very high.

しまう。The other is a horizontal band sawing machine for cutting a cutting material by swinging a band saw in a frame up and down around a hinge shaft as a rotation fulcrum. The height of the lower limit position of the frame whose upper surfaces are parallel is fixed and the price is low. However, when grooving the above cutting material parallel to the base upper surface,
Fixing jigs and the like for the cutting material in consideration of the depth of the groove and the angle between the lower running line of the band at that time and the upper surface of the base are required.

小さくなってしまう。Further, a horizontal band sawing machine which is fixed so that the cutting line of the band and the upper surface of the base are substantially parallel to each other near the cutting end of the cutting material is particularly suitable for cutting flat bars and square pipes. At the time, when the band saw comes near the cutting end of the cutting material, the actual cutting length becomes longer, so the cutting time becomes longer (the cutting load becomes smaller because the cutting load of one blade becomes smaller). The cutting power of the swarf became poor, causing the band saw to break due to clogging of the band saw blade.
In addition, the horizontal band sawing machine that has an angle between the cutting line of the band and the upper surface of the base near the end of cutting of the cutting material can prevent breakage due to clogging of the band saw blade, and the cutting time is short. However, because of the endless band, the distance between the base surface and the opposite band that is being cut is smaller than that of the horizontal band sawing machine where the cutting edge travel line of the band and the upper surface of the base are almost parallel. As a result, the height of the material that can be cut is reduced.

挾持案内されている。In FIG. 1, a frame 1 swings up and down around a hinge shaft 4 supported by a hinge 3 provided at a right end of a base 2 on which a cutting material 10 is placed. A saw wheel 5 and a saw wheel 6 are rotatably arranged on the left and right sides of the frame 1, and a band saw 7 is stretched between the saw wheels 5 and 6. When the driving saw wheel 5 is driven to rotate by a driving motor (not shown), the band saw 7 circulates between the saw wheels 5 and 6. The band saw 7 partially exposed from the frame 1 is guided by a pair of heads 8 and 9 disposed on the frame 1 so as to be twisted at right angles to the upper surface of the base 2.

The cutting material 10 is clamped and fixed between the fixed vice 11 and the moving vise 12, and is cut by the band saw 7 by swinging the frame 1 downward.

る。The hinge 3 is fixed to the base 2 by inserting a fixing member 13 such as a bolt through an elongated hole 3a provided in the hinge 3 and screwing it into a screw hole (not shown) provided in the base 2. The hinge 3 is slidable in the vertical direction by a concave and convex groove (not shown) provided on the contact surface between the hinge 3 and the base 2 in the vertical direction, and is restricted from moving in the horizontal direction.

When setting the height of the band saw 7 in which the upper surface 2a of the base 2 is parallel to the base 2, the fixing member 13 is loosened, the hinge 3 is moved upward or downward, and the fixing member 13 is tightened. The frame 1 and the band saw 7 are on the upper surface 2a of the base 2.

る。According to this embodiment, the height of the band saw 7 at which the cutting edge travel line 7a of the band saw 7 is parallel to the upper surface 2a of the base 2 can be set by moving the hinge 3 in the vertical direction. When grooving the cutting material 10, as shown in FIG. 3, the height of the band saw 7 in which the cutting edge travel line 7 a of the band saw 7 is parallel to the upper surface 2 a of the base 2 depends on the groove processing depth. Thus, the cutting edge travel line 7a of the band saw 7 can be higher than the upper surface 2a of the base 2. In the case of cutting a flat bar, a square pipe, or the like, as shown in FIG. 4, the height of the band saw 7 where the cutting edge travel line 7a of the band saw 7 is parallel to the upper surface 2a of the base 2 is determined. By making it lower than the upper surface 2a, an angle θ is formed between the cutting edge traveling line 7a of the band saw 7 near the end of cutting of the cutting material 13 and the upper surface 2a of the base 2.
The actual cutting L of the cutting material 10 can be shortened, and the number of blades of the band saw 7 in the actual cutting L can be reduced. As a result, the cutting load of one blade is increased, and the cutting depth is increased, so that the cutting speed can be increased.

大きくできるため、切断スピードも速くなる。According to the present invention, by providing a fixing member that allows the hinge to move in the vertical direction and to fix the hinge at a desired position, the cutting edge traveling line of the band when the frame is at the lower limit position and the base are moved. Since the height of the lower limit position of the frame whose upper surface is parallel can be set, the material can be grooved according to the grooving depth of the material without using a jig or the like for slanting the material. If the height of the band where the cutting edge travel line of the band and the upper surface of the base are parallel to each other is set to a position lower than the base, the band near the end of cutting of the cutting material has an angle on the upper surface of the base. Material dimensions /
Due to differences in shape (especially flat bars, square pipes, etc.)
The actual cutting length (the length at which the cutting material is actually cut) is shortened, so that the load at the time of cutting can be reduced, and clogging of the band saw blade can be prevented. Further, the number of the blades in the band which is actually cutting the material can be reduced, and the cutting load per blade can be increased, so that the cutting speed can be increased.
