Description

[Detailed Description of the Invention] The present invention relates to a edge fine adjustment device for a band saw machine.

Figure 1 shows the edge fine adjustment device for a conventional bandsaw machine.
3 is a sill, which is supported by the sill support body 2 and has a groove 15 formed therein to restrain its rotation, and is attached so as to be slidable in the direction of the arrow in FIG.

Reference numeral 13 is a fine-adjustment screw that is screwed into the crest 3 attached to the crest support 2, and is attached to the crest support 2 with a seat 16 screwed therebetween.

14 is a spring that eliminates play.

This conventional structure has disadvantages in that, in the case of a wide band saw blade, at least four pieces need to be attached on both sides of the band saw blade, and adjustment is complicated.

The present invention was developed in view of the above situation, and it is an object of the present invention to provide a device for finely adjusting the edge of a band saw machine, which can easily adjust even a wide band saw blade with a small number of blades.

The shear fine adjustment device for a bandsaw machine of the present invention has a recess formed in the middle part of the band saw blade, contact parts contacting each other at both ends, and a groove in the front and rear direction of the center position of the recess. A spring is attached to the sling attached to the sling, and the sling is screwed to the sling support via a loosening member by a spring attached to urge the sling in a direction away from the band saw blade, and the two contact portions are attached so as to be in contact with the band saw blade, respectively. 2
The fixing screw is fitted into the groove for fixing the edge finely adjusted by an iron thread member and screwed onto the edge support.

An embodiment of the edge fine adjustment device for a bandsaw machine of the present invention will be described below with reference to FIGS. 2 and 3.

Reference numeral 1 indicates a band saw blade, and 2 is fixed to the main body of the band saw machine using a support member.

3, the contact portions 16 and 16 have a concave portion 15 formed in the middle of the band saw blade 1 and contact the band saw blade 1 at both ends.
is provided at the center of the recess 15 in the front-rear direction (band saw blade 1
A groove 17 is formed in a direction perpendicular to the surface of the substrate.

Reference numeral 6 denotes a shear fixing member, which is fixed via a fixing screw 7 that is inserted into a groove 17 and screwed and fixed to the shear support 2; It has a locking piece 18 for locking, and on the other end side, the movement toward the bandsaw blade 1 is guided by a guide rod 8 which is screwed onto the edge support 2 and further fixed by a female fixing screw 10 to prevent loosening. It has become.

The edge 3 is attached between the edge support 2 and the edge fixing member 6 via a spring 9 that is biased in a direction in which the center portion moves away from the bandsaw blade 1.

Note that the guide rod 8 and fixing female screw 10 are for guiding the spring 9, and the fixing screw 7
This is to fix the

Further, a screw member 4 screwed onto the berth support 2 via a spring 5 serving as a locking member is in contact with the back surface of each of the left and right contact portions 16 of the berth 3.

In the case of fine adjustment of the edge 3, first loosen the fixing bolt and turn the screw member 4 so as to move it toward the band saw blade 1. The edge 3 is pushed by the screw member 4 and approaches the band saw blade 1.

Further, when the screw member 4 is turned in the opposite direction, the serpentine 3 and the serpentine fixing member 6 are moved in a direction away from the bandsaw blade 1 by the spring 9.

After finely adjusting the position of the contact portion 16.16 with respect to the band saw blade 1 in this way, the fixing screw 7 is fixed to the edge support 2.

Since the edge fine adjustment device of the band saw machine of this embodiment is configured as described above, it is possible to fix the edge after adjusting the contact device without comparing the contact parts on both sides of a wide bandsaw blade, and the operation can be performed easily. It's extremely easy.

Furthermore, even with a wide band saw blade, it is sufficient to attach one blade to each side, and the number of blades to be installed can be reduced.

As described above, the edge fine adjustment device for a bandsaw machine of the present embodiment has the effect that adjustment work is easy and the number of devices to be installed can be reduced.
