Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a blade for a multi-blade cutting machine, and more particularly to a band used for cutting and grooving hard and brittle materials such as inorganic materials, such as slicing or dicing. This invention relates to a blade for a multi-blade cutting machine that can be securely fixed and is easy to assemble.

Conventionally, this type of blade has been used in which a large number of metal bands are arranged in parallel at both ends of the metal bands at a constant interval through spacers, and are crimped and fixed from the outside.

In this case, since the material to be cut is hard and brittle, the bands must be reliably held at regular intervals and parallel to each other.

Conventional methods of crimping and fixing the above bands include fixing the side surfaces of both ends of the band and the spacer with adhesive, or inserting a pin between multiple laminated bands and the spacer, and inserting a nut etc. from both ends of the pin. A tightening method is used.

However, among the above-mentioned pressure bonding methods, the method using an adhesive is time-consuming and there is also a risk that the bonded area may separate during blade setting and the blade may disintegrate.

In addition, with the method of tightening with pins, the surface area of the end of the band is small, so the band may collapse inside the spacer cabinet while setting the blade, or the spacer may tilt in a V-shape, leaving a space underneath and causing the band to move. Otherwise, dirt or the like may enter between the band surface and the spacer and the parallel spacing of the bands may become distorted, making it difficult to perform accurate cutting operations.

In order to solve the above-mentioned problems, ears are bulged at both ends of the band to increase its surface area, making it difficult for the band ends to collapse or move inside the stacked spacer cabinet. Alternatively, a U-shaped auxiliary spacer that has the same thickness as the band and surrounds the end of the band is interposed between the spacers so as to surround the end of the band together with the band. There are multi-blade cutter blades that are designed to prevent them from folding or moving within the spacer cabinet, but those with ears at the end of the band are made using a special method that allows the band to be integrally molded. This method requires a mold, a special large press, etc., and has the disadvantage of increasing equipment costs.

Further, in the case where a U-shaped auxiliary spacer is interposed between the spacers together with the band, there is a problem in that it takes time to assemble the blade, and the auxiliary spacer and the band may overlap or fall off.

Particularly recently, in order to improve cutting work efficiency, there has been a demand for blades for large multi-blade cutting machines that can cut many materials at once, and for this purpose, the bands that make up the blades have become tighter. Longer ones are now being used.

As a result, when assembling the cutting machine blade by alternately stacking bands and spacers, it is difficult for both ends of the long band to be seen at the same time by an assembling worker, making the assembling work extremely difficult.

SUMMARY OF THE INVENTION In order to solve the above-mentioned difficulties, it is an object of the present invention to provide a device that can securely fix a plurality of bands between spacers, has assembly holes at both ends, and is easy to assemble even if the band is long. multiple metal bands with perforations, a spacer wider than the band to maintain a certain distance between the bands, and a U-shaped auxiliary to fill in the space between the spacers other than the space closed by the band. Consisting of a spacer,
A notch is provided on the outer edge of the spacer located on the center line connecting the band assembly holes to lock the pin when the pin is inserted into the band, and the auxiliary spacer has a U-shaped vertical side. When the spacers are sandwiched between the spacers so as to protrude outside the spacer, insert holes for inserting pins between the spacer and the auxiliary spacer on both horizontal sides protruding from both ends of the vertical sides of the auxiliary spacer. At least one hole is drilled in each spacer, and an insertion hole is also drilled in the corresponding position of the spacer, so that when the band is moved horizontally by sandwiching the band between the spacers, the end of the band A blade of a multi-blade cutting machine, characterized in that the blade of the auxiliary spacer is appropriately bent near the vertical side of the auxiliary spacer to avoid the path of the band so that it can pass through the vertical side of the auxiliary spacer distilled from the spacer, and
A pair of laminated bodies are formed by stacking a plurality of spacers and auxiliary spacers alternately and a pin is inserted into the insertion hole of each spacer and auxiliary spacer, and these integrated laminated bodies are arranged in parallel at a predetermined interval. Then, between the stacked bodies, the band is inserted and held one by one in each spacer cabinet of the stacked body, and the auxiliary spacer is interposed between each spacer of the stacked body so as to straddle the band, and the bottom part of the auxiliary spacer is A plurality of band ends protrude from the outer edge of the laminate within a space surrounded by the auxiliary spacer that extends from the outer edge of the spacer by passing through the band so that the end of the band protrudes from the bottom of the auxiliary spacer. The ends of the bands are aligned by communicating pins with the assembly holes of the above band, and the gap between the pair of laminates is widened so that the side of the pin communicating with the assembly holes of the above band is aligned with the outer edge of each spacer of the laminate. After positioning the laminate with respect to the band by abutting against and locking the notch, the laminate is tightened from both ends of the pin communicating the laminate, and the band is crimped and clamped at a predetermined position within each spacer cabinet. The present invention provides a method for assembling blades of a multi-blade cutting machine.

Embodiments of the present invention will be described in detail below based on the drawings.

A band 10 is formed by cutting a metal ribbon into an appropriate length.

Assembly holes 12a and 12b are bored in the center of both ends of the band 10, respectively.

A spacer 14 is inserted at both ends between each band 10 in order to maintain a constant distance between adjacent bands 10 when a plurality of bands 10 are arranged in parallel.

Semicircular notches 16a and 16b for assembly are provided in the center of the outer edge of each spacer 14, respectively.

Reference numeral 18 denotes an auxiliary spacer for filling the space other than the space closed by the band 10 between the spacers 14, and the band 1
It is made of steel plate material with the same thickness as 0, and its overall shape is U-shaped.

Tightening holes 22a and 22b are bored in the middle of both horizontal sides 20a and 20b of the auxiliary spacer 18.

In addition, through holes 24a and 24b are formed in the upper and lower parts of the surface of the spacer 14 in such a manner that the horizontal sides 20a and 20b of the auxiliary spacer 18 are tightened in correspondence with the positions of the holes 22a and 22b.

The middle portions of both horizontal sides 20a and 20b leading to the vertical sides 26 of the U-shaped auxiliary spacer 18 are bent in a step-like manner with a step 28. The plane including the vertical side 26 of the auxiliary spacer 18 is formed so that it does not coincide with the plane including the vertical sides 26 of the auxiliary spacer 18 with respect to the plane including the spacers 20a and 20b, and the band is held horizontally by sandwiching the band 10 between the spacers 14. The end portion of the band 10 is configured to pass through the vertical side portion 26 of the auxiliary spacer 18 when moved in the direction.

Next, the blades of the multi-blade cutting machine according to the present invention are attached to the band 10, spacer 14 and auxiliary spacer 1 having the above-described structure.
An assembly method in which the pins 30a and 30b are laminated and pressure-bonded using the pins 30a and 30b will be described.

First, after inserting a pair of rod-shaped pins 30a and 30b into the through holes 24a and 24b on the surface of the spacer 14, tightening both horizontal sides 20a and 20b of the auxiliary spacer 18 is performed by inserting them into the holes 24a and 24b. The process is repeated, and the spacers 14 and auxiliary spacers 18 are alternately stacked along the pair of pins 30a and 30b.
Bolts or the like are screwed onto both ends of 0a and 30b, and a pair of temporarily tightened laminates 31 are assembled.

Next, one band 10 is inserted and held between each spacer 14 of the laminate 31 between the pair of laminates 31 to form a rectangular block.

In this case, the direction in which the band 10 is inserted between the spacers 14 is such that it passes through the vertical sides 26 of the auxiliary spacer 18 from the outer edge direction of the laminate 31, so that the band 10 is inserted between both horizontal sides 20a and 20b of the auxiliary spacer 18. or vice versa, both horizontal sides 2 of the auxiliary spacer 18.
The band 10 is inserted between the stacked spacers 14 so as to pass through the vertical sides 26 of the auxiliary spacer 18 from the tips of 0a and 20b in the direction of the vertical sides 26.

Also, in this case, the auxiliary spacer 18 between the spacers 14
is from the outer edge of the spacer 14 to its both horizontal sides 20
A, 20b and a portion of the vertical side 26 are formed to an appropriate size and stacked on each other so that the vertical side 26 can be removed. It is configured so that it is not crushed by the spacer 14.

Next, the plurality of bands 10 inserted between the stacked spacers 14 are aligned and positioned at fixed positions with respect to the spacers 14.

In this case, the band 10 is aligned by pressing a flat plate from both ends of the band 10.

In addition, in order to align a plurality of bands 10 to the stacked spacer 14 and position them in a fixed position, after aligning the ends of the bands 10 as described above, align the plurality of bands 10 arranged in parallel. The pin 32 is connected to the assembly holes 12a and 12b at both ends in a space surrounded by the auxiliary spacer 18 extracted from the spacer 14, and after temporarily tightening the pin 32 by inserting a bolt or the like into both ends of the pin 32, The entire band 10 inserted through the band 10 is moved relative to the laminated spacers 14, and the pins 32 inserted through both ends of the band 10 are pressed against the assembly notches 16a or 16b at the end edge of each of the laminated spacers 14. and position the band 10.

After the band 10 is positioned, it is then passed through the laminated spacer 14, and both ends of the pins 30a and 30b, whose ends are loosely tightened temporarily, are strongly tightened with bolts or the like.

Thereafter, the pins 32 for positioning passed through both ends of the band 10 are removed, and the assembly of the blades of the multi-blade cutter is completed.

In addition, in order to securely fix the band 10 with the laminated spacer 14, the positioning pin 32 is attached to the band 10.
It is also possible to leave it inserted without removing it from both ends.

Further, the positioning notches 16a and 16b provided at the ends of each spacer 14 may be formed into a V-shape, a box-shape, or the like instead of a semicircular shape.

Furthermore, the cutouts 16a and 16b are provided at both end edges of each spacer 14 so that the shape of the spacer 14 is symmetrical, and when stacking spacers 14, the directionality is checked each time. This is to eliminate the need for the cutout, and depending on the case, the notch may be provided only at one end edge of the spacer 14.

As described above, according to the blade of the multi-edge cutting blade according to the present invention, the plurality of bands constituting the blade are securely fixed with the auxiliary spacer interposed between the laminated spacers, so that the blade There is no risk that the band will bend or move within the spacer cabinet during setting, and the band will not hit perpendicularly to the material to be cut, resulting in a loss of cutting accuracy, making it possible to always perform accurate cutting. Become.

In addition, as mentioned above, the assembly method does not require stacking multiple bands while checking the positions of both ends at the same time as in the conventional method, and it is extremely easy to stack, position, and assemble the spacer and auxiliary spacer. In particular, the blades of a multi-blade cutting machine using a long band, which is difficult to check both ends at the same time, can be easily and quickly assembled. .

In particular, when assembling blades with the same cutting pitch, you can pull out the used band without disassembling and reassembling each component like with conventional blades. It can be quickly and easily used repeatedly by simply washing off the grinding fluid etc. with an ultrasonic cleaner or the like while the block is still tightened and replacing the band.

Although the present invention has been variously explained above with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.
