Abstract

PURPOSE:To reduce the vibration of a back plate and the noise generated from the back plate by constituting the end part coming into contact with an endless cutter of the back plate of a guide member made of a damping material. CONSTITUTION:The back plate 50 supporting a part of an endless cutter C so as to press the same to a material to be cut is constituted by fixing elongated guide members 50B to the upper and lower end surfaces of a flat plate main body 50A. The material quality of the guide members 50B is constituted of a damping material such as a carbon fiber reinforced composite material or phosphor bronze and the friction resistance of the guide members 50B and the flaps of the cutter C is reduced and the chatter vibration of the back plate is reduced. Since the guide members 50B and the plate main body 50A are different in material quality, they are also different in resonance vibration frequency and vibration energy is absorbed at the bonding interfaces of both of them and the vibration of the back plate 50 is reduced to reduce noise.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting device for cutting various large-sized work materials such as stone, wood, metal, plastic, glass and ceramics.

[0002]

2. Description of the Related Art For cutting large-sized work materials of this type,
Conventionally, a cutting blade, a band saw, a wire saw and the like have been generally used.

The cutting blade is a large-diameter disk-shaped base metal with abrasive grain chips fixed to the outer periphery at equal intervals. Currently, up to 3.5 mφ and base metal thickness 10 mm are manufactured. ing. With this size, the maximum thickness of the work material that can be cut is about 1.5 m, and the cutting allowance is about 15 mm.

A band saw is made by endlessly welding a wide band-shaped thin metal plate having a thickness of about 1 to 6 mm and fixing abrasive grain layer chips to one side edge thereof at equal intervals. The axes are arranged parallel to each other. It is wound between a pair of cylindrical rotating bodies that are rotated at a high speed, and cuts a stone material or the like by either edge of the parallel portion between these rotating bodies.

The wire saw has a diameter of several mm to 10 m.
An endless type in which cylindrical diamond abrasive grain chips are coaxially fixed at equal intervals on a wire rope of about m, and it is wound directly on the work material and driven at a high speed by applying a certain tension by a driving device. Thus, the work material is cut.

However, when the cutting blade has a large diameter, the wall thickness of the base metal is inevitably increased due to the requirement for strength, and the thickness of the abrasive layer tip is accordingly increased. For this reason, the cutting margin is increased and the yield of the work material is deteriorated.
In addition, it is extremely difficult to manufacture a base metal having a diameter of more than 3.5 m, and the thickness of the work material that can be cut is limited. In addition, such a large cutting blade is extremely inconvenient for handling such as transportation and cutting. It also had the drawback that the noise at the time was terrible (sometimes reaching 100 dB or more).

Further, in the wire saw, since the diameter of the abrasive grain layer tip used is large, the cutting allowance is larger than that of the cutting blade and the band saw, and the wire saw itself has no effect of restricting the cutting direction. The flatness and surface roughness of the cut surface are inferior to those of the cutting means.

Further, the band saw has a small thickness of the base metal and a relatively small cutting margin of about 4 to 8 mm and a good yield, but is wound between a pair of large cylindrical rotating bodies. Since the rotating body is moved in the axial direction to perform cutting, the cutting device has to be large in size, a large installation space is required, and the vibration of the band saw causes considerable noise. It was

Therefore, the inventor of the present invention first disclosed in Japanese Patent Application No. 1-247.
No. 674 proposed a cutting device which has a large size of a workable material, a compact device size, and improved cutting accuracy.

In this device, a large number of flat plate-shaped flaps are connected endlessly to an end face of the cutter body on the outer peripheral side, and a large number of cutting blades are fixed at equal intervals, and the endless cutter. Multiple sprockets that support the cutter,
Arranged inside the endless cutter along the winding plane,
A back plate that presses and supports a part of the endless cutter toward the work material to be cut, a cutter drive mechanism that rotates the endless cutter and the sprocket, and at least one of the work material and the endless cutter is wound. And a notch mechanism for moving to the other side along the plane of rotation.

[0011]

By the way, when the present inventors prototyped a cutting device having the above-mentioned structure and cut a stone material, the vibration of the endless cutter is transmitted to the back plate, and this back plate is It was found to vibrate and produce noise. This noise level is about 87 to 92 dB, which is smaller than that of the above-mentioned cutting blade and band saw, but it is preferable to further reduce it in order to improve the working environment.

The present invention has been made in view of such circumstances, and it is an object of the present invention to reduce the noise from the back plate as much as possible in the cutting device using the endless cutter.

[0013]

A back plate that presses and supports the material, a cutter drive mechanism that rotates the endless cutter and the sprocket, and at least one of the work material and the endless cutter are moved to the other side along the winding plane. In a cutting device including a cutting mechanism, an end portion of the back plate that comes into contact with the endless cutter is configured by a guide member made of a vibration damping material.

The guide member may be made of one or more materials selected from carbon fiber reinforced composite materials, fluorocarbon polymers, phosphor bronze and cemented carbide.

[0015]

In the cutting device according to the first aspect of the present invention, a part of the endless cutter is run while being supported by the end of the back plate, and the cutting blade of the supported part is cut into the work material. Cut the work material. At that time, vibration occurs in each cutting blade due to cutting resistance, but since a guide member made of a damping material is fixed to the contact surface of the back plate with the endless cutter, the back plate is fixed by this guide member. Vibration and noise from the back plate are reduced. At the same time, if the guide member and the plate body are made of different materials, the resonance frequencies are different, so that an effect of absorbing vibration energy at the joint interface can also be obtained.

Next, the back plate 50, which is a main feature of the present invention, will be described. Back plate 50
As shown in FIG. 4, is a rectangular plate having a thickness similar to that of the flap 90, and the width in the vertical direction is equal to that of the parallel portion of the endless cutter C wound between the sprockets 40. It is substantially equal to the vertical separation distance, and its left-right width is slightly smaller than the horizontal separation distance of each sprocket 40.

In the back plate 50 of this embodiment, an elongated guide member 50B is fixed along each of the upper end surface and the lower end surface of a flat plate-shaped plate body 50A, and the endless cutter C of these guide members 50B is fixed. The guide groove 5 having a V-shaped cross section complementary to the guide protrusion 104A formed on the inner peripheral end surface of the flap 90

The flaps 90 are fitted so as not to separate in the thickness direction.

As the material of the guide member 50B, a carbon fiber reinforced composite material, a fluorocarbon polymer such as a trade name "Turqite"), phosphor bronze, cemented carbide or the like, or a combination of two or more of these materials is used. ing. Guide member 50B
If the material is a metal, the guide member 50B and the plate body 50A can be joined by brazing, plasma welding, electron beam welding or the like. In addition, whichever material is used, the guide member 50 can be made with various adhesives.
It is possible to bond B.

The shaking effect can be further improved.

Next, the structure for supporting the work material will be described. As shown in FIG. 1, the floor surface F between the columns 1
Is provided with a pair of rails 70 and 72 extending in the front-rear direction, and the upper end of one rail 72 is sharpened in a V shape. A truck 74 is placed on these rails 70, 72, and a plurality of pairs of wheels 76, 78 of the truck 74 are mounted on the rails 70, 72.

Next, the plate tensioning mechanism is operated to move the plate support 46 to the right to apply proper tension to the back plate 50. If the tension of the endless cutter C is insufficient, the shaft support 34 is moved to the right to adjust the tension. Then, the drive motor 64 is operated, and the endless cutter C
While traveling, the elevating motor 32 is operated to lower the endless cutter C at a desired cutting speed to continue cutting to the lower end of the work material.

At this time, since the guide members 50B made of damping material are fixed to the upper and lower ends of the back plate 50, the frictional resistance between the guide member 50B and the flap 90 is small, and the chatter caused by the frictional resistance is small. Vibration can be reduced. In addition, since the guide member 50B and the plate body 50A have different resonance frequencies if the materials are different from each other, an effect of absorbing vibration energy can be obtained at the joint interface. Therefore, compared with the case where the guide member 50B is not provided, the vibration of the back plate 50 is reduced, the noise from the back plate 50 is reduced, and the working environment can be improved.

Further, when the guide member 50B is made of cemented carbide, the specific gravity of the cemented carbide is much larger than that of the plate body 50A, and therefore the difference in resonance frequency between the plate body 50A and the guide member 50B. Is remarkable, and the effect of absorbing vibration energy becomes remarkable due to the difference.

FIG. 5 and subsequent figures show another embodiment of the present invention. In the example of FIG. 5, the guide protrusions 12 are attached to the guide member 50B.
This is an example in which the guide groove 122 is formed in the flap 90 while forming 0. With this configuration, the same effect as that of the above-described embodiment can be obtained.

In the example of FIG. 6, it is assumed that the guide protrusion 120 having a rectangular cross section with a relatively large protrusion amount is formed on the guide member 50B, while the flap 90 is formed by laminating three plate members 90A to 90C. By making the central plate member 90B shorter than the plate members 90A and 90B on both sides, the flap 9
It is characterized in that the guide groove 122 is formed at 0. According to this configuration, a large fitting depth between the flap 90 and the back plate 50 can be ensured, so that chatter vibration is less likely to occur than in the above embodiment. Further, since the flap 90 has a three-layer structure, the plate members 90A to 90C can be formed by a low-cost manufacturing method such as punching, and the effect of damping vibration at the joint interface of the plate members 90A to 90C can be obtained. ..

The example of FIG. 7 is an example in which a resin layer 124 is formed between the guide member 50B and the plate body 50A. In order to provide the resin layer 124, a resin film having a constant thickness may be sandwiched between the plate body 50A and the guide member 50B and bonded by thermocompression bonding or various adhesives. As described above, these may be epoxy-based adhesives. , A urethane adhesive, a chloroprene rubber adhesive, an acrylic adhesive or the like may be used for adhesion, and this adhesive may be used as the resin layer.

The example of FIG. 8 is characterized in that a groove 129 is formed on the end surface of the plate body 50A, and a guide member 128 having a shape complementary to the groove 129 is fixed in the groove 129. With this configuration, the fixing strength of the guide member 128 can be improved.

The embodiment shown in FIG. 9 has a back plate 50.
This is an example in which the vertical width of is reduced so that only the lower edge thereof engages with the lower inner peripheral edge of the endless cutter C. In this case, the guide member 50B may be fixed only to the lower end of the back plate 50. In this example, both ends of the back plate 50 in the horizontal direction are also extended in the horizontal direction to form a triangular projecting portion 130, and a guide groove 51 (or a guide ridge) is also formed at the lower end of the projecting portion 130. By forming the flap 9 up to the vicinity of the winding portion around the sprocket 40,
It is characterized in that the supported region of 0 is expanded. According to this configuration, there is an advantage that the flap 90 can be smoothly introduced from the back plate 50 to the sprocket 40 and from the sprocket 40 to the back plate 50.

In the example shown in FIG. 10, the back plate 50
And a large number of slits 140, 1 penetrating in the thickness direction.
42 is formed. Slits 140,1
Each of the reference numerals 42 has an arc shape, the slits 140 are arranged in two rows in the horizontal direction, and the slits 142 extend from the center of the lower end portion of the back plate 50 to diagonally upper and opposite sides.
It is arranged in a letter shape. Adjacent slits 140, 14
2 partially overlaps in the vertical direction as shown in FIG. 3, and the overlapping amount W of the slit 140 is 5 times the total length of the slit 140.
It is preferably about 30%.

According to this example, in addition to the vibration damping effect at the bonding interface of the back plate 50, since the slits 140 and 142 hinder the vibration transmission from the lower end of the back plate 50 to the upper side, the vibration of the back plate 50 and Noise can be further reduced. In addition, the slit 14
Since 2 are arranged in a V-shape, the vibration transmission to the central portion, which is apt to vibrate, shown in (a) in FIG. 10 is effectively reduced, while the (b) portion supports the endless cutter C. The strength can be secured. The shape and arrangement of the slits may be changed as needed.

As another embodiment of the apparatus, although not shown, a plurality of guide grooves 42 are formed on the outer peripheral surface of the sprocket 40, and the endless cutter C is wound around each of the guide grooves 42, while the endless cutter C is wound. The same number of back plates 50 are provided for each of the blade-shaped cutters C.
The endless cutters C may be supported by.
According to this structure, a plurality of plate materials can be cut out at one time, so that the cutting efficiency can be significantly improved.

Furthermore, the endless cutter C used in the cutting apparatus of the present invention is not limited to the one shown in FIG. 3, and the endless cutter C shown in FIGS. 12 to 17 can also be used.
