[Problems to be Solved by the Invention] However, unlike interlocking tiles and tiles for pavement, unlike tiles and the like, it is difficult to cut them, and it takes a lot of time if the amount is large, and extra manpower is required. There was a problem of becoming. In addition, since the hand-held tool has a limited cutting width, there is a problem in that the cut surfaces may be uneven and the degree of finish may be reduced. In this case, it is possible to use an electric cutter, but it is difficult to prepare and transport the power supply, and extra caution and monitoring such as danger due to high speed rotation, dust countermeasures, noise countermeasures are necessary, In addition, there may be a problem that skilled workers are required.

The present invention has been made to solve the above conventional problems, and its purpose is to:
Interlocking, roof tile, etc. can be cut linearly at any position in a short time, and it is safe, does not generate dust or noise, is easy to operate, and can be easily used by anyone. It is to provide a hydraulic cutter that can be used.

[0005]

As means for achieving the above object, in a hydraulic cutter of the present invention, a machine frame having a pair of lifting guides; a horizontal top fixed horizontally across the upper and lower guides. A member; an upper lower blade facing the horizontal upper member and held up and down by an elevating guide; an elastic body fixed to both sides of the lower blade, and a pair of horizontal members above the elastic body on both sides of the lower blade A movable table fixed to the elastic body in a state where the material is arranged and the upper surface of the horizontal material is appropriately held above the lower blade; and a jack fixed to the machine frame to move the lower blade up and down. It was a prepared structure.

[0006]

In the hydraulic cutter of the present invention, since the lower blade is provided with the movable table, the movable table has an interface.
Place blocks such as rocking. At this time, since the lower blade is separated from the lower surface of the block, the block can be positioned in a stable state. When the jack-up is performed after the positioning is completed, the upper surface of the block comes into contact with the horizontal upper member and the elastic body bends so that the lower blade also comes into contact with the lower surface of the block. When further jacked up, the block is subjected to shearing force by the lower blade and cut into a straight line as the lower blade.

Since the next work can be performed immediately by just jacking down, the work can be efficiently advanced in a short time. In addition, the cutting surface is cut linearly by the lower blade, and the finish of the construction site can be neatly and neatly arranged. Further, since only static shearing force acts on the block, no dust or noise is generated and safe work can be performed.
Further, since the work is performed only by positioning and operating the jack, anyone can easily use it and always obtain a processed product of good quality.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a vertical sectional view showing a hydraulic cutter of this embodiment, FIG. 2 is a front view of the same, and FIG. 3 is a process diagram showing the usage state of the same in the order of (a), (b) and (c). is there. The hydraulic cutter A of this embodiment mainly includes a machine frame 1, an upper blade 2, a lower blade 3, a movable table 4, and a hydraulic jack 5.

The machine frame 1 mounts the upper blade 2, the lower blade 3 and the hydraulic jack 5 and forms an elevating guide 10 for the lower blade 3. In the embodiment, two angle members 11 are used. It is formed by vertically arranging the flanges 12 aligned in the same direction on the left and right of the base 13. The angle members 11, 11 have flange portions 12, 1 on both sides.
The two are fixed while holding a gap 14, and this gap 14 serves as a hoistway 15 for the lower blade 3. Reference numeral 16 in the drawing forms a lateral beam of the base 13, and the lateral beam 16 is fixed by being sandwiched between the angle members 11, 11.

The upper blade 2 is a horizontal upper member for cutting the upper surface 60 side of the block 6, is formed to have substantially the same thickness as the horizontal beam 16, and is the upper end of the elevating guide 10. Is inserted between the hoistways 15, 15 with the blade facing downward, and is firmly fixed to the angle members 11, 11 by bolts 20.

The lower blade 3 is for cutting the lower surface 61 side of the block 6, is formed to have a thickness slightly smaller than that of the hoistway 15, and both ends 30, 30 have both hoistways 15, 1.
It is inserted in 5 so that it can move up and down.

The movable table 4 is for mounting a block 6 to be cut, and horizontal brackets 31 and 31 are projectingly provided on both sides of the lower blade 3 below the central portion thereof, and the upper surfaces of the horizontal brackets 31 and 31 are projected. Two column-shaped elastic rubbers 40 are arranged as elastic bodies. A pair of upper plates 42 as horizontal members are arranged on the upper surface of the upper blade 42 while holding a gap 41 of approximately the thickness of the lower blade 3, and a bolt 43 protruding from the lower surface of the upper plate 42 is provided. The movable table 4 having a structure in which the upper surface plate 42 is held by the elastic rubber 40 is provided by fixing the elastic rubber 40 in the penetrating state to the horizontal bracket 31. The elastic rubber 40 is formed to have a hardness and a height such that the lower blade 3 does not protrude from the upper surface plate 42 when the block 6 is placed on the movable table 4. In the figure, reference numeral 44 denotes a holding ring provided on the lower surface side of the upper surface plate 42, and the elastic rubber 40 is capped from above. Further, 42 a is the upper surface of the upper surface plate 42.

The hydraulic jack 5 is for moving the lower blade 3 up and down to cut the block 6, and a manual type is fixed to the cross beam 16 at the center position of the lower blade 3, and the piston of the hydraulic jack 5 is fixed. The rod tip 50 is formed so as to contact the lower surface of the lower blade 3. Further, in the embodiment, the spring 51 is locked to the horizontal beam 16 of the base and the horizontal bracket 31 of the lower blade in a tensioned state so that the speed of the hydraulic jack 5 at the time of lowering is increased. In the figure, 52 is a lever that is detachably attached to the hydraulic jack 5,
Reference numeral 53 is an insertion ring that is stored when the lever 52 is not used.

Next, the operation of the embodiment will be described with reference to FIGS. First, the block 6 is placed on the movable table 4 in a jacked down state (FIG. 3A).
In this case, the block 6 need not be positioned, but it is placed so that the marking line of the block 6 is on the upper surface side. After placing the block 6 on the movable table 4, the lever 52 is operated to jack up (FIG. 3).
(B)). Moreover, the upper blade 2 and the block 6 are positioned so that the marking lines of the block 6 coincide with each other immediately before the upper surface 60 of the block 6 contacts the upper blade 2. When the block 6 is positioned and jacked up again, the upper blade 2 presses the upper surface of the block 6 to press the upper plate 42 of the movable table 4 downward, and the upper plate 42 compresses the elastic rubber 40. .
When the elastic rubber 40 contracts, the lower blade 3 projects from the gap 41 between the upper surface plates 42 and contacts the lower surface 61 of the block 6. At this time, the block 6 has the upper blade 2 at the same position on the upper and lower surfaces.
And the lower blade 3 receives a shearing force and instantly cuts (Fig. 3
(C)).

As described above, according to this embodiment, after the block 6 is placed on the movable table 4 and positioned, the block 6 can be cut along the marking line simply by operating the lever. This positioning can be easily performed by anyone since only the marking line is aligned with the upper blade 2, and the cutting surface can always be straight and can be machined so as to obtain the same quality. In addition, block 6
Since it does not require extra time for fixing with a vise or the like, it can be processed in a short time. Further, since there is no rotating part, it is safe, and therefore noise and dust are not generated. Further, since all the cut blocks 6 remain in a state of being placed on the movable table 4, they can be taken out easily.
