Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting table for forming a negative corner warp of a roof of a temple or shrine, and a curved plane used for the corner warp negative cutting table.

[0002]

2. Description of the Related Art Conventionally, in order to form a corner warp, it is necessary to rely on the intuition of a worker for a long time, or to draw a line on the side of the material that matches the warp and use a curved plane along the line. I was cutting. 【】

Corner warping Kayagi is especially seen on the roofs of temples and shrines, etc. When forming Kakuwari Kayagi, it is as described above, but even if it relies on the intuition of the operator for many years. When Kayagi is superposed in several stages such as two or three stages, it becomes impossible unless the warp conditions are the same, and only an expert can work.

Further, even in the case of cutting along the line drawn on the side surface of the material, it took skill to make the cutting surface horizontal.

In view of the above points, the present invention is to provide a cutting table capable of easily forming an accurate corner warp and a curved plane used for forming the corner warp. .

[0006]

In order to solve the above-mentioned problems, the corner warping and bending cutting table of the present invention has a horizontal portion formed at the center of the upper surfaces of both side plates connected at a constant interval, and the horizontal portion is formed in the horizontal portion. It is connected to form a bent portion that is bent upward on one side, and is connected to a horizontal portion, and a bent portion that is bent downward and has the same shape as the bent portion is formed on the other side. It is characterized in that a material mounting table having an upper surface of the same shape as that of the curved portion and the bent portion which is bent downward is provided so as to be slidable in the front-back direction and in the vertical direction.

The curved plane of the present invention is characterized in that bottom plates are provided on both sides of the cutting blade at the bottom of the main body.

[0008]

The operation of the corner warping and negative cutting table and the curved plane of the present invention will be described. A material cut to a length in which the horizontal portion of the upper surface of the side plate and one of the bent portions connected to the horizontal portion are cut together is cut. The material is placed near the bent portion of the table, which is bent upward, and is fixed by pressing the fixing tool from the side surface. The material mounting table is composed of a horizontal portion and a bent portion that is bent downward, and since there is no bent portion that is bent upward, it is placed in a horizontal state on the material mounting table.

Then, the upper surface of the material is cut with a curved plane along the shapes of the bent portion and the horizontal portion which are curved upward of the side plate. Since the bottom plate is provided on both sides of the cutting blade of the curved plane for cutting, when cutting to a certain thickness, the bottom plate contacts the upper surface of the side plate, and the cutting work can be performed as a guide. Therefore, the upper surface of the material has the same shape as the bent portion and the horizontal portion that are warped upward of the side plate, and is not overcut, and the cut surface is also formed horizontally.

Next, the material is once removed from the cutting table, the material is turned over and cut, and the upwardly curved bent portion is moved toward the downwardly curved bent portion side of the material mounting table to fix the material on the material mounting table. For example, the cut material surface matches the shape of the upper surface of the material mounting table. Then, when the material is cut along the shape of the bent portion which is curved downward of the side plate with the curved plane, the front and back sides of the bent portion have the same curved shape. Although the above is the method for forming the corner warp and the negative arm, the thickness of the corner warp and the negative arm can be adjusted by moving the material platform up and down. Further, by moving the material mounting table back and forth, it is possible to change the thickness of the warp of the bent portion, so that it is possible to cope with the size as designed.

In the figure, reference numeral 1 denotes a pair of left and right long side plates. A horizontal portion 1A is formed at the center of the upper surface of the side plate 1, and a bent portion which is connected to the horizontal portion 1A and is curved upward in one direction. 1B is formed, and a bent portion 1C that is connected to the horizontal portion 1A and has the same shape as the bent portion 1B and is bent downward is formed on the other side. The side plates 1 are connected at regular intervals by connecting bolts 2 and nuts 3 provided at the front and rear of the side plate 1 and connecting rods 4 provided at the bottom.

Reference numeral 5 denotes a material placing table provided between the side plates 1 and 1, and the upper surface of the material placing table 5 is formed in the same shape as the horizontal portion 1A of the side plate 1 and the bent portion 1C bent downward. . or,
Two front and rear screw cylinders 6 are embedded in the lower surface of the material mounting table 5, and a long hole 8 formed in the screw cylinder 6 in the front-back direction of a support plate 7 provided between the side plates 1 and 1 below the screw cylinder 6. The spiral rod 9 is screwed in more. Therefore, the material mounting table can be adjusted up and down by turning the handle 10 of the spiral rod 9. Then, when the material mounting table 5 rises and a gap is formed between the material mounting base 5 and the support plate 7, several kinds of spacers (not shown) having different thicknesses are interposed in the gap.
Further, by loosening the screw rod 9 of the material mounting table 5, the screw rod 9 can slide in the elongated hole 8 and thus slide in the front-back direction.

A fixing tool 11 comprises a screw rod 15 which is screwed into the nut 12 embedded in the side plate 1 from the outside of one side plate 1 and which has a pressing piece 14 for pressing the side portion of the wooden material 13 at its tip. . Reference numeral 16 is a handle of the spiral rod 15. The fixtures 11 are located near both ends of the horizontal portion 1A of the side plate 1 and the bent portions 1B and 1C.
Are provided at four locations in the approximate center.

Reference numeral 17 denotes a curved plane main body, 18 a cutting blade, and 19 a bottom plate attached to the bottom of the curved plane main body 17, which extends on both sides of the cutting blade 18. Reference numeral 20 is an arcuate bottom plate provided on the front bottom of the curved plane main body 17.

Reference numeral 21 in the figure denotes a roof portion provided with a corner warp kaya negative 22.

[0016]

According to the present invention, the material placed on the material mounting table of the cutting table is cut along the upper surface of the side plate, and since the bottom plates are present on both sides of the cutting blade of the curved plane, Since the bottom plate abuts on the side plate, overcutting does not occur, and the cutting surface becomes horizontal without tilting, and accurate cutting work can be easily performed by not only the expert but also the beginner.
Further, it is a useful invention that the thickness of the bending of the bending and the thickness of the bending of the bent portion can be changed, and the bending of the bending of the corner can be accurately formed according to the dimension.
