面を得ることができなという欠点があつた。 In order to perform high-precision processing of the surface of flexible materials such as honeycomb cores and foamed plastics, for example, when processing curved surfaces, a cutter for cutting flexible materials equipped with a sharp circular cutting blade is generally used in the processing machine. The cutting process is performed by attaching the machine to a machine and moving it while rotating at high speed. However, the fourth
As shown in the figure, conventional cutter A for cutting flexible materials
In general, a cutting blade holder D has a large-diameter cutting blade mounting portion C integrally formed at the tip of the shaft portion B, and a circular cutting piece with a diameter larger than the cutting blade mounting portion C is attached to the mounting surface of the cutting blade mounting portion C of the cutting blade holder D. Since the blade E is detachably provided, when cutting a large amount at one time, the cutting resistance is large and the cutting blade E is likely to seize, resulting in problems with durability.
It has the disadvantages of being prone to burrs and poor machining accuracy, so if there is a large amount of cutting, it is necessary to cut small amounts at a time, which means that machining takes a lot of time, resulting in poor work efficiency and high costs. There was a problem with that. In addition, depending on the material of the workpiece, chips continuously generated during cutting may wrap around the cutting blade holder D or the cutting blade E, and the machined surface may be damaged by the chips, making it difficult to perform high-precision processing. The drawback was that I couldn't get a face.

提案するを目的としたものである。 The present invention was developed in view of the above-mentioned circumstances, and a cutting blade holder having a large diameter cutting blade mounting part at the tip of the shaft part has a large diameter cutting blade mounting part on the front end mounting surface of the cutting blade mounting part. In a cutter for cutting flexible materials that is provided with a removably attached cutting blade, a desired number of cutters having a diameter larger than the cutting blade attachment part and less than or equal to the cutting blade are provided between the cutting blade attachment part and the cutting blade. By providing an auxiliary cutting section with a blade, the auxiliary cutting section further cuts the chips that come out from the workpiece into pulverized pieces and scatters them. When cutting, it reduces the cutting resistance applied to the cutting blade, and also eliminates the situation where chips get wrapped around the cutting blade depending on the material of the workpiece, thereby increasing the durability of the cutting blade. The purpose of this invention is to propose a cutter for cutting flexible materials that can improve processing accuracy and work efficiency.

Although the configuration in which the auxiliary cutting part 4 and the cutting blade 3 are attached to the cutting blade holder 2 has been described, the mounting structure of the auxiliary cutting part 4 and the cutting blade 3 is not limited to the embodiment, and for example,
Screw holes are formed at positions equally divided into an appropriate number on the desired circumference of the mounting surface 8, and each unit cutting blade 4a, 4a of the auxiliary cutting part 4, the cutting blade 3 and the holding plate 5a of the mounting member 5 are formed. A screw insertion hole is formed at a position corresponding to each of the screws in the holding plate 5a, and a countersunk seat is formed on the front surface of the screw insertion hole in the holding plate 5a, and a countersunk bolt is used to support the screw insertion hole between the two members 2 and 5. A configuration in which the cutting portion 4 and the cutting blade 3 are held between them may also be used.
In addition, the mounting surface 8 of the cutting blade holder 2, the mounting member 5
The structure of the pressure contact surface 10 is not limited to the embodiment, and the mounting surface 8 and the pressure contact surface 10 are each formed into a smooth surface, and the auxiliary cutting part 4 and the cutting blade 3 are formed into a flat plate without being elastically deformed. A configuration in which it is normally attached may also be used. In addition, in the case of such a configuration, it is of course necessary to attach the shaft portion 6 to the processing machine in a slightly inclined manner to perform cutting in order to prevent the outer end of the mounting member 5 from coming into contact with the processing surface. be. In addition, the cutting blade 3, the blade part 14 of the auxiliary cutting part 4,
15 is also not limited to a knife-like blade part, but may be provided with a saw-blade-like blade part, and even if the cutting blade 3 and the auxiliary cutting part 4 have the same diameter, or the auxiliary cutting part The diameter of each blade part of 4 is the mounting surface 8
The diameter may be formed gradually smaller toward the side. Furthermore, the structure of the auxiliary cutting part 4 is not limited to the embodiments, and may be integrally formed, and the number of blade parts 15 of the auxiliary cutting part 4, the mounting structure (for example, the mounting interval), etc. However, the present invention is not limited to the embodiment, and may be such that the auxiliary cutting section 4, which is made up of a single blade section 15, is attached with a slight spacing from the cutting blade 3.

ことはない。 Since the cutter 1 for cutting soft materials according to the present invention has the above-described configuration, the chips that are continuously cut by the cutting blade 3 are cut into pieces by the auxiliary cutting part 4 and scattered. Even when cutting a large amount at one time, large cutting resistance is not applied to the cutting blade. In addition, since the chips are cut into pulverized pieces and scattered by the auxiliary cutting section 4,
Chips will not wrap around the cutting blade 3 or the like and damage the machined surface.

Because the chips are scattered, even if a large amount of cutting is performed at one time, large cutting resistance is not applied to the cutting blade, and chips do not wrap around the cutting blade, etc., which improves the durability of the cutting blade and the machining process. Its effects are remarkable and significant, such as improving accuracy and making it possible to improve work efficiency, eliminating the drawbacks that conventional cutters for cutting soft materials of this type had. .
