のである。 Regarding the manufacturing technology of short metal fibers, a special patent application was filed in 1974.
161911, the short metal fibers produced by this technique are as shown in Fig. 1.
When the short metal fibers have a length of 10 mm or less and a cross-sectional diameter of 100 μm or less, the short metal fibers 1 have a sharp shape at both ends as shown in 1a and 1b. When handling such short metal fibers, there is a risk that the ends of the short metal fibers may touch the skin of the worker during each work process, such as cleaning, inspection, packaging, and mixing with other materials. However, in order to solve this problem, the present invention relates to a short metal fiber tool that uses a special cutter to manufacture short metal fibers without sharp parts. be.

維に於ても端面角形状のものが製造される。 The following will be explained based on examples. Fig. 1 shows short metal fibers manufactured by a conventional method. Cutting is performed by applying self-excited vibration to a special elastic tool, resulting in less dimensional variation. Short metal fibers are made, but since the short metal fibers produced by this self-excited vibration method are given self-excited vibrations, the cross-sectional shape of the short metal fibers that are scraped off generally has a non-circular cross-sectional shape. ing. In this case, in the process of cutting short metal fibers with a metal block, the special elastic tool is slightly bent in the rotational direction of the metal block, and when the special tool returns to its original shape after cutting a certain amount of short metal fibers, the final During cutting, the short metal fibers are stripped off, resulting in sharp edges as shown in FIG. 2A. In addition, 3, 4, 5 are short metal fibers, 6 is a knife, 8, 8', 8'' are cutting edges of the knife, 9 is a metal block, and the direction of arrow B is the cutting direction.
The figure shows an improvement to this, in which short metal fibers 2 are made into rectangular shaped short metal fibers in which both ends 2a and 2b are not sharp, as shown in FIG. 1 and 2.
13 is a knife, 15, 15', 15'' are cutting blades of the knife, 10, 11, 12 are short metal fibers, 1
9 is a metal block, and 17 and 18 are grooves cut into the metal block using a grooving knife. FIG. 4 shows a concrete structure, where 20 is a blade for cutting grooves on the metal block 40, 21, 22, and 23 are cutting blades, and 24 is a hole for fixing the blade. 30 is a short metal fiber cutting blade part, 31, 31', 31'' are cutting blades of the cutter, and 25 is a mounting hole. 41-
44 is a cutting tool device for applying self-excited vibration to the cutting tool. To explain the operation of this structure, when producing short metal fibers 2 as shown in FIG. The grooving knife 30 and the grooving knife 20 are attached and cut in a stacked manner. When the cutting tool 41 moves forward and starts cutting,
First, the blades 21, 22, and 23 of the grooving blade 20 are provided at a constant interval L2 , and grooves as shown in 17 and 18 in FIG. 3 are cut into the metal block 40. Cutting blades 31, 31', 3 of the short metal fiber cutting blade 30 attached to the lower side of the blade
1'' starts cutting, and the short metal fibers are cut by the self-excited vibration of the cutting tool. In this case, since the grooves have been cut in advance by the cutting blades 21, 22, and 23 of the grooving tool, Spacing dimensions of cutting blades for groove cutting tools
Dimension of cutting width of cutter for cutting short metal fibers from L 2 L 3
Since L 3 > L 2 , the end face of the short metal fiber during cutting
Without being plucked off, short metal fibers with square end faces as shown in FIG. 1 and 2 are created. As another cutting method, screw cutting blades 50 and 51 as shown in FIG .
One that creates short metal fibers with a dimension of L 4 by cutting thread grooves with a spacing of L 4 , and then cutting the short metal fibers with a cutting blade for short metal fibers having a spacing larger than the spacing of L 4 . It is. In this case too, the metal block
Since the groove is cut with a dimension of L 4 , short metal fibers with square end faces can be manufactured.
以上述べた様に金属短繊維の製造に於てその端
部が鋭利な突状でない角型形状の所謂手で触れて
も危険のない金属短繊維を作るため金属ブロツク
に所定寸法の溝を切削しその後に金属短繊維切削
用刃物にて金属短繊維を切削すれば端面角型の直
線状の金属短繊維が連続的にバラツキが少なく製
造することが出来、かつ切削用刃物が極めて低コ
ストのために非常に効果のある金属短繊維の切削
工具である。 As mentioned above, in the production of short metal fibers, grooves of a predetermined size are cut into a metal block in order to produce short metal fibers that have a rectangular shape with no sharp protrusions and are safe to touch. If the short metal fibers are then cut with a cutting tool for cutting metal short fibers, linear short metal fibers with square end faces can be produced continuously with little variation, and the cutting tool can be used at an extremely low cost. This is a very effective cutting tool for short metal fibers.
