Description of the Related Art As shown in FIGS. 3 and 4, for example, a broach 20 is used as a machining tool for a nut bearing surface 4 of a link 3 in an endless track zone of a construction machine. The conventional broach 20 has an integral structure in which the blade 2 is integrally attached to the main body 1 as shown in FIG.

することにある。However, the conventional broach has the following problems. When the blade portion 2 is worn, it is polished and reused. However, if it is polished several times, the rigidity is insufficient, so that the blade portion 2 is discarded. When the life of the blade portion 2 has come, the entire body 1 has been discarded.
For this reason, a new body must be purchased. Broaches are about 2 meters long and are quite expensive. When used on a production line, the broach replaces a new (or polished) blade as the wear of the blade progresses. At this time, the main body must be removed after the line stops, and the stop of the production line and the replacement of the broach reduce the production efficiency. Due to differences in product (link) dimensions, several types of brooches must be kept on hand, which is costly. An object of the present invention is to provide a broach that requires only replacement of the blade portion.

(1) A broach in which the blade portion of the broach and the main body are configured separately, and the blade portion can be attached to and detached from the main body. (2) The broach according to (1), wherein the blade portion is divided into a plurality.

In addition, when replacing the blade, only the blade can be replaced while the main body remains attached to the equipment (machine tool), so that blade replacement can be performed easily and in a short time. In addition, since only a few blades need to be kept in stock, the stock is reduced as compared with the related art in which several types of broaches have to be kept in stock. In the cassette type broach of the above (2), since the blade portion is divided into a plurality of portions, only the worn portion can be replaced, which is more economical.

のからなる。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A broach according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 1 and 2, a broach 10 according to an embodiment of the present invention is configured such that a blade portion 12 and a main body 11 other than the blade portion 12 are formed separately from each other, and the blade portion 12 is attached to the main body 11. It consists of one that can be attached and detached.

ークへの喰込み深さが大である。The main body 11 has attachment portions 11a and 11b to equipment (machine tool) at both ends, and has an intermediate portion 11c between them. The intermediate portion 11c is a concave portion having a bottom, and the blade portion 12 is removably inserted into the concave portion. It is fixed by screws 13 and the like.
Attachment / detachment of the blade portion 12 to / from the main body 11 can be performed while the main body 11 is attached to equipment (machine tool).
Further, a plurality of blade portions 12 are provided in the longitudinal direction (for example, 3 to
(4 pieces) so that it can be partially replaced. The depth of the blade portion 12 into the work is greater as the blade is located rearward in the processing direction.

に比べて、経済的である。When the blade portion 12 is worn by a number of cutting operations, only the worn blade portion 12 is replaced with a new blade portion 12 or a polished blade portion 12. The main body 11 is used repeatedly without replacement. Replacement of the blade part 12 is performed by the main body 11
Is carried out with the equipment attached. For this reason, the replacement work time is shortened compared to the conventional case where the whole body was replaced,
Line down time is shortened and production efficiency is improved. Therefore, it is more economical than the conventional case where the entire system is abolished.
Also, since only some blades need to be stocked, it is more economical than the conventional case where the entire blade must be stocked.

さらにコストダウンをはかることができる。According to the broach of the first aspect, the blade portion and the main body are formed separately, and the blade portion can be attached to and detached from the main body (a cassette type). The cost can be reduced by sharing the main body and replacing only the blade. Further, since the blade portion can be replaced while the main body is fixed to the equipment, the replacement is facilitated and the replacement time can be shortened. According to the broach of the second aspect, since the blade portion is divided into a plurality of portions, it is sufficient to replace only the worn blade portion in replacement at the time of broach wear, compared to replacing the entire blade portion.
Further cost reduction can be achieved.
