A deburring method in which deburring is performed sequentially using two types of rotary cutters having m-cutting blades with a concave shape that is almost the same as the shape of the deburring device. 1st
As shown in the figure, it is formed into a substantially ring shape when viewed from above, and the mating surfaces of the substantially ring-shaped members (with a slight gap 1) are shown in FIGS. 2A and 2B. Joining is performed by flash butt welding. In joints made by such flash butt welding, a burr 2 is generated in which the welded part protrudes from the outer surface, but this burr 2 must be completely removed by pressing, which is a post-processing process. In other words, it is necessary to remove the pad 2 at the welded joint to form a complete ring-shaped member, and then press-work the member.

にパリ2をそぎ落していくようになされていた。In order to remove the gap 2 at the welded joint of the ring-shaped member, conventionally, a plurality of shearing molds corresponding to the cross-sectional shape of the ring-shaped member are used, as shown sequentially in FIGS. 3A to 3D. 3A (approximately 315 out of the entire circumference) by moving the part relative to the member, and then shave off the part 2a in Fig. 3A (this is about 315 out of the entire circumference), and then cut off the part with another shear die. Cut off the part marked 2b in Figure 3B, and then add the third part.
Paris 2 was removed in sequence, such as the part 2C and the part 2d in Figure C.

、パリを削シ取るものである。Another conventional technique, as shown in FIG. 4, is a technique for removing weld burrs exclusively from large-diameter members, such as ring-shaped members for car handles. In this technique, another gear 4 is meshed with the outer circumference of a deburring gear 3 having a cutting edge formed on its inner periphery and driven to rotate, and the cutting edge on the inner periphery of the former gear 3 is used to scrape off the deburr. It is.

のにすることにある。However, although this technique is efficient, it can only be applied to large-diameter ring-shaped members due to mechanical reasons, and it is also difficult to apply to the discharge of deburring chips and the production of the deburring gear 3. Difficult issues remain.The present invention was made in view of the above problems and proposes an advanced deburring technology for welded joints of ring-shaped members.The purpose of the present invention is to simplify the deburring work. and to make it efficient.

る。For this purpose, the present invention basically cuts welding edges using two types of rotary cutters each having a multi-zero cutting edge having a concave shape that is approximately the same as the shape of the inner circumferential side cross section and the outer circumferential side cross section of the ring-shaped member. It is designed to remove the spots in sequence.

ある(そうしないと、パリの削シ残しが生じてしまう。A feature of the present invention is the use of a so-called general rotary cutter. These rotary cutters are illustrated in FIGS. 7A and 7B, and the rotary cutters have a thread number Φ cutting blades 5 (for example, 10 blades), and these cutting blades 5 (
The material may be cemented carbide or the like. ), as shown in Fig. 7B, and also in Figs. 5B and 6B, is a cutting edge surface having a concave shape that is almost the same as the shape of the outer circumferential side or inner circumferential side cross section of the ring-shaped member. There is. That is, the ring is
The cutting blades 5 of the two types of rotary cutters each have a cutting surface formed in a concave shape that is approximately half of the cross section of the ring-shaped member, in other words, approximately the same as the cross section of the outer circumferential side or the inner circumferential side. The reason why I say ``habo'' here is because the cutting edge actually covers more than half of the cross section of the ring-shaped member (otherwise, there would be uncut edges left behind).

障なく適用できる。It does not require any particular difficulty to configure the cutting edge of the cutter as described above. Furthermore, as is obvious from FIG. 6A, the outer diameter of the cutter for cutting off the inner circumferential edge is smaller than the inner diameter of the ring-shaped member. In addition, it is generally easy to manufacture a full-form cutter with a small overall outer diameter, so the technique of the present invention can be applied to small-diameter ring-shaped members without any problems.

面よシも少し越えた処までパリが削り落とされる。Did you do the above? ff1ff) Describing the method of the present invention using a rotary cutter, first, the welded joint of the ring-shaped member that is the work is gradually pushed against the cutting edge 5 of the cutter toward the center of the cutter, as shown in FIG. 5A. Can be guessed. In addition,
This pressing work may be done manually, but
This can be easily done using a suitable handling robot. Furthermore, the method of the present invention is suitable for performing deburring work while automatically moving the workpiece. The debris pressed against the rotating cutter is scraped off at high speed by the cutting blade 5, and at this time, the debris is scraped off to a point slightly beyond the outer circumferential cross-section of the ring-shaped member.

はない。Next, as shown in FIG. 6A, the ring-shaped member is positioned so that the edge of its inner circumference faces the center of the cutter, and is similarly pushed gradually toward the center of the cutter.
The inner peripheral surface is scraped off. It should be noted that it is completely arbitrary whether to start removing the edges of the ring-shaped member from the outer periphery side or from the inner periphery side. There are no restrictions on the order.
