Description of the Related Art As shown in FIG. 10, an O-ring a is formed by forming a rubber elastic body wire b having a circular cross section into a ring shape, and is shielded by being inserted into a bearing portion to which pressure is applied. Used as a material. This O-ring a is generally manufactured by sandwiching a material on a sheet between upper and lower molds, and immediately after this forming, as shown in FIGS. An outer burr c and an inner burr d are formed on the outer circumference and inner circumference of the element wire b, respectively.
Since such burrs c and d are in the form of a thin film, most of them can be easily peeled off. However, if the burrs c and d that have spread greatly are simply removed by hand, small burrs c and d of less than 1 mm may remain on the inner and outer peripheries of the strand b. Then, in the shield portion to which pressure is applied, even such small burrs c and d may possibly hinder the sealing, so that it is necessary to completely remove these burrs.

The burrs c and d can be completely removed by applying a strong impact in a state where the burrs c and d are sufficiently hardened by being frozen once after production. However, such a method of freezing the O-ring a deteriorates the material of the surface of the wire b by the freezing process, and therefore cannot be employed in the O-ring a for precision equipment used in an aircraft or the like. . Therefore, in the conventional O-ring a for precision equipment, the outer burr c or the inner burr d is manually removed by a skilled worker using a luter (grinder). That is, the worker slides the inner and outer peripheral surfaces of the O-rings a with the rotating grindstone surface of the luter while a large number of the O-rings a are fitted to the fingers. Then, a delicate friction is generated between the finger and the O-ring a, and a difference in peripheral speed is generated between the O-ring a and the grindstone surface. The inner burr d on the inner peripheral side was removed by grinding.

を招いていた。However, the method of removing the outer burrs c and the inner burrs d by the above manual work is not only extremely delicate and requires a high level of skill, but also is inefficient and troublesome for a skilled worker. Therefore, there has been a problem that poor productivity in the step of removing the outer burrs c and the inner burrs d is an obstacle to cost reduction of products. In addition, in this manual operation, talc is attached to a finger in order to generate appropriate friction between the O-ring a and the talc. Therefore, a cleaning step for removing talc attached to the O-ring a is newly added. There was also a problem that talc that became necessary or was scattered during work deteriorated the work environment. Further, the surface of the O-ring other than the burrs may be cut, resulting in a decrease in quality.

An object of the present invention is to provide a method for removing burrs from a ring.

寸法の約２倍としているが、勿論これに限らない。As shown in FIG. 2, the small pulley 3 is provided with a V-shaped or U-shaped peripheral groove 7 on the outer peripheral surface 6 thereof, and the O-ring 1 is fitted into the peripheral groove 7. As shown in FIG. 3, the large pulley 2 has a linear outer peripheral surface 8 having a linear cross section, and the O-ring 1 is engaged with the outer peripheral surface 8.
In this case, the large and small pulleys 2 and 3 are arranged on the same vertical plane. Further, the outer diameter of the large pulley 2 is about twice as large as the outer diameter of the small pulley 3, but is not limited to this.

As shown in FIG. 4, not only the O-ring but also a plurality of pulleys 15 are provided.
The belt 16 (the flat belt or the like) wrapped around is trying to climb to the large diameter side. However, tension of belt 16 and pulley 15
Due to the relationship between friction and the belt 16, if the climbing limit is exceeded, the vehicle slips back to its original position, and as a result, the O-ring 1 and the like roll. In the case where the cross-sectional shape of the outer peripheral surface 8 is linear, like the large pulley 2, the O-ring 1 and the like do not roll and maintain the original state.

きる。The inner burr grindstone member 4 and the outer burr grindstone member 5 are each formed of a disk, and in the case of the inner burr grindstone member 4, the inner burr of the O-ring 1 on the large pulley 2 side. The O-ring 1 is disposed near the O-ring 1 by a drive mechanism (not shown), and the inner burr 1a of the running O-ring 1 is polished by a rotational drive around the axis as shown in FIG. In the case of the outer burr grindstone member 5, it is disposed on the outer peripheral side of the O-ring 1 on the side of the large pulley 2, and approaches and separates from the O-ring 1 by a drive mechanism (not shown). And FIG.
As shown in (1), the outer burr 1b of the running O-ring 1 can be polished (cut) by the rotational drive about the axis.

To the inner peripheral side and the outer burr 1b to the outer peripheral side.
Then, after the inner and outer burr grinding stone members 4 and 5 are brought into contact with the burrs 1 a and 1 b of the O-ring 1, respectively, the large pulley 2 is rotationally driven to move the O-ring 1 as shown by arrows A in FIGS. 6 and 7. And run.

速は例えば50ｍ／min 程度としておく。At this time, the rotation of each of the inner and outer burr grinding stone members 4 and 5 is set to a free state, and the inner and outer burr grinding stone members 4 and 5 are rotated by the frictional force with the O-ring 1. In other words, the peripheral speed (rotation speed) of the O-ring 1 and the peripheral speed (rotation speed) of each of the inner and outer burr grinding stone members 4 and 5 are matched. At this time, the peripheral speed of the O-ring 1 is set to, for example, about 50 m / min.

a, 1b is polished (cut). That is, the speed obtained by subtracting the peripheral speed of the O-ring 1 from the peripheral speed of the grindstone members 4 and 5 is the polishing (cutting) speed.

取り作業が終了する。When the deburring is completed, on the contrary, first, the rotational drive of the grindstone members 4 and 5 is stopped, and the grindstone members 4 and 5 are set in a free state. That is, the peripheral speed of the grindstone members 4 and 5 is made to match the peripheral speed of the O-ring 1. After that, the rotation of the large pulley 2 is stopped to stop the running of the O-ring 1, and the grindstone members 4 and 5 are separated from the O-ring 1, so that the O-ring 1
Is removed from the large and small pulleys 2 and 3, the deburring operation of the O-ring 1 is completed.

If a and 1b are polished, the O-ring 1 can travel along the small and large pulleys 2 and 3 without meandering and rolling during polishing (cutting).
b can be reliably removed. Moreover, FIG.
The biting portion 9 as shown in (b) is not formed on the O-ring 1. On the other hand, when the rotating grindstone members 4 and 5 are brought into contact with the running O-ring 1, the flash 1
The surface of the O-ring 1 other than a and 1b was cut, and FIG.
(A) The biting portion 9 as shown in (B) is formed.

In this case, the grindstone members 4 and 5 include a grindstone main body 11 having a semicircular concave circumferential groove 10 formed on an outer peripheral surface thereof, and an abrasive 12 buried in the bottom of the concave circumferential groove 10 of the grindstone main body 11. Consists of Therefore, in the case of the inner burr whetstone member 4, it is disposed on the inner peripheral side of the O-ring 1 on the side of the large pulley 2 and is driven to rotate around its axis so that the inner peripheral portion of the running O-ring 1 becomes The outer burr 1a can be polished (cut) by the abrasive 12 by being fitted into the concave circumferential groove 10. In the case of the outer burr member 5, the outer peripheral side of the O-ring 1 on the large pulley 2 side And the outer peripheral portion of the running O-ring 1 is fitted into the concave circumferential groove 10 and the outer burr 1b is polished (cut) by the abrasive 12 )can do.

It can be changed by changing the material of the ring 1, the wire diameter, the circumference, and the like, or by changing the distance between the pulleys 2 and 3 between the shafts. If the tension is large, the peripheral groove 7 of the small pulley 3 rolls up the O-ring 1 and falls down, and the burrs 1a and 1b cannot be reliably cut. Conversely, if the tension is small, the O-ring 1 Therefore, the tension of the O-ring 1 needs to be set to an appropriate value in consideration of the above-mentioned materials and the like.
