上げて作られている。 A conventional belt polishing apparatus will be explained using chamfer polishing of a cylindrical workpiece as an example. As shown in FIG. 1, the abrasive belt 1 is movable relative to the workpiece W, and the cylindrical workpiece W is held at its ridge W1 by a posture holding means (not shown). , so that it can be rolled while facing the abrasive belt 1. A platen 2 is provided to this workpiece W via the abrasive belt 1 . Since this platen 2 comes into sliding contact with the polishing belt 1, in order to prevent damage due to this sliding contact, it is made of a material having a low coefficient of friction and high rigidity, such as a smoothed steel plate.

なり、面取りが不可能になる。 For chamfering, the abrasive belt 1 is run, and the workpiece W is rolled while its ridge W1 is pressed against the abrasive belt 1. Then, the ridge W 1 is shaved off and so-called chamfering is performed, but in this case, the chamfered portion is an annular surface W inclined at a certain angle with respect to the central axis of the workpiece W, as shown in FIG. 2 , and an annular ridge W 3 is formed between the end face and the outer circumferential face. In such chamfering, since there is a clear sharp ridge W 3 , burrs are likely to occur first on this ridge W 3 . Secondly, due to this ridge, when the workpieces W collide with each other, there are problems such as dents occurring. Also, in order to eliminate this sharpness, it is possible to make the platen 2 from a material with low rigidity.
In this case, the frictional force becomes large and the abrasive belt 1 or platen 2 itself is abrasively worn, and eventually sliding contact with the abrasive belt 1 cannot be performed smoothly, and chamfering becomes impossible.
上述のように、従来の面取りは、不具合な点が

要していた。 As mentioned above, conventional chamfering has many disadvantages and requires a lot of cost to deal with burrs, ridges W 3 , dents, etc. that still exist even after chamfering.

This allows for polishing without sharp edges.

うになつている。 As shown in FIGS. 3 and 4, the polishing device has a long belt-shaped endless polishing belt 1 with one surface serving as a grinding surface. The polishing belt 1 is driven by a drive mechanism (not shown) to continuously run in a constant direction at a constant speed, and comes into pressure contact with the workpiece W to polish the workpiece W. On the grinding surface of the abrasive belt 1, a guide 10 having an elongated flat plate shape as a whole is provided at an angle of about 45 degrees with respect to the running direction of the abrasive belt 1. This guide 10 is attached to the long side of a rectangular rod-shaped member.
A pair of guide rails 1 forming a 45° slope
1 and 11, each with an inclined surface as shown in the figure,
They are mounted on a pedestal (not shown) facing upward and facing each other with a constant gap between them. Also,
A platen 12 is provided along the abrasive belt 1 to this guide 10 . This platen 12 is
The polishing belt 1 is installed at an interval approximately equal to the thickness of the polishing belt 1 with respect to the guide 10, and the polishing belt 1 runs between the guide 10 and the guide 10 while its back surface is in sliding contact with the platen 12. The width of the platen 12 is wider than the width of the abrasive belt 1, and its length is large enough to allow the guide 10 to cross from one side to the other in the width direction, and is made of a highly rigid material such as a metal plate. The material is made of a material whose surface on which the abrasive belt 1 comes into sliding contact is finished to be smooth. Therefore, the surface of the platen 12 on which the abrasive belt 1 slides has a slope with a constant width dimension, facing the gap between the pair of rod-shaped members constituting the guide 10 and in the same direction. A V-shaped strip groove 13 having a surface is provided extending from one side of the platen 12 to the other side. However, this belt-shaped groove 13 is
The guide rails 11, 11 have a depth at which the abrasive belt 1, which bends due to pressure contact with the ridge portion W1 forming a part of the workpiece protruding from the gap between the guide rails 11 and 11, does not come into contact. Note that this device has a guide 10 for guiding the cylindrical workpiece W.
A press-contact rolling mechanism (not shown) such as a rotary belt is provided to roll the workpiece W along the abrasive belt 1 while being pressed against it, and as the workpiece W comes into press-contact with this mechanism, the workpiece W is moved from one side of the platen 12 by the guide 10. The other side is adapted to roll in a direction across the abrasive belt 1.

以上詳述したように、極めて実用的な多くの効果
を奏するものである。 In this polishing process, a band-shaped groove 13 is provided in a portion of the platen 12 that faces the guide 10 and the polishing belt 1, and the depth of the band-shaped groove 13 is determined by the pressure contact of the ridge W1 of the workpiece. Abrasive belt 1
Even if it bends, it is deep enough so that it does not come into contact with the ridge.
W 1 does not contact the platen 12 of the abrasive belt 1;
The part that bends into the free-form surface will be polished. That is, since it is curved so as to cover the ridge W 1 and comes into contact with and polishes a wide area, the chamfered surface is curved and does not have a clear ridge W 3 as in the conventional case. FIG. 5 shows an enlarged view of this situation. An example of the shape of an actual annular surface W2 that has been chamfered and polished using the apparatus of the present invention is shown in FIG. 6, enlarged (230 times larger than the actual surface). It can be seen that when the belt polishing device of the present invention performs the polishing process, both ends of the annular surface W2 become sharp, as if there were no ridges, and form a continuous smooth curved surface from the end surface to the outer peripheral surface. Since the edges of the processed parts are not sharp, no dents occur even when the parts are brought into contact with each other, and flow processing can be easily performed. This eliminates the need for processes such as , hammering, etc., and the productivity of polishing work can be dramatically improved. Further, in this polishing process, damage to the polishing belt 1 caused by the workpiece ridge W 1 when the workpiece W rolling on the guide 10 comes into contact with the polishing belt 1 can be alleviated. That is, when the conventional platen 12 does not have the band-shaped grooves 13, when it comes into contact with the sharp ridge W1 , it does not escape and easily damages the side edges of the polishing belt 1, but with the band-shaped grooves 13, the polishing Since the belt 1 bends there, damage can be significantly alleviated. Also, the width of the platen 12 is the same as that of the polishing belt 1.
If the width is equal to the width of the polishing belt 1, the amount of polishing will fluctuate when the polishing belt 1 oscillates laterally, but since the width of the platen 12 is larger than the width of the abrasive belt 1, the amount of polishing remains constant even when the belt 1 oscillates laterally. Therefore, the polishing to form the edge portion W1 of the workpiece into a continuous smooth curved surface can be performed uniformly and with good quality. Further, during this polishing process, the polishing belt 1 comes into sliding contact with the platen 12, and since the sliding surface of the platen 12 is hard and smooth, the sliding contact can be made smoothly. Furthermore, since the polishing process is performed while crossing the polishing belt 1,
The abrasive belt 1 is used without waste. This idea is
As described in detail above, it has many extremely practical effects.
