[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rod-shaped body polishing method and a polishing apparatus for easily carrying out this polishing method.

[0002]

2. Description of the Related Art Generally, VTRs and Ds as information recording bodies
Magnetic tapes for AT, floppy disks for computers, etc. are made of polyethylene terephthalate (PE
Ni-based alloy or Co on a plastic film such as T)
A base alloy or the like is attached as a thin film by, for example, a vapor deposition method using an electron beam. In this case, Ni-based alloy or Co
The base alloy is used as a material in the form of a plate or rod,
Alternatively, it is used as a raw material in the form of pellets.

As a method of manufacturing this rod-shaped material, conventionally, in order to prevent the inclusion of impurities, melting and refining are performed in a vacuum, and a refractory material is cast as an ingot by an ingot case lined on the surface, It is known that primary processing (rough processing) such as slab forging and secondary processing (finishing) such as finish forging and rolling are performed to obtain a predetermined final product shape. Then, the oxide film is removed from the rolled product by polishing or the like to obtain a rod-shaped material.

By the way, in order to polish the outer peripheral surface of the rod-shaped rod-shaped material, for example, as shown in FIG.
1. A deformation centerless in which the rod-shaped material W supported on 1 is placed and sandwiched by the polishing wheel 102 and the rubber roller 103 which rotate in the same direction from both sides thereof, thereby rotating the rod-shaped material W and polishing the outer peripheral surface thereof by the polishing wheel 102. The polishing method of the method (centerless method) is used.

[0005]

By the way, in the above-mentioned prior art, the material to be machined is not particularly stable in shape as a bar-shaped material after hot working, and the outer peripheral surface of the bar-shaped material is further rotated while the bar-shaped material is further rotated. Since the polishing is performed, there is a problem that the outer peripheral surface cannot be satisfactorily polished because the rod-shaped material is shaken (developed) during the polishing. This problem becomes more remarkable as the outer diameter and the length of the rod-shaped material increase, and there has been a strong demand from the safety point of view to reduce the deflection.

The present invention has been made in view of the above problems of the prior art. Unlike the conventional centerless polishing, the outer peripheral surface of the rod-shaped body is polished without rotating the rod-shaped body so that the rod-shaped body under polishing can be polished. An object of the present invention is to provide a polishing method and a polishing apparatus for a rod-shaped body, which is capable of eliminating swinging of the body and satisfactorily polishing the outer peripheral surface in a short time to improve its roundness.

Further, in the prior art, since the rubber roller supports the rod-shaped body at one point, the polishing pressure on the rod-shaped body of the polishing wheel is limited, and the polishing pressure cannot be set high. However, there is also a problem that it takes a long time for polishing and productivity is low.

Therefore, another object of the present invention is to provide a polishing method and a polishing apparatus for a rod-shaped body, which can polish the outer peripheral surface of the rod-shaped body in a short time and improve productivity.

Rotation of the rod in the circumferential direction of the rod-shaped body.
Position the other parts relative to the elastic polishing body.
And a positioning step for
It is characterized in that the entire outer peripheral surface of the rod-shaped body is polished by sequentially repeating the positioning step .

In the present invention, since the rod-shaped body is not rotated during polishing, the rod-shaped body can be satisfactorily polished without being touched or exposed during polishing. Also,
Perpendicular to the axial direction of this rod-shaped body on one part of the outer peripheral surface
Pressing an elastic polishing body that rotates around
The rod-shaped body and the elastic polishing body relative to each other in the axial direction.
By making the rod-shaped body part of the outer peripheral surface of the shaft
It can be polished in the entire area of the direction. This one area

By supporting the rod-shaped body at a plurality of points at a plurality of points in the axial direction, the rod-shaped body can be stably supported and the polishing pressure of the elastic polishing body can be set high. Further, during polishing, the elastic polishing of the rod-shaped body is performed.
By pressing both sides of the body , the work can be supported more stably and its bending can be prevented. An example of the rod-shaped body is a rolled rod-shaped material made of a high-purity metal or alloy.

The work supporting means 2 supporting the work W is
The moving means 4 moves the work polishing means 3 toward the work polishing means 3, and the cylinder 23 is used to move the table 23 of the work polishing means 3 which was previously in the standby position by the cylinder 24.
The polishing wheel 28 of the work polishing means 3 is positioned directly above the work W by moving the work grinding wheel 28 to the base 14 side.
Here, by lowering the entire polishing unit 26 by the pressing cylinder 30, the polishing wheel 28 is pressed against a part of the outer peripheral surface of the work W on the work supporting means 2 with a predetermined polishing pressure, and a pair of pressers is pressed. Roller 36a,
By lowering 36b (for example, a rubber roller),
With the pair of presser rollers 36a and 36b, the work W
The parts on both sides of the polishing wheel 28 are pressed from above. In this example, the work W is stably supported at a plurality of points by the plurality of rubber rollers 19a to 19g and 20a to 20g as described above, so that the polishing pressure can be set high and the pair of pressing rollers 36a and 36b can be set. By work W
Can also be prevented from bending.

Next, by moving the work supporting means 2 between the strokes (the feed speed is, for example, about 0.5 to 5 m / min), one portion of the work W is axially moved by the polishing wheel 28. The entire region (see the polishing region a in FIG. 6) is uniformly polished. At this time, the pressing rollers 36a,
Since the work W is pressed by 36b, the work W does not bend and good polishing can be achieved. After completion of this polishing, the work supporting means 2 is once moved to the standby position, where the electric motor 21 causes the supporting rollers 19a to 19g, 20a to 2 to be moved.
The workpiece W is rotated by rotating the 0 g rotary shafts 16a and 16b in the same direction by a predetermined angle (45 ° in this example).

Thereafter, similarly to the above, the polishing regions c to h of the work W are sequentially polished to polish the entire outer peripheral surface of the work W. The polishing apparatus of the present embodiment uses the work W
Even when the outer diameter of the workpiece is changed, it is possible to polish works having various outer diameters without changing the design. In this example, the number of polishing regions a to h in the circumferential direction of the work W is eight.
However, the present invention is not limited to this, and is appropriately determined depending on the outer diameters of the work W and the grinding wheel 28. Since the polishing apparatus of the present embodiment does not rotate the workpiece W during polishing of the workpiece W, the workpiece W does not swing and the workpiece W can be polished well in a short time. Further, since a plurality of pairs (7 pairs in this example) of a pair of supporting rollers 19a and 20a for supporting the work W at two points are provided, the work W is stably supported and the polishing pressure is set to be high by the polishing wheel 28. As a result, the polishing time can be further shortened and the productivity can be improved.

After the polishing of the entire outer peripheral surface of the work W is completed, the work supporting means 2 is moved to the standby position, and the moving column 40 of the work conveying means 6 is moved to the work W side on the work supporting means 2 here. Accordingly, the plurality of horizontal work lifting members 45 are positioned below the work W. In this state, the work lifting members 45 are moved by the cylinder 43.
Respectively, the work W is slightly lifted by the respective work lifting members 45, and the moving body 41 is further lifted by the cylinder 43, so that the respective work lifting members 45
Is positioned near the upper end of the inclined plate 38 of the work storage means 5, and each work lifting member 45 is returned to the horizontal state by the cylinder 43, whereby the work W supported by each work lifting member 45 rolls. And is transferred onto the inclined plate 38. In this way, the polished work W is transported to the work storage means 5.

The polishing apparatus of this embodiment automatically performs all the steps such as supplying the work W to the work supporting means 2, polishing the work W, and transporting the work W after polishing to the work storing means 5. It can be done and labor saving can be achieved. Then, by repeating the above steps, a plurality of works W on the work supply means 1 can be sequentially polished.

In the above embodiment, the work supporting means is fed and moved to polish the work by the polishing wheel in a fixed position. However, the invention is not limited to this, and only the work polishing means, or the work supporting means and the work polishing means. The relative movement of the work and the grinding wheel may be ensured by feeding and moving both of them. Also, the number of support rollers and presser rollers is not limited to the above,
For example, it is appropriately set according to the length and diameter of the work. Furthermore, the polishing member is not limited to one that uses a polishing wheel, but a polishing member (for example, a polishing cloth) is pressed against the outer peripheral surface of the rod-shaped body, and at least one of the rod-shaped body and the polishing cloth is moved in the axial direction of the rod-shaped body. The entire outer peripheral surface of the rod-shaped body may be polished by reciprocating the movement. Then, as the work, the rod-shaped material for vapor deposition used when forming a thin film on the film surface by the vapor deposition method using an electron beam is given as an example, but the work is not limited to this, and a rod-shaped body such as a general metal rod or a resin rod is used. But it's okay. Also, not limited to a circular cross section,
It may have a polygonal cross section.
