DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polishing method capable of inexpensively finishing the surface of various products (hereinafter, sometimes referred to as "abraded material") such as a metal plate, a shaped steel, a plywood and a synthetic resin plate. The present invention relates to a patterning surface finishing device.

[0002]

2. Description of the Related Art For example, a metal product such as a metal plate or a shaped steel will be described as an example. The surface finish is a surface finish such as a mirror finish, a blast finish, a color coloring finish, and a dull finish. However, a single patternless finish with no change was common.

[0003] The surface of a product subjected to such various surface treatments is a single finished surface with no pattern. Since the flaws were conspicuous and the commercial value was reduced, the flaws and the surrounding area were polished to make the flaws inconspicuous. They did not improve the value of the product.

Therefore, as an example, when the flaw portion and its surroundings are polished, the entire surface is further subjected to a hairline finish for forming a linear polishing mark to make the trace of the polished portion inconspicuous. I was

[0005] This hairline finishing is performed by a grinding wheel, which extends parallel to the surface to be polished of the material to be polished and substantially perpendicularly to the direction of transport of the material to be polished, over a substantially entire length of a rotating shaft whose axis is arranged.
Abrasive materials having relatively large abrasive grains such as synthetic fibers, nonwoven fabrics, and sandpaper containing abrasive grains can be fixed, or the abrasive can be placed between a plurality of rotating shafts arranged at an interval with the axial center thereof being in the above-described direction. A relatively large abrasive such as a ring-shaped non-woven fabric or sandpaper containing grains is spread over the abrasive, and the abrasive is rotated or rotated and pressed against the surface of the material to be polished. The polishing marks were applied to the entire surface of the material to be polished.

However, since the hairline finish applied over the entire surface of such a material to be polished is monotonous, various patterns having excellent design effects such as patterns such as slash-finish and frosted patterns are applied. There is growing demand for products.

[0007] However, since the work of applying a pattern or a frosted pattern such as the above-mentioned brushed finish must be performed manually by a worker using a brushed or hand-held sander,
Skilled workers are required to obtain a desired surface finish that gives rise to an aesthetic appearance, but very few skilled workers can perform such a desired surface finish. The surface finishing operation has the drawbacks that it takes time and labor, the production cost is extremely high, and the production efficiency is very poor.

Further, since the surface finishing is performed by an operator holding a tool in his / her hand, not only is the labor required for the operator large, but also a great mental load is required to finish the desired pattern. There was a disadvantage that this was the case.

[0009] The finish for forming a pattern on the surface of a product may be, for example, an etching finish capable of giving any desired pattern. This etching finish is performed by dissolving the surface chemically or electrically. Since it is a treatment, it requires pretreatment such as forming a masking material on the surface for partitioning into a part where the surface of the product is dissolved and a part where it is not dissolved when dissolving, and also requires a large amount of chemicals. There is a drawback that not only is labor required, but also waste liquid treatment is costly and very expensive.

[0010]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks of the prior art, and provides a method for producing a surface of a material to be polished, such as a metal plate, a shaped steel, a plywood, a synthetic resin plate, etc., such as a surface finish.

First, the ram moving mechanism of the plane moving device 11
Numerical control unit 12 and / or support frame moving mechanism 13
Abrasive material of a flap wheel 5 fixed to a rotary drive shaft 6 pivotally mounted on a frame 4 by actuation by 14
5a is positioned above the workpiece 15 at a desired initial position where the polishing marks 15a are to be formed.

That is, the ram 3 to which the frame 4 is pivotally attached at its lower end is hung down on the support frame 2.
Is movable along the support frame 2 in a direction orthogonal to the rail 1 by the ram moving mechanism 12 and the support frame 2 is movable along the rail 1 by the support frame moving mechanism 13. When the numerical control device 14 operates the ram moving mechanism 12 and / or the support frame moving mechanism 13 of 11, the grinding of the flap wheel 5 fixed to the frame 4, that is, the rotary drive shaft 6 supported by the frame 4 is performed. Lumber
5a can be positioned above the workpiece 15 at a desired initial position where the polishing marks 15a are to be formed.

More specifically, the numerical controller 14 operates the servo motor 12a of the ram moving mechanism 12 by a predetermined control amount to rotate the nut 12c mounted on the ram 3 and screw the nut 12c. Moving the ram 3 along the support frame 2 laid over the bed 16 via a nut 12c along a screw shaft 12b fixed to the support frame 2 and moving the support frame Servo motor 13 of mechanism 13
c is actuated by a predetermined control amount to rotate the pinion 13b mounted on the support frame 2 to move the support frame 2 along the rack 13a fixedly mounted on the rail 1 screwed with the pinion 13b. If one or both of the operations of moving the ram 3 are performed, the abrasive material placing surface 16a of the bed 16 is placed at the lower end of the ram 3.
The abrasive material 5a of the flap wheel 5 fixed to a rotary drive shaft 6 rotatably supported on a frame 4 mounted on a rotatable spline shaft 10a perpendicular to the shaft is positioned at a desired initial position. It can be done.

In this state, the turning device is arranged such that the rotary drive shaft 6 to which the abrasive 5a of the flap wheel 5 is fixed is located in a direction perpendicular to the direction of the abrasive marks 15a applied to the surface of the workpiece 15. The frame 4 is rotated by 10.

The turning device 10 is controlled by a numerical controller 14
By operating the servo motor 10a of the turning device 10 provided on the ram 3 by a predetermined control amount, the power of the servo motor 10a is attached to the frame 4 at the lower end of the ram 3 via the power transmission mechanism. By rotating the spline shaft 10b, the rotary drive shaft 6 supported by the frame 4 is positioned in the above-described direction.

Since a polishing pattern such as a pattern or a frosted pattern is applied, the operation of bringing the abrasive 5a of the flap wheel 5 into or out of contact with the surface of the workpiece 15 is supported by the frame 4, that is, the frame 4. When the entire heavy ram 3 is provided with a turning device 10 for turning the rotary drive shaft 6 to which the flap wheel 5 is fixed, the responsiveness is poor and the rotary drive shaft 6 to which the flap wheel 5 is fixed is poor.

Is used as a reference for the descent distance of the frame 4 by the lifting mechanism 9 for polishing by contacting the surface of the material 15 to be polished. If this difference is made as short as possible, the lifting stroke of the lifting mechanism 9 can be reduced. This is effective in reducing the load on the servomotor 9b of the first elevating unit 3b of the elevating mechanism 9 by making it shorter.

In order to preliminarily position the abrasive 5a of the flap wheel 5 at a predetermined position slightly higher than the surface of the abrasive 15 by lowering the frame 4 as described above, the thickness of the abrasive 15 is controlled by the numerical controller 14.

That is, with respect to the elevating mechanism 9, the servomotor 9b of the elevating mechanism 9 is operated by a predetermined control amount by the numerical controller 14 to rotate the cam 9a provided in the first elevating section 3b, thereby causing the cam 9a to rotate. Cam follower engaged with
The second lifting part 3c provided with 9c is moved up and down to lower the first lifting part 3b to a position where the abrasive 5a of the flap wheel 5 comes in contact with the workpiece 15 or contact the abrasive 15 with the abrasive 15a. The flap wheel 5 is raised to a position where the abrasive 5a of the flap wheel 5 is brought into contact with the workpiece 15 with respect to the first lifting / lowering portion 3b, and is raised to a position where the abrasive 5a is not in contact with the workpiece 15. The interval to be let is cam 9a
Can be set arbitrarily according to the shape of. The operation of raising and lowering the abrasive 5a of the flap wheel 5 by the raising and lowering mechanism 9 is reliably guided in the vertical direction because the raising and lowering mechanism 9 is provided with the guide member 9d.

Here, the number of rotations of the rotary drive unit 7, that is, the number of rotations of the flap wheel 5 fixed to the rotary drive shaft 6 rotated by the rotary drive unit 7, is determined by the polishing marks 15
It affects the shading of a.A high number of revolutions can form polishing marks 15a that express dark patterns, and a low number of revolutions can form polishing marks 15a that express light patterns. By controlling the servo motor 7a of the apparatus 7, the number of revolutions at which the polishing marks 15a corresponding to the desired light and shade patterns can be formed is set.

Here, the shading of the pattern means the deep grinding marks 15a.
A dark pattern appears due to the formation of pits or band-like polishing marks 15a, and a light pattern appears due to the formation of shallow polishing marks 15a or the formation of linear polishing marks 15a.

At this time, if the plurality of flap wheels 5 are fixed to the rotary drive shaft 6, a plurality of polishing marks 15a corresponding to the number of flap wheels 5 can be formed at the same time, so that the polishing operation can be performed efficiently. It can be carried out.

The support frame moving mechanism 13 is moved up and down while operating the lifting mechanism 9 by the numerical controller 14 to rotate the flap wheel 5 fixed to the rotary drive shaft 6 via the frame 4 by the rotary drive 7. In this state, the operation of moving the ram 3 in a direction perpendicular to the axis of the rotary drive shaft 6 to form a polishing mark 15a of a desired length is performed on the entire surface of the material 15 to be polished.

That is, the ram moving mechanism of the plane direction moving device 11
