Description

TECHNICAL FIELD The present invention relates to a mirror polishing device for a stainless plate, which polishes the surface of a stainless plate to give a mirror surface.

[Prior Art and its Problems] Conventionally, the mirror-polishing work of a stainless steel plate relies on manpower and is performed using a polishing buff. That is, the buff impregnated with the polishing liquid is moved while being pressed against the surface of the stainless steel plate for polishing.

However, since the polishing of the stainless steel plate is done manually, there is a problem that the work efficiency is extremely low and the productivity is poor.

Therefore, an object of the present invention is to provide a mirror-polishing device that automatically polishes the surface of a stainless steel plate to improve productivity.

[Means for Solving the Problems] In order to solve the above problems, a mirror polishing apparatus according to the present invention comprises: (a) a polishing table that supports a stainless steel plate on its upper surface, and the polishing table has a first electrode. (B) a conveying means for conveying the stainless steel plate in one direction on the polishing table; (c) a polishing means arranged so as to face the polishing table, and the polishing means is a buff for polishing the stainless steel plate. It has a rotating means for the buff and a second electrode; (d) a driving means for moving the polishing means in a direction orthogonal to the conveying direction of the stainless steel plate; (e) a polishing treatment liquid for the polishing means. And a supply / recovery means for supplying and recovering.

[Operation] When polishing the stainless steel plate, the stainless steel plate is fed onto the polishing table by the conveying means, and the polishing means is moved to the polishing start position of the stainless steel plate by the driving means. Then, the rotating means is driven to press the surface of the stainless plate while rotating the buff to start polishing. At this time, the polishing means is moved by the driving means in the direction orthogonal to the conveying direction of the stainless plate. Each time the stainless steel plate is polished in the width direction with a constant width, the conveying means is intermittently driven to move the stainless steel plate forward by a constant distance. At the same time,
Plating, electric and chemical polishing liquids are supplied from the supply / collection means onto the stainless steel plate through the polishing means, and an electric current is supplied through the first and second electrodes. By repeating the above polishing work, the entire surface of the stainless steel plate is mirror-polished.

The stainless plate may be continuously conveyed and the buff may be reciprocated in the width direction for polishing.

Therefore, the driving motor 27 is driven to drive the screw shaft 21d.
When is rotated, a screw nut (not shown) is moved to move the polishing means 10 attached to the holding member 24 in the width direction (direction orthogonal to the conveying direction of the stainless plate S). Reference numeral 28 shown in FIG. 2 is an encoder, which detects the number of revolutions of the screw shaft 21d to detect the position of the polishing means 10.

The polishing means 10 is for polishing the surface of the stainless steel plate S to a mirror surface, is provided with a buff 29, a polishing head 30, a drive motor 31, and a lifting cylinder 32, and is arranged above the polishing table 8. The buff 29 is made of an abrasive material that allows the polishing solution to easily penetrate, and is attached to a fixture 29a fixed to the lower end of the rod 33. The rod 33 has a key 33a in the longitudinal direction,
By engaging the key 33a with the key groove, the pulley 34 can rotate integrally with the pulley 34 and can move in the axial direction (vertical direction).

The rod 33 penetrates the polishing head 30, and the polishing treatment liquid fed from the liquid feed pump P described later is guided inside through the pipe 39, and an appropriate amount permeates the buff 29 and is supplied to the stainless plate S. To be done. The drive motor 31 is a rotation driving means for the buff 29, and is fixed to a mounting member 35 that is continuously provided on the upper end of the holding member 24.

Etc. to send an operation signal to automatically control the polishing work of the stainless plate S.

Next, the polishing work of the stainless plate will be described.

First, when the stainless steel plate S is moved from the previous step to the conveying means 7 side and is fed between the upper and lower feed rollers 13 and 14, the conveying motor 15 is driven to convey the stainless steel plate S in the direction of the arrow a for polishing. Send on the table 8. Here, the motor 15 is once stopped and the traveling motor 27 of the driving means 9 is driven to move the entire polishing means 10 to the right in FIG. 3 and brake at the polishing start position on the right side in FIG. The buff 29 is exposed to the right side of the tip of the stainless plate S.

Subsequently, the drive motor 31 of the polishing means 10 is driven to rotate the buff 29, the elevating cylinder 32 is driven to lower the buff 29, and the rotating buff 29 is pressed against the surface of the stainless plate S. At this time, the polishing treatment liquid is supplied from the polishing head 30 to the buff 29, and an appropriate amount is injected into the sliding contact surface between the buff 29 and the stainless plate S. Further, a direct current is supplied between the electrode 8b and another electrode 30b provided on the polishing head 30 to cause the electrolytic solution in the polishing solution to have an electric and chemical electrolytic action. As a result, the surface of the stainless steel plate S is promoted to be polished and finished with a glossy mirror surface by the plating solution.

Then, the traveling motor 27 is rotated at a low speed, and the buff 29 is polished while being moved in the width direction of the stainless plate S, that is, the left direction in FIG. When the polishing process to the left is completed, the transportation motor 15 is driven to rotate the rollers 13 and 14 by a certain amount,
The stainless steel plate S is slightly advanced.

Then, the traveling motor 27 is rotated in the reverse direction to move the polishing means 10 to the third position.
