Description

Barrel Polishing Apparatus of Low Speed

The present invention relates to a low speed barrel polishing machine, and more particularly, by forming a plurality of protrusion embossing protruding inwardly on the inner surface of the rotating container, the workpiece is different from the inner surface of the rotating container by centrifugal force and surface tension of water. It prevents sticking and prevents uneven wear of the workpiece while efficiently performing fine polishing and gloss due to uniform finishing, and minimizing maintenance cost by removing rubber coating on the side of the rotating container, and reducing the rotational speed of the rotating container from 20 to per minute. At the same time, it minimizes the noise during grinding operation and at the same time, it does not drop gravel or ceramic stones of 5mm in diameter, which are abrasives, due to their own weight. A low speed barrel grinding machine that is improved.

In general, for polishing barrels at high speed, various polishing methods and polishing apparatuses have been disclosed. The barrel grinding method commonly used in the industry is called barrel grinding or barrel finishing, in which a workpiece (water, abrasive and compound) is put into a barrel (an angle barrel made of wood or metal) for several hours. A method of continuously rotating or vibrating a cylinder to polish or polish the surface of the workpiece. The workpiece, abrasive stone, or stone is placed in a barrel (barrel grinder) called an octagonal or hexagonal barrel (also called a barrel barrel). Add water and compound and rotate or vibrate it. Then, inside the barrel, a flow motion occurs in the mixture (mass) of the workpiece and the abrasive stone, and pressure is applied. In this state, the surface of the workpiece is polished by rubbing each other.

These barrel grinders are dry and wet. Dry grinders have a high polishing rate while rough polishing surfaces, and wet grinders have only about one fifth the grinding speed, but the polished surface is precise. This processing method is capable of processing a large number of parts at the same time, and is used for removing burrs of all kinds of metals, trimming corners of edges, and finishing surfaces and polishes. It is also suitable for polishing a large number of small-sized workpieces or for surface grinding of a complex type of workpiece that cannot be polished by hand or by a grinder.

Among such barrel grinding machines, a general wet barrel grinding machine includes a fixed container, which is a main body, and a rotation spaced apart from each other with a small space between the fixed container and the same axis as the central axis of the fixed container and housed inside the fixed container. It is formed on one side of the container and the rotating container is provided with a sealing means for sealing the inlet which is a passage in which the workpiece is introduced into the interior and outflow after processing.

This wet barrel grinder removes impurities attached to the surface of the workpiece to be polished, mixes the abrasive stone and the abrasive powder in an appropriate ratio inside the rotary container, and then inserts the workpiece, and polishes the rotary container containing the workpiece and the mixture. Water is added to seal the inlet with a sealing means, and then rotated at a high speed to perform polishing and chamfering of the workpiece.

In this way, the workpiece and the mixture accommodated in the rotating container rise in the rotational direction by the rotation of the rotating container, and slide down by gravity near the central axis of the inside of the rotating container, and the inner surface of the rotating container As it circulates up and circulates up again by rotation, the workpiece is polished by the friction between the workpiece and the mixture and the inner surface of the rotating container by the above operation. In such a barrel grinding machine, the quality of grinding and chamfering of the workpiece is determined by the ratio of the workpiece and the mixture, the friction and the rotational speed of the inner surface of the rotating container, and the ratio and the rotation speed of the workpiece and the mixture. Can be adjusted according to the condition of the workpiece to be processed or the demand of the consumer.

In addition, barrel grinders, which use larger barrels and are installed in a horizontal state to polish the workpiece at a rotational speed of about 50 revolutions per minute, are also commonly used. As abrasives, gravel and ceramics having a diameter of about 5 mm are used. There was a problem that caused a lot of noise due to the use of the stone, and accordingly solved this problem by rubber coating the inner surface of the rotating container, but the additional cost of the maintenance work is added to the maintenance cost is quiet only when additional rubber coating is performed In the polishing operation due to the rotation of the rotating container, the gravel or ceramic stones fall down due to their own weight, which causes a problem in the workpiece, and also, the rotation of the rotating container causes the centrifugal force and It is attached to inner surface by surface tension of water By sticking been uneven wear of the workpiece it occurs there is a problem in that defects continuously occur.

The present invention is to solve the above problems, by continuously forming a plurality of protruding embossing protruding inward on the inner surface of the rotating container by the centrifugal force and the surface tension of water adhered to the inner surface of the rotating container. Prevents uneven wear of the workpiece while efficiently performing fine grinding and gloss due to uniform finishing, minimizing maintenance costs by removing rubber coating on the side of the rotating container, and reducing the rotational speed of the rotating container from 20 to 30 per minute. By minimizing the noise during grinding operation, at the same time, it is possible to greatly reduce the damage of the workpiece due to the dropping stroke according to the cloud, without the gravel or ceramic stones of about 5mm diameter, which are abrasives, falling down by their own weight. To provide a low speed barrel grinder The.
