Description

Vibration Barrel Finishing Machine

The present invention relates to a vibrating barrel grinding machine, and more particularly, to a vibratory barrel grinding machine capable of increasing polishing efficiency by improving the structure inside a barrel having a space for accommodating an abrasive and a material to be polished or a compound to be polished. .

Various types of machine parts, including industrial machines, perform various types of processing. For example, machining operations such as forging, cutting, grinding, and drilling are performed.

Here, polishing is a method for improving the degree or roughness of the product surface.

One of these grinding methods is barrel grinding. That is, the barrel grinder is a device for grinding by putting the product to be polished together with the grinding stone in a barrel (a region having an accommodation space) called a barrel.

The main purpose of barrel grinding is to remove the sharp surplus area (bur) by cutting to improve the surface roughness. I want to induce a good coating of the plating material by grinding, but the required process is the barrel polishing process.

Broadly dividing the types of these barrel grinding machines, it can be divided into a rotary barrel machine, a vibrating barrel machine and a vortex barrel machine.

The rotary barrel grinds the abrasive by rotating at a set speed (for example, 45 to 55 rpm) with a grinding stone, compound, and product in it at a constant speed.

The vibration grinder is a device that grinds the grinding stone and the product by giving it vibration in a set constant direction and intensity.

The easiest example of the vortex barrel machine is the same principle as the washing machine, and the product and the grinding stone that are swept into the water inside the rotating circular barrel create a vortex and grind against each other.

Among these barrel grinders, in particular, the vibratory grinder can work automatically, so its utility is high, and it would be desirable to further improve the utility and surface roughness of this vibratory barrel grinder.

The vibration barrel grinder 100 (hereinafter referred to as 'barrel grinder') according to the present invention will be described in detail with reference to FIGS. 1 to 5B as follows.

1 is a plan view and a side partial cross-sectional view of a barrel grinder according to an embodiment of the present invention, FIG. 2 is a cross-sectional view for explaining various embodiments of a high area of a cross-section of the present invention, and FIG. 3 is another embodiment of the present invention A plan view and a side partial cross-sectional view of a barrel grinder according to an example, FIG. 4 is a conceptual diagram for explaining a cross-sectional shape in a barrel according to another embodiment of the present invention, and FIGS. 5A and 5B are in another embodiment It is a plan view, a side load side view, and a front cross-sectional view of the barrel grinder according to the following.

One embodiment of the barrel grinding machine 100 according to the present invention, as shown in FIGS. 1 and 2, mixes an abrasive and an abrasive and includes a barrel 111 for guiding the abrasive and the abrasive to move. Polishing machine body 110 and; a driving unit 117 coupled to the polishing machine body 110; a support 130 for supporting the polishing machine body 110; An elastic member 150 having one side coupled to the support 130 and the other side coupled to the polishing machine body 110 to transmit the vibration force of the driving unit 117 to the abrasive and the abrasive material; It is preferable that the cross-section (refer to 'Ia-Ia cross-section' in FIG. 1) cut along the vertical direction of the central axis of the barrel 111 is discontinuous. The shape of the cross section may be provided in various forms, but the height gradually increases in the low region 163 and the low region 163, such as a wave shape, to have a high region 165, and the low region 163 and the high region It is preferred that the region 165 is continuously formed along the central axis of the barrel 111 .

Here, the barrel grinder 100 is, as shown in FIG. 1, an inlet 113 into which the abrasive and the abrasive are put in the center including the central axis of the grinder body 110 (refer to 'CL' in FIG. 1). In accordance with the operation of the driving unit 117 and the elastic member 150, the central axis of the barrel 111 having a snail shape and gradually increasing the radius of curvature, the abrasive (including a compound for grinding, water, etc.) and the abrasive move while the A discharge port 115 is provided.

And, in the barrel grinding machine 100, the driving unit 117, the elastic member 150, and the support unit 130 are well-known contents and are not the core of the present invention, so detailed descriptions will be omitted below.

That is, in the barrel polishing machine 100 of FIGS. 1 to 3 according to an embodiment of the present invention, the abrasive and the abrasive are continuously fed into the inlet 113 and polished while moving along the snail-shaped barrel 111 . An automatic type that is discharged to the outlet 115 is preferable.

It is preferable that the cross-section has a shape such as a wave shape while partially lining or coating with rubber or urethane on the lower side of the barrel (usually a 'U'-shaped cross-section as shown in FIG. 2). Although the shape of the cross-section is gently circular, it is of course also possible to have a straight shape from the low area 163 to the high area 165 .

In FIG. 1, the line connecting the lower region 163 (the portion indicated by a 'dotted-dotted line' between the high regions in the plan view of FIG. 1) or the high region (165, the portion indicated by the 'dotted line' in FIG. 1) is the polishing machine body 110 ) is preferably directed toward the central axis CL.

That is, a low region exists between the high region 165, and the line extending from the high region 165 and the low region 163 to the central axis CL of the polishing machine body is 360 degrees radially with respect to the central axis CL. It is preferable to be disposed at a position (refer to 'α' in FIG. 1) divided by a set size. According to this structure, while the abrasive and the abrasive material stably move along the barrel 111, the abrasive process can be more effectively performed by turning while stagnating somewhat between the cross-sections due to the structure of the cross-sections.

Here, looking at the shape of the high region 165 along the central axis of the barrel 111 in detail with reference to FIG. 2 , the center of the upper end is somewhat concave as shown in FIG. A shape in which the center is somewhat convex, or a shape in which concave and convex shapes are alternately arranged), a shape with a straight top as shown in FIG. See 'K1' in c), or, although not shown, the inner side is slightly higher than the outer side, or the high and low shapes are alternately arranged), a shape with a straight top but a concave shape with only the central region as shown in FIG. 2(d) (Although not shown, the upper end is provided with a straight line, but only the central region has a convex shape, or a shape in which concave and convex shapes are alternately arranged) and the like. Such a shape may be selectively adopted in consideration of the type, size, type, material, size, etc. of the abrasive material. Here, the part marked 'in' in FIG. 2 means the inside of the barrel 111 facing the central axis, and the part marked 'outside' means the outside of the barrel 111 away from the central axis.

As a result of operating the barrel grinder 100 having such a configuration, the effects identified by the present inventors are as follows.

When the diameter of the outer diameter of the barrel polisher 100 as shown in FIG. 1 is about 2100 mm, it is assumed that the capacity accommodated in the barrel 111 is about 600 liters.

)'로 만드는 경우, 외형의 직경이 약 2100mm 2대를 연속적으로 가공하여야 하고 이 경우 각 바렐 연마기 당 소요되는 시간이 약 10분이었다. 즉, 첫 연마기에서 연마조도(표면거칠기) 1.6a(

)로 연마한 후 다음 연마기로 피연마재를 연속적으로 연마를 하여야 필요로 하는 연마조도(표면거칠기)인 '0.2a(

)'를 달성할 수 있었다. First, according to the conventional barrel grinder (the wave-shaped cross-section is not formed inside the barrel as in the present invention), the abrasive and the abrasive are continuously polished to reduce the abrasive roughness (surface roughness) of the abrasive to '0.2a (

)', two units with an outer diameter of about 2100mm should be processed continuously, and in this case, the time required for each barrel grinder was about 10 minutes. That is, the grinding roughness (surface roughness) 1.6a (

) and then continuously grind the material to be polished with the next grinder, which is the required grinding roughness (surface roughness) of '0.2a (

) could be achieved.

)'로 됨을 확인할 수 있었다.On the other hand, in the case of using the barrel grinder 100 as shown in FIG. 1 having a wavy cross section according to the present invention, the required time per machine was 15 minutes because the speed was slowed down due to the presence of the cross section, but the finally polished product was Set the desired grinding roughness (surface roughness) to '0.2a (

) was confirmed.

In conclusion, in the case of the present invention, it was found that the treatment time was reduced from 20 minutes to 15 minutes compared to the prior art in achieving the same treatment capacity and required surface roughness (surface roughness). According to the present invention, it was confirmed that a large number of barrel polishing machines 100 could be used with a single barrel polishing machine 100 .

That is, the cross section according to the present invention induces some resistance to the transfer in the moving direction in the process of passing the high and low regions of the abrasive and the abrasive, so that the transfer of the abrasive and the abrasive is transferred from the inlet 113 to the outlet ( 115), and the transport speed is somewhat delayed compared to the prior art, but the abrasive and the abrasive can continuously induce more rotation, rotation, and friction, thereby increasing the overall polishing efficiency.

On the other hand, the barrel grinder 200 and 100 according to another embodiment and another embodiment of the present invention, as shown in FIGS. 3 and 4, has the same configuration as the barrel grinder 100 described above and has a high cross-section. The shape of the region 265 and the lower region 263 with respect to the central axis CL is different.

In the following embodiments, if there is no special description with respect to the reference numbers, the same configuration (for example, '110' and ' 210' refers to a 'polishing machine main body' since the tens unit and the unit unit of the reference number are the same), and a detailed description of this configuration will be omitted.

First, the line connecting the low area 263 of FIG. 3 or the line connecting the high area 265 (see part 'K' in FIG. 3 ) is directed toward the center of the central axis line CL of the grinder body 210 . It is preferable to include a spiral shape forming a parabola.

Next, the line connecting the lower region (not shown) of FIG. 4 or the line connecting the higher region 165 is preferably spaced apart from the center of the central axis of the grinder body by a set distance (refer to 'X1' in FIG. 4). Do.

On the other hand, Figures 5a and 5b are shown with respect to the barrel grinding machine (300, 400) operated manually or semi-automatically, the shape of the cross-section is a structure corresponding to the shape of Figures 1 and 3 described above.

In the above, the line connecting each of the low regions or the lines connecting each of the high regions was directed toward the central axis, but as shown in FIG. 6, when the barrel (not shown) overlaps in multiple layers with respect to the central axis (not shown), all layers Even if the line extending from the low area 565 or the high area 563 does not face the same central axis in all folds as in FIGS. 1 to 3, it does not impair the technical idea of the present invention.

Although not shown, the technical idea of the present invention is not applied only to the cylindrical barrel grinder, and it is preferable that the coating or lining be coated or lined in the shape of the cross-section described above on the inside of the barrel lower side of the long rectangular barrel grinder.

Accordingly, according to the present invention, it is possible to provide a vibration barrel polishing machine capable of improving the polishing degree or roughness.

In addition, it is possible to provide a vibration barrel polishing machine capable of reducing the time required to maintain the same polishing degree or roughness.

In addition, it is possible to provide a vibrating barrel grinding machine capable of increasing economic efficiency.
