Description

Compressive force-identificable polishing pad for surface glassing}

The present invention relates to a polishing pad for surface gloss that can confirm the pressing force, and more particularly, it is possible to easily check the pressing force applied from the polishing machine by using the self-strain of the pad to facilitate the polishing operation. The present invention relates to a polishing pad for surface gloss capable of confirming a pressing force.

In general, vehicles are exposed to various environments as the seasons change over the four seasons. Exposure to such an environment causes damage to the paint applied to the surface of the vehicle. As a result, the paint of the vehicle is damaged and the beauty of the exterior disappears and the value of the vehicle is reduced.

The reasons for the damage on the painted surface of the vehicle are largely due to: 1) chemical corrosion caused by acidic substances (acid rain, atmospheric gas, ozone, etc.), 2) damage of paint surface caused by strong ultraviolet rays, and 3) soil and dust, and various dust and yellow dust. The influence may include scratching of the gloss surface.

Of course, such damage is caused by a combination of causes rather than one. Therefore, the surface gloss of such a damaged paint is polished as a surface gloss work if a certain time or scratches occur.

The polishing operation uses a polishing machine. A polishing machine is a kind of electric motor that provides rotational force. Then, the polishing machine is equipped with a polishing pad for glossing using the rotational force on the vehicle surface or the like.

This conventional polishing operation applies an abrasive to a surface to be polished and then operates a polishing machine to cause the polishing pad to polish the painted surface by means of a polishing pad.

However, the conventional polishing operation has the following disadvantages.

1) The pressure applied to the polishing machine, that is, the pressure applied between the polishing surface and the polishing pad, depends on the particle size of the abrasive. The difference in the pressing force is not a skilled worker for a long time can not apply a constant pressing force during the polishing operation, the polishing surface is not properly polished, or even if the polished surface is a cause of damage to the polishing surface.

2) If the worker using the polishing machine is not skilled in the work, the work is inefficient because the polished surface is not evenly polished and the work must be repeated again.

3) Depending on the type of abrasive, different polling pads should be attached and used. It takes a lot of time to remove the polling pads from the polling machine and to attach other polling pads.

The present invention has been devised in view of this point, and the polishing pad is provided with a pressing force display unit so that the polishing pad can be applied by its predetermined strain using its own strain rate. The purpose of the present invention is to provide a polishing pad for surface gloss that can be applied to confirm the pressing force, which can improve the efficiency of gloss work as well as to facilitate the gloss work regardless of skill level.

In addition, the present invention is configured so that only the pad can be replaced from the polishing machine, it is easy to replace when replacing different polishing pads according to the type of abrasive, as well as polishing for surface gloss which can confirm the pressure to improve the work efficiency The purpose is to provide a pad.

According to an aspect of the present invention, there is provided a polishing pad for surface gloss according to the present invention, wherein a Velcro fastener is provided on an upper surface thereof, and a plate-like polishing pad body having a predetermined thickness; And a back pad mounted on the polishing machine having a diameter smaller than the diameter of the polishing pad body, and having a velcro fastener on the bottom thereof so that the Velcro fastener is detachably mounted on the Velcro fastener. The main body is further provided with a pressing force display unit for visually confirming that the deformation of the pressing force applied by the polishing machine by the strength of the predetermined pressing force by using the self-deformation, the pressing force display unit of the polishing pad body It is characterized in that the slope or step surface formed between the edge and the edge of the back pad.

The pressing force display part is characterized in that the circular strip of the color is different from the polishing pad body formed between the edge of the back pad and the upper edge of the polishing pad body. The pressing force display section displays one pressing force among 5 ± 0.5 kg / cm 2, 6 ± 1 kg / cm 2 and 8 ± 1 kg / cm 2, depending on the type of abrasive. Finally, the pressing force display portion is formed on the upper surface of the polishing pad body partitioned by the identification groove formed in the shape of a circular band having an inner diameter of the back pad, and has a circular band shape at equal intervals inside the identification groove. A plurality of deformation grooves are formed.

According to the present invention has the following effects.

1) The operator can easily check the optimum pressing force to be applied to the polishing pad according to the type of abrasive during polishing operation.

2) The polishing surface can be pressurized to the appropriate pressure necessary for polishing, so that the surface gloss effect can be enhanced to the best state.

3) Regardless of the skill of the operator using the polishing machine, anyone can easily and easily polish the polishing machine by using the polishing machine.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

( First embodiment )

1 is a perspective view for explaining the configuration of a first embodiment of a surface polishing polishing pad according to the present invention, Figures 2a and 2b is a side view schematically showing the operating state of the polishing pad according to the present invention. . Here, reference numeral "M" denotes a conventional polishing machine.

The polishing pad 1000 according to the present invention includes a back pad 200 provided with a threaded portion 220 so that the polishing pad 1000 can be mounted on the polishing machine M, and is mounted on the bottom surface of the back pad 200 to determine whether the pressing force is appropriate. It is configured to include a polishing pad body 100 provided with a pressing force display unit 120 to check. Here, the polishing pad body 100 generally means a polishing pad used in the polishing machine (M). In addition, both sides of the polishing pad body 100 and the back pad 200 are provided with velcro fasteners 110 and 210 that are detachable from each other on both sides facing each other.

Hereinafter, with reference to Figures 1, 2A and 2B will be described in more detail.

The polishing pad body 100 is formed in a disk shape having a predetermined thickness and is formed to have a diameter slightly larger than that of the back pad 200. In addition, the polishing pad main body 100 is provided with a pressing force display unit 120 for checking whether the pressing force applied from the polishing machine M is a proper pressure by its elasticity.

The pressing force display unit 120 is formed by cutting the edge of the polishing pad body 100. At this time, the pressing force display unit 120 is formed in the form of a slope as shown in FIG. The angle formed by the slope is determined in consideration of the self strain of the polishing pad body 100 and the strength of the pressing force applied from the polishing machine M. FIG.

That is, in the polishing pad body 100, as in FIG. 2A, when no external force is applied from the polishing machine M, the pressing force display unit 120 having a slope shape maintains the original length H. However, as shown in FIG. 2B, when pressure is applied to the polishing surface M against the polishing pad body 100, the pressing force display unit 120 is deformed together with the polishing pad body 100. At this time, the pressing force display unit 120 is contracted by itself, while being pressed into the polishing pad body 100 to penetrate into the original length (H) is reduced to have a modified length (h) as shown in Figure 2b. Of course, the deformation amount of the pressing force display unit 120 is a pressing pad display unit 100 formed in a slope when the pressure applied by the polishing machine (M), for example 5 ± 0.5 kg / ㎠ The inclination angle is measured in advance so as to be substantially horizontal with the upper surface of the).

In addition, the pressing force display unit 120 may be formed as a slope as described above, but may also be formed as a stepped or inverted surface as shown in FIGS. 3A and 3B. 3A is a partially enlarged view showing an example in which the pressing force display part 120 'is formed in a stepped shape, and the pressing force display part 120' is formed in a disc shape having a predetermined thickness. In this case, the diameter of the pressing force display portion 120 'is preferably the same as the diameter of the back pad 200, so that the pressing force can be applied to the entire pressing force display portion 120'. 3B is a partially enlarged view showing an example in which the pressing force display portion 120 ″ is formed in the form of the inverted surface, and the pressing force display portion 120 ″ is formed in a shape opposite to the above-described slope. In the case of such a step, it is determined as the strength of the preset pressing force until the step is almost disappeared, and in the case of the back surface, when the back pad 200 is almost in contact with the polishing pad body 100.

The pressing force display unit 120, 120 ', 120 "is also a material of the polishing pad body 100 and the pressure applied at this time according to the type of abrasive used, and the strength of the material and the pressing force according to [Table 1] below The deformation amount of the pressing force display portion 120, 120 ', 120 "is determined according to the above.

Type of polishing pad

Particle Size of Abrasive
Optimal pressing force
Polishing Pads for Rough Compounds

800 ~ 200 mesh
8 ± 1㎏ / ㎠
Polishing pad body for intermediate roughness

200 ~ 3000 mesh
6 ± 1㎏ / ㎠
Polishing pad body for fine roughness

3000-4500 mesh
5 ± 0.5㎏ / ㎠
Here, the optimal pressing force means a pressing force in a range in which the worker presses the polishing pad main body 100 to press the polishing pad properly to increase the gloss effect. Of course, it is also possible to ignore this pressing force during the polishing work and to work beyond the optimum pressing force.
The polishing pad main body 100 according to the present invention has, for example, an optimum pressing force of 8 ± 1 kg / cm 2 in the case of a rough compound. This means that when the pressing force display portion 120 provided in the polishing pad body 100 is applied with a pressing force (8 ± 1 kg / cm 2) in this range, the length deformed as 2b from the original length H of FIG. 2A ( h) will cause deformation. As a result, in the case of using a rough compound, the polishing pad main body 100 is pressurized in the range of the pressing force (8 ± 1kg / cm 2) to perform surface gloss work. At this time, the pressing force display unit 120 causes deformation in proportion to the application of the pressure, and it is determined whether the optimum pressing force is applied while the operator visually checks the deformation.
Therefore, when the worker presses the polishing pad main body 100, the pressure is no longer pressed because it is determined that the optimum pressing force is applied when it is deformed by the deformed length h while visually confirming the deformation of the pressing force display unit 120. It will be polished while maintaining the state without doing it.

( Second embodiment )

Figure 4a is a perspective view of the free state for explaining the configuration of the second embodiment of the surface polishing polishing pad according to the present invention, Figure 4b shows the operating state of the second embodiment of the surface polishing polishing pad according to the present invention For the sake of brevity, a side view schematically showing a state in which an appropriate pressure is applied. Here, only the difference compared with the first embodiment will be described.

According to the present invention, the pressing force display portion 120a can be manufactured in the shape of a strip having a color. The polishing pad 1000b according to the second embodiment of the present invention has a strip-shaped pressing force display unit 120a positioned between the upper surface of the disk-shaped pad body 100 having a predetermined thickness and the back pad 200. ).

At this time, the pressing force display portion 120a has a circular shape centering on the rotational center axis line of the back pad 200 and is formed to have a predetermined width W, for example, 8 to 14 mm. It is preferable that the pressing force display portion 120a be formed as close to the edge end of the back pad 200 as possible. This is to form a pressing force display portion 120a in the most deformation portion of the pressing force display portion 120a and the polishing pad body 100 with respect to the pressing force change, so that the change in the strength of the pressing force can be easily checked with the naked eye.

When the polishing pad main body 100 of the second embodiment is not pressurized by the back pad 200, as shown in FIG. 4A, the pressing force display unit 120a has a predetermined width W, for example, 8 to 14 mm. Has a width. However, as shown in FIG. 4B, when the polishing pad main body 100 is pressed by the back pad 200, the most deformed portion of the back pad 200 is pushed inward. Accordingly, the width W of the original width W of the pressing force display portion 120a changes according to the strength of the pressing force. The width w changed to an appropriate pressing force is, for example, 1 to 4 mm to be significantly reduced by 1/14 to 1/4 of the original width W so that the naked eye can easily check.

On the other hand, the pressing force display portion 120a has a color different from that of the polishing pad body 100 so that the operator can easily determine the strength of the pressing force without causing the pressing force display portion 120a to be confused with the polishing pad body 100. It is preferable.

( Third embodiment )

5 is a side view for explaining the configuration of the third embodiment of the polishing pad for surface gloss according to the present invention.

The polishing pad 1000a according to the third embodiment is integrally formed by bonding the back pad 200 to the back pad 200 by separating the pressing force display unit 120b from the polishing pad body 100. In addition, the pressing force display unit 120b is configured to be detachable from the polishing pad body 100 using the Velcro fastener 130.

That is, the pressing force display portion 120b separated from the polishing pad body 100 fixes the upper surface integrally to the back pad 200, and the polishing pad body 100 and the pressing force display portion 120b are detachable on both sides facing each other. It is configured to. In this case, the pressing force display unit 120b and the back pad 200 may be configured to be detachable with the Velcro fastener 130. Here, the pressing force display unit 120b is described as being separated from the polishing pad body 100, but the pressing pad display unit 100b is manufactured separately from the polishing pad body 100, and then the polishing pad body 100 is Velcro. The fastener 130 may be mounted.

Accordingly, even if the polishing pad body 100 is worn out due to wear or the like, only the polishing pad body 100 may be replaced by separating the pressing force display unit 120b which is relatively recyclable.

The polishing pad 1000a may be advantageously used when the polishing machine M uses many of the same abrasive particles. That is, when the abrasive particles are mainly used in the coarse compound of 800-2000 mesh, the polishing pad main body 100 can be easily replaced.

( Fourth embodiment )

6A and 6B are side views for showing a state before and after the operation of the polishing pad according to the fourth embodiment. Here, the detailed description of the same configuration as in the other embodiments described above will be omitted.

The polishing pad 1000c according to the fourth embodiment includes a polishing pad body 100 and a back pad 200 configured to be attached and detached with Velcro fasteners 110 and 210 on the surfaces facing each other, and in particular, the polishing pad. The pressing force display part 120c is further formed on the upper surface of the main body 100.

The pressing force display portion 120c is formed on the upper surface of the polishing pad body 100 by an identification groove 121 formed in a circular band shape having an inner diameter of the back pad 200. That is, the pressing force display part 120c is comprised by the upper surface of the polishing pad main body 100 corresponding to the inside of this identification groove 121. At this time, as described above, the pressing force display unit 120c determines the depth in consideration of the deformation amount when the proper pressure is applied. In addition, in the preferred embodiment of the present invention, in order to more easily check the pressing force, the upper surface of the back pad 200 may be manufactured by manufacturing the back pad 200 to a thickness substantially equal to the depth of the pressing force display part 120c. It is preferable to make it possible to confirm that the pressing was performed at an appropriate pressure by pressing the adhesive pad to almost the upper surface of the polishing pad body 100. The identification groove 121 is formed in the groove-shaped cross-section, so that the operator can easily identify the deformation of the pressing force display portion 120c with the naked eye.

In addition, it is preferable that a plurality of deformation grooves 122 are further formed in the pressing force display unit 120c in a circular band shape inside the identification groove 121. This is because the formation of the identification groove 121, when the pressing force display portion 120c in the form of a disc, when the material of the high strength of the pressing force, that is, the material of the polishing pad body 100 is a hard material so as not to be deformed well do. Thus, the polishing pad body 100 is to form a plurality of deformation grooves 122 at equal intervals inside the identification groove 121 so that deformation can be made well by the pressing force. The deformed grove 122 is formed to be coaxial with the identification grove 121, so that the pressure applied is evenly distributed evenly and the deformation occurs. In addition, the deformation groove 122 is not limited to being formed in a circular band shape, and may be formed in any form as long as it forms a symmetrical shape such as a radial shape.

As described above, the polishing pad 1000c may be mounted on the bottom surface of the back pad 200 mounted on the polishing machine M through the screw portion 220 using the Velcro fasteners 110 and 210. In this state, the polishing pad 1000c is brought into close contact with the coating surface S, that is, in a state where no pressing force is applied, the pressing force display portion 120c is in a state without any deformation. That is, the entire thickness D of the back pad 200 is exposed to the outside as it is.

When a pressure is applied to the back pad 200 in contact with the painting surface S through the polishing machine M for the painting work, as shown in FIG. 6B, the back pad 200 controls the pressing force display unit 120c. While pressing, it is pressed into the polishing pad body 100. Accordingly, if the thickness d of the back pad 200 exposed to the outside of the polishing pad body 100 becomes thinner with the naked eye, the back pad 200 is coplanar with the polishing pad body 100. It is judged that the pressurized to the desired appropriate pressure. At this time, the change in thickness (D, d) is preferably changed to at least 1/5 ~ 1/10 so that the operator can easily confirm.

As described above, according to the present invention, the pressing force display unit 120, 120 ', 120 ", 120a, 120b, or the like may be used to determine whether the pressing force is applied by a predetermined pressure by the strength of the pressing force applied to the polishing pad body 100. By constructing 120c), it is possible to apply an appropriate pressing force according to the particle size of the abrasive, thereby increasing the work efficiency to give surface gloss, and also to facilitate polishing work even by an inexperienced worker.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
