Description

Magnesium sheet polishing process system {SYSTEM FOR GRINDING MAGNESIUM PLATE}

The present invention relates to a magnesium plate polishing process system, and more specifically, a polishing process, a desorption process and a hot air drying process on both sides of a magnesium plate going in one direction can be performed in a sequence, and the polishing belt By applying a triaxial structure of three axes rather than two axes of the rotating axis of the axis, the pass line of the magnesium plate and the volume of the polishing process equipment can be minimized, and the polishing belt is supported by supporting the inside of the polishing belt through a plurality of support shafts. It relates to a magnesium plate polishing process system to minimize vibration and shaft vibration of the rotating shaft to rotate.

In general, metal plate materials such as magnesium, aluminum, and stainless steel may be contaminated with foreign substances in the manufacturing process, and when exposed to the outside, the surface may be deteriorated through corrosion, oxidation, etc., and unsuitable for processing.

Therefore, a process for removing foreign substances or contaminants is essential, and for this purpose, the metal plate is polished in a state suitable for processing to remove foreign substances or other contaminants, and the surface is smoothly and neatly processed.

This polishing process is mainly performed by a large area roll grinding using sandpaper (sandpaper). Since the distance between the rotational axes of the two axes for rotating the sandpaper corresponds to 2 m or more, polishing is performed to polish both surfaces of the metal plate. There is a problem that excessive space is required to accommodate the process pass line and the polishing process equipment volume.

In addition, conventionally, as the rotating shaft for rotating the sandpaper at a high speed has a two-axis structure and the distance between the rotating shafts is also 2 m or more, excessive vibration and shaft vibration are generated in the rotating shaft, which means that the abrasive belt rotating at high speed rotates To cause the belt to be pulled out of the center and to one side. Therefore, in the past, a separate oscillation device had to be installed to prevent this.

Accordingly, there is a need for a technique capable of simultaneously polishing both surfaces of the metal plate while minimizing the pass line and equipment volume when polishing the metal plate.

Hereinafter, preferred embodiments are provided to help understanding of the present invention. However, the following examples are only provided to more easily understand the present invention, and the contents of the present invention are not limited by the examples.

1 is a view schematically showing a configuration of a magnesium plate polishing process system 100 according to an embodiment of the present invention, and FIG. 2 is a view more specifically showing the uncoiler 110 shown in FIG. 1. , FIG. 3 is a diagram schematically showing the configuration of the polishing unit 120 shown in FIG. 1.

Referring to FIG. 1, the magnesium plate polishing process system 100 according to an embodiment of the present invention is largely an uncoiler 110, a polishing unit 120, a water removing unit 130, a drying unit 140, and a recoiler. It includes 150.

Referring to FIG. 2, the uncoiler 110 is a device for unwinding and supplying one end portion to a polishing part 120, which will be described later, through a rotation of a motor at a constant speed while the magnesium plate material in the form of a thin plate is wound on a disk disc. to be.

Since the uncoiler 110 may be applied with a device for unwinding a conventional thin metal plate, a detailed description will be omitted.

The polishing unit 120 serves to polish both sides of the magnesium plate material unwound from the uncoiler 110 and proceed in one direction. The polishing unit may include an upper polishing unit 121 for polishing the upper surface of the magnesium plate material, and a lower polishing unit 122 for polishing the lower surface of the magnesium plate material. This will be described in more detail with reference to FIG. 3.

Referring to FIG. 3, the polishing unit 120 is largely configured to include an upper polishing unit 121 and a lower polishing unit 122.

The upper polishing section 121 is again a housing 121a, one or more stay bars 121b, three rotating rollers 121c-1, 121c-2, 121c-3, a rotating motor 121d, and a polishing belt 121e , Auxiliary rotating roller (121f), a surface pressure control device (121g) and height adjustment device (121h).

The housing 121a has a predetermined inner skin, and there are one or more stay bars 121b, three rotating rollers 121c-1, 121c-2, and 121c-3, which will be described later, a polishing belt 121e, and an auxiliary rotating roller. (121f), the surface pressure adjusting device (121g) will have an internal space for receiving.

In particular, an inlet 121a-1 and an outlet 121a-2 for penetrating the magnesium plate are formed in accordance with the progressing direction of the magnesium plate. The magnesium plate is drawn into the housing 121a through the inlet 121a-1, and the magnesium plate is drawn out through the outlet 121a-2 toward the water removal unit 130 to be described later.

On the other hand, the housing 121a has a hexahedral shape of a metal material, but one side is formed to be able to visually observe the inside of the housing 121a from the outside as it is covered with a transparent PC cover member. Therefore, the rotating state of the polishing belt 121e, the polishing state of the magnesium plate material, the progressing state, and the like can be easily observed with the naked eye of the operator outside the housing 121a. In particular, as the cover member is provided with a check window that can be opened and closed in the vertical direction, it is possible to replace the polishing belt 121e or adjust the tension of the rotating roller.

One or more stay bars 121b are installed to protrude in the width direction of the magnesium plate from the inner surface of the housing 121a, which is polished to rotate at a high speed by supporting the inner surface of the polishing belt 121e, which will be described later. By the belt 121e, vibration and vibration of the three rotating rollers 121c-1, 121c-2, and 121c-3 of the three-axis structure are prevented from occurring. At least seven such stay bars 121b are installed.

Meanwhile, the polishing belt 121e polishes the upper surface of the magnesium plate material while rotating at a high speed by the first to third rotating rollers 121c-1, 121c-2, and 121c-3, which are three rotating rollers.

More specifically, three rotating rollers, that is, the first to third rotating rollers 121c-1, 121c-2, and 121c-3 in the direction corresponding to the above-described stay bar 121b on the inner surface of the housing 121a ) Is protruding. At this time, as the first to third rotating rollers 121c-1, 121c-2, and 121c-3 have a triangular structure, the abrasive belt 121e rotates at a high speed in a triangular structure. This will be described in more detail with reference to FIG. 4.

FIG. 4 is a view showing a state in which the tension of the third rotating roller shown in FIG. 3 is adjusted.

3 and 4 together, the first and second rotating rollers 121c-1 and 121c-2 are connected via a hinge on the inner surface of the housing 121a to correspond to the high-speed rotation of the polishing belt 121e. Will rotate. In addition, the third rotating roller 121c-3 is disposed to have a triangular structure with the first and second rotating rollers 121c-1 and 121c-2, and is protruded through the hinge on the inner surface of the housing 121a. It is connected to enable rotation between a pair of guide frames 121j connected to both ends of the guide bar 121i for tension adjustment.

The guide bar 121i for tension adjustment is connected to be rotatable through an inner surface and a hinge of the housing 121a, and a pair of guide frames 121j having a constant length is provided at both end portions of the guide bar 121i for tension adjustment. Connected. At this time, one end portion of the pair of guide frames 121j is connected to the guide bar 121j for tension adjustment, and the third rotation roller 121c-3 is connected to the other end portion.

That is, the third rotating roller 121c-3 is hinged by using the guide bar 121i for tension adjustment as a rotating shaft between the pair of guide frames 121j.

At this time, a center bar 121k is provided at the center of the pair of guide frames 121j, and a cylinder device 121l for pushing or pulling the center bar 121k is provided on the inner surface of the housing 121a. .

One end portion of the cylinder device 121l is hinged to the inner surface of the housing 121a, and the other end portion is connected to the center bar 121k.

Therefore, when the center bar 121k is pushed by the expansion/contraction operation of the cylinder device 121l, the pair of guide frames 121j rotate in a direction away from the cylinder device 121l by using the hinge as a rotation axis. The third rotating roller 121c-3 connected to the distal ends of the pair of guide frames 121j is also pushed out.

In this case, the sizes of the triangular structures of the first to third rotating rollers 121c-1, 121c-2, and 121c-3 are increased, and accordingly, the tension of the abrasive belt 121e increases and becomes taut.

Conversely, when the center bar 121k is pulled by the expansion/contraction operation of the cylinder device 121l, the pair of guide frames 121j rotate in the direction closer to the cylinder device 121l by using the hinge as a rotation axis. Accordingly, the third rotating roller 121c-3 connected to the distal ends of the pair of guide frames 121j is also pulled.

In this case, the sizes of the triangular structures of the first to third rotating rollers 121c-1, 121c-2, and 121c-3 are reduced, and accordingly, the tension of the abrasive belt 121e is reduced and loosened.

On the other hand, the distal end of the third rotating roller (121c-3), that is, a pair of guide frame (121j) of the inner surface of the housing 121a, the distal end of the guide frame (121j) side, the bolt through the rotation A third rotation roller angle adjustment device 121m is provided to adjust a vertical angle, which is a fixed angle between the three rotation rollers 121c-3 and the pair of guide frames 121j.

When the third rotation roller angle adjustment device 121m is finely rotated in one direction (eg, clockwise), one end of the third rotation roller 121c-3 does not maintain a vertical state with the guide frame 121j. Without tilting slightly. In this case, the abrasive belt 121e wrapped in the first to third rotating rollers 121c-1, 121c-2, and 121c-3 is rotated by the third rotating roller 121c-3 by the third rotating roller 121c-3. You will be directed to either side of 3).

That is, this adjustment operation of the third rotating roller angle adjusting device 121m causes the polishing belt 121e to be biased to one side, or the biased polishing belt 121e is opposite to the third rotating roller 121c-3. It may be a means for solving the belt tilt of the abrasive belt 121e, such as being biased in the direction or positioned at the center. This eliminates the need for a conventional oscillation device.

Looking at Figure 4 (b), when the polishing process is performed, the cylinder device 121l does not work, but when the polishing belt 121e needs to be replaced, the center bar 121k is pulled by the cylinder device 121l. When the polishing belt 121e is loosened and the center bar 121k is pushed by the cylinder device 121l, the maximum tension is applied while the polishing belt 121e is pulled.

Returning to FIG. 3 again, the rotation motor 121d is connected to the first rotation roller 121c-1 through a timing belt, and rotates the first rotation roller 121c-1 at high speed through rotation of the timing belt. . At this time, the rotational force of the first rotating roller 121c-1 rotates the second and third rotating rollers 121c-2 and 121c-3 together at a high speed through the polishing belt 121e. The rotating motor 121d may be preferably fixedly installed on the upper side of the housing 121a.

The polishing belt 121e is in the form of a belt-shaped sandpaper surrounding the above-described first to third rotating rollers 121c-1, 121c-2, and 121c-3, and the first to third rotating rollers 121c- 1, 121c-2, 121c-3) is rotated in the direction opposite to the direction of progress of the magnesium plate by the rotational force to polish the upper surface of the magnesium plate.

At this time, since one side of the housing 121a is covered by the cover means made of transparent PC material while being opened, the first to third rotation rollers 121c-1, 121c-2, and 121c-3 are opened by opening the cover means. After removing the abrasive belt 121e, it can be replaced with a new abrasive belt.

Magnesium powder generated from the magnesium plate by the polishing belt 121e may be collected on the floor through the lower portion of the housing 121a.

The auxiliary rotating roller 121f is disposed between the first and second rotating rollers 121c-1 and 121c-2, and serves to push the inner surface of the polishing belt 121e in a direction toward the lower magnesium plate. do.

More specifically, the auxiliary rotating roller 121f is positioned slightly lower than the first and second rotating rollers 121c-1 and 121c-2, so that one side of the polishing belt 121e is first and second. It has a shape slightly protruding downward from the rotating rollers 121c-1 and 121c-2.

Accordingly, the contact force between the polishing belt 121e and the magnesium plate material is further increased.

Surface pressure regulating device (121g) is installed on the inner surface of the housing (121a) and the magnesium plate by pushing the magnesium plate in the direction of the secondary rotating roller (121f) as the position in the vertical direction is adjusted to be close to the auxiliary rotating roller (121fg) It serves to increase the contact force between the polishing belt 121e. This will be described in more detail with reference to FIG. 5.

FIG. 5 is a view more specifically showing the surface pressure adjusting device 121g shown in FIG. 3.

Looking at Figure 5, the surface pressure adjusting device (121g) is largely installed on the inner surface of the housing (121a) and the handle (height adjustment hand) (121g-1), the central axis of the vertical axis through the rotation to the vertical axis through or out And the one end portion is connected through the inner surface and the hinge of the housing 121a, the other end is moved in the vertical direction when the vertical axis is moved, and the surface pressure regulating roller pushing the magnesium plate in the direction of the polishing belt 121e ( 121g-2) and a position indicator to indicate the rotation angle of the handle (121g-1), and the degree to which the surface pressure regulating roller (121g-2) pushes the magnesium plate toward the auxiliary rotating roller (121f) numerically. (121g-3).

At this time, the surface pressure adjusting roller (121g-2) is configured to have a length corresponding to the width direction of the magnesium plate, the vertical axis is raised or lowered in a fine unit through the rotation operation of the handle (121g-1). Therefore, the force by which the surface pressure adjusting roller 121g-2 pushes the magnesium plate material in contact with the polishing belt 121e can be adjusted very precisely.

The position indicator 121g-3 is a device for determining a point in time when the magnesium plate material and the polishing belt 121e are more reliably contacted as the surface pressure regulating roller 121g-2 rises in the vertical direction. Through the system, the exact value of the surface pressure adjusting roller 121g-2 can be displayed.

The height adjusting device 121h serves to adjust the height of each corner of the lower part of the housing 121a in the lower part of the housing 121a. This will be described in more detail with reference to FIG. 6.

6 is a view showing the height adjustment device shown in FIG. 3 in more detail.

Referring to FIG. 6, a seating surface 121h-5 on which the housing 121a is seated is provided on a lower side of the housing 121a, and first to fourth vertical support shafts are respectively provided at each corner of the seating surface 121h-5. (121h-1, 121h-2, 121h-3, 121h-4) are prepared. At this time, a base supporter is provided at each corner of the seating surface 121h-5, and the base supporters are provided on the first to fourth vertical support shafts 121h-1, 121h-2, 121h-3, and 121h-4, respectively. In the fitted state, the first to fourth vertical support shafts 121h-1, 121h-2, 121h-3, and 121h-4 are moved in the vertical direction.

On the lower side of the four base supporters, the first to fourth heights are adjusted in the vertical direction while rotating along the threads formed outside the first to fourth vertical support shafts 121h-1, 121h-2, 121h-3, and 121h-4. Fourth height adjustment gear (chain gear) (121h-6, 121h-7, 121h-8, 121h-9) is provided.

At this time, the first to fourth height adjustment gears (121h-6, 121h-7, 121h-8, 121h-9) are connected to each other through a chain (121h-10), the first vertical support shaft (121h-1) When the first height adjustment gear 121h-6 rotates through rotation of the handle 121h-11 connected to the first height adjustment gear 121h-6 provided in the first height adjustment gear 121h-6 and The second to fourth height adjustment gears 121h-7, 121h-8, and 121h-9, which are connected to each other through the chain 121h-10, all rotate at the same time. Therefore, in this case, the seating surface 121h-5 moves in the vertical direction while forming a horizontal state.

At this time, a chain tension adjusting device 121h-12 for adjusting the tension of the chain 121h-10 is provided on one side of the seating surface 121h-5, and the chain ( When the tension of 121h-10) is loosened, the binding force between the first height adjusting gear 121h-6 and the second to fourth height adjusting gear 121h-7, 121h-8, 121h-9 is removed.

Therefore, in this case, the height adjustment of each of the first to fourth height adjustment gears 121h-6, 121h-7, 121h-8, and 121h-9 is made individually.

That is, when the handle 121h-11 connected to the first height adjusting gear 121h-6 is rotated, the base supporter mounted on the first height adjusting gear 121h-6 and the corresponding seating surface 121h- When only the edge of 5) is raised or lowered, and only the second height adjustment gear 121h-7 is rotated, the base supporter seated on the second height adjustment gear 121h-7 and the corresponding seating surface 121h- Only the edge of 5) rises or falls.

At this time, on the lower side of the second to fourth height adjustment gear (121h-7, 121h-8, 121h-9) to the outside of the second to fourth vertical support shaft (121h-2, 121h-3, 121h-4) A height fixing nut (stopper nut) for fixing the positions of the second to fourth height adjustment gears 121h-7, 121h-8, and 121h-9 while rotating along the formed thread is provided.

Therefore, the first to fourth height adjustment gears 121h-6, 121h-7, 121h-8, and 121h-9 in the state where the chain 121h-10 is loosened through the chain tension adjusting device 121h-12. After adjusting the height of each corner of the seating surface 121h-5 by rotating each, then rotating the height fixing nut to rotate the second to fourth height adjusting gears 121h-7, 121h-8, and 121h-9. It will fix the position.

Meanwhile, in the above description, only the upper abrasive portion 121 has been described. The lower abrasive portion 122 has a lower position of the housing 122a when compared to the upper abrasive portion 121. 2 that the third rotating roller 122c-3 is positioned lower than the rotating rollers 122c-1 and 122c-2, that the polishing belt 122e polishes the lower side of the magnesium plate, and the auxiliary rotating roller 122f ) Is that the inner surface of the polishing belt 122e is supported in the upward direction between the first and second rotating rollers 122c-1 and 122c-2, and the surface pressure adjusting device 122g is the upper side of the housing 122a. Since it is all the same as the description of the upper polishing portion 121 except that the magnesium plate is pushed downward in the fixed state, a detailed description of the lower polishing portion 122 will be omitted.

The water removing unit 130 serves to remove water from the magnesium plate material on which both sides of the polishing process are completed through the above-described polishing unit 120. This will be described in more detail with reference to FIG. 7.

7 is a view more specifically showing the water removal unit 140 shown in FIG.

In the polishing process through the polishing unit 120 described above in FIGS. 3 to 6, a wet polishing method is used to minimize the generation of magnesium powder and heat. Therefore, water remains on both sides of the magnesium plate material on which both sides of the polishing process have been completed. If the residual water is not removed, stains, rust, and corrosion of the magnesium plate material may rapidly progress.

Therefore, the water removing unit 130 continuously absorbs water on both sides of the magnesium plate by rotating the water blocks of PVA material in the form of rings on both sides of the magnesium plate.

The water removal unit 130 may be largely divided into an upper water removal unit and a lower water removal unit.

The water removal unit 130 is largely a pair of pulleys (pulley) that continuously rotates the ring-shaped water block 131, the water block 131 to rotate along the width direction of the upper or lower side of the magnesium plate ( 132), pressurizes the inner surface and the outer surface of the water block 131, and pressurizes and removes the water absorbed by the water block 131, thereby compressing and removing high pressure gas to the outer surface of the water block 131. It may be configured to include a high-pressure gas injection device 134 and the like to remove foreign matter on the water block 131 by spraying.

Referring to FIG. 7, FIG. 7(a) is a view showing an upper water removal portion, and FIG. 7(b) is a view showing a lower water removal portion.

Referring to Figure 7 (a), the elongated band-shaped water block 131 is rotated in one direction by two pulleys 132, wherein the one-sided direction may mean the width direction of the magnesium plate.

For example, in FIG. 7(a), while the water block 131 rotates clockwise, water on the upper surface of the magnesium plate is continuously absorbed, and the water block 131 absorbing water is attached to the compression roller 133. After the water is removed while being compressed, the pulley 132 continuously rotates.

At this time, the high-pressure gas injection device 134 by blowing high-pressure gas to the lower surface of the water block 131 to blow off the magnesium powder or foreign substances on the water block 131.

Looking at Figure 7 (b), the elongated band-shaped water block 131 is rotated in one direction by two pulleys 132, wherein the one-sided direction may mean the width direction of the magnesium plate.

For example, in FIG. 7(b), while the water block 131 rotates in a counterclockwise direction, water on the upper surface of the magnesium plate is continuously absorbed, and the water block 131 absorbing water is compressed roller 133. After the water is removed while being squeezed by, the pulley 132 continues to rotate.

At this time, the high-pressure gas injection device 134 by blowing high-pressure gas to the lower surface of the water block 131 to blow off the magnesium powder or foreign substances on the water block 131.

That is, the moisture of the magnesium plate is rapidly absorbed by the upper water removing portion and the lower water removing portion, and as the moisture is squeezed and removed, it is possible to continuously remove the moisture of the magnesium plate.

The drying unit 140 serves to completely dry both sides of the magnesium plate by applying hot air to both sides of the magnesium plate. If the fine residual water remaining unremoved through the above-described water removal unit 130 may remain, this may be caused by staining, rust, corrosion, etc. of the magnesium plate. Will be removed.

At this time, the drying unit 140 is divided into up and down so as to apply hot air to the upper and lower sides of the magnesium plate, respectively.

The recoiler 150 serves to rewind the magnesium plate, which proceeds in a state in which it is completely dried by the drying unit 140, and at this time, insert a slip sheet between the recoiler 150 and the drying unit 140. An interstitial insertion device is provided.

Therefore, the magnesium plate material is wound by the recoiler 150, and at the same time, the sexagenary cycle is wound together with the magnesium plate material.

At this time, since the recoiler 150 corresponds to the uncoiler 110 described above, detailed description will be omitted.
