Description

Technical Field

[0001] The invention relates to the technical field of polishing wheels, and in particular to a polishing wheel capable of reducing the influence of axial deformation and an implementation method thereof. Background Art

[0002] Rubber and polyurethane binders are used as grinding wheels for glass processing, polishing and glazing. They are elastic and will deform elastically when subjected to force. With the development of high-speed (line speed above 45 m / min) grinding technology, high-speed and efficient polishing has been limited by indicators such as polishing wheel rotation strength, heat resistance, and moderate elasticity, and has not been widely used. At present, it mainly relies on the adaptation research of binder materials, such as improving the strength of the binder and improving the heat resistance of the binder, but the improvement is limited.

[0003] The polishing wheel deforms under the action of centrifugal force in the radial and axial directions. As the speed increases, the deformation amount is positively correlated until it bursts.

[0004] The main working surface of the cup-shaped polishing wheel is the end surface, such as Figure 1 and Figure 2 As shown, the prior art adopts a composite structure of adding a rigid sleeve to the outer circumferential surface, which can play a role in radial direction restraining the outer diameter deformation; after the inner diameter is restrained by the outer diameter of the polishing wheel, the radial deformation is subject to certain constraints, but the axial deformation will become larger, causing the working surface to bulge and lose the normal grinding surface shape. The deformation is characterized by: the bulge height close to the inner diameter of the polishing wheel is greater than the bulge height close to the outer diameter, such as Figure 3 The diagram shown is a schematic diagram of the change in the state of the end face of the working ring when the polishing wheel rotates at high speed. When the polishing wheel is working, the axial protrusion of the inner diameter part is restricted by the grinding surface of the workpiece, thereby increasing the positive pressure of the protrusion on the workpiece, causing increased friction heat, which is prone to burns of the polishing wheel or the workpiece (commonly known as abrasions).

[0005] For thin-tooth spliced ​​polishing wheels, the raised part will increase the circumferential pressure between the teeth, making it more difficult for the thin-tooth teeth to deform circumferentially under force, greatly reducing the water absorption and water flow effects, and significantly reducing the cooling effect, which can easily lead to burns of the polishing wheel or workpiece (commonly known as abrasions). The axial raised deformation also blocks the flow of cooling water from the inner diameter to the outer diameter under the action of centrifugal force, and because the height of the raised part near the inner diameter is higher than the height of the raised part near the outer diameter, the cooling effect on the outer diameter part is reduced. Summary of the invention

[0006] This summary is provided to introduce concepts in a brief form that will be described in detail in the detailed description below. This summary is not intended to identify key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0007] In the first aspect, the present invention discloses a polishing wheel for reducing the influence of axial deformation, comprising a base bottom plate, an outer ring and an abrasive ring, wherein the outer ring and the abrasive ring are both fixedly placed on the base bottom plate, and the outer ring is fixedly sleeved on the abrasive ring, and a blank area along the axial direction of the abrasive ring is provided between the outer diameter and the inner diameter of the abrasive ring; when the abrasive ring is deformed, the abrasive ring releases stress and deformation in the blank area.

[0008] In a second aspect, the present invention discloses a method for realizing a polishing wheel that reduces the influence of axial deformation, comprising:

[0009] supplying water to a polishing wheel that does not include a release zone and idling the polishing wheel at a set speed;

[0010] When the polishing wheel is running idle, the height of the protrusion of the end surface of the polishing wheel is measured along the radial direction of the polishing wheel, and the change of the inner diameter of the polishing wheel is measured at the same time;

[0011] The shape and size of the release area are determined according to the material of the polishing wheel, the height of the end face protrusion of the polishing wheel, and the change in the inner diameter of the polishing wheel. The release area is a blank area set on the inner wall of the polishing wheel along the axial direction of the polishing wheel.

[0012] According to the shape and size of the relief area, a polishing wheel including the relief area is manufactured.

[0013] The beneficial effects of the present invention are as follows: the axial deformation of the polishing wheel is restricted by the grinding surface of the polishing wheel and then released in the circumferential direction of the blank area, thereby preventing the axial protrusion on the inner diameter part of the abrasive ring from generating positive pressure on the workpiece and causing frictional heating when the polishing wheel is working, thereby causing burns to the polishing wheel or the workpiece; at the same time, after the axial deformation of the polishing wheel is released in the circumferential direction of the blank area, the elastic properties of the inner diameter part of the polishing wheel and the rotation strength of the polishing wheel can be maintained; the blank area in the axial direction of the abrasive ring can be used to apply water supply, improve the water flow effect of the polishing wheel, and enhance the cooling effect; in addition, the polishing wheel including the release area can be suitable for high-speed (i.e., linear speed greater than 45 meters / minute) grinding intervals, thereby increasing the processing linear speed of the polishing wheel and improving the polishing efficiency.

[0014] Based on the above technical solution, the present invention can also be improved as follows.

[0015] Furthermore, the abrasive ring includes a plurality of identical segments; the plurality of identical segments are arranged in parallel along the inner wall of the outer ring; one end of the plurality of identical segments is fixedly connected to the outer ring; adjacent segments are connected and adjacent segments form the blank area at the end away from the outer ring.

[0016] The beneficial effect of adopting the above further solution is that the abrasive ring formed by splicing a plurality of segments is more stable.

[0017] Furthermore, the cross-section of the blank area formed by the adjacent segments connected and at the end away from the outer ring is an isosceles triangle; and the blank area is parallel to the axial direction of the abrasive ring.

[0018] The beneficial effects of adopting the above further scheme are: the blank area adopts an isosceles triangle, and the end of the segment forms an isosceles trapezoid, which can improve the strength and deformation rotation strength of the polishing wheel and ensure the polishing strength of the polishing wheel; the blank area is parallel to the axial direction of the abrasive ring, which can ensure the fluidity of the water flow.

[0019] Furthermore, the block is deformed during the grinding process, so that the blank area is reduced, and the maximum width of the blank area is greater than 0 and less than or equal to a first threshold, and the first threshold is less than the width of the block.

[0020] The beneficial effect of adopting the above further solution is to avoid the interaction force generated by the contact and extrusion of the segments in the blank area, thereby affecting the release effect of the axial deformation of the polishing wheel in the circumferential direction of the blank area during operation.

[0021] Furthermore, a plurality of annular first limiting grooves are arranged on the inner wall of the outer ring along its axial direction, and the abrasive ring expands and deforms under the action of centrifugal force to engage with the plurality of first limiting grooves.

[0022] The beneficial effect of adopting the above further solution is that the abrasive ring expands and deforms under the action of centrifugal force and the multiple limit grooves can increase the friction between the abrasive ring and the inner wall of the outer ring, and inhibit the axial displacement of the abrasive ring at high speed.

[0023] Furthermore, the width of the blank area in the radial direction of the abrasive ring is 0.3 to 0.6 times the ring width of the polishing wheel.

[0024] The beneficial effect of adopting the above-mentioned further scheme is that it is conducive to limiting the angle between the boundary of the blank area and the node block within a certain range, limiting the spatial size of the blank area, reducing the extrusion caused by the circumferential deformation of the node block, reducing the cooling performance and causing temperature rise, resulting in burns of the polishing wheel or the workpiece, and at the same time, the extrusion of the node block except the blank area ensures the strength of the polishing wheel.

[0025] Furthermore, the method further comprises:

[0026] Using the polishing wheel including the release area to run at the set speed to simulate polishing of the workpiece;

[0027] In the simulated polishing process of the workpiece, if the release area is closed, the shape and size of the release area are adjusted; otherwise, the release area is not adjusted.

[0028] The beneficial effect of adopting the above-mentioned further scheme is that by adjusting the release area, the release area can be avoided from being closed, and the axial deformation of the polishing wheel can be prevented from being restricted by the grinding surface of the polishing wheel and unable to be completely released in the circumferential direction, resulting in the end of the polishing wheel to bulge in the axial direction again, generating positive pressure on the workpiece, causing friction and heating, resulting in burns of the polishing wheel or the workpiece.

DETAILED DESCRIPTION

[0042] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0043] Embodiment 1:

[0044] like Figure 4 A top view of a polishing wheel that reduces the influence of axial deformation is shown, Figure 5 For a stereogram, Figure 6 for Figure 4 A cross-sectional view of AA in FIG. 1 ; A polishing wheel for reducing the influence of axial deformation, comprising a base bottom plate 1, an outer ring 2 and an abrasive ring 3, wherein the outer ring 2 and the abrasive ring 3 are both fixedly placed on the base bottom plate 1, and the outer ring 2 is fixedly sleeved on the abrasive ring 3, and a blank area H along the axial direction of the abrasive ring 3 is provided between the outer diameter and the inner diameter of the abrasive ring 3; when the abrasive ring 3 is deformed, the abrasive ring 3 releases stress and deformation in the blank area H.

[0045] Among them, the outer ring 2 is a single integral ring made of nylon plastic; the outer ring 2 can protect the abrasive ring 3 with high rotation strength, and can withstand the abrasive ring 3 under the action of grinding force and centrifugal force without breaking, ensuring that the polishing wheel avoids bursting when rotating at high speed. The base bottom plate 1 is provided with a groove corresponding to the outer ring 2, and the lower end of the outer ring 2 is fixed in the groove; the abrasive ring 3 is fixed by the base bottom plate 1 and the outer ring 2, which is conducive to improving the strength of the abrasive ring 3, so that efficient polishing can be achieved when the polishing wheel rotates at high speed.

[0046] Figure 7 It is an enlarged view of the abrasive ring 3 including the blank area H. The axial deformation of the abrasive ring 3 is limited by the grinding surface of the polishing wheel and then released in the circumferential direction of the blank area H, so as to avoid the axial protrusion on the inner diameter part of the abrasive ring 3 generating positive pressure on the workpiece when the polishing wheel is working, causing friction and heating, leading to burns of the polishing wheel or the workpiece; at the same time, the axial deformation of the polishing wheel releases stress in the circumferential direction of the blank area H, which can maintain the elastic properties of the inner diameter part of the polishing wheel and the rotation strength of the polishing wheel; by applying water supply to the blank area H in the axial direction of the abrasive ring 3, the water flow effect of the polishing wheel can be improved, and the cooling effect can be enhanced.

[0047] In addition, by adopting the principle that the axial deformation of the polishing wheel is limited by the grinding surface of the polishing wheel and then the stress is released in the circumferential direction of the blank area, a polishing wheel including a release area is obtained. The polishing wheel including the release area can be applied to a high-speed (i.e., a linear speed higher than 45 m / min) grinding interval. Compared with the prior art that uses a low-medium speed (i.e., a linear speed lower than 25 m / min) grinding interval, the processing linear speed of the polishing wheel is increased, and the application of a high-speed grinding technology is realized. Therefore, the polishing wheel including the release area has the effect of improving the polishing efficiency.

[0048] Embodiment 2:

[0049] like Figure 4 The figure shows a top view of a polishing wheel that reduces the influence of axial deformation. In this embodiment, based on embodiment 1, the abrasive ring 3 is divided into a plurality of identical segments 4, and the plurality of segments 4 are arranged in parallel along the inner wall of the outer ring 2; one end of the plurality of segments 4 is fixedly connected to the outer ring 2, and the end face of the other end forms the inner wall of the abrasive ring 3.

[0050] The cross-section of the end of the segment 4 in the axial direction near the inner side of the abrasive ring 3 is in the shape of a straight line or an arc. The main parts of the segment 4 are connected, and during the grinding process, the main parts of the segment 4 are squeezed to ensure the strength of the polishing wheel. The segment 4 is narrowed at one end near the inner side of the abrasive ring 3, so that the blank area H appears between the segment 4. When the abrasive ring 3 is deformed, the abrasive ring 3 releases stress and deformation in the blank area H.

[0051] Embodiment 3:

[0052] like Figure 4 The top view of a polishing wheel that reduces the influence of axial deformation is shown. In this embodiment, based on the second embodiment, the adjacent segments 4 are connected and the cross-section of the blank area H formed at the end away from the outer ring 2 by the adjacent segments 4 is an isosceles triangle or other shapes such as a circle, an ellipse, a sawtooth, a trapezoid, etc. When the cross-section of the blank area H is an isosceles triangle, the axial deformation of the polishing wheel can release stress more evenly and effectively in the circumferential direction of the blank area H. When the cross-section of the area between the waists of the trapezoid between the adjacent segments 4 is an isosceles triangle, the cross-section of one end of the segment 4 in the axial direction of the abrasive ring 3 is a trapezoid, that is, the blank area H is an isosceles triangle area. The isosceles triangle area is parallel to the axial direction of the abrasive ring 3 in the axial direction of the abrasive ring 3. The segment 4 can be cooled by passing water through the isosceles triangle area.

[0053] like Figure 8 The top view of the polishing wheel in working state is shown. Fig. 9 This is a partial enlarged view of the abrasive ring 3 in working condition. Fig.10It is a partial enlarged view of the abrasive ring 3. When the polishing wheel is working, the end face 5 of the polishing wheel contacts the workpiece, and under the action of centrifugal force, the axial deformation of the polishing wheel is limited by the grinding surface of the workpiece, and the stress is released in the circumferential direction of the isosceles triangle area, and the segment 4 produces elastic deformation in the circumferential direction, and the elastic deformation of the segment 4 in the axial direction is reduced, and the isosceles triangle area becomes smaller.

[0054] Embodiment 4:

[0055] In this embodiment, based on the embodiment 3, the segment 4 is deformed during the grinding process, so that the blank area is reduced, and the width of the blank area is greater than 0 and less than or equal to the first threshold value, wherein the first threshold value is less than the width of the segment 4. The first threshold value is less than the width of a segment 4, and when the cross-section of the blank area along the radial direction of the abrasive ring is of different shapes, the width of the corresponding blank area expresses different meanings, for example, when the cross-section is circular, the width of the blank area is the diameter length of the circle, and when the cross-section is trapezoidal, the width of the blank area is the length of the long bottom side of the trapezoid.

[0056] In this embodiment, when the cross section is an isosceles triangle, Figure 7 As shown in FIG. 1 , the width of the blank area is the length of the base of the isosceles triangle. The segments 4 are deformed during the grinding process, and the distance between the segments 4 is reduced, so that the isosceles triangle area is reduced. Fig. 9 As shown, the width of the base of the isosceles triangle is greater than 0 and less than or equal to a first threshold, wherein the first threshold is less than the width of the segment 4. That is, when the polishing wheel is working, the segment 4 undergoes elastic deformation in the circumferential direction, so that adjacent segments 4 are in an unclosed state after the circumferential deformation occurs, thereby avoiding compression and collision between the ends of adjacent segments 4.

[0057] Furthermore, the main parts of the adjacent segments 4 close to the outer ring 2 are squeezed against each other to ensure the strength of the polishing wheel. The width d of the isosceles triangle area in the inner diameter direction of the abrasive ring 3 is related to the hardness of the segment 4. When the hardness of the segment 4 is large, the deformation amount in the circumferential direction is small, and the smaller width d of the isosceles triangle area in the inner diameter direction of the abrasive ring 3 is selected, and the space of the blank area H is small; when the hardness of the segment 4 is small, the deformation amount in the circumferential direction is large, and the larger width d of the isosceles triangle area in the inner diameter direction of the abrasive ring 3 is selected, and the space of the blank area H is large. Generally, the width d of the isosceles triangle area in the inner diameter direction of the abrasive ring 3 is 0.3 to 0.6 times the width of the abrasive ring 3.

[0058] Embodiment 5:

[0059] In this embodiment, on the basis of the third embodiment, a plurality of annular limiting grooves are arranged on the inner wall of the outer ring along its axial direction, and the abrasive ring expands and deforms under the action of centrifugal force to engage with the plurality of the first grooves. The abrasive ring expands and deforms under the action of centrifugal force to engage with the plurality of limiting grooves, which can increase the friction between the abrasive ring and the inner wall of the outer ring and inhibit the axial displacement of the abrasive ring at high speed.

[0060] Embodiment 6:

[0061] This embodiment provides a method for implementing a polishing wheel that reduces the influence of axial deformation on the basis of the above embodiment 1, which can be used to implement the structure of the polishing wheel in the above embodiment 1. The implementation method includes:

[0062] Water is supplied to the polishing wheel and the polishing wheel is idling at a set speed; the polishing wheel does not include a release area.

[0063] Wherein, the set rotation speed is less than or equal to the maximum rotation speed of the polishing wheel that meets the safe rotation strength.

[0064] When the polishing wheel is running idle, the height of the protrusion of the end surface 5 of the polishing wheel is measured along the radial direction of the polishing wheel, and the change of the inner diameter of the polishing wheel is measured at the same time; Fig.11 The schematic diagram for measuring the height of the protrusion of the end face 5 of the polishing wheel is as follows: first, when the polishing wheel is stationary, the initial position of the end face 5 of the polishing wheel is recorded; then, when the polishing wheel is idling, the target position of the end face 5 of the polishing wheel is recorded, and according to the position change, the height of the protrusion of the end face 5 of the polishing wheel can be represented by h1. The change in the inner diameter of the polishing wheel is measured in the same way.

[0065] The shape and size of the release area are determined according to the material of the polishing wheel, the height of the protrusion of the end face 5 of the polishing wheel, and the change in the inner diameter of the polishing wheel.

[0066] The release zone is a blank area arranged on the inner wall of the polishing wheel along the axial direction of the polishing wheel; the harder the material of the polishing wheel, the smaller the height of the protrusion of the end face 5 of the polishing wheel, the smaller the change in the inner diameter of the polishing wheel, and the smaller the volume of the release zone; the softer the material of the polishing wheel, the larger the height of the protrusion of the end face 5 of the polishing wheel, the larger the change in the inner diameter of the polishing wheel, and the larger the volume of the release zone.

[0067] The shape and size of the release zone are determined as follows: through multiple tests, the shape and size of the release zone corresponding to different polishing wheel materials, different settings of the polishing wheel rotation speed, and different types of workpieces can be obtained. When the polishing wheel is working, the end face 5 of the polishing wheel contacts the workpiece. Under the action of centrifugal force, the axial deformation of the polishing wheel is limited by the grinding surface of the workpiece and then released in the circumferential direction of the release zone. The space in the blank area is reduced, so that the height of the protrusion of the end face 5 of the polishing wheel is reduced, and the blank area is not closed. According to the shape and size of the release zone, a polishing wheel including the release zone is manufactured. Among them, except for the release zone, the rest of the components of the polishing wheel including the release zone are the same as those of the polishing wheel without the release zone. The specific structure of the polishing wheel including the release zone can refer to the polishing wheel described in the previous embodiment, which will not be repeated here.

[0068] Optionally, according to the shape and size of the release area, one feasible way to manufacture a polishing wheel including a release area is as follows: according to the shape and size of the release area, by cutting and other processing the inner diameter portion of the polishing wheel that does not include the release area, a release area is formed on the inner diameter of the polishing wheel that does not include the release area, thereby obtaining a polishing wheel including a release area.

[0069] During the polishing process of the workpiece, the height of the protrusion of the end face 5 of the polishing wheel and the change amount of the inner diameter of the polishing wheel are different due to the different materials of the polishing wheel, the rotation speed of the polishing wheel and the type of the workpiece. Therefore, in the actual processing process, it is necessary to set the rotation speed of different polishing wheels according to the type of the workpiece, and select the polishing wheel with the material of the polishing wheel, the shape and size of the release area.

[0070] Embodiment 7:

[0071] In this embodiment, based on Embodiment 6, the method further includes:

[0072] The polishing wheel including the release area is used to run at a set speed to simulate polishing of the workpiece; wherein the set speed is less than or equal to the maximum speed of the polishing wheel that meets the safety rotation strength;

[0073] In the simulated polishing process of the workpiece, if the release area is closed, the shape and size of the release area are adjusted; otherwise, the release area is not adjusted.

[0074] The polishing wheel comprising the release area is manufactured and operated at a set speed to simulate the polishing of a workpiece. According to whether the blank area is closed, it is determined whether the polishing wheel comprising the release area needs to be adjusted. If the blank area is closed, the shape and size of the release area are adjusted. Otherwise, there is no need to adjust the polishing wheel comprising the release area.

[0075] Among them, the closure of the blank area indicates that the deformation of the polishing wheel in the circumferential direction is equal to the volume of the blank area. When the blank area is closed, the deformation of the polishing wheel in the circumferential direction is hindered, and the axial deformation of the polishing wheel cannot be completely released in the circumferential direction after being restricted by the grinding surface of the polishing wheel. The end of the polishing wheel will bulge again in the axial direction, generating positive pressure on the workpiece, causing frictional heating, and causing burns to the polishing wheel or the workpiece. Therefore, the closure of the blank area should be avoided, and the shape and size of the release area should be adjusted.
