Elastic grinding element and split-off grinding wheel

Abstract

This invention relates to an elastic grinding component and a composite grinding wheel, belonging to the field of grinding wheels. It includes: an elastic substrate, an electroplated substrate, and an electroplated grinding layer. The electroplated grinding layer is coated on one sidewall of the electroplated substrate, and the other side of the electroplated substrate is fixed to the sidewall of one end of the elastic substrate. The elastic substrate is made of stainless steel spring steel, and the electroplated substrate is made of manganese steel spring steel. This invention places the electroplated substrate between the electroplated grinding layer and the elastic substrate, and selects manganese steel spring steel as the electroplated substrate. This selection leverages the material's reliable hard backing, while also considering the ease of obtaining and ensuring bonding strength in the pre-treatment process of electroplating. Simultaneously, stainless steel spring steel is chosen as the elastic substrate, taking advantage of stainless steel's corrosion resistance, high fatigue strength under cooling water conditions, and relative insensitivity to stress concentration, while also being suitable for cold working for mechanical fixation of the electroplated substrate.

Description

Technical Field

[0001] This invention relates to the field of grinding wheels, and more particularly to an elastic grinding element and a composite grinding wheel. Background Technology

[0002] A flexible grinding wheel is formed by winding multiple flexible grinding components into a ring and fixing them to a grinding wheel base through a bonding process. The flexible grinding components include a base plate and a diamond grinding layer. The base plate includes a mounting section, a flexible transition section, and a working section. The mounting section is fixed at one end of the flexible transition section and is fixedly connected to the grinding wheel base. The working section is fixed at the other end of the flexible transition section. The diamond grinding layer is bonded to the circumferential sidewall of the working section. The base plate is made of spring steel (such as 65Mn, 301 stainless steel, etc.).

[0003] When using electroplated (nickel-bonded, the same below) elastic grinding parts in a composite grinding wheel, the following problems arise in the selection of substrate materials: When choosing manganese steel such as 65Mn, it serves as a good hard backing (which is beneficial to improving the utilization rate of diamond), but it is very prone to breakage due to stress concentration at the contact point between the support between two adjacent elastic grinding parts and the elastic transition section of the elastic grinding parts; when choosing 301 stainless steel, its hardness is too low and the pretreatment for electroplating is very complicated and the bonding force is difficult to control, which easily leads to delamination of the diamond grinding layer; while choosing medium and low carbon steel such as 45 steel, although the pretreatment for electroplating is relatively simple and reliable, the material elasticity is insufficient and it is prone to breakage due to fatigue sources caused by rust.

[0004] Therefore, existing elastic grinding components cannot simultaneously provide the substrate with reliable hard backing, high fatigue strength, and corrosion resistance. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an elastic grinding part and a composite grinding wheel to solve the above-mentioned problem.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an elastic grinding part, comprising: an elastic substrate, an electroplated sheet substrate, and an electroplated grinding layer, wherein the electroplated grinding layer is plated on one side wall of the electroplated sheet substrate, and the other side of the electroplated sheet substrate is fixed to the side wall of one end of the elastic substrate, wherein the elastic substrate is made of stainless steel spring steel material, and the electroplated sheet substrate is made of manganese steel spring steel material.

[0007] The beneficial effects of this invention are as follows: Compared with the prior art, which directly fixes the electroplated grinding layer to the sidewall of the elastic substrate, this invention sets an electroplated sheet substrate between the electroplated grinding layer and the elastic substrate, and selects manganese steel spring steel as the electroplated sheet substrate to form a composite structure elastic grinding part. This not only takes advantage of the material's reliable hard backing, but also considers the characteristics of the material's pretreatment process for electroplating and the relatively easy-to-ensure bonding force. This ensures the convenience of pretreatment when the electroplated grinding layer is fixed on the electroplated sheet substrate and the stable support during operation, reducing the possibility of the electroplated grinding layer falling off. At the same time, stainless steel spring steel is selected as the elastic substrate, which takes advantage of the corrosion resistance of stainless steel, its high fatigue strength in the working environment with applied cooling water, and its relatively low sensitivity to stress concentration. It also takes into account the suitability for cold working for mechanical fixation of the electroplated sheet substrate, thus ensuring that the elastic grinding part is not prone to breakage and has good elastic properties.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the elastic substrate includes: an installation section, an elastic transition section, and a working section. The installation section and the working section are respectively fixedly disposed at both ends of the elastic transition section. An anti-flying structure is provided on the working section. The other side of the electroplated sheet substrate is fixed to the side wall of the working section through the anti-flying structure.

[0010] The beneficial effect of adopting the above-mentioned further solution is that it facilitates elastic grinding between the elastic matrix and the workpiece through the elastic transition section, thereby reducing the occurrence of edge breakage.

[0011] Furthermore, the anti-flying structure includes a bending plate and a limiting baffle. The two bending plates are respectively bent and disposed on both sides of the working section, used to press the two sides of the electroplated sheet substrate tightly after bending. The two limiting baffles are respectively fixedly installed on both sides of the working section. The distance between the two limiting baffles is adapted to the width of the electroplated sheet substrate, used to limit the electroplated sheet substrate between the two limiting baffles. The bending plate and the limiting baffles are spaced apart.

[0012] The beneficial effects of adopting the above-mentioned further solutions are that the bending plate and the limiting baffle help prevent the electroplated sheet substrate from shifting or detaching from the elastic substrate under force.

[0013] Furthermore, the anti-flying structure includes multiple spaced-apart overflow holes, and the other side of the electroplated sheet substrate is bonded and fixed to the side wall of the working section. The overflow holes are through holes provided on the working section.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the bonding is suitable for diamond grinding wheels that are fine or high-precision, and the overflow hole helps to make the connection between the electroplated sheet substrate and the working section more stable after the glue is fully applied, thereby draining excess glue. In addition, it also helps to accommodate some glue, further enhancing the connection between the electroplated sheet substrate and the working section.

[0015] Furthermore, the anti-flying structure includes a welding layer, which is disposed between the electroplated sheet substrate and the working section, for welding and fixing the electroplated sheet substrate to the side wall of the working section.

[0016] The beneficial effects of adopting the above-mentioned further solutions are: welding is suitable for coarse or fine grinding diamond wheels, and the weld layer helps to improve the stability of the connection between the electroplated substrate and the working section.

[0017] Furthermore, the anti-flying structure includes a thermoplastic curing block manufactured by an insert molding integrated process, the thermoplastic curing block being circumferentially wrapped around the electroplated sheet substrate and the working section.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the thermoplastic curing block is conducive to fixing the electroplated sheet substrate and the elastic substrate in the circumferential direction.

[0019] Furthermore, a second limiting hole is provided on the side wall of the working section away from the elastic transition section, and a first limiting hole is provided on the side wall of the electroplated sheet substrate. The first limiting hole and the second limiting hole are overlapped. The thermoplastic curing block is provided with a limiting insert and an installation groove inside. The electroplated sheet substrate and the working section are adapted to be installed in the installation groove, and the limiting insert is adapted to be inserted into the first limiting hole and the second limiting hole.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the limiting plug is adapted to be inserted into the first limiting hole and the second limiting hole, which is conducive to fixing the electroplated sheet substrate and the working section in the mounting groove.

[0021] Furthermore, limiting plates are fixedly provided on both sides of the working section, and limiting grooves are provided on both sides inside the thermoplastic curing block. The two limiting plates are respectively adapted to be inserted into the two limiting grooves.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the limiting plate combined with the limiting groove helps to improve the connection stability between the elastic substrate, the electroplated sheet substrate and the electroplated grinding layer.

[0023] Furthermore, a second limiting tooth is fixedly provided on both sides of the working section, and a first limiting tooth is fixedly provided on both sides of the electroplated sheet substrate. The first limiting tooth and the second limiting tooth are overlapped. A third limiting tooth is provided on both sides inside the thermoplastic curing block. The first limiting tooth and the second limiting tooth are connected to the third limiting tooth in a concave-convex fit.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the first and second limiting teeth are connected with the third limiting tooth through a concave-convex fit, which helps to improve the stability of the connection between the elastic matrix, the electroplated sheet matrix and the thermoplastic curing block.

[0025] A composite grinding wheel includes the aforementioned elastic grinding elements, support elements, and grinding wheel base. A plurality of the elastic grinding elements and a plurality of the support elements alternately abut against each other circumferentially to form a grinding ring. The grinding ring is fixedly installed on the end face of the grinding wheel base to form a cup-shaped grinding wheel, or fixedly installed on the outer circumferential surface of the grinding wheel base to form a peripheral grinding wheel.

[0026] The beneficial effects of adopting the above-mentioned further solution are: multiple elastic grinding parts and multiple support parts alternately abut against each other in the circumferential direction to form a grinding ring and are fixedly installed on the grinding wheel base, which can form a grinding wheel with elastic grinding characteristics, and can greatly replace grinding wheel products of traditional powder metallurgy process and resin bonded process.

[0029] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0030] Example 1.

[0031] like Figures 2 to 14 As shown, this embodiment provides an elastic grinding component 1, which includes: an elastic substrate 11, an electroplated sheet substrate 12, and an electroplated grinding layer 13. The electroplated grinding layer 13 is plated on one side wall of the electroplated sheet substrate 12, and the other side of the electroplated sheet substrate 12 is fixed to the side wall of one end of the elastic substrate 11. The elastic substrate 11 is made of stainless steel spring steel, and the electroplated sheet substrate 12 is made of manganese steel spring steel.

[0032] It should be noted that: Figure 1 and Figure 2 As shown, the elastic grinding wheel described in the background art is prone to breakage of the elastic grinding wheel due to stress concentration at the contact point between the support member 2 between two adjacent elastic grinding parts 1 and the elastic transition section 112 of the elastic grinding part 1. The diamond grinding layer described in the background art is equivalent to the electroplated grinding layer 13 in this application. The electroplated grinding layer 13 includes a plurality of diamond particles 131 and a binder 132. The plurality of diamond particles 131 are fixedly disposed in a single layer on one side wall of the electroplated substrate 12 by the binder 132. If multiple elastic grinding parts 1 and multiple support parts 2 alternately abut against each other in the circumferential direction to form a grinding ring, then "single layer" means that a single layer is set along the circumference of the grinding ring.

[0033] The beneficial effects of this embodiment are as follows: Compared with the prior art, which directly fixes the electroplated grinding layer to the sidewall of the elastic substrate, the present invention sets an electroplated sheet substrate between the electroplated grinding layer and the elastic substrate, and selects manganese steel spring steel as the electroplated sheet substrate to form a composite structure elastic grinding part. This not only takes advantage of the material's characteristics as a reliable hard backing, but also takes into account the characteristics of the material's pretreatment process for electroplating and the relatively easy-to-ensure bonding force. This ensures the convenience of pretreatment when the electroplated grinding layer is fixed on the electroplated sheet substrate and the stable support during operation, reducing the possibility of the electroplated grinding layer falling off. At the same time, stainless steel spring steel is selected as the elastic substrate, which takes advantage of the corrosion resistance of stainless steel, its high fatigue strength in the working environment with applied cooling water, and its relatively low sensitivity to stress concentration. It also takes into account the suitability for cold working for mechanical fixation of the electroplated sheet substrate, thus ensuring that the elastic grinding part is not easy to break and has good elastic properties.

[0034] Preferred, such as Figure 3 As shown, the elastic substrate 11 includes: an installation section 111, an elastic transition section 112, and a working section 113. The installation section 111 and the working section 113 are respectively fixedly disposed at both ends of the elastic transition section 112. An anti-flying structure is provided on the working section 113. The other side of the electroplated sheet substrate 12 is fixed to the side wall of the working section 113 through the anti-flying structure.

[0035] It should be noted that in this embodiment, if multiple elastic grinding elements 1 and multiple support elements 2 alternately abut against each other circumferentially to form a grinding ring, and cooperate with the grinding wheel base 3 to form a cup-shaped grinding wheel, then the mounting section 111 and the working section 113 are respectively fixedly disposed at both ends of the elastic transition section 112 in the axial direction; if multiple elastic grinding elements 1 and multiple support elements 2 alternately abut against each other circumferentially to form a grinding ring, and cooperate with the grinding wheel base 3 to form a peripheral grinding wheel, then the mounting section 111 and the working section 113 are respectively fixedly disposed at both ends of the elastic transition section 112 in the radial direction. The axial and radial directions are determined based on the grinding ring, and the determination of the axial, radial, and circumferential directions in the following text is also based on the grinding ring.

[0036] The advantages of adopting the above preferred scheme are: it facilitates elastic grinding between the elastic matrix and the workpiece through the elastic transition section, reducing the occurrence of edge breakage.

[0037] Example 2.

[0038] like Figure 4 and Figure 5 As shown, based on Embodiment 1, the anti-flying structure includes a bending plate 1131 and a limiting baffle 1132. The two bending plates 1131 are respectively bent and disposed on both sides of the working section 113, for pressing the two sides of the electroplated sheet substrate 12 after bending. The two limiting baffles 1132 are respectively fixedly installed on both sides of the working section 113. The distance between the two limiting baffles 1132 is adapted to the width of the electroplated sheet substrate 12, for limiting the electroplated sheet substrate 12 between the two limiting baffles 1132. The bending plate 1131 and the limiting baffle 1132 are spaced apart.

[0039] It should be noted that in this embodiment, if multiple elastic grinding parts 1 and multiple support parts 2 alternately abut against each other in the circumferential direction to form a grinding ring, and cooperate with the grinding wheel base 3 to form a cup-shaped grinding wheel, then the two bending plates 1131 are arranged on both sides of the working section 113 in the radial direction to press the two sides of the electroplated sheet base 12 in the radial direction, and the two limiting baffles 1132 are fixedly installed on both sides of the working section 113 in the radial direction. The distance between the two limiting baffles 1132 is adapted to the radial width of the electroplated sheet base 12, and the bending plates 1131 and the limiting baffles 1132 are axially spaced apart. If multiple elastic grinding parts 1 and multiple support parts 2 alternately abut against each other circumferentially to form a grinding ring, and cooperate with the grinding wheel base 3 to form a peripheral grinding wheel, then the two bending plates 1131 are arranged on both sides of the working section 113 axially to press the two sides of the electroplated sheet base 12 axially. The two limiting baffles 1132 are fixedly installed on both sides of the working section 113 axially. The distance between the two limiting baffles 1132 is adapted to the axial width of the electroplated sheet base 12. The bending plates 1131 and the limiting baffles 1132 are arranged radially at intervals.

[0040] The advantages of adopting the above preferred solution are: the bending plate and the limiting baffle help prevent the electroplated sheet substrate from shifting or detaching from the elastic substrate under force.

[0041] Example 3.

[0042] like Figure 6 and Figure 7As shown, based on Embodiment 1, the anti-flying structure includes a plurality of spaced-apart overflow holes 1133, and the other side of the electroplated sheet substrate 12 is bonded and fixed to the side wall of the working section 113. The overflow holes 1133 are through holes provided on the working section 113.

[0043] The advantages of adopting the above-mentioned preferred solution are: the bonding is suitable for diamond grinding wheels that are fine or high-precision, and the overflow hole helps to make the connection between the electroplated sheet substrate and the working section more stable after the glue is fully applied, thereby draining excess glue. In addition, it also helps to accommodate some glue, further enhancing the connection between the electroplated sheet substrate and the working section.

[0044] Example 4.

[0045] Based on Embodiment 1, the anti-flying structure includes a welding layer, which is disposed between the electroplated sheet substrate 12 and the working section 113, for welding and fixing the electroplated sheet substrate 12 to the side wall of the working section 113.

[0046] It should be noted that in this embodiment, the welding layer is pure nickel foil or Cu / Ni composite foil, and resistance welding is performed.

[0047] The advantages of adopting the above preferred solution are: welding is suitable for coarse or fine grinding diamond wheels, and the weld layer helps to improve the stability of the connection between the electroplated substrate and the working section.

[0048] Example 5.

[0049] like Figure 8 As shown, based on Embodiment 1, the anti-flying structure includes a thermoplastic curing block 14 manufactured by an insert molding integrated process, the thermoplastic curing block 14 being circumferentially wrapped around the electroplated sheet substrate 12 and the working section 113.

[0050] The beneficial effect of adopting the above preferred solution is that the thermoplastic curing block is conducive to fixing the electroplated sheet substrate and the elastic substrate in the circumferential direction.

[0051] Preferred, such as Figures 9 to 12 As shown, the working section 113 has a second limiting hole 1134 extending inward from the side wall away from the elastic transition section 112, and a first limiting hole 121 extending inward from the side wall of the electroplated sheet substrate 12. The first limiting hole 121 and the second limiting hole 1134 are overlapped. The thermoplastic curing block 14 has a limiting insert 141 and a mounting groove 142 inside. The electroplated sheet substrate 12 and the working section 113 are adapted to be disposed in the mounting groove 142, and the limiting insert 141 is adapted to be inserted into the first limiting hole 121 and the second limiting hole 1134.

[0052] The advantages of adopting the above preferred solution are: the limiting plug is adapted to be inserted into the first limiting hole and the second limiting hole, which is conducive to fixing the electroplated sheet substrate and the working section in the mounting groove.

[0053] Preferred, such as Figures 9 to 12 As shown, limiting plates 1135 are fixedly provided on both sides of the working section 113, and limiting grooves 143 are provided on both sides inside the thermoplastic curing block 14. The two limiting plates 1135 are respectively adapted to be inserted into the two limiting grooves 143.

[0054] It should be noted that in this embodiment, if multiple elastic grinding parts 1 and multiple support parts 2 alternately abut against each other in the circumferential direction to form a grinding ring, and cooperate with the grinding wheel base 3 to form a cup-shaped grinding wheel, then the limiting insert plate 1135 is fixedly arranged on the radial side walls of the working section 113, and the limiting groove 143 is arranged on the radial sides inside the thermoplastic curing block 14. If multiple elastic grinding parts 1 and multiple support parts 2 alternately abut against each other in the circumferential direction to form a grinding ring, and cooperate with the grinding wheel base 3 to form a peripheral grinding wheel, then the limiting plate 1135 is fixedly installed on the two side walls of the working section 113 in the axial direction, and the limiting groove 143 is installed on both sides of the thermoplastic curing block 14 in the axial direction.

[0055] The advantages of adopting the above preferred solution are: the limiting plate combined with the limiting groove helps to improve the connection stability between the elastic substrate, the electroplated sheet substrate and the electroplated grinding layer.

[0056] Preferred, such as Figures 9 to 12 As shown, the working section 113 is provided with a second limiting tooth 1136 on both sides of the side wall, and the electroplated sheet substrate 12 is provided with a first limiting tooth 122 on both sides of the side wall. The first limiting tooth 122 and the second limiting tooth 1136 are overlapped. The thermoplastic curing block 14 is provided with a third limiting tooth 144 on both sides inside. The first limiting tooth 122 and the second limiting tooth 1136 are connected to the third limiting tooth 144 in a concave-convex fit.

[0057] It should be noted that in this embodiment, if multiple elastic grinding parts 1 and multiple support parts 2 alternately abut against each other in the circumferential direction to form a grinding ring, and cooperate with the grinding wheel base 3 to form a cup-shaped grinding wheel, then the second limiting tooth 1136 is disposed on the two radial side walls of the working section 113, the first limiting tooth 122 is disposed on the two radial side walls of the electroplated sheet base 12, and the third limiting tooth 144 is disposed on the two radial sides inside the thermoplastic curing block 14. If multiple elastic grinding parts 1 and multiple support parts 2 alternately abut against each other in the circumferential direction to form a grinding ring, and cooperate with the grinding wheel base 3 to form a peripheral grinding wheel, then the second limiting tooth 1136 is provided on both sides of the working section 113 in the axial direction, the first limiting tooth 122 is provided on both sides of the electroplated sheet base 12 in the axial direction, and the third limiting tooth 144 is provided on both sides of the thermoplastic curing block 14 in the axial direction.

[0058] The beneficial effects of adopting the above-mentioned preferred solution are: the first and second limiting teeth are connected with the third limiting tooth through a concave-convex fit, which helps to improve the stability of the connection between the elastic matrix, the electroplated sheet matrix and the thermoplastic curing block.

The grinding ring is fixedly installed on the end face of the grinding wheel base 3 to form a cup-shaped grinding wheel, or fixedly installed on the outer circumferential surface of the grinding wheel base 3 to form a peripheral grinding wheel.
