Description

TECHNICAL FIELD

[0001] The present application relates to the field of grinding wheel manufacturing, in particular to a diamond grinding wheel and a process method. BACKGROUND

[0002] In the prior art, a diamond grinding wheel is formed by fixing a diamond working ring (referred to as a working ring hereinafter) and a base. One of the processes of the technical progress is: from a continuous working ring without a water groove (referred to as a common grinding wheel hereinafter) to a working ring with a water groove (including a through tooth, an inner tooth, an outer tooth, or a combination thereof), and then to a thin slice tooth spliced water groove type working ring (referred to as a spliced grinding wheel hereinafter). The significant feature of the development process is: under the same conditions of the same diameter of the grinding wheel, the same total content of diamond, and the like, the more the water grooves, that is, the thinner and the more the working teeth (referred to as thin slice teeth hereinafter) are divided in the circumferential direction of the working ring. The grinding wheel is formed by splicing multiple independent thin slice teeth and fixing them with the base, or by connecting multiple thin slice teeth in a ring with a non-working ring and fixing them with the base, or by connecting multiple thin slice teeth in segments with a non-working layer and fixing them with the base. As the circumferential direction of the thin slice teeth becomes thinner and thinner, the strength and rigidity of the thin slice teeth become difficult to guarantee the normal operation of the grinding wheel. Moreover, as the number of thin slice teeth increases, the difficulty of fixing the thin slice teeth with the base also increases, resulting in a decrease in manufacturing efficiency and an increase in manufacturing cost. SUMMARY

[0003] The technical problem to be solved by the present application is to provide a diamond grinding wheel and a process method to solve the above problems.

[0005] The beneficial effects of this invention are as follows: By wrapping the thin-toothed material with a thermoplastic curing block to form an insert molding, it is beneficial to make the thin-toothed material thinner, that is, to develop the circumferential thickness of the thin-toothed material in a direction of becoming thinner and thinner, which makes the application of micro-nano diamond grinding wheels promising to be realized or expanded; by arranging and splicing multiple insert moldings around the grinding wheel matrix, it is beneficial to solve the problem of difficult bonding of thin-toothed material, reduce manufacturing difficulty, and improve production efficiency; for the spliced ​​grinding wheel after the thin-toothed material is thinned, the strength and rigidity issues are reinforced by bonding with a suitable thermoplastic material, thereby meeting the requirements. The various grinding conditions facilitate the expansion of applications for composite grinding wheels with thin-tooth profiles.

Simultaneously, under the same price conditions, higher-priced but higher-performance bonding agents can be selected, improving the grinding capability of the thin-tooth profiles. The reduced spacing between diamond particles in the thin-tooth profiles also improves diamond utilization and extends the wheel's lifespan. This results in a substantial reduction in manufacturing costs and further improvement in performance for composite grinding wheels with thin-tooth profiles, significantly increasing their cost-effectiveness.

[0017] Furthermore, a plurality of the insert moldings are wound around the end face or circumferential face of the grinding wheel base.

[0018] The beneficial effects of adopting the above-mentioned further solutions are: it facilitates the formation of end-face grinding wheels or peripheral grinding wheels, thereby increasing the applicability.

[0019] Furthermore, the tip of the thin-film tooth protrudes from the thermoplastic curing block and is flush with the tip of the thermoplastic curing block.

[0021] Furthermore, the angle between the inner wall of the annular structure formed by the multiple insert moldings and the horizontal plane is between 95 degrees and 110 degrees.

[0022] The beneficial effect of adopting the above-mentioned further solution is that it helps the cooling water in the manifold to eliminate the negative impact of centrifugal force and flow quickly to the grinding surface of the grinding wheel.

[0049] 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. The present invention is suitable for two types of grinding wheels: end face grinding wheels and peripheral grinding wheels. This description only provides examples for end face grinding wheels. For peripheral grinding wheels, adaptive adjustments can be made based on the mechanism of the present invention, and known technologies can be used to achieve this.

[0050] like Figures 1 to 13As shown, a diamond grinding wheel includes: multiple insert forming parts 1, a grinding wheel base 2, a manifold 3, a pressure plate 4, multiple auxiliary parts 5, and multiple water-passing and chip-removing grooves 6; the multiple insert forming parts 1 are wound around the grinding wheel base 2, the pressure plate 4 abuts against the insert forming parts 1 and is mounted on the grinding wheel base 2 through the auxiliary parts 5, the manifold 3 is disposed in the middle of the grinding wheel base 2 and is mounted on the grinding wheel base 2 through the auxiliary parts 5, and the water-passing and chip-removing grooves 6 are disposed on the side of the insert forming parts 1. On the wall; the insert molding component 1 includes: a thermoplastic curing block 11, a thin tooth 12 and a solidifying block 13, the thin tooth 12 is disposed on the solidifying block 13, the thermoplastic curing block 11 wraps around the thin tooth 12 and is connected to the solidifying block 13, the solidifying blocks 13 in the plurality of insert molding components 1 are wound around the grinding wheel base 2, the thermoplastic curing blocks 11 in the plurality of insert molding components 1 abut against each other to form a ring structure, and the water-passing chip removal groove 6 is disposed on the side wall of the thermoplastic curing block 11.

[0051] It should be noted that, in a preferred embodiment of the present invention, the consolidation block 13 and the thermoplastic curing block 11 can exist as a whole, and the thermoplastic curing block 11 wraps around the periphery of the thin-plate tooth 12, and the thermoplastic curing block 11 is wound around the grinding wheel base 2.

[0052] In the technical solution of the present invention, the auxiliary component 5 is a bolt or screw.

[0053] The beneficial effects of this invention are as follows: By wrapping the thin-toothed material with a thermoplastic curing block to form an insert molding, it is beneficial to make the thin-toothed material thinner, that is, to develop the circumferential thickness of the thin-toothed material into a thinner direction, which makes the application of micro-nano diamond grinding wheels promising to be realized or expanded; by wrapping and splicing multiple insert moldings around the grinding wheel matrix, it is beneficial to solve the problem of difficult bonding of thin-toothed material, reduce manufacturing difficulty, and improve production efficiency; for the spliced ​​grinding wheel after thinning of thin-toothed material, the strength and rigidity issues are reinforced by bonding with a suitable thermoplastic material, thereby meeting the usage conditions of various grinding conditions, which is beneficial to the application expansion of spliced ​​grinding wheels after thinning of thin-toothed material; when using the same amount of diamond, thinning of thin-toothed material can significantly reduce the amount of binder used, reduce manufacturing costs, and at the same price, higher-priced but higher-performance binder materials can be selected to improve the grinding ability of thin-toothed material. The reduced spacing between diamond particles in thin-toothed material can also improve diamond utilization and increase lifespan.

[0054] It should be noted that, in the technical solution of the present invention, during the process of the thin-plate tooth 12 developing towards thinner plates, ideally, only one diamond can exist in the circumferential thickness direction of the thin-plate tooth 12, that is, a single layer of diamond is set in the circumferential thickness direction of the thin-plate tooth 12.

[0055] Preferred, such as Figures 6 to 11 As shown, the water-cooled chip removal groove 6 is provided on one side wall or both side walls of the thermoplastic curing block 11.

[0056] The beneficial effect of adopting the above-mentioned preferred scheme is that it facilitates the simultaneous grinding, cooling, and chip removal of the composite grinding wheel formed after the thin-plate teeth are thinned during grinding.

[0057] Preferred, such as Figure 10 As shown, when the water-cooled chip removal groove 6 is provided on one side wall of the thermoplastic curing block 11, in any two adjacent insert molding parts 1, the side of one thermoplastic curing block 11 with the water-cooled chip removal groove 6 abuts against the side of the other thermoplastic curing block 11 away from the water-cooled chip removal groove 6.

[0058] The advantages of adopting the above preferred solution are: it facilitates the thermoplastic curing blocks in multiple insert molding parts to abut against each other in the circumferential direction and to form a ring-shaped grinding wheel around them.

[0059] Preferred, such as Figure 10 As shown, in any two adjacent insert molding parts 1, the water-cooled chip removal grooves 6 on one side wall of the two thermoplastic curing blocks 11 are misaligned in the wear direction.

[0060] It should be noted that, in the technical solution of the present invention, "misaligned setting" means that as the thermoplastic curing block 11 is gradually consumed by grinding, the water-passing and chip-removing groove 6 on one thermoplastic curing block 11 and the water-passing and chip-removing groove 6 on the other thermoplastic curing block 11 alternate in the axial direction.

[0061] The beneficial effect of adopting the above-mentioned preferred scheme is that it facilitates the alternating appearance of water-cooled chip removal grooves in the grinding wear direction of the grinding wheel, thereby optimizing the cooling and chip removal effect.

[0062] Preferred, such as Figures 4 to 8 As shown, when the water-cooled chip removal groove 6 is provided on both side walls of the thermoplastic curing block 11, in any two adjacent insert molding parts 1, the water-cooled chip removal groove 6 on one thermoplastic curing block 11 abuts against the water-cooled chip removal groove 6 on the other thermoplastic curing block 11.

[0063] The advantages of adopting the above preferred solution are: it facilitates the thermoplastic curing blocks in multiple insert molding parts to abut against each other in the circumferential direction and to form a ring-shaped grinding wheel around them.

[0064] Preferred, such as Figures 4 to 8 As shown, the water-cooling and chip-removing grooves 6 on both sides of the thermoplastic curing block 11 are staggered in the wear direction, and in any two adjacent insert molding parts 1, the water-cooling and chip-removing grooves 6 on the side where the two thermoplastic curing blocks 11 abut against each other are staggered in the wear direction.

[0065] The beneficial effect of adopting the above-mentioned preferred scheme is that it facilitates the alternating appearance of water-cooled chip removal grooves in the grinding wear direction of the grinding wheel, thereby optimizing the cooling and chip removal effect.

[0066] Preferably, a plurality of the insert molding parts 1 are wound around the end face or circumferential face of the grinding wheel base 2.

[0067] The advantages of adopting the above preferred scheme are: it facilitates the formation of end face grinding wheels or peripheral surface grinding wheels, thereby expanding the applicability.

[0068] Preferred, such as Figures 9 to 11 As shown, the top of the thin-plate tooth 12 protrudes from the thermoplastic curing block 11 and is flush with the top of the thermoplastic curing block 11.

[0069] It should be noted that when the tip of the thin-plate tooth 12 protrudes from the thermoplastic curing block 11 and is flush with the tip of the thermoplastic curing block 11, the wear rate of the thermoplastic curing block 11 should be greater than or equal to the wear rate of the thin-plate tooth 12.

[0070] The advantages of adopting the above preferred solution are: it helps to form a semi-enclosed effect where the tip of the thin sheet tooth is flush with the tip of the thermoplastic curing block, so as to ensure that the thin sheet tooth can work normally.

[0071] Preferred, such as Figure 12 and Figure 13 As shown, the angle between the inner wall of the annular structure formed by the plurality of insert moldings 1 and the horizontal plane is between 95 degrees and 110 degrees.

[0072] It should be noted that the outer diameter portion of the water-cooled chip removal groove 6 is sealed by the thermoplastic curing block 11 to prevent unnecessary leakage of cooling water.

[0073] The advantages of adopting the above preferred solution are: it helps the cooling water in the manifold to eliminate the negative impact of centrifugal force and quickly flow to the grinding surface of the grinding wheel.

[0074] like Figure 14 As shown, a method for manufacturing diamond grinding wheels includes the following steps:

[0075] S1: Thin-plate teeth 12 are made using diamond and a bonding agent;

[0076] S2: Make a mold according to the setting position of the water-cooled chip removal groove 6 and the thin-plate teeth 12 in step S1;

[0077] S3: Place the thin-plate tooth 12 from step S1 into the mold of step S2;

[0078] S4: Inject thermoplastic curing material into the mold in step S2, and after cooling, open the mold to obtain insert molding part 1;

[0079] S5: Repeat step S4 above multiple times to obtain multiple insert molding parts 1;

[0080] S6: Multiple insert molding parts 1 are wound around the grinding wheel base 2, and the insert molding parts 1 are fixed on the grinding wheel base 2 using the pressure plate 4 and auxiliary parts 5;

[0081] S7: Use auxiliary component 5 to fix the manifold 3 onto the grinding wheel base 2.

[0082] It should be noted that in the technical solution of this invention, the molding process of inserting a pre-prepared insert of a different material into the mold, injecting resin, and then bonding and solidifying the molten material with the insert to form an integrated product is called the insert molding process. The thin-plate teeth in this invention are inserts.

[0083] In step S1, the binder can be metal, resin, ceramic, electroplating / chemical plating, brazing, organic (such as polyurethane, rubber) materials, etc., and various thin-plate teeth 12 can be made with diamond using known corresponding processes. For example, when the binder is metal powder, it can be mixed and sintered with diamond using powder metallurgy technology to form a thin-plate tooth 12 with metal binder. The thin-plate tooth 12 can have a solid block 13 to facilitate solidification and connection, or it can have a substrate that is easy to manufacture (such as thin-plate teeth manufactured by electroplating / chemical plating binder process). Electroplating / chemical plating thin-plate teeth 12 can also contain only diamond and binder (i.e., electroplating / chemical plating metal layer, the same below), becoming a substrate-free electroplating / chemical plating thin-plate tooth, so as to reduce the circumferential thickness or the wear resistance caused by the substrate, thereby adapting to the application of micro and nano-sized diamond abrasive grains.

[0084] In step S3, when multiple types of thin-plate teeth 12 are formed by multiple binders, two or more types of thin-plate teeth 12 can be placed in the mold of step S2 and the multiple types of thin-plate teeth 12 are made to abut against each other in sequence. Then, the composite insert molded part 1 with multiple types of thin-plate teeth 12 is obtained by insert molding process in step S4. By utilizing the characteristics of different binders, optimization or compensation is achieved, and the result of adapting to working conditions or improving the performance of the grinding wheel is finally achieved.

[0085] In step S4, the thermoplastic curing material includes, but is not limited to, plastic, rubber, and other materials.

[0086] By controlling the degree of bonding agent inclusion on the electroplated / chemically plated single-layer diamond sheet tooth 12, a certain amount of diamond is exposed. Then, by using a suitable thermoplastic material in the insert molding process, part of the thermoplastic material is filled into the diamond exposed area, which, together with the bonding agent, achieves the holding of the diamond and acts as a bonding agent. This helps to adjust the holding force on the diamond, improve the self-sharpening performance of the spliced ​​grinding wheel, and shorten the manufacturing cycle of electroplating / chemical plating, thereby reducing manufacturing costs.

[0087] For example, a nickel layer with a diamond particle size of 20% can be inlaid on the circumferential surface of the electroplated / chemically plated thin sheet tooth 12, that is, 80% of the diamond is exposed. Using thermoplastic materials (such as nylon), through the insert molding process, part of the nylon is filled into the exposed area of ​​the diamond, and together with the 20% nickel layer, it is inlaid to hold the diamond, thereby shortening the electroplating / chemical plating time, adjusting the holding ability of the diamond, and achieving the appropriate self-sharpening performance.

[0088] In step S6, when multiple types of thin-plate teeth 12 are formed by multiple binders, and then multiple types of insert molding parts 1 are formed, two or more types of insert molding parts 1 can be alternately wound around the grinding wheel base 2 to realize a composite grinding wheel with composite properties, thereby adjusting the performance of the composite grinding wheel, making up for the shortcomings of the performance of a single binder, and expanding the application range of grinding.

[0089] Specifically, for dry grinding metal / electroplated bonded grinding wheels, the concept of insert molding can be adopted to integrate the metal / electroplated thin-plate teeth with a metal material with high thermal conductivity (such as copper or aluminum) into a single component. Furthermore, by adopting the water-cooled chip removal groove method mentioned above, a fan can be added to create a strong airflow chip removal groove. This achieves efficient cooling and rapid chip removal for the thin-plate tooth composite grinding wheel, improving the performance of the dry grinding composite grinding wheel and thus facilitating the expansion of dry grinding tool applications.

[0090] The beneficial effects of this invention are as follows: Through the insert molding process, this invention facilitates the further development of thin-plate tooth technology, continuously improving the performance of the composite grinding wheel; it helps solve the bonding problem of thin-plate tooth composite grinding wheels, enabling them to adapt to high-speed machining; it enhances the strength and rigidity of thin-plate tooth composite grinding wheels, expanding the application prospects of micro / nano diamonds in composite grinding wheels; it allows for the use of a single-layer diamond method in thin-plate tooth composite grinding wheels, achieving micro-grinding water-cooling and chip removal channels on the grinding surface at the unit of abrasive grain, enabling simultaneous grinding, cooling, and chip removal, thus achieving high-quality, high-speed, and high-precision grinding; it facilitates the efficient and low-cost production of thin-plate tooth composite grinding wheels; it is suitable for dry grinding composite grinding wheels with thin plates, achieving efficient cooling, rapid chip removal, significantly reducing the amount of bonding agent raw materials, and greatly lowering manufacturing costs.
