Description

Technical Field

[0001] This utility model relates to the field of diamond manufacturing, specifically to a diamond grinding wheel manufacturing device made of composite materials. Background Technology

[0002] The abrasive components of grinding wheels come in a wide variety of formulations, each with its own advantages. However, the wheel body is generally made of either steel or aluminum, and the bonding strength between the abrasive formulation and the wheel body varies. Steel-based grinding wheels are widely used in heavy industry due to their high strength and good heat resistance, especially in applications requiring high mechanical stress and high-temperature environments. Aluminum-based grinding wheels are known for their lighter weight and good thermal conductivity, making them suitable for precision machining and high-speed applications. Nevertheless, regardless of the matrix material used, the performance and lifespan of a grinding wheel largely depend on the abrasive formulation and bonding strength.

[0003] Among the many abrasive formulations, commonly used ones include corundum, silicon carbide, and diamond, each with its specific application scenarios and performance characteristics. For example, corundum is widely used for grinding common metals due to its high hardness and good wear resistance; silicon carbide is suitable for grinding cemented carbide and ceramic materials due to its high heat resistance and good self-sharpening properties; and diamond, with its ultra-high hardness and excellent grinding performance, performs exceptionally well in grinding non-metallic and difficult-to-machine materials.

[0004] Not all abrasive formulations achieve good bond strength on the grinding wheel body. Some abrasives exhibit significant weaknesses in adhesion; for example, certain abrasives with numerous pores are prone to cracking during the firing process, leading to decreased adhesion. Furthermore, some highly brittle abrasives are prone to breakage and detachment under impact and thermal stress, thus affecting the grinding wheel's lifespan and machining accuracy. These problems are particularly prominent in the actual use of grinding wheels, potentially leading to frequent quality issues such as abrasive cracking and ring detachment. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide a diamond grinding wheel manufacturing device made of composite materials.

[0006] To achieve the objective of this utility model, the technical solution adopted is as follows:

[0007] An apparatus for manufacturing diamond grinding wheels from composite materials, comprising:

[0008] The first pressing structure includes an inner mold ring and an outer mold ring that are symmetrically arranged, and a diamond powder pressing cavity is provided between the inner mold ring and the outer mold ring.

[0009] An upper clamping clamp is provided at the upper end of the diamond powder pressing cavity, and a lower clamping clamp is provided at the lower end of the diamond powder pressing cavity.

[0010] The diamond powder in the diamond powder pressing cavity is pressed and formed into a diamond abrasive block by the axial cooperation of the inner mold ring and the outer mold ring, the upper circumferential surface of the upper clamping fixture and the lower circumferential surface of the lower clamping fixture.

[0011] The second clamping structure includes a toner filling cavity that contacts the diamond abrasive block, and an inner mold ring is provided at the other end of the diamond abrasive block.

[0012] An upper hot-pressing forming outer clamp is provided on the upper end face of the diamond abrasive block, and a lower hot-pressing forming clamp is provided on the lower end face of the diamond abrasive block.

[0013] The toner filling cavity is filled with toner.

[0014] An inner core is provided at the other end of the toner filling cavity;

[0015] An upper hot-pressing inner clamp is provided at the upper end of the toner filling cavity;

[0016] The diamond abrasive block and toner are pressed and solidified by the cooperation of the inner mold ring, the upper hot-pressing outer clamp, the upper hot-pressing inner clamp, the inner core, and the lower hot-pressing clamp.

[0017] In a preferred embodiment of the present invention, the upper clamping clamp is an upper clamping clamp with a first stepped clamping surface.

[0018] In a preferred embodiment of this utility model, the lower clamping clamp is a lower clamping clamp with a second stepped clamping surface.

[0019] In a preferred embodiment of this utility model, the upper hot-pressing outer clamp is an upper hot-pressing outer clamp with a third-step pressing surface.

[0020] In a preferred embodiment of this utility model, the lower hot pressing forming fixture is a lower hot pressing forming fixture with a fourth step pressing surface.

[0021] The beneficial effects of this utility model are as follows:

[0022] This invention allows the diamond abrasive material to be manufactured as a single unit with the base material, maintaining the consistency of the two materials and eliminating the need for additional adhesives to fix the diamond abrasive. Attached Figure Description

[0024] Figure 2 This is a schematic diagram of the structure of the present invention. Figure 2 . Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, in the following descriptions, well-known structures and technologies have been omitted to avoid unnecessary confusion regarding the concept of this utility model.

[0026] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] like Figure 1 Or, as shown in Figure 2, a composite material diamond grinding wheel manufacturing apparatus is designed to achieve a seamless bond between the diamond abrasive and the matrix material without the use of additional glue.

[0028] The first clamping structure 100 includes a symmetrically designed inner mold ring 110 and an outer mold ring 120, forming a diamond powder pressing cavity 130 between them. An upper clamping clamp 140 and a lower clamping clamp 150 are respectively disposed at the upper and lower ends of the pressing cavity. The upper clamping clamp 140 has a first stepped clamping surface 141, while the lower clamping clamp 150 is equipped with a second stepped clamping surface 151. Through the precise axial fit of the inner mold ring 110 and the outer mold ring 120, and the clamping action of the upper and lower clamping clamps, the diamond powder can be effectively compacted and shaped within the pressing cavity 130, ultimately forming a high-density diamond abrasive block 1.

[0029] Next, we proceed to the manufacturing stage of the second clamping structure 200. In this design, one end of the diamond abrasive block 1 contacts the toner filling cavity 210, while the other end is provided with an inner mold ring 260. An upper hot-pressing outer clamp 220 and a lower hot-pressing clamp 230 are respectively installed on the upper and lower end faces of the abrasive block 1. The upper hot-pressing outer clamp 220 has a third-step clamping surface 221, while the lower hot-pressing clamp 230 is equipped with a fourth-step clamping surface 231.

[0030] Furthermore, an inner core 240 is provided at the other end of the toner filling cavity 210, and an upper thermoforming inner clamp 250 is configured at its upper end. Through the coordinated clamping of the inner mold ring 260, the upper thermoforming outer clamp 220, the upper thermoforming inner clamp 250, the inner core 240, and the lower thermoforming clamp 230, the diamond abrasive block 1 and the toner 2 can be tightly bonded and solidified. The upper thermoforming inner clamp 250 mainly plays a secondary fastening role in this process, ensuring the stability and strength of the overall structure.

[0031] First, the diamond powder in the diamond powder pressing cavity 130 is pressed and formed into diamond abrasive block 1 by the axial cooperation of the inner mold ring 110 and the outer mold ring 120, the upper clamping clamp 140 and the lower clamping clamp 150. Then, the diamond abrasive block 1 and the toner 2 are pressed and solidified by the cooperation of the inner mold ring 260, the upper hot pressing outer clamp 220, the upper hot pressing inner clamp 250, the inner core 240 and the lower hot pressing clamp 230. The upper hot pressing inner clamp 250 mainly plays a secondary fastening role.

[0032] This invention achieves seamless bonding between the diamond abrasive and the substrate material through an integrated production process, ensuring material consistency between the two and completely eliminating the glue fixing step required in traditional processes.

[0033] The above shows and describes the basic principles, main features, and advantages of this utility model.

[0034] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of this utility model as defined by the appended claims and their equivalents.
