Description

Technical Field

[0001] This utility model relates to the field of abrasive technology, and more specifically to an abrasive block. Background Technology

[0002] With technological innovations in the production processes of microcrystalline glass ceramic slabs, stone, and artificial quartz stone slabs, the polishing of large-format slabs is becoming increasingly common. Polishing ordinary small-format slabs presents challenges. Due to their small size and numerous seams between slabs, conventional abrasive tools are typically integral flat modules. During flat polishing, the small angle of entry between the abrasive block and the slab makes it difficult to wear down the abrasive matrix. Generally, the matrix is ​​worn down at the seams, exposing new diamonds for continuous polishing and improved efficiency and effect. Large-format slabs, with their large length and width spans and fewer seams, suffer from insufficient continuous wear of the abrasive matrix, preventing timely exposure of new diamonds and resulting in lower continuous polishing efficiency. Therefore, further improvements to existing technologies are necessary. Summary of the Invention

[0003] The purpose of this invention is to provide a stable and reliable arc-shaped grinding block with a resin-inlaid metal and diamond spiral cutting tooth structure, which allows for a large cutting angle of the cutting teeth, rapid wear of the matrix, more new diamond cutting edges, and improved polishing efficiency, in order to overcome the shortcomings of the existing technology.

[0004] The present invention achieves the above-mentioned objective by adopting the following technical solution: an arc-shaped grinding block with a resin-inlaid metal combined with diamond spiral cutting teeth structure, characterized in that it includes a metal substrate, two or more spiral cutting teeth, and a resin inlay layer, wherein the spiral cutting teeth are welded to the metal substrate and the resin inlay layer fills the empty parts of the cutting teeth.

[0005] As a further explanation of the above scheme, the axis of the spiral cutter teeth is arranged at a certain angle to the center line of the grinding block, and the angle is 0°≤R≤90°.

[0006] Furthermore, the spiral cutter teeth can be either left-handed or right-handed, depending on the direction of the grinding disc's rotation (for example, right-handed spiral is used when rotating counterclockwise, and vice versa), in order to optimize the cutting path.

[0007] Furthermore, the spiral cutter teeth can be continuous or intermittent. Intermittent cutter teeth can achieve stepped wear through segmented welding, which further promotes the consumption of the grinding block body.

[0008] Furthermore, the resin inlay layer can be either a thermosetting resin layer or a thermoplastic resin layer, such as a thermosetting resin (e.g., phenolic resin) or a thermoplastic resin (e.g., polyamide resin). The former has high wear resistance, while the latter is easy to repair. It fills the gaps between the cutting teeth, fixes the diamond particles, and is consumed preferentially over the metal matrix during the wear process, thereby gradually exposing new diamond cutting edges.

[0009] Furthermore, two or more helical cutter teeth are arranged parallel to each other.

[0010] Furthermore, the metal substrate is set on the card holder substrate, which facilitates quick installation onto the grinding disc and improves replacement efficiency.

[0011] The beneficial effects that this utility model can achieve by adopting the above-mentioned technical solution are:

[0012] This utility model adopts an arc-shaped module structure mainly composed of a metal substrate, two or more spiral cutting teeth, and a resin inlay layer. The metal substrate is set on the card base substrate, the spiral cutting teeth are welded to the metal substrate, and then the empty parts of the cutting teeth are inlaid with resin. Because the cutting teeth are installed in a spiral manner, the cutting angle of the cutting teeth is large, which can make the matrix wear faster, more new diamonds emerge, and improve polishing efficiency. At the same time, when the grinding disc drives the grinding block to rotate and cut, the grinding block swings, and each spiral cutting head contacts the surface of the workpiece. The cutting surface formed by its motion trajectory is a plane, which reduces residual ripples on the surface of the plate and improves the polishing quality. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.

[0017] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature, and in this description of the utility model, "at least" means one or more, unless otherwise explicitly specified.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components.

Furthermore, "above," "below," and "over" the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Above," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings, making the technical solution and beneficial effects of this utility model clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] like Figure 1 and Figure 2 As shown, this utility model is an arc-shaped grinding block with a resin-inlaid metal combined with diamond spiral cutting teeth structure. It includes a metal substrate 1, two or more spiral cutting teeth 2, and a resin inlay layer 3. The metal substrate is disposed on a mounting base 4 for easy and quick installation onto the grinding disc, improving replacement efficiency. In this embodiment, there are five spiral cutting teeth 2, which are arranged parallel to each other and spaced apart. The cutting teeth can be continuous or discontinuous. The angle R between the axis of the spiral cutting teeth and the center line of the grinding block is within the range of 0°≤R≤90°, preferably 30°≤R≤60°, to balance the depth of cut and cutting resistance. In this embodiment, this angle is 30 degrees.

[0022] The spiral cutting teeth 2 are welded to a metal substrate 1, which is an iron substrate. A resin inlay layer fills the empty spaces between the cutting teeth. The resin inlay can be any type of thermosetting resin or thermoplastic resin. In this embodiment, thermosetting resin (such as phenolic resin) or thermoplastic resin (such as polyamide resin) is used. The former has high wear resistance, while the latter is easy to repair. The resin layer wears down preferentially, ensuring that the diamond particles are continuously exposed, thus avoiding the decrease in polishing efficiency caused by uneven wear of the matrix, as is the case with traditional abrasive blocks. Function: To fill the gaps between the cutting teeth, fix the diamond particles, and be worn down preferentially before the metal substrate during the wear process, thereby gradually exposing new diamond cutting edges.

[0023] The manufacturing process includes the following steps:

[0024] a. Metal substrate processing: An arc-shaped substrate is formed by precision casting or machining, with pre-reserved grooves for welding blades on the surface.

[0025] b. Welding of diamond cutting teeth: The diamond cutting teeth (containing a metal binder layer with diamond particles) are fixed in the groove of the substrate by high-temperature brazing or laser welding to ensure the precision of the cutting tooth angle and spacing.

[0026] c. Resin filling: Resin material is injected into the gaps between the blades, and an inlay layer is formed by hot pressing or injection molding to ensure that the resin layer is firmly bonded to the blades and the substrate.

[0027] Compared with the prior art, this utility model adopts a method of setting a metal substrate on a card base, welding spiral blades to the metal substrate, and then inlaying resin into the empty parts of the blades. Because the blades are installed in a spiral arc shape, the cutting angle of the blades is large, which can make the matrix wear faster and more new diamonds emerge. When the polishing machine swings laterally, in order to polish the edge of the plate better, the grinding block is usually swung more than halfway out of the edge of the plate. The resin-inlaid blades can protect the blades from colliding with the plate when the polishing machine swings laterally out of the edge, allowing the grinding block to smoothly transition to the plate surface.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
