Description

Technical Field

[0001] This utility model relates to the technical field of irregularly shaped steel wire bonded abrasives, specifically an irregularly shaped steel wire bonded abrasive. Background Technology

[0002] Shaped steel wire bonded abrasives are a special grinding tool that combines a shaped steel wire reinforcement structure with bonded abrasive technology. They are mainly used for grinding, polishing, and finishing of hard, brittle, or difficult-to-machine materials such as metals, stone, and composite materials. Their design features use shaped steel wire as a reinforcing skeleton, combined with a binder to fix the abrasive particles, forming a grinding tool that has both high strength and complex grinding trajectories.

[0003] Currently, existing grinding wheels suffer from uneven wear and localized failures that lead to complete replacement. Due to irregular workpiece surfaces or uneven grinding pressure distribution, the abrasive on irregularly shaped steel wire may experience localized excessive wear (such as at the edges and corners), while the steel wire skeleton remains intact. However, the localized failure of the bonding layer and the abrasive affects the overall grinding accuracy, necessitating the replacement of the entire grinding wheel and resulting in material waste. To address this, we propose a cemented grinding wheel with irregularly shaped steel wire. Utility Model Content

[0004] The purpose of this invention is to provide an irregularly shaped steel wire bonded abrasive, which has the advantages of easy replacement and avoidance of waste. It solves the problem that local failure of the bonding layer and abrasive can affect the overall grinding accuracy, requiring the entire abrasive to be replaced, resulting in material waste.

[0007] The grinding blocks are multiple, and multiple identical grinding blocks are combined to form an irregular steel wire bonded abrasive body. A connecting through hole is opened on the inner surface of one end of each grinding block.

[0008] A positioning plate is located on the right side of the connecting shaft, and a connecting bolt is provided on the inner surface of the outer edge of the positioning plate.

[0009] Preferably, the number of threaded holes is multiple, and the included angle between two adjacent threaded holes is equal.

[0010] Preferably, the shaped steel wire bonded abrasive body is disposed at the right end of the outer surface of the connecting shaft, and the shaped steel wire bonded abrasive body is tightly attached to the right side of the limiting spacer ring.

[0011] Preferably, the connecting bolt is adapted to the connecting through hole, and one end of the connecting bolt is threadedly connected to the threaded hole.

[0022] Example 1

[0023] Please see Figures 1-4 As shown, this utility model provides a technical solution: an irregularly shaped steel wire bonded abrasive, comprising:

[0024] A connecting shaft 1 is provided with a limiting spacer 101 at the right end of the outer surface of the connecting shaft 1, and a threaded hole 103 is provided on the inner surface of the limiting spacer 101.

[0025] A plurality of grinding blocks 202 are used, and multiple identical grinding blocks 202 are combined to form an irregular steel wire bonded abrasive body 2. A connecting through hole 201 is provided on the inner surface of one end of the grinding block 202.

[0026] Positioning plate 4 is located on the right side of connecting shaft 1, and connecting bolts 401 are provided on the inner surface of the outer edge of positioning plate 4.

[0027] There are multiple threaded holes 103, and the included angle between two adjacent threaded holes 103 is equal. The shaped steel wire bonded abrasive body 2 is set at the right end of the outer surface of the connecting shaft 1, and the shaped steel wire bonded abrasive body 2 is tightly attached to the right side of the limiting spacer ring 101. The connecting bolt 401 is adapted to the connecting through hole 201, and one end of the connecting bolt 401 is threadedly connected to the threaded hole 103.

[0028] This technical solution involves passing the connecting bolt 401 through the positioning plate 4 and then through the connecting through hole 201 at one end of the grinding block 202, so that the connecting bolt 401 is threadedly connected to the threaded hole 103 on the limiting spacer ring 101. After all the grinding blocks 202 are installed sequentially around the outer surface of the right end of the connecting shaft 1, multiple grinding blocks 202 can be combined to form the irregular steel wire bonded abrasive body 2. At the same time, with the assistance of the limiting spacer ring 101 and the positioning plate 4, the irregular steel wire bonded abrasive body 2 can be clamped and positioned. After clamping the left end of the connecting shaft 1, the connecting shaft 1 is driven to rotate, and the irregular steel wire bonded abrasive body 2 can grind the surface of the workpiece. If the abrasive on the irregular steel wire may experience localized excessive wear, the corresponding worn grinding block 202 can be replaced by loosening and removing the connecting bolt 401, thus avoiding the need to replace the entire abrasive and avoid material waste.

[0029] Example 2

A bearing 302 is provided on the inner side of the annular groove 102. An annular liquid-passing plate 3 is provided on the outer side of the bearing 302. An annular liquid-passing groove 304 is provided on the inner surface of the annular liquid-passing plate 3. A spray nozzle 303 communicating with the annular liquid-passing groove 304 is provided on the inclined surface at the upper end of the annular liquid-passing plate 3. A liquid-passing pipe connector 301 communicating with the annular liquid-passing groove 304 is provided at the upper end of the left side of the annular liquid-passing plate 3.

[0031] This technical solution: After connecting to an external water supply pipe through the liquid pipe connector 301, the annular liquid plate 3 can be kept stable during the rotation and grinding of this grinding wheel, with the assistance of the bearing 302. After the external water enters the annular liquid groove 304 through the liquid pipe connector 301, it can be sprayed outward by the spray nozzle 303. Since the spray nozzle 303 is set on the inclined surface at the upper end of the annular liquid plate 3, the sprayed water can impact the edge of the irregular steel wire bonded grinding wheel body 2, thereby achieving water cooling and dust reduction during grinding, extending the service life of the grinding wheel, and reducing the dust in the working environment.
