Diamond grinding wheels have become the main component of polishing machinery.

However, there are many problems with diamond grinding wheels during use. For example, if not handled properly, they can easily break, causing damage to the grinding wheel and even injuries to people. Some operators use the side of the grinding wheel for grinding at will, regardless of the type of grinder or the type of grinding wheel, and cannot control the final polishing effect; the manufacturing cost of the grinding wheel is high and it is difficult to replace; the grinding wheel must be polished continuously during the polishing process. Spraying the grinding fluid, the utilization efficiency of the grinding fluid is low and the grinding cost is increased.

Utility model content

In order to improve the problems of high diamond grinding wheel polishing costs and high operating risks, the utility model proposes a diamond polishing wheel sleeve.

The diamond polishing wheel sleeve of this application adopts the following technical solution:

An annular sleeve belt for a diamond polishing wheel, including an abrasive belt layer, a flexible buffer base pad and a base layer. The flexible buffer base pad and the base layer are bonded through a first adhesive layer. The abrasive belt layer and the flexible buffer base pad are bonded together. through the second adhesive layer. The flexible buffer base pad is made of polymer foam material, and the abrasive belt layer includes diamond sand grains and a cloth base.

Further, the diamond sand particles are planted on the cloth base using electrostatic sand planting method.

Further, the flexible cushioning base pad is made of EVA blended high water-absorbent fiber foam.

Further, the first adhesive layer is a fireproof glue, specifically a polyurethane glue or an inorganic fireproof glue containing a vinyl retardant.

Further, the second adhesive layer is double-sided tape or adhesive.

Further, the base layer is made of flannel material.

Furthermore, the flannel annular body formed in one piece has no interface, the flexible cushioning base pad is also an annular structure, and the flexible cushioning base pad and the base layer are bonded by a first adhesive layer. , the cloth base of the abrasive belt layer and the flexible cushioning base pad are bonded through a second adhesive layer, and the cloth base layer is also integrally woven and formed on the outside of the flexible cushioning base pad.

The utility model has the following beneficial effects:

In the processing of certain products, such as 3C products and hardware products, you can not use a diamond grinding wheel, but directly sleeve the diamond polishing wheel annular sleeve outside the metal polishing wheel to form a kind of diamond polishing surface. The diamond grinding wheel structure means that even if the operation is improper, the abrasive belt will only be damaged, and the operator only needs to replace it with a new belt to continue working, which reduces the cost and loss caused by the diamond grinding wheel breaking during the polishing process. At the same time, this process There will be no production safety issues caused by grinding wheel fragments popping out; secondly, it has a better polishing effect. Compared with ordinary diamond grinding wheels, the setting of a flexible buffer base pad facilitates grinding of uneven positions and improves polishing efficiency. Efficiency and effect; Thirdly, because the flexible cushioning base pad and the base layer have a certain liquid absorption capacity, the retention of the polishing fluid is improved, thereby improving the polishing effect of the polished parts.

Detailed ways

Referring to Figure 1, a diamond polishing wheel annular sleeve includes an abrasive belt layer 1, a flexible buffer base pad 21 and a base layer 22. The flexible buffer base pad 21 is an ethylene-vinyl acetate copolymer (EVA) foam material. The base pad 21 and the base layer 22 are bonded through a first adhesive layer 4. The first adhesive layer 4 may be a fireproof adhesive, especially a foamed fireproof adhesive, specifically a polyurethane hairspray containing a vinyl retardant. The abrasive belt layer 1 and the flexible buffer base pad 21 are bonded together through a second adhesive layer 3. The second adhesive layer 3 may be 3M double-sided tape or other adhesives. The base layer 22 is made of fleece material. Since the sanding process will generate heat due to friction, the abrasive belt layer, the flexible cushioning base layer and the base layer will easily detach. Therefore, foamed fireproof glue is used, which has a certain heat insulation effect, making the base layer and the flexible cushioning base layer separate. The connection between them is more stable.

The sand belt layer 1 includes diamond sand grains 11 and a cloth base 12. The diamond sand grains are planted on the cloth base using an electrostatic sand planting method.

The flexible buffer base pad 21 is made of EVA blended high water-absorbent fiber, which has good polishing fluid retention ability, improves the polishing effect of the workpiece during processing, and greatly reduces the polishing fluid loss compared with diamond grinding wheels. Used, the overall cost of polishing is reduced.

This product is processed using the following methods:

Method 1: First, form a flannel base layer through an integrated weaving process, then apply glue on the base layer, and then add an EVA cushion layer to its outer layer through 3D printing and other processes; apply glue again on the outside of the EVA cushion layer and adhere the ring shape The cloth base layer is implanted with diamond sand grains on the cloth base through the method of electrostatic sand planting.

The annular sleeve of the diamond polishing wheel made by the above method prevents the existence of interfaces in the annular sleeve, reduces the possibility of tearing of the interface due to stress during the polishing process, and increases the service life of the abrasive belt.

Method 2: The abrasive belt layer 1, the flexible buffer base pad 21 and the base layer 22 are all sheet materials. After the three are adhered together, the polishing wheel annular sleeve punches the sheet material into a rectangular shape according to the size of the polishing wheel. , and then sew and paste the short side to form a ring-shaped polishing wheel abrasive belt.

The annular sleeve of the diamond polishing wheel made by method two has low processing cost, high flexibility, and can quickly adapt to polishing wheels of various sizes, but its service life is not as good as that of the finished product made by method one.

How to use: According to the size of the polishing wheel, select the diamond polishing wheel annular sleeve of the corresponding size and adhere it to the outside of the polishing wheel. After use, cut the annular sleeve of the diamond polishing wheel and remove or replace it.

The above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make the foregoing descriptions. The technical solutions described in each embodiment may be modified, or some of the technical features may be equivalently substituted. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the present utility model. Within the scope of new protection.
