Description

A roller grinding wheel for processing crystal glass beads

technical field

The utility model relates to a grinding wheel.

Background technique

At present, the grinding wheels for processing crystal glass beads on the market are all traditional steel grinding wheels. In order to speed up the grinding speed and precision, corundum will be sprinkled on the grinding wheel when the steel grinding wheel and the crystal glass bead blank are ground together. The defect is that the emery is wasted. More and powdery corundum will pollute the production environment.

Contents of the invention

The purpose of the invention of the utility model is to overcome the shortcomings of existing grinding wheels for processing crystal glass beads, and provide a roller grinding wheel for processing crystal glass beads with novel structure, high grinding speed and high precision.

The technical scheme of the utility model is:

A roller-type grinding wheel for processing crystal glass beads, which is composed of a shaft sleeve, a connecting plate and a drum-type grinding disc, the shaft sleeve is connected to the grinding disc through the connecting plate, and the shaft sleeve and the grinding disc are arranged concentrically; There are multiple grinding grooves arranged parallel to each other regularly, and the drum-type grinding disc is composed of a steel inner layer and an emery outer layer on it.

Preferably, the shape of the grinding groove is one of arc, semicircle or V shape, which is used for processing crystal glass beads of different shapes.

Preferably, the diameter of the grinding wheel is between 157mm-159mm, the thickness of the outer layer of emery is within 0.5mm, the ratio of the thickness of the outer layer of emery to the diameter of the grinding disc is the most coordinated, and the service life is the longest.

Preferably, the connecting plates are two symmetrical pieces, which are respectively arranged at the left and right ends, which not only connect firmly but also save material and light weight compared to solid parts, which reduces production costs.

According to the technical scheme of the utility model, a roller grinding wheel for processing crystal glass beads is composed of a shaft sleeve, a connecting plate and a roller grinding disc. Multiple rows of grinding grooves can process multiple crystal glass beads at the same time, which improves the working efficiency. High efficiency, the outer layer of corundum is set on the inner layer of steel, which greatly improves the grinding speed and precision, and there is no problem of polluting the production environment by throwing corundum. In summary, the roller grinding wheel for processing crystal glass beads has the advantages of novel structure, high processing efficiency, high grinding speed and high precision, and can be widely used in the crystal glass bead processing industry.

Detailed ways

Below in conjunction with Fig. 1 and Fig. 2, the utility model is further described.

A kind of roller grinding wheel for processing crystal glass beads as shown in Fig. 1 and Fig. 2 is made of axle sleeve 5, drum grinding disc 1 and left and right two connecting plates 4. The axle sleeve 5 and the connecting plate 4 are made of steel, and the drum grinding disc 1 is made of a steel inner layer 12 and an emery outer layer 11 thereon.

The shaft sleeve 5 is connected to the grinding disc 1 through the connecting plate 4, and the centers of the shaft sleeve 5 and the grinding disc 1 are at the same position, that is, concentrically arranged. The drum grinding disc 1 is provided with a plurality of grinding grooves 2 arranged in parallel and regularly. The shape of the grinding grooves 2 is any one of arc, semicircle or V shape, and is used for processing crystal glass beads of different shapes. The diameter of the grinding disc 1 is between 157mm-159mm, and the thickness of the corundum outer layer 11 is within 0.5mm. The connecting plates 4 are two left and right symmetrical pieces, which are respectively arranged at the left and right ends of the inner side of the drum type grinding disc 1, which saves material and is light in weight compared with solid parts.

The above-mentioned embodiment is only a better implementation mode of this patent, and all the structures, features, and changes and modifications in the spirit and principle described by this technical solution belong to the protection scope of this patent.
