SUMMERY OF THE UTILITY MODEL

To the not enough that exists among the prior art, the utility model provides a wear-resisting mill structure, it has solved the mill among the prior art and has easily been worn and torn to lead to grinding the problem of inefficacy.

According to the embodiment of the utility model, a wear-resisting mill structure, it includes the annular disk body that is pieced together the piece amalgamation by four first pieces of block and a second and forms, first piece of block with the piece is pieced together to the second all is provided with the arc mill face, and the arc mill face is gone up the sunken gomphosis groove that is provided with, and all that is provided with the wearing layer is inlayed to the gomphosis inslot first piece of block with all wearing layers meet and form annular wear-resisting structure after the piece amalgamation is pieced together to the second.

Among the above-mentioned technical scheme, realize inlaying the wearing layer at the arc mill face through the gomphosis groove, the wearing layer has higher hardness, can improve the wear resistance of mill for it is more difficult by wearing and tearing.

Further, the wear-resistant layer comprises a fitting part positioned in the fitting groove and a wear-resistant part covering the upper surface of the arc-shaped grinding surface.

Furthermore, a plurality of strip-shaped grooves are formed in the embedding grooves in a sunken mode, reinforcing ribs are embedded in each strip-shaped groove, and a plurality of annular reinforcing ribs are formed on the annular disc body after the first splicing blocks and the second splicing blocks are spliced.

Further, the wear-resistant layer is connected with the arc-shaped grinding surface through surfacing.

Compared with the prior art, the utility model discloses following beneficial effect has:

the wear-resistant layer is connected to the arc-shaped grinding surface in a build-up welding mode, so that the wear-resistant capability of the grinding disc is improved, the service life of the grinding disc is prolonged, and the normal grinding is ensured.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like, indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

As shown in fig. 1 and 2, the present embodiment provides a wear-resistant grinding disc structure, which includes an annular disc body 3 formed by splicing four first splicing pieces 1 and one second splicing piece 2, wherein the first splicing piece 1 has a large size, and the second splicing piece 2 has a small size, so that the efficiency and quality of mechanical processing (such as turning, milling, etc.) can be improved by processing the annular disc body 3 in blocks;

the first splicing block 1 and the second splicing block 2 are both provided with arc-shaped grinding surfaces, the arc-shaped grinding surfaces are concavely provided with embedded grooves, and the embedded grooves are embedded with wear-resistant layers 4, and all the wear-resistant layers 4 are connected to form an annular wear-resistant structure after the first splicing block 1 and the second splicing block 2 are spliced.

In the above embodiment, the wear-resistant layer 4 is embedded in the arc-shaped grinding surface through the embedding groove, and the wear-resistant layer 4 has higher hardness, so that the wear resistance of the grinding disc can be improved, and the grinding disc is less prone to being worn.

As shown in fig. 3, the wear-resistant layer 4 preferably includes a fitting portion 5 located in the fitting groove and a wear-resistant portion 6 covering the upper surface of the arc-shaped wear surface, so that the wear-resistant layer 4 completely covers the arc-shaped wear surface.

As shown in fig. 1, 2 and 3, preferably, the embedding grooves are provided with a plurality of strip-shaped grooves, each strip-shaped groove is embedded with a reinforcing rib 7, and all of the reinforcing ribs are formed on the annular disc body 3 after the first block 1 and the second block 2 are spliced, and the arrangement of the reinforcing ribs can improve the mechanical stability of the wear-resistant layer 4 on the disc body.

Particularly, in the abrasive disc provided by this embodiment, when the disc body is processed, the first segment 1 and the second segment 2 are first spliced together, and then the reinforcing rib and the wear-resistant layer 4 are welded by overlay welding, wherein the reinforcing rib and the wear-resistant layer 4 are both made of wear-resistant materials (such as Cu — Ni alloy) for overlay welding.

Compare in prior art, the wear-resisting mill structure that this embodiment provided has following beneficial effect:

the wear-resistant layer 4 is connected to the arc-shaped grinding surface in a build-up welding mode, so that the wear-resistant capacity of the grinding disc is improved, the service life of the grinding disc is prolonged, and the normal grinding is ensured.
