Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic blades, and particularly relates to a novel welded ceramic blade. Background Art

[0002] Ceramic turning tools are advanced cutting tools, which have the advantages of high hardness, good wear resistance, and high-temperature stability.

[0003] At present, the integral ceramic blade is relatively brittle and is prone to integral fracture when subjected to impact or excessive cutting force. Content of the Utility Model

[0004] The purpose of the utility model is to provide a novel welded ceramic blade to solve the above-mentioned problems.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a novel welded ceramic blade, which includes:

[0006] A blade base body, which is in the shape of a polygonal thin sheet. A sinking groove is formed on the corner end face of the blade base body, and a weld groove is formed on the edge of the sinking groove.

[0007] Multiple ceramic piece bodies are clamped into the sinking groove and attached to the step surface of the sinking groove. The multiple ceramic piece bodies are connected to the blade base body by brazing, and the weld is filled in the weld groove.

[0008] As a further description of the above technical scheme:

[0009] An installation hole is formed in the middle of the blade base body.

[0010] As a further description of the above technical scheme:

[0011] A positioning hole is formed in the middle of the ceramic piece body. A positioning bolt passes through the positioning hole and is screwed on the blade base body.

[0012] As a further description of the above technical scheme:

[0013] The cross-section of the blade base body is triangular, and the cross-section of the ceramic piece body is rhombic.

[0014] In summary, due to the adoption of the above technical scheme, the beneficial effects of the utility model are:

[0015] In the present utility model, sufficient strength support is provided by the blade substrate. Multiple ceramic blade bodies are brazed onto the blade substrate. Even if the ceramic blade bodies are impacted, only the corresponding ceramic blade bodies are damaged, and the blade substrate will not be damaged. Different ceramic blade bodies on the blade substrate can be replaced for use, extending the service life of the ceramic blade. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-3 , the present utility model provides a technical solution: a new type of welded ceramic blade, including:

[0023] A blade substrate 1, which is in the shape of a polygonal thin sheet. A sinking groove 2 is provided on the corner end face of the blade substrate 1, and a weld groove 3 is provided on the edge of the sinking groove 2;

[0024] Multiple ceramic blade bodies 4 are snapped into the sinking groove 2 and are attached to the stepped surface of the sinking groove 2. Multiple ceramic blade bodies 4 are connected to the blade substrate 1 by brazing, and the weld is filled in the weld groove 3;

[0025] A mounting hole 5 is provided in the middle of the blade substrate 1 to facilitate the installation of the blade substrate 1 on the tool bit;

[0026] A positioning hole 6 is provided in the middle of the ceramic blade body 4. A positioning bolt 7 passes through the positioning hole 6 and is screwed onto the blade substrate 1, which has an auxiliary positioning effect on the installation of the ceramic blade body 4;

[0027] The cross-section of the blade substrate 1 is triangular, and the cross-section of the ceramic chip body 4 is rhombic.

[0028] Working principle: First, install the blade substrate 1 on the tool head of the lathe. Second, the ceramic chip body 4 performs turning on the workpiece rotating at high speed. Then, even if the ceramic chip body 4 is impacted, the blade substrate 1 will not be damaged. Finally, turn the blade substrate 1 and align another ceramic chip body 4 with the workpiece.

[0029] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
