Description

Technical Field

[0001] The utility model belongs to the technical field of tool coating preparation, in particular to a preparation device for nano-composite titanium silicon nitride tool coating. Background Art

[0002] The physical or chemical vapor deposition method is used to coat one or more layers of several microns of high hardness, high wear resistance, and high temperature resistance metal or non-metal compound coating on the surface of the carbide, high-speed steel or ceramic blade substrate with good strength and toughness, so as to reduce the abrasive and chemical wear between the tool and the workpiece, protect the tool substrate material, and improve the cutting efficiency of the tool.

[0003] In the early days, hard coating materials prepared by physical vapor deposition technology were usually simple TiN and TiC coatings, which had high resistance to mechanical wear, abrasive wear and low friction coefficient. However, the high-temperature oxidation resistance of the coating was low and it could not be applied to high-speed machining or dry cutting conditions. Currently, elements such as Cr and Al are added to TiN coatings to form multi-component multi-element coatings, such as TiCrN and TiAlN coatings. The microhardness reaches HV3000, which has higher resistance to mechanical wear and abrasive wear than TiN and TiCN coatings, and the application temperature of the coating is also increased to above 800°C.

[0004] Before the tool is coated, it needs to be installed on the bracket and then the bracket is sent to the coating machine for coating. However, traditional tools are fixed to the bracket by screws or bolts. Therefore, professional tools are required during the tool disassembly and assembly process, so the operation is cumbersome and time-consuming.

[0005] Therefore, it is necessary to provide a new preparation equipment for nano-composite titanium silicon nitride tool coating to solve the above technical problems. Utility Model Content

[0033] The second step: synchronously start the two dual-axis motors 5 to reverse, which can make the four internal threaded sleeves 6 rotate, so that the four L-shaped rods 1 7 drive the four L-shaped rods 2 8 to move away from each other, and then the four L-shaped rods 2 8 drive the two clamping blocks 3 to move away from each other, so that the tool 2 can be easily taken out, making the structure simple, and easy to disassemble, assemble and fix the tool 2, which can provide convenience for the coating of the tool 2 in the later stage.
