Description

Technical Field

[0001] The present invention relates to a fixture installation structure of a cemented carbide tooth product alignment and flipping device, and more particularly to a fixture installation structure of a cemented carbide tooth product alignment and flipping device on a cemented carbide tooth loading and unloading device for CVD coating, which improves the structure of the fixture installed on the cemented carbide tooth product alignment and flipping device specifically used for a process requiring alignment and flipping, thereby facilitating installation and disassembly and improving productivity. Background Art

[0002] Generally speaking, cutting tools are mainly used for cutting ferrous, non-ferrous metals, and non-metallic materials. They are tools that are usually installed on machine tools to cut products into desired shapes.

[0003] Cemented carbide teeth for cutting tools are sintered alloys obtained by mixing diamond powder or cemented carbide powder with metal powders such as iron (Fe), tungsten (W), cobalt (Co), copper (Cu), nickel (Ni), tin (Sn), copper tin (CuSn), zinc (Zn), copper zinc (CuZn), and silver (Ag) as a binder (bond), and then firing.

[0004] In the molding step before sintering, the mixed powder is put into the cavity of the rectangular parallelepiped for primary pressure molding, and the mixture after primary pressure molding is put into the cavity of the carbon mold, and a puncher is used to apply a relatively large pressure to form a cutting head corresponding to the shape of the dental punch. The blade is fired in a sintering furnace to form a blade of a certain shape to complete a diamond blade or blade.

[0005] The fired carbide teeth need to go through the inspection step and PVD (Physical Vapor Deposition) or CVD (Chemical Vapor Deposition) coating step to become finished products. At this time, the various types of carbide teeth products have different shapes and need to be aligned. In the inspection equipment or transfer equipment that needs to be flipped according to different processes, the coating position becomes different depending on the cutting surface and the non-cutting surface, so the alignment and flipping process is required.

[0006] In the prior art, for CVD coating, the fired carbide teeth are manually turned over and inserted according to the cell shape of the tray. In the process of recycling and inspection after coating, they are also turned over for inspection, resulting in problems such as reduced productivity and increased defective rate.
