The processing of cemented Infusion Apparatus Mould Manufacturers materials is still difficult. As shown in the upper and lower of the color TV adjustment block mold The chamfer of the punch makes the end surface that can be formed by simple processing have to be EDM again, and the sharp corner is very easy to damage in use. If the production process of the ferrite is considered, the production of the material belongs to the powder metallurgy production process.
Use an M4 screw; fix the fixed-measuring claw of the internal measuring dry sub-meter on the bracket plate 1, and move the claw end to the bracket plate 2. Furnace temperature is 880/9000, heat preservation 4/6>, and then with the furnace cooling to 730/7500 and then heat preservation 3/5 at a cooling rate lower than 30 0/h to 550/600 0 and then open the furnace cover half, so that When the furnace temperature is reduced to 450/5000,
the annealing cycle is usually 24h and the workpiece can be finished according to the drawings. The hardness of the cemented carbide is easy to be annealed for mechanical processing. Combining the two together by welding can not only ensure the red hardness and wear resistance of the mold, but also maintain the overall plasticity of the mold, which greatly reduces the cost of the mold. It is suitable for occasions with low accuracy requirements.
Other parts (parts not in direct contact with the heated workpiece). GT-35 steel-bonded cemented carbide is made of chromium-molybdenum steel as the binding phase, and tungsten carbide as the hard phase is made of powder metallurgy. GT-35 Steel Bonded Carbide Quenching and Tempering Process Curve One Seeding Table Simple Calibration Table Wei Li, Zhang Xuqiang School of Mechanical and Electrical Engineering and Automation, University of Defense Technology, Changsha 410073, Hunan, China The accuracy of the indication of the table before disassembly is required.
