Medical Treatment Drip Chamber Mould Factory

The temperature of the heat sink was significantly lowered, so the ideal heat sink shape was not obtained. The problem of stuck bolts due to thermal deformation hinders practical use. In addition, the complicated forging shape increases the deformation resistance during forging, which becomes a major difficulty in forming. Research and development of the world's first forged steel brake discs with fins have been used in recent high-speed Shinkansen vehicles.

In manufacturing, there is a reverse included angle between the brake sliding surface and the thermal deformation. Use pre-deformation to reduce thermal deformation. When the wheel is installed, the sliding surface and the corresponding sliding material plane become parallel.The practicality of forged steel brake discs with heat sinks..

Therefore, the process plan for the forged steel brake disc with the heat sink is also determined. In the past, the shape of the heat sink was forged three times, and the deformation resistance of the material was increased. The original shape of forged steel brake discs with heat sinks is a split type that can be replaced by (a) stress expansion coefficient (b) fracture toughness value according to the vehicle marshalling state.

In addition, in order to Medical Treatment Drip Chamber Mould Factory reduce thermal deformation, a certain amount of pre-deformation is given in the opposite direction from thermal deformation during manufacturing. Therefore, in order to improve the processability of heat sink forming, research has been conducted on the adjustment of die cooling time, the increase of die temperature, the development of high-temperature adhesion lubricants, and the development of molds to prevent defects in heat sinks.

Due to the excellent heat-resistant crack resistance of forged steel, it is not necessary to replace the disk, so the original split type is improved to the integral type, and the deviation of the installation bolt hole distance is also prevented.
