In the current casting process, the tilting process control requirements of aluminum alloy cylinder head casting are high. The traditional hydraulic tilting cylinder head gravity casting machine has seriously affected the yield of casting products due to the instability of tilting control. At present, the tilting gravity casting machine is mainly based on the tilting mode of oil cylinder. This type of machine has some defects, such as heavy model, difficult tilting speed driven by hydraulic pressure, poor positioning accuracy, poor consistency of casting process, difficult process quality control of customers, unreasonable ergonomic design, high labor intensity of workers and inability to collect smoke generated in the casting process.
The servo tilting gravity casting machine newly developed by Wanfeng adopts servo control technology to realize accurate control of tilting speed, displacement and positioning compared with the past hydraulic drive. Accurate servo tilting control technology can not only realize the smooth transition of tilting, but also provide a good guarantee for the strict casting tilting process control. 180 ° precise tilting control can be realized, providing more accurate process control technology and scheme for domestic cylinder head gravity casting process control.
It is worth mentioning that the new generation of servo tilting gravity casting machine adopts excellent ergonomic design and scientific operation station, which is more in line with the ergonomic workbench height. There is no need to build a platform and dig a pit. Mold cleaning and mold spraying are more "easy", providing simple and comfortable operation space for workers. The appropriate fore-and-aft tilt angle facilitates the automatic dumping of residual sand in the mold block, manual mold inspection and spraying operation, provides technical feasibility for unmanned automatic casting of cylinder head, and brings great convenience to operators.
