Product DescriptionTwo-station fully Automatic Centrifugal Casting Machine for cylinder liners
Two-station fully automatic centrifugal casting machine is composed of the two engines and a auxiliary engine. The two engines which are controlled by VFD are parallel layout. The two engines share auxiliary engine and pouring equipment. Auxiliary engine is controlled by servo and it includes cleaning, spraying, pouring, cooling, casting extraction devices .The whole process are controlled automatically.
The main engine's speed is adjustable and steady in the high speed.The Spraying process is very advanced of multistage velocity control. The key process parameters are real-time monitor and adjusted by automatic control system. So it can ensure the casting process parameters repetition and consistency. It eliminates the influence of artificial factors to the casting process parameters. So it ensures stable quality of the casings.
The feature of machine:
1 Highly automatic
2 high-speed and stable main engine
3 security and stability control system
4 less area
5 Excellent spraying quality
The main engines are obtained high-speed and stable as feature.
Auxiliary engine has accurate locating control .Cleaning, spraying and tool for casting extraction mechanisms are compactly arranged on the mobile platforms.
It has excellent spray coating quality.The function of tube mold's inner coating:
1 reduce the impact of metal liquid on the tube molds
2 reduce the peak temperature of the tube molds
3 effectively prolong the service life of the tube molds
4 increase the friction force between the tube molds and liquid metal
5 shorten the time of the pour-in metal liquid to achieve the tube rotation speed and also facilitate the casting pieces to release from the molds in tube drawing process.
The cooling system is real-time monitoring of the tube mold's temperature and control the spray water cooling.
Tool for casting extraction
Casting extraction mechanism is controlled by servo and Pneumatic control system. So it is very accurate and reliable.It can extract the casting smoothly from the tube molds.
Automatic pouring device is composed of pouring vehicle, pouring ladle, etc.
Pouring vehicle can serve two engines for pouring respectively.
The ladle's pouring speed can be adjusted.The automatic weighing device is used in pouring vehicle,which can ensure the consistency of the weight for each batch of cylinders. The weight of the molten iron in the ladle can be displayed on the big screen and the records can be printed.
Electric control system
Control system use PLC as the control core and use the man-machine interface as the monitoring system.It controls the whole process automatically and monitors the whole production process.Control system has the perfect protective measures, such as over-current protection, over-load protection, etc. The process parameters of the main engine and the auxiliary engine all can be adjusted and stored in the man-machine interface such as work positions and velocity. It meets the production process requirement of a variety of cylinder liner castings in a certain range.
