Spring Centrifugal Casting Machine

Two-station fully Automatic Centrifugal Casting Machinefor cylinder linersTwo-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 andconsistency. 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 less area 2 more production efficiency 3high level of automation--all operations are performed by one person 4 suit for cylinder liner's continuous production with large quantities and single item.
Features
main engine
The main engines are obtained high-speed and stable as feature.The key factor affecting the product quality is whether the tube mold runs smooth and rotatory. Therefore, the smooth of the main engine is required to be very high. In the high-speed operation, the radial run-out of the tube mold is smaller, the wall thickness of the cylinder liner is more even, and the structure performance is more stable.
The main engine adopts four supporting wheel structure with the bearing base adopting cast iron material, so it has a good shock absorption capacity. The surfaces of the supporting wheels are processed with hardening and fine grinding processes. The main engine use ac frequency conversion motor and vector control converter. Riding wheelis rotated by V belt.So it ensures that the tube molds can be controlled with precise speed governing. Regenerative braking system ensures the fast stop of the tube molds. So the productivity can be improved.
Auxiliary engine
Auxiliary engine has accurate locating control .Cleaning, spraying and tool for casting extraction mechanisms are compactly arranged on the mobile platforms. Through the position shift of the mobile platforms,the cleaning system,spraying system and extracting system will be in working positions of themselves.Servo positioning control is used in spraying system,extracting system and mobile platform.So they have accuracy control in the position and speed.It demands the strict requirements of processes and shorten the operating time,thus improving work efficiency.
Spray coating
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 spray lance moves with servo control.So the spray lance has a smooth movement and an adjustable position, which ensures the uniformity of the spray coating. The speed of the spray lance can be divided into three sections. The movement distance and speed of each section can be adjusted.With the rotating speed and spraying pressure of the tube mold, it can meet the requirements of a variety of complex spraying processes.
