Product DescriptionThree-station fully Automatic Centrifugal Casting Machine for cylinder liners8 station centrifugal casting machine for cylinder liner is composed of the multi-station engines and a auxiliary engine. 8 main engines areevenlydistributedon the rotary roundtable.The main engine is rotated to different positions by the rotary round table.Four sets of auxiliary engines is distributed around the rotary round table fixedly.When main engine is rotated to correspondingposition,each auxiliary engine will completerespectivefunction to main engine with cleaning mold ,spraying coating,pouring and extracting the casting.
The main engine's speed is adjustable and steady in the high speed.The Spraying process is Stone Processing Machinery 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:
1Highly automatic
2 high-speed and stable main engine
3security and stability control system
4less area
5Excellent spraying qualityFeature
main engine
The main engines are obtained high-speed and stable as feature. The key factor of casting's qualityis whethertube molds are smooth running.Therefore, The more smooth running of the main engine is ,the less rMachinery for Food, Beverage & Cereal adial run-out of the tube molds in high speed,the more uniform wall thickness of cylinder liner is and the more stable the structure performance will be.
The main engine adopts cantileverstructure with the bearing base adopting cast iron material, so it has a good shock absorption capacity. The main engine use ac frequency conversion mTransmitter otor and vector control converter. Riding wheelis rotated by V belt.So it ensures that the tube molds can be controlled with precise speed governing.Spindlebraking system ensures the fast stop of the tube molds. So the productivity can be improved.Rotary round table
8 station engines areevenlydistributedon the rotary roundtable.Each main engine is switched to different position by rotary round table.The rotary round table is controlled by AC servo.When rotating it is rapid,smooth and accurate position.Also the speed is adjustable.Cleaning system
Residual coatingsin the inner wall of mold are cleaned rapidly.The cleaning bogie moves axial directionalong the mold. On the cleaning bogie there is a spinning brush which clean the inner wall of mold.The brush can be changed to meet the different inner radius of mold. The cleaning device contains spraying nozzles and corresponding dust collector.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 movement of the spray lance is controlled by servo.So it has the feature of smooth running and position adjustable.It ensures the uniformity of the coatings.The movement of the spray lance can be divided into three section.The speed and distance can be adjust in each section.Coordinate the rotation speed of the tube molds withthe spraying pressure, the requirements of a variety of complex spraying processes can be satisfied.Cooling system
The cooling system is real-time monitoring of the tube mold's temperature and control the spray water cooling.The mold's temperature has a very big influence on the quality of the cylinder liner, Especially in metallographic structure and hardness of the cylinder liner.If the mold's temperature is too high, the wet coating material shall inflames, which can cause uneven coatings.It can't ensure the surface quality of the cylinder liner.In the meanwhile the service life of the molds shall be shortened. If the mold's temperature is too low. When pouring the coating can't dry out completely.The bubbles can't dissolve out completely before pouring. when the molten iron of high temperature meets the wet coating material, the casting defects such as the white casts and air pores are likely to occur to the cylinder liner.
It can be displayed in thTest Instrument e HMI. The cooling nozzles are evenly arranged in the axial direction above the tube molds.According to Cable Tools the cooling parameters,when pouring or solidification process,the cooling system will splash water cooling to the outer of the tube molds,which controls the the tube mold's temperature in the appropriate process range.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. The position and speed of the casting extraction can be set up and adjusted.
Pouring system
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 automaticallyand 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.
