China Casting Machine for Auto Cylinder Centrifugal Casting Machine for Piston Ring Centrifugal Cast

What is Centrifugal Casting?
Centrifugal casting is a process that delivers castings of very high material soundness, and thus is the technology of choice for applications likejet engine compressor cases,petrochemical furnace tubes, manymilitary products, and otMould her high-reliability applications.
In the centrifugal casting process, molten metal is poured into a spinning die. The die can be spinning either on a vertical or horiCustomized Service for Electronics zontal axis depending on the configuration of the desired part. Ring and cylinder type shapes are cast vertically; tubular shapes are made with the horizontal centrifugal process. Either process may be used to produce multiple parts from a singlecasting.External structures and shaping can be cast in place to significantly reduce post-processing including machining orfabrication.
Because of the high g-forces applied to the molten metal in the spinning die, less dense material, including impurities, "floats" to the I.D. where it is subsequently removed by machining. Solidification is managed directionaOther Safety Products lly under pressure, from the O.D. to the I.D., avoiding any mid-wall shrinkage, leaving a defect-free structure without cavities or gas pockets.Eight-stationcentrifugal casting machinefor cylinder sleeve8 station centrifugal casting machine for cylinder liner is composed of the multi-station engines and a auxiliary engine. 8 main engines areevenlydistributed on 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 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.
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 radial 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 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.Spindlebraking system ensures the fast stop of the tube molds. So the productivity can be improved.
The composition and features of the machineThe 8-station rotating-plate-typeCutting & Fold-bend Machine centrifugal casting machine is composed of rotating platform, cantilever-type centrifugal casting main engine, automaticcleaning device, automatic painting device, automatic pouring device, cast tube crosswise device and mould cooling system.Cantilever-type centrifugal casting machineThe cantilever-type centrifugal casting machine is the core of the complete machine. 8 cantilever-type centrifugal casting machines are distributed uniformly in the rotating working platforms. The variable frequency motor drives the main shaft through belt transmission structure to realize the rotation of the mould and the centrifugal pouring of the casting. The mould is installed in the subpanel and the main shaft rotating speed could realize stepless speed regulating, which would meet the process requirements of casting of different diameters.
In order to make the mould stop quickly, the cantilever-type centrifugal casting machine is equipped with a brakingdevice, which would reduce the working pace of the machine andimprove working efficiency.
Each centrifugal casting machine is equipped with safety protection cover to realize the safetyproduction of the casting.
2.Rotary Table
Rotary table is the keypart of the eight-station rotary table type centrifugal casting machine which can achieve the multiple-station working requirements of centrifugal casting machine. The rotation of the table is achieved throughthe gear driving mechanism to drive the rotary support relying on the servo motor, and the entire rotary motion is precisely positioned by the servo control. The rotary table rotates intermittently and pauses at every rotation of 45 degrees, and each station completes its corresponding motion, and it will re-rotate to the next station after all stations complete the work. The rotary table rotates in a circle in which it completesthe centrifugal casting process of one cast. The rotaryspeed can be set according to the process requirement of each station, and be precisely controlled.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.
Electric control system
Control system use PLC as the control core and use the man-machine interface as the monitoring system.It controls the Horticulture & Gardening Products 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.The casting of our machine produce
