Multi-Station Centrifugal Casting Machine for Cylinder Head Gasket

Eight-station cylinder liner centrifugal casting machine
TechnicalScheme8-station rotating-disc-type centrifugal casting machine is composed of an annular rotary table, 8 cantilever-type centrifugal casting main engines (including mould cooling equipment), a set of mould automatic painting equipment, a set of automatic pouring device, a set of mould cleaning device, a set of casting crosswise device and electrical control system. The stable motion, compact structure and high automation degree are the best feature of whole machine.
The control system adopts PLC control. The main engine combines the AC variable frequency motor with the AC VVVF (variable voltage and variable frequency) to compose the stepless speed control system, with the speed regulating being stable and the regulating scope being wide. It adopts the touch screen to monitor the working status of the centrifugal casting machine, show the parameters of pouringprocess and machine failure warning information. The control system can be operatedeither manually or automatically.
The 8-station rotating-plate-type centrifugal casting machine is designed for 8 stations, with each station being responsible forone or several process motions. 8 working stations are distributed asfollows: one cleaning and end cap mounting station, one painting station, one paint drying station, one pouring station, three casting cooling stations and one end cover dismounting and part picking-up station. In the running process, specific process procedures are as follows: working station 1: mould cleaning-mounting the front end cap; station 2: painting; station 3: paint drying; station 4: pouring; station 5-7: casting cooling; station 8:end cap dismounting and casting take off.
It calls for two operators, with one taking charge of the end cap mounting and dismounting and the other being responsible forthe operation of the pouring device.
The 8-station rotating-plate-type 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.
