Description
Technical field:
The utility model relates to a kind of liquid aliquot pouring device, particularly the liquid aliquot automatic casting control device of vacuum-casting stove and vacuum rapid hardening furnace interior liquid metal equivalent casting.
Background technology:
At present, in the vacuum drying oven of use, metal is fused into liquid metal in crucible, when casting, extensively adopt the operative employee by peep hole eye-observation casting gate liquid metal head piece size, artificially regulate the crucible reversal rate, thereby realize the approximate equivalent casting of liquid metal.This method of operating, artificial operation factors is very big, the liquid metal casting rate that can not accomplish every stove is the same, promptly in each second of casting cycle, it is unequal that crucible is toppled over the weight of liquid metal that, so just cause the next procedure liquid metal inconsistent cool time, thereby directly influence the uniformity and the uniformity of product.On the other hand, if make automatic casting into, because the crucible reversal rate can not change, rollover characteristics according to crucible, the liquid metal casting rate that crucible is poured out is inevitable fast more first quick and back slow, causes the liquid metal cooling extremely inhomogeneous, has a strong impact on the casting product quality.
The utility model content:
Problem to be solved in the utility model is exactly the drawback at prior art, adopt angular transducer and PID cyclelog to form closed-loop device, automatically control the crucible reversal rate, make each second in casting cycle, crucible is toppled over the weight of liquid metal that and is equated, has promptly realized the equivalent automatic casting of liquid metals; The technical scheme of the utility model technical solution problem is: described liquid aliquot automatic casting control device comprises: angular transducer 1, crucible switching mechanism 2, hydraulic cylinder 3, Hydraulic Station 4, hydraulic control valve 5, PID cyclelog 6; Concrete connection features is: be provided with crucible in the crucible switching mechanism 2, hydraulic cylinder 3 support bars are arranged on the support switching mechanism 2 of crucible switching mechanism 2 both sides, the oil line pipe of hydraulic cylinder 3 is connected a side of hydraulic control valve 5, the opposite side of hydraulic control valve 5 connects Hydraulic Station 4 by pipeline, and the output of PID cyclelog 6 is arranged on the lower end of hydraulic control valve 5.Angular transducer 1 is connected turning cylinder one end of crucible switching mechanism 2, the output of angular transducer 1, the input of connection PID cyclelog 6.The workflow of liquid aliquot automatic casting control device described in the utility model is: liquid aliquot automatic casting control device described in the utility model is when carrying out casting, Hydraulic Station 4 provides pressure oil-source to hydraulic cylinder, PID cyclelog 6 is set the output of predetermined amount according to internal processes, make hydraulic control valve 5 open certain valve, the oil sources of Hydraulic Station 4 outputs drives hydraulic cylinder 3 elongations, hydraulic cylinder promotes 2 upsets of crucible switching mechanism with certain speed and rises, and crucible begins with certain speed pouring liquid metal.In the time of upset, angular transducer 1 is sensed angle and is changed, angular transducer sends the angle delta data to PID cyclelog 6, PID cyclelog 6 calculates the current output valve of change according to angle delta data that returns and inner casting program, change the valve size of hydraulic control valve 5, change the elongation speed of hydraulic cylinder 3, thereby change crucible switching mechanism 2 reversal rates, through close-loop automatic adjustment crucible reversal rate process, the liquid metals equivalent that crucible is watered cast out is watered out, promptly in casting cycle each second, the weight that crucible is poured out liquid metals equates, has realized the equivalent automatic casting of liquid metal.
The beneficial effects of the utility model are: the utility model uses device few, simple to operate, adopt the upset of hydraulic drive crucible, design ingenious, realized the equivalent automatic casting of the liquid metal under the unmanned guard, and casting rate can be set in the PID cyclelog, and can be according to the shape need of crucible, the artificial crucible reversal rate of revising each unit interval in the PID programme-control, thereby make crucible each second pour out weight of liquid metal and can both be subjected to better controlled, finally realize the equivalent automatic casting of liquid metal.The utility model is compared with conventional method, greatly reduces operator's operation easier, has alleviated operator's labour intensity, improves the quality of casting product simultaneously, has improved the yield rate of product.The utility model has been realized: 1, the automatic casting of the liquid metal under the unmanned guard, and prior art to be the operative employee cast; 2, adopt angular transducer and PID cyclelog to form closed-loop device, control the crucible reversal rate automatically; 3, casting rate can be set in the PID cyclelog, and can artificially revise the crucible reversal rate of each unit interval in the PID programme-control according to the shape need of crucible.
