Multinomial die forging is consecutive production, rhythm be 15 minutes four.For the unit quenching tank of configuration three pilot trench, can carry out primary quenching at interval of 15 minutes, the cool time that technique is arranged is 45 minutes.Namely after the first pilot trench enters water quenching 15 minutes, second pilot trench starts into water quenching, when the second pilot trench entered water quenching after 15 minutes, 3rd pilot trench starts into water quenching, when 3rd pilot trench enters water quenching 15 minutes, first pilot trench has completed the quenching of 45 minutes, discharging must meet the quenching of next round.The unit quenching tank be made up of three pilot trench is exactly the cyclical operation gone round and begun again like this, realizes the function of consecutive production.
After first group of workpiece is come out of the stove, infrared sensor sends signal, and cooling tower working shaft 11 starts.System default first pilot trench enters the starting stage of operation, first pilot trench endoporus cooling valve 6 and the first pilot trench exterior cooling valve 9 open 80%, and the second pilot trench and the 3rd pilot trench enter the preparatory stage, 3rd pilot trench endoporus cooling valve 4, second pilot trench endoporus cooling valve 5, first pilot trench endoporus cooling valve 6 and the 3rd pilot trench exterior cooling valve 7 all open 10%, unit quenching tank carries out the preparatory stage, and now the first pilot trench has entered the circular flow state of large discharge.
First group of 4 workpiece enters the first pilot trench quenching simultaneously, and cooling medium consumption reaches 80% of total flux.After 2 minutes, workpiece peak heat release mistake, the open degree of system call interception first pilot trench endoporus cooling valve 6 and the first pilot trench exterior cooling valve 9 is 60%.
When first group of workpiece enters the first pilot trench the 13rd minute, namely first 2 minutes of second group of workpiece quenching, first pilot trench endoporus cooling valve 6 and the first pilot trench exterior cooling valve 9 open degree are adjusted to 30% by system, keep the flooding quantity of 30%, simultaneously, the inlet valve 5 and 8 of the second pilot trench is opened to 60% by system, and the second pilot trench enters treats running status.3rd pilot trench endoporus cooling valve 4 and the 3rd pilot trench exterior cooling valve 7 maintain the open degree of 10%.
First group of workpiece enter the first pilot trench quench the 15th minute time, the second pilot trench endoporus cooling valve 5 and the second pilot trench exterior cooling valve 8 are opened large to 80% further, and the first pilot trench endoporus cooling valve 6 and the first pilot trench exterior cooling valve 9 are adjusted to 10%.Second group of workpiece enters the second pilot trench quenching, after 2 minutes, the quenching of the second pilot trench have passed through peak heat release, second pilot trench endoporus cooling valve 5 and the second pilot trench exterior cooling valve 8 are adjusted to 60% by system automatically, open large to 30% by the first pilot trench endoporus cooling valve 6 and the first pilot trench exterior cooling valve 9, the 3rd pilot trench endoporus cooling valve 4 and the 3rd pilot trench exterior cooling valve 7 maintain the open degree of 10% simultaneously.
First group of workpiece enter the first pilot trench quench the 28th minute time, first 2 minutes of namely the 3rd group of workpiece quenching, first pilot trench endoporus cooling valve 6 and the first pilot trench exterior cooling valve 9 open degree are adjusted to 10% by system automatically, second pilot trench endoporus cooling valve 5 and the second pilot trench exterior cooling valve 8 are opened to 30%, 3rd pilot trench endoporus cooling valve 4 and the 3rd pilot trench exterior cooling valve 7 are opened to 60%, and the 3rd pilot trench enters treats running status.
First group of workpiece enter the first pilot trench quench the 30th minute time, 3rd pilot trench endoporus cooling valve 4 and the 3rd pilot trench exterior cooling valve 7 are opened large to 80% further, second pilot trench endoporus cooling valve 5 and the second pilot trench exterior cooling valve 8 are adjusted to the open degree of 10%, and the 3rd group of workpiece enters the 3rd pilot trench quenching.3rd group of workpiece enter the 3rd pilot trench quench 2 minutes time, 3rd pilot trench endoporus cooling valve 4 and the 3rd pilot trench exterior cooling valve 7 are adjusted to 60% again automatically, second pilot trench endoporus cooling valve 5 and the second pilot trench exterior cooling valve 8 are that the 30%, first pilot trench endoporus cooling valve 6 and the first pilot trench exterior cooling valve 9 keep 10%.
First group of workpiece enter the first pilot trench quench the 43rd minute time, the first pilot trench quenching terminates water outlet, and operating machine completed the outward transport of quenching part in 1 minute, then got back to original position, in 1 minute, the 4th batch of workpiece was sent into the first pilot trench, starts again new one and takes turns circulation;
Traffic conditions when three pilot trench continuous quenchings run is shown in Fig. 3.
