Abstract
The utility model discloses an automatic control system for the quenching of vacuum gas-quenching furnaces, which is implemented through carrying out real-time adjustment on the quenching speed of a workpiece in a furnace body through a series of steps such as the acquisition of feedback information of a flowmeter, data processing, computer processing, application setting, PLC (programmable logic controller) control and the speed control of an air cooling motor, thereby ensuring the quenching quality of the workpiece. Under equal inflation pressure conditions, the cooling speed of workpiece quenching is determined according to the rotating speed of the air cooling motor. The quicker the air speed and the velocity are, the quicker the cooling speed is, therefore, the cooling speed of a quenched workpiece can be controlled through an air speed. The change of the air speed is detected in rear time by using a flowmeter, a feedback signal is subjected to data processing so as to obtain the quenching process curve at present, and then the quenching process curve at present is compared with a preset process curve, thereby obtaining a corresponding adjustment signal; and at the moment, the adjustment signal is sent to a PLC control module, so that the rotating speed of the air cooling motor is changed to carry out real-time adjustment on the air speed, thereby ensuring the quenching quality of the workpiece.
Description
Technical field
The utility model relates to a kind of vacuum air-quenching furnace quench cooled Controlling System, belongs to the vacuum heat treatment field.
Background technology
Present vacuum air-quenching heat treatment furnace is just controlled the inflation cooling pressure in the stove, when the specific works situation changes in the stove, can't be according to the particular case of the speed of cooling in the stove, come automatically to control in real time speed of cooling, the cooling temperature control of the quenching that makes can't be adjusted speed of cooling according to the processing requirement of cooling, thereby affects the quenching effect of workpiece.
The utility model content
Technical problem to be solved in the utility model provides a kind of vacuum air-quenching furnace cooling automatic control system, can detect in real time the variation of quench cooled wind speed, with reference to default process curve, adjusts in real time.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of vacuum air-quenching furnace quench cooled automatic control system, and its innovative point is to comprise following steps:
A. obtain the under meter feedback information, described under meter is arranged in the vacuum air-quenching furnace cooling draught pipe, detects in real time the wind speed that ventilated machine produces by under meter;
B. data processing is carried out pre-treatment with the analog signals of under meter feedback;
C. Computer Processing is according to wind speed simulation amount signal acquisition workpiece quenching process curve this moment that obtains;
D. programming relatively obtains quenching technology curve and default quenching technology curve this moment by computer, obtains to adjust signal.
E.PLC control is sent the control module with PLC with the adjustment signal that obtains;
F. ventilated machine speed of cooling control obtains to adjust signal feedback to ventilated machine frequency variation signal receiving end with the PLC control module, adjusts in real time the rotating speed of ventilated machine, thus controlled wind speed.
The utility model has the advantage of: under the equal condition of inflation pressure, the speed of cooling of workpiece quenching is determined by the rotating speed that ventilated machine is arranged.The wind speed flow is faster, and speed of cooling is faster, so the speed of cooling of quenching workpiece can be controlled by wind speed.Utilize under meter to detect in real time the variation of wind speed, and with feedback signal after data processing, obtain this moment the quenching technology curve, and with default process curve relatively, thereby obtain the corresponding signal of adjusting, to adjust signal and give the PLC control module this moment, thereby change the rotating speed of ventilated machine, adjust in real time wind speed, guarantee the quenching quality of workpiece.
