Abstract
The invention relates to a device for monitoring the temperature of a main shaft bushing of a press machine. Not less than two holes used for installing temperature sensors are uniformly formed on the periphery of the main shaft bushing; the temperature sensors with same parameters are arranged in each hole for installing the temperature sensors; each temperature sensor is connected with a corresponding interface of a PLC programmable controller through respective signal wires; and an output end of the PLC programmable controller is connected with a main control circuit relay of a main control circuit. Thus, the operation of a main shaft and a connecting rod and the operation of the output end and the main control circuit can be realized.
Description
Technical field
The present invention relates to a kind of pressing machine supervising device, particularly a kind of device for monitoring temperature of main shaft bushing of press machine.Belong to the press technologies field.
Background technology
Main bearing shell is the strength member of pressing machine; he does the relative motion that does not stop at work and bent axle; simultaneously; the motion that power system is transmitted is applied in the connecting rod slider working mechanism; its working environment is comparatively abominable; so; owing to a series of reasons such as insufficient lubrication, lubricated untimely and assembly precision are relatively poor; the phenomenon that main bearing shell usually can occur burning to death takes place; in case the generation of this kind situation; not only can cause the equipment can't operate as normal, in addition can cause equipment badly damaged, until the serious consequence of scrapping.
At present, for the unusual too high phenomenon of temperature of main shaft bushing of press machine, the main preventive measure of being taked are exactly the way of regularly and irregularly carrying out hand inspection, because human negligence inevitably exists, the influence of other outside cause in addition, so, bearing shell also can usually take place sometimes because temperature anomaly, cause the equipment can't operate as normal, in addition can cause equipment badly damaged, until the serious consequence of scrapping.
Summary of the invention
The objective of the invention is to: a kind of device for monitoring temperature of main shaft bushing of press machine is provided, overcome existing pressing machine and adopt the way of regularly and irregularly carrying out hand inspection, because human negligence inevitably exists, the influence of other outside cause in addition, bearing shell also can usually take place sometimes because temperature anomaly, cause the equipment can't operate as normal, in addition can cause equipment badly damaged, until the serious consequence of scrapping.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of device for monitoring temperature of main shaft bushing of press machine, it is by connecting rod, main bearing shell, temperature sensor, the PLC programmable controller, the governor circuit relay is formed, it is characterized in that: have in the circumferentially all portion of main bearing shell and be not less than 2 temperature sensor mounted holes, the temperature sensor of identical parameters is installed in each temperature sensor mounted hole, each temperature sensor links to each other with the corresponding interface of PLC programmable controller by signal wire separately, and the output terminal of PLC programmable controller links to each other with the governor circuit relay of main control loop.Its principle of work is, each temperature sensor passes through signal wire separately, the temperature of its position is passed to the PLC programmable controller in real time, the PLC programmable controller is in advance by the program of setting, the temperature signal that each temperature sensor imports into is judged, in case the temperature exceeding standard of optional position just sends control signal, this control signal will make the governor circuit actuating of relay in the main control loop, and pressing machine is quit work immediately.Thereby avoid and further to raise by main shaft temperature, and the major accident of burning main shaft and main bearing shell to death that causes therefrom.
Beneficial effect: the present invention is owing to adopted the temperature sensor and the PLC programmable controller of electromechanical integration, available realization is to the real-time monitoring of main shaft temperature, can overcome existing pressing machine effectively and adopt the way of regularly and irregularly carrying out hand inspection, because human negligence inevitably exists, the influence of other outside cause in addition, bearing shell usually taking place because temperature anomaly, causes the equipment can't operate as normal, in addition can cause equipment badly damaged, until the serious consequence of scrapping.
