Description
Technical field
The utility model relates to warning device, is specifically related to a kind of online air supply line blast monitoring alarmer.
Background technology
Point welding process is the technological process that in the auto parts and components production run, several stamping parts or standard component assembly welding is become a functional weldment; And Joint Strength is to guarantee the high key link of weldment welding quality, and compressed-air actuated pressure is a key factor that influences Joint Strength.Lower compressed-air actuated pressure can cause welding electrode pressure on the low side, causes fully pressing when welding between workpiece and the workpiece, thereby is prone to quality of welding spot condition of poor such as fried point, burn through.Owing to lack the device of visual inspection compressed air pressure, when compressed air pressure was lower than setting, welding personnel can not find in time that compressed air pressure is not enough, thereby causes weldment to have mass defect in the existing spot-welding equipment.
Summary of the invention
The purpose of the utility model provides a kind of online air supply line blast monitoring alarmer; Can in time detect the not enough situation of compressed air pressure of the air supply line of flowing through; And in time report to the police through light, jingle bell; It is unusual to inform that in the very first time operating personnel's blast occurs, and avoids causing weldment to produce mass defect.
The described a kind of online air supply line blast monitoring alarmer of the utility model; The normal display lamp of air pressure, the air pressure that comprise electric control box, be located by connecting on the electric control box are crossed low warning lamp and power light; This power light is connected with power switch, electric protection air switch, and is connected with power supply terminal.
On electric control box, also be provided with pressure transducer, this pressure transducer is connected with an end of air feed pipe lateral, and the probe of pressure transducer stretches in the air feed pipe lateral, and the other end of air feed pipe lateral is connected with air feed pipe trunk line and communicates.
In electric control box, be provided with auxiliary reclay; One end of this auxiliary reclay is connected with an end of the microswitch of pressure transducer; The other end of microswitch is connected with power light one end, and the other end of auxiliary reclay is connected with the other end of power light.
One end of the normally closed contact of auxiliary reclay is connected with an end of the normal display lamp of air pressure, and the other end of the normal display lamp of air pressure is connected with power light one end, and the other end of the normally closed contact of auxiliary reclay is connected with the other end of power light.
The end that one end and the air pressure of the normally opened contact of auxiliary reclay is crossed low display lamp is connected, and the other end that air pressure is crossed low display lamp is connected with power light one end, and the other end of the normally opened contact of auxiliary reclay is connected with the other end of power light.
In electric control box, also be provided with the time relay, outside electric control box, also be provided with the warning electric bell.The end that one end and the air pressure of the time relay is crossed low display lamp is connected, and the other end of the time relay is connected with warning electric bell one end.Time through the adjustment time relay is provided with, the jingle bell time of control warning electric bell.
Pressure transducer plays the effect that compressed air pressure is converted to electric signal; The effect of reporting to the police through luminous form when air pressure is crossed low warning lamp and played compressed air pressure and be lower than setting; The time that control warning electric bell sends the sound is played in the effect of reporting to the police through the form of sending electric bell sound when the warning electric bell plays compressed air pressure and is lower than setting, the time relay.
When this online air supply line blast monitoring alarmer carries out the line installation; Pick out an air feed pipe lateral at the welding job scene through air feed pipe trunk line branch; Air feed pipe lateral pressure transducer is connected with pressure transducer, and the probe of pressure transducer stretches in the air feed pipe lateral.Insert the 220V alternating current to the inner power supply terminal of electric appliance control box from power supply simultaneously, this alarm is accomplished with the outside work that is connected.Then according to the gaseous tension that will monitor; The lower limit of adjustment pressure transducer; Close behind the electric control box power switch, the electrical power pilot lamp is bright, and this moment, online air supply line blast monitoring alarmer was in the duty of the compressed air pressure of keeping watch on air supply line.
The utility model is owing to have this kind structure, and when the pressurized air gaseous tension in the pipeline was higher than the lower limit of pressure transducer setting, the normal display lamp of air pressure glimmered with green warning lamp; When compressed-air actuated gaseous tension be lower than that pressure transducer sets lower limit the time; Air pressure is crossed low warning lamp and is glimmered with red warning lamp; And the warning electric bell sends the sound, and therefore this online air supply line blast monitoring alarmer can in time detect the not enough situation of compressed air pressure of the air supply line of flowing through.Cross low warning lamp with red flare and send chimes of doom when air pressure, remind the staff to stop immediately producing, thereby avoid causing weldment mass defect, and then reduce effectively and stop because the low product quality accident that produces of compressed-air actuated gaseous tension.
