Technical field
The utility model relates to a kind of medicinal powder number percent detector of flux-cored wire.
Background technology
Along with Bridges in Our Country, the continuous propelling of highway and shipbuilding industry, welding profession is constantly development also, progressively improves for the requirement of welding material and welding technology.Flux-cored wire processes by the welding wire make-up machine, make-up machine pulls into cored solder wire by the different motor of a plurality of rotating speeds with steel band, in cored solder wire, add medicinal powder again, in order to make the medicinal powder number percent in the welding wire reach requirement, the cored solder wire that also will control by motor correspondingly this moment and the translational speed of flux-cored wire, then to the flux-cored wire circle around take-up.And widening day by day of the flux-cored wire usable range in the welding material just must require the manufacturing process of flux-cored wire and manufacturing equipment also progressively to improve, so the detector of relevant medicinal powder content also progressively occurs.
Traditional detection technique realizes that by eddy detection technology eddy detection technology is exactly an eddy current signal of accepting flux-cored wire.When quantitative change appears in testee, can cause the impedance variation of magnetic test coil, thereby influence the output of eddy current signal.The detection factors that influences medicinal powder content is a lot, mainly contains noncontinuity, signal to noise ratio (S/N ratio) of relative position, the cold working in the workpiece and heat treatment stress, the defective of conductivity, magnetic permeability, geometric configuration, temperature, magnetic test coil and testee etc.Because the interference of these factors makes common eddy detecting instrument very difficult to the signal processing analysis that detects, and also causes the zero migration of medicinal powder content.
The utility model content
The technical problems to be solved in the utility model provides a kind of all multifactor impacts that can not be subjected in the on-the-spot rugged surroundings, and testing result is the medicinal powder number percent detector of flux-cored wire more accurately.
In order to solve above technical matters, first kind of technical scheme that the utility model adopts is:
A kind of medicinal powder number percent detector of flux-cored wire, comprise first speed detector that is used to detect the cored solder wire motor speed, be used to detect the second speed detecting device of flux-cored wire motor speed, the A/D converter that is electrically connected with the output terminal of described first speed detector output terminal and second speed detecting device respectively, the controller that is electrically connected with described A/D converter output terminal, thus described first speed detector and second speed detecting device carry out the number percent that computing draws flux-cored wire medicinal powder content by controller after the information of gathering is converted to digital signal by A/D converter.
Preferably, this detector also comprises man-machine interface, and described man-machine interface and described controller are electrically connected.Described man-machine interface can show percent dynamic data and curve.
Further preferably, this detector also comprises the I/O equipment that is electrically connected with described controller, is connected with pilot lamp and or hummer on this I/O equipment.Man-machine interface is imported predetermined limit initial value etc. by man-machine interface, and controller compares number percent and the limit initial value that draws, and pilot lamp and hummer all can be realized reporting to the police.
Preferably, this detector also comprises the D/A converter that is electrically connected with described controller, is connected with registering instrument and or instrument on this D/A converter.Registering instrument can write down the situation of change of packing ratio.Pointer instrument is show percent dynamically.
Preferably, described controller is PLC.
The utility model compared with prior art, have following advantage: the utility model is by the collection to cored solder wire motor speed and flux-cored wire motor speed, by the controller computing, can realize accurately measuring under the duty situation of change of the inner medicinal powder number percent of flux-cored wire, and be not subjected to all multifactor impacts in the on-the-spot rugged surroundings of welding wire, testing result is more accurate.
Description of drawings
Accompanying drawing 1 is the theory diagram of the detector implemented according to the utility model.
Embodiment
As shown in Figure 1, a kind of process that is used for processing flux-cored wire, the medicinal powder number percent detector of detection flux-cored wire at make-up machine.Make-up machine comprises steel band motor, cored solder wire motor, flux-cored wire motor etc., by the speed discrepancy between cored solder wire motor and the steel band motor, steel band is pulled into cored solder wire, then by under the speed discrepancy state between cored solder wire motor and flux-cored wire motor, in cored solder wire, fill medicinal powder, make it to become flux-cored wire.The medicinal powder number percent detector of flux-cored wire comprises first speed detector that is used to detect the cored solder wire motor speed, be used to detect the second speed detecting device of flux-cored wire motor speed, the A/D converter that is electrically connected with the output terminal of described first speed detector output terminal and second speed detecting device respectively, the PLC controller that is electrically connected with described A/D converter output terminal, thus described first speed detector and second speed detecting device carry out the number percent that computing draws flux-cored wire medicinal powder content by the PLC controller after the information of gathering is converted to digital signal by A/D converter.
This detector also comprises man-machine interface, i.e. HMI, and described man-machine interface and described PLC controller are electrically connected.By man-machine interface can show percent dynamic data and curve, can also revise the upper limit, the lower limit data that are used for comparison.
This detector also comprises the I/O equipment that is electrically connected with described PLC controller, is connected with pilot lamp and hummer on this I/O equipment.As exceeded the upper and lower limit numerical range of man-machine interface input when number percent, just send warning message by pilot lamp and hummer.
